NEW QUESTION # 84
You have provisioned an Exadata VM Cluster on Exascale Infrastructure with 8 ECPUs per VM and a 300 GB Exascale Database Storage Vault. Your workload has grown and additional compute capacity is now required. What should you do?
Answer: A
Explanation:
Elastic resource allocation is a fundamental design characteristic of Oracle Exadata Database Service on Exascale Infrastructure . A VM requires a minimum of 8 enabled ECPUs at initial provisioning, but its compute allocation can subsequently be increased in 4-ECPU increments .
Oracle's Exascale architecture draws compute resources from Oracle-managed shared infrastructure rather than requiring the customer to purchase or provision dedicated database servers. This permits a customer to start with a relatively small footprint and increase capacity as workload requirements develop.
The workload therefore does not need to be migrated to Dedicated Infrastructure merely because additional processing power is required. Nor is it necessary to destroy and rebuild the VM Cluster or create an entirely new Exadata Infrastructure resource. Exascale is specifically intended to avoid those fixed-capacity operational patterns.
Oracle additionally supports online scaling of Exascale storage independently through the associated Database Storage Vault, reinforcing the service's elastic consumption model.
Therefore, D is correct.

NEW QUESTION # 85
Which Recovery Manager (RMAN) method is recommended by Oracle Maximum Availability Architecture (MAA) and used by Zero Downtime Migration (ZDM) when direct data transfer is enabled?
Answer: A
Explanation:
For ZDM physical online migrations using direct data transfer , Oracle's Maximum Availability Architecture pattern uses RMAN's Restore From Service capability. Rather than first creating backup pieces in a staging location, transporting them, and then restoring them on the target, RMAN restores the target database directly across the network from the source service.
This design reduces intermediate storage requirements and simplifies the migration pipeline. Once the target database has been instantiated, ZDM automatically configures Oracle Data Guard and uses redo transport to maintain synchronization until the planned switchover. The combination of Restore From Service and Data Guard is the central technical pattern Oracle documents for physical online migration to Exadata Database Service on Oracle AI Database@Azure.
Although DUPLICATE ... FROM ACTIVE DATABASE is a legitimate RMAN cloning capability in other contexts, it is not the named method documented for this ZDM direct-data-transfer workflow. Compressed backup-set streaming and incremental image-copy pushing also imply different backup/staging mechanisms.
Therefore, Restore From Service is the MAA-aligned RMAN method represented by the scenario.

NEW QUESTION # 86
You are provisioning a new Oracle Autonomous AI Database Serverless instance in the Azure Portal and must configure the database credentials under the Configuration tab. What is the database administrator username for this instance, and how is it configured in the creation wizard?
Answer: B
Explanation:
When Oracle Autonomous AI Database Serverless is provisioned through Oracle AI Database@Azure, the administrative database account follows the standard Autonomous Database account model. The Azure creation workflow exposes the Username field as read-only and set to ADMIN .
The administrator therefore supplies the password for the predefined ADMIN account but does not choose or rename the account during database creation. Oracle currently specifies password requirements separately, including minimum and maximum length and character-composition requirements.
The account is not derived from the Microsoft Entra ID identity that deploys the Azure resource. Azure RBAC and Microsoft Entra authentication govern access to the Azure resource-management plane, whereas the ADMIN credential is a database-level account. Similarly, SYS is not presented as the configurable provisioning username for Autonomous AI Database Serverless, and the username is not generated from subscription metadata.
This separation between Azure control-plane identity and Oracle database credentials is architecturally important when designing authentication and administrative access.
Therefore, the correct answer is A .

NEW QUESTION # 87
You attempted to register a new migration job in Zero Downtime Migration (ZDM) to migrate to Oracle Database@Azure, but the command fails because an active or failed migration job is already registered for that source database. What action must you take in the ZDM CLI to clear the existing registration and allow the new job to be configured?
Answer: C
Explanation:
ZDM manages migrations as persistent scheduled jobs and assigns each job a unique job ID. Administrators must manipulate these jobs through the supported ZDMCLI lifecycle commands rather than modifying ZDM repository or log files manually.
Oracle documents the command zdmcli abort job -jobid < job_id > for terminating a specified ZDM job.
When an existing job context is preventing a new migration workflow from being established for the same source, the supported administrative approach among the available options is to identify the existing job and abort it through ZDMCLI.
Restarting the ZDM service does not remove the persistent job record; the job metadata is maintained by ZDM rather than existing only in the running daemon's memory. Manually deleting files from ZDM directories is unsupported and risks corrupting or desynchronizing job state. Likewise, the proposed -ignore ALL option is not a supported mechanism for bypassing ZDM's migration-job lifecycle controls.
Consequently, B is the correct operational command because it acts on the existing migration through the supported ZDM control interface.

NEW QUESTION # 88
Which network port must be open and tested to ensure SQL*Net connectivity between the source database and the ZDM Service Host during a ZDM Physical Online migration to Exadata on Oracle Database@Azure?
Answer: B
Explanation:
The standard Oracle listener and SQL Net port used in the documented ZDM Physical Online migration workflow is TCP 1521 . Oracle's Oracle AI Database@Azure ZDM migration procedure explicitly instructs administrators to test SQL Net connectivity by running tnsping between source and target database hosts using port 1521.
This connectivity is required because ZDM and its underlying migration technologies must establish database- level communication for prechecks, configuration, target instantiation, Data Guard configuration, synchronization, and migration orchestration. If the source or target listener has been intentionally configured to use a nondefault port, that configured listener port must be permitted instead.
Port 22 is used for SSH administration between the ZDM Service Host and managed hosts. Port 443 is associated with HTTPS-based cloud service and API communication. Port 2049 is conventionally associated with NFS and is relevant when migration workflows use NFS-based staging, but it is not SQL*Net.
Therefore, D. 1521 is the correct answer.
