Amazon AWS Certified Solutions Architect - Professional (SAP-C02) 認定 SAP-C02 試験問題 (Q804-Q809):

質問 # 804
A company wants to use Amazon Workspaces in combination with thin client devices to replace aging desktops Employees use the desktops to access applications that work with clinical trial data Corporate security policy states that access to the applications must be restricted to only company branch office locations. The company is considering adding an additional branch office in the next 6 months.
Which solution meets these requirements with the MOST operational efficiency?

A. Use AWS Certificate Manager (ACM) to issue trusted device certificates to the machines deployed in the branch office locations Enable restricted access on the Workspaces directory
B. Create a custom Workspace image with Windows Firewall configured to restrict access to the public addresses of the branch offices Use the image to deploy the Workspaces.
C. Use AWS Firewall Manager to create a web ACL rule with an IPSet with the list of public addresses from the branch office locations Associate the web ACL with the Workspaces directory
D. Create an IP access control group rule with the list of public addresses from the branch offices Associate the IP access control group with the Workspaces directory

正解：D

解説：
Explanation
Amazon WorkSpaces allows you to control which IP addresses your WorkSpaces can be accessed from. By using IP address-based control groups, you can define and manage groups of trusted IP addresses, and only allow users to access their WorkSpaces when they're connected to a trusted network. An IP access control group acts as a virtual firewall that controls the IP addresses from which users are allowed to access their WorkSpaces. To specify the CIDR address ranges, add rules to your IP access control group, and then associate the group with your directory. You can associate each IP access control group with one or more directories. You can create up to 100 IP access control groups per Region per AWS account. However, you can only associate up to 25 IP access control groups with a single directory.

質問 # 805
A company is planning to migrate its on-premises data analysis application to AWS. The application is hosted across a fleet of servers and requires consistent system time. The company has established an AWS Direct Connect connection from its on-premises data center to AWS.
The company has a high-precision stratum-0 atomic dock network appliance that acts as an NTP source for all on-premises servers.
After the migration to AWS is complete, the clock on all Amazon EC2 instances that host the application must be synchronized with the on-premises atomic clock network appliance.
Which solution will meet these requirements with the LEAST administrative overhead?

A. Deploy a third-party time server from the AWS Marketplace.
Configure the time server to synchronize with the on-premises atomic clock network appliance.
Ensure that NTP traffic is allowed inbound in the network ACLs for the VPC that contains the third-party server.
B. Configure a DHCP options set with the on-premises NTP server address.
Assign the options set to the VPC.
Ensure that NTP traffic is allowed between AWS and the on-premises networks.
C. Create an IPsec VPN tunnel from the on-premises atomic clock network appliance to the VPC to encrypt the traffic over the Direct Connect connection.
Configure the VPC route tables to direct NTP traffic over the tunnel.
D. Create a custom AMI to use the Amazon Time Sync Service at 169.254.169.123 Use this AMI for the application Use AWS Config to audit the NTP configuration.

正解：B

解説：
Setting a VPC DHCP options set with your on-prem NTP server IP makes every EC2 instance automatically use that clock source. Traffic rides the existing Direct Connect, so no extra tunnels or servers are needed - minimal admin overhead while meeting the requirement to sync to the on-prem atomic clock.

質問 # 806
A company has a legacy monolithic application that is critical to the company's business. The company hosts the application on an Amazon EC2 instance that runs Amazon Linux 2. The company's application team receives a directive from the legal department to back up the data from the instance's encrypted Amazon Elastic Block Store (Amazon EBS) volume to an Amazon S3 bucket. The application team does not have the administrative SSH key pair for the instance.
The application must continue to serve the users.
Which solution will meet these requirements?

A. Create an image of the instance with the reboot option turned on. Launch a new EC2 instance from the image. Attach a role to the new instance with permission to write to Amazon S3. Run a command to copy data into Amazon S3.
B. Take a snapshot of the EBS volume by using Amazon Data Lifecycle Manager (Amazon DLM).
Copy the data to Amazon S3.
C. Create an image of the instance. Launch a new EC2 instance from the image. Attach a role to the new instance with permission to write to Amazon S3. Run a command to copy data into Amazon S3.
D. Attach a role to the instance with permission to write to Amazon S3. Use the AWS Systems Manager Session Manager option to gain access to the instance and run commands to copy data into Amazon S3.

