AWS Certified Solutions Architect – Professional — Question 274

True or False: In Amazon ElastiCache, you can use Cache Security Groups to configure the cache clusters that are part of a VPC.

Answer options

• A. FALSE
• B. TRUE
• C. True, this is applicable only to cache clusters that are running in an Amazon VPC environment.
• D. True, but only when you configure the cache clusters using the Cache Security Groups from the console navigation pane.

Correct answer: A

Explanation

Amazon ElastiCache Cache Security Groups are only used for clusters running in the EC2-Classic platform. For cache clusters deployed within an Amazon VPC, you must use standard Amazon VPC Security Groups instead. Therefore, Cache Security Groups cannot be used to configure clusters that are part of a VPC.
