Cisco Exam 300-910 Topic 7 Question 81 Discussion

Actual exam question for Cisco's 300-910 exam

Question #: 81
Topic #: 7

A team must roll out updates on the production instance of an application. To avoid any service down time, the new version must be released alongside the old version. After the team ensures that the new version operates as it should, traffic will be redirected to the new version. Then the old version will be shut down.

Which deployment strategy must be used?

Arolling

Bblue/green

Cshadow

Dcanary

Show Suggested Answer

Suggested Answer: B

The new version of the application is deployed to one of the environments, and then traffic is gradually shifted to the updated environment. This strategy allows the team to test the new version before releasing it to the public, ensuring that it is operating as expected. After the new version is tested and approved, traffic is fully shifted to the new environment and the old environment is shut down.

Blue/green is the clear winner here. It's like wearing two pairs of pants at the same time - you never know when you might need that backup version!

I see your point, Alecia. Canary deployment does offer more control over the release process.

Rolling deployment? Sounds like a recipe for a rollback disaster! Better keep the old and new versions running side-by-side for a smooth transition.

D: Shadow deployment might be a good option too, running the new version alongside the old one for monitoring purposes.

Shadow deployment sounds like a good option. You can test the new version without impacting the production environment. Just don't forget to clean up those shadows afterwards!