正解：D

解説：
AWS recommended to stop EC2 instances to create root volume snapshot.
When you create a snapshot for an EBS volume that serves as a root device, we recommend that you stop the instance before taking the snapshot.

質問 # 807
A company is running an application on several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer. The load on the application varies throughout the day, and EC2 instances are scaled in and out on a regular basis. Log files from the EC2 instances are copied to a central Amazon S3 bucket every 15 minutes. The security team discovers that log files are missing from some of the terminated EC2 instances.
Which set of actions will ensure that log files are copied to the central S3 bucket from the terminated EC2 instances?

A. Change the log delivery rate to every 5 minutes. Create a script to copy log files to Amazon S3, and add the script to EC2 instance user data. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to detect EC2 instance termination. Invoke an AWS Lambda function from the EventBridge (CloudWatch Events) rule that uses the AWS CLI to run the user-data script to copy the log files and terminate the instance.
B. Create an AWS Systems Manager document with a script to copy log files to Amazon S3. Create an Auto Scaling lifecycle hook and an Amazon EventBridge (Amazon CloudWatch Events) rule to detect lifecycle events from the Auto Scaling group. Invoke an AWS Lambda function on the autoscaling:EC2_INSTANCE_TERMINATING transition to call the AWS Systems Manager API SendCommand operation to run the document to copy the log files and send CONTINUE to the Auto Scaling group to terminate the instance.
C. Create an AWS Systems Manager document with a script to copy log files to Amazon S3. Create an Auto Scaling lifecycle hook that publishes a message to an Amazon Simple Notification Service (Amazon SNS) topic. From the SNS notification, call the AWS Systems Manager API SendCommand operation to run the document to copy the log files and send ABANDON to the Auto Scaling group to terminate the instance.
D. Create a script to copy log files to Amazon S3, and store the script in a file on the EC2 instance. Create an Auto Scaling lifecycle hook and an Amazon EventBridge (Amazon CloudWatch Events) rule to detect lifecycle events from the Auto Scaling group. Invoke an AWS Lambda function on the autoscaling:EC2_INSTANCE_TERMINATING transition to send ABANDON to the Auto Scaling group to prevent termination, run the script to copy the log files, and terminate the instance using the AWS SDK.

正解：B

解説：
https://docs.aws.amazon.com/autoscaling/ec2/userguide/adding-lifecycle-hooks.html
- Refer to Default Result section - If the instance is terminating, both abandon and continue allow the instance to terminate. However, abandon stops any remaining actions, such as other lifecycle hooks, and continue allows any other lifecycle hooks to complete.

質問 # 808
A team collects and routes behavioral data for an entire company The company runs a Multi-AZ VPC environment with public subnets, private subnets, and in internet gateway Each public subnet also contains a NAT gateway Most of the company's applications read from and write to Amazon Kinesis Data Streams. Most of the workloads am in private subnets.
A solutions architect must review the infrastructure The solutions architect needs to reduce costs and maintain the function of the applications The solutions architect uses Cost Explorer and notices that the cost in the EC2-Other category is consistently high A further review shows that NatGateway-Bytes charges are increasing the cost in the EC2-Other category.
What should the solutions architect do to meet these requirements?

A. Add an interface VPC endpoint for Kinesis Data Streams to the VPC. Ensure that the VPC endpoint policy allows traffic from the applications.
B. Enable VPC Flow Logs. Use Amazon Athena to analyze the logs for traffic that can be removed. Ensure that security groups are Mocking traffic that is responsible for high costs.
C. Enable VPC Flow Logs and Amazon Detective Review Detective findings for traffic that is not related to Kinesis Data Streams Configure security groups to block that traffic
D. Add an interface VPC endpoint for Kinesis Data Streams to the VPC. Ensure that applications have the correct IAM permissions to use the interface VPC endpoint.

正解：A

解説：
Explanation
https://docs.aws.amazon.com/vpc/latest/privatelink/vpc-endpoints-access.html
https://aws.amazon.com/premiumsupport/knowledge-center/vpc-reduce-nat-gateway-transfer-costs/ VPC endpoint policies enable you to control access by either attaching a policy to a VPC endpoint or by using additional fields in a policy that is attached to an IAM user, group, or role to restrict access to only occur via the specified VPC endpoint
