Answer:
a. WS-Trust
Explanation:
WS-Trust can be defined as a WS-specification as well as OASIS standard that help to provides extensions to WS-Security, in order to facilitate a mechanism for issuing, renewing, as well as validating of security tokens which is why the aim and objectives of WS-Trust is to help and enable applications to construct trusted SOAP message exchanges.
Nevertheless WS-Trust enables the issuance as well as the dissemination of credentials within several and various trust domains.
A web service using the WS-Trust can be used for implementing the standards that encode the WS security to facilitate the mechanisms for issuing and reviewing the security tokens.
Hence e the option A is correct. The WS security token service is a service based on the mechanisms of the key exchange.Learn more about the following enhances WS-Security to facilitate.

If no other row matches, the router will select the ________ row as its best match. First Last either First or Last, depending on the circumstances neither First nor Last
Answer:
Last
Explanation:
Routing is a term in engineering which involves the process of selecting a path for traffic in a network or across multiple networks. It is applicable in circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. It is mostly used as a term for IP Routing.
Hence, in IP Routing, the first step is comparing the packet's destination IP address to all rows, followed by selecting the nest-match row. However, If no other row matches, the router will select the LAST row as its best match.
a. A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2, 048 sectors and there are 131, 072 (2^17) tracks per surface. A block holds 512 bytes. The disk is not "zoned." What is the total capacity of this disk?
b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (That, is, what is the capacity of one cylinder?)
Answer:
Explanation:
Given that:
number of surfaces on a hard disk = 4
number of sectors = 2048 sectors
number of tracks per surface = 131, 072 (2^17)
a block holds 512 bytes.
Since, 'The disk is not "zoned.".....
then, Number of bytes / sector = 512
a) What is the total capacity of this disk?
The total capacity of the disk is:[tex]= 4 \ surfaces \times 131072 \dfrac{tracks}{surfaces} \times 2048 \dfrac{sector}{tracks} \times 512 \dfrac{bytes}{sector}[/tex]
[tex]= 5.49755814\times 10^{11} \ bytes[/tex]
= 549755814 KB ( kilobytes)
= 549755.814 MB (megabytes)
=549.755814 GB (gigabytes)
b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (i.e what is the capacity of one cylinder?)
The capacity of one cylinder can be estimated by determining the capacity of one surface and the capacity of one track.
The capacity of one surface = [tex]131072\dfrac{tracks}{surface} \times 2048 \dfrac{sector}{tracks} \times 512\dfrac{bytes}{sector}[/tex]
The capacity of one surface = [tex]1.37438953 \times 10^{11[/tex] byte = 137.44 GB
Capacity of one track = 2048 sectors/track × 512 bytes/sector
Capacity of one track = 1048576 Bytes/track
Capacity of one track =1048 KB/track
Capacity of one track ≅ 1 MB/track
Since the hard disk contains four surfaces
∴
capacity of one cylinder = 1 MB/track × 4 track/cylinder
capacity of one cylinder = 4 MB

Timestamp and Validation schedulers can be used to remove physically unrealizable behaviour. 3. Timestamp and Validation schedulers guarantee serializability. 4. Timestamp and Validation schedulers perform most effectively on transactions that perform writes.
Answer:
3. Timestamp and Validation schedulers guarantee serializability.
Explanation:
Timestamp is a sequence of information encoded when a certain event occurs at a given time that information is decoded and message is identified. Time schedulers is optimistic scheduler and it removes physically unrealizable behavior. Timestamp cannot guarantee serializability. It can detect unrealizable behavior.
A pen testing method in which a tester with access to an application behind its firewall imitates an attack that could be caused by a malicious insider.
a. True
b. False
Answer:
a. True
Explanation:
The statement that a pen testing method or penetration test in which a tester who has a means of entry to an application behind its firewall imitates an attack that could be caused by a malicious insider.
A penetration test, which is also refer to as a pen test, pentest or ethical hacking, is an approved simulated cyberattack done on a computer system, performed in order to evaluate the security of the system. The test is carried out to identify both weaknesses or vulnerabilities including the potential for unauthorized parties to penetrate to the system's features and data.
The main purpose of performing this test is to identify any vulnerability in a system's defenses which attackers may take advantage of.
Suppose that a main method encounters the statement t3.join(); Suppose that thread t3's run() method has completed running. What happens?
A. The main method waits for all running threads to complete their run() methods before proceeding.
B. The main method waits for any other thread to complete its run() method before proceeding
C. The main method proceeds to the next statement following the t3.join(); statement
D. Thread t 3 is re-started
E. All threads except t3 that are running are terminated
Answer:
C. The main method proceeds to the next statement following the t3.join(); statement
Explanation:
join() method allows the thread to wait for another thread and completes its execution. If the thread object is executing, then t3.join() will make that t is terminated before the program executes the instruction. Thread provides the method which allows one thread to another complete its execution. If t is a thread object then t.join() will make that t is terminated before the next instruction. There are three overloaded functions.
join()
join(long mills)
join(long millis, int Nanos)
If multiple threads call the join() methods, then overloading allows the programmer to specify the period. Join is dependent on the OS and will wait .

