3.1 Define methods of deploying and operating in the AWS Cloud.
Objective 3.1 sits in Cloud Technology and Services, which carries 34% of the Cloud Practitioner exam. The questions below are original, written from the official objective title above, and each explanation cites the AWS page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A team hand-builds the same Auto Scaling group, load balancer, and RDS instance in three Regions. Which service provisions all three from one template?
The concept
Infrastructure as code moves the definition of an environment into a file you version, review and reapply. The provisioning engine reads that file and creates whatever it describes.
Why this answer
You describe the group, the balancer and the database once, then create a stack from that file in each Region. The order the resources have to come up in is worked out for you.
- AConfig records how your resources are configured and evaluates them against rules. It reports drift after the fact rather than creating anything.
- BCodeDeploy pushes application revisions onto instances that already exist. It answers how code reaches a fleet, not how the fleet gets built.
- Correct. A CloudFormation template describes the AWS resources you want, and CloudFormation provisions and configures those resources for you.
- DSystems Manager operates nodes you already have: patching, running commands, session access. That is day two work, after the stack is standing.
Now you: objective 3.1 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
An operations team needs to run patch commands across hundreds of EC2 instances without bastion hosts or open SSH ports. Which service handles that?
Sample question 2 of 3
You need to script routine AWS tasks from a bash shell, without writing application code. Which interface fits?
Sample question 3 of 3
Several EC2 instances do not appear in the Systems Manager node list. What has to be true before an instance counts as a managed node?
That’s 3 of the full Cloud Practitioner bank.
