E is definitely true, you need to configure for expedited traffic.

C is spot on, H1 does get its CIR first.

Wait, are orphaned queues really scheduled out of BE? Sounds odd!

I think B is misleading, it doesn't always spend equal time.

A is true, 8 priority levels are correct.

I’m leaning towards option E being true because I remember something about needing to configure queues for expedited forwarding, but I’m not 100% certain.

I’m a bit confused about option C; I feel like I read something about forwarding classes, but I can’t recall the details.

I remember practicing a question about queue servicing, and I think option B might be correct since it mentions equal time for queues with traffic.

I think option A sounds familiar, but I’m not entirely sure about the specifics of the round-robin algorithm.

Ah, this is right in my wheelhouse. I'm confident I can identify the two true statements about the default scheduler on the Alcatel-Lucent 7750 SR.

Whoa, this is a lot of information to digest. I better take my time and make sure I understand the nuances of the default scheduler behavior before selecting the correct answers.

Okay, I think I've got a handle on this. The key is understanding the default queue servicing model and how the different forwarding classes are treated.

Hmm, I'm a bit unsure about the details of the default scheduler on this platform. I'll need to refresh my memory on the number of priority levels and the scheduling algorithm used.

This looks like a tricky question on the default scheduler behavior in the Alcatel-Lucent 7750 SR. I'll need to carefully review the options and think through the key scheduler characteristics.

I'm pretty sure A is right. The 7750 SR has 8 priority levels serviced using round-robin.
JO

Yes, A is one of the correct statements. The scheduler uses round-robin for servicing.
JO

I agree, A is correct. The default scheduler has 8 priority levels.
WI

Haha, orphaned queues in the BE queue - that's a funny one! But I agree, D is incorrect.
RE

Definitely B is wrong. The default scheduler doesn't spend equal time in each queue, it's based on priority levels.
SH

C and E seem to be the correct answers here. The H1 class gets prioritized over AF traffic, and expedited queues need explicit configuration.
LO

No problem, happy to help clarify things.
CE

That's good to know, thanks for pointing that out.
BU

So the H1 class gets its CIR before AF traffic, and expedited queues need explicit configuration.
LE
Leoma

I think you're right, C and E are the correct answers.
KA
Kathrine

I'm not sure about C and D, but I think E is definitely true. Explicit configuration is needed for EF and AF traffic.
AM

I agree with you, Leila. The round-robin algorithm and equal time in each queue make sense.
LE
Leila

I think A and B are true about the default scheduler.
