3.4 Explain the importance of resilience and recovery in security architecture
Objective 3.4 sits in Security Architecture, which carries 18% of the Security+ exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A company is designing a mission-critical workload that must withstand both a single zone outage and a full-region outage. Which design should it use?
The concept
Different failure scopes require different levels of platform diversity in the architecture.
Why this answer
For mission-critical workloads, a design that spans multiple regions and multiple zones is recommended to withstand both zone-level and region-level failures.
- AA single zone provides no protection against that zone's own outage.
- BNonzonal placement leaves resources vulnerable if the affected zone is included.
- Correct: combining multi-region and multi-zone covers both failure scopes.
- DLRS without cross-region replication cannot withstand a full-region outage.

Sample question 1 of 3
A security engineer wants backup data protected against ransomware while it moves to storage and while it is stored. What must be ensured?
Sample question 2 of 3
A workload runs across two availability zones with automatic replication and failover managed by the provider. One zone loses power from a local outage. What best describes this outcome?
Sample question 3 of 3
What is the approximate round-trip latency target for network links between availability zones in a region?
