- A
Change the authentication sequence to use a shorter MFA method like SMS instead of push notifications.
Why wrong: SMS may also experience similar latency or even longer delays; the core issue is the timeout duration, not the method.
- B
Disable MFA for the Asia-Pacific region users temporarily until the MFA provider improves their latency.
Why wrong: This violates the company's MFA requirement and introduces a security risk.
- C
Increase the authentication timeout in the GlobalProtect portal and gateway configuration from 30 seconds to 60 seconds.
Increasing the timeout accommodates the higher latency for users in Asia-Pacific, allowing the MFA push to complete.
- D
Deploy a secondary MFA server instance in the Asia-Pacific region to reduce latency.
Why wrong: This is a significant infrastructure change and may not be feasible or controllable; adjusting the timeout is a simpler and effective solution.
Quick Answer
The correct answer is to increase the authentication timeout in the GlobalProtect portal and gateway configuration from 30 seconds to 60 seconds. This resolves the GlobalProtect MFA timeout due to high latency because the default 30-second window is too short for the round-trip delay between the firewall in a central data center and MFA servers in the United States, especially for users in the Asia-Pacific region who face additional network hops. On the PCNSE exam, this scenario tests your understanding of how authentication sequence timers interact with geographic latency—a common trap is assuming the issue lies with LDAP or MFA provider errors, when the logs show no such failures. Remember that the authentication timeout applies to the entire sequence, not just the MFA push itself, so increasing it is a simple configuration fix without changing the authentication method. A useful memory tip: "30 seconds is for local, 60 seconds for global latency."
PCNSE Practice Question: Securing Users and Applications with Authentication
This PCNSE practice question tests your understanding of securing users and applications with authentication. 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.
You are a network security engineer for a multinational corporation with users in different regions. The company uses GlobalProtect for remote access and requires multi-factor authentication (MFA) using a mobile app for all users. Recently, users in the Asia-Pacific region have reported intermittent failures when authenticating via GlobalProtect. The symptoms include: after entering credentials on the GlobalProtect portal, the authentication challenge from the MFA provider times out after 30 seconds, and the user is disconnected. Users in other regions do not experience this issue. The GlobalProtect gateways and portals are configured with Authentication Profile that uses an LDAP server for primary authentication and an MFA vendor as authentication sequence. The MFA provider sends push notifications to users' mobile devices. The firewall logs show no errors related to LDAP or MFA, but the GlobalProtect logs indicate authentication timeouts. The firewall is located in the central data center, and the MFA provider's servers are in the United States. What should you do to resolve this 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
Increase the authentication timeout in the GlobalProtect portal and gateway configuration from 30 seconds to 60 seconds.
Option C is correct because the authentication timeout in the GlobalProtect portal and gateway configuration defaults to 30 seconds, which is insufficient when high latency exists between the firewall (central data center) and the MFA provider's servers (United States). Users in the Asia-Pacific region experience additional network latency, causing the MFA push notification challenge to exceed the 30-second timeout. Increasing the timeout to 60 seconds accommodates this latency without altering the authentication method or requiring additional infrastructure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the issue is with the MFA method or provider latency, leading them to choose option A or D, when in fact the problem is a misconfigured timeout value that is easily adjustable within the GlobalProtect portal and gateway settings.

Detailed technical explanation
How to think about this question
The GlobalProtect authentication timeout is configured under the portal and gateway's 'Authentication Profile' settings, specifically the 'Authentication Timeout' field (default 30 seconds). This timer starts when the authentication challenge is sent to the MFA provider and must complete before the user is disconnected. Network round-trip time (RTT) from Asia-Pacific to the US can exceed 200ms, and when combined with MFA push notification delivery delays (often 5-15 seconds), the total time can easily surpass 30 seconds. Increasing the timeout to 60 seconds is a simple configuration change that does not affect security posture.
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 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.
