The answer is to execute 'execute ha synchronize start' from the primary unit. This is correct because a checksum mismatch between cluster members indicates configuration drift, where the secondary unit’s system and router objects have diverged from the primary. The first step in any HA checksum mismatch resolution must be to force a full configuration synchronization from the authoritative primary, as this re-establishes consistency before any deeper debugging. On the Fortinet NSE 7 Advanced Security exam, this scenario tests your understanding of HA state synchronization and the proper escalation path—many candidates mistakenly jump to debug logs or reboot the secondary, but the exam emphasizes that synchronization is the prerequisite. A common trap is assuming a checksum mismatch always means corruption; in reality, it often stems from a failed sync or manual changes on the secondary. Memory tip: think “Sync First, Debug Later”—always run the synchronize command before investigating individual object differences.
NSE7 Troubleshooting and Diagnostics Practice Question
This NSE7 practice question tests your understanding of troubleshooting 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.
Two FortiGate units in an HA cluster are experiencing synchronization issues. The administrator runs 'diagnose sys ha checksum cluster' and sees different checksum values for the 'system' and 'router' objects. What is the FIRST step to resolve the mismatch?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Execute 'execute ha synchronize start' from the primary unit
Option B is correct. The checksum mismatch indicates configuration drift. The first step should be to synchronize the configuration from the primary unit to the secondary using 'execute ha synchronize start'.
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.
✓
Execute 'execute ha synchronize start' from the primary unit
Why this is correct
This command forces configuration synchronization from primary to secondary.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Upgrade the firmware on both units to the same version
Why it's wrong here
If firmware versions were different, HA would not form. The mismatch is in configuration, not firmware.
✗
Reboot both units to force a full sync
Why it's wrong here
Rebooting is disruptive and not the first step; manual sync should be attempted first.
✗
Disable and re-enable HA on both units
Why it's wrong here
This would cause downtime; manual sync is less disruptive.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
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.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.

Use explanations to understand the rule behind the answer.
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 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.
