Cisco Exam 300-910 Topic 2 Question 69 Discussion

Actual exam question for Cisco's 300-910 exam

Question #: 69
Topic #: 2

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.

That's true, but blue/green deployment is more commonly used for this type of situation.

But canary deployment could also work, right? It allows for a gradual rollout to a subset of users.

I agree with William. Blue/green deployment is the most suitable for this scenario.

I think the answer is blue/green deployment because it allows for zero downtime.

I believe the shadow deployment strategy could also be considered, as it allows testing in a production-like environment without impacting users.

I agree with Tegan. Using the blue/green deployment strategy ensures zero downtime during the release.

Rolling deployment does sound like the way to go. That way we can gradually roll out the new version and easily roll back if we run into any issues. Plus, it's a pretty standard approach for this kind of scenario.

Hmm, I'm not sure about the canary approach. That's usually more for testing new features with a small subset of users, not a full version migration. I'm leaning more towards the rolling deployment.

Yeah, I agree. Blue/green is out. I'm thinking either the rolling or canary strategy would work here. The key is being able to gradually shift traffic to the new version without interrupting service.

Oh god, Tom, don't even joke about that. Can you imagine the chaos? 'Why is my order not showing up?' 'Sorry, it's just in the shadow realm right now.'
