NEW QUESTION # 114
A company has several unencrypted EBS snapshots in their VPC. The Solutions Architect must ensure that all of the new EBS volumes restored from the unencrypted snapshots are automatically encrypted.
What should be done to accomplish this requirement?

• A. Launch new EBS volumes and specify the symmetric customer master key (CMK) for encryption.
• B. Launch new EBS volumes and encrypt them using an asymmetric customer master key (CMK).
• C. Enable the EBS Encryption By Default feature for specific EBS volumes.
• D. Enable the EBS Encryption By Default feature for the AWS Region.

Answer: D Explanation:
You can configure your AWS account to enforce the encryption of the new EBS volumes and snapshot copies that you create. For example, Amazon EBS encrypts the EBS volumes created when you launch an instance and the snapshots that you copy from an unencrypted snapshot.


Encryption by default has no effect on existing EBS volumes or snapshots. The following are important considerations in EBS encryption:
- Encryption by default is a Region-specific setting. If you enable it for a Region, you cannot disable it for individual volumes or snapshots in that Region.
- When you enable encryption by default, you can launch an instance only if the instance type supports EBS encryption.
- Amazon EBS does not support asymmetric CMKs.
When migrating servers using AWS Server Migration Service (SMS), do not turn on encryption by default. If encryption by default is already on and you are experiencing delta replication failures, turn off encryption by default. Instead, enable AMI encryption when you create the replication job.
You cannot change the CMK that is associated with an existing snapshot or encrypted volume. However, you can associate a different CMK during a snapshot copy operation so that the resulting copied snapshot is encrypted by the new CMK.
Although there is no direct way to encrypt an existing unencrypted volume or snapshot, you can encrypt them by creating either a volume or a snapshot. If you enabled encryption by default, Amazon EBS encrypts the resulting new volume or snapshot using your default key for EBS encryption. Even if you have not enabled encryption by default, you can enable encryption when you create an individual volume or snapshot. Whether you enable encryption by default or in individual creation operations, you can override the default key for EBS encryption and use symmetric customer-managed CMK. Hence, the correct answer is: Enable the EBS Encryption By Default feature for the AWS Region.
The option that says: Launch new EBS volumes and encrypt them using an asymmetric customer master key (CMK) is incorrect because Amazon EBS does not support asymmetric CMKs. To encrypt an EBS snapshot, you need to use symmetric CMK.
The option that says: Launch new EBS volumes and specify the symmetric customer master key (CMK) for encryption is incorrect. Although this solution will enable data encryption, this process is manual and can potentially cause some unencrypted EBS volumes to be launched. A better solution is to enable the EBS Encryption By Default feature. It is stated in the scenario that all of the new EBS volumes restored from the unencrypted snapshots must be automatically encrypted.
The option that says: Enable the EBS Encryption By Default feature for specific EBS volumes is incorrect because the Encryption By Default feature is a Region-specific setting and thus, you can't enable it to selected EBS volumes only.

NEW QUESTION # 115
A company needs to accelerate the performance of its AI-powered medical diagnostic application by running its machine learning workloads on the edge of telecommunication carriers' 5G networks. The application must be deployed to a Kubernetes cluster and have role-based access control (RBAC) access to IAM users and roles for cluster authentication.
Which of the following should the Solutions Architect implement to ensure single-digit millisecond latency for the application?

• A. Host the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. Set up node groups in AWS Wavelength Zones for the Amazon EKS cluster. Attach the Amazon EKS connector agent role (AmazonECSConnectorAgentRole) to your cluster and use AWS Control Tower for RBAC access.
• B. Host the application to an Amazon EKS cluster and run the Kubernetes pods on AWS Fargate. Create node groups in AWS Wavelength Zones for the Amazon EKS cluster. Add the EKS pod execution IAM role (AmazonEKSFargatePodExecutionRole) to your cluster and ensure that the Fargate profile has the same IAM role as your Amazon EC2 node groups.
• C. Launch the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. Create node groups in Wavelength Zones for the Amazon EKS cluster via the AWS Wavelength service. Apply the AWS authenticator configuration map (aws-auth ConfigMap) to your cluster.
• D. Launch the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. Create VPC endpoints for the AWS Wavelength Zones and apply them to the Amazon EKS cluster. Install the AWS IAM Authenticator for Kubernetes (aws-iam-authenticator) to your cluster.

