AZ-104 Deploy and Manage Azure Compute Practice Question
This AZ-104 practice question tests your understanding of deploy and manage azure compute. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A line-of-business app runs on a single Azure VM in a region that supports availability zones. The business wants the VM to keep running if one datacenter in the region becomes unavailable. Which deployment choice best meets this requirement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Availability zone
An availability zone is a physically separate datacenter within an Azure region, with independent power, cooling, and networking. Deploying the VM to a specific zone ensures it remains operational if another zone's datacenter fails, meeting the requirement for single-VM resilience against a datacenter outage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Availability set
Why it's wrong here
An availability set helps protect against host failures and planned maintenance, but it does not protect against a full datacenter outage.
✓
Availability zone
Why this is correct
An availability zone places the VM in a distinct datacenter within the region, helping the workload survive a datacenter-level outage.
Clue confirmation
The clue word "best" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Proximity placement group
Why it's wrong here
A proximity placement group improves low-latency placement, but it is not a high-availability feature for datacenter failure.
✗
Virtual machine scale set
Why it's wrong here
A scale set can help with scaling and instance redundancy, but the feature named here does not by itself guarantee zone-level placement.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse availability sets (which protect against rack-level failures) with availability zones (which protect against datacenter-level failures), leading them to choose the set when the question explicitly requires datacenter outage protection.
Detailed technical explanation
How to think about this question
Availability zones offer a 99.99% SLA for VMs when two or more instances are deployed across zones, but even a single VM in one zone is protected from other zone failures. Under the hood, each zone has a unique logical identifier (e.g., Zone 1, Zone 2, Zone 3) and is mapped to a physical datacenter; Azure ensures that zone-level failures are isolated. In a real-world scenario, if a regional disaster affects Zone 1, a VM in Zone 2 remains accessible, whereas an availability set would not survive the datacenter loss.
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.
TExam Day Tips
→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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
