The correct answer involves creating an SD-WAN rule that matches traffic and uses a load balancing algorithm like 'sessions', configuring SD-WAN members as the WAN interfaces, and ensuring BGP advertises the prefix via both interfaces. This works because SD-WAN load balancing distributes inbound traffic across multiple links based on the algorithm selected, while BGP advertisement must originate from each interface to allow the ISP to send traffic over both paths; SD-WAN itself does not advertise routes but influences how traffic is forwarded once received. On the Fortinet NSE 7 Advanced Security NSE7 exam, this scenario tests your understanding of the separation between BGP route advertisement and SD-WAN policy-based load balancing—a common trap is assuming SD-WAN can advertise prefixes, when in fact BGP configuration on each member interface is required. Remember the mnemonic: “BGP shouts, SD-WAN routes”—BGP announces the prefix to the ISP, and SD-WAN decides which link handles each session.
NSE7 Advanced Networking and SD-WAN Practice Question
This NSE7 practice question tests your understanding of advanced networking and sd-wan. 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.
An administrator is configuring BGP on a FortiGate to peer with an ISP router. The FortiGate is advertising a prefix (203.0.113.0/24) to the ISP. To ensure that traffic to the prefix is load balanced across two WAN links (port1 and port2) using SD-WAN, the administrator must configure which THREE of the following? (Select THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Define both port1 and port2 as SD-WAN members
Options A, B, and D are correct. SD-WAN members must be the WAN interfaces. The SD-WAN rule must use a load balancing algorithm (e.g., sessions) to distribute traffic. BGP must advertise the prefix via both interfaces; this is typically done via advertising the prefix through BGP on both members or by using SD-WAN to influence the routing. Actually, BGP advertisement is separate; SD-WAN does not advertise routes. But to load balance inbound traffic, the administrator may need to advertise via both links. However, the question focuses on SD-WAN configuration, so A, B, D are essential.
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.
✓
Define both port1 and port2 as SD-WAN members
Why this is correct
SD-WAN members are the interfaces to be load balanced.

Read the scenario before looking for a memorised answer.
✗
Configure a performance SLA to monitor each link
Why it's wrong here
Performance SLAs are optional for health checks; not required for load balancing.
✓
Enable 'set load-balance-mode' on the SD-WAN rule to 'sessions' or another algorithm
Why this is correct
The load balancing mode must be set to distribute traffic.

✗
Configure BGP to use the same AS number on both members
Why it's wrong here
AS number is typically the same, but not specifically related to load balancing.
✓
Create an SD-WAN rule that matches traffic and uses a load balancing algorithm like 'sessions'
Why this is correct
The rule defines how traffic is distributed across members.

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.

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.

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.