Because Java byte code is the same on all computers, compiled Java programs Group of answer choices Cannot run on Linux systems Must be re-compiled for each different machine it is run on Are highly portable Are non-existent
Answer:
Are highly portable.
Explanation:
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995.
Java was designed by a software engineer called James Gosling and it is originally owned by Oracle. Also, worthy of mention is the fact that Java was originally known as Oak.
Generally, Java as a software application usually are developed having a ".jar", ".class" or ".java" filename extensions.
Because Java byte code is the same on all computers, compiled Java programs are highly portable. This simply means that, the Java byte code was designed such that it has very few implementation dependency, thus, once the code is written, it can run on all computer platforms that supports the Java programming language.
Hence, the Java byte code is a write once, run anywhere software program.
The Java byte code instructions are read and executed by a computer program known as a Java Virtual Machine (JVM).
Additionally, Java program is used for developing varieties of applications such as, mobile, desktop, games, web and application servers etc.

Write a date transformer program using an if/elif/else statement to transform a numeric date in month/day format to an expanded US English form and an international Spanish form; for example, 2/14 would be converted to February 14 and 14 febrero
I wrote it in Python because it was quick so i hope this is helpful
Answer:
date = input('Enter Date: ')
split_date = date.split('/')
month = split_date[0]
day = split_date[1]
if month == '1':
english_month = 'January'
spanish_month = 'Enero'
elif month == '2':
english_month = 'February'
spanish_month = 'Febrero'
elif month == '3':
english_month = 'March'
spanish_month = 'Marzo'
elif month == '4':
english_month = 'April'
spanish_month = 'Abril'
elif month == '5':
english_month = 'May'
spanish_month = 'Mayo'
elif month == '6':
english_month = 'June'
spanish_month = 'Junio'
elif month == '7':
english_month = 'July'
spanish_month = 'Julio'
elif month == '8':
english_month = 'August'
spanish_month = 'Agosto'
elif month == '9':
english_month = 'September'
spanish_month = 'Septiembre'
elif month == '10':
english_month = 'October'
spanish_month = 'Octubre'
elif month == '11':
english_month = 'November'
spanish_month = 'Noviembre'
elif month == '12':
english_month = 'December'
spanish_month = 'Diciembre'
US_English = f'{english_month} {day}'
International_Spanish = f'{day} {spanish_month}'
print(f'US English Form: {US_English}')
print(f'International Spanish Form: {International_Spanish}')
Input:
3/5
Output:
US English Form: March 5
International Spanish Form: 5 Marzo
Explanation:
You start by taking input from the user then splitting that at the '/' so that we have the date and the month in separate variables. Then we have an if statement checking to see what month is given and when the month is detected it sets a Spanish variable and an English variable then prints it to the screen.
Hope this helps.
In the Programming Process which of the following is not involved in defining what the program is to do:_____________ Group of answer choices
a. Compile code
b. Purpose
c. Output
d. Input
e. Process
Answer:
a. Compile code
Explanation:
In programming process, the following are important in defining what a program is to do;
i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program. The purpose of a program should be defined in the program.
ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.
iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.
iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.
Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.
It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program.
A. True
B. False
Answer:
True
Explanation:
It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program is a "true statement" or the first option. It is very natural for a programmer/developer to come up with test that will run through every possible outcome in a program. Doing so will help the developer find things that might cause problems with the program in later time.
Hope this helps.
The answer to the question about the feasibility of a programmer to always come up with test cases that run through every possible path in a program is:
NoWhat is a Test Case?This refers to the set of actions which a programmer performs to find out if his software or program passes the system requirements in order to work properly.
With this in mind, we can see that while in some cases, it is possible for the programmer to come up with test cases, but it is not feasible in all cases as there can be hardware error which a virtual machine cannot solve.

