Palo Alto Networks NetSec-Analyst Practice Test 40
Question 390
A network security analyst needs exactly TWO case-specific control steps. An administrator expands outbound source NAT to a new sales subnet, but return traffic intermittently fails under an undersized translated port pool. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.
- Collect evidence: Examine NAT pool utilization, translation errors, concurrent sessions and policy match for peak sales load.
- Alternative diagnostic: Review pre/post-translation addresses, routes, Security rule zones and return-session logs.
- Apply correction: Review dynamic IP-and-port translation resource sizing and split eligible source networks or enlarge the approved pool.
- Competing correction: Use dynamic IP and port source NAT on the permitted egress flow with the approved public interface/address pool.
- Alternative verification: External test connections to the public service reach the intended internal support endpoint and are logged.
Explanation
Correct Answer
A:Success is demonstrated when: Peak test sessions obtain successful translations and return traffic without port-allocation exhaustion. Source NAT capacity and session translation resources must be sufficient for simultaneous client conversations.
C:The expected outcome is: Peak test sessions obtain successful translations and return traffic without port-allocation exhaustion. Source NAT capacity and session translation resources must be sufficient for simultaneous client conversations.
Incorrect Answers
B:This corresponds to a different condition: A merger introduces two networks with overlapping RFC1918 subnets, breaking a specific partner-service route. Alternative diagnostic: Review pre/post-translation addresses, routes, Security rule zones and return-session logs.
D:This corresponds to a different condition: A branch has hundreds of private clients sharing one public egress IP and static one-to-one translations would exhaust its pool. Competing correction: Use dynamic IP and port source NAT on the permitted egress flow with the approved public interface/address pool.
E:This corresponds to a different condition: A company publishes an internal support server at a public address, but users reach the firewall and not the server. Alternative verification: External test connections to the public service reach the intended internal support endpoint and are logged.
Question 391
A campus introduces SSL forward proxy for employee web traffic and wants known HTTPS application malware inspected. The team is considering the shortcut: Enable a decrypt rule without deploying trust to endpoints and ignore certificate errors. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.
- Enable a decrypt rule without deploying trust to endpoints and ignore certificate errors.
- Narrowly exclude the technically incompatible destination through the documented SSL decryption exclusion workflow.
- Use SSL Inbound Inspection only when the server certificate/private key and platform prerequisites are available and approved.
- Create a narrowly scoped SSL Forward Proxy decryption policy using an appropriate forward-trust certificate and matching profile.
Explanation
Correct Answer
D:Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection. This correction targets the observed gap rather than a neighboring symptom.
Incorrect Answers
A:That option would enable a decrypt rule without deploying trust to endpoints and ignore certificate errors, but it addresses a different concern. This correction targets the observed gap rather than a neighboring symptom.
B:This corresponds to a different condition: A payment provider's certificate-pinned mobile application fails under a broad decrypt rule. The current report has a distinct control gap; Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection.
C:This corresponds to a different condition: A published internal HTTPS service is behind an NGFW and security requests inbound TLS inspection with access to the server key material. The current report has a distinct control gap; Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection.
Question 392
In a Palo Alto Networks configuration review, the following condition is reported: A campus introduces SSL forward proxy for employee web traffic and wants known HTTPS application malware inspected. The proposed correction is to create a narrowly scoped SSL Forward Proxy decryption policy using an appropriate forward-trust certificate and matching profile. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.
- Inbound SSL inspection differs from outbound forward proxy: the firewall needs the protected server's key and suitable certificate settings.
- Certificate pinning can prevent man-in-the-middle forward-proxy inspection, requiring a documented technical exception.
- Privacy and compliance exclusions should be narrow and explicit rather than a blanket disablement of TLS safeguards.
- Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection.
Explanation
Correct Answer
D:The validation result should be: Permitted controlled HTTPS sessions are decrypted where authorized and inspected by applicable Security profiles.
Incorrect Answers
A:This corresponds to a different condition: A published internal HTTPS service is behind an NGFW and security requests inbound TLS inspection with access to the server key material. The directly relevant correction here is: Create a narrowly scoped SSL Forward Proxy decryption policy using an appropriate forward-trust certificate and matching profile.
B:This corresponds to a different condition: A payment provider's certificate-pinned mobile application fails under a broad decrypt rule. The directly relevant correction here is: Create a narrowly scoped SSL Forward Proxy decryption policy using an appropriate forward-trust certificate and matching profile.
C:This corresponds to a different condition: A privacy policy prohibits decrypting employee access to a narrowly defined counseling service, but the default decrypt rule matches it. The current report has a distinct control gap; Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection.
Question 393
An analyst must collect precise technical evidence before changing configuration. A campus introduces SSL forward proxy for employee web traffic and wants known HTTPS application malware inspected. Which investigation would BEST isolate this specific mismatch? Select ONE best answer.
- Verify the protected server certificate/key availability, relevant decryption rule and inbound handshake logs.
- Inspect user and URL category matches, decryption rule order, certificate-status policy and privacy approval.
- Correlate handshake failures and app destination with the decryption logs and exclusion inventory.
- Check trusted issuing certificate deployment, decryption rule match, TLS handshake and decrypted session logs.
Explanation
Correct Answer
D:Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection. These checks distinguish the actual cause before changes are attempted.

Question 395
A supervisor is assessing the risks of a rushed remediation. A campus introduces SSL forward proxy for employee web traffic and wants known HTTPS application malware inspected. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.
- Create a narrowly scoped SSL Forward Proxy decryption policy using an appropriate forward-trust certificate and matching profile.
- Enable a decrypt rule without deploying trust to endpoints and ignore certificate errors.
- Check trusted issuing certificate deployment, decryption rule match, TLS handshake and decrypted session logs.
- Permitted controlled HTTPS sessions are decrypted where authorized and inspected by applicable Security profiles.
Explanation
Correct Answer
B:This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The required principle is: Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection.
Incorrect Answers
A:This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Enable a decrypt rule without deploying trust to endpoints and ignore certificate errors.
C:This is a controlled and useful step for the described condition, not the unsafe shortcut. Forward-proxy decryption requires a trusted subordinate certificate chain, relevant rule match and compliance scope for inspection.
D:This is a controlled and useful step for the described condition, not the unsafe shortcut. Permitted controlled HTTPS sessions are decrypted where authorized and inspected by applicable Security profiles.
