Important Oracle 1Z0-1195-25 Exam Questions

Answer: D

Explanation:

For migrating 'old database backups' to OCI, 'Archive Storage' (D) is the most cost-effective service. Archive Storage offers the lowest cost per gigabyte for long-term, infrequently accessed data, ideal for backups that don't require immediate retrieval. 'Object Storage (standard)' (A) is more expensive and suited for frequent access, 'Block Volume' (B) is high-performance and costly, and 'File Storage' (C) is for active file systems. Oracle's storage pricing and use case documentation recommend Archive Storage for cost-effective backup archival.

Answer: B, C

Explanation:

'Oracle SQLcl' (SQL Developer Command Line) is a lightweight, command-line interface for interacting with Oracle Databases. It has two key characteristics: 'Tracks database schema changes' (B), through integration with tools like Liquibase, allowing DBAs to monitor and manage schema evolution; and 'Ability to execute SQL batch files' (C), enabling automation of multiple SQL statements in scripts. 'Creates isolated development environments' (A) is not a feature of SQLcl, as it's a client tool, not a virtualization platform. 'Available in the OCI Cloud Shell by default' (D) is incorrect, as OCI Cloud Shell provides a general terminal but does not pre-install SQLcl. Oracle's SQLcl documentation confirms these capabilities.

Answer: A, D

Explanation:

The 'Autonomous JSON Database' is 'Accessed via document APIs' (A), such as SODA, for NoSQL-style operations, and offers 'Instant auto-scaling' (D) for compute and storage with no downtime. 'Applications cannot be built without SQL' (B) is false, as document APIs suffice, and 'A DBA is required' (C) is incorrect due to its self-managing nature. Oracle's documentation highlights these autonomous and API-driven features.

Answer: B

Explanation:

'Compartments' (B) in Oracle Cloud Infrastructure (OCI) allow you to logically group and isolate resources for organization, access control, and billing. 'Identity and Access Management Groups' (A) organize users, not resources. 'Tenancy' (C) is the root container for all resources, not a grouping mechanism, and 'Availability Domain' (D) is a physical data center division, not a logical grouping tool. Oracle's OCI documentation identifies Compartments as the primary feature for resource isolation and management.

Answer: B, C

Explanation:

The 'OCI Data Catalog' has two true characteristics: 'Harvest object storage to derive schemas' (B), as it scans OCI Object Storage to extract metadata and schemas, and 'Discover data using powerful search' (C), offering robust search capabilities for data discovery. 'Management is required' (A) is vague and not a defining trait, and 'Data Catalog does not integrate with Autonomous Database' (D) is false, as it integrates seamlessly for metadata management. Oracle's documentation confirms these features.
