Discuss Cisco 300-410 Exam Topic 14 Question 94

Refer to the exhibit.

An engineer is troubleshooting BGP on a device but discovers that the clock on the device does not correspond to the time stamp of the log entries. Which action ensures consistency between the two times?

AConfigure the service timestamps log uptime command in global configuration mode.

BConfigure the logging clock synchronize command in global configuration mode.

CConfigure the service timestamps log datetime localtime command in global configuration mode.

DMake sure that the clock on the device is synchronized with an NTP server.

Suggested Answer: A

In OSPF (Open Shortest Path First), the MTU (Maximum Transmission Unit) size must match on both sides of a link for OSPF neighbors to form an adjacency12.If the MTU sizes do not match, the OSPF adjacency will not form, and the routers will not become neighbors12.

In this case, R1 cannot establish a neighbor relationship with R2.One possible reason for this could be a mismatch in the MTU size on the interfaces of R1 and R212.

To resolve this issue, you can configure themtu ignorecommand on the interfaces of R1 and R2 (Option A).This command allows OSPF to ignore the MTU size when determining if it can form an adjacency with a neighbor12.This means that even if the MTU sizes do not match, OSPF will still form an adjacency, and R1 and R2 will become neighbors12.

I disagree, the logging clock synchronize command seems more relevant here.

Geoffrey 11 months ago

Wait, is it really that simple? I thought it was more complicated.

Aracelis 11 months ago

I thought configuring service timestamps would work too?

Shantell 11 months ago

Definitely option D! That's the best way to ensure accurate timestamps.

Nana 12 months ago

You need to sync the clock with an NTP server.

I vaguely recall something about the logging clock synchronize command, but I can't remember if that was for this exact scenario. Could it be option B?

Mollie 1 year ago

I think we practiced a question similar to this, and it was about ensuring the clock was synced. I want to say option D again, but I could be mixing it up.

Leana 1 year ago

I'm not entirely sure, but I feel like we covered something about configuring timestamps in the logs. Maybe option C?

Annamae 1 year ago

I remember discussing the importance of NTP for time synchronization in our study group, so I think option D might be the right choice.

Hassie 1 year ago

I'm a little confused by this question. The options all seem to be about configuring logging, but the question is asking about the device clock. I'll have to think this through carefully to make sure I understand what the right solution is.

Leah 1 year ago

Okay, I think I've got this. The key is to synchronize the device clock with an NTP server, which is option D. That way, the log timestamps will match the actual time on the device.

Lucia 1 year ago

This seems like a straightforward configuration issue. I'll carefully read through the options and think about which one would ensure the log timestamps match the device clock.

Alisha 1 year ago

Hmm, I'm a bit unsure about this one. The question is asking about ensuring consistency between the log timestamps and the device clock, but I'm not sure which of these commands would be the best solution.

Trinidad 1 year ago

Okay, I think I've got it. The key is that we need to export only the products that are assigned to the site catalog, not the full master catalog. I'm leaning towards option C or D.

Wait, the device has a clock? I thought we were just supposed to wing it and hope the logs make sense!

User1: That's right, we need to make sure the clock is accurate for troubleshooting.

User3: D) Make sure that the clock on the device is synchronized with an NTP server.

↳ replying to Vincenza

User2: So, what's the best way to ensure consistency between the device clock and log entries?

Kristofer 1 year ago

↳ replying to Vincenza

User1: Yeah, the device has a clock that needs to be synchronized.

Xuan 1 year ago

Ah, the good old 'is the clock right?' troubleshooting step. Can't go wrong with a trusty NTP server!

Denise 1 year ago

This question is a real head-scratcher! I'm just going to guess and hope for the best. *rolls dice*

Viola 1 year ago

I'm not sure why the other options wouldn't work. Doesn't the service timestamps log command also help with time consistency?

Krystina 1 year ago

↳ replying to Viola

C) Configure the service timestamps log datetime localtime command in global configuration mode.

Stephaine 1 year ago

↳ replying to Viola

B) Configure the logging clock synchronize command in global configuration mode.

A) Configure the service timestamps log uptime command in global configuration mode.

Option D is the right choice. Synchronizing the device clock with an NTP server ensures that the log entries match the actual time on the device.

A) Configure the service timestamps log uptime command in global configuration mode.

Jillian 2 years ago

I'm not sure, but configuring the service timestamps log datetime localtime command also sounds like a good option.

Alonso 2 years ago

I agree with Corinne, syncing the clock with an NTP server should fix the issue.

Corinne 2 years ago

I think the answer is D.
