200-301 Question 29
Single answerA company has deployed a server in its network to host applications for its employees. The server is experiencing performance issues during peak hours. As a network administrator, what could be the most likely cause of the performance degradation?
- A
Insufficient CPU and memory resources allocated to the server
- B
High latency caused by an outdated routing protocol on the network
- C
Improper DNS configuration affecting the server's hostname resolution
- D
A physical cable disconnection between the server and the switch
Show answer and explanation
Correct answer: A
Explanation
The most likely cause of performance degradation in a server during peak hours is insufficient CPU and memory resources. During high demand, the server may not have enough resources to handle all incoming requests, resulting in slower response times and degraded performance. Other options, such as routing protocols or DNS issues, do not directly correlate with the described scenario of performance problems during peak usage.
- A. Correct.
Servers experiencing performance issues during peak hours are often limited by their CPU and memory resources. If these resources are insufficient, the server cannot handle the workload effectively.
- B. Incorrect.
High latency caused by an outdated routing protocol is unlikely to directly cause server performance degradation unless it affects the server's ability to communicate with other devices, which is not specifically mentioned in the scenario.
- C. Incorrect.
Improper DNS configuration typically affects hostname resolution but does not directly cause performance issues on a server. It is more likely to cause connectivity problems.
- D. Incorrect.
A physical cable disconnection would result in complete loss of connectivity, not performance degradation during peak hours.
