1Z0-931-25 practice question 17 of 25

A customer wants to increase the throughput of their inserts. They have discovered that the bottleneck is in the storage I/Os of their environment. What should they do to remove this bottleneck?

Full set: 149 questions
Answer options
A: Remove any non-JSON data from the database.
B: Ask Support to migrate their setup to a node without noisy neighbors.
C: Increase the number of OCPUs allocated to the database. Correct answer
D: Run the DBMS_CLOUD.INCREASE_THROUGHPUT procedure.
Correct Answer:
C. Increase the number of OCPUs allocated to the database.
Explanation

In Oracle Autonomous Database (ADB), compute (OCPU) and I/O resources are bundled together. Scaling the number of OCPUs allocated to the database instance directly and proportionally increases the available I/O throughput, memory, and concurrent session limits. Since the identified bottleneck is storage I/O during inserts, increasing the OCPU count is the designated and most effective method for a user to increase the I/O capacity and thereby improve insert throughput.

Why Incorrect

A. Removing non-JSON data is irrelevant to the underlying storage I/O capacity. The bottleneck is with physical throughput, not the logical data format being inserted.
B. ADB's architecture is designed to provide consistent performance and mitigate "noisy neighbor" issues. The primary user-controlled method for scaling performance is adjusting OCPUs, not requesting a migration.
D. The DBMSCLOUD.INCREASETHROUGHPUT procedure does not exist. The DBMSCLOUD package is used for operations related to object storage and other cloud services, not for scaling database resources.

Autonomous Database: In the section on managing resources

it states: "When you change the OCPU count

the I/O bandwidth and memory allocated to your database changes in proportion to the OCPU count." This directly supports that increasing OCPUs increases I/O throughput.

Autonomous Database: The documentation on predefined database services shows how different services (HIGH

MEDIUM

LOW) have different concurrency and I/O shares

but the absolute I/O capacity for all services is determined by the database's OCPU count.

DBMSCLOUD Package: The official documentation for the DBMSCLOUD package lists all available subprograms. A procedure named INCREASETHROUGHPUT is not included

confirming it is a fictitious option.
