Free Cisco 300-425 ENWLSD Actual Exam Questions - Question 4 Discussion
the 5 GHz band set to 40 MHz. Co-channel interference must be reduced. Which two actions must be
taken? (Choose two.)
D/E? Dropping to 20 MHz channels in 5 GHz definitely shrinks the interference footprint, and lowering AP power helps limit overlapping coverage areas, which cuts down co-channel issues. Increasing SSIDs or changing 2.4 GHz settings feels unrelated since the question focuses on 5 GHz and interference reduction specifically. Disabling band steering doesn't really help with co-channel interference either. So D and E make the most sense based on the given details.
Maybe E and D. Lowering AP power limits overlap zones, and 20 MHz channels in 5 GHz reduce co-channel interference without cramming too many networks in the same spectrum. Increasing SSIDs or 2.4 GHz settings doesn’t help here.
Maybe D and E. Dropping channel width to 20 MHz in 5 GHz definitely cuts overlap, and lowering power reduces signal spill, which helps with co-channel interference in open areas. Seems logical here.
I'm thinking D and E. Using 20 MHz channels in 5 GHz reduces overlap, cutting co-channel interference. Also, lowering AP power helps limit interference range in open spaces. Anyone else agree or see a better combo?
