NEW QUESTION # 142
While provisioning a dedicated Autonomous Container Database, which backup retention period CANNOT be implemented?
Answer: B
Explanation:
Full Detailed In-Depth Explanation:
When provisioning an Autonomous Container Database (ACD) on dedicated infrastructure, Oracle provides specific options for backup retention periods to balance data recovery needs with storage costs. According to the official Oracle documentation, the available backup retention periods for a dedicated ACD are:
7 days: This is the default retention period for a newly provisioned ACD.
15 days: An option for extended retention beyond the default.
60 days: The maximum supported retention period for ACDs, offering the longest recovery window.
The option of 120 days is not supported as a backup retention period for an Autonomous Container Database. This limitation is due to the design of the Autonomous Database service, which caps retention at 60 days to optimize storage and performance on dedicated Exadata infrastructure. Attempting to set a retention period beyond 60 days is not an available choice during provisioning. Users must select a retention period that meets their recovery point objectives (RPO) within these constraints, noting that longer retention increases storage usage and associated costs.
NEW QUESTION # 143
Which can be used to ensure that your Autonomous Database is accessible only from a given set of IPs?
Answer: C
Explanation:
Restricting access to an Autonomous Database to specific IPs involves network security controls. The correct answer is:
Access Control List (C): In Autonomous Database, an Access Control List (ACL) defines which IP addresses or CIDR blocks (e.g., 192.168.1.0/24) can connect to the database. You configure this via the OCI console under the ADB’s “Access Control List” settings, adding rules like “Allow TCP from 10.0.0.0/16 on port 1522.” This applies to public endpoints (shared infrastructure) or private endpoints with additional network rules, ensuring only authorized IPs can initiate connections. For example, a company might restrict access to its office VPN range, blocking all other traffic. ACLs work at the database level, complementing VCN security.
The incorrect options are:
Security List (A): Security Lists operate at the VCN subnet level, controlling traffic to all resources in the subnet (e.g., ingress TCP 1522 to an ADB subnet). While useful, they’re broader than ADB-specific ACLs, which target the database instance directly, making ACLs the precise answer here.
IP Vault (B): There’s no “IP Vault” in OCI. This might confuse OCI Vault (for secrets), but it doesn’t manage IP access.
IPSec List (D): IPSec secures traffic via VPNs, not IP allowlisting for database access. It’s unrelated to ADB connectivity restrictions.
ACLs provide a database-specific, user-friendly way to enforce IP-based access control.
NEW QUESTION # 144
Which four levels of access can be defined in policies? (Choose four.)
Answer: A,B,C,E
Explanation:
Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) defines four verb levels for policy permissions:
Read (B): Allows viewing resource details without modification (e.g., read autonomous-databases).
Manage (C): Permits full control, including creating, updating, and deleting resources (e.g., manage autonomous-databases).
Inspect (D): Enables listing resources and basic metadata without detailed access (e.g., inspect autonomous-databases).
Use (E): Allows interaction with resources (e.g., connecting to a database) without altering their configuration.
Incorrect Option:
Create (A): “Create” is not a standalone verb; it’s part of the manage verb, which includes creation, update, and deletion actions.
These levels provide granular control over resource access in OCI.
NEW QUESTION # 145
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.
NEW QUESTION # 146
You created an Autonomous Database without auto scaling. Which two ways can you enable auto scaling? (Choose two.)
Answer: B,D
Explanation:
Enabling auto scaling on an existing Autonomous Database can be done without unnecessary complexity:
Correct Answer (A): “Click Scale Up/Down and select the Auto Scaling checkbox” is the simplest GUI method. In the OCI Console, navigate to the database, select “Scale Up/Down,” and enable the auto scaling option, allowing up to 3x the base OCPUs dynamically.
Correct Answer (C): “Use a REST call to enable Auto Scaling” leverages the OCI REST API to update the database configuration with the isAutoScalingEnabled parameter set to true. This is ideal for programmatic control.
Incorrect Options:
B: Shutting down the instance is unnecessary; auto scaling can be enabled while the database is running.
D: Multiple REST calls, including shutdown and restart, overcomplicate the process when a single API call suffices.
These methods ensure minimal disruption and efficient resource management.
