NEW QUESTION # 105
How do you change the tablespace quota for user MTHEO on an Autonomous Database on Shared Infrastructure?
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
In Autonomous Database on Shared Infrastructure, tablespace quotas are managed using standard SQL commands, as administrative packages like DBMS_CLOUD_ADMIN are restricted in this environment. The correct method is:
ALTER USER MTHEO QUOTA UNLIMITED ON TABLESPACE DATA: This command directly modifies the user’s quota on the DATA tablespace, which is the default tablespace in Autonomous Database. “UNLIMITED” removes any storage restrictions.
Analysis of options:
A: Incorrect. DBMS_CLOUD_ADMIN is used in dedicated infrastructure for advanced administrative tasks, not shared infrastructure for quota changes.
B: Correct. This is the standard SQL syntax supported in shared infrastructure.
C: Incorrect. ALTER TABLESPACE modifies tablespace properties, not user quotas, and isn’t applicable here.
D: Incorrect. ALTER DATABASE syntax is invalid for user quotas; it’s for database-wide settings.
NEW QUESTION # 106
Where can a user's public SSH key be added on the Oracle Cloud Infrastructure Console in order to execute API calls?
Answer: C
Explanation:
SSH keys in OCI are used for secure access, but their role in API calls needs clarification. The correct answer is:
Navigate to Identity, select Users panel on the console and select "Add Public Key" (D): This is the correct process, but with a caveat—it’s about API authentication, not SSH for API calls per se. In OCI, API calls are authenticated using API keys (RSA key pairs), not SSH keys directly. To enable API access for a user, you generate a public/private key pair (e.g., using openssl), then add the public key in the OCI console:
Go to “Identity & Security” > “Users.” Select the user (e.g., john.doe).
Under “API Keys,” click “Add API Key.”
Upload the public key (e.g., ~/.oci/oci_api_key_public.pem).
This associates the key with the user, allowing API calls (e.g., oci db autonomous-database list) authenticated via the private key and config file (e.g., ~/.oci/config). The question’s phrasing (“SSH key”) likely misuses terminology, intending “API key,” as SSH keys are for compute instance access, not APIs. For example, a user might add a key to call the ADB API, securing requests with a signature.
The incorrect options are:
On the Autonomous Database Console (A): The ADB console manages database-specific settings (e.g., wallets), not user API keys, which are handled at the tenancy level under Identity.
SSH keys are not required in Oracle Cloud Infrastructure (B): False in general—SSH keys are needed for compute instances—but misleading here, as API calls use API keys, not SSH keys. Authentication (e.g., via tokens or keys) is required for APIs.
SSH keys cannot be added from console. They have to be added using REST APIs only (C): False. The console supports adding API keys under the Users panel; REST APIs (e.g., CreateApiKey) are an alternative, not the only method.
The correct path reflects OCI’s user management for API access, despite the SSH terminology confusion.
NEW QUESTION # 107
Which two statements apply to the Autonomous Database service on Dedicated Infrastructure? (Choose two.)
Answer: A,B
Explanation:
Autonomous Database on Dedicated Infrastructure offers more control than shared infrastructure. The two correct statements are:
You, as the customer, are responsible for all patching operations (A): In dedicated infrastructure, customers manage patching for Autonomous Container Databases (ACDs) and Autonomous Databases (ADBs), unlike shared infrastructure where Oracle handles it. You choose when to apply Release Updates (RUs) or skip them (up to two quarters), using the OCI console or API (e.g., oci db autonomous-container-database update). For example, you might schedule an RU for an ACD on a Saturday night, downloading the patch from Oracle and applying it manually to minimize downtime. This responsibility comes with the dedicated model’s flexibility.
You can set maintenance windows for each individual Autonomous Container Database (C): Dedicated infrastructure allows setting specific maintenance windows per ACD, not just at the Exadata Infrastructure level. In the OCI console, under each ACD’s details, you configure a preferred time (e.g., “Sundays, 02:00-04:00 UTC”), ensuring patches or upgrades align with your schedule. For instance, ACD1 might patch Sundays, while ACD2 patches Tuesdays, tailoring downtime to different workloads.
The incorrect options are:
You can set maintenance windows for an Autonomous Exadata Infrastructure (B): Maintenance windows are set at the ACD level, not the broader Autonomous Exadata Infrastructure (AEI) level. AEI maintenance (e.g., hardware updates) is Oracle-managed, with notification but no customer scheduling.
Patching occurs on the first Sunday of each quarter (D): There’s no fixed schedule like “first Sunday.” In dedicated mode, you control patching timing within a quarter, notified by Oracle of available RUs, unlike shared infrastructure’s Oracle-driven schedule.
These statements highlight dedicated infrastructure’s customer-driven management.
NEW QUESTION # 108
Which two license types does the customer need to benefit from BYOL when leveraging on-premise Enterprise Database licenses in Oracle Autonomous Database?
Answer: A,B
Explanation:
Full Detailed In-Depth Explanation:
Bring Your Own License (BYOL) allows using existing on-premises Oracle licenses in the cloud:
A: False. Exadata is included in Autonomous Database; no separate license is needed.
B: False. Active Data Guard is an optional feature, not required for BYOL.
C: True. RAC is needed for BYOL when scaling beyond 16 OCPUs, as Autonomous Database uses RAC for high availability in larger deployments.
D: True. Multitenant is mandatory, as Autonomous Database uses a multitenant architecture (CDB/PDB).
E: False. TDE is included by default, not a BYOL requirement.
NEW QUESTION # 109
A customer wants to increase the throughput of their inserts. They have discovered that the bottleneck is in the storage I/Os of their environment. What should they do to remove this bottleneck?
Answer: B
Explanation:
Addressing a storage I/O bottleneck for insert throughput in Autonomous Database involves resource adjustments:
Correct Answer (C): “Increase the number of OCPUs allocated to the database” boosts processing power, which directly improves I/O performance. In Autonomous Database, OCPUs handle both compute and I/O operations; more OCPUs increase the I/O bandwidth, reducing the bottleneck for insert-heavy workloads.
Incorrect Options:
A: Removing non-JSON data may optimize storage use but doesn’t directly address I/O throughput for inserts.
B: “Noisy neighbors” is a shared infrastructure concern, but migration isn’t a standard solution for I/O bottlenecks and requires Oracle intervention, not user control.
D: There is no DBMS_CLOUD.INCREASE_THROUGHPUT procedure; this is a fabricated option.
Scaling OCPUs is the most effective user-controlled solution.
