Oracle 1Z0-1093-25 Online Questions & Answers

• Question 1:

  When provisioning an Exadata Database Service, which two networking components are mandatory?

  A. A public subnet for the Exadata Infrastructure to allow external access for monitoring.
  B. A Service Gateway to allow access to Oracle Services without traversing the public internet.
  C. A private subnet for the client network to ensure secure database access.
  D. A NAT Gateway for each VM within the VM Cluster to allow outbound internet access for patching.
  E. A private subnet for database backups to Oracle Cloud Infrastructure Object Storage.
  C. A private subnet for the client network to ensure secure database access.
  E. A private subnet for database backups to Oracle Cloud Infrastructure Object Storage.

• Question 2:

  You are responsible for managing the storage configuration of an Exadata Database Service (ExaDB). You need to use the cellcli utility to modify the IORM (I/O Resource Management) settings to prioritize critical database workloads. Specifically, you want to adjust the share allocation for a specific database. Which cellcli command will accomplish this?

  A. cellcli alter iormplan database dbname shares=value
  B. cellcli configure iormplan database dbname shares=value
  C. cellcli modify iormplan database dbname shares=value
  D. cellcli change iormplan database dbname shares=value
  A. cellcli alter iormplan database dbname shares=value

• Question 3:

  Which statement accurately reflects the impact of applying an Oracle-provided patch to the operating system on an Exadata Database Service instance using the Oracle Cloud Infrastructure (OCI) console?

  A. The OCI console-initiated patch process only updates the database software, leaving the underlying OS untouched.
  B. The OCI console-initiated patch process automatically updates both the database software and the underlying operating system on all compute and storage nodes concurrently.
  C. The OCI console-initiated patch process updates the database software and the OS, allowing for a rolling update strategy on the database nodes, minimizing downtime. Storage nodes are updated separately.
  D. The OCI console-initiated patch process only patches the storage servers; database nodes require manual OS patching.
  C. The OCI console-initiated patch process updates the database software and the OS, allowing for a rolling update strategy on the database nodes, minimizing downtime. Storage nodes are updated separately.

• Question 4:

  Which two statements are accurate regarding the lifecycle management of an Exadata VM Cluster?

  A. The VM Cluster can be independently stopped and started without impacting the underlying Exadata Infrastructure.
  B. The VM Cluster's CPU core count can be dynamically scaled up or down without requiring a reboot.
  C. Patching the Exadata Infrastructure automatically patches the VM Cluster and databases.
  D. Modifying the shape of the Exadata Infrastructure automatically scales the VM Cluster resources proportionally.
  E. The VM Cluster can be terminated independently, allowing reuse of the Exadata Infrastructure for a different VM Cluster.
  A. The VM Cluster can be independently stopped and started without impacting the underlying Exadata Infrastructure.
  E. The VM Cluster can be terminated independently, allowing reuse of the Exadata Infrastructure for a different VM Cluster.

• Question 5:

  Within the context of Exadata Database Service, what does scaling out primarily refer to?

  A. Increasing the CPU core count of a single database server VM.
  B. Adding additional database server VMs and storage servers to the Exadata system.
  C. Upgrading the version of the Oracle Database software.
  D. Expanding the amount of RAM available to a single database instance.
  B. Adding additional database server VMs and storage servers to the Exadata system.

• Question 6:

  You are managing an Exadata Database Service (ExaDB) and need to perform a full backup of the database to Oracle Cloud Infrastructure Object Storage using the bkup_api utility. The backup must include all datafiles and control files.

  Which bkup_api command will achieve this?

  A. bkup_api bkup_start --dbname=dbname
  B. bkup_api bkup_start --datafiles --controlfile --dbname=dbname
  C. bkup_api bkup_start --full --dbname=dbname
  D. bkup_api bkup_start --all --dbname=dbname
  C. bkup_api bkup_start --full --dbname=dbname

• Question 7:

  Which two statements regarding the use of tags in conjunction with Database Management for monitoring are true?

  A. Tags can be used to group databases for easier monitoring and analysis in Database Management.
  B. Tags propagate automatically from the database to Database Management; no additional configuration is required.
  C. Tags can be used to filter and search for specific databases within the Database Management console.
  D. Database Management does not support the use of tags for any monitoring or filtering purposes.
  A. Tags can be used to group databases for easier monitoring and analysis in Database Management.
  C. Tags can be used to filter and search for specific databases within the Database Management console.

• Question 8:

  Which two requirements must be met first to create an Exadata Database Service Instance?

  A. You only need a VCN and Universal Cloud Credits.
  B. You need to define the VCN, Private Client subnet, and Service Backup subnet.
  C. You need to define the VCN, Private Client subnet, and Private Backup subnet.
  D. There are no prerequisites for creating an Exadata Database Service instance.
  E. You need to create an Exadata Infrastructure and VM Cluster resource.
  C. You need to define the VCN, Private Client subnet, and Private Backup subnet.
  E. You need to create an Exadata Infrastructure and VM Cluster resource.

• Question 9:

  What is the primary processing paradigm employed by the HeatWave query accelerator for analytical workloads?

  A. Row-based processing
  B. Disk-based processing
  C. Columnar processing
  D. Index-based processing
  E. Key-value pair processing
  C. Columnar processing

• Question 10:

  When using a NoSQL Database Cloud Service SDK, what is the purpose of handling exceptions or errors returned by the SDK?

  A. To automatically recover from hardware failures in the cloud.
  B. To ensure data consistency by retrying failed operations.
  C. To provide detailed performance metrics to the database administrators.
  D. To implement custom logic for handling specific error conditions, such as record not found or insufficient capacity.
  D. To implement custom logic for handling specific error conditions, such as record not found or insufficient capacity.
