Fortinet NSE8_812 Exam - Topic 3 Question 38 Discussion

Actual exam question for Fortinet's NSE8_812 exam

Question #: 38
Topic #: 3

Refer to the exhibit, which shows a Branch1 configuration and routing table.

In the SD-WAN implicit rule, you do not want the traffic load balance for the overlay interface when all members are available.

In this scenario, which configuration change will meet this requirement?

AChange the load-balance-mode to source-ip-based.

BCreate a new static route with the internet sdwan-zone only

CConfigure the cost in each overlay member to 10.

DConfigure the priority in each overlay member to 10.

Show Suggested Answer

Suggested Answer: D

The default load balancing mode for the SD-WAN implicit rule is source IP based. This means that traffic will be load balanced evenly between the overlay members, regardless of the member's priority.

To prevent traffic from being load balanced, you can configure the priority of each overlay member to 10. This will make the member ineligible for load balancing.

The other options are not correct. Changing the load balancing mode to source-IP based will still result in traffic being load balanced. Creating a new static route with the internet sdwan-zone only will not affect the load balancing of the overlay interface. Configuring the cost in each overlay member to 10 will also not affect the load balancing, as the cost is only used when the implicit rule cannot find a match for the destination IP address.

C sounds interesting, but I doubt it would solve the issue.

B could work too, but not sure if it's the best choice.

Wait, why would you change the load-balance mode? Seems risky.

Definitely agree with A, makes sense!

I’m leaning towards option D, but I’m not confident. I remember something about priorities impacting traffic flow in SD-WAN setups.

I feel like configuring costs might be the way to go, but I can't recall if that directly affects load balancing in this context.

I think we practiced a similar question where changing the priority helped with traffic management. Could that apply here too?

I remember discussing load balancing modes in class, but I'm not entirely sure if source-ip-based is the right choice here.

I'm pretty confident that Option A is the correct answer. Changing the load-balance-mode to source-ip-based should ensure that traffic is not load balanced when all overlay members are available, which is what the question is asking for.

Okay, let me think this through step-by-step. The question is asking for a configuration change to meet the requirement, so I'm going to focus on the options provided. Option B doesn't seem relevant, and Option C and D both involve setting the cost/priority, which may not be the right approach here.

Hmm, I'm a bit confused by the wording of the question. Does "you do not want the traffic load balance for the overlay interface when all members are available" mean we need to disable load balancing completely, or just in a specific scenario? I'll need to re-read the question carefully.

I think the key here is to understand the SD-WAN implicit rule and how it relates to load balancing. Option A seems like a good approach to address the requirement of not wanting traffic load balance when all members are available.

I'm going with D. Prioritizing the overlay members equally is the simplest and most straightforward way to meet the requirement.

Hmm, that makes sense too. It could ensure that the traffic load balance is not done when all members are available.

I disagree, I believe the correct answer is D) Configure the priority in each overlay member to 10.

Haha, I bet the exam writer had a good chuckle coming up with these options. Option B is just plain silly, who would create a static route just for the internet zone?
