Q: 18
Refer to the exhibit. 
Refer to the exhibit. Customers report low video quality and delays when having point-to-point telepresence video calls between the two locations. An architect must optimize a design so that traffic follows the same path for egress and ingress traffic flows. Which technique optimizes the design?

Looks like C is best. Official guide and practice lab questions cover OSPF metrics and path selection pretty well.

C, setting a high metric in area 4 makes both directions prefer the same link. That should help keep the traffic symmetric, which is key for stable video calls. Pretty sure that's what they're after.
Why do they keep tossing in these OSPF metric tuning questions? C, set a high metric on area 4.
I'm not sure if C is right. I think route leaking on the router in area 2 would better control path selection for the return traffic, so I'd pick A here.
Hmm, not convinced C is right for keeping traffic symmetric. I'd say route leaking in area 2 (A) is closer since it can help manage return path selection, but could be a trap if not careful.
Be respectful. No spam.
