Oracle 1Z0-1093-25 Exam Dumps

B . Full root access:

Customers have root-level access to manage the OS, install custom software, and configure settings.

This provides flexibility to meet specific application requirements.

D . Responsibility for OS security:

With root access, customers must manage OS security, including updates and patches.

Oracle provides tools to facilitate patching, but the responsibility lies with the customer.

Why the other options are incorrect:

A . Restricted SSH access: SSH access is allowed for VM DB systems.

C . Oracle-managed OS patching: Oracle does not automatically patch the OS; this is a customer responsibility.

E . Initial OS installation by customers: The OS is pre-installed, but ongoing maintenance is customer-driven.

A . Execute ADDM (Automatic Database Diagnostic Monitor) analysis on a historical workload:

Performance Hub allows users to analyze performance data collected over time.

ADDM analysis provides insights into performance bottlenecks and recommendations for tuning.

C . Identify blocking sessions that are impacting database performance:

Performance Hub helps identify active blocking sessions, enabling quick resolution of performance issues.

It provides real-time and historical data for better troubleshooting.

Why the other options are incorrect:

B . Modify database parameters: Performance Hub does not have the ability to change database configurations directly.

D . Upgrade the database: Upgrades are managed through other tools, such as Database Upgrade Assistant (DBUA).

RCU Calculation:

Read Capacity Units (RCUs) are determined based on data size (average record size), read frequency (number of reads per second), and consistency level (eventual vs. strong consistency). Complex security roles do not impact the calculation because they do not directly influence the amount of data read or the frequency of access.

Why the other options are correct:

A: Larger record sizes increase RCU requirements.

B: Higher read frequency demands more RCUs.

D: Strong consistency requires more read operations compared to eventual consistency.

Tagging in Database Management:

Tags in Oracle Cloud Infrastructure are essential for organizing 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 the Database 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 . Automation of provisioning and management:

Cloud Tooling automates key tasks such as provisioning, 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 supports only supported versions, not deprecated ones.
