Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 422

An organization manages a large cloud-deployed application that employs a microservices architecture across multiple data centers. Reports have been received about application slowness. The container orchestration logs show that faults have been raised in a variety of containers that caused them to fail and then spin up brand new instances.
Which two actions can improve the design of the application to identify the faults? (Choose two.)

Answer options

• A. Automatically pull out the container that fails the most over a time period.
• B. Implement a tagging methodology that follows the application execution from service to service.
• C. Add logging on exception and provide immediate notification.
• D. Do a write to the datastore every time there is an application failure.
• E. Implement an SNMP logging system with alerts in case a network link is slow.

Correct answer: B, C

Explanation

Option B is correct because implementing a tagging methodology helps to trace the flow of execution through services, making it easier to identify where faults occur. Option C is also correct as adding logging on exceptions with immediate notifications allows for quick identification and response to issues. Options A, D, and E do not directly address identifying faults in the application design as effectively as B and C.
