Oracle Cloud Database Services 2025 Professional - 1z0-1093-25 Free Exam Questions

A. To provide a secure communication channel between the Database Management Service and the database.

B. To automate database patching and upgrades.

C. To manage the underlying operating system of the Compute instance.

D. To handle database backups and recovery operations.

A. Regularly increasing the table's storage capacity to accommodate future growth.

B. Disabling data encryption to reduce the overhead of read/write operations.

C. Carefully designing the table schema and indexes to optimize query performance and minimize the number of read/write operations required.

D. Consolidating all data into a single large table to simplify management.

A. Exadata Database Service uses a completely different SQL parsing engine compared to a traditional Oracle Database.

B. Exadata Database Service integrates specialized, high-performance storage servers and a high- bandwidth, low-latency RDMA over Converged Ethernet (RoCE) network, optimized for database workloads, which are not present in typical cloud VM deployments.

C. Exadata Database Service exclusively supports Oracle RAC, while traditional cloud deployments can support both single-instance and RAC databases.

D. Exadata Database Service utilizes only virtualized compute nodes, while traditional deployments use bare metal.

A. Block Volumes provide the primary storage and are directly attached to the VM.

B. Local NVMe storage is always the default for BaseDB.

C. Object Storage is the default storage option for database datafiles.

D. File Storage is mandatory for database backups.

A. Data is organized into tables with predefined schemas, similar to relational databases.

B. Data is structured in a graph format, representing entities as nodes and relationships as edges.

C. Each data item is uniquely identified by a key, and the associated value can be any data type or structure.

D. Data is stored as JSON documents with flexible structures, allowing for nested elements.

E. Relationships between data items are explicitly defined through foreign keys and joins.

A. Apply the Grid Infrastructure patch directly to the DB system. OCI handles the patching order for all components automatically.

B. You cannot manually patch Grid Infrastructure in a BaseDB VM system; Oracle Cloud Infrastructure manages all patching operations.

C. Apply the database patch first, then apply the Grid Infrastructure patch to ensure compatibility.

D. Apply the Grid Infrastructure patch first, then apply the database patch, after validating the GI is working correctly.

A. Enforcement of strict referential integrity constraints.

B. Support for complex joins and transactions across multiple tables.

C. Partitioning and replication of data across multiple nodes.

D. Reliance on a centralized, single-instance architecture.
