Actual exam question for Adobe's AD0-E134 exam

Question #: 2
Topic #: 2

A customer who is running an AEM application on premise reports that the application is slowing down over time and even crashes The issues seem to start occurring after a new production deployment. The AEM developer knows that the described symptoms could be caused by a memory leak.

Which two steps should be taken after confirming the problem is related to a memory issue? (Choose two.)

AOpen the error log and look for messages with 'OutOfMemoryError'

BCreate a heap dump for analysis

CAnalyze the request log and make sure the number of requests are below the expected threshold

DIncrease the cache ratio of the application

ECreate a thread dump for analysis

Show Suggested Answer

Suggested Answer: B, E

Creating a heap dump and a thread dump are two steps that should be taken after confirming the problem is related to a memory issue. A heap dump is a snapshot of the memory usage of the Java Virtual Machine (JVM) at a given point in time. A heap dump can be used to identify memory leaks, memory consumption patterns, and objects that occupy large amounts of memory. A thread dump is a snapshot of the state of all threads that are part of the JVM process. A thread dump can be used to identify deadlocks, blocked threads, and CPU-intensive threads.

Not sure if a thread dump is necessary, though.

Wait, can increasing the cache ratio really help with memory leaks?

Definitely check the error log for 'OutOfMemoryError'.

Increasing the cache ratio seems like a workaround rather than a solution to the memory leak. I think we should stick to the analysis steps first.

I feel like analyzing the request log might be relevant too, but it doesn't directly address the memory issue. Should we focus on the heap dump instead?

I'm a bit unsure, but I think creating a heap dump for analysis is also crucial. We did a practice question on that, right?

I remember we discussed how important it is to check the error logs for 'OutOfMemoryError' messages. That seems like a logical first step.

I'm pretty sure a foreign key maps to a primary key, so I'll go with option A.

I think the key here is to focus on the XMLDB configuration and the XQuery expression itself. Those seem like the most likely areas to optimize the response time. The other options seem a bit tangential.

Okay, I've got this. The phases are Pre-certification, Certification, Authorization, and Post-Authorization. I'm confident I can get this one right.
