As part of a migration strategy, a Solutions Architect needs to analyze workloads that can be optimized for performance and cost. The Solutions Architect has identified a stateless application that serves static content as a potential candidate to move to the cloud. The Solutions Architect has the flexibility to choose an identity solution between Facebook, Twitter, and Amazon.
Which AWS solution offers flexibility and ease of use, and the LEAST operational overhead for this migration?
A. Use AWS Identity and Access Management (IAM) for managing identities, and migrate the application to run on Amazon S3, Amazon API Gateway, and AWS Lambda.A Solutions Architect plans to migrate NAT instances to NAT gateway. The Architect has NAT instances with scripts to manage high availability. What is the MOST efficient method to achieve similar high availability with NAT gateway?
A. Remove source/destination check on NAT instances.An application tier currently hosts two web services on the same set of instances, listening on different ports.
Which AWS service should a Solutions Architect use to route traffic to the service based on the incoming request path?
A. AWS Application Load BalancerA company will run different data analytics jobs on large petabyte-scale datasets, using standard SQL and existing business intelligence tools.

A. An Amazon Aurora database cluster with 15 replicas distributed across Availability Zones.A Solutions Architect is designing a highly-available website that is served by multiple web servers hosted outside of AWS.

A. Use Amazon CloudWatch to monitor utilization.Amazon rds provides a facility to modify the back-up retention policy for automated backups, with a value of 0 indicating for no backup retention. What is the maximum retention period allowed in days?
A. 45What bandwidths do AWS Direct Connect currently support?
A. 10Mbps and 100MbpsA Solutions Architect is designing a three-tier web application that will allow customers to upload pictures from a mobile application. The application will then generate a thumbnail of the picture and return a message to the user confirming that the image was successfully uploaded. Generation of the thumbnail may take up to 5 seconds. To provide a sub second response time to the customers uploading the images, the Solutions Architect wants to separate the web tier from the application tier.
Which service would allow the presentation tier to asynchronously dispatch the request to the application tier?
A. AWS Step FunctionsA Solutions Architect is building a multi-tier website. The web servers will be in a public subnet, and the database servers will be in a private subnet. Only the web servers can be accessed from the Internet. The database servers must have
Internet access for software updates.
Which solution meets the requirements?
A. Assign Elastic IP addresses to the database instances.A Solutions Architect is creating a new relational database. The Compliance team will use the database, and mandates that data content must be stored across three different Availability Zones. Which of the following options should the Architect Use?
