Free Practice Questions for Oracle 1z0-1093-25 Exam

B. Automation of provisioning and management:

Cloud Tooling automates key tasks such asprovisioning, patching, scaling, and maintenance.

Reduces manual configuration errors and saves time.

Ensures consistency in setup and updates, minimizing downtime.

Greatly simplifies lifecycle management, making cloud deployments more efficient than on-premises.

Why the other options are incorrect:

A. More granular hardware control:Cloud tooling abstracts low-level hardware management.

C. No DBA intervention:While reduced, DBAs still handle application-specific configurations and performance tuning.

D. Using older database versions:Exadata Cloud Service supportsonly supported versions, not deprecated ones.

B. Testing patches in a non-production environment:

Critical to ensure that the patch does not introduce performance issues or compatibility problems.

Best Practice:Apply the patch to astaging environmentthat mirrors production, validate stability, and then proceed to production.

Minimizes the risk of unplanned downtime or disruptions.

Why the other options are incorrect:

A. Immediate application in production:Risky as untested patches might cause outages.

C. Automatic patching by OCI:OCI does not automatically apply database patches; the customer must manage this.

D. Patching the standby and failing over:While a good strategy when applicable, it still requires prior testing.

Tagging in Database Management:

Tags in Oracle Cloud Infrastructure are essential fororganizing and managing resources.

Grouping Databases (A):Tags allow databases to be grouped logically, simplifying management and performance analysis.

Filtering and Searching (C):Tags make it easier to find specific databases within theDatabase Management console, improving efficiency in large environments.

Why the other options are incorrect:

B:Tags do not propagate automatically; they must be configured properly.

D:Tags are actively used in Database Management for organizing and filtering.

B. Managing the Oracle Grid Infrastructure software stack:

Customers are responsible for the installation, configuration, and maintenance of the Oracle Grid Infrastructure when using BaseDB VMs.

This includes managing Oracle Clusterware and Automatic Storage Management (ASM) if applicable.

Ensuring the Grid Infrastructure's availability and performance is part of customer-managed tasks.

Why the other options are incorrect:

A. Hardware fault tolerance:Managed by Oracle Cloud Infrastructure.

C. Hypervisor maintenance:Handled by Oracle as part of the OCI infrastructure.

D. Security patching:While OCI provides tools, the responsibility for OS patching lies with the customer.

Database Name (DB Name):

When provisioning aBaseDB VM, thedatabase nameis used to create the initial instance. It specifies how the database will be identified and helps in creating associated system files, such ascontrol files, redo log files, and datafiles. This name is crucial fordatabase instance managementand connectivity within the OCI environment.

The DB name becomes part of theDB System resource identifierin OCI, which is used in automation and management tasks.

Why the other options are incorrect:

A:The hostname is specified independently during network configuration.

B:OS user accounts are configured separately.

D:The character set is chosen during database configuration, not based on the DB name.

Full Backup with bkup_api:

The --full flag in thebkup_api commandensures that the backup includesall datafiles and control files. This command is essential for creating acomplete, consistent backupsuitable for recovery purposes.

The backup is stored inOCI Object Storage, leveraging cloud scalability and redundancy.

The --dbname parameter specifies which database to back up.

Why the other options are incorrect:

A:This command may initiate a default backup, not a full one.

B:Specifying files individually is less efficient than using --full.

D:The --all option does not necessarily imply a full backup.

C. Partitioning and replication of data across multiple nodes:

NoSQL databases typically prioritizehorizontal scalabilityby distributing data across multiple nodes.

Replicationensures data availability even if one node fails.

This approach leads toeventual consistencyrather than strict ACID compliance.

The system can continue to operate despite some nodes being offline, maintaining high availability.

Why the other options are incorrect:

A. Complex joins and transactions:Typical of relational databases prioritizing consistency.

B. Strict referential integrity:More common in SQL databases requiring ACID transactions.

D. Centralized architecture:Opposite of scalable, distributed NoSQL models.

B. Recommendations for parameter tuning:

Database Management analyzes historical performance data and provides tuning recommendations.

These recommendations align with Oracle best practices to optimize database performance.

C. Comparison of parameter settings:

The service allows users to compare parameter configurations between different databases or across time points for a single database.

This is useful for identifying changes or discrepancies that could impact performance.

Why the other options are incorrect:

A. Automatic correction of parameters:Database Management does not automatically correct parameters; changes require manual intervention.

D. Lack of parameter management:Incorrect statement, as the service does offer parameter management features.

SDK Function:

An SDK simplifies database interaction by providing libraries and tools that abstract away the complexities of the underlying API. This allows developers to use familiar programming languages and constructs to interact with the database.

Why the other options are incorrect:

A:Physical storage layout is managed by the database service, not the SDK.

C:Infrastructure management is handled by cloud providers, not the SDK.

D:Network security policies are managed via OCI console or infrastructure tools, not the SDK.
