D) Add permission to use the KMS key to decrypt to the SSM service role.
E) Add permission to read the SSM parameter to the EC2 instance role


1. Right Answer: B
Explanation: The AWS(Amazon Web Service) Documentation mentions the following A VPC endpoint enables you to privately connect your VPC to supported AWS(Amazon Web Service) services and VPC endpoint services powered by PrivateLink without requiring an internet gateway, NAT device, VPN connection, or AWS(Amazon Web Service) Direct Connect connection. Instances in your VPC do not require public IP addresses to communicate with resources in the service. Traffic between your VPC and the other service does not leave the Amazon network. Option A is invalid because using a proxy server is not sufficient enough Option B and D are invalid because you need secure communication which should not traverse the internet For more information on VPC endpoints please see the below link https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-endpoints.html

2. Right Answer: A
Explanation: Option B is partially correct but a big maintenance over head to create and maintain a script when the functionality is already available in S3 Option C is invalid because snapshots are not available in S3 Option D is invalid because versioning will not replicate objects The AWS(Amazon Web Service) Documentation mentions the following Cross-region replication is a bucket-level configuration that enables automatic, asynchronous copying of objects across buckets in different AWS(Amazon Web Service) Regions. For more information on Cross region replication in the Simple Storage Service, please visit the below URL https://docs.aws.amazon.com/AmazonS3/latest/dev/crr.html

3. Right Answer: B,D
Explanation: This scenario is given in the AWS(Amazon Web Service) Documentation Option A and D are invalid because bucket ACL's are used to give grants to bucket owners. Option C is not required since encryption is not part of the requirement For more information on this scenario please see the below link https://docs.aws.amazon.com/AmazonS3/latest/dev/example-walkthroughs-managing-access-example3.html

4. Right Answer: B
Explanation: So definitely the case here is that the incident response plan is not catering to newly created services. AWS(Amazon Web Service) keeps on changing and adding new services and hence the response plan must cater to these new services. Option A and B are invalid because we don't know this for a fact. Option D is invalid because we know that the response plan is not complete , because it does not cater to new features of AWS For more information on incident response plan please visit the following url https://aws.amazon.com/blogs/publicsector/building-a-cloud-specific-incident-response-plan/
