  D. Block Storage Service

• Question 232:

  You have an application running on Oracle Cloud Infrastructure. You Identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard2.1 compute without any block storage attached to it. Which two options allow you to increase disk IOPS performance?

  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.DenseI02.8 shape using the boot volume preserved and use the NVMe devices to host your application.
  B. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved and attach a new block volume to host your application.
  C. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved, but no block volume attached.
  D. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.
  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.DenseI02.8 shape using the boot volume preserved and use the NVMe devices to host your application.
  D. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.

• Question 236:

  There are multiple options of migrating Oracle Databases from on-premises to Oracle Cloud Infrastructure. Which two characteristics do you need to consider when choosing a migration method? (Choose two.)

  A. On-premises database character set and application version
  B. On-premises database version and quantity of data, including indexes
  C. On-premises host operating system platform and network bandwidth
  D. On-premises connectivity using remote and local VCN peering
  B. On-premises database version and quantity of data, including indexes
  C. On-premises host operating system platform and network bandwidth

  References: https://docs.cloud.oracle.com/iaas/Content/Database/Tasks/migrating.htm Some of the characteristics and factors to consider when choosing a migration method are: On-premises database version Database service database version On-premises host operating system and version On-premises database character set Quantity of data, including indexes Data types used in the on-premises database Storage for data staging Acceptable length of system outage Network bandwidth

• Question 237:

  Which three can you achieve by using Terraform? (Choose three.)

  A. Create resources in the right order without regard to the order in the terraform plan file.
  B. Automatically re-provision the resources that are tainted or whose configuration has changed.
  C. Automatically translate a deployed infrastructure and create a plan.
  D. Automatically destroy all the resources that are in tenancy.
  E. Continuously maintain the configuration files in an instance.
  A. Create resources in the right order without regard to the order in the terraform plan file.
  B. Automatically re-provision the resources that are tainted or whose configuration has changed.
  D. Automatically destroy all the resources that are in tenancy.

• Question 238:

  You are running a mission-critical database application in Oracle Cloud Infrastructure (OCI). You take regular backups of your DB system to OCI object storage. Recently, you notice a failed database backup status in the console. What step can you take to determine the cause of the backup failure?

  A. Ensure that your database host can connect to OCI object storage.
  B. Ensure the database archiving mode is set to NOARCHIVELOG.
  C. Make sure that the database is not active and running while the backup is in progress.
  D. Don't restart the dcsagent program even if it has a status of stop/waiting.
  A. Ensure that your database host can connect to OCI object storage.

  Database backups can fail for various reasons. Typically, a backup fails because either the database host cannot access the object store, or there are problems on the host or with the database configuration. First need to determining the Problem In the Console, a failed database backup either displays a status of Failed or hangs in the Backup in Progress or Creating state. If the error message does not contain enough information to point you to a solution, you can use the database CLI and log files to gather more data. Then, refer to the applicable section in this topic for a solution. Database Service Agent Issues Your Oracle Cloud Infrastructure Database makes use of an agent framework to allow you to manage your database through the cloud platform. Occasionally you might need to restart the dcsagent program if it has the status of stop/waiting to resolve a backup failure. Object Store Connectivity Issues Backing up your database to Oracle Cloud Infrastructure Object Storage requires that the host can connect to the applicable Swift endpoint. You can test this connectivity by using a Swift user. Host Issues One or more of the following conditions on the database host can cause backups to fail:

  -Interactive Commands in the Oracle Profile

  -The File System Is Full

  -Incorrect Version of the Oracle Database Cloud Backup Module

  -Changes to the Site Profile File (glogin.sql)

  Database Issues

  An improper database state or configuration can lead to failed backups.

  -Database Not Running During Backup

  - Archiving Mode Set to NOARCHIVELOG (When you provision a new database, the archiving mode is set to ARCHIVELOG by default. This is the required archiving mode for backup operations)

  -Stuck Database Archiver Process and Backup Failures

  -Temporary Tablespace Errors

  -

  RMAN Configuration and Backup Failures

  -

  RMAN Retention Policy and Backup Failures

  -Loss of Objectstore Wallet File and Backup Failures

  TDE Wallet and Backup Failures

  -

  Incorrect TDE Wallet Location Specification

  -

  Incorrect State of the TDE Wallet

  -

  Incorrect Configuration Related to the TDE Wallet

  -Missing TDE Wallet File

  As this is not new provisioned database and already in the ARCHIVELOG , regular backups of DB system to OCI object storage in places, so the best answers are,

  - Ensure that your database host can connect to the OCI object storage

  -Restart the database service agent

  B. Data guard configuration on the OCI is limited to one standby database per primary database
  C. Data guard configuration on the OCI is limited to a virtual machine only
