Question 361

Report Export Collapse

A company uses AWS Key Management Service (AWS KMS). During an attempt to attach an encrypted Amazon Elastic Block Store (Amazon EBS) volume to an Amazon EC2 instance, the attachment fails.

A security engineer must recommend a solution to decrypt the EBS volume's encrypted data key. The solution must also attach the volume to the EC2 instance.

Which solution will meet these requirements?

Question 370

Report Export Collapse

A security engineer is investigating a malware infection that has spread across a set of Amazon EC2 instances. A key indicator of the compromise is outbound traffic on TCP port 2905 to a set of command and control hosts on the internet.

The security engineer creates a network ACL rule that denies the identified outbound traffic. The security engineer applies the network ACL rule to the subnet of the EC2 instances. The security engineer must identify any EC2 instances that are trying to communtcate on TCP port 2905.

Which solution will identify the affected EC2 instances with the LEAST operational effort?

An international company has established a new business entity in South Kore a. The company also has established a new AWS account to contain the workload for the South Korean region. The company has set up the workload in the new account in the ap-northeast-2 Region. The workload consists of three Auto Scaling groups of Amazon EC2 instances. All workloads that operate in this Region must keep system logs and application logs for 7 years. A security engineer must implement a solution to ensure that no logging data is lost for each instance during scaling activities. The solution also must keep the logs for only the required period of 7 years. Which combination of steps should the security engineer take to meet these requirements? (Choose three.)
A Security Architect has been asked to review an existing security architecture and identify why the application servers cannot successfully initiate a connection to the database servers. The following summary describes the architecture: 1 An Application Load Balancer, an internet gateway, and a NAT gateway are configured in the public subnet 2. Database, application, and web servers are configured on three different private subnets. 3 The VPC has two route tables: one for the public subnet and one for all other subnets The route table for the public subnet has a 0 0 0 0/0 route to the internet gateway The route table for all other subnets has a 0 0.0.0/0 route to the NAT gateway. All private subnets can route to each other 4 Each subnet has a network ACL implemented that limits all inbound and outbound connectivity to only the required ports and protocols 5 There are 3 Security Groups (SGs) database application and web Each group limits all inbound and outbound connectivity to the minimum required Which of the following accurately reflects the access control mechanisms the Architect should verify1?
A company Is planning to use Amazon Elastic File System (Amazon EFS) with its on-premises servers. The company has an existing IAM Direct Connect connection established between its on-premises data center and an IAM Region Security policy states that the company's on-premises firewall should only have specific IP addresses added to the allow list and not a CIDR range. The company also wants to restrict access so that only certain data center-based servers have access to Amazon EFS How should a security engineer implement this solution''
A company is using Amazon Route 53 Resolver for its hybrid DNS infrastructure. The company has set up Route 53 Resolver forwarding rules for authoritative domains that are hosted on on-premises DNS servers.

An IAM user receives an Access Denied message when the user attempts to access objects in an Amazon S3 bucket. The user and the S3 bucket are in the same AWS account. The S3 bucket is configured to use server-side encryption with AWS KMS keys (SSE-KMS) to encrypt all of its objects at rest by using a customer managed key from the same AWS account. The S3 bucket has no bucket policy defined. The IAM user has been granted permissions through an IAM policy that allows the kms:Decrypt permission to the customer managed key. The IAM policy also allows the s3:List* and s3:Get* permissions for the S3 bucket and its objects. Which of the following is a possible reason that the IAM user cannot access the objects in the S3 bucket?
A company is using AWS to run a long-running analysis process on data that is stored in Amazon S3 buckets. The process runs on a fleet of Amazon EC2 instances that are in an Auto Scaling group. The EC2 instances are deployed in a private subnet Of a VPC that does not have internet access. The EC2 instances and the S3 buckets are in the same AWS account The EC2 instances access the S3 buckets through an S3 gateway endpoint that has the default access policy. Each EC2 instance is associated With an instance profile role that has a policy that explicitly allows the s3:GetObject action and the s3:PutObject action for only the required S3 buckets. The company learns that one or more of the EC2 instances are compromised and are exfiltrating data to an S3 bucket that is outside the companys organization in AWS Organizations. A security engtneer must implement a solution to stop this exfiltration of data and to keep the EC2 processing job functional. Which solution will meet these requirements?
