How many Select Two (Multi-Select) Questions questions are on this page?

This page has 20 Select Two (Multi-Select) Questions scenario questions for the 1Z0-1127 exam, each with detailed explanations and wrong-answer analysis.

How should I approach 1Z0-1127 scenario questions?

Read the full scenario before looking at the answer options. Identify the constraint or requirement in the scenario, then eliminate options that are generally true but wrong for this specific case. Scenario questions reward careful reading over pattern matching.

How to approach select two (multi-select) questions

Multi-select questions tell you to 'Choose TWO' or 'Choose THREE'. Getting partial credit is not a thing — you must select all correct answers with no incorrect ones. The stem always states how many to choose, so trust it. These questions require precision, not best-guess elimination.

Quick answer

Select Two (Multi-Select) Questions questions test whether you can apply the concept in context, not just recognise a definition.

How the topic appears in realistic exam-style scenarios.

Which detail in the question changes the correct answer.

How to eliminate plausible but wrong options.

How to connect the question back to the wider exam objective.

Which TWO factors most significantly influence the computational cost of fine-tuning a large language model?

A
Batch size
Why wrong: Batch size affects memory but not per-token compute cost.
B
Number of model parameters
More parameters increase compute and memory requirements.
C
Maximum sequence length
Longer sequences increase attention computation and memory usage.
D
Quantization bits
Why wrong: Quantization reduces cost, not increases.
E
Dataset size
Why wrong: Dataset size affects total training time but not per-step cost.
