1Z0-1195-25 Exam Questions & Answers

'Oracle Exadata Cloud Service' (B) offers expanded flexibility with shared or dedicated Exadata infrastructure, allowing customers to choose between cost-effective shared resources or isolated dedicated hardware for performance and compliance needs. 'Oracle Database Cloud Service' (A) is VM-based and lacks Exadata's hardware integration, 'Oracle Autonomous Database' (C) is fully managed without hardware choice, and 'Oracle Exalogic Cloud Service' (D) is an outdated middleware platform, not database-focused. Oracle's documentation highlights Exadata Cloud Service's deployment options.

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.

'Exadata' integrates software and hardware and is available both 'In the Oracle Cloud and customer site' (D). It is offered as Exadata Cloud Service (public cloud) and Exadata Cloud@Customer (on-premises), providing flexibility for hybrid deployments. 'Only in a hybrid cloud' (A) is too restrictive, 'Only in public cloud environments' (B) ignores Cloud@Customer, and 'Only at the customer site' (C) excludes the cloud option. Oracle's documentation confirms Exadata's availability in both OCI and on-premises configurations.

The Oracle-recommended way to upgrade databases is 'AutoUpgrade' (D). AutoUpgrade automates the upgrade process, handling pre-checks, upgrades, and post-upgrade tasks with minimal manual intervention, reducing errors and downtime. 'Database Upgrade Assistant (DBUA)' (A) is a GUI tool but less automated, 'Data Pump Export/Import' (B) is for data migration, not direct upgrades, and 'Command Line Upgrade' (C) is manual and error-prone. Oracle's official upgrade guides endorse AutoUpgrade for its efficiency and reliability.

For 'Exadata Cloud@Customer' without Bring Your Own License (BYOL), 'Oracle Native Network Encryption and TDE (Transparent Data Encryption)' (D) are implemented out-of-the-box. Native Network Encryption secures data in transit, while TDE encrypts data at rest, both enabled by default to ensure baseline security compliance. 'Oracle Key Vault' (A), 'Audit Vault and Database Firewall' (B), and 'Database Vault and Data Masking Pack' (C) are advanced security options requiring additional configuration or licensing, not automatically included without BYOL. Oracle's Exadata Cloud@Customer documentation confirms these encryption features as standard.
