Which AWS instance address has the following characteristics? :"If you stop an instance, its Elastic IP address is unmapped, and you must remap it when you restart the instance."

Someone is creating a VPC for their application hosting. He has created two private subnets in the same availability zone and created one subnet in a separate availability zone. He wants to make a High Availability system with an internal Elastic Load Balancer. Which choice is true regarding internal ELBs in this scenario? (Choose two.)

A company has implemented AWS Organizations. It has recently set up a number of new accounts and wants to deny access to a specific set of AWS services in these new accounts. How can this be controlled MOST efficiently?

A company is using an Amazon CloudFront distribution to distribute both static and dynamic content from a web application running behind an Application Load Balancer. The web application requires user authorization and session tracking for dynamic content. The CloudFront distribution has a single cache behavior configured to forward the Authorization , Host , and User-Agent HTTP whitelist headers and a session cookie to the origin. All other cache behavior settings are set to their default value. A valid ACM certificate is applied to the CloudFront distribution with a matching CNAME in the distribution settings. The ACM certificate is also applied to the HTTPS listener for the Application Load Balancer. The CloudFront origin protocol policy is set to HTTPS only. Analysis of the cache statistics report shows that the miss rate for this distribution is very high. What can the Solutions Architect do to improve the cache hit rate for this distribution without causing the SSL/TLS handshake between CloudFront and the Application Load Balancer to fail?

You're running an application on-premises due to its dependency on non-x86 hardware and want to use AWS for data backup. Your backup application is only able to write to POSIX-compatible block-based storage. You have 140TB of data and would like to mount it as a single folder on your file server. Users must be able to access portions of this data while the backups are taking place. What backup solution would be most appropriate for this use case?

What types of identities do Amazon Cognito identity pools support?

You are implementing a URL whitelisting system for a company that wants to restrict outbound HTTP'S connections to specific domains from their EC2-hosted applications. You deploy a single EC2 instance running proxy software and configure It to accept traffic from all subnets and EC2 instances in the VPC. You configure the proxy to only pass through traffic to domains that you define in its whitelist configuration. You have a nightly maintenance window or 10 minutes where all instances fetch new software updates. Each update Is about 200MB In size and there are 500 instances In the VPC that routinely fetch updates. After a few days you notice that some machines are failing to successfully download some, but not all of their updates within the maintenance window. The download URLs used for these updates are correctly listed in the proxy's whitelist configuration and you are able to access them manually using a web browser on the instances. What might be happening? (Choose two.)

The following are AWS Storage services? (Choose two.)

An organization is setting up a highly scalable application using Elastic Beanstalk. They are using Elastic Load Balancing (ELB) as well as a Virtual Private Cloud (VPC) with public and private subnets. They have the following requirements: - All the EC2 instances should have a private IP - All the EC2 instances should receive data via the ELB's. Which of these will not be needed in this setup?

A company is running multiple applications on Amazon EC2. Each application is deployed and managed by multiple business units. All applications are deployed on a single AWS account but on different virtual private clouds (VPCs). The company uses a separate VPC in the same account for test and development purposes. Production applications suffered multiple outages when users accidentally terminated and modified resources that belonged to another business unit. A Solutions Architect has been asked to improve the availability of the company applications while allowing the Developers access to the resources they need. Which option meets the requirements with the LEAST disruption?

The ACM certificate is also applied to the HTTPS listener for the Application Load Balancer. The CloudFront origin protocol policy is set to HTTPS only. Analysis of the cache statistics report shows that the miss rate for this distribution is very high. What can the Solutions Architect do to improve the cache hit rate for this distribution without causing the SSL/TLS handshake between CloudFront and the Application Load Balancer to fail?

Can you configure multiple Load Balancers with a single Auto Scaling group?

A company runs a dynamic mission-critical web application that has an SLA of 99.99%. Global application users access the application 24/7. The application is currently hosted on premises and routinely fails to meet its SLA, especially when millions of users access the application concurrently. Remote users complain of latency. How should this application be redesigned to be scalable and allow for automatic failover at the lowest cost?

A user has configured EBS volume with PIOPS. The user is not experiencing the optimal throughput. Which of the following could not be factor affecting I/O performance of that EBS volume?

A company has a photo sharing social networking application. To provide a consistent experience for users, the company performs some image processing on the photos uploaded by users before publishing on the application. The image processing is implemented using a set of Python libraries. The current architecture is as follows: The image processing Python code runs in a single Amazon EC2 instance and stores the processed images in an Amazon S3 bucket named ImageBucket. The front-end application, hosted in another bucket, loads the images from ImageBucket to display to users. With plans for global expansion, the company wants to implement changes in its existing architecture to be able to scale for increased demand on the application and reduce management complexity as the application scales. Which combination of changes should a solutions architect make? (Choose two.)

A company has an internal application running on AWS that is used to track and process shipments in the company's warehouse. Currently, after the system receives an order, it emails the staff the information needed to ship a package. Once the package is shipped, the staff replies to the email and the order is marked as shipped. The company wants to stop using email in the application and move to a serverless application model. Which architecture solution meets these requirements?

An organization has setup RDS with VPC. The organization wants RDS to be accessible from the internet. Which of the below mentioned configurations is not required in this scenario?

An enterprise company's data science team wants to provide a safe, cost-effective way to provide easy access to Amazon SageMaker. The data scientists have limited AWS knowledge and need to be able to launch a Jupyter notebook instance. The notebook instance needs to have a preconfigured AWS KMS key to encrypt data at rest on the machine learning storage volume without exposing the complex setup requirements. Which approach will allow the company to set up a self-service mechanism for the data scientists to launch Jupyter notebooks in its AWS accounts with the LEAST amount of operational overhead?

A media company is serving video files stored in Amazon S3 using Amazon CloudFront. The development team needs access to the logs to diagnose faults and perform service monitoring. The log files from CloudFront may contain sensitive information about users. The company uses a log processing service to remove sensitive information before making the logs available to the development team. The company has the following requirements for the unprocessed logs: The logs must be encrypted at rest and must be accessible by the log processing service only. Only the data protection team can control access to the unprocessed log files. AWS CloudFormation templates must be stored in AWS CodeCommit. AWS CodePipeline must be triggered on commit to perform updates made to CloudFormation templates. CloudFront is already writing the unprocessed logs to an Amazon S3 bucket, and the log processing service is operating against this S3 bucket. Which combination of steps should a solutions architect take to meet the company's requirements? (Choose two.)