Explanation:
As the above code, it is clear defines that python doesn't support the method overloading because More than one method can't be specified in a python class with the same name and python method arguments have no type. The single argument method may be named using an integer, a series, or a double value, that's why we can say that it is not allowed.Shovels and Shingles is a small construction company consisting of 12 computers that have Internet access.

Write down an encryption solution that best prevents a competitor from receiving confidential information and justify the recommendation.
Answer:
The Encryption solution that best prevents a competitor from receiving confidential information is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
Explanation:
Solution:
From my own perspective the encryption solution that i will use that prevents s a competitor from receiving confidential information and justify the recommendation is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
This is because in this case we have to share data confidentially (information need to be hidden from Unauthorized security access. also these provides the Transport Layer security that we needed in above example above.
The purpose of these protocol is to provide server and client authentication, Data confidentiality,and Data integrity (protected from unauthorized change). Application Layer client/server program such as HTTP that uses the service of TCP can encapsulate their data in SSL Packets.
SSL (Secure Socket Layer): is defined as the normal technology for protecting an internet connection secure and defend any sensitive data that is being sent between two systems, and not allowing criminals from reading and changing any information sent, including potential personal details.
TLS (Transport Layer security): It is a procedure that allows data integrity and privacy over Internet communications.
Write a program that asks the user to input a positive integer and then calculates and displays the factorial of the number. The program should call a function named getN
Answer:
The program is written in python and it doesn't make use of any comment;
(See explanation section for line by line explanation)
def getN(num):
fact = 1
for i in range(1, 1 + num):
fact = fact * i
print("Factorial: ",fact)
num = int(input("Number: "))
if num < 0:
print("Invalid")
else:
getN(num)
Explanation:
The function getNum is defined here
def getN(num):
Initialize the result of the factorial to 1
fact = 1
Get an iteration from 1 to the user input number
for i in range(1, 1 + num):
Multiply each number that makes the iteration
fact = fact * i
Print result
print("Factorial: ",fact)
Ths line prompts user to input number
num = int(input("Number: "))
This line checks if user input is less than 0; If yes, the program prints "Invalid"
if num < 0:
print("Invalid")
If otherwise, the program calls the getN function
else:
getN(num)

b = float(input("User Input: "))
while not b==0:
newlist.append(b)
b = float(input("User Input: "))
newlist.sort()
print("Largest element is:", newlist[-1])
Explanation:
This line gives the user instruction on how to populate the list and how to stop
print("Enter elements into the list. Enter 0 to stop")
This line creates an empty list
newlist = []
This line enables the user to input numbers; float datatype was used to accommodate decimal numbers
b = float(input("User Input: "))
The italicized gets input from the user until s/he enters 0
while not b==0:
newlist.append(b)
b = int(input("User Input: "))
This line sorts the list in ascending order
newlist.sort()
The last element of the sorted list which is the largest element is printed using the next line
print("Largest element is:", newlist[-1])

