AWS Certified Solutions Architect CloudFront and Content Delivery 5

Question 1

A company is migrating to a new CloudFront distribution but wants to gradually shift traffic from the old distribution to the new one. Which CloudFront feature supports this use case?

Accepted Answer

CloudFront Continuous Deployment with traffic weights

Answer

CloudFront Continuous Deployment allows you to create a staging distribution and gradually shift a percentage of traffic to it before promoting it to production.

Question 2

An architect needs to configure CloudFront to automatically failover to a secondary S3 bucket if the primary S3 bucket returns 5xx errors. What should they configure?

Accepted Answer

CloudFront Origin Group with primary and secondary origins

Answer

CloudFront Origin Groups allow you to define a primary and secondary origin; CloudFront automatically fails over to the secondary when the primary returns specified HTTP status codes.

Question 3

A solutions architect wants to analyze CloudFront access patterns in near real-time to detect anomalies. Which CloudFront feature delivers log data within seconds of viewer requests?

Accepted Answer

CloudFront Real-Time Logs (Kinesis Data Streams)

Answer

CloudFront Real-Time Logs deliver log records to Amazon Kinesis Data Streams within seconds of viewer requests, enabling near real-time analysis.

Question 4

A company needs to serve their website through CloudFront using their own domain (www.example.com) with HTTPS. What are the TWO required components?

Accepted Answer

An ACM certificate in us-east-1 and a CNAME/Alias DNS record pointing to the CloudFront domain

Answer

CloudFront requires an ACM certificate provisioned in us-east-1 (N. Virginia) for custom SSL/TLS, plus a DNS CNAME or Route 53 Alias record pointing to the CloudFront distribution domain.

Question 5

A CloudFront distribution serves both static assets (images, CSS) and dynamic API calls. The architect wants to cache static assets for 1 year but never cache API responses. What is the correct configuration approach?

Accepted Answer

Create separate Cache Behaviors with different path patterns and TTL settings for each content type

Answer

Multiple Cache Behaviors with path patterns (e.g., /api/* vs /static/*) allow different caching policies and TTLs to be applied to different content types within a single distribution.
