- A
There is a deny rule placed above the new Admin rule that matches the Admin zone traffic.
Correct. A deny rule above would block the SSH traffic before it reaches the allow rule.
- B
The Admin rule has a typo in the destination address, causing it to not match the server.
Why wrong: Incorrect. If the destination address were wrong, the rule would not match at all, but the traffic would then fall through to the Management rule (which allows), so it would not be denied.
- C
The Management rule is shadowing the Admin rule due to overlapping conditions.
Why wrong: Incorrect. Shadowing implies the Management rule would match first, but since Admin rule is above, it should match first. Denial indicates a deny rule above.
- D
The Admin zone is not associated with the correct virtual router.
Why wrong: Incorrect. If the zone were misconfigured, the traffic would not match the rule at all, but it would not be explicitly denied.
PCNSA Policy Evaluation and Management Practice Question
This PCNSA practice question tests your understanding of policy evaluation and management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator has configured multiple security rules for a data center. There is a rule that allows SSH from the 'Management' zone to the 'Server' zone. Recently, the administrator added a new rule allowing SSH from a new 'Admin' zone to the 'Server' zone. The Admin rule is placed above the Management rule. Both rules specify the correct zones, application SSH, and action allow. After committing, SSH traffic from the Admin zone is being denied. What is the most likely issue?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
There is a deny rule placed above the new Admin rule that matches the Admin zone traffic.
If the Admin rule is above the Management rule and both allow SSH, traffic should be allowed. The only plausible reason for denial is that a deny rule exists above the Admin rule that matches the Admin zone traffic. Option B correctly identifies this.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
There is a deny rule placed above the new Admin rule that matches the Admin zone traffic.
- ✗
The Admin rule has a typo in the destination address, causing it to not match the server.
Why it's wrong here
Incorrect. If the destination address were wrong, the rule would not match at all, but the traffic would then fall through to the Management rule (which allows), so it would not be denied.
- ✗
The Management rule is shadowing the Admin rule due to overlapping conditions.
Why it's wrong here
Incorrect. Shadowing implies the Management rule would match first, but since Admin rule is above, it should match first. Denial indicates a deny rule above.
- ✗
The Admin zone is not associated with the correct virtual router.
Why it's wrong here
Incorrect. If the zone were misconfigured, the traffic would not match the rule at all, but it would not be explicitly denied.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCNSA NAT questions on configuration and troubleshooting.
