NSE7 Advanced Networking and SD-WAN Practice Question
An administrator is configuring BGP with SD-WAN on a FortiGate. Which TWO statements are true about BGP and SD-WAN integration? (Choose two.)
⚠ Common exam trap
A common mix-up: candidates assume BGP always dictates the forwarding path in an SD-WAN setup, but FortiGate's SD-WAN rules can override BGP best path selection based on performance SLA metrics.
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
✓
SD-WAN performance SLA can override BGP best path selection
SD-WAN performance SLA rules can override BGP best path selection by steering traffic over a different SD-WAN member interface, even if BGP would have chosen a different path. This is achieved through SD-WAN rules that match traffic and apply an action like 'best quality' or 'lowest cost', which takes precedence over the BGP routing table decision.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
BGP must be disabled on interfaces used for SD-WAN
Why it's wrong here
BGP can run on SD-WAN members.
- ✗
BGP learned routes cannot be used as SD-WAN members
Why it's wrong here
They can be used as members.
- ✓
SD-WAN performance SLA can override BGP best path selection
Why this is correct
SD-WAN can choose a different path based on SLA metrics.
- ✓
SD-WAN rules can use BGP attributes such as AS path to influence path selection
Why this is correct
Yes, SD-WAN can consider BGP attributes.
- ✗
BGP route redistribution is not supported with SD-WAN
Why it's wrong here
It is supported.
