Oracle 1Z0-1110-25 Exam - Topic 2 Question 15 Discussion

Actual exam question for Oracle's 1Z0-1110-25 exam

Question #: 15
Topic #: 2

You have an image classification model in the model catalog which is deployed as an HTTP endpoint using model deployments. Your tenancy administrator is seeing increased demands and has asked you to increase the load balancing bandwidth from the default of 10Mbps. You are provided with the following information:

Payload size in KB = 1024

Estimated requests per second = 120 requests/second (Monday through Friday, in every month, in every year)

Buffer percentage = 20%What is the optimal load balancing bandwidth to redeploy your model?

A452 Mbps

B52 Mbps

C7052 Mbps

D1152 Mbps

Show Suggested Answer

Suggested Answer: D

Detailed Answer in Step-by-Step Solution:

Objective: Calculate optimal bandwidth for model deployment.

Given Data:

Payload size = 1024 KB = 1024 * 8 = 8192 Kb (kilobits).

Requests/sec = 120.

Buffer = 20% = 0.2.

Calculate Base Bandwidth:

Bits/sec = Payload * Requests = 8192 Kb * 120 = 983,040 Kb/s = 983.04 Mbps.

Add Buffer:

Total = Base * (1 + Buffer) = 983.04 * 1.2 = 1179.648 Mbps.

Evaluate Options: Closest to 1179.648 Mbps is 1152 Mbps (D)---realistic rounding.

Conclusion: D is correct.

OCI documentation advises: ''Calculate bandwidth as payload size (in bits) * requests/sec, then add a buffer (e.g., 20%) for peak loads.'' Here, 1024 KB = 8192 Kb, * 120 = 983.04 Mbps, * 1.2 = 1179.648 Mbps. D (1152 Mbps) is the closest practical option---452 (A) and 52 (B) are too low, 7052 (C) excessive.

7052 Mbps? What is this, the Autobahn for model deployments?

D) 1152 Mbps, no doubt. Gotta keep that model running at full speed!

C) 7052 Mbps? Really? That's overkill, even with the buffer percentage.

I'm going with B) 52 Mbps. That's a more reasonable bandwidth for a model deployment.

D) 1152 Mbps seems like the right answer, considering the payload size and estimated requests per second.

I’m a bit confused about the buffer percentage. Does it apply to the total bandwidth or just the payload? I wish I had practiced more with these types of questions.

If I remember right, the total bandwidth should be the payload size times requests, plus the buffer. I feel like the answer might be around 1152 Mbps.

I think we need to multiply the payload size by the requests per second and then add the buffer, but I can't recall the exact formula we used.

I remember we calculated bandwidth requirements in a similar practice question, but I'm not sure how to factor in the buffer percentage correctly.

This seems straightforward enough. I'll work through the calculations step-by-step and see which answer choice matches the result.

I think I've got it. We need to consider the total data transfer per second, factor in the buffer percentage, and then choose the appropriate answer option.
