100-150 Question 234
Select 4A network administrator needs to monitor and collect data from multiple routers in the network to analyze performance metrics and troubleshoot issues. Which methods can the administrator use to access and collect data about these devices?
- A
Use SNMP (Simple Network Management Protocol) to retrieve data from the routers.
- B
Log in to the routers using SSH and manually check their status.
- C
Configure the routers to send syslog messages to a centralized server.
- D
Ping the routers periodically to gather detailed performance metrics.
- E
Enable NetFlow or similar flow-based monitoring tools on the routers.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To access and collect data about network devices, administrators can use a combination of tools and protocols. SNMP, SSH, syslog, and flow-based monitoring tools like NetFlow are all effective methods for gathering comprehensive information about device performance and status. Ping, while useful for basic connectivity checks, does not provide sufficient detail for in-depth monitoring or troubleshooting.
- A. Correct.
SNMP is a widely used protocol to monitor and manage network devices. It allows the collection of performance data, device statuses, and more.
- B. Correct.
SSH provides secure remote access to a router's CLI, where an administrator can check configurations, logs, and device status manually.
- C. Correct.
Syslog allows devices to send log messages to a centralized server, which can be used to monitor and analyze network events.
- D. Incorrect.
Ping is useful for checking connectivity but does not provide detailed performance metrics about a device.
- E. Correct.
NetFlow or similar flow-based tools can be enabled to collect data about traffic patterns and network utilization from routers.
