Q: 3
An architect must address sustained congestion on the access and distribution uplink of network.
QoS has already been implemented and optimized, but it is no longer effective in ensuring optimal
network performance. Which two solutions should the architect use to improver network
performance? (Choose two)

B E imo. C and D might look tempting but if QoS is already maxed, adding more bandwidth isn't always possible in the scenario. B and E work to better manage congestion left over. Anyone see this on a recent practice?
B tbh
Interesting take, but I gotta say B and E. With QoS maxed out, managing drops using RED and selective discard makes sense here. Not 100% but leaning that way.
Pretty sure it's B and E. Had something like this in a mock, where after QoS is fully optimized and congestion's still an issue, solutions like RED (B) and selective packet discard (E) are more about managing which traffic gets dropped gracefully. C and D would be ideal if physical upgrades are possible but the scenario hints those aren't options here. Agree?
C or D, honestly. In real practice, adding uplinks (C/D) tends to solve congestion outright compared to just tweaking packet drop methods like B/E. Maybe B is a distractor since RED helps in some cases, but not when links are maxed out.
B E
B imo and E. D looks like a trap since the question focuses on congestion when QoS is already tuned.
Option B and E. D’s tempting but exam guides usually call out RED and selective discard for this exact situation.
I think C and D since adding more uplinks or increasing speed should help more in this scenario.
C/D? If QoS is maxed out, usually the next step is to increase physical bandwidth, so higher-speed uplinks or EtherChannel aggregation (C and D). B sounds like a trap since RED doesn’t fix sustained congestion. Disagree?
Be respectful. No spam.
