NEW QUESTION # 107
Which two statements are correct about Autonomous Data Warehouse on Shared Exadata Infrastructure?
Answer: A,D
Explanation:
Let’s evaluate each statement about Autonomous Data Warehouse (ADW) on Shared Exadata Infrastructure:
A . Oracle Database Result Cache is enabled by default for all SQL statements: True. ADW enables the Result Cache by default to improve query performance by storing frequently accessed results in memory.
B . You have direct access to the database node: False. ADW is a fully managed service; users do not have direct access to underlying nodes, which Oracle manages for patching, scaling, and security.
C . Parallelism is not enabled by default: False. Parallelism is enabled by default in ADW to optimize large analytical queries across multiple CPUs.
D . Compression is enabled by default. Autonomous Data Warehouse uses Hybrid Columnar Compression for all tables by default: True. Hybrid Columnar Compression (HCC) is applied automatically to reduce storage and enhance query performance.
Thus, A and D are correct, reflecting ADW’s default performance optimizations.
NEW QUESTION # 108
Which statement is true when the Autonomous Database has auto scaling enabled?
Answer: B
Explanation:
When auto scaling is enabled in Oracle Autonomous Database, it dynamically adjusts resources to handle workload demands. The correct answer is:
Enables the database to use up to 3x CPU/IO resources immediately when needed by the workload (D): Auto scaling allows the database to automatically scale its CPU and I/O resources up to three times the base number of OCPUs provisioned, without manual intervention. This ensures the database can handle sudden spikes in demand efficiently, reverting to the base level when the workload decreases. This feature applies to both Autonomous Transaction Processing (ATP) and Autonomous Data Warehouse (ADW).
The incorrect options are:
Increases the number of sessions available to the database (A): Auto scaling does not directly increase session limits; session capacity is tied to the service level (e.g., LOW, MEDIUM, HIGH) and not dynamically adjusted by auto scaling.
Scales the PGA and SGA size when needed for the workload (B): The Program Global Area (PGA) and System Global Area (SGA) are memory structures managed automatically by Oracle, but auto scaling specifically adjusts CPU and I/O resources, not memory allocation directly.
Database concurrency is scaled up when needed by the workload (C): While increased CPU/IO resources can improve concurrency indirectly, auto scaling does not explicitly manage concurrency levels; this is more related to connection service settings.
This capability enhances performance elasticity for unpredictable workloads.
NEW QUESTION # 109
Which statement is correct about the Service Console in an Autonomous Database?
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
The Service Console is a database-specific management interface:
A: False. Auto-scaling is managed via the OCI Console, not the Service Console.
B: True. The Service Console allows monitoring and terminating runaway SQL statements that consume excessive resources.
C: False. Manual backups are created through OCI Console or SQL commands, not the Service Console.
D: False. Moving compartments is an OCI Console function, not a Service Console task.
NEW QUESTION # 110
How can an Autonomous Database resource be provisioned without logging into the Oracle Cloud Infrastructure Console?
Answer: A
Explanation:
Provisioning an Autonomous Database without using the OCI Console is possible through programmatic methods. The correct answer is:
Using the cloud infrastructure command line interface or REST API calls (D): The Oracle Cloud Infrastructure Command Line Interface (OCI CLI) and REST APIs allow users to provision and manage Autonomous Database resources programmatically. This method is ideal for automation or when GUI access is not preferred. For example, the OCI CLI command oci db autonomous-database create can be used to provision a database by specifying parameters like compartment ID, database name, and workload type. Similarly, a REST API POST request to /autonomousDatabases achieves the same result.
The incorrect options are:
Using the DBCA on the database server (A): The Database Configuration Assistant (DBCA) is a tool for on-premises Oracle databases, not for cloud-based Autonomous Databases, which are fully managed by Oracle.
Connecting to the cloud infrastructure console using the SSH wallet (B): SSH wallets are for secure shell access to compute instances, not for provisioning databases or interacting with the OCI Console.
It cannot be done (C): This is false, as programmatic provisioning via CLI or API is explicitly supported.
This capability enhances automation and integration into DevOps workflows.
NEW QUESTION # 111
What are two differentiators of Oracle Autonomous Database on Dedicated Infrastructure? (Choose two.)
Answer: C,D
Explanation:
Autonomous Database on Dedicated Infrastructure offers unique features:
Correct Answer (A): “Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level” highlights dedicated hardware (compute, storage, network), ensuring isolation and performance not available in shared setups.
Correct Answer (E): “Users have more control over the maintenance schedule” allows scheduling maintenance windows, unlike shared infrastructure’s fixed schedules.
Incorrect Options:
B: OS customization is not allowed; Oracle manages the stack fully.
C: No OS access is provided; it’s a managed service.
D: SYS privileges are not unique to dedicated infrastructure; they depend on user roles, not deployment type.
These differentiators enhance control and isolation for enterprise needs.
