Which AWS Service offers a complete cloud-powered Business Intelligence service that is charged on a pay-per-session pricing model?
AWS Quicksight
Which of the following AWS Security tools can protect your web applications or APIs against common web exploits that may affect availability, compromise security, or consume excessive resources?
AWS WAF
(*web application firewall)
You are required to host a website across a fleet of web servers on the Amazon platform. In order to build a highly cost-effective solution, you want to automatically provision additional web servers configured with the necessary application stack when demand on those servers increases over a period and then terminate web servers when there is a decrease in CPU load. How would you configure your solution?
Configure Auto Scaling to manage your web servers. As part of the configuration, configure and launch additional servers when CPU Utilization goes above a threshold for a short period of time. Configure the Auto Scaling service to terminate web servers when the CPU Utilization levels drop below a certain threshold for a specified period of time.
One of the seven design principals of the Security Pillar in the Well-Architected Framework refers to the concept
of applying security at all layers. Which two firewall options can you configure to protect your EC2 Instances deployed in a VPC? (Choose 2 answers)
- NACLs
- Security Groups
Which of the following describes a benefit of cloud computing that relates to its ability to scale out and scale in resources based on demand?

Which mode of Amazon ECS allows you to have control and manage your cluster of servers and schedule placement of containers on the servers?
EC2 Launch Type
Which AWS database solution enables you to build a complete data warehousing solution, capable of handling complex analytic queries against petabytes of structured data using standard SQL and industry recognized Business Intelligence (BI) tools?
AWS Redshift
Which AWS Service enables you to test a new IAM Policy to ensure that it will only allow access from a specific IP Address before deploying the policy?
IAM. Policy Simulator
You have been hired as a cloud consultant to design your clients’ web application architecture. A key requirement is to address a concern about building a second version of the web application so that if the primary site fails for any reason, customers can be redirected to the secondary site. You are also concerned about regional outages. How you would design this solution?
Build two versions of the site, primary site in your main region, and secondary site in another region. Configure Route53 with a Failover routing policy to switch to the secondary site if the primary site is down.
Each region consists of a minimum of two availability zones and many now have at least three availability zones. These availability zones are separated by a meaningful distance, many kilometers, from any other AZ, although all are within 100 km (60 miles) of each other. What is the primary benefit of having multiple AZs configured as above in each region?
To enable customers to deploy applications across these availability zones in a manner that would achieve high availability.
Your organization hosts multiple AWS Accounts with multiple VPCs. You would like to connect these VPCs together and centrally manage connectivity policies. Which AWS service enables you to connect multiple VPCs configured as a hub that controls how traffic is routed among all the connected networks which act like spokes?
AWS Transit Gateway.
Which type of EBS volume would you recommend for a high-performance application that is particularly sensitive to high latency?
EBS Provisioned IOPS SSD (io1)
You are building a multi-tier architecture with web servers placed in the public subnet and application servers placed in the private subnet of your VPC. You need to deploy Elastic Load Balancers to distribute traffic to both the web-server farm and the application server farm. Which type of load balancer would you choose to distribute traffic to your application servers?
Internal load balancers
