Answer:

Round-Robin DNS

Explanation:

According to my experience in Information Technology and Networking it can be said that based on the information provided the best solution would be to set up a Round-Robin DNS. This term refers to a technique used to balance the load on a server, where a client request is sent to each server one at a time, and then the system repeats the process from the top of the request list. This prevents the server from being drowned in a sea of simultaneous requests.

Which statement is true? Select 3 options.
irina1246 [14]

Answer:

The statements which are true are;

  • A user-defined data type can include other user-defined data types
  • A user-defined data type is defined using a class
  • A user-defined data type can include a list

Explanation:

A user-defined data type (UDT) is a datatype that is defined and derived by the use of the datatypes which preexist including existing user-defined datatypes and the built-in datatypes

It is therefore true that a user-defined data type can include other user-defined data types

A class is a user-defined data type that contains both its member data and member functions, that can be used when an instance of the class is first created

Therefore, a user-defined data type is defined using a class

In a user-defined data type, a variable has actual data within it which can include an array or list

Therefore a user-defined data type can include a list.

kondor19780726 [428]

The Network Mapper (Nmap) commands that would be useful on this test network are:

  1. nmap xxx.xxx.x.x -p
  2. nmap xxx.xxx.x.x -A

<h3>What is a penetration test?</h3>

A penetration test can be defined as a cybersecurity technique that simulates a cyber attack against an end user's computer system, so as to scan, identify, test and check for exploitable vulnerabilities in the following:

  • Operating system
  • Web software
  • Host device
  • Network

This ultimately implies that, a penetration test avails an tester the ability to exploit a weakness and potential security threats on a test network as a privileged user, during vulnerability assessments of the system.

<h3>The Network Mapper (Nmap) commands.</h3>

In this scenario, the Network Mapper (Nmap) commands that would be useful on this test network are:

  1. nmap xxx.xxx.x.x -p
  2. nmap xxx.xxx.x.x -A
