1. A company is hosting a website behind multiple Application Load Balancers. The company has different distribution rights for its content around the world. A solutions architect needs to ensure that users are served the correct content without violating distribution rights.Which configuration should the solutions architect choose to meet these requirements?

A) Configure Amazon Route 53 with a geoproximity routing policy.
B) Configure Application Load Balancers with AWS WAF.
C) Configure Amazon Route 53 with a geolocation policy.
D) Configure Amazon CloudFront with AWS WAF.



2. A company's application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. On the first day of every month at midnight, the application becomes much slower when the month-end financial calculation batch executes. This causes the CPU utilization of the EC2 instances to immediately peak to 100%, which disrupts the application.What should a solutions architect recommend to ensure the application is able to handle the workload and avoid downtime?

A) Configure an EC2 Auto Scaling simple scaling policy based on CPU utilization.
B) Configure Amazon ElastiGache to remove some of the workload from the EC2 instances.
C) Configure an Amazon CloudFront distribution in front of the ALB.
D) Configure an EC2 Auto Scaling scheduled scaling policy based on the monthly schedule.



3. A solutions architect is deploying a distributed database on multiple Amazon EC2 instances. The database stores all data on multiple instances so it can withstand the loss of an instance. The database requires block storage with latency and throughput to support several million transactions per second per server.Which storage solution should the solutions architect use?

A) Amazon EC2 instance store
B) Amazon EBS
C) Amazon EFS
D) Amazon S3



4. An application requires block storage for file updates. The data is 500 GB and must continuously sustain 100 MiB/s of aggregate read/write operations.Which storage option is appropriate for this application?

A) Amazon EBS
B) Amazon EFS
C) Amazon S3
D) Amazon Glacier



5. An Internet-facing multi-tier web application must be highly available. An ELB Classic Load Balancer is deployed in front of the web tier. Amazon EC2 instances at the web application tier are deployed evenly across two Availability Zones. The database is deployed using RDS Multi-AZ. A NAT instance is launched for Amazon EC2 instances and database resources to access the Internet. These instances are not assigned with public IP addresses.Which component poses a potential single point of failure in this architecture?

A) Amazon EC2
B) NAT instance
C) ELB Classic Load Balancer
D) Amazon RDS
