Which of the following would allow for the QUICKEST restoration of a server into a warm recovery site in a case in which server data mirroring is not enabled?a. Full backupb. incremental backupc. Differential back upd. Snapshot
Answer: C. Differential backup
Explanation: There are several ways od ensuring the preservation and storage of data even cases of disaster, one of such ways is data data mirroring which allows data to be replicated or copied in real time and several backup options. In cases where there there is need to restore a server, the warm recovery site provides a data or disaster recovery option used to mitigate the effect of data loss on organization. In the absence of data mirroring, differential backup option, provides the quickest recovery option as it only requires changes in the data stored after the last full backup. These speed experieced should be expected due to the relatively low data been dealt with rather than the entire data.

The functions of mat plot lib enable it to function similarly to MATLAB. Each function modifies a figure in some way, such as by producing a figure, a plotting region within a figure, some lines within a plotting area, labelling the plot, etc.
Mat plot lib would be useless for processing numbers if it could only deal with lists. In arrays, you typically use integers. In actuality, all sequences undergo internal array conversion. The example that follows shows how to use arrays to draw multiple lines with various format styles in a single function call.

If the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencinga) trueb) false
Answer:
A. True.
Explanation:
Authentication in computer technology can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.
Hence, if the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencing.
This simply means that, when a user enters his or her private key (password); the authenticator matches the private key to the uniquely defined credentials. Permission and access is granted by the authorization system right after a successful authentication.

How can you determine which package is better: openssh-server-5.3p1-118.1.el6_8.x86_64 or openssh-server-6.6p1-1.el6.x86_64
Answer:
The best by the concept of the newest is the better is the openssh-server-6.6p1-1.el6.x86_64.
Explanation:
The openssh-server-5.3p1-118.1.el6_8.x86_64 and the openssh-server-6.6p1-1.el6.x86_64 are named version of a server which is the openssh- server.
The first server is the later version is the 5.3p1 version( which is seen after the server name ), while the former is the 6.6p1 version. They both use the Linux operating systems version RHEL 6 and 6.8 and are for 32-bit and 64-bit computers (.x86_64).
So, judging by the newest, the version 6.6 is the better server of the two.
What are the advantages, strengths and/or weaknesses of remote access methods and techniques such as RADIUS, RAS, TACACS+ and VPN?
Answer:
they store authentication details in the remote server and its retrieval is encrypted. But it can also be very slow when the network signal is down.
Explanation:
Private IP network like in a small or enterprise company needs access control methods to prevent unwanted access to files by unauthorized employees. The regular router ssh authentication is good for a small company but it has no backup storage to hold user login details and easily be hacked by attackers. So the AAA policy is adopted to prevent this. it stands for authentication, authorization and accounting, and uses protocols like the RADIUS, TACAS+, VPN, etc, to prevent unwanted access. it is fast and saves all the login details of all the employees in the network, but experiences slow or no authentication when network is down.

