A customer portal must stay online if one application server fails. Which two design choices improve availability? 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.
A
Best answer
Use load balancing across multiple application servers.
Load balancing spreads traffic across more than one server, so the portal can keep working if one node becomes unavailable. It is one of the most common availability designs for web applications.
B
Best answer
Add a redundant standby server or failover target.
A standby or failover server provides an alternate system if the primary server stops responding. This redundancy helps maintain service continuity and reduces downtime.
C
Distractor review
Store the application logs on a larger disk.
A larger log disk may help with storage capacity, but it does not keep the portal online if an application server fails. It is not an availability control.
D
Distractor review
Increase the password length requirement for portal users.
Stronger passwords are useful for authentication, but they do not provide redundancy or failover. They do not help the service survive a server outage.
E
Distractor review
Place all traffic on a single high-performance server.
A single server creates a single point of failure. Better performance does not equal fault tolerance, so this choice does not improve availability.
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 load balancing across multiple application servers. — Availability depends on removing single points of failure. Load balancing allows traffic to continue flowing to healthy servers, and a standby or failover server gives the system an alternate path if the primary node goes down. Together, these controls are simple examples of fault tolerance and are much more effective than trying to make one server stronger. Why others are wrong: More disk space and stronger passwords do not help when the application server fails. A single fast server is still a single point of failure, so it is not a resilient design. Availability requires redundancy and failover, not just better performance on one machine.
