F5 Networks 301a Exam - Topic 2 Question 116 Discussion

An HA pair of LTM devices that load balance multiple HTTPS applications utilizes highly customized RAM Cache and compression profiles on each virtual server. The LTM Specialist who is administering the HA pair regularly observes entines in the log similar to the following:tmm tmm I708S1 011e0002.4. sweeper_update: aggressive mode activated (117504/138240 pages)No DoS attacks arc occurring. No user problems have been reported. Which step should the LTM Specialist take to help mitigate the issue?
B) change the Adaptive Reaping Low watermark
A) change the Adaptive Reaping High watermark
C) allocate less memory to the RAM cache feature
D) use a OneConnect profile

Why not just allocate less memory to the RAM cache? Seems like an easy fix.

Wait, aggressive mode activated? Is that normal? Sounds concerning!

I disagree, using a OneConnect profile might be overkill for this situation.

I recall that using a OneConnect profile can optimize connections, but I’m not convinced it directly addresses the sweeper_update message we’re seeing here.

I feel like allocating less memory to the RAM cache might be a solution, but I’m not sure if that would actually resolve the aggressive mode issue.

This seems similar to a practice question we did about memory management. I think changing the High watermark could help, but I’m not completely confident.

I remember discussing the Adaptive Reaping settings in class, but I'm not entirely sure which watermark to adjust for this situation.

Ah, I see what's going on here. The LTM is running low on memory, so the "aggressive mode" is kicking in to try and free up some space. Reducing the RAM cache size, as option C recommends, should help resolve the issue without impacting the applications. Solid choice.

Based on the information provided, it seems like the RAM cache is the likely culprit. Reducing the cache size, as option C suggests, seems like the most straightforward way to mitigate the memory pressure. I'll go with that.

Whoa, this is a tough one. I'm a bit confused by the different options - I'm not sure if changing the watermarks or using a OneConnect profile would really address the memory pressure issue. I'll have to think this through more carefully.

Okay, the log entry indicates the LTM is in "aggressive mode" due to memory pressure. I'm thinking reducing the RAM cache size might help, so I'll go with option C.

Hmm, this seems like a tricky one. I'll need to carefully review the log entry and think through the potential causes before deciding on the best approach.

Hold up, aren't we supposed to optimize performance? Reducing the cache size might not be the best idea. Maybe we should try adjusting the watermarks instead, like in options A and B.

The log entry indicates that the RAM cache is hitting its high watermark, so reducing the cache size seems like the logical step to take. Option C looks good to me.