Sample output with input:
8 8 16 32 64 1 nu
1 insects = int(input()) Must be
2
3 Your solution goes here
Answer:
1)
Add this while statement to the code:
while(keep_going!='n'):
#the program keeps asking user to continue bidding until the user enter 'n' to stop.
2)
Here is the code for ACTIVITY 53.3. While loop: Insect growth:
num_insects = int(input())
while num_insects <= 100:
print(num_insects, end=' ')
num_insects = num_insects * 2
Explanation:
Here is the complete code for 1)
import random
random.seed (5)
keep_going='-'
next_bid = 0
while(keep_going!='n'):
next_bid = next_bid + random.randint(1, 10)
print('I\'ll bid $%d!' % (next_bid))
print('continue bidding?', end='')
keep_going = input()
Here the the variable keep_going is initialized to a character dash keep_going='-'
The statement keep_going = input() has an input() function which is used to take input from user and this input value entered by user is stored in keep_going variable. while(keep_going!='n'): is a while loop that keeps iterating until keep_going is not equal to 'n'. print('continue bidding?', end='') statement prints the continue bidding? message on the output screen. For example the user enters 'y' when this message appears on screen. So keep_going = 'y' . So the operation in this statement next_bid = next_bid + random.randint(1, 10) is executed in which next_bid is added to some randomly generated integer within the range of 1 to 10 and print('I\'ll bid $%d!' % (next_bid)) prints the result on the screen. Then the user is prompted again to continue biffing. Lets say user enters 'n' this time. So keep_going = 'n'. Now the while loop breaks when user enters 'n' and the program ends.
2)
num_insects = int(input()) #the user is prompted to input an integer
while num_insects <= 100: #the loop keeps iterating until value of num_insects exceeds 100
print(num_insects, end=' ') #prints the value of num_insects
num_insects = num_insects * 2 #the value of num_insects is doubled
For example user enters 8. So
num_insects = 8
Now the while loop checks if this value is less than or equal to 100. This is true because 8 is less than 100. So the body of while loop executes:
print(num_insects, end=' ') statement prints the value of num_insects
So 8 is printed on the screen.
num_insects = num_insects * 2 statement doubles the value of num_insects So this becomes:
num_insects = 8 * 2
num_insects = 16
Now while loop checks if 16 is less than 100 which is again true so next 16 is printed on the output screen and doubled as:
num_insects = 16 * 2
num_insects = 32
Now while loop checks if 32 is less than 100 which is again true so next 32 is printed on the output screen and doubled as:
num_insects = 32 * 2
num_insects = 64
Now while loop checks if 64 is less than 100 which is again true so next 64 is printed on the output screen and doubled as:
num_insects = 64 * 2
num_insects = 128
Now while loop checks if 128 is less than 100 which is false so the program stops and the output is:
8 16 32 64
The programs along with their output is attached.

What is the result if you add two decimal numbers (45+216), expressed in binary using 8-bit unsigned precision?
Answer:
261
Explanation:
Adding up two decimal numbers ( 45 + 216 ) expressed in binary using 8-bit unsigned precision
first we express the decimal numbers in 8-bit unsigned precision :
45 = 32 + 8 + 4 + 1 = 2^5 + 2^3 + 2^2 + 2^0 = 00101101
216 = 2^7 + 2^6 + 2^4 + 2^3 = 11011000
Adding the numbers together = 00101101
+ 11011000
= 100000101 = 261 ( an overflow occurred )
note : The maximum value that can be expressed with 8-bit unsigned precision is = 2^8 - 1 = 256
Regular Expression Replace Challenge
In this challenge you will use the file regex_replace_challenge_student.py to:
Write a regular expression that will replace all occurrences of:
regular-expression
regular:expression r
egular&expression
In the string: This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression
Assign the regular expression to a variable named pattern
Using the sub() method from the re package substitute all occurrences of the 'pattern' with 'substitution'
Assign the outcome of the sub() method to a variable called replace_result
Output to the console replace_results
Answer:
Here is the Python program:
import re # module for regular expressions
search_string='''This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression''' #string to search for a regular expression
pattern = "regular.expression" #Assigns the regular expression to pattern
substitution="regular expression" #substitute all occurrences of pattern with regular expression string stored in substitution
replace_results = re.sub(pattern,substitution,search_string) # sub() method from the re package to substitute all occurrences of the pattern with substitution
print(replace_results) #Assigns the outcome of the sub() method to this variable
Explanation:
This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression
search_string='''This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression'''
The following statement assigns the regular expression to a variable named pattern .
pattern = "regular.expression"
The following statement is used to substitute the pattern (regular expression) in the search_string by replacing all occurrences of "regular expression" sub-string on search_string.
substitution="regular expression"
The following statement uses re.sub() method to replace all the occurrences of a pattern with another sub string ("regular expression"). This means in search_string, the sub strings like regular expression, regular-expression, regular:expression or regular&expression are replaced with string "regular expression". This result is stored in replace_results variable. Three arguments are passed to re.sub() method:
sub string to replace i.e. pattern
sub string to replace with i.e. substitution
The actual string i.e. search_string
replace_results = re.sub(pattern,substitution,search_string)
The following print statement displays the output of replace_results
print(replace_results)
The output of the above program is:
This is a string to search for a regular expression like regular expression or regular expression or regular expression or regular expression
Hardening FSO infrastructure includes all of the following except:______.
A. FSOs should have backstops to prevent overshoot to neighboring office windows orrooftops
B. They should be mounted in easy to reach places.
C. They should have physical security such as keycard and/or biometric access.
D. They should be protected by motion detection systems and motion-activated video.
Answer:
Hardening FSO infrastructure includes all of the following except:______.
A. FSOs should have backstops to prevent overshoot to neighboring office windows or rooftops.
Explanation:
FSO means a floating storage and offloading vessel. It is a simplified version of a floating production, storage, and offloading (FPSO) unit. FSO vessels are mainly floating vessels used by the offshore oil and gas industry for the storage of oil. Unlike the more advanced FPSO it cannot be used for the production and processing of hydrocarbons, and storage of oil. Since FSOs are installed offshore storage and offloading vessels, there is no need to harden the infrastructure by having "backstops to prevent overshooting to neighboring office windows or rooftops."

