A solutions architect is developing a multiple-subnet VPC architecture. The solution will consist of six subnets in two Availability Zones. The subnets are defined as public, private and dedicated for databases. Only the Amazon EC2 instances running in the private subnets should be able to access a database. Which solution meets these requirements?
A company creates operations data and stores the data in an Amazon S3 bucket for the company's annual audit, an external consultant needs to access an annual report that is stored in the S3 bucket. The external consultant needs to access the report for 7 days. The company must implement a solution to allow the external consultant access to only the report. Which solution will meet these requirements with the MOST operational efficiency?
A company stores data in an on-premises Oracle relational database. The company needs to make the data available in Amazon Aurora PostgreSQL for analysis The company uses an AWS Site-to-Site VPN connection to connect its on-premises network to AWS. The company must capture the changes that occur to the source database during the migration to Aurora PostgreSQL. Which solution will meet these requirements?
A development team uses multiple AWS accounts for its development, staging, and production environments. Team members have been launching large Amazon EC2 instances that are underutilized. A solutions architect must prevent large instances from being launched in all accounts. How can the solutions architect meet this requirement with the LEAST operational overhead?
A company stores customer data in a multitenant Amazon S3 bucket. Each customer's data is stored in a prefix that is unique to the customer. The company needs to migrate data for specific customers to a new. dedicated S3 bucket that is in the same AWS Region as the source bucket. The company must preserve object metadata such as creation date and version IDs. After the migration is finished, the company must delete the source data for the migrated customers from the original multitenant S3 bucket. Which combination of solutions will meet these requirements with the LEAST overhead? (Select THREE.)
A company hosts its multi-tier, public web application in the AWS Cloud. The web application runs on Amazon EC2 instances, and its database runs on Amazon RDS. The company is anticipating a large increase in sales during an upcoming holiday weekend. A solutions architect needs to build a solution to analyze the performance of the web application with a granularity of no more than 2 minutes. What should the solutions architect do to meet this requirement?
A company is implementing a new application on AWS. The company will run the application on multiple Amazon EC2 instances across multiple Availability Zones within multiple AWS Regions. The application will be available through the internet. Users will access the application from around the world. The company wants to ensure that each user who accesses the application is sent to the EC2 instances that are closest to the user's location. Which solution will meet these requirements?
A company hosts a web application on multiple Amazon EC2 instances The EC2 instances are in an Auto Scaling group that scales in response to user demand The company wants to optimize cost savings without making a long-term commitment Which EC2 instance purchasing option should a solutions architect recommend to meet these requirements'?
A company recently signed a contract with an AWS Managed Service Provider (MSP) Partner for help with an application migration initiative. A solutions architect needs to share an Amazon Machine Image (AMI) from an existing AWS account with the MSP Partner's AWS account.

Export

A company's developers want a secure way to gain SSH access on the company's Amazon EC2 instances that run the latest version of Amazon Linux. The developers work remotely and in the corporate office.

The company wants to use AWS services as a part of the solution. The EC2 instances are hosted in a VPC private subnet and access the internet through a NAT gateway that is deployed in a public subnet.

What should a solutions architect do to meet these requirements MOST cost-effectively?

A.
Create a bastion host in the same subnet as the EC2 instances. Grant the ec2: CreateVpnConnection 1AM permission to the developers. Install EC2 Instance Connect so that the developers can connect to the EC2 instances.

B.
Create an AWS Site-to-Site VPN connection between the corporate network and the VPC. Instruct the developers to use the Site-to-Site VPN connection to access the EC2 instances when the developers are on the corporate network. Instruct the developers to set up another VPN connection for access when they work remotely.

Instruct the developers to set up another VPN connection for access when they work remotely.
C.
Create a bastion host in the public subnet of the VPC. Configure the security groups and SSH keys of the bastion host to only allow connections and SSH authentication from the developers' corporate and remote networks. Instruct the developers to connect through the bastion host by using SSH to reach the EC2 instances.

Answers
D.
Attach the AmazonSSMManagedlnstanceCore 1AM policy to an 1AM role that is associated with the EC2 instances. Instruct the developers to use AWS Systems Manager Session Manager to access the EC2 instances.
Suggested answer: D

Explanation:

AWS Systems Manager Session Manager is a service that enables you to securely connect to your EC2 instances without using SSH keys or bastion hosts. You can use Session Manager to access your instances through the AWS Management Console, the AWS CLI, or the AWS SDKs. Session Manager uses IAM policies and roles to control who can access which instances. By attaching the AmazonSSMManagedlnstanceCore IAM policy to an IAM role that is associated with the EC2 instances, you grant the Session Manager service the necessary permissions to perform actions on your instances. You also need to attach another IAM policy to the developers' IAM users or roles that allows them to start sessions to the instances. Session Manager uses the AWS Systems Manager Agent (SSM Agent) that is installed by default on Amazon Linux 2 and other supported Linux distributions. Session Manager also encrypts all session data between your client and your instances, and streams session logs to Amazon S3, Amazon CloudWatch Logs, or both for auditing purposes. This solution is the most cost-effective, as it does not require any additional resources or services, such as bastion hosts, VPN connections, or NAT gateways. It also simplifies the security and management of SSH access, as it eliminates the need for SSH keys, port opening, or firewall rules.Reference:
