Answer:
Topology means arrangement of nodes
Explanation:
In computer science the word topology means the arrangement of nodes and elements in a network. For any topology we do need nodes and cables for maintaining the infrastructure.
In mesh topology the all nodes use to get connected by direct link. While each and every node is directly associated with one another. In this infrastructure we do need lot cabling where every node will be connected with one another. While usage of good quality cable in network is also expensive to manage. Although there are lot of benefits of this topology, where the transmission of data would never stop if node is not working the rest will be working to transfer the data among other nodes ,this is more secure because there is no traffic for data to travel via many nodes to reach the destination. Every node is directly connected and communicate. So, once the node is not working the communication will not be stop but the maintenance and troubleshooting will be difficult in this infrastructure.
It is proved along with lot of benefits and network security ,this infrastructure is having some disadvantages as well. Cabling expense , maintenance cost etc . usually small scale networks do not prefer mesh topology. Small scale and low budget companies can not afford this topology because it is expensive.
Although we do believe that the data security is most important for today's era ,so few companies those wanted to keep their information secure and confidential they must use mesh topology by ignoring the cost incurred for this set up. Data security and integrity would never be compromised by some of the companies.
Mesh topology is more safer, more quick infrastructure which is although very expensive , difficult to mange and maintain. Moreover it is overhead of cabling as well to connect every node but the demand of mesh topology would never be less. It is demanding and appealing topology still.
Answer:
A WAN can be one large network or can consist of two or more lans connected together. The Internet is the world's largest wan.
Explanation:
An action which this organization should take to find out if systems have been compromised is: C. Look for unauthorized accounts.
<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 and compromises in the following:
- Operating system
- Web software
- Host device
- Network
This ultimately implies that, a penetration test avails a tester the ability to exploit a weakness and potential security threats on a test network as a privileged user, during vulnerability assessments of the computer system.
In this scenario, we can reasonably infer and logically deduce that an action which this organization or cybersecurity specialist should take to find out if systems have been compromised is to look out for unauthorized accounts.

Answer:
a. tracert
Explanation:
Tracert is a computer network diagnostic demand which displays possible routes for internet protocol network. It also measures transit delays of packets across network. The given output is produced by a tracert command.
Answer: Cell site / Base station
Explanation:
A mobile network also referred to as the cellular network is refered to as the radio network which is distributed over the land areas which are refered to as the cells.
We should note that each is served by at least one fixed-location transceiver, which is called the cell site or the base station.
