The answer is to enable 'set load-balance-schedule' on the HA interface. This configuration is correct because it allows the active-passive HA cluster to selectively distribute new sessions for specific services across both FortiGate units, while preserving the core failover behavior for all other traffic. In a standard active-passive setup, only the primary unit handles traffic, but by applying a load-balance schedule, the administrator defines which services should be load-balanced, effectively creating a hybrid model that optimizes resource use without compromising high availability. On the Fortinet NSE 4 Network Security Professional NSE4 exam, this concept tests your understanding of HA load balancing versus simple failover, and a common trap is confusing this with a full active-active configuration or assuming load balancing requires disabling failover. Remember the memory tip: "Schedule the balance, keep the failover"—the schedule keyword is your clue that you are selectively distributing new connections while retaining active-passive redundancy.
NSE4 High Availability and Diagnostics Practice Question
This NSE4 practice question tests your understanding of high availability and diagnostics. 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.
In an active-passive HA cluster, the administrator wants to ensure that new connections are load-balanced across both units only for specific services while maintaining failover capability. Which configuration should be applied?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable 'set load-balance-schedule' on the HA interface
Option B is correct. Load balancing in HA is achieved by enabling 'load-balance-schedule' on the HA interface. This allows distributing new sessions across cluster units while retaining active-passive failover behavior.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

TExam Day Tips
→Underline the problem statement mentally.
→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 NSE4 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.
