Question 1
Question Type: MultipleChoice

Which component aids in assessing the readiness of a MySQL instance for migration to MySQL
HeatWave, specifically identifying potential compatibility issues?

Options:
A- MySQL Enterprise Monitor
B- Oracle SQL Developer
C- MySQL Shell Upgrade Checker Utility
D- Oracle Cloud Advisor
E- MySQL Workbench

Answer:
C

Explanation:
C . MySQL Shell Upgrade Checker Utility:

The utility analyzes MySQL instances for compatibility with newer versions, such as MySQL 8.0
used by HeatWave.

It checks for:

Syntax differences

Data type mismatches

Deprecated features

The tool outputs a report highlighting issues that may impact migration to HeatWave.

Why the other options are incorrect:

A . MySQL Enterprise Monitor: Focuses on monitoring performance, not compatibility.

B . Oracle SQL Developer: Primarily used for database development, not upgrade checks.

D . Oracle Cloud Advisor: Provides cloud optimization recommendations, not MySQL compatibility
checks.

E . MySQL Workbench: A visual tool for database design and administration, not specifically for
 Explore Oracle 1Z0-1093-25 Questions By Morrow - Page 3

upgrade assessment.

Question 2
Question Type: MultipleChoice

Which of the following is a proactive strategy to avoid encountering table rate limits in Oracle
NoSQL Database Cloud Service?

Options:
A- Regularly increasing the table's storage capacity to accommodate future growth.
B- Carefully designing the table schema and indexes to optimize query performance and
minimize the number of read/write operations required.
C- Disabling data encryption to reduce the overhead of read/write operations.
D- Consolidating all data into a single large table to simplify management.

Answer:
B

Explanation:
B . Optimizing schema and indexes:

Efficient schema design reduces the number of read/write operations.

Proper indexing reduces the need to scan large data volumes, minimizing the number of read
capacity units (RCUs) consumed.

This proactive approach helps stay within the provisioned rate limits, avoiding throttling.

Why the other options are incorrect:

A . Increasing storage capacity: Does not address the rate of operations, only storage volume.

C . Disabling encryption: Unwise due to security risks and does not significantly impact rate
limits.

D . Consolidating data into one table: Likely increases the rate of operations, worsening the
problem.

Question 3
Question Type: MultipleChoice

Which two statements are accurate regarding the placement of VM Clusters within an Exadata
Cloud Infrastructure?

Options:
A- Only one VM Cluster can exist within an Exadata Cloud Infrastructure.
B- Multiple VM Clusters can be created within a single Exadata Cloud Infrastructure, allowing for
workload isolation.
C- VM Clusters can span multiple Exadata Cloud Infrastructures, providing a single, unified
database environment.
D- Each VM Cluster must be associated with its own dedicated VCN, isolating network traffic
between clusters.
E- VM Clusters within the same Exadata Infrastructure can share a single VCN, simplifying
network management.

Answer:
B, E

Explanation:
B . Multiple VM Clusters within a single Exadata Infrastructure:

Multiple clusters can coexist, each isolated for specific workloads.

Supports resource optimization and isolation.

E . Sharing a single VCN:

VM Clusters within the same Exadata Infrastructure can be configured to use the same Virtual
Cloud Network (VCN), streamlining network management.

Why the other options are incorrect:

A . Only one VM Cluster: Incorrect as multiple clusters are supported.

C . Spanning multiple infrastructures: VM Clusters do not span Exadata Infrastructures; they are
confined to a single infrastructure.
 Explore Oracle 1Z0-1093-25 Questions By Morrow - Page 5

D . Dedicated VCN for each cluster: Unnecessary, as clusters can share a VCN.

Question 4
Question Type: MultipleChoice

Which BaseDB lifecycle management activity is MOST directly associated with ensuring the
continued availability of a database instance during a planned maintenance window?

Options:
A- Taking a full database backup using RMAN.
B- Performing an in-place upgrade of the database software.
C- Using Oracle Data Guard for a switchover operation.
D- Applying a quarterly security patch.
E- Resizing the block volume storage.

Answer:
C

Explanation:
C . Using Oracle Data Guard for a switchover operation:

A switchover is a planned role reversal between the primary and standby databases.

Zero data loss: Since both databases are synchronized, it minimizes downtime.

Ideal for planned maintenance: The primary database is switched to the standby, allowing
maintenance on the original primary without downtime.

Data Guard Switchover:

sql

CopyEdit

ALTER DATABASE SWITCHOVER TO standby_db;

Why the other options are incorrect:

 Explore Oracle 1Z0-1093-25 Questions By Morrow - Page 6

A . Full backup with RMAN: Backup does not ensure availability during maintenance.

B . In-place upgrade: Typically involves downtime.

D . Quarterly patch: Patching often requires database restarts, causing downtime.

E . Resizing block volume: Does not maintain availability if the database requires restarting.
