An AWS account that is used for development projects has a VPC that contains two subnets. The first subnet is named public-subnet-1 and has the CIDR block 192.168.1.0/24 assigned. The other subnet is named private-subnet-2 and has the CIDR block 192.168.2.0/24 assigned. Each subnet contains Amazon EC2 instances.
Each subnet is currently using the VPC's default network ACL. The security groups that the EC2 instances in these subnets use have rules that allow traffic between each instance where required. Currently, all network traffic flow is working as expected between the EC2 instances that are using these subnets.
A security engineer creates a new network ACL that is named subnet-2-NACL with default entries. The security engineer immediately configures private-subnet-2 to use the new network ACL and makes no other changes to the infrastructure. The security engineer starts to receive reports that the EC2 instances in public-subnet-1 and public-subnet-2 cannot communicate with each other.
Which combination of steps should the security engineer take to allow the EC2 instances that are running in these two subnets to communicate again? (Select TWO.)
A developer is building a serverless application hosted on AWS that uses Amazon Redshift as a data store The application has separate modules for readwrite and read-only functionality The modules need their own database users for compliance reasons
Which combination of steps should a security engineer implement to grant appropriate access? (Select TWO.)
A security engineer receives a notice from the AWS Abuse team about suspicious activity from a Linux-based Amazon EC2 instance that uses Amazon Elastic Block Store (Amazon EBS>-based storage The instance is making connections to known malicious addresses
The instance is in a development account within a VPC that is in the us-east-1 Region The VPC contains an internet gateway and has a subnet in us-east-1a and us-easMb Each subnet is associate with a route table that uses the internet gateway as a default route Each subnet also uses the default network ACL The suspicious EC2 instance runs within the us-east-1 b subnet. During an initial investigation a security engineer discovers that the suspicious instance is the only instance that runs in the subnet
Which response will immediately mitigate the attack and help investigate the root cause?
A company hosts an end user application on AWS Currently the company deploys the application on Amazon EC2 instances behind an Elastic Load Balancer The company wants to configure end-to-end encryption between the Elastic Load Balancer and the EC2 instances.
Which solution will meet this requirement with the LEAST operational effort?
A company has two VPCs in the same AWS Region and in the same AWS account Each VPC uses a CIDR block that does not overlap with the CIDR block of the other VPC One VPC contains AWS Lambda functions that run inside a subnet that accesses the internet through a NAT gateway. The Lambda functions require access to a publicly accessible Amazon Aurora MySQL database that is running in the other VPC
A security engineer determines that the Aurora database uses a security group rule that allows connections from the NAT gateway IP address that the Lambda functions use. The company's security policy states that no database should be publicly accessible.
What is the MOST secure way that the security engineer can provide the Lambda functions with access to the Aurora database?
