350-401 Question 579
Single answerAn enterprise network is experiencing inconsistent network performance across multiple branch offices. Upon investigation, it is determined that branch offices are using different time zones, leading to issues with logs, performance metrics, and scheduled tasks. As a network engineer, which infrastructure service should you implement to ensure a unified time source across all devices in the enterprise network?
- A
Network Time Protocol (NTP)
- B
Quality of Service (QoS)
- C
Simple Network Management Protocol (SNMP)
- D
Domain Name System (DNS)
Show answer and explanation
Correct answer: A
Explanation
NTP (Network Time Protocol) is a critical infrastructure service that synchronizes the clocks of network devices to a common time source, ensuring consistency in timestamps for logs, performance metrics, and scheduled tasks. This resolves the issue of inconsistent time zones across branch offices and ensures accurate analysis and troubleshooting.
- A. Correct.
Correct. NTP ensures all network devices are synchronized to a common time source, which is critical for logs, performance analysis, and task scheduling.
- B. Incorrect.
Incorrect. QoS is used to manage and prioritize network traffic but does not address time synchronization.
- C. Incorrect.
Incorrect. SNMP is used for monitoring and managing network devices, but it does not provide time synchronization.
- D. Incorrect.
Incorrect. DNS is used for translating domain names into IP addresses and does not involve time synchronization.
