What does RTO (Recovery Time Objective) define in a CIS disaster recovery plan?
Answer: The maximum acceptable duration of system downtime before operations must be restored
RTO is the maximum time a business can tolerate a system being unavailable after a disruption, guiding the design of recovery capabilities.
RPO (Recovery Point Objective) in a CIS implementation refers to:
Answer: The maximum amount of data loss, measured in time, that is acceptable after a disruption
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.
In CIS infrastructure, 'high availability' is typically achieved through:
Answer: Redundancy and failover mechanisms that eliminate single points of failure
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.
What is the purpose of environment promotion in a CIS implementation (Dev → QA → UAT → Production)?
Answer: To progressively validate changes through controlled stages before they reach end users
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.
Which practice ensures that CIS infrastructure configuration is version-controlled and can be consistently reproduced?
Answer: Infrastructure as Code (IaC) using tools like Terraform or Ansible
Infrastructure as Code treats infrastructure configuration as software, storing it in version control systems so environments can be consistently provisioned, audited, and reproduced.
What is the MOST important consideration when sizing server infrastructure for a new CIS implementation?
Answer: Anticipated user concurrency, data volume, and transaction throughput requirements
Proper infrastructure sizing must account for peak concurrent users, expected data volumes, and transaction rates to ensure performance under real-world load conditions.
