Discuss HP HPE7-A07 Exam Topic 6 Question 41

in a WLAN network with a tunneled SSID. you see the following events in HPE Aruba Networking Central:

The customer asks you to investigate log messages What should you tell them?

AThis indicates a security issue. The client with a MAC address ending with 37 18;0d Is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network.

BThis is normal, expected behavior. No further actions are needed.
C. This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18
:Od. You should upgrade the client WLAN driver.

DThere is a roaming issue Enable Fast Roaming 802.11r and OKC to resolve the issue.

Suggested Answer: B

The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.

I feel B is the safest bet. No need to panic.

Tracey 6 months ago

I’d go with A. Better safe than sorry, right?

Tashia 7 months ago

D is interesting. Roaming problems can cause confusion.

Chaya 7 months ago

I lean towards C. Driver issues happen often.

Hyun 7 months ago

But B seems more likely. It could just be normal behavior.

Annelle 7 months ago

I think option A sounds serious. Denial-of-Service is no joke.

Casey 7 months ago

This is pretty normal behavior, no need to panic.

Maryann 7 months ago

Wait, a DoS attack? That’s surprising! Are we sure?

Micaela 8 months ago

Definitely a roaming issue, enabling 802.11r makes sense.

Aliza 8 months ago

Wait, is this a trick question? I bet the answer is "B) This is normal, expected behavior. No further actions are needed."

Lorrine 8 months ago

Sounds like a roaming problem. Enabling Fast Roaming and OKC should do the trick.

Daren 9 months ago

Hmm, could be a driver issue. Might want to try upgrading the client's WLAN driver.

Nancey 9 months ago

Nah, this is just normal behavior. No need to worry about it.

Glenn 9 months ago

This looks like a classic case of a DoS attack. We need to take action immediately!

Gilma 9 months ago

I feel like option A might be too extreme. A Denial-of-Service attack seems unlikely without more evidence.

Alisha 9 months ago

I recall practicing a question about roaming issues before. Option D seems plausible, especially if the client is having connectivity problems.

James 9 months ago

I'm not too sure, but I remember something about driver issues being common. Maybe option C could be the answer?

Stephaine 10 months ago

I'm a bit confused by the different options here. I'll need to carefully review the log messages and network events to determine the root cause before making any recommendations to the customer.

Marylou 10 months ago

This seems like a common WLAN issue that I've encountered before. I think the solution might be to enable Fast Roaming and OKC, as suggested in option D. I'll double-check the details, but that's my initial thought.

Ricki 10 months ago

Okay, let's see here. The client MAC address ending in 37:18:0d is a bit suspicious, but I don't want to jump to conclusions. I'll need to gather more information before making any recommendations.

Keena 10 months ago

I think option B sounds right since I've seen similar scenarios where those log messages are just normal behavior in tunneled SSIDs.

Stevie 10 months ago

Sounds like a driver issue to me. Upgrading could help!

Louis 11 months ago

I disagree, this looks more like a security concern.

Edison 11 months ago

Haha, I bet the client with the MAC address ending in 37:18:0d is just trying to get a free Wi-Fi connection. Gotta love those hackers!

Olene 11 months ago

The log messages seem to indicate a potential security issue, but I'm not sure if that's the right conclusion. I'll need to research more about tunneled SSIDs and WLAN behavior to make an informed decision.

Bettye 11 months ago

Hmm, this looks like a tricky one. I'll need to carefully analyze the log messages and the network events to determine the best course of action.

We should definitely analyze those logs first.

Lavonda 6 months ago

What if it’s a roaming problem?

Trina 6 months ago

↳ replying to Bettye

I lean towards the driver issue.

Mitzie 6 months ago

↳ replying to Bettye

Could be, but it might also be normal behavior.

Shaquana 10 months ago

↳ replying to Bettye

I think it might be a security issue.
