CompTIA Security+ (SY0-701)Security ArchitectureHard
A global SaaS provider replicates its production database synchronously across data centers in two different geographic regions so that a regional disaster does not cause data loss or extended downtime. Which resilience concept does this design primarily illustrate?
- ALoad balancing
- BTokenization
- CGeographic dispersion
- DData classification
Show answer & explanationAnswer & explanation
Correct answer: C. Geographic dispersion
Geographic dispersion spreads infrastructure and data across physically separate regions so that a localized disaster (natural, power, political) does not take down the entire service, supporting both availability and disaster recovery goals.
Why the other options are wrong
- A. Load balancing distributes traffic across servers for performance/availability but doesn't specifically address regional disaster resilience.
- B. Tokenization replaces sensitive data with tokens for compliance scope reduction, not a resilience/DR concept.
- D. Data classification categorizes data by sensitivity, unrelated to physical location resilience.
Geographic Dispersion
A resilience strategy that distributes systems, data, and infrastructure across physically separate locations to reduce the risk that a single regional event causes total outage or data loss.
- Mitigates regional disasters (earthquakes, power grid failures)
- Often paired with synchronous or asynchronous replication
- Key design factor in multi-region cloud architectures
Memory trick: Don't put all your servers in one region's basket.
