You are the Cloud Architect of a company, and are designing a solution on Oracle Cloud Infrastructure where you want to have all your compute instances resistant to hardware failure.

Which two are recommended best practices to achieve the requirement on Oracle Cloud Infrastructure? (Choose two.)

  1. Create a custom image of your system drive each time you change the image.
  2. Attach block volumes from different Availability Domains to compute instances in different Availability Domains for high availability.
  3. Design your system with redundant compute modes in different Availability Domains to support the failover capability.
  4. Create backups of your block volumes that are associated with compute instances in different regions.

Answer(s): A,C

Explanation:

System ResilienceOracle Cloud Infrastructure runs on Oracle's high-quality Sun servers. However, any hardware can experience a failure. Follow industry-wide hardware failure best practices to ensure the resilience of your solution. Some best practices include:

Design your system with redundant compute nodes in different availability domains to support fail-over capability.Create a custom image of your system drive each time you change the image.Back up your data drives, or sync to spare drives, regularly.If you experience a hardware failure and have followed these practices, you can terminate the failed instance, launch your custom image to create a new instance, and then apply the backup data.

Which statement is true about restoring a block volume from a manual or policy-based block volume backup?

  1. It can be restored as new volumes to any Availability Domain within the same region.
  2. It must be restored as new volumes to the same Availability Domain on which the original block volume backup resides.
  3. It can be restored as new volumes to any Availability Domain across different regions.
  4. It can be restored as new volumes with different sizes from the backups.

Answer(s): A



Which two statements are true about data guard service on DB Systems in Oracle Cloud Infrastructure (OCI)? (Choose two.)

  1. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal
  2. Data guard configuration on the OCI is limited to one standby database per primary database
  3. Data guard configuration on the OCI is limited to a virtual machine only
  4. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database

Answer(s): B,D



Your company is developing a new database application in Oracle Cloud Infrastructure. You need to test application functionality including a hardware failure scenario. Since the application is still in the development phase, you want to minimize infrastructure costs.

Which database service deployment option meets this requirement?

  1. two node real application cluster (RAC) system
  2. Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality
  3. two node bare metal system with data guard enabled
  4. single node bare metal system

Answer(s): A
