Nokia 4A0-C02 Exam - Topic 4 Question 14 Discussion

Actual exam question for Nokia's 4A0-C02 exam

Question #: 14
Topic #: 4

A queue is configured with the following attributes:

MBS = 10KB

CBS = 5KB

High-Priority-Only = 30%

Assume that there is no CBS overbooking and that the slope-policy is disabled. If the current queue depth is 8KB, what will happen to an in-profile packet arriving in the queue?

AIt will be discarded because the high-priority-only threshold is exceeded.

BIt will be queued but re-marked as 'out-of-profile.'

CIt will be queued in the reserved portion of the buffer pool and remain 'in-profile.'

DIt will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.

EIt will be queued in the shared portion of the buffer pool but may be dropped if the buffer utilization exceeds the start-average value of the low slope.

I’m surprised it doesn’t just get dropped!

Wait, how does the high-priority-only threshold affect this?

I think it gets re-marked as 'out-of-profile.'

It's 8KB, so it won't be discarded.

I think the packet should be queued in the reserved portion since it's in-profile, but I'm a bit confused about the high-priority-only setting.

This question feels similar to one we practiced where the queue depth was different. I think if the packet is in-profile, it might still get queued, but I can't recall the exact details.

I remember that the high-priority-only threshold is crucial, but I'm not sure how it interacts with the current queue depth.

I feel like the shared buffer pool option might be the right answer, but I’m not entirely sure if it applies here since the queue depth is already at 8KB.

Ah, I remember now! The bitwise shift operators are << and >>. Easy peasy, I've got this.

I'm not totally confident on this one. I'll need to review the SIP protocol details to make sure I select the right answer.

My gut says A and B might be correct, since we always checked those areas in our training drills.

Okay, let's see. Aboot is the first file to boot, so I'm going to go with option B.

I remember that the Storage Maintenance Window pattern is crucial for preventing data loss during outages, but I'm confused about how it interacts with the other patterns mentioned.
