Question 1

What does RTO (Recovery Time Objective) define in a CIS disaster recovery plan?

Accepted Answer

The maximum acceptable duration of system downtime before operations must be restored

Answer

RTO is the maximum time a business can tolerate a system being unavailable after a disruption, guiding the design of recovery capabilities.

Question 2

RPO (Recovery Point Objective) in a CIS implementation refers to:

Accepted Answer

The maximum amount of data loss, measured in time, that is acceptable after a disruption

Answer

RPO defines how much data loss is acceptable; for example, an RPO of 1 hour means backups must occur at least every hour so no more than 1 hour of data can be lost.

Question 3

In CIS infrastructure, 'high availability' is typically achieved through:

Accepted Answer

Redundancy and failover mechanisms that eliminate single points of failure

Answer

High availability is achieved by eliminating single points of failure through redundant components, load balancing, and automated failover so the system remains operational even when individual components fail.

Question 4

What is the purpose of environment promotion in a CIS implementation (Dev → QA → UAT → Production)?

Accepted Answer

To progressively validate changes through controlled stages before they reach end users

Answer

Environment promotion ensures that code and configuration changes are tested and validated at each stage before reaching production, reducing the risk of defects affecting end users.

Question 5

Which practice ensures that CIS infrastructure configuration is version-controlled and can be consistently reproduced?

Accepted Answer

Infrastructure as Code (IaC) using tools like Terraform or Ansible

Answer

Infrastructure as Code treats infrastructure configuration as software, storing it in version control systems so environments can be consistently provisioned, audited, and reproduced.
