Oracle Cloud Database Services 2025 Professional Sample Questions (Q51-Q56):

NEW QUESTION # 51
Which two metrics are available for monitoring within the Performance Hub's Real-Time SQL Monitoring feature in Database Management?

  • A. Database Version
  • B. Number of CPUs on the host
  • C. Physical Reads
  • D. Average Active Sessions

Answer: C,D

Explanation:
Performance Hub Real-Time SQL Monitoring:
ThePerformance Hubin Oracle Database Management provides detailed real-time monitoring of SQL queries, including:
* Physical Reads (A):Measures the number of physical I/O operations performed by a SQL statement.
* Average Active Sessions (B):Reflects the number of sessions actively performing database operations, giving insights into workload and bottlenecks.
These metrics help database administratorsanalyze query performanceand detect issues in real-time.
Why the other options are incorrect:
* C:Number of CPUs is a hardware metric, not part of SQL monitoring.
* D:Database version is static information, not a performance metric.


NEW QUESTION # 52
Within an IAM policy for Oracle NoSQL Database Cloud Service, what is the purpose of the "resource" element when defining table access permissions?

  • A. To define the specific NoSQL table or tables to which the policy's permissions apply.
  • B. To specify the IAM group that the policy applies to.
  • C. To set the expiration date for the IAM policy.
  • D. To determine the geographical region where the NoSQL database is located.

Answer: A

Explanation:
B: Define specific NoSQL table permissions:
* The"resource"element specifies which Oracle NoSQL tables the IAM policy will apply to.
* It allows fine-grained access control by linking specific tables to permission statements.
* This ensures that only authorized users or groups can perform operations on specified tables.
Example IAM Policy Syntax:
{
"action": "nosql:table:read",
"resource": "ocid1.nosqltable.oc1..exampleuniqueID",
"effect": "allow"
}
Why the other options are incorrect:
* A. Specify IAM group:Groups are defined in the"subject"element, not the "resource" element.
* C. Geographical region:The region is usually part of theOCID(Oracle Cloud Identifier), not directly specified in the resource element.
* D. Set expiration date:Expiry is not defined within the "resource" element.


NEW QUESTION # 53
Oracle NoSQL Database Cloud Service supports operations on data based on keys. Which of the following best describes how data is primarily accessed and retrieved within this model?

  • A. Data is accessed using structured query language (SQL) with joins and complex filtering conditions.
  • B. Data is primarily accessed using the unique key associated with the desired data item.
  • C. Data is searched based on the content of the values using full-text indexing and complex search queries.
  • D. Data is accessed through a predefined schema that dictates how data is organized and queried.
  • E. Data is retrieved by traversing relationships between interconnected nodes in a graph structure.

Answer: B

Explanation:
C: Accessing data using the unique key:
* Oracle NoSQL Database Cloud Service follows akey-value data model.
* Data is accessed directly using aunique key, which is highly efficient for lookups.
* The value associated with the key can be simple or complex (e.g., JSON objects).
* Provides fast read and write operations.
Why the other options are incorrect:
* A. SQL with joins:Typical of relational databases, not NoSQL.
* B. Graph traversal:Relevant to graph databases, not key-value stores.
* D. Full-text indexing:Not the primary access method in key-value databases.
* E. Predefined schema:NoSQL databases generally supportschema-lessdata storage.


NEW QUESTION # 54
Which of the following components is responsible for automatically offloading suitable queries from MySQL to the HeatWave accelerator?

  • A. MySQL Shell
  • B. Oracle Cloud Infrastructure (OCI) Load Balancer
  • C. MySQL Query Optimizer
  • D. HeatWave AutoPilot
  • E. MySQL Router

Answer: C

Explanation:
A: MySQL Query Optimizer:
* TheMySQL Query Optimizerdetermines whether a query can benefit from HeatWave's in-memory, columnar processing.
* If a query is deemed suitable, it is automatically offloaded to the HeatWave cluster.
* This process significantly improves the execution speed of complex analytical queries.
Why the other options are incorrect:
* B. HeatWave AutoPilot:Manages workload optimization but does not directly offload queries.
* C. MySQL Router:Manages connection routing, not query offloading.
* D. MySQL Shell:Primarily used for administrative tasks, not query optimization.
* E. OCI Load Balancer:Manages network traffic distribution, unrelated to database query processing.


NEW QUESTION # 55
Which statement accurately reflects the impact of applying an Oracle-provided patch to the operating system on an Exadata Database Service instance using the Oracle Cloud Infrastructure (OCI) console?

  • A. The OCI console-initiated patch process updates the database software and the OS, allowing for a rolling update strategy on the database nodes, minimizing downtime. Storage nodes are updated separately.
  • B. The OCI console-initiated patch process only patches the storage servers; database nodes require manual OS patching.
  • C. The OCI console-initiated patch process automatically updates both the database software and the underlying operating system on all compute and storage nodes concurrently.
  • D. The OCI console-initiated patch process only updates the database software, leaving the underlying OS untouched.

Answer: A

Explanation:
OCI Patching Process:
The Oracle Cloud Infrastructure console simplifies the patching process by integrating bothdatabase software and OS patching. Therolling update strategyensures that one node at a time is patched, reducing the downtime associated with updating the entire cluster. The storage nodes are updated in a separate process to ensure data integrity and availability.
Why the other options are incorrect:
* A:The OCI console updates both the OS and database software.
* B:Updates are performed in a rolling fashion, not concurrently.
* D:The OCI console handles OS patching for both compute and storage nodes.
