質問 # 63
A company needs to view a list of security groups that are open to the internet on port 3389.
What should a CloudOps engineer do to meet this requirement?
正解：A
解説：
AWS Trusted Advisor includes security checks that identify security groups with unrestricted access to specific ports, including RDP on port 3389. This provides a direct way to review security groups that are exposed to the internet.
質問 # 64
A company runs an application on hundreds of Amazon EC2 instances in three Availability Zones. The application calls a third-party API over the public internet. A CloudOps engineer must provide the third party with a list of static IP addresses so that the third party can allow traffic from the application. Which solution will meet these requirements?
正解：B
解説：
A NAT gateway uses an Elastic IP address for outbound internet access from private subnets. By creating one NAT gateway in a public subnet in each Availability Zone and routing private subnet outbound traffic through the NAT gateway in the same Availability Zone, the company gets a small, stable list of public source IP addresses to give to the third party. This is also highly available because each Availability Zone has its own NAT gateway path.
質問 # 65
A company has a microservice that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). A CloudOps engineer must use Amazon Route 53 to create a record that maps the ALB URL to example.com.
Which type of Route 53 record will meet this requirement?
正解：D
解説：
Comprehensive Explanation (250-350 words):
Route 53 alias records are designed to map custom domain names to AWS resources such as ALBs, CloudFront distributions, and S3 website endpoints. Alias records behave like A records but point to AWS- managed resources instead of IP addresses.
Alias records are preferred over CNAME records because they can be used at the zone apex (example.com), do not incur additional DNS query charges, and automatically track changes to the underlying AWS resource.
A and AAAA records require fixed IP addresses, which ALBs do not provide. CNAME records cannot be used at the root domain.
Therefore, an alias record is the correct solution.
質問 # 66
A CloudOps engineer needs to build an event infrastructure for custom application-specific events. The events must be sent to an AWS Lambda function for processing. The CloudOps engineer must record the events so they can be replayed later by event type or event time. Which solution will meet these requirements?
正解：A
解説：
Amazon EventBridge supports custom event buses for application-specific events. EventBridge archives allow events to be retained and replayed later based on time ranges or event patterns, directly meeting the replay requirement.
Creating a custom event bus provides isolation and governance for application events. The archive preserves events automatically, and EventBridge rules route events to AWS Lambda for processing without custom code.
Options B and C do not properly align with custom event use cases or supported archive behavior.
Option D lacks native replay functionality.
Therefore, a custom event bus with an archive and rule is the correct solution.
質問 # 67
A company maintains a list of 75 approved Amazon Machine Images (AMIs) that can be used across an organization in AWS Organizations. The company's development team has been launching Amazon EC2 instances from unapproved AMIs.
A SysOps administrator must prevent users from launching EC2 instances from unapproved AMIs.
Which solution will meet this requirement?
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract of AWS CloudOps Documents:
The requirement is preventative: stop users from launching from unapproved AMIs. The most scalable approach with 75 approved AMIs is to tag all approved AMIs (for example, ApprovedAMI=true) and enforce usage through an IAM policy condition that only allows ec2:RunInstances when the ec2:ImageId resource (the AMI) includes the required tag. This avoids maintaining long allow/deny lists of AMI IDs and supports continuous updates: as new approved AMIs are created, tagging them automatically brings them under the policy without policy rewrites.
Option B is incorrect because service-linked roles are used by AWS services, not assigned to users for interactive authorization enforcement in this way. Option C and D are detective/remedial controls that act after instances are already launched, which does not satisfy "must prevent." They also increase operational overhead and risk disruptions.
