104. Frage
For someone that is not a service administrator to use SQL Developer Web, what package would you need to use to give them access?
Antwort: C
Begründung:
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.
105. Frage
Which three options do NOT change when enabling auto scaling? (Choose three.)
Antwort: A,B,C
Begründung:
When enabling auto scaling in an Oracle Autonomous Database, the feature dynamically adjusts resources based on workload demand, but certain configuration elements remain unchanged unless manually altered.
Amount of storage (A): Auto scaling focuses on adjusting CPU and I/O resources to meet performance needs. The storage allocation remains constant because it is a separately provisioned resource that requires manual adjustment via the OCI Console or API. This ensures that storage capacity is not inadvertently reduced or expanded without explicit user intent.
Parallelism settings (B): These settings determine how many parallel processes are used for query execution. Auto scaling does not modify this pre-defined configuration; it adjusts resource usage (e.g., CPU cores) without altering the parallelism framework established for the database.
Level of concurrency (E): Concurrency refers to the maximum number of simultaneous user sessions. While auto scaling can indirectly influence concurrency by adjusting available resources, the concurrency limit itself is a fixed setting that remains unchanged unless explicitly modified by the administrator.
Incorrect Options:
I/O resources (C): Auto scaling directly impacts I/O resources by increasing or decreasing them alongside CPU adjustments to handle workload fluctuations.
Number of OCPUs displayed in the console (D): While the base OCPU count remains static, the effective number of OCPUs in use (up to three times the base) changes dynamically with auto scaling, and this is reflected in the console, making this option subject to change.
This behavior ensures that auto scaling optimizes performance without disrupting foundational database configurations.
106. Frage
What is a best practice when planning and instituting access controls for your Autonomous Dedicated environment regarding subnets, compartments, and user groups?
Antwort: A
Begründung:
When designing access controls for an Autonomous Dedicated environment, Oracle recommends redundancy and separation for security and manageability:
Correct Answer (D): “Create at least 2 of each resource” (subnets, compartments, user groups) is a best practice:
Subnets: Using at least two subnets (e.g., one public, one private) enhances security by segregating traffic and provides failover options if one subnet encounters issues.
Compartments: Multiple compartments allow logical separation (e.g., dev, test, prod), simplifying access control and resource management.
User Groups: At least two groups (e.g., admins, developers) streamline permission assignments and reduce the risk of over-privileging users.
Incorrect Options:
A: OCI allows multiple subnets and compartments; restricting to one limits flexibility and security.
B: There’s no such limitation; multiple resources are supported and encouraged.
C: A VCN with only public subnets contradicts security best practices, as private subnets are critical for database isolation.
This approach aligns with Oracle’s guidance for secure and scalable deployments.
107. Frage
When you are increasing the number of OCPUs in your Autonomous Database, what does its status show?
Antwort: A
Begründung:
Scaling OCPUs in an Autonomous Database triggers a specific status update. The correct answer is:
SCALING IN PROGRESS (D): When you increase (or decrease) the number of OCPUs, the database status in the OCI console changes to “SCALING IN PROGRESS.” This indicates that the system is actively adjusting the compute resources, a process that typically completes in a few minutes with no downtime for active transactions.
The incorrect options are:
UPSCALE IN PROGRESS (A): “Upscale” is not an official status term used by Oracle for this operation.
RESIZING IN PROGRESS (B): While “resizing” might intuitively fit, Oracle specifically uses “SCALING IN PROGRESS” for CPU adjustments.
UPLIFT IN PROGRESS (C): “Uplift” is not a recognized status in the context of Autonomous Database scaling.
This status reflects Oracle’s terminology for dynamic scaling.
108. Frage
Data Guard is enabled for your Autonomous Database and the Lifecycle State field for the primary database indicates that it is Stopped. Which statement is true?
Antwort: D
Begründung:
With Autonomous Data Guard enabled, the primary and standby databases are tightly coupled:
Correct Answer (C): “Standby database is also stopped” is true. When the primary database is stopped (e.g., via OCI Console), the standby database is also stopped to maintain consistency and alignment between the two. This ensures the standby remains a viable replica when the primary restarts.
Incorrect Options:
A: Switchover (role reversal) requires manual initiation and an active primary; it doesn’t occur automatically on stop.
B: The standby is not terminated; it remains configured but stopped.
D: Failover (standby promotion) is not automatic on a planned stop; it’s triggered only by primary failure.
This behavior preserves Data Guard functionality.
