Quick Answer
The answer is to enable set session-pickup under config system ha. This command is essential for HA session synchronization on FortiGate because it instructs the cluster to continuously replicate the state of all active sessions from the primary unit to the backup units. Without this setting, after a failover, the new primary unit has no record of the existing connections, causing established sessions to drop and requiring clients to re-establish their traffic. On the Fortinet NSE 7 Advanced Security NSE7 exam, this concept tests your understanding of high availability session management, often appearing as a distractor where candidates confuse session-pickup with failover order or priority settings. A common trap is assuming session synchronization happens automatically; it does not—it must be explicitly enabled. Remember the mnemonic “Pick up the sessions to keep them alive” to recall that session-pickup is the key to seamless failover.
This NSE7 practice question tests your understanding of troubleshooting and diagnostics. 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.
In an HA cluster, after a failover, some established sessions are not being synchronized to the new primary unit. Which setting must be enabled to ensure session synchronization?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
set override enable
Why wrong: Override enables preemptive failback, not session sync.
set sync-sessions enable
Why wrong: This command does not exist; correct command is session-pickup.
set priority <value>
Why wrong: Priority sets the device priority, not session sync.
set session-pickup enable
This enables session synchronization in HA.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
set session-pickup enable
Option B is correct because 'set session-pickup enable' under config system ha enables session synchronization between HA members. Option A controls failover order. Option C is for priority. Option D is not a valid setting.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
set override enable
Why it's wrong here
Override enables preemptive failback, not session sync.
set sync-sessions enable
Why it's wrong here
This command does not exist; correct command is session-pickup.
set priority <value>
Why it's wrong here
Priority sets the device priority, not session sync.
set session-pickup enable
Why this is correct
This enables session synchronization in HA.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
This command does not exist; correct command is session-pickup.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the NSE7 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.
