Exam Associate Cloud Engineer topic 1 question 212 discussion

This is a typical cold start problem. Cold starts happen when a serverless platform like Cloud Run needs to start a new instance to handle a request because no suitable instances are available. This startup time can cause a delay, which is noticeable to users, especially on the first page load.

Both A and D looks good. But going with A as it is worded as some users are impacted during startup, http/2 would help resolve more than what issue is worded here.

Its A. Look at this link: https://cloud.google.com/run/docs/tips/general#optimize_performance You'll see that one of Google's recommendations for improve performance and reduce "cold starts", is to set a minimum of instances.

I checked the google recommendations for cloud run but they never mention HTTP/2. I am going with A

https://cloud.google.com/functions/docs/configuring/min-instances Even though the initial # of instances present in the VM is not stated, setting a min amount of instances "can further help you avoid cold starts and reduce application latency".

min. # of instances should solve latency issue

I chose A too. The question should be related to GCP products and how can you best configure them. I shouldn't be forced to change my app to use HTTP/2

I chosse A notice ''some of user'' and ''initial web page slowly than other page'' because the some of user login the web without load and the cloud run scale the instance to 0 so that the users had to waiting the startup new instance sometimes.

https://www.cloudflare.com/learning/performance/http2-vs-http1.1/ I'm going with D too. B wouldn't help: https://cloud.google.com/run/docs/about-concurrency#concurrency-1 C wouldn't help - setting a max won't increase speed ever. A would not necessarily help - there's no indication that the initial page is taking much longer just because there are too few instances. However, D would improve how things load, as per the first link I posted.

It should be D. HTTP/2 helps to speed up app performance.
