NEW QUESTION # 82
Which command should you issue to enable application continuity on Oracle Autonomous Database on Shared Infrastructure?
Answer: C
Explanation:
Application Continuity ensures seamless failover for applications:
Correct Answer (B): EXEC DBMS_CLOUD_ADMIN.ENABLE_APP_CONT('<service_name>'); is the correct command for Autonomous Database on Shared Infrastructure. It enables Application Continuity for a specific service (e.g., tpurgent), leveraging the DBMS_CLOUD_ADMIN package designed for cloud-specific administration.
Incorrect Options:
A: ALTER SESSION only affects the current session, not persistent database-wide settings.
C, D: ALTER DATABASE and ALTER SYSTEM are not supported in Autonomous Database’s managed environment; Oracle restricts such commands.
This ensures application resilience in a managed setup.
NEW QUESTION # 83
Which three Oracle Cloud Infrastructure (OCI) resources do you need to configure before provisioning your Autonomous Database with a private endpoint? (Choose three.)
Answer: A,D,E
Explanation:
Provisioning an Autonomous Database with a private endpoint requires:
Correct Answer (A): Network Security Group (NSG) defines traffic rules for the private endpoint, restricting access to specific sources.
Correct Answer (B): VCN (Virtual Cloud Network) provides the network foundation, hosting the subnet and endpoint.
Correct Answer (E): Subnet (private) contains the database’s private endpoint, isolating it from public access.
Incorrect Options:
C: Security Lists apply to subnets but are optional with NSGs, which are preferred for finer control.
D: Route Table is needed for connectivity (e.g., to a NAT Gateway), but not strictly required for the private endpoint itself.
These ensure secure, private access.
NEW QUESTION # 84
A new Python developer has joined your team and needs to access the Autonomous Database dat a. How does the developer connect to and interact with the Autonomous Database from Python?
Answer: B
Explanation:
Python developers connect to Autonomous Database using a dedicated library:
Correct Answer (D): “By using Oracle Client and the cx_Oracle interface” (now renamed oracledb) is the recommended method. The Oracle Client provides the underlying connectivity, and cx_Oracle (or oracledb) is a Python module for database access, supporting wallet-based authentication to Autonomous Database.
Incorrect Options:
A: SQL Developer is a GUI tool, not a Python interface.
B: DBD-oracle is not a standard Python library for Oracle; it’s likely a typo or confusion with Perl’s DBI.
C: JDBC is for Java, not Python; it’s incompatible without a bridge like JPype.
This method ensures efficient, secure Python integration.
NEW QUESTION # 85
Which three methods can be used to migrate your existing Oracle database to Autonomous Database? (Choose three.)
Answer: A,D,E
Explanation:
Migrating to Autonomous Database requires robust tools:
Correct Answer (B): Oracle Zero Downtime Migration (ZDM) minimizes downtime by synchronizing data and schema changes while the source remains online, ideal for critical systems.
Correct Answer (C): GoldenGate provides real-time replication, enabling near-zero downtime migration by continuously syncing data to Autonomous Database.
Correct Answer (D): Data Pump exports data and schema to dump files, which are then imported into Autonomous Database, suitable for offline migrations.
Incorrect Options:
A: SFTP with CSV files is not a comprehensive migration method; it lacks schema migration and automation for complex databases.
E: RMAN is for backup/restore, not optimized for full migrations to Autonomous Database’s managed environment.
These methods cater to different migration needs (online vs. offline).
NEW QUESTION # 86
Which vaults are used for storing customer-managed encryption keys for Autonomous Database on Dedicated Infrastructure?
Answer: A
Explanation:
Autonomous Database on Dedicated Infrastructure supports customer-managed encryption (CME) keys for enhanced security control. The correct vaults are:
Oracle Key Vault, Oracle Cloud Infrastructure Vault (D):
Oracle Key Vault (OKV): A centralized key management solution designed for Oracle environments, OKV securely stores and manages encryption keys. It integrates with Autonomous Database to provide customer-managed TDE (Transparent Data Encryption) keys, offering features like key rotation and auditing. For example, a DBA might upload a master encryption key to OKV, which the database then uses to encrypt data at rest.
Oracle Cloud Infrastructure Vault (OCI Vault): OCI Vault is a general-purpose secrets management service in OCI, capable of storing encryption keys, passwords, and other sensitive data. It supports storing TDE keys for Autonomous Database, providing a cloud-native option with high availability and scalability. You might store a key in OCI Vault and link it to your database via the OCI console.
The incorrect options are:
Oracle Audit Vault, Oracle Key Vault (A): Oracle Audit Vault is for audit log management and analysis, not key storage. It doesn’t support CME for Autonomous Database.
Oracle Cloud Infrastructure Vault, Oracle Database Vault (B): Oracle Database Vault enforces access controls within the database but isn’t a key storage vault; it’s about privilege management, not key management.
Oracle Database Vault, Oracle Key Vault (C): As above, Database Vault isn’t a key storage solution, making this pairing incorrect.
Both OKV and OCI Vault offer robust security for CME, giving customers flexibility based on their infrastructure preferences (on-premises OKV vs. cloud-based OCI Vault).