#Write a function called 'string_type' which accepts one #string argument and determines what type of string it is. # # - If the string is empty, return "empty". # - If the string is a single character, return "character". # - If the string represents a single word, return "word". # The string is a single word if it has no spaces. # - If the string is a whole sentence, return "sentence". # The string is a sentence if it contains spaces, but # at most one period. # - If the string is a paragraph, return "paragraph". The # string is a paragraph if it contains both spaces and # multiple periods (we won't worry about other # punctuation marks). # - If the string is multiple paragraphs, return "page". # The string is a paragraph if it contains any newline # characters ("\n"). # #Hint: think carefully about what order you should check #these conditions in. # #Hint 2: remember, there exists a count() method that #counts the number of times a string appears in another #string. For example, "blah blah blah".count("blah") #would return 3.
Answer:
I am writing a Python program:
def string_type(string):
if string=="": //if the string is empty
return "empty"
elif string.count(".")>1: #if the period sign occurs more than once in string
if string.count("\n"): #checks if the new line occurs in the string
return "page" #if both the above cases are true then its a page
return "paragraph" # if the period sign condition is true then its a para
elif string.count(" ")>=1: #if no of spaces in string occur more than once
return "sentence" #returns sentence
elif len(string)==1: # if length of the string is 1 this
return "character" #returns character
else: #if none of the above conditions is true then its a word
return "word" #returns word
Explanation:
def string_type(string): this is the definition of method string_type which takes a string as argument and determines whether the type of string is a word, paragraph, page, sentence or empty.
if string=="" this if condition checks if the string is empty. If this condition is true then the method returns "empty"
elif string.count(".")>1 This condition checks if the string type is a paragragh
string.count(".")>1 and if string.count("\n") both statements check if the string type is a page.
Here the count() method is used which is used to return the number of times a specified string or character appears in the given string.
Suppose the string is "Paragraphs need to have multiple sentences. It's true.\n However, two is enough. Yes, two sentences can make a paragraph."
The if condition first checks if count(".")>1 which means it counts the occurrence of period i.e. "." in the string. If the period occurs more than once this means it could be a page. But it could also be a paragraph so in order to determine the correct string type another if statement if string.count("\n") inside elif statement determines if the string is a page or not. This statement checks the number of times a new line appears in the string. So this distinguishes the string type paragraph from string type page.
elif string.count(" ")>=1: statement determines if the string is a sentence. For example if the string is "i love to eat apples." count() method counts the number of times " " space appears in the string. If the space appears more than once this means this cannot be a single word or a character and it has more than one words. So this means its a sentence.
elif len(string)==1: this else if condition checks the length of the string. If the length of the string is 1 this means the string only has a single character. Suppose string is "!" Then the len (string) = 1 as it only contains exclamation mark character. So the method returns "character" . If none of the above if and elif conditions evaluates to true then this means the string type is a word.
Answer:
def string_type(string):
if string=="": //if the string is empty
return "empty"
elif string.count(".")>1: #if the period sign occurs more than once in string
if string.count("\n"): #checks if the new line occurs in the string
return "page" #if both the above cases are true then its a page
return "paragraph" # if the period sign condition is true then its a para
elif string.count(" ")>=1: #if no of spaces in string occur more than once
return "sentence" #returns sentence

Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates.
Answer:
Here is the Python code.
import csv
inputfile = input("Enter name of the file: ")
count = {}
with open(inputfile, 'r') as csvfile:
csvfile = csv.reader(csvfile)
for line in csvfile:
for words in line:
if words not in count.keys():
count[words] = 1
else:
count[words] + 1
print(count)
Explanation:
I will explain the code line by line.
import csv here the css is imported in order to read the file using csv.reader() method
inputfile = input("Enter name of the file: ") This statement takes the name of the input file from the user
count = {} this is basically a dictionary which will store the words in the file and the number of times each word appears in the file.
with open(inputfile, 'r') as csvfile: This statement opens the inputfile using open() method in read mode. This basically opens the input file as csv type
csvfile = csv.reader(csvfile) This statement uses csv.reader() method to read the csv file contents.
for line in csvfile: This outer for loop iterates through each line of the file
for words in line: This inner loop iterates through each word in the line
if words not in count.keys(): This if condition checks if the word is not in the dictionary already. The dictionary holds key value pair and keys() method returns a list of all the keys of dictionary
count[words] = 1 if the word is not present already then assign 1 to the count dictionary
co unt[words] + 1 if the word is already present in dictionary increment count of the words by 1. Suppose the input file contains the following words:
hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy
Then because of co unt[words] + 1 statement if the word appears more than once in the file, then it will not be counted. So the output will be:
{' cat': 1, ' man': 1, ' dog': 1, ' woman': 1, ' Hello': 1, ' hey': 1, ' boy': 1, 'hello': 1, ' Cat': 1}
But if you want the program to count those words also in the file that appear more than once, then change this co unt[words] + 1 statement to:
count[words] = count[words] + 1
So if the word is already present in the file its frequency is increased by 1 by incrementing 1 to the count[words]. This will produce the following output:
{' Cat': 1, ' cat': 2, ' boy': 2, ' woman': 1, ' dog': 2, ' hey': 2, ' man': 2, ' Hello': 1, 'hello': 1}
You can see that cat, boy, dog and hey appear twice in the file.
print(count) This statement prints the dictionary contents with words and their frequencies.
The program with its output is attached.
The program is an illustration of file manipulations.
File manipulations involve reading from and writing into files.
The program in Python, where comments are used to explain each line is as follows:
#This imports csv module
import csv
#This initializes a dictionary
kounter = {}
#This gets input for the file name
fname = input("Filename: ")
#This opens and iterates through the file
with open(fname, 'r') as cfile:
#This reads the csv file
cfile = csv.reader(cfile)
#This iterates through each line
for line in cfile:
#This iterates through each word on each line
for words in line:
#This counts the occurrence of each word
if words not in kounter.keys():
kounter[words] = 1
else:
kounter[words] + 1
#This prints the occurrence of each word
print(kounter)

