- A
The SSL/TLS service profile on the gateway.
Why wrong: Incorrect. SSL profile controls web interface encryption, not IPSec data encryption.
- B
The IPSec crypto profile associated with the gateway.
Correct. Crypto profile defines algorithms for data encryption.
- C
The GlobalProtect portal agent configuration.
Why wrong: Incorrect. Portal agent handles client software settings, not encryption algorithms.
- D
The SSL/SSH service profile on the firewall.
Why wrong: Incorrect. This profile controls management access encryption.
Question 252 of 516
IPsec Crypto Profile for GlobalProtect Encryption — Configuring Strong Algorithms | Palo Alto Networks Certified Network Security Explained
This PCNSE practice question tests your understanding of secure access and vpn. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
During a security audit, it is discovered that the GlobalProtect gateway allows clients to use weak encryption algorithms. Which configuration object controls this?
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
✓
The IPSec crypto profile associated with the gateway.
The GlobalProtect gateway uses IPSec to secure VPN tunnels between clients and the gateway. The IPSec crypto profile defines the encryption algorithms, authentication methods, and key exchange parameters for these tunnels. If weak encryption algorithms are allowed, it is because the IPSec crypto profile associated with the gateway is configured with those weak options.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 SSL/TLS service profile on the gateway.
- ✓
The IPSec crypto profile associated with the gateway.
Why this is correct
Correct. Crypto profile defines algorithms for data encryption.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The GlobalProtect portal agent configuration.
Why it's wrong here
Incorrect. Portal agent handles client software settings, not encryption algorithms.
- ✗
The SSL/SSH service profile on the firewall.
Why it's wrong here
Incorrect. This profile controls management access encryption.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the SSL/TLS service profile (used for portal/management encryption) with the IPSec crypto profile (which actually controls the VPN tunnel encryption between GlobalProtect clients and the gateway).
Detailed technical explanation
How to think about this question
The IPSec crypto profile in PAN-OS specifies IKE phase 1 and phase 2 parameters, including encryption (e.g., AES-128-CBC, 3DES), authentication (e.g., SHA-1, SHA-256), and Diffie-Hellman groups. Weak algorithms like 3DES or SHA-1 are often left enabled for backward compatibility, but they can be disabled by editing the crypto profile. In a real-world audit, you would check the 'IKE Crypto Profile' and 'IPSec Crypto Profile' assigned to the gateway's tunnel interface to identify weak ciphers.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PCNSE exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
Quick reference
VPN Protocol Comparison
| Protocol | Port | Encryption | Authentication | Use Case |
|---|---|---|---|---|
| IKEv2 / IPsec | UDP 500 / 4500 | AES-256 | Certificates / PSK | Site-to-site & remote access |
| SSL / TLS VPN | TCP 443 | TLS 1.3 | Certificates / MFA | Clientless remote access |
| L2TP / IPsec | UDP 1701 | AES (IPsec) | PSK / Certificates | Legacy remote access |
| WireGuard | UDP 51820 | ChaCha20 | Public keys | Modern high-performance VPN |
| PPTP | TCP 1723 | MPPE (weak) | MS-CHAPv2 | Legacy — avoid in production |
PPTP is considered insecure. IKEv2/IPsec and SSL VPN are the current recommended options.
