Which two should be considered when designing a fault tolerant solution in Oracle Cloud Infrastructure (OCI)?

Question

Options

• Aensuring your solution components are distributed across OCI Fault Domains
• Bperforming data integrity check when using OCI File Storage Service
• Cwriting custom scripts that will monitor your solution
• Dusing multiple OCI Availability Domains (AD), where available, to deploy your solution
• Ecreating a manual cluster of compute instances

• A
  78% (43)
• B
  5% (3)
• C
  13% (7)
• E
  4% (2)

Explanation

Creating a manual cluster of compute instances, and Writing custom scripts that will monitor your solution are not valid ways to ensure fault tolerance at all. Also, Performing Data Integrity check when using OCI File Storage Service is not valid since OCI takes care of it. Therefore, we are left with: 1) Using multiple OCI Availibility Domains (AD), where available, to deploy your solution -Which is excellent because we have multiple AD's so that if one fails, we have a backup AD! 2) Ensuring your solution components are distributed across OCI Fault Domains -So that we can protect our deployment against unexpected power failures, AD failure etc. domains-to-improve-application-resiliency
