True or False: In Amazon ElastiCache, you can use Cache Security Groups to configure the cache clusters that are part of a VPC.

A large global company wants to migrate a stateless mission-critical application to AWS. The application is based on IBM WebSphere (application and integration middleware), IBM MQ (messaging middleware), and IBM DB2 (database software) on a z/OS operating system. How should the Solutions Architect migrate the application to AWS?

A large company recently experienced an unexpected increase in Amazon RDS and Amazon DynamoDB costs. The company needs to increase visibility into delays of AWS Billing and Cost Management. There are various accounts associated with AWS Organizations, including many development and production accounts. There is no consistent tagging strategy across the organization, but there are guidelines in place that require all infrastructure to be deployed using AWS CloudFormation with consistent tagging. Management requires cost center numbers and project ID numbers for all existing and future DynamoDB tables and RDS distances. Which strategy should the solutions architect provide to meet these requirements?

A company is migrating applications from on premises to the AWS Cloud. These applications power the company's internal web forms. These web forms collect data for specific events several times each quarter. The web forms use simple SQL statements to save the data to a local relational database. Data collection occurs for each event, and the on-premises servers are idle most of the time. The company needs to minimize the amount of idle infrastructure that supports the web forms. Which solution will meet these requirements?

ABC has created a multi-tenant Learning Management System (LMS). The application is hosted for five different tenants (clients) in the VPCs of the respective AWS accounts of the tenant. ABC wants to setup a centralized server which can connect with the LMS of each tenant upgrade if required. ABC also wants to ensure that one tenant VPC should not be able to connect to the other tenant VPC for security reasons. How can ABC setup this scenario?

A financial company with multiple departments wants to expand its on-premises environment to the AWS Cloud. The company must retain centralized access control using an existing on-premises Active Directory (AD) service. Each department should be allowed to create AWS accounts with preconfigured networking and should have access to only a specific list of approved services. Departments are not permitted to have account administrator permissions. What should a solutions architect do to meet these security requirements?

To scale out the AWS resources using manual AutoScaling, which of the below mentioned parameters should the user change?

An elastic network interface (ENI) is a virtual network interface that you can attach to an instance in a VPC. An ENI can include one public IP address, which can be auto-assigned to the elastic network interface for eth0 when you launch an instance, but only when you_____.

You are designing an SSL/TLS solution that requires HTTPS clients to be authenticated by the Web server using client certificate authentication. The solution must be resilient. Which of the following options would you consider for configuring the web server infrastructure? (Choose two.)

You have custom Network File System (NFS) client settings for your Amazon Elastic File System (EFS). It takes up to three seconds for an Amazon Elastic Compute Cloud (EC2) instance to see a write operation performed on a file system from another Amazon EC2 instance. Which of the following actions should you take to solve the custom NFS settings from causing delays in the write operation?

You are the new IT architect in a company that operates a mobile sleep tracking application. When activated at night, the mobile app is sending collected data points of 1 kilobyte every 5 minutes to your backend. The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB table. Every morning, you scan the table to extract and aggregate last night's data on a per user basis, and store the results in Amazon S3. Users are notified via Amazon SNS mobile push notifications that new data is available, which is parsed and visualized by the mobile app. Currently you have around 100k users who are mostly based out of North America. You have been tasked to optimize the architecture of the backend system to lower cost. What would you recommend? (Choose two.)

A company has been using a third-party provider for its content delivery network and recently decided to switch to Amazon CloudFront. The development team wants to maximize performance for the global user base. The company uses a content management system (CMS) that serves both static and dynamic content. The CMS is behind an Application Load Balancer (ALB) which is set as the default origin for the distribution. Static assets are served from an Amazon S3 bucket. The Origin Access Identity (OAI) was created properly and the S3 bucket policy has been updated to allow the GetObject action from the OAI, but static assets are receiving a 404 error. Which combination of steps should the solutions architect take to fix the error? (Choose two.)

A company has a Microsoft SQL Server database in its data center and plans to migrate data to Amazon Aurora MySQL. The company has already used the AWS Schema Conversion Tool to migrate triggers, stored procedures and other schema objects to Aurora MySQL. The database contains 1 TB of data and grows less than 1 MB per day. The company's data center is connected to AWS through a dedicated 1Gbps AWS Direct Connect connection. The company would like to migrate data to Aurora MySQL and perform reconfigurations with minimal downtime to the applications. Which solution meets the company's requirements?

A company is storing data on Amazon Simple Storage Service (S3). The company's security policy mandates that data is encrypted at rest. Which of the following methods can achieve this? (Choose three.)

In a VPC, can you modify a set of DHCP options after you create them?

A company is adding a new approved external vendor that only supports IPv6 connectivity. The company's backend systems sit in the private subnet of an Amazon VPC. The company uses a NAT gateway to allow these systems to communicate with external vendors over IPv4. Company policy requires systems that communicate with external vendors to use a security group that limits access to only approved external vendors. The virtual private cloud (VPC) uses the default network ACL. The Systems Operator successfully assigns IPv6 addresses to each of the backend systems. The Systems Operator also updates the outbound security group to include the IPv6 CIDR of the external vendor (destination). The systems within the VPC are able to ping one another successfully over IPv6. However, these systems are unable to communicate with the external vendor. What changes are required to enable communication with the external vendor?

During a security audit of a Service team's application, a Solutions Architect discovers that a username and password for an Amazon RDS database and a set of AWS IAM user credentials can be viewed in the AWS Lambda function code. The Lambda function uses the username and password to run queries on the database, and it uses the IAM credentials to call AWS services in a separate management account. The Solutions Architect is concerned that the credentials could grant inappropriate access to anyone who can view the Lambda code. The management account and the Service team's account are in separate AWS Organizations organizational units (OUs). Which combination of changes should the Solutions Architect make to improve the solution's security? (Choose two.)

A Solutions Architect is designing a network solution for a company that has applications running in a data center in Northern Virginia. The applications in the company's data center require predictable performance to applications running in a virtual private cloud (VPC) located in us-east-1, and a secondary VPC in us-west-2 within the same account. The company data center is collocated in an AWS Direct Connect facility that serves the us-est-1 region. The company has already ordered an AWS Direct Connect connection and a cross-connect has been established. Which solution will meet the requirements at the LOWEST cost?
