Sample Content Delivery Network Certification Practice Questions

Try these questions from our free Content Delivery Network Certification practice tests. The correct answer and an explanation follow each question.

1. Which CDN traffic management feature automatically routes traffic away from a failing origin region to a healthy backup region?

   • A. Rate limiting
   • B. Automatic failover / origin health checks
   • C. Request collapsing
   • D. Cache purging

Answer: B. Automatic failover / origin health checks

Origin health checks continuously probe origin endpoints and trigger automatic failover to backup origins when primary origins become unresponsive.

Answer: C. Server Name Indication (SNI)

SNI allows the client to send the requested hostname during the TLS handshake, enabling the server to select the correct certificate for that domain.

Answer: B. To assemble page fragments with different cache TTLs at the edge before delivery

ESI allows the CDN to cache page components independently and stitch them together at the edge, so personalized and cached sections coexist.

Answer: B. Follow established protocols for data protection, access control, and disclosure in accordance with applicable regulations

Confidential information must be handled according to established protocols, regulatory requirements, and professional ethics standards, including proper access control and disclosure procedures.
