61. A company uses an Amazon Elastic Kubernetes Service (Amazon EKS) cluster to host its machine learning (ML) application. As the ML model and the container image size grow, the time that new pods take to start up has increased to several minutes.
A DevOps engineer needs to reduce the startup time to seconds. The solution must also reduce the startup time to seconds when the pod runs on nodes that were recently added to the cluster.
The DevOps engineer creates an Amazon EventBridge rule that invokes an automation in AWS Systems Manager. The automation prefetches the container images from an Amazon Elastic Container Registry (Amazon ECR) repository when new images are pushed to the repository. The DevOps engineer also configures tags to be applied to the cluster and the node groups.
What should the DevOps engineer do next to meet the requirements?
A. Create an IAM role that has a policy that allows EventBridge to use Systems Manager to run commands in the EKS cluster’s control plane nodes. Create a Systems Manager State Manager association that uses the control plane nodes’ tags to prefetch corresponding container images.
B. Create an IAM role that has a policy that allows EventBridge to use Systems Manager to run commands in the EKS cluster’s nodes. Create a Systems Manager State Manager association that uses the nodes’ machine size to prefetch corresponding container images.
C. Create an IAM role that has a policy that allows EventBridge to use Systems Manager to run commands in the EKS cluster’s nodes. Create a Systems Manager State Manager association that uses the nodes’ tags to prefetch corresponding container images.
D. Create an IAM role that has a policy that allows EventBridge to use Systems Manager to run commands in the EKS cluster’s control plane nodes. Create a Systems Manager State Manager association that uses the nodes’ tags to prefetch corresponding container images.

63. A DevOps engineer is building the infrastructure for an application. The application needs to run on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that includes Amazon EC2 instances. The EC2 instances need to use an Amazon Elastic File System (Amazon EFS) file system as a storage backend. The Amazon EFS Container Storage Interface (CSI) driver is installed on the EKS cluster.
When the DevOps engineer starts the application, the EC2 instances do not mount the EFS file system.
Which solutions will fix the problem? (Choose three.)
A. Switch the EKS nodes from Amazon EC2 to AWS Fargate.
B. Add an inbound rule to the EFS file system’s security group to allow NFS traffic from the EKS cluster.
C. Create an IAM role that allows the Amazon EFS CSI driver to interact with the file system
D. Set up AWS DataSync to configure file transfer between the EFS file system and the EKS nodes.
E. Create a mount target for the EFS file system in the subnet of the EKS nodes.
F. Disable encryption or the EFS file system.

64. A company deploys an application on on-premises devices in the company’s on-premises data center. The company uses an AWS Direct Connect connection between the data center and the company’s AWS account. During initial setup of the on-premises devices and during application updates, the application needs to retrieve configuration files from an Amazon Elastic File System (Amazon EFS) file system.
All traffic from the on-premises devices to Amazon EFS must remain private and encrypted. The on-premises devices must follow the principle of least privilege for AWS access. The company’s DevOps team needs the ability to revoke access from a single device without affecting the access of the other devices.
Which combination of steps will meet these requirements? (Choose two.)
A. Create an IAM user that has an access key and a secret key for each device. Attach the AmazonElasticFileSystemFullAccess policy to all IAM users. Configure the AWS CLI on the on-premises devices to use the IAM user’s access key and secret key.
B. Generate certificates for each on-premises device in AWS Private Certificate Authority. Create a trust anchor in IAM Roles Anywhere that references an AWS Private CA. Create an IAM role that trust IAM Roles Anywhere. Attach the AmazonElasticFileSystemClientReadWriteAccess to the role. Create an IAM Roles Anywhere profile for the IAM role. Configure the AWS CLI on the on-premises devices to use the aws_signing_helper command to obtain credentials.
C. Create an IAM user that has an access key and a secret key for all devices. Attach the AmazonElasticFileSystemClientReadWriteAccess policy to the IAM user. Configure the AWS CLI on the on-premises devices to use the IAM user’s access key and secret key.
D. Use the amazon-efs-utils package to mount the EFS file system.
E. Use the native Linux NFS client to mount the EFS file system.
