Which of the following describes AWS Local Zones?
A cluster of data centers in one geographic location
A site used by Amazon CloudFront to cache frequently accessed content
An extension of an AWS Region to more granular locations
One or more data centers with redundant power and networking
Explanations:
A cluster of data centers in one geographic location refers to an AWS Region, not Local Zones.
Amazon CloudFront is a content delivery network (CDN) and does not pertain to Local Zones.
Local Zones are extensions of AWS Regions that bring AWS services closer to users in specific geographic areas.
While Local Zones do have data centers, they are not defined simply as having redundant power and networking; this describes standard data center configurations.
I plot that the answer is:
An extension of an AWS Region to more granular locations
