PCNSA Policy Evaluation and Management Practice Question
This PCNSA practice question tests your understanding of policy evaluation and management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Exhibit
set security policies policy-name Allow-Sales-to-Finance
from Sales
to Finance
source any
destination 10.10.10.0/24
application ms-office365
action allow
log-start yes
set security policies policy-name Deny-Other
from Sales
to Finance
source any
destination any
application any
action deny
log-end yes
Refer to the exhibit. Traffic from Sales zone to Finance zone reaches destination 10.10.10.10 using application 'ssl'. What action does the firewall take?

A
The firewall will continue to the next rule
Why wrong: There is no next rule; the second rule is the last and matches any application.
B
Allow
Why wrong: The first rule only allows ms-office365, not ssl.
C
Deny
Traffic does not match the first rule (application mismatch), so it matches the second rule and is denied.
D
Allow only if no security profile blocks it
Why wrong: The deny rule will block regardless of security profiles.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deny
Option A is correct because the first rule only matches 'ms-office365' application; 'ssl' does not match, so it goes to the second rule which denies any application. Option B is wrong because the first rule does not allow ssl. Option C is wrong because the deny rule will block it. Option D is wrong because the firewall does not need more rules; it has a deny all rule.
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.
✗
The firewall will continue to the next rule
Why it's wrong here
There is no next rule; the second rule is the last and matches any application.
Traffic does not match the first rule (application mismatch), so it matches the second rule and is denied.
Related concept
Static NAT maps one inside address to one outside address.
✗
Allow only if no security profile blocks it
Why it's wrong here
The deny rule will block regardless of security profiles.
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.
Policy Evaluation and Management — This question tests Policy Evaluation and Management — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Deny — Option A is correct because the first rule only matches 'ms-office365' application; 'ssl' does not match, so it goes to the second rule which denies any application. Option B is wrong because the first rule does not allow ssl. Option C is wrong because the deny rule will block it. Option D is wrong because the firewall does not need more rules; it has a deny all rule.
What should I do if I get this PCNSA question wrong?
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.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
