A. B. C. D.Answer - A,C and D.
To change the cache duration for all objects that match the same path pattern, you can change the CloudFront settings for Minimum TTL, Maximum TTL, and Default TTL for a cache behavior.
For more information on Cloudfront Cache, please refer to the below link:
http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Expiration.htmlCloudFront is Amazon Web Services' (AWS) content delivery network (CDN) service, which speeds up the distribution of content to users. CloudFront caches content in edge locations around the world, allowing for faster delivery to users. TTL, or Time to Live, is a setting that determines how long an object will remain in a cache before it expires and must be retrieved again from the origin server.
To change the cache behavior for objects stored in CloudFront, you can adjust the TTL settings using one or more of the following:
A. Minimum TTL: This is the shortest amount of time that an object will be cached in a CloudFront edge location. This setting can be used to ensure that frequently changing objects, such as news articles or stock prices, are always up to date.
B. Cache TTL: This is the amount of time that an object will be cached in a CloudFront edge location before it expires and must be retrieved again from the origin server. This setting can be used to balance the tradeoff between the speed of content delivery and the freshness of the content.
C. Maximum TTL: This is the longest amount of time that an object will be cached in a CloudFront edge location. This setting can be used to reduce the load on the origin server by allowing CloudFront to serve content from its cache for a longer period of time.
D. Default TTL: This is the default amount of time that an object will be cached in a CloudFront edge location if no other TTL settings are specified. It can be overridden by the other TTL settings.
In summary, A, B, and C are the correct answers, as they all relate to TTL settings that can be used to adjust the cache behavior for objects stored in CloudFront. The Default TTL is also a valid setting but is not explicitly related to changing cache behavior.