Answer: C Explanation:
AWS Wavelength combines the high bandwidth and ultralow latency of 5G networks with AWS compute and storage services so that developers can innovate and build a new class of applications. Wavelength Zones are AWS infrastructure deployments that embed AWS compute and storage services within telecommunications providers' data centers at the edge of the 5G network, so application traffic can reach application servers running in Wavelength Zones without leaving the mobile providers' network.
This prevents the latency that would result from multiple hops to the internet and enables customers to take full advantage of 5G networks. Wavelength Zones extend AWS to the 5G edge, delivering a consistent developer experience across multiple 5G networks around the world. Wavelength Zones also allow developers to build the next generation of ultra-low latency applications using the same familiar AWS services, APIs, tools, and functionality they already use today.

Amazon EKS uses IAM to provide authentication to your Kubernetes cluster, but it still relies on native Kubernetes Role-Based Access Control (RBAC) for authorization. This means that IAM is only used for the authentication of valid IAM entities. All permissions for interacting with your Amazon EKS cluster's Kubernetes API are managed through the native Kubernetes RBAC system.
Access to your cluster using AWS Identity and Access Management (IAM) entities is enabled by the AWS IAM Authenticator for Kubernetes, which runs on the Amazon EKS control plane. The authenticator gets its configuration information from the aws-auth ConfigMap (AWS authenticator configuration map). The aws-auth ConfigMap is automatically created and applied to your cluster when you create a managed node group or when you create a node group using eksctl. It is initially created to allow nodes to join your cluster, but you also use this ConfigMap to add role-based access control (RBAC) access to IAM users and roles.
Hence, the correct answer is: Launch the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. Create node groups in Wavelength Zones for the Amazon EKS cluster via the AWS Wavelength service. Apply the AWS authenticator configuration map (aws-auth ConfigMap) to your cluster.
The option that says: Host the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. Set up node groups in AWS Wavelength Zones for the Amazon EKS cluster. Attach the Amazon EKS connector agent role (AmazonECSConnectorAgentRole) to your cluster and use AWS Control Tower for RBAC access is incorrect. An Amazon EKS connector agent is only used to connect your externally hosted Kubernetes clusters and to allow them to be viewed in your AWS Management Console. The AWS Control Tower doesn't provide RBAC access too to your EKS cluster. This service is commonly used for setting up a secure multi-account AWS environment and not for providing cluster authentication using IAM users and roles.
The option that says: Launch the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. Create VPC endpoints for the AWS Wavelength Zones and apply them to the Amazon EKS cluster. Install the AWS IAM Authenticator for Kubernetes (aws-iam-authenticator) to your cluster is incorrect because you cannot create VPC Endpoints in AWS Wavelength Zones. In addition, it is more appropriate to apply the AWS authenticator configuration map (aws-auth ConfigMap) to your Amazon EKS cluster to enable RBAC access.
The option that says: Host the application to an Amazon EKS cluster and run the Kubernetes pods on AWS Fargate. Create node groups in AWS Wavelength Zones for the Amazon EKS cluster. Add the EKS pod execution IAM role (AmazonEKSFargatePodExecutionRole) to your cluster and ensure that the Fargate profile has the same IAM role as your Amazon EC2 node groups is incorrect. Although this solution is possible, the security configuration of the Amazon EKS control plane is wrong. You have to ensure that the Fargate profile has a different IAM role as your Amazon EC2 node groups and not the other way around.

NEW QUESTION # 117
A Solutions Architect needs to set up a bastion host in the cheapest, most secure way. The Architect should be the only person that can access it via SSH.
Which of the following steps would satisfy this requirement?

• A. Set up a large EC2 instance and a security group that only allows access on port 22
• B. Set up a small EC2 instance and a security group that only allows access on port 22 via your IP address
• C. Set up a small EC2 instance and a security group that only allows access on port 22
• D. Set up a large EC2 instance and a security group that only allows access on port 22 via your IP address

Answer: B Explanation:
A bastion host is a server whose purpose is to provide access to a private network from an external network, such as the Internet. Because of its exposure to potential attack, a bastion host must minimize the chances of penetration.

To create a bastion host, you can create a new EC2 instance which should only have a security group from a particular IP address for maximum security. Since the cost is also considered in the question, you should choose a small instance for your host. By default, t2.micro instance is used by AWS but you can change these settings during deployment.
Setting up a large EC2 instance and a security group which only allows access on port 22 via your IP address is incorrect because you don't need to provision a large EC2 instance to run a single bastion host. At the same time, you are looking for the cheapest solution possible.
The options that say: Set up a large EC2 instance and a security group which only allows access on port 22 and Set up a small EC2 instance and a security group which only allows access on port 22 are both incorrect because you did not set your specific IP address to the security group rules, which possibly means that you publicly allow traffic from all sources in your security group. This is wrong as you should only be the one to have access to the bastion host.
