Answer:
In many UNIX/Linux data and configuration files are "fields". Sometimes these fields are separated by:
O tabs
O comma (,)
O colon (:)
Explanation:
A UNIX/Linux data and configuration file is a local program file that controls the operation of the program. Such files are usually static and are not created to be in executable binary. The files are stored in subdirectories. Backticks are not used to separate fields. But tabs, commas, and colons can be freely used. Configuration files, which are coded, provide the required parameters and initial settings to operate computer applications. Data files are not executable like configuration files but are used by applications as input and output data to be read or viewed.
Suppose you were charged with putting together a large LAN to support IP telephony (only) and that multiple users may want to carry on a phone call at the same time. Recall that IP telephony digitizes and packetizes voice at a constant bit rate when a user is making an IP phone call. How well suited are these four protocols for this scenario
Answer:
TDMA: Time-division multiple access (TDMA) will operate effectively.
CSMA: Carrier-sense multiple access (CSMA) will NOT operate properly.
Slotted Aloha: Slotted Aloha will NOT perform effectively.
Token passing: Token passing will operate effectively.

Token passing:
Provide a brief explanation of each answer.
The explanation of the answers is now provided as follows:
TDMA: Time-division multiple access (TDMA) will operate effectively in this situation because it provides a consistent bit rate service of one slot every frame.
CSMA: Because of collisions and a changing amount of time to access the channel, Carrier-sense multiple access (CSMA) will NOT operate properly in this situation. Also, the length of time it takes to access a channel is not limited.
Slotted Aloha: Just like CSMA, Slotted Aloha will NOT perform effectively in this situation because of collisions and a different amount of time to access the channel. Also, the length of time it takes to access a channel is limitless.
Token passing: Token passing will operate effectively in this case because each station has a turn to transmit once per token round, resulting in a service with an effectively constant bit rate.

Will has been asked to recommend a protocol for his company to use for a VPN connection to the cloud service provider that his company uses. Which of the following protocols could he rule out as options for this connection?
a. IKEv2
b. TFTP
c. L2TP
d. GRE
Answer:
The protocols that Will could rule out as options for this connection are:
b. TFTP
d. GRE
Explanation:
A virtual private network (VPN) delivers encrypted connection over the Internet to prevent unauthorized data access, thereby facilitating remote work and the transmission of sensitive data.
IKEv2 (Internet Key Exchange version 2) and Layer Two Tunneling Protocol (L2TP) are secure encryption protocols that enable virtual private network (VPN).
Trivial File Transfer Protocol (TFTP) is not encrypted for receiving and sending files but a simple boot-loading File Transfer Protocol.
Generic routing encapsulation (GRE) tunnels do not encrypt data and are not secure unless used with other secure tunnelling protocols.

Which of the following describes this capability?
a. Continuity
b. Adaptability
c. Vertical scaling
d. Horizontal scaling
Answer:
The description of this capability is:
d. Horizontal scaling
Explanation:
The capability that Brandon has achieved is horizontal scaling, which involves the increasing of the resources of cloud applications to meet his increasing demand for cloud services. Vertical scaling involves the addition or subtraction of power to a cloud server, which practically upgrades the memory, storage, or processing power. But to scale horizontally, more resources are added or subtracted. The purpose of horizontal scaling is to spread out or in the workload of existing resources and either increase or decrease overall performance and capacity.

Consider the following generalization of the Activity Selection Problem: You are given a set of n activities each with a start time si , a finish time fi , and a weight wi . Design a dynamic programming algorithm to find the weight of a set of non-conflicting activities with maximum weight.
Answer:
Assumption: Only 1 job can be taken at a time
This becomes a weighted job scheduling problem.
Suppose there are n jobs
Sort the jobs according to fj(finish time)
Define an array named arr to store max profit till that job
arr[0] = v1(value of 1st job)
For i>0. arr[i] = maximum of arr[i-1] (profit till the previous job) or wi(weight of ith job) + profit till the previous non-conflicting job
Final ans = arr[n-1]
The previous non-conflicting job here means the last job with end timeless than equal to the current job.
To find the previous non-conflicting job if we traverse the array linearly Complexity(search = O(n)) = O(n.n) = O(n^2)
else if we use a binary search to find the job Complexity((search = O(Logn)) = O(n.Log(n))

Write a program that solves the following problem:
One marker costs 80 cents. A package of five markers costs $3.50. This encourages people to buy complete packages rather than having to break packages open. The tax is 6.5% of the total. The shipping cost is 5% of the total (before tax). Your program will prompt for a number of markers (an integer). It will calculate and display:
⢠The number of complete packages of markers
⢠The number of separate markers (hint: use // and %)
⢠The cost for the markers before shipping and tax
⢠The cost of shipping
⢠The cost of tax
⢠The total cost of the markers after shipping and tax are added (the grand total)
Answer:
def main():
singleMarkerPrice = 0.80
packageOfMarkersPrice = 3.50
tax = 0.065
shipping = 0.050
userInput = int(input("How many markers do you want? "))

singleMarkers = userInput % 5
# Just for syntax so if the single marker amount is one, it prints package instead of packages
if amountOfPackages == 1:
print("You have " + str(int(amountOfPackages)) + " complete package")
else:
print("You have " + str(int(amountOfPackages)) + " complete packages")
# Just for syntax so if the single marker amount is one, it prints marker instead of markers
if singleMarkers == 1:
print("You have " + str(int(singleMarkers)) + " single marker")
else:

Answer:
payload
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
The encapsulating security payload (ESP) protocol is a standard protocol that provides secrecy for the contents (data) transmitted via network communications, as well as system-to-system authentication and data integrity verification so as to prevent unauthorized access.
Basically, the encapsulating security payload (ESP) protocol is a transport layer protocol that provides data confidentiality, integrity and authentication in IPv6 and IPv4 protocols.
What happens when a dataset includes records with missing data?
Answer:
However, if the dataset is relatively small, every data point counts. In these situations, a missing data point means loss of valuable information. In any case, generally missing data creates imbalanced observations, cause biased estimates, and in extreme cases, can even lead to invalid conclusions.
It makes data analysis to be more ambiguous and more difficult.
Missing data is simply the same as saying that there are values and information that are unavailable. This could be due to missing files or unavailable information.
A dataset set with missing data means more work for the analyst. There needs to be a transformation in those fields before the dataset can be used.
Generally speaking missing data could lead to bias in the estimation of data.
A data scientist is a data expert who is in charge of data. He performs the job of data extraction, data analysis, data transformation.
