Refer to the exhibit. Shortly after SiteA was connected to SiteB over a new single-mode fiber path, users at SiteA report intermittent connectivity issues with applications hosted at SiteB. What is the cause of the intermittent connectivity issue?

A. Interface errors are incrementing.
B. High usage is causing high latency.
C. An incorrect SFP media type was used at SiteA.
D. The sites were connected with the wrong cable type.

Correct Answer: A

Explanation:

Explanation:
The only indicator of any issues here is the reliability 166/255 on SiteA. When the input and output errors increase, they affect the reliability counter. This indicates how likely it is that a packet can be delivered or received successfully. Reliability is calculated like this: reliability = number of packets / number of total frames.
The value of 255 is the highest value meaning that the interface is very reliable at the moment. The calculation above is done every 5 minutes.

Under which condition is TCP preferred over UDP?

A. UDP is used when low latency is optimal, and TCP is used when latency is tolerable.
B. TCP is used when dropped data is more acceptable, and UDP is used when data is accepted out-of-order.
C. TCP is used when data reliability is critical, and UDP is used when missing packets are acceptable.
D. UDP is used when data is highly interactive, and TCP is used when data is time-sensitive.
