Quick Answer
The answer is Azure Traffic Manager and Azure Front Door. These two services are correct because they both provide global, DNS-based traffic routing and intelligent failover across multiple Azure regions, which is essential for cross-region disaster recovery for Azure App Service web applications with a custom domain. Traffic Manager operates at the DNS level to direct users to the nearest healthy endpoint, while Front Door adds application-layer acceleration and health monitoring, making both suitable for redirecting traffic to a secondary region during a primary region outage. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this question tests your understanding of global versus regional load balancing—a common trap is confusing Azure Application Gateway, which is regional and cannot route across regions, with these global services. Remember the mnemonic “Global Failover, Not Regional” to distinguish Traffic Manager and Front Door from regional options like Application Gateway.
This AZ-305 practice question tests your understanding of design business continuity solutions. 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.
Which TWO Azure services can be used to provide cross-region disaster recovery for Azure App Service web applications with a custom domain? (Select TWO.)
Azure DNS
Why wrong: Azure DNS provides name resolution, not traffic routing.
Azure Front Door
Front Door provides global load balancing and automatic failover.
Azure CDN
Why wrong: CDN is for content delivery, not disaster recovery.
Azure Application Gateway
Why wrong: Application Gateway is a regional load balancer.
Azure Traffic Manager
Traffic Manager can route traffic to a secondary endpoint.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Front Door
Options A and B are correct. Azure Traffic Manager can route traffic to a secondary region App Service in case of primary region failure. Azure Front Door provides global load balancing and failover. Options C, D, and E are wrong: Azure Application Gateway is regional, Azure DNS does not provide traffic routing, and Azure CDN is for content caching, not failover.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
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.
Detailed technical explanation
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.
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.
