NEW QUESTION # 219
A company is running a containerized application on an Amazon Elastic Container Service (Amazon ECS) cluster that uses AWS Fargate. The application runs as several ECS services.
The ECS services are in individual target groups for an internet-facing Application Load Balancer (ALB). The ALB is the origin for an Amazon CloudFront distribution. An AWS WAF web ACL is associated with the CloudFront distribution.
Web clients access the ECS services through the CloudFront distribution. The company learns that the web clients can bypass the web ACL and can access the ALB directly.
Which solution will prevent the web clients from directly accessing the ALB?
Answer: C
Explanation:
When an internet-facing ALB is used as a CloudFront origin, it remains directly accessible unless additional access controls are enforced. According to AWS Certified Security - Specialty guidance, CloudFront IP allow lists alone are insufficient, because CloudFront IP ranges change and are not guaranteed to be exclusive.
The recommended and most secure approach is to configure CloudFront to send a custom origin header (such as X-Shared-Secret) with a secret value on every request to the origin. The ALB listener rules are then configured to forward traffic only when the header exists and matches the expected value. Requests that attempt to bypass CloudFront will not include this header and will be denied.
NEW QUESTION # 220
A company wants to deploy an application in a private VPC that will not be connected to the internet. The company's security team will not allow bastion hosts or methods using SSH to log in to Amazon EC2 instances. The application team plans to use AWS Systems Manager Session Manager to connect to and manage the EC2 instances.
Which combination of steps should the security team take? (Choose Three.)
Answer: A,C,D
Explanation:
Session Manager requires the target EC2 instance to be a managed node, which means Systems Manager Agent must be installed and running, and the instance profile must grant permissions for Systems Manager communication. In a private VPC with no internet connectivity, the instances need private connectivity to Systems Manager service endpoints through VPC interface endpoints. Depending on configuration, endpoints commonly include Systems Manager, EC2 messages, and Systems Manager messages; EC2 endpoint access can also be needed for related management operations. A NAT gateway would create internet- bound egress and conflicts with the private VPC requirement. A transit gateway does not provide AWS Systems Manager service connectivity by itself. Preventing SSH key pair creation is not required for Session Manager operation.
NEW QUESTION # 221
A company's developers are using AWS Lambda function URLs to invoke functions directly. The company must ensure that developers cannot configure or deploy unauthenticated functions inproduction accounts. The company wants to meet this requirement by using AWS Organizations. The solution must not require additional work for the developers.
Which solution will meet these requirements?
Answer: A
Explanation:
AWS Organizations service control policies (SCPs) are designed to enforce preventive guardrails across accounts without requiring application-level changes. According to the AWS Certified Security - Specialty documentation, SCPs can restrict specific API actions or require certain condition keys to enforce security standards centrally. AWS Lambda function URLs support two authentication modes: AWS_IAM and NONE.
When the authentication type is set to NONE, the function URL becomes publicly accessible, which introduces a significant security risk in production environments.
By using an SCP that explicitly denies the lambda:CreateFunctionUrlConfig and lambda:
UpdateFunctionUrlConfig actions when the lambda:FunctionUrlAuthType condition key equals NONE, the organization ensures that unauthenticated function URLs cannot be created or modified in production accounts. This enforcement occurs at the AWS Organizations level and applies automatically to all accounts within the specified organizational units (OUs). Developers are not required to change their workflows or add additional controls, satisfying the requirement of no additional developer effort.
Option A relates to browser-based access controls and does not provide authentication or authorization enforcement. Option B is not valid because AWS WAF cannot be attached directly to AWS Lambda function URLs. Option C is incorrect because SCPs do not grant permissions; they only limit permissions. AWS documentation clearly states that SCPs define maximum available permissions and are evaluated before IAM policies.
This approach aligns with AWS best practices for centralized governance, least privilege, and preventive security controls.

NEW QUESTION # 222
A company must capture AWS CloudTrail data events and must retain the logs for 7 years. The logs must be immutable and must be available to be searched by complex queries. The company also needs to visualize the data from the logs.
Which solution will meet these requirements MOST cost-effectively?
Answer: A
Explanation:
AWS CloudTrail Lake is purpose-built to store, query, and analyze CloudTrail events, including data events, without requiring additional infrastructure. The AWS Certified Security - Specialty documentation explains that CloudTrail Lake provides immutable event storage with configurable retention periods, including multi- year retention, which satisfies long-term compliance requirements such as 7-year retention. Events are stored in an append-only, immutable format managed by AWS, reducing operational complexity.
CloudTrail Lake supports SQL-based queries for complex analysis directly against the event data, eliminating the need to export logs to other services for querying. Additionally, CloudTrail Lake includes built-in dashboards and integrations that enable visualization of event trends and patterns without standing up separate analytics or visualization platforms.
Option B is invalid because CloudTrail Event History only retains events for up to 90 days and does not support long-term retention or advanced querying. Option C introduces high operational overhead and cost by requiring persistent Amazon EMR clusters and additional services. Option D incurs ongoing ingestion, indexing, and storage costs for OpenSearch Service over a 7-year period, making it less cost-effective than CloudTrail Lake.
AWS documentation positions CloudTrail Lake as the most cost-effective and operationally efficient solution for long-term, queryable CloudTrail event storage and visualization.

NEW QUESTION # 223
A company runs critical workloads in an on-premises data center. The company wants to implement an AWS based disaster recovery (DR) solution that will achieve an RTO of less than 1 hour. The company needs to continuously replicate physical and virtual servers. The company must optimize costs for data storage and bandwidth usage. The DR solution must be automated.
Which solution will meet these requirements?
Answer: D
Explanation:
AWS Elastic Disaster Recovery (AWS DRS)is purpose-built for continuously replicatingphysical and virtual serversinto AWS with low RTO/RPO. It uses lightweight replication agents to stream block- level changes to a low-coststaging areain AWS, which helps optimize storage costs (only the staging resources run continuously) and reduces bandwidth usage through efficient replication mechanisms. In a disaster or test, AWS DRS can automatically launch recovery instances in AWS based on a defined blueprint (instance types, networking, security groups), enabling rapid failover workflows that commonly meetsub-hour RTOobjectives.
