Question-31 : Autoscaling is a feature of Compute Engine that enables VM instances to be added or removed from a managed instance group (MIG) in response to changes in the amount of work being done by the group. Your applications will be able to elegantly manage spikes in traffic thanks to autoscaling, and your costs will be reduced when less resources are required. The game servers used by Mountkirk Games do not automatically scale in the correct manner. They introduced a brand new function about a month ago, and almost overnight, it skyrocketed in popularity. There are a record amount of people attempting to access the service, however a significant portion of those customers are receiving error code 503 and experiencing very poor response times. The HyperText Transfer Protocol, Version 503 Service (HTTP 503) The occurrence of the error response code indicating that the server is unavailable suggests that the server is not prepared to accept the request. The most common reasons for this are an overcrowded server or a server that is offline for maintenance. What should their first line of inquiry be?
A. Determine whether or not the database may be accessed online.
B. Determine whether or not the quota for the project has been met.
C. Confirm that the addition of the new functionality did not result in the introduction of any performance issues.
D. Make sure that the team in charge of load testing is not testing their tool on the production environment.

: 2 Explanation: Option-2 is the correct answer Error code starting like 5xx is something related to server 503 UNAVAILABLE Service unavailable. Typically the server is down. When server is down you will get timeout (503 - service unavailable - not server). Error code starting like 5xx is something related to server 503 UNAVAILABLE Service unavailable. Typically the server is down. 503 has two meaning, Service not available due to server load (slow response) or quota depleted. Not sure Option-2 or C. As per question, slow response, it can be Option-3 or Looking this link, it is B. https://cloud.google.com/appengine/quotas When a resource is depleted When an application consumes all of an allocated resource, the resource becomes unavailable until the quota is replenished. This may mean that your application will not work until the quota is replenished. For resources that are required to initiate a request, when the resource is depleted, App Engine by default returns an HTTP 403 or 503 error code for the request instead of calling a request handler. This behavior applies to the Instance hours resource. Option-2 In the unlikely event that your API request fails, you'll receive an HTTP status code response. A status code of 403 has error information about incorrect input and an HTTP status code of 503 has error information indicating which API quotas have been exceeded. These responses allow your custom application to detect these errors and take appropriate action.
