Q: 7
A QoS policy on Cisco UCS must meet mese requirements:
No-drop class must be configured
Jumbo frames must be enabled without fragmentation.
Which configuration must be implemented to meet mese conditions?

C/D? From what I remember, the QoS system class is used for no-drop configs in UCS, and you need to set MTU to 9216 for true jumbo frames. Option D lines up with that and matches what I've seen on official docs. Think that's the way to go but if anyone disagrees let me know. Official guide plus hands-on lab helps a lot here.
Option A official guide and labs usually help with these UCS QoS cases, at least in practice exams.
D is correct. No-drop requires a QoS system class with the largest MTU, not just the platinum class. Platinum can be tempting but doesn't guarantee no packet loss for jumbo frames. Pretty sure that's what the exam expects, but shout if you disagree.
I would've tried A since Platinum System class lets you set the MTU to 9100.
D need QoS system class and max MTU for no-drop and jumbo frames. Anyone disagree?
D for sure. Only the QoS system class lets you do no-drop and set MTU 9216 for jumbo frames on UCS.
I don’t think it’s D. A looks better since the Platinum System class is designed for high priority/no-drop traffic and setting MTU to 9100 bytes covers jumbo frames. The question doesn’t say you need max MTU (9216), just that fragmentation isn’t allowed with jumbo, so 9100 should work. Unless there’s something specific about system class vs platinum that I’m missing?
I'd pick A here. Platinum class with MTU 9100 should handle jumbo frames and maintain no-drop for traffic in most UCS setups. Might be missing something subtle though, open to corrections.
D tbh. Platinum system class (A) is a common trap since people link it to high priority, but for true no-drop and jumbo frame support you need QoS system class with max MTU. Seen similar in practice sets.
A , Platinum with 9100 MTU seems right for jumbo and no-drop in some UCS setups.
Be respectful. No spam.
