1. A company hosts its product information webpages on AWS. The existing solution uses multiple Amazon C2 instances behind an Application Load Balancer in an Auto Scaling group. The website also uses a custom DNS name and communicates with HTTPS only using a dedicated SSL certificate. The company is planning a new product launch and wants to be sure that users from around the world have the best possible experience on the new website.What should a solutions architect do to meet these requirements?

A) Redesign the application to use AWS Elastic Beanstalk.
B) Redesign the application to use Amazon S3 static website hosting.
C) Redesign the application to use a Network Load Balancer.
D) Redesign the application to use Amazon CloudFront.



2. A company runs an application in a branch office within a small data closet with no virtualized compute resources. The application data is stored on an NFS volume. Compliance standards require a daily offsite backup of the NFS volume.Which solution meet these requirements?

A) Install an AWS Storage Gateway volume gateway with cached volumes on premises to replicate the data to Amazon S3.
B) Install an AWS Storage Gateway file gateway on premises to replicate the data to Amazon S3.
C) Install an AWS Storage Gateway volume gateway with stored volumes on premises to replicate the data to Amazon S3.
D) Install an AWS Storage Gateway file gateway hardware appliance on premises to replicate the data to Amazon S3.



3. A company is running an ecommerce application on Amazon EC2. The application consists of a stateless web tier that requires a minimum of 10 instances, and a peak of 250 instances to support the application's usage. The application requires 50 instances 80% of the time.Which solution should be used to minimize costs?

A) Purchase Reserved Instances to cover 50 instances. Use On-Demand and Spot Instances to cover the remaining instances.
B) Purchase Reserved Instances to cover 250 instances.
C) Purchase On-Demand Instances to cover 40 instances. Use Spot Instances to cover the remaining instances.
D) Purchase Reserved Instances to cover 80 instances. Use Spot Instances to cover the remaining instances.



4. A solution architect is designing a solution where users will be directed to a backup static error page if the primary website is unavailable. The primary website's DNS record are hosted in Amazon Route 53 where their domain is pointing to an Application Load Balancer (ALB).Which configuration should the solutions architect use to meet the company's needs while minimizing changes and infrastructure overhead?

A) Point a Route 53 alias record to an Amazon CloudFront distribution with the ALB as one of its origins. Then, create custom error pages for the distribution.
B) Set up a Route 53 active-passive failover configuration. Direct traffic to a static error page hosted within an Amazon S3 bucket when Route 53 health checks determine that the ALB endpoint is unhealthy.
C) Update the Route 53 record to use a latency-based routing policy. Add the backup static error page hosted within an Amazon S3 bucket to the record so the traffic is sent to the most responsive endpoint.s
D) Setup a Route 53 active-active configuration with the ALB and an Amazon EC2 instance hosting a static error page as endpoint. Route 53 will only send requests to the instance if the health checks fail for the ALB.



5. A company has deployed an API in a VPC behind an internet-facing Application Load Balancer (ALB). An application that consumers the API as a client is deployed in a second account in private subnets behind a NAT gateway. When requests to the client application increase, the NAT gateway costs are higher than expected. A solution architect has configured the ALB to be internal.Which combination of architectural changes will reduce the NAT gateway costs? (select two)(Select 2answers)

A) Configure an AWS Direct Connect connection between the two VPCs. Access the API using the private address.
B) Configure a Private Link connection for the API into the client VPC. Access the API using the Private Link address.
C) Configure an AWS Resource Access Manager connection between the two accounts. Access the API using the private address.
D) Configure a ClassicLink connection for the API into the client VPC. Access the API using the ClassicLink address.
E) Configure a VPC peering connection between the two VPCs. Access the API using the private address.
