Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 21
A developer has created an application based on customer requirements. The customer needs to run the application with the minimum downtime.
Which design approach regarding high-availability applications, Recovery Time Objective, and Recovery Point Objective must be taken?
Answer options
- A. Active/passive results in lower RTO and RPO. For RPO, data synchronization between the two data centers must be timely to allow seamless request flow.
- B. Active/passive results in lower RTO and RPO. For RPO, data synchronization between the two data centers does not need to be timely to allow seamless request flow.
- C. Active/active results in lower RTO and RPO. For RPO, data synchronization between the two data centers does not need to be timely to allow seamless request flow.
- D. Active/active results in lower RTO and RPO. For RPO, data synchronization between the two data centers must be timely to allow seamless request flow.
Correct answer: D
Explanation
The correct answer is D because an active/active setup provides better RTO and RPO by allowing both data centers to handle traffic simultaneously, thus minimizing downtime. Options A and B refer to active/passive setups, which do not achieve the same level of availability. Option C, while mentioning active/active, incorrectly states that timely data synchronization is not necessary, which is crucial for maintaining data integrity and seamless operation.
