An order-entry application must survive a single server failure and continue serving users if the primary site becomes unavailable. Management wants automatic failover, but does not want to pay for fully active production capacity in two regions. Which design is best?

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.

A

Distractor review

Run one server and keep nightly backups in cloud object storage.

Backups help recovery after loss, but they do not provide automatic service continuity during an outage.

B

Best answer

Use two servers in one site behind a load balancer and maintain an asynchronously replicated warm standby site.

This provides local redundancy for server failure and a lower-cost secondary site for failover if the primary site is lost.

C

Distractor review

Deploy active-active multi-region capacity with identical production load in both regions.

Active-active meets the availability goal, but it usually costs more than the scenario allows and duplicates production capacity.

D

Distractor review

Add RAID 1 and a spare power supply to the database server.

These hardware controls improve a single server’s reliability, but they do not address a site outage or application-level failover.

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 SY0-701 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: Use two servers in one site behind a load balancer and maintain an asynchronously replicated warm standby site. — A load-balanced pair in the primary site handles a single server failure, while an asynchronously replicated warm standby site provides a lower-cost recovery path if the primary site is lost. That gives the organization automatic failover capability without paying for two fully active regions. It is a practical compromise between resilience and cost, which matches the business requirement better than backups alone or full active-active design. Why others are wrong: Nightly backups are necessary, but they are not a continuity solution. Active-active multi-region deployment is stronger from a resilience standpoint, but it violates the cost constraint by keeping full production capacity in both regions. RAID and a spare PSU help a single machine survive component failure, yet they do nothing for a regional or site-wide outage.
