Question # 71

A company has a new web-based account management system for an online game Players create a unique username and password to log in to the system.

The company has implemented an AWS WAF web ACL for the system. The web ACL includes the core rule set (CRS) AWS managed rule group on the Application Load Balancer that serves the system.

The company's security team finds that the system was the target of a credential stuffing attack Credentials that were exposed in other breaches were used to try to log in to the system

The security team must implement a solution to reduce the chance of a successful credential stuffing attack in the future The solution also must minimize impact on legitimate users of the system

Which combination of actions will meet these requirements? (Select TWO.)

Create an Amazon CloudWatch custom metric to analyze the number of successful login responses from a single IP address

Add the account takeover prevention (ATP) AWS managed rule group to the web ACL Configure the rule group to inspect login requests to the system Block any requests that have the awswaf managed awsatp signal credential_compromised label

Configure a default web ACL action that requires all users to solve a CAPTCHA puzzle when they log in

Implement IP-based match rules in the web ACL for any IP addresses that generate many successful login responses Block any IP addresses that generate many successful logins

Create a custom block response that redirects users to a secure workflow to reset their password inside the system

Question # 72

A company needs to use HTTPS when connecting to its web applications to meet compliance requirements. These web applications run in Amazon VPC on Amazon EC2 instances behind an Application Load Balancer (ALB). A security engineer wants to ensure that the load balancer win only accept connections over port 443. even if the ALB is mistakenly configured with an HTTP listener

Which configuration steps should the security engineer take to accomplish this task?

Create a security group with a rule that denies Inbound connections from 0.0.0 0/0 on port 00. Attach this security group to the ALB to overwrite more permissive rules from the ALB's default securitygroup.

Create a network ACL that denies inbound connections from 0 0.0.0/0 on port 80 Associatethe network ACL with the VPC s internet gateway

Create a network ACL that allows outbound connections to the VPC IP range on port 443 only. Associate the network ACL with the VPC's internet gateway.

Create a security group with a single inbound rule that allows connections from 0.0.0 0/0 on port 443. Ensure this security group is the only one associated with the ALB

Question # 73

A security engineer needs to configure an Amazon S3 bucket policy to restrict access to an S3 bucket that is named DOC-EXAMPLE-BUCKET. The policy must allow access to only DOC-EXAMPLE-BUCKET from only the following endpoint: vpce-1a2b3c4d. The policy must deny all access to DOC-EXAMPLE-BUCKET if the specified endpoint is not used.

Which bucket policy statement meets these requirements?

A computer code with black text Description automatically generated

Question # 74

An AWS account includes two S3 buckets: bucketl and bucket2. The bucket2 does not have a policy defined, but bucketl has the following bucket policy:

In addition, the same account has an 1AM User named "alice", with the following 1AM policy.

Which buckets can user "alice" access?

bucketl only

bucket2 only

Both bucketl and bucket2

Neither bucketl nor bucket2

Question # 75

An application is running on an Amazon EC2 instance that has an IAM role attached. The IAM role provides access to an AWS Key Management Service (AWS KMS) customer managed key and an Amazon S3 bucket. The key is used to access 2 TB of sensitive data that is stored in the S3 bucket.

A security engineer discovers a potential vulnerability on the EC2 instance that could result in the compromise of the sensitive data. Due to other critical operations, the security engineer cannot immediately shut down the EC2 instance for vulnerability patching.

What is the FASTEST way to prevent the sensitive data from being exposed?

Download the data from the existing S3 bucket to a new EC2 instance. Then delete the data from the S3 bucket. Re-encrypt the data with a client-based key. Upload the data to a new S3 bucket.

Block access to the public range of S3 endpoint IP addresses by using a host-based firewall. Ensure that internet-bound traffic from the affected EC2 instance is routed through the host-based firewall.

Revoke the IAM role's active session permissions. Update the S3 bucket policy to deny access to the IAM role. Remove the IAM role from the EC2 instance profile.

Disable the current key. Create a new KMS key that the IAM role does not have access to, and re-encrypt all the data with the new key. Schedule the compromised key for deletion.

Question # 76

A company operates a web application that runs on Amazon EC2 instances. The application listens on port 80 and port 443. The company uses an Application Load Balancer (ALB) with AWS WAF to terminate SSL and to forward traffic to the application instances only on port 80.

