350-401 Question 210
Select 3A network administrator is troubleshooting a connectivity issue between two routers on different subnets. The administrator can ping the local interface on Router A but cannot ping the remote interface on Router B. Which tools would be most effective to identify the root cause of this issue?
- A
Traceroute
- B
Ping
- C
Conditional Debugs
- D
SNMP
- E
Syslog
Show answer and explanation
Correct answers: A, B, E
Explanation
To diagnose the connectivity issue, tools like traceroute and ping are essential for identifying the path and verifying reachability between routers. Syslog can provide additional insights into any errors or events occurring on the routers. While conditional debugs and SNMP are useful in other scenarios, they are not the most effective tools for resolving this specific connectivity issue.
- A. Correct.
Traceroute is an effective tool for identifying where a network failure occurs by mapping the path packets take to the destination. It would help the administrator determine if the issue lies in the path between the routers.
- B. Correct.
Ping can be used to verify basic connectivity and determine whether packets are being delivered. In this case, pinging the remote interface can confirm whether Router B is reachable.
- C. Incorrect.
Conditional debugs are more specific and used for detailed troubleshooting of certain conditions or scenarios, such as protocol issues. However, they are not typically used for basic connectivity issues like this one.
- D. Incorrect.
SNMP is a network management tool used for monitoring and managing network devices. It is not typically used for real-time troubleshooting of connectivity issues.
- E. Correct.
Syslog can provide logs of events and errors occurring on the devices. In this scenario, it can help identify if Router B is logging any issues related to the connectivity problem.
