A payment application must keep running if one application server fails, and the business can tolerate no more than 5 minutes of lost transactions and 30 minutes of downtime during a site outage. Which two controls best match the availability requirements? 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.
Best answer
Deploy at least two active application nodes behind a load balancer so one server failure does not interrupt service.
A load balancer with multiple active nodes removes the single-server dependency and lets traffic continue if one node fails or is taken down for maintenance. This directly addresses the requirement to survive an application server failure without stopping the service. It is a standard high-availability design for front-end and application tiers.
Distractor review
Use a cold site that is powered off until a disaster is declared.
A cold site may eventually support disaster recovery, but it usually has a long startup delay and does not meet a 30-minute downtime target. It is too slow for an environment that must recover quickly from a site outage and keep transactions flowing with minimal interruption.
Best answer
Configure near-real-time database replication or synchronous replication to a standby so recent transactions are preserved.
Replication to a standby system is the correct way to reduce data loss when the primary site or storage fails. Near-real-time or synchronous replication can keep the recovery point within the 5-minute requirement, depending on latency and design. Combined with failover, it protects both availability and recent transaction integrity.
Distractor review
Take nightly backups to meet the 5-minute recovery point objective.
Nightly backups create a much larger potential data-loss window than 5 minutes. Backups are essential for recovery, but they are not a substitute for replication when the business needs very low RPO. This option does not match the stated transaction-loss tolerance.
Distractor review
Rely on weekly VM snapshots because they are faster than replication.
Weekly snapshots are far too infrequent for a 5-minute recovery point objective and do not provide continuous availability. Snapshots can help with point-in-time rollback, but they do not replace real-time replication or failover for a payment system with strict uptime requirements.
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: Deploy at least two active application nodes behind a load balancer so one server failure does not interrupt service. — The correct architecture is active redundancy for the application tier plus near-real-time replication for the transaction data. Load balancing keeps the service available if one application node fails, while replication and failover protect the database against site or storage loss with minimal data loss. Together, those controls address both uptime and recovery-point requirements in a practical, layered way. Why others are wrong: A cold site takes too long to activate, so it cannot satisfy a 30-minute outage target. Nightly backups and weekly snapshots may support recovery, but they allow too much data loss for a 5-minute RPO. The scenario requires continuous or near-continuous protection, not periodic rollback points that leave many transactions unrecoverable.
