<PROGRAM-DESCRIPTION-ANSWER>

A device that operates at a data link layer for transferring the framers between nodes is called as “virtual switch”.

Hence, the correct answer is option “B”.

</PROGRAM-DESCRIPTION-ANSWER>

Explanation of Solution

Virtual switch:

It is a logically defined device that works at the data link layer for passing the frames between the nodes. Such kind of devices is also called as bridge.

  • It enables the VMs to communicate with each other and also with the nodes that reside on physical LAN or WAN.
  • It is possible for a single host to support multiple virtual switches, which in turn is controlled by the hypervisor.

Explanation for incorrect options:

Virtual firewall:

  • Virtual firewall imitates the hardware firewall and is hosted in a virtualized environment. It is the installation of firewall operations in the VM...

Write a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume the list will contain a maximum of 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline. Hints:   - use a for loop to populate the array based on the specified size (the first number entered)              - use a for loop to check first value with last value, second value with second from end, etc.              - if the values do not match, set a Boolean variable to flag which statement to output (yes or no)   Ex: If the input is (remember to include spaces between the numbers): 6 1 5 9 9 5 1 the output is: yes Ex: If the input is: 5 1 2 3 4 5 the output is: C++ coding
