John is working as a network administrator in his organization. A user is unable to connect to the network. All other users on that switch are able to connect successfully to the network. Which of the following could be a probable cause of this issue?

C)Switching loop is occurring on the switch
D)Misconfigured port on the switch

Question

Quizplus · Accepted Answer

Only one user on the network is facing this issue, so it can be concluded that the network is fine. This issue is associated with a part of the network that is related to the affected user only.
Key Takeaway: Of the options given here, if a DNS server issue, subnet issue, or switching loop issue occurs, the entire network would be affected. Hence, a port on the switch must be misconfigured, a cable is unplugged or otherwise shorted out, or the NIC on the computer is misconfigured, has a corrupt driver, or is faulty.
