Question #18
A developer wants to use an Amazon CloudFront distribution to deliver a web application to users. Users will access the application through the internet. The developer needs to create an SSL/TLS certificate to use with the CloudFront distribution. The developer wants to minimize operational overhead by ensuring that the certificate is renewed automatically. Which solution will meet these requirements? The best answer is to request a public certificate in AWS Certificate Manager and validate it with DNS. ACM manages public certificate renewal automatically when validation remains in place, which minimizes operational overhead. DNS validation is preferable to email validation because it does not require manual approval emails during renewal workflows. IAM server certificates are legacy-style certificate storage and do not provide the same managed lifecycle experience as ACM. Imported certificates are not automatically renewed by ACM because ACM does not control their issuance lifecycle. For CloudFront, AWS recommends ACM certificates, and CloudFront certificates must be requested or imported in the US East (N. Virginia) Region, although the option's key point is ACM public certificate with DNS validation. (AWS Documentation) ===============
A. Create a public certificate that uses DNS validation in IAM
B. Import a certificate into IAM
C. Create a public certificate that uses DNS validation in AWS Certificate Manager (ACM)
D. Create a public certificate that uses email validation in AWS Certificate Manager (ACM)

Question #47
A developer is testing a new file storage application that uses an Amazon CloudFront distribution to serve content from an Amazon S3 bucket. The distribution accesses the S3 bucket by using an origin access identity (OAI). The S3 bucket's permissions explicitly deny access to all other users.The application prompts users to authenticate on a login page and then uses signed cookies to allow users to access their personal storage directories. The developer has configured the distribution to use its default cache behavior with restricted viewer access and has set the origin to point to the S3 bucket. However, when the developer tries to navigate to the login page, the developer receives a 403 Forbidden error.The developer needs to implement a solution to allow unauthenticated access to the login page. The solution also must keep all private content secure.Which solution will meet these requirements?
