An IDS signature fires on outbound traffic but analysts suspect a false positive. Which validation steps are appropriate? (Choose 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
Distractor review
Assume all signatures are always correct
Signatures can be noisy and need validation.
B
Best answer
Check whether the destination and application protocol match the rule intent
Protocol and destination context help identify misfired signatures.
C
Distractor review
Disable every IDS rule from the same vendor
Broad disabling removes unrelated coverage.
D
Best answer
Inspect packet payload or session metadata around the alert
Traffic context can confirm whether the signature matched meaningful exploit content.
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 CS0-003 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Check whether the destination and application protocol match the rule intent — IDS validation requires packet/session context and rule-intent review.
