What are the two main types of deployment strategies?

• Redeploy

• Recreate

• Rolling update

• Rolling upgrade

There are a couple of other strategies as well that are not specified as an option in the deployment, but they can be implemented in a different way: ___________ and ___________.

• Canary

• Recreate

• Rolling update

• Rolling upgrade

• Blue green

In Kubernetes it involves running two environments: the current version and the new version. Traffic is routed to new version after verifying it works, ensuring zero-downtime. If issues arise, traffic can quickly revert to the old version for a safe rollback.

The traffic is switch by using the service selectors.

What type of deployment strategy does the above statement refer to?

• Canary

• Recreate

• Rolling update

• Rolling upgrade

• Blue green

In this strategy, we deploy a new version and we route a small percentage of traffic to it. The majority of traffic is routed to the older version. At this point, we run tests, and if everything looks good, we upgrade the original deployment with the newer version of the application.

What type of deployment strategy does the above statement refer to?

• Canary

• Recreate

• Rolling update

• Rolling upgrade

• Blue green

In this strategy, both deployments, the older and the new one have a common label.

• The service is always pointing out to both deployments by using the selector.

What type of deployment strategy does the above statement refer to?

• Canary

• Recreate

• Rolling update

• Rolling upgrade

• Blue green

In this strategy, we can create the second deployment just with one or a few of replicas, and when all tests pass, we can increase the number of replicas on the new one, and decrease the number of replicas of the older version.

What type of deployment strategy does the above statement refer to?

• Canary

• Recreate

• Rolling update

• Rolling upgrade

• Blue green

In Canary deployment solutions, what type of solution we should use to define the exact percentage of traffic we want to distribute between each deployment?

• Distributed Tracing and Observability Platforms

• Service Discovery solutions

• Service mesh platform solutions

• API Gateway Solutions

• Network Policy solutions

They are used to run a set of pods to perform a given task to completion.

• Pods

• Jobs

• ReplicaSets

• Cronjobs

• Container

It is a job that can be scheduled, just like ___________ in Linux.
