Full question →mediummultiple choiceObjective-mapped
A monthly scan finds a critical remote-code-execution issue on an internet-facing VPN appliance. The vendor has released a fix, but the appliance can only be rebooted during the weekend maintenance window in five days. What is the BEST immediate action to lower risk until patching can occur?
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
Apply a compensating control such as restricting access to trusted source IPs and disabling nonessential remote access features
A compensating control lowers exposure right away when the patch cannot be installed immediately, which is the safest short-term option.
B
Distractor review
Wait for the weekend because the exploit is not confirmed
Waiting leaves a critical internet-facing vulnerability exposed and ignores the fact that risk exists even without confirmed exploitation.
C
Distractor review
Remove logging from the appliance to improve performance during the wait
Removing logs reduces visibility and makes investigation harder without reducing the actual vulnerability.
D
Distractor review
Run another scan every hour and do nothing else
Repeated scanning increases noise but does not reduce exposure or protect the vulnerable service.
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: Apply a compensating control such as restricting access to trusted source IPs and disabling nonessential remote access features — When a critical vulnerability cannot be patched immediately, the best short-term response is to reduce exposure with a compensating control. Restricting access to trusted IPs, disabling unnecessary features, or otherwise narrowing the attack surface buys time until the maintenance window. This is the most practical and least disruptive way to lower risk while preserving the service. Vulnerability management is not only about patching; it is also about managing exposure until remediation is possible. Why others are wrong: B accepts unnecessary risk. C removes useful telemetry and does not address the flaw. D adds visibility but not protection. The key operational principle is to lower exposure as soon as possible when patching is delayed, especially for public-facing systems with known critical issues.
