A customer portal must recover from a regional outage within a few hours. The business wants lower ongoing cost than a fully active second Region and does not want to rebuild everything from scratch during the outage. Which two DR patterns best fit that goal? Select two.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Distractor review
Backup and restore
This is the lowest-cost option, but recovery usually requires rebuilding much of the environment after a disaster.
Best answer
Pilot light
Pilot light keeps only core components running in the secondary Region, which lowers cost while reducing recovery time.
Best answer
Warm standby
Warm standby keeps a scaled-down but functional environment ready, which shortens recovery while avoiding full active-active cost.
Distractor review
Multi-site active-active
Active-active improves availability, but it runs production in multiple Regions continuously and costs more than the stated goal.
Distractor review
Single-AZ deployment
A single-AZ design is not a regional disaster recovery strategy and does not meet the recovery objective.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Pilot light — Pilot light and warm standby are the two DR patterns that best balance cost and recovery speed for a business that wants a pre-provisioned secondary Region without paying for a full active-active stack. Pilot light keeps only the essential foundation running, while warm standby keeps a smaller but operational environment ready to scale up. Both reduce recovery time significantly compared with rebuilding everything from backups. Why others are wrong: Backup and restore is cheaper but usually slower because the environment must be recreated during the incident. Multi-site active-active gives the fastest recovery, but it runs too much production capacity to match the stated cost constraint. Single-AZ deployment does not provide regional disaster recovery and is not an acceptable tradeoff here.
