Complete Question:
Let's say that you handle the IT systems administration for your company. There's a server inside of your organization that checks how often client machines access it. If a client machine hasn't accessed the server in three months, the server won't allow the client machine to access its resources anymore. What can you set to make sure that your client machines and the server times are in sync?
Answer:
Network Time Protocol (NTP).
Explanation:
As the IT systems administrator, you can set the network time protocol (NTP) to make sure that your client machines and the server times are in synchronization.
A network time protocol (NTP) can be defined as an internet standard protocol which is used by an IT system administrator to synchronize a computer's clock to a particular time reference over packet switched or local area network (LAN) and variable-latency data networks. NTP was developed at the University of Delaware by Professor David L. Mills.
<em>Basically, the network time protocol uses the coordinated universal time (UTC) and a client-server model to measure the total round-trip delay for a computer process. </em>
Answer:
Data remanence
Explanation:
Data remanence is the retention of erased data on a magnetic medium. Sensitive detection systems can pick up the residue (remnants) from previously recorded data even though the area has been rewritten.
This is not a simple procedure; however, it is employed if the <u>missing information</u> is related to national defense or some other critical situation
Answer:
Logical Network Diagrams.
Explanation:
Network Diagrams is the visual diagram that represents the networking of telecommunications and computer. <u>There are two types of network diagrams- Physical and Logical.</u>
Logical Network Diagram represents the information that flows through a network. The diagrams shown in the logical network diagram are routers and firewalls, VLAN Ids, IP address, traffic flow, etc. Logical Network Diagram is helpful in troubleshooting.
<u>Logical Network Diagram helps in determining whether a network has VLAN for public assessing or not</u>.
So, the correct answer is the Logical Network Diagram.
