A stateless web tier must survive a datacenter outage in a region that supports availability zones, and the number of instances should increase during business hours. Which three actions should the administrator take? Select three.
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
Deploy the workload as a virtual machine scale set instead of a standalone VM.
A VM scale set is the Azure compute service designed for identical, horizontally scalable instances. It gives the administrator a single resource to manage for deployment, scaling, and placement across multiple instances.
B
Best answer
Enable zone distribution for the scale set in a region that supports availability zones.
Zone distribution allows the scale set to place instances across zones, improving resilience against a datacenter failure. This is the correct way to add zone-level protection while keeping the workload managed as one scalable unit.
C
Best answer
Configure autoscale so the instance count can change according to demand.
Autoscale is the feature that adds and removes instances based on defined rules or schedules. It matches the requirement for increasing capacity during business hours without manual intervention.
D
Distractor review
Place all instances in a single availability set and scale them manually.
An availability set helps with host-level resilience, but it does not provide zone-level fault isolation. Manual scaling also misses the requirement for automatic instance growth during busy periods.
E
Distractor review
Deploy only one zonal VM and use snapshots to recover if the datacenter fails.
One VM is still a single point of failure, and snapshots do not provide active service continuity. The requirement calls for multiple instances and automated scaling, which a VM scale set supports.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Deploy the workload as a virtual machine scale set instead of a standalone VM. — A zone-aware VM scale set is the best fit when you need both resilience and elastic capacity. The scale set manages identical instances, zone distribution helps absorb a datacenter outage, and autoscale adjusts instance count as demand changes. This combination directly addresses availability and scaling without forcing the team to manage each VM separately. Why others are wrong: An availability set does not protect against a zone failure, and manual scaling defeats the automation requirement. A single VM with snapshots is a recovery plan, not an availability plan. The scenario needs multiple managed instances, zone placement, and automatic scale behavior.
