The correct answer is that SD-WAN rules can use BGP attributes such as AS path to influence path selection, because BGP learned routes are treated as SD-WAN members, allowing their attributes to directly shape traffic steering and load balancing decisions within the FortiGate SD-WAN fabric. This integration works by mapping BGP path attributes—like AS path length, local preference, or MED—into SD-WAN rule criteria, enabling dynamic, policy-based routing without static overrides. On the Fortinet NSE 7 Advanced Security NSE7 exam, this concept tests your understanding of how BGP and SD-WAN converge to optimize WAN edge performance, often appearing in scenario-based questions where you must distinguish between route redistribution and attribute-based rule matching. A common trap is assuming BGP only influences routing tables, not SD-WAN path selection rules. Memory tip: think of BGP attributes as the “votes” that SD-WAN rules count to pick the best path.
NSE7 Advanced Networking and SD-WAN Practice Question
This NSE7 practice question tests your understanding of advanced networking and sd-wan. 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.
An administrator is configuring BGP with SD-WAN on a FortiGate. Which TWO statements are true about BGP and SD-WAN integration? (Choose two.)
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
BGP learned routes can be used as SD-WAN members and can influence path selection based on attributes like AS path. SD-WAN rules can use BGP attributes for load balancing.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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
Static NAT maps one inside address to one outside address.
✗
BGP route redistribution is not supported with SD-WAN
Why it's wrong here
It is supported.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related NSE7 NAT questions on configuration and troubleshooting.
