B.
specific routing and bucket policies
C.
EC2 super policies and specific routing policies
D.
gateway load balancers and specific routing policies
A highly secure multitier application in AWS that includes S3, RDS, and some additional private links requires specific routing and bucket policies to keep the traffic safe. The reasons are as follows:
Specific routing policies are needed to ensure that the traffic between the tiers is routed through the private links, which provide secure and low-latency connectivity between AWS services and on-premises resources12. The private links can also prevent the exposure of the data and the application logic to the public internet12.
Bucket policies are needed to control the access to the S3 buckets that store the application data34. Bucket policies can specify the conditions under which the requests are allowed or denied, such as the source IP address, the encryption status, the request time, etc.34. Bucket policies can also enforce encryption in transit and at rest for the data in S334.
