Full question →mediummultiple choiceObjective-mapped
A critical vulnerability is discovered on an internet-facing VPN appliance that cannot be patched for six weeks because the vendor has not released a fix. The VPN service must remain available. What is the best operational response?
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
Leave the appliance unchanged until the vendor releases a patch.
Doing nothing leaves a known, exposed weakness in place and ignores immediate risk reduction opportunities.
B
Best answer
Apply compensating controls such as restricting source IPs and increasing monitoring.
When a patch is unavailable, risk should be reduced through compensating controls. Limiting who can reach the VPN and closely monitoring access attempts lowers exposure while maintaining service availability until remediation is possible.
C
Distractor review
Disable all logging so the appliance performs better under load.
Turning off logs would remove visibility during a high-risk period and make incident detection much harder.
D
Distractor review
Replace the VPN with a less secure remote access method to avoid the vulnerability.
Switching to a weaker remote access design increases risk and does not address the original exposure in a secure way.
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 compensating controls such as restricting source IPs and increasing monitoring. — The correct response is to use compensating controls while the vendor fix is unavailable. Restricting source IPs, tightening firewall rules, enabling heightened alerting, and reviewing authentication activity all reduce exposure without taking the service offline. Vulnerability management is not only about patching; it also includes documented risk reduction when immediate remediation is impossible. Why others are wrong: Leaving the appliance unchanged accepts a known critical exposure for weeks. Disabling logging removes the visibility needed to detect exploitation attempts. Replacing the VPN with a weaker method reduces security instead of improving it, which is not an acceptable compensating strategy.
