Question:
Your company uses Azure Storage and wants to serve data from a custom domain. Which service should you use for this requirement?
Answer:
Azure CDN can work with a custom domain and caches content on edge servers that are close to end users. This reduces latency when users request content and is especially beneficial for globally distributed users.
While Azure Storage natively supports encryption in transit using Transport Layer Security (TLS), it does not natively support HTTPS with a custom domain. That's because the SSL certificate, used to serve over HTTPS, must be issued to the exact domain that's being accessed, and Azure Storage does not provide the ability to upload a custom SSL certificate.
Azure Storage Account Geo-redundancy provides data redundancy across regions, but does not provide the same content delivery speed benefits as Azure CDN.
Azure Traffic Manager is for network routing optimization and does not manage content caching for global distribution.
Azure Load Balancer is used to distribute network traffic, but doesn't provide content caching like a CDN.
