What action should be performed to allow the ping to work?

Options:

In the security group of the EC2 instance, allow inbound ICMP traffic.

In the security group of the EC2 instance, allow outbound ICMP traffic.

In the VPC's NACL, allow inbound ICMP traffic.

In the VPC's NACL, allow outbound ICMP traffic.

Questions # 132:

Questions # 133:

A company wants to establish separate IAM Key Management Service (IAM KMS) keys to use for different IAM services. The company'ssecurityengineer created the following key policy lo allow the infrastructure deployment team to create encrypted Amazon Elastic Block Store (Amazon EBS) volumes by assuming the InfrastructureDeployment IAM role:

Question # 133

The security engineer recently discovered that IAM roles other than the InfrastructureDeployment role used this key (or other services. Which change to the policy should the security engineer make to resolve these issues?

Options:

In the statement block that contains the Sid "Allow use of the key", under the "Condition" block, change StringEquals to StringLike.

In the policy document, remove the statement Dlock that contains the Sid "Enable IAM User Permissions". Add key management policies to the KMS policy.

In the statement block that contains the Sid "Allow use of the Key", under the "Condition" block, change the Kms:ViaService value to ec2.us-east-1 .amazonIAM com.

In the policy document, add a new statement block that grants the kms:Disable' permission to the security engineer's IAM role.

Questions # 134:

A recent security audit found that IAM CloudTrail logs are insufficiently protected from tampering and unauthorized access Which actions must the Security Engineer take to address these audit findings? (Select THREE )

Options:

Ensure CloudTrail log file validation is turned on

Configure an S3 lifecycle rule to periodically archive CloudTrail logs into Glacier for long-term storage

Use an S3 bucket with tight access controls that exists m a separate account

Use Amazon Inspector to monitor the file integrity of CloudTrail log files.

Request a certificate through ACM and use a generated certificate private key to encrypt CloudTrail log files

Encrypt the CloudTrail log files with server-side encryption with IAM KMS-managed keys (SSE-KMS)

Questions # 135:

A company's policy requires that all API keys be encrypted and stored separately from source code in a centralized security account. This security account is managed by the company'ssecurity team However, an audit revealed that an API key is steed with the source code of an IAM Lambda function m an IAM CodeCommit repository in the DevOps account

How should the security learn securely store the API key?

Options:

Create a CodeCommit repository in the security account using IAM Key Management Service (IAM KMS) tor encryption Require the development team to migrate the Lambda source code to this repository

Store the API key in an Amazon S3 bucket in the security account using server-side encryption with Amazon S3 managed encryption keys (SSE-S3) to encrypt the key Create a resigned URL tor the S3 key. and specify the URL m a Lambda environmental variable in the IAM CloudFormation template Update the Lambda function code to retrieve the key using the URL and call the API

Create a secret in IAM Secrets Manager in the security account to store the API key using IAM Key Management Service (IAM KMS) tor encryption Grant access to the IAM role used by the Lambda function so that the function can retrieve the key from Secrets Manager and call the API

Create an encrypted environment variable for the Lambda function to store the API key using IAM Key Management Service (IAM KMS) tor encryption Grant access to the IAM role used by the Lambda function so that the function can decrypt the key at runtime

Questions # 136:

A company is processing data on AWS. The data is transmitted by millions of connected devices and is stored in Amazon RDS and Amazon DocumentDB (with MongoDB compatibility). The company uses AWS Backup to back up the data.

The company needs a solution to preserve individual backup recovery points Ail related data and metadata, such as character encodings and datatypes, must remain unchanged and protected from deletion. Retention times for the data will vary from several days to several years.

Which solution will meet these requirements?

Options:

Use AWS Backup to create legal holds for the recovery points.

Export the backup data to Amazon S3 Create S3 Object Lock legal holds for the recovery points.

Configure an AWS Backup Vault Lock in compliance mode.

Configure an AWS Backup Vault Lock in governance mode.

Questions # 137:

A company hosts an application on Amazon EC2 that is subject to specific rules for regulatory compliance. One rule states that traffic to and from the workload must be inspected for network-level attacks. This involves inspecting the whole packet.

To comply with this regulatory rule, a security engineer must install intrusion detection software on a c5n.4xlarge EC2 instance. The engineer must then configure the software to monitor traffic to and from the application instances.

What should the security engineer do next?

Options:

Place the network interface in promiscuous mode to capture the traffic.

Configure VPC Flow Logs to send traffic to the monitoring EC2 instance using a Network Load Balancer.

Configure VPC traffic mirroring to send traffic to the monitoring EC2 instance using a Network Load Balancer.