External network security threats can include management failure to support organization-wide security awareness, inadequate security policies, and unenforced security procedures.
A. True
B. False
Answer:
B. False
Explanation:
External security threat can be defined as any threats coming outside the company's computer network operation, usually carried out with negative or hostile intent for the purpose of stealing information or distracting the flow of operation. For example, Virus Attack
However, given that the question talked about the "management failure to support organization-wide security awareness, inadequate security policies, and unenforced security procedures."
Hence, this is not an External Security Threat, which means, the correct answer is FALSE.
Which the following is NOT a reason why it is difficult to defend against today's attackers? a. increased speed of attacks b. simplicity of attack tools c. greater sophistication of defense tools d. delays in security updating
Answer:
The correct answer to the question is OPTION C "greater sophistication of defense tools"
Explanation:
An attacker is the individual or organization whose activities are illegal because they usually aim at ''stealing" people's information or getting access to their accounts without prior knowledge of the victim.
Atimes, website developers make mistakes thereby exposing files on the web server outside of the directory of the website. This files are readable by attackers who capitalize of the mistake who use command injection to carryout an attack, while some attackers use scripts or programs developed by others to attack computer systems and networks.
increased speed of attacks makes it difficult to secure computers from attackers beacause, attackers use modern simple tools that are fast such that it can quickly scan systems for weaknesses and expose the vulnerability to carryout an attack.
Describe three (3) software packages that can be used to capture data?
Answer:
SingleClick
SingleClick is an Optical Character Recognition (OCR) tool that can be used to capture machine produced characters in low volume ad-hoc capture applications and populating a line of business application.
OCR (Optical Character Recognition)
OCR as a technology provides the ability to successfully capture machine produced characters in preset zones or, full page. OCR systems can recognise many different OCR fonts, as well as typewriter and computer-printed characters. Dependent upon the capabilities of the particular OCR product, this can be used to capture low to high volumes of data, where the information is in consistent location(s) on the documents.
ICR (Intelligent Character Recognition)
ICR is the computer translation of hand printed and written characters. Data is entered from hand-printed forms through a scanner, and the image of the captured data is then analysed and translated by sophisticated ICR software. ICR is similar to optical character recognition (OCR) but is a more difficult process since OCR is from printed text, as opposed to handwritten characters.

Answer:
The program written in python is as follows
persons = []
most = 0
personindex = 0
for i in range(1,11):
print("Person ",i)
pancake = int(input(": "))
persons.append(pancake)
if pancake > most:
most = pancake
personindex = i
print("Person ",personindex," ate most pancakes")
Explanation:
This line initializes an empty list
persons = []
This line initializes variable most to 0
most = 0
This line initializes variable personindex to 0
personindex = 0
This line iterates from 1 to 10
for i in range(1,11):
The next two line prompts user for input
print("Person ",i)
pancake = int(input(": "))
This line inserts the user input to the created list "persons"
persons.append(pancake)
The next if statement checks for the person with the most pancakes
if pancake > most:
most = pancake
personindex = i
This line prints the person with most pancakes
print("Person ",personindex," ate most pancakes")
