The answer is Azure App Service, as it is the only service that fully meets the requirement for deploying a Linux container web app with built-in HTTPS, deployment slots, and autoscale while eliminating OS patching and container host management. Azure App Service natively supports Linux containers, automatically handles TLS/SSL termination for HTTPS, provides deployment slots for zero-downtime staging and production swaps, and offers autoscale rules based on metrics or schedules—all without requiring you to manage the underlying virtual machines or container orchestrators. On the AZ-104 exam, this question tests your ability to differentiate PaaS from IaaS solutions; a common trap is choosing Azure Container Instances or Azure Kubernetes Service, which lack built-in deployment slots and require you to manage patching or cluster nodes. Remember the mnemonic “SLOT-HA” for App Service: Slots, Linux, OS-free, TLS, HTTPS, Autoscale—if you need all six, App Service is the path.
AZ-104 Deploy and Manage Azure Compute Practice Question
This AZ-104 practice question tests your understanding of deploy and manage azure compute. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 developer packages an internal web app as a Linux container. The app must be published with built-in HTTPS, deployment slots, and autoscale, and the team does not want to manage OS patching or container hosts. Which Azure service should the administrator choose?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure App Service
Azure App Service is the correct choice because it natively supports Linux containers, built-in HTTPS via TLS/SSL, deployment slots for staging and production swaps, and autoscale based on metrics or schedules. It also abstracts OS patching and container host management, meeting the team's requirement to avoid managing infrastructure.
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.
✗
Azure Container Instances
Why it's wrong here
Container Instances is useful for simple containers, but it lacks the full web hosting features in this requirement.
✓
Azure App Service
Why this is correct
App Service supports web hosting features such as HTTPS, deployment slots, autoscale, and no server management.

✗
Azure Virtual Machines
Why it's wrong here
Virtual machines would require the team to manage the operating system, patching, and host configuration.
✗
Azure Kubernetes Service
Why it's wrong here
AKS is powerful for orchestration, but it adds cluster management that the requirement explicitly avoids.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Azure Kubernetes Service (D) for containerized apps, overlooking that App Service provides a simpler, fully managed solution with built-in deployment slots and autoscale, while AKS requires cluster management and lacks native slot support.
Detailed technical explanation
How to think about this question
Azure App Service for Linux containers uses a sandboxed environment where the container runs on a managed platform that automatically handles TLS termination at the front-end load balancer, enabling HTTPS without container-level configuration. Deployment slots allow zero-downtime deployments by routing a percentage of traffic to a staging slot, and autoscale uses Azure Monitor metrics to adjust instance counts based on CPU, memory, or custom rules. This service is ideal for web apps that need PaaS-level simplicity with containerization.

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.