Use Amazon Inspector to detect network-level attacks and trigger an IAM Lambda function to send the suspicious packets to the EC2 instance.

Questions # 138:

A company’s public Application Load Balancer (ALB) recently experienced a DDoS attack. To mitigate this issue. the company deployed Amazon CloudFront in front of the ALB so that users would not directly access the Amazon EC2 instances behind the ALB.

The company discovers that some traffic is still coming directly into the ALB and is still being handled by the EC2 instances.

Which combination of steps should the company take to ensure that the EC2 instances will receive traffic only from CloudFront? (Choose two.)

Options:

Configure CloudFront to add a cache key policy to allow a custom HTTP header that CloudFront sends to the ALB.

Configure CloudFront to add a custom: HTTP header to requests that CloudFront sends to the ALB.

Configure the ALB to forward only requests that contain the custom HTTP header.

Configure the ALB and CloudFront to use the X-Forwarded-For header to check client IP addresses.

Configure the ALB and CloudFront to use the same X.509 certificate that is generated by AWS Certificate Manager (ACM).

Questions # 139:

A consultant agency needs to perform a security audit for a company's production AWS account. Several consultants need access to the account. The consultant agency already has its own AWS account.

The company requires multi-factor authentication (MFA) for all access to its production account. The company also forbids the use of long-term credentials.

Which solution will provide the consultant agency with access that meets these requirements?

Options:

Create an 1AM group. Create an 1AM user for each consultant. Add each user to the group. Turn on MFAfor each consultant.

Configure Amazon Cognito on the company's production account to authenticate against the consultant agency's identity provider (IdP). Add MFAto a Cognito user pool.

Create an 1AM role in the consultant agency's AWS account. Define a trust policy that requires MFA. In the trust policy, specify the company's production account as the principal. Attach the trust policy to the role.

Create an 1AM role in the company's production account. Define a trust policy that requires MFA. In the trust policy, specify the consultant agency's AWS account as the principal. Attach the trust policy to the role.

Questions # 140:

A company uses AWS Organizations to manage a small number of AWS accounts. However, the company plans to add 1 000 more accounts soon. The company allows only a centralized security team to create IAM roles for all AWS accounts and teams. Application teams submit requests for IAM roles to the security team. The security team has a backlog of IAM role requests and cannot review and provision the IAM roles quickly.

The security team must create a process that will allow application teams to provision their own IAM roles. The process must also limit the scope of IAM roles and prevent privilege escalation.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Create an IAM group for each application team. Associate policies with each IAM group. Provision IAM users for each application team member. Add the new IAM users to the appropriate IAM group by using role-based access control (RBAC).

Delegate application team leads to provision IAM rotes for each team. Conduct a quarterly review of the IAM rotes the team leads have provisioned. Ensure that the application team leads have the appropriate training to review IAM roles.

Put each AWS account in its own OU. Add an SCP to each OU to grant access to only the AWS services that the teams plan to use. Include conditions tn the AWS account of each team.

Create an SCP and a permissions boundary for IAM roles. Add the SCP to the root OU so that only roles that have the permissions boundary attached can create any new IAM roles.

Answer

Explanation

To create a process that will allow application teams to provision their own IAM roles, while limiting the scope of IAM roles and preventing privilege escalation, the following steps are required:

Create a service control policy (SCP) that defines the maximum permissions that can be granted to any IAM role in the organization. An SCP is a type of policy that you can use with AWS Organizations to manage permissions for all accounts in your organization. SCPs restrict permissions for entities in member accounts, including each AWS account root user, IAM users, and roles.For more information, see Service control policies overview.

Create a permissions boundary for IAM roles that matches the SCP. A permissions boundary is an advanced feature for using a managed policy to set the maximum permissions that an identity-based policy can grant to an IAM entity. A permissions boundary allows an entity to perform only the actions that are allowed by both its identity-based policies and its permissions boundaries.For more information, see Permissions boundaries for IAM entities.

Add the SCP to the root organizational unit (OU) so that it applies to all accounts in the organization. This will ensure that no IAM role can exceed the permissions defined by the SCP, regardless of how it is created or modified.

Instruct the application teams to attach the permissions boundary to any IAM role they create. This will prevent them from creating IAM roles that can escalate their own privileges or access resources they are not authorized to access.

This solution will meet the requirements with the least operational overhead, as it leverages AWS Organizations and IAM features to delegate and limit IAM role creation without requiring manual reviews or approvals.

The other options are incorrect because they either do not allow application teams to provision their own IAM roles (A), do not limit the scope of IAM roles or prevent privilege escalation (B), or do not take advantage of managed services whenever possible ©.