The ALB is in public subnets that are associated with a network ACL that is named NACL1. The application instances are in dedicated private subnets that are associated with a network ACL that is named NACL2. An Amazon RDS for PostgreSQL DB instance that uses port 5432 is in a dedicated private subnet that is associated with a network ACL that is named NACL3. All the network ACLs currently allow all inbound and outbound traffic.

Which set of network ACL changes will increase the security of the application while ensuring functionality?

Make the following changes to NACL3:• Add a rule that allows inbound traffic on port 5432 from NACL2.• Add a rule that allows outbound traffic on ports 1024-65536 to NACL2.• Remove the default rules that allow all inbound and outbound traffic.

Make the following changes to NACL3:• Add a rule that allows inbound traffic on port 5432 from the CIDR blocks of the application instance subnets.• Add a rule that allows outbound traffic on ports 1024-65536 to the application instance subnets.• Remove the default rules that allow all inbound and outbound traffic.

Make the following changes to NACL2:• Add a rule that allows outbound traffic on port 5432 to the CIDR blocks of the RDS subnets.• Remove the default rules that allow all inbound and outbound traffic.

Make the following changes to NACL2:• Add a rule that allows inbound traffic on port 5432 from the CIDR blocks of the RDS subnets.• Add a rule that allows outbound traffic on port 5432 to the RDS subnets.

Question # 77

A company wants to deploy a distributed web application on a fleet of EC2 instances. The fleet will be fronted by a Classic Load Balancer that will be configured to terminate the TLS connection The company wants to make sure that all past and current TLS traffic to the Classic Load Balancer stays secure even if the certificate private key is leaked.

To ensure the company meets these requirements, a Security Engineer can configure a Classic Load Balancer with:

An HTTPS listener that uses a certificate that is managed by Amazon Certification Manager.

An HTTPS listener that uses a custom security policy that allows only perfect forward secrecy cipher suites

An HTTPS listener that uses the latest IAM predefined ELBSecuntyPolicy-TLS-1 -2-2017-01 security policy

A TCP listener that uses a custom security policy that allows only perfect forward secrecy cipher suites.

Question # 78

A company uses an organization in AWS Organizations to manage hundreds of AWS accounts. Some of the accounts provide access to external AWS principals through cross-account IAM roles and Amazon S3 bucket policies.

The company needs to identify which external principals have access to which accounts.

Which solution will provide this information?

Enable AWS Identity and Access Management Access Analyzer for the organization. Configure the organization as a zone of trust. Filter findings by AWS account ID.

Create a custom AWS Config rule to monitor IAM roles in each account. Deploy an AWS Config aggregator to a central account. Filter findings by AWS account ID.

Activate Amazon Inspector. Integrate Amazon Inspector with AWS Security Hub. Filter findings by AWS account ID for the last role resource type and the S3 bucket policy resource type.

Configure the organization to use Amazon GuardDuty. Filter findings by AWS account ID for the Discovery:IAMUser/AnomalousBehavior finding type.

Question # 79

A company runs an application on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). A security engineer needs to provide secure access to the application without requiring the use of a VPN. Users should be able to access the application only when they meet specific security conditions including a defined device posture.

Which solution will meet these requirements'?

Create an AWS WAF web ACL Configure a custom response to block traffic that does not align with the defined device posture

Configure AWS Verified Access Add the application by creating an endpoint for the ALB

Configure Amazon Verified Permissions Use a policy-based access control (PBAC) policy to perform authorization

Configure Amazon Verified Permissions Add the application by creating an endpoint for the ALB.

Question # 80

A company's application team needs to host a MySQL database on IAM. According to the company's security policy, all data that is stored on IAM must be encrypted at rest. In addition, all cryptographic material must be compliant with FIPS 140-2 Level 3 validation.

The application team needs a solution that satisfies the company's security requirements and minimizes operational overhead.

Which solution will meet these requirements?

Host the database on Amazon RDS. Use Amazon Elastic Block Store (Amazon EBS) for encryption. Use an IAM Key Management Service (IAM KMS) custom key store that is backed by IAM CloudHSM for key management.

Host the database on Amazon RDS. Use Amazon Elastic Block Store (Amazon EBS) for encryption. Use an IAM managed CMK in IAM Key Management Service (IAM KMS) for key management.
