Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A customer portal runs on a single application server behind a database cluster. Leadership wants the portal to keep working if that application server fails, but the budget is tight and the team wants the simplest design that can automatically fail over. What should they add?
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
Best answer
A second application server configured as an active-passive failover pair with health checks.
An active-passive pair provides automatic failover for a single server failure without the cost and complexity of a larger multi-node design. Health checks let the standby take over when the primary becomes unavailable, which matches the stated availability goal and budget constraint.
B
Distractor review
A cold backup server that is started manually after the outage is detected.
A cold backup is inexpensive, but failover is not automatic and recovery takes longer. That does not meet the requirement for automatic continuation of service after a server failure.
C
Distractor review
A multi-region active-active deployment with global traffic steering.
Active-active across regions provides strong resilience, but it is far more expensive and operationally complex than the scenario requires. It is also not the simplest low-cost solution for a single application server failure.
D
Distractor review
Additional RAID storage in the application server to prevent service interruption.
RAID protects disks from certain drive failures, but it does not provide application-server redundancy. If the server itself fails, the portal can still go down even when the storage is mirrored or striped.
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: A second application server configured as an active-passive failover pair with health checks. — The best choice is a second application server in an active-passive failover configuration with health checks. That gives the portal automatic continuity if the primary application server fails, without the cost and complexity of a multi-region or active-active architecture. It is a common resilience pattern when the business wants a practical improvement in availability and only needs protection from one server outage. Why others are wrong: A cold backup requires manual intervention and increases downtime. Active-active multi-region designs are stronger but more expensive and operationally heavy than necessary. RAID protects storage media, not application availability, so it cannot substitute for server redundancy.
