1z0-997-22 Exam Question 26

You have been asked to create a mobile application which will be used for submitting orders by users of a popular E-Commerce site. The application is built to work with Autonomous Transaction Processing - Serverless (ATP-S) database as the backend and HTML5 on Oracle Application Express as the front end. During the peak usage of the application you notice that the application response time is very slow. ATP-S database is deployed with 3 CPU cores and 1 TB of memory.
Which two options are expensive or impractical ways to improve the application response times?

A.Scale up CPU core count and memory during peak times.

B.Enable auto scaling for CPU cores on ATP-S database.

C.Identify the maximum memory capacity needed for peak times and scale the memory for the ATP-S database to that number. ATP-S will scale the memory down when not needed.

D.Use the Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application.

E.Identify the maximum CPU capacity needed for peak times and scale the CPU core count for the ATP-S database to that number. ATP-S will scale the CPU core count down when not needed.

You are trying to troubleshoot the configuration of your Oracle Cloud Infrastructure (OCI) Load Balancing service. You have a backend HTTP service for which you have created a backend set in the load balancer. You have configured health checks for the backend set.

B.You are using OCI Domain Name System. You have misconfigured the 'A' record with the wrong IP address leading to requests not getting routed correctly.

C.You are running a TCP-level health check against your HTTP service. The TCP handshake can succeed and indicate that the service is up even when the HTTP service has issues.

D.You are NOT using regional subnets in your Virtual Cloud Network. With Availability Domain (AD) specific subnet. the compute instances of the backend service running in the subnet have issues when the AD is down.
