Quick Answer
The answer is to enable the 'HTTPS Only' setting within the Azure App Service configuration. This setting enforces HTTPS only on Azure App Service by automatically issuing a 301 redirect for any incoming HTTP request, forcing the client to reconnect over the encrypted HTTPS channel, which ensures all data in transit is protected by the bound SSL certificate. On the Microsoft Cybersecurity Architect exam, this tests your understanding of transport security enforcement at the platform level, often appearing as a straightforward configuration question designed to distinguish it from more complex options like client certificate authentication or TLS version restrictions. A common trap is confusing this with the 'FTPS only' setting or assuming a custom domain alone enforces encryption, but the 'HTTPS Only' toggle is the explicit, single-click solution. Memory tip: think "301 for 3-0-1" — the redirect code for HTTPS enforcement.
This SC-100 practice question tests your understanding of design a strategy for data and applications. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company deploys Azure App Service with a custom domain and SSL certificate. They want to enforce HTTPS only. Which configuration setting should they enable?
HTTPS Only
Enforces HTTPS redirect.
Client Certificates
Why wrong: For mutual authentication.
Minimum TLS Version
Why wrong: Controls allowed TLS version, not redirect.
Custom Domain
Why wrong: Just binds domain.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
HTTPS Only
The 'HTTPS Only' setting in Azure App Service enforces that all incoming requests are redirected from HTTP to HTTPS, ensuring encrypted communication. This is achieved by returning a 301 redirect for any HTTP request, which aligns with the requirement to enforce HTTPS only.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
HTTPS Only
Why this is correct
Enforces HTTPS redirect.
Related concept

Client Certificates
Why it's wrong here
For mutual authentication.
Minimum TLS Version
Why it's wrong here
Controls allowed TLS version, not redirect.
Custom Domain
Why it's wrong here
Just binds domain.
Common exam traps
The trap here is that candidates may confuse 'HTTPS Only' with 'Minimum TLS Version', thinking that setting a high TLS version also enforces HTTPS, but the latter only restricts the TLS protocol version without redirecting HTTP traffic.
Detailed technical explanation
Under the hood, the 'HTTPS Only' setting configures the Azure front-end load balancer to return an HTTP 301 redirect for any request arriving on port 80, effectively forcing clients to use port 443. This setting works at the platform level, before the request reaches the application code, so it cannot be overridden by application logic. In a real-world scenario, if this setting is disabled, clients could still access the site over unencrypted HTTP, exposing sensitive data to man-in-the-middle attacks.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
