Oracle recommends best practices for effective alarm management:

Correct Answer (A):Suppress alarms during investigationsprevents notification overload while troubleshooting, focusing attention on the issue.

Correct Answer (C):Select the correct alarm interval for your metricensures timely alerts without excessive noise (e.g., 1-minute intervals for critical metrics).

Correct Answer (D):Routinely tune your alarmsadjusts thresholds and settings to match workload changes, maintaining relevance.

Incorrect Option:

Full Detailed In-Depth Explanation:

Service connections in Autonomous Database:

A. DBNAME_LOW:Optimized for high concurrency with minimal resources per query, ideal for many simultaneous queries.

B. DBNAME_MEDIUM:Balanced concurrency and performance.

C. DBNAME_HIGH:Prioritizes individual query performance, not concurrency.

D. DBNAME_CONCURRENT:Not a valid service name.

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.

Securing an Autonomous Database after a user departs involves:

Correct Answer (C): “Rotate the instance wallet and share the new wallet with the remaining users” invalidates the old wallet’s credentials (e.g., certificates in ewallet.p12). Since the wallet secures client connections, rotating it ensures the departed user’s access is revoked, even if they retained a copy.

Incorrect Options:

A: Trusting the user is a security risk, not a solution.

B: Deleting the database user ID doesn’t address wallet-based access if credentials were shared externally.
