질문 # 140
A company hosts its website on Amazon EC2 instances in the us-east-1 Region. The company is preparing to extend its website into the eu-central-1 Region, but the database must remain only in us-east-1. After deployment, the EC2 instances in eu-central-1 are unable to connect to the database in us-east-1. What is the MOST operationally efficient solution that will resolve this connectivity issue?
정답：B
설명：
Inter-Region VPC peering provides private connectivity between VPCs in different AWS Regions without requiring VPN infrastructure. After configuring the required routes, the database security group can allow inbound database traffic from the private CIDR range used by the EC2 instances in eu-central-1, providing a straightforward and low-overhead solution.
질문 # 141
A company needs to ensure that an AWS Lambda function can access resources in a VPC in the company's account. The Lambda function requires access to third-party APIs that can be accessed only over the internet.
Which action should a SysOps administrator take to meet these requirements?
정답：B
설명：
Lambda functions configured to run in a VPC require network egress to reach the internet for external APIs. A private subnet with a default route to a NAT gateway provides outbound internet access for the Lambda without exposing the Lambda's resources to inbound internet traffic. This setup preserves the security of the VPC while enabling internet access for external API calls. The NAT gateway handles outbound connections on behalf of resources in the private subnet, ensuring stable and scalable access.
질문 # 142
A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A CloudOps engineer needs to keep the instances and all of the instances' data, even if someone deletes the stack.
Which solution will meet these requirements?
정답：D
설명：
When a CloudFormation stack is deleted, CloudFormation's default behavior is to delete the resources it created, including EC2 instances and attached resources defined in the template. The requirement is explicit:
the company must keep the instances and all of the instances' data even if someone deletes the stack. The CloudFormation mechanism intended for this outcome is the DeletionPolicy attribute, which controls what happens to a resource when the stack is deleted or when the resource is replaced during an update.
Setting DeletionPolicy: Retain on the EC2 instance resource instructs CloudFormation to preserve that resource instead of deleting it during stack deletion. With Retain, CloudFormation removes the resource from stack management but leaves the instance running (and therefore keeps the data that remains on the instance and its configured storage). This directly satisfies the requirement because the instance is not terminated as part of stack deletion.
Option A is incorrect for EC2 instances because Snapshot is applicable to certain resource types (commonly storage and database resources where snapshot semantics exist), not as a general "keep my instance" control for EC2 instance resources. Options B and C (DLM and AWS Backup) are valuable for backup and recovery strategies, but they do not prevent CloudFormation from terminating the instances when the stack is deleted.
Backups could help restore later, but the requirement is to keep the original instances and their data even after deletion of the stack.
Therefore, the correct solution is to set DeletionPolicy to Retain for the EC2 instance resource in the CloudFormation template.
질문 # 143
A company uses memory-optimized Amazon EC2 instances behind a Network Load Balancer (NLB) to run an application. The company launched the EC2 instances from an AWS-provided Red Hat Enterprise Linux (RHEL) AMI.
A CloudOps engineer must monitor RAM utilization in 5-minute intervals. The CloudOps engineer must ensure that the EC2 instances scale in and out appropriately based on incoming load.
Which solution will meet these requirements?
정답：A
설명：
EC2 does not publish RAM utilization as a native CloudWatch metric by default. Memory metrics such as mem_used_percent are typically collected by the CloudWatch Agent, which runs on the instance and publishes custom metrics to CloudWatch. Because the requirement is RAM utilization at 5-minute intervals, the CloudWatch Agent can be configured to emit metrics at that cadence (or faster).
"Detailed monitoring" for EC2 mainly affects EC2-provided metrics (like CPU) by changing the period from
5 minutes (basic) to 1 minute (detailed). It does not magically provide memory utilization. Therefore, the key requirement is installing/configuring the CloudWatch Agent and ensuring it has permissions to publish metrics (via an IAM role attached to the instance / instance profile).
Option C correctly combines: (1) basic monitoring (fine for the ask), (2) CloudWatch Agent to publish mem_used_percent, (3) IAM role permissions to allow publishing, and (4) Auto Scaling policy that scales based on the memory metric.
Option B incorrectly implies detailed monitoring provides mem_used_percent (it does not). Option D assumes a "standard" memory metric exists without the agent, which is not correct. Option A references mem_active, which is not the typical metric name exposed by CloudWatch Agent's standard memory measurements for scaling policies, and also omits the IAM role requirement needed for publishing custom metrics.
Thus, C is the AWS-correct path for memory-based scaling using CloudWatch custom metrics.
질문 # 144
A CloudOps engineer is responsible for a legacy, CPU-heavy application. The application can only be scaled vertically. Currently, the application is deployed on a single t3.large Amazon EC2 instance. The system is showing 90% CPU usage and significant performance latency after a few minutes.
What change should be made to alleviate the performance problem?
정답：B
설명：
The application is CPU-heavy, shows sustained high CPU utilization, and can only scale vertically. Therefore, the correct action is to move to a larger or more appropriate compute-optimized EC2 instance family. The current t3.large is a burstable general-purpose instance. Burstable instances can experience performance limitations if CPU credits are depleted after sustained high CPU usage, which matches the "after a few minutes" latency pattern. Provisioned IOPS helps storage-bound workloads, not CPU-bound workloads.
Adding more t3.large instances is horizontal scaling, which the question explicitly says the application cannot use. Reserved Instances reduce cost commitment but do not improve performance. A compute-optimized instance provides stronger sustained CPU capacity and is the correct performance optimization for a vertically scaled CPU-heavy workload.
