[All AD0-E117 Questions]

AEM Site users report that the web content pages render very slowly. An Architect notices that the CPU usages of the AEM Publish instances are spiking and reviews the following entry in the log:

[Frt Nov 27 23:11:00 2019] [I] [pid 16004 (tid 140134145820416)] Current cache hit ratio: 47.94 %

What should the Architect do to increase the dispatcher cache ratio and prevent the AEM Publish CPU usage spikes?

Show Suggested Answer Hide Answer
Suggested Answer: A

According to Adobe Experience Manager documentation5, dispatcher is a caching and load balancing tool that can be used to improve performance and security of AEM sites.Dispatcher cache configuration can be adjusted using various properties in the dispatcher.any file6. Creating a cron job that will delete the dispatcher cache on a regular basis is not a good idea as it will reduce the cache hit ratio and increase the load on AEM servers.

I’m surprised the cache hit ratio is so low, thought it would be better!

Wait, deleting the cache regularly? That sounds counterproductive!

Adding more servers (D) might help, but it’s not a long-term fix.

Adding more dispatcher servers could distribute the load better, but I wonder if that’s really addressing the root cause. I’m leaning towards A, but I’m not completely confident.

I think we went over a similar question where deleting the cache regularly was mentioned. But creating a cron job feels risky; it might not really help with the cache hit ratio.

I'm not entirely sure, but adding more AEM instances might help with the CPU spikes. That sounds like B, but I feel like it could just be a temporary fix.

I remember we discussed the importance of optimizing the Dispatcher cache configuration in class. It seems like A could be the right choice.
