問題 #98
For someone that is not a service administrator to use SQL Developer Web, what package would you need to use to give them access?
答案：A
解題說明：
SQL Developer Web in Autonomous Database relies on Oracle REST Data Services (ORDS) for access. The correct package is:
ORDS_ADMIN.ENABLE_SCHEMA (B): To allow a non-admin user (e.g., ANALYST1) to use SQL Developer Web, the ADMIN user executes ORDS_ADMIN.ENABLE_SCHEMA to enable the schema for ORDS access. This procedure activates the schema for RESTful services, granting privileges like CONNECT and SELECT implicitly for web-based SQL execution. Example:
BEGIN
ORDS_ADMIN.ENABLE_SCHEMA(p_schema => 'ANALYST1');
END;
After this, the user accesses SQL Developer Web via a URL (e.g., https://<adb-host>/ords/analyst1/_sdw), logging in with their database credentials. This is necessary because SQL Developer Web runs on ORDS, and only enabled schemas can interact with it. For instance, an analyst might query SELECT * FROM sales in the web interface post-enablement, without needing full admin rights.
The incorrect options are:
ORDS_ADMIN.GRANT_SCHEMA (A): No such procedure exists in ORDS_ADMIN. Granting is handled via database roles/privileges (e.g., GRANT CONNECT), not a specific ORDS grant function.
ORDS_PRIV.ENABLE_SCHEMA (C): There’s no ORDS_PRIV package; this might confuse with ORDS_ADMIN. The correct package is ORDS_ADMIN for schema enablement.
SQLDEV_ADMIN.GRANT_SCHEMA (D): No SQLDEV_ADMIN package exists. SQL Developer Web access is managed through ORDS, not a separate SQL Developer-specific package.
ORDS_ADMIN.ENABLE_SCHEMA is the standard, secure way to enable non-admin access to this tool in ADB.
問題 #99
Which management operation is correct about Autonomous Databases on Shared Exadata Infrastructure?
答案：B
解題說明：
Management operations for Autonomous Databases on Shared Exadata Infrastructure are limited due to its fully managed nature. The correct statement is:
You cannot configure the scheduling for your Autonomous Databases on Shared Exadata Infrastructure (C): In shared infrastructure, Oracle fully controls maintenance scheduling (e.g., patching, upgrades). Unlike dedicated infrastructure, where users can set maintenance windows, shared ADB users cannot adjust timing. Oracle notifies users of upcoming maintenance (e.g., via email or console), typically in a 7-day window, but the exact schedule is Oracle-driven to optimize the shared Exadata platform. For example, a quarterly patch might occur on a Tuesday at 2 AM UTC, and users must adapt, not reschedule.
The incorrect options are:
You can skip a scheduled maintenance run... (A): False. Shared infrastructure does not allow skipping maintenance runs, even for two quarters. This flexibility exists only in dedicated infrastructure, where users have more control (e.g., skipping up to two consecutive updates). In shared mode, Oracle enforces updates for security and stability across all tenants.
You can perform a "rolling restart"... (B): False. Rolling restarts (restarting nodes sequentially for availability) are not user-initiated in ADB shared infrastructure. Restarts, if needed, are managed by Oracle during maintenance, and users cannot control the process or ensure node-by-node availability.
You can choose to use Release Update or Release Update Revision updates... (D): False. In shared infrastructure, Oracle applies Release Updates (RUs) uniformly across all databases; users cannot choose between RU or Release Update Revisions (RURs), a feature reserved for dedicated deployments.
This reflects the trade-off of shared infrastructure: lower cost and management effort for less control.
問題 #100
Which option describes the connection types that third-party software can use to connect to an Autonomous Database (ADB)?
答案：D
解題說明：
Third-party software can connect to an Autonomous Database using standard Oracle connectivity options. The correct answer is:
Any protocol supported by Oracle Net Services (B): Autonomous Database leverages Oracle Net Services (also known as SQL*Net) for connectivity, supporting protocols like TCP/IP with TLS for secure communication. This allows a wide range of third-party tools (e.g., SQL Developer, Tableau, or custom applications) to connect using established Oracle networking standards.
The incorrect options are:
New ADB-specific protocols (A): There are no proprietary, ADB-specific protocols; it uses Oracle’s existing Net Services framework.
SQL*NET only (C): While SQLNet is part of Oracle Net Services, the broader term “Oracle Net Services” encompasses all supported protocols, not just SQLNet.
JDBC only (D): JDBC is a specific Java-based API for database connectivity, not a protocol, and it’s just one of many ways to connect via Oracle Net Services.
This flexibility ensures compatibility with diverse client applications.
問題 #101
When working with an Autonomous Exadata Infrastructure supporting Autonomous Databases, where do you go to view the maintenance history of the Exadata?
答案：C
解題說明：
Viewing the maintenance history of Autonomous Exadata Infrastructure (AEI) requires navigating the OCI console correctly. The correct path is:
Under Solutions and Platforms then Platform Services then Autonomous Exadata (C): In the OCI console, AEI is categorized under “Solutions and Platforms” (a section for integrated services), then “Platform Services” (covering cloud platform offerings), and finally “Autonomous Exadata.” Here, you select your AEI instance (e.g., by name or OCID), and the details page displays a “Maintenance History” section listing past events (e.g., patching dates, durations, and statuses like “Completed on 2025-03-01”). For example, a quarterly RU applied on January 15 might show “Patch Applied: RU 23.1” with start/end times. This path reflects AEI’s role as a dedicated platform supporting Autonomous Container Databases (ACDs) and Autonomous Databases (ADBs).
The incorrect options are:
Under Core Infrastructure then Compute then Autonomous Exadata (A): “Core Infrastructure” > “Compute” is for virtual machines or bare metal hosts, not Exadata infrastructure. AEI isn’t a compute instance; it’s a database platform.
Under Database then Autonomous Transaction Processing then Autonomous Exadata (B): “Database” > “Autonomous Transaction Processing” focuses on ATP instances, not the underlying Exadata infrastructure. AEI maintenance is separate from specific ADB types.
Under Core Infrastructure then Autonomous Exadata (D): “Core Infrastructure” doesn’t directly list AEI; it’s too broad and lacks the “Platform Services” context needed for Exadata-specific management.
This navigation ensures you access AEI-specific maintenance details efficiently.
問題 #102
Which method does NOT permit you to change the database ADMIN user's password of an Oracle Autonomous Database on Shared Infrastructure?
答案：D
解題說明：
Changing the ADMIN user’s password in an Autonomous Database on Shared Infrastructure is restricted to specific managed methods due to its serverless nature:
Correct Answer (C): “OS command line from the database server” is not permitted because Autonomous Database is fully managed by Oracle. Users do not have direct access to the underlying operating system or server, eliminating this as a viable option.
Valid Methods:
A: The Admin page in the OCI Console allows password changes via the “Change Administrator Password” option, a user-friendly GUI method.
B: The OCI CLI supports password updates using commands like oci db autonomous-database update with the --admin-password parameter.
D: SQL Developer can change the password using an ALTER USER ADMIN IDENTIFIED BY <new_password> command, provided the user has appropriate credentials.
This restriction ensures security and consistency in a managed environment.
