Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A reporting server will run an in-memory analytics application that needs 8 vCPUs and 64 GiB of RAM. The administrator wants a VM family that is a good fit for memory-heavy workloads. Which VM family should be chosen?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Memory-optimized VM family
Memory-optimized sizes are designed for workloads that need a higher memory-to-vCPU ratio than general-purpose sizes. They are a practical fit for analytics engines, large caches, and in-memory databases where RAM is the main constraint. Choosing this family helps the team meet the workload requirement without paying for unnecessary specialized features that do not address the sizing need.
B
Distractor review
Burstable VM family
Burstable sizes are intended for light workloads with occasional CPU spikes, not sustained memory-heavy processing.
C
Distractor review
Compute-optimized VM family
Compute-optimized sizes prioritize CPU performance, which is less important than memory for this workload.
D
Distractor review
Storage-optimized VM family
Storage-optimized sizes focus on high disk throughput and IOPS rather than the memory capacity required here.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Memory-optimized VM family — Memory-optimized VM families are the best match when the workload needs a large amount of RAM relative to CPU. In this scenario, the application specifically requires 64 GiB of memory and benefits from a memory-rich configuration. Azure VM families in this category are commonly used for database engines, caching tiers, and analytics workloads. Selecting the right family helps satisfy the workload requirement efficiently and avoids overemphasizing CPU or disk performance. Why others are wrong: Burstable sizes are better for low-cost, intermittent workloads and can throttle under sustained demand. Compute-optimized sizes emphasize CPU power, which is not the main requirement here. Storage-optimized sizes are tuned for disk throughput and latency, but the scenario is driven by memory demand. None of those families provides the most appropriate memory-to-CPU balance for an in-memory analytics server.
