NSE7 Advanced Networking and SD-WAN Practice Question
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.)
⚠ Common exam trap
Candidates often confuse performance SLA monitoring (which is for failover and link quality) with load balancing, or they incorrectly assume BGP AS number configuration affects SD-WAN load balancing, when in fact SD-WAN operates independently of BGP AS numbering.
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
✓
Define both port1 and port2 as SD-WAN members
SD-WAN load balancing requires that both WAN interfaces (port1 and port2) are defined as SD-WAN members. Without adding them to the SD-WAN zone, the FortiGate cannot distribute traffic across them using SD-WAN rules or load-balancing algorithms.
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.
- ✗
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.