print('FIXME: Finish compute_avg()')
return -1
Explanation:
A stub is a small function or a piece of code which is sometimes used in program to test a function before its fully implemented. It can also be used for a longer program that is to be loaded later. It is also used for a long function or program that is remotely located. It is used to test or simulate the functionality of the program.
The first stub for the function get_user_num() displays FIXME: Finish get_user_num() and then it returns -1.
The seconds stub for the function compute_avg() displays the FIXME: Finish compute_avg() and then it returns -1.
Here with each print statement, there is function name after this FIXME: Finish line. The first function name is get_user_num and the second is compute_avg().
Next the function get_user_num() is called twice and function compute_avg() followed by a print statement: print('Avg:', avg_result) which prints the result. So the program as a whole is given below:
def get_user_num():
print('FIXME: Finish get_user_num()')
return -1
def compute_avg(user_num1, user_num2):
print('FIXME: Finish compute_avg()')
return -1
user_num1 = 0 # the variables are initialized to 0
user_num2 = 0
avg_result = 0
user_num1 = get_user_num() #calls get_user_num method
user_num2 = get_user_num()
avg_result = compute_avg(user_num1, user_num2)
print('Avg:', avg_result)
The method get_user_num() is called twice so the line FIXME: Finish get_user_num() is printed twice on the output screen. The method compute_avg() is called once in this statement avg_result = compute_avg(user_num1, user_num2) so the line FIXME: Finish compute_avg() is printed once on the output screen. Next the statement print('Avg:', avg_result) displays Avg: -1. You can see in the above program that avg_result = compute_avg(user_num1, user_num2) and compute_avg function returns -1 so Avg= -1. The program along with the produced outcome is attached.
Your on-premises hosted application uses Oracle database server. Your database administrator must have access to the database server for managing the application. Your database server is sized for seasonal peak workloads, which results in high licensing costs. You want to move your application to Oracle Cloud Infrastructure (OCI) to take advantage of CPU scaling options. Which database offering on OCI would you select?
Answer:
Bare metal DB systems
Explanation:
Oracle Call Interface OCI is comprehensive system which is native C language interface to Oracle Database for custom applications. The bare metal database system requires more compute node processing power. Customers are not given OS logons or SYSDBA in Oracle autonomous applications which prevents phishing attacks.
A network technician is designing a network for a small company. The network technician needs to implement an email server and web server that will be accessed by both internal employees and external customers. Which of the following would best secure the internal network and allow access to the needed servers?
A. Implementing a site-to-site VPN for server access.B. Implementing a DMZ segment for the server.C. Implementing NAT addressing for the servers.D. Implementing a sandbox to contain the servers.
Answer:
Option A (Implementing a site-to-site VPN for server access) seems to be the correct choice.
Explanation:
A site-to-site configuration is something that a single Open VPN network links several more separate networks linked. Technologies through one network will access machines in all the other computer systems in that connection model, including conversely. Implementing this would be extremely straightforward, for as much further even though Access Server was indeed implicated.The much more challenging aspect happens when interacting regarding firewalls including privacy filtering methods, as well as modifying the forwarding table in internet gateways, as several of them from different manufacturers but instead prototypes which they may not be able to log many of these.This rather gateway device uses an Open VPN with a Linux VPN client, to create a connection between various channels. If someone's server hardware is also measured accurately then perhaps a site-to-site configuration could be accomplished which works straightforwardly throughout all systems in both cable systems.Other choices are not related to the given instance. So that Option A would be the right one.
