Exhibit

Order service topology:
Internet -> Load balancer -> App Server A
Internet -> Load balancer -> App Server B
Database -> Single instance in AZ1
Application servers are stateless.
Requirement: service must continue if one app server goes down, with no manual failover steps.

Based on the exhibit, which architecture best meets the goal of keeping the order service running if one application server fails?

Based on the exhibit, which architecture best meets the goal of keeping the order service running if one application server fails?

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

Use one active server with a warm standby server that is started manually during outages.

A warm standby can recover service, but manual activation delays failover and reduces availability.

B

Best answer

Run the application servers active-active behind the load balancer.

Active-active design keeps service available because surviving servers continue handling traffic automatically.

C

Distractor review

Store the application binaries on RAID 1 disks to prevent service interruption.

RAID helps with storage resilience, but it does not provide application-server redundancy by itself.

D

Distractor review

Take nightly backups of the application servers and restore them after a failure.

Backups help recovery after loss, but they do not provide continuous service when a server fails.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

FAQ

Questions learners often ask

What does this SY0-701 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Run the application servers active-active behind the load balancer. — Active-active application servers behind the load balancer best satisfy the requirement. Because the servers are stateless, either node can continue serving requests if the other fails, and the load balancer can automatically direct traffic to the remaining healthy node. That gives the organization fault tolerance without waiting for a manual promotion step. The database is still a separate concern, but the question specifically asks about surviving a single application server failure. Why others are wrong: A warm standby still depends on manual or delayed failover. RAID protects disks, not application availability. Backups are a recovery mechanism, not a high-availability mechanism, so they do not keep the service online during an outage.
