Que 1: A DynamoDB database you manage is randomly experiencing heavy read requests that are causing latency. What is the simplest way to alleviate the performance issues?
Correct Answer: Create DynamoDB read replicas
Que 2: Encrypted Amazon Elastic Block Store (EBS) volumes are attached to some Amazon EC2 instances. Which statements are correct about using encryption with Amazon EBS volumes?
Correct Answer: Encryption is supported on all Amazon EBS volume types
Que 3: A company needs to capture detailed information about all HTTP requests that are processed by their Internet facing Application Load Balancer (ALB). The company requires information on the requester, IP address, and request type for analyzing traffic patterns to better understand their customer base.Which actions should a Solutions Architect recommend?
Correct Answer: Use CloudTrail to capture all API calls made to the ALB
Que 4: A Solutions Architect is developing a new web application on AWS that needs to be able to scale to support unpredictable workloads. The Architect prefers to focus on value-add activities such as software development and product roadmap development rather than provisioning and managing instances.Which solution is most appropriate for this use case?
Correct Answer: Elastic Load Balancing with Auto Scaling groups and Amazon EC2
Que 5: A company requires an Elastic Load Balancer (ELB) for an application they are planning to deploy on AWS. The application requires extremely high throughput and extremely low latencies. The connections will be made using the TCP protocol and the ELB must support load balancing to multiple ports on an instance. Which ELB would should the company use?
Correct Answer: Application Load Balancer
Que 6: A government agency is using CloudFront for a web application that receives personally identifiable information (PII) from citizens.What feature of CloudFront applies an extra level of encryption at CloudFront edge locations to ensure the PII data is secured end-to-end?
Correct Answer: RTMP distribution
Que 7: An application makes calls to a REST API running on Amazon EC2 instances behind an Application Load Balancer (ALB). Most API calls complete quickly. However, a single endpoint is making API calls that require much longer to complete and this is introducing overall latency into the system. What steps can a Solutions Architect take to minimize the effects of the long-running API calls?
Correct Answer: Increase the ALB idle timeout to allow the long-running requests to complete
Que 8: A company needs to ensure that they can failover between AWS Regions in the event of a disaster seamlessly with minimal downtime and data loss. The applications will run in an active-active configuration.Which DR strategy should a Solutions Architect recommend?
Correct Answer: Pilot light
Que 9: A Solutions Architect is designing the disk configuration for an Amazon EC2 instance. The instance needs to support a MapReduce process that requires high throughput for a large dataset with large I/O sizes.Which Amazon EBS volume is the MOST cost-effective solution for these requirements?
Correct Answer: EBS General Purpose SSD
Que 10: An application uses an Amazon RDS database and Amazon EC2 instances in a web tier. The web tier instances must not be directly accessible from the internet to improve security.How can a Solutions Architect meet these requirements?
Correct Answer: Launch the EC2 instances in a public subnet and create an Application Load Balancer in a public subnet
Que 11: A Solutions Architect needs to capture information about the traffic that reaches an Amazon Elastic Load Balancer. The information should include the source, destination, and protocol.What is the most secure and reliable method for gathering this data?
Correct Answer: Create a VPC flow log for the subnets in which the ELB is running
Que 12: The development team in a media organization is moving their SDLC processes into the AWS Cloud. Which AWS service can a Solutions Architect recommend that is primarily used for software version control?
Correct Answer: CodeCommit
Que 13: A Solutions Architect manages multiple Amazon RDS MySQL databases. To improve security, the Solutions Architect wants to enable secure user access with short-lived credentials. How can these requirements be met?
Correct Answer: Configure the application to use the AUTH command to send a unique password.
Que 14: A company is transitioning their web presence into the AWS cloud. As part of the migration the company will be running a web application both on-premises and in AWS for a period of time. During the period of co-existence the client would like 80% of the traffic to hit the AWS-based web servers and 20% to be directed to the on-premises web servers.What method can a Solutions Architect use to distribute traffic as requested?
Correct Answer: Use a Network Load Balancer to distribute traffic based on Instance ID.
Que 15: A Solutions Architect is designing the system monitoring and deployment layers of a serverless application. The system monitoring layer will manage system visibility through recording logs and metrics and the deployment layer will deploy the application stack and manage workload changes through a release management process.
The Architect needs to select the most appropriate AWS services for these functions. Which services and frameworks should be used for the system monitoring and deployment layers?
Correct Answer: Use AWS CloudTrail for consolidating system and application logs and monitoring custom metrics
