PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A project manager is selecting a data center for a new application that requires high availability and disaster recovery. Which type of data center arrangement is most appropriate?
⚠ Common exam trap
The PK0-005 exam often tests the misconception that active-passive is sufficient for high availability, but candidates overlook that active-passive introduces failover latency and potential data loss, whereas active-active provides continuous service with no manual intervention.

Correct answer & explanation
✓
Active-active
An active-active data center arrangement is most appropriate for high availability and disaster recovery because it distributes application traffic across multiple geographically dispersed data centers, all of which are actively serving requests. If one site fails, traffic is seamlessly redirected to the remaining active sites, ensuring near-zero downtime and no data loss. This configuration supports automatic failover and load balancing, which are critical for meeting stringent recovery time objectives (RTO) and recovery point objectives (RPO).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Active-active
Why this is correct
Active-active allows multiple sites to handle traffic simultaneously, providing high availability and disaster recovery.
- ✗
Single site
Why it's wrong here
Single site offers no redundancy, making it unsuitable for high availability and disaster recovery.
- ✗
Active-passive
Why it's wrong here
Active-passive provides failover but does not ensure continuous availability as traffic must switch over.
- ✗
Colocation
Why it's wrong here
Colocation only provides space, power, and cooling; it does not inherently offer redundancy or failover.
