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

Configure AWS Backup to create the backups according to the needed schedule. In the backup plan, specify multiple Availability Zones as backup destinations.

Configure Amazon Data Lifecycle Manager to create the backups. Configure the Amazon Data Lifecycle Manager policy to copy the backups to an Amazon S3 bucket. Enable replication on the S3 bucket.

Configure AWS Backup to create the backups according to the needed schedule. Create a destination backup vault in a different AWS Region. Configure AWS Backup to copy the backups to the destination backup vault.

Configure Amazon Data Lifecycle Manager to create the backups. Create an AWS Lambda function to copy the backups to a different AWS Region. Use Amazon EventBridge to invoke the Lambda function on a schedule.

Question # 62

Your company has a set of EC2 Instances defined in IAM. These Ec2 Instances have strict security groups attached to them. You need to ensure that changes to the Security groups are noted and acted on accordingly. How can you achieve this?

Please select:

Use Cloudwatch logs to monitor the activity on the Security Groups. Use filters to search for the changes and use SNS for the notification.

Use Cloudwatch metrics to monitor the activity on the Security Groups. Use filters to search for the changes and use SNS for the notification.

Use IAM inspector to monitor the activity on the Security Groups. Use filters to search for the changes and use SNS f the notification.

Use Cloudwatch events to be triggered for any changes to the Security Groups. Configure the Lambda function for email notification as well.

Question # 63

A security engineer needs to analyze Apache web server access logs that are stored in an Amazon S3 bucket. Amazon EC2 instance web servers generated the logs. The EC2 instances have the Amazon CloudWatch agent installed and configured to report their access logs.

The security engineer needs to use a query in Amazon Athena to analyze the logs. The query must identify IP addresses that have attempted and failed to access restricted web server content held at the /admin URL path. The query also must identify the URLs that the IP addresses attempted to access

Which query will meet these requirements?

Question # 64

A company is running an Amazon RDS for MySQL DB instance in a VPC. The VPC must not send or receive network traffic through the internet.

A security engineer wants to use AWS Secrets Manager to rotate the DB instance credentials automatically. Because of a security policy, the security engineer cannot use the standard AWS Lambda function that Secrets Manager provides to rotate the credentials.

The security engineer deploys a custom Lambda function in the VPC. The custom Lambda function will be responsible for rotating the secret in Secrets Manager. The security engineer edits the DB instance's security group to allow connections from this function. When the function is invoked, the function cannot communicate with Secrets Manager to rotate the secret properly.

What should the security engineer do so that the function can rotate the secret?

Add an egress-only internet gateway to the VPC. Allow only the Lambda function's subnet to route traffic through the egress-only internet gateway.

Add a NAT gateway to the VPC. Configure only the Lambda function's subnet with a default route through the NAT gateway.

Configure a VPC peering connection to the default VPC for Secrets Manager. Configure the Lambda function's subnet to use the peering connection for routes.

Configure a Secrets Manager interface VPC endpoint. Include the Lambda function's private subnet during the configuration process.

Answer:

Explanation:

You can establish a private connection between your VPC and Secrets Manager by creating an interface VPC endpoint. Interface endpoints are powered by AWS PrivateLink, a technology that enables you to privately access Secrets Manager APIs without an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Reference:https://docs.aws.amazon.com/secretsmanager/latest/userguide/vpc-endpoint-overview.html

The correct answer is D. Configure a Secrets Manager interface VPC endpoint. Include the Lambda function’s private subnet during the configuration process.

A Secrets Manager interface VPC endpoint is a private connection between the VPC and Secrets Manager that does not require an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection1. By configuring a Secrets Manager interface VPC endpoint, the security engineer can enable the custom Lambda function to communicate with Secrets Manager without sending or receiving network traffic through the internet.The security engineer must include the Lambda function’s private subnet during the configuration process to allow the function to use the endpoint2.

The other options are incorrect for the following reasons:

A.An egress-only internet gateway is a VPC component that allows outbound communication over IPv6 from instances in the VPC to the internet, and prevents the internet from initiating an IPv6 connection with the instances3. However, this option does not meet the requirement that the VPC must not send or receive network traffic through the internet.Moreover, an egress-only internet gateway is for use with IPv6 traffic only, and Secrets Manager does not support IPv6 addresses2.

B.A NAT gateway is a VPC component that enables instances in a private subnet to connect to the internet or other AWS services, but prevents the internet from initiating connections with those instances4. However, this option does not meet therequirement that the VPC must not send or receive network traffic through the internet.Additionally, a NAT gateway requires an elasticIP address, which is a public IPv4 address4.

C.A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses5. However, this option does not work because Secrets Manager does not have a default VPC that can be peered with.Furthermore, a VPC peering connection does not provide a private connection to Secrets Manager APIs without an internetgateway or other devices2.

Question # 65

A company's data scientists want to create artificial intelligence and machine learning (AI/ML) training models by using Amazon SageMaker. The training models will use large datasets in an Amazon S3 bucket. The datasets contain sensitive information.

On average. the data scientists need 30 days to train models. The S3 bucket has been secured appropriately The companfs data retention policy states that all data that is older than 45 days must be removed from the S3 bucket.

Which action should a security engineer take to enforce this data retention policy?

Configure an S3 Lifecycle rule on the S3 bucket to delete objects after 45 days.

Create an AWS Lambda function to check the last-modified date of the S3 objects and delete objects that are older than 45 days. Create an S3 event notification to invoke the Lambda function for each PutObject operation.

Create an AWS Lambda function to check the last-modified date of the S3 objects and delete objects that are older than 45 days. Create an Amazon EventBridge rule to invoke the Lambda function each month.

Configure S3 Intelligent-Ttering on the S3 bucket to automatically transition objects to another storage class.

Answer:

Explanation:

The correct answer is A. Configure an S3 Lifecycle rule on the S3 bucket to delete objects after 45 days.

The reason is that this is the simplest and most effective way to enforce the data retention policy.According to theAWS documentation1, “To manage your objects so that they are stored cost effectively throughout their lifecycle, configure their Amazon S3 Lifecycle. An S3 Lifecycle configuration is a set of rules that define actions that Amazon S3 applies to a group of objects.There are two types of actions: Transition actionsand Expiration actions.” The documentation1also states that “Expiration actions define when objects expire. Amazon S3 deletes expired objects on your behalf.” Therefore, by configuring an S3 Lifecycle rule on the S3 bucket to delete objects after 45 days, the security engineer can ensure that the data is removed from the S3 bucket according to the company’s policy.

The other options are incorrect because:

B. Create an AWS Lambda function to check the last-modified date of the S3 objects and delete objects that are older than 45 days. Create an S3 event notification to invoke the Lambda function for each PutObject operation. This option is not optimal because it requires deploying and maintaining a Lambda function, which adds complexity and cost. Moreover, it does not guarantee that the data is deleted exactly after 45 days, since the Lambda function is triggered only when a new object is put into the S3 bucket. If there are no new objects for a long period of time, the Lambda function will not run and the data will not be deleted.

C. Create an AWS Lambda function to check the last-modified date of the S3 objects and delete objects that are older than 45 days. Create an Amazon EventBridge rule to invoke the Lambda function each month. This option is not optimal because it requires deploying and maintaining a Lambda function, which adds complexity and cost. Moreover, it does not guarantee that the data is deleted exactly after 45 days, since the Lambda function is triggered only once a month. If the data is older than 45 days but less than a month, it will not be deleted until the next month.

D. Configure S3 Intelligent-Tiering on the S3 bucket to automatically transition objects to another storage class. This option is not sufficient to enforce the data retention policy, because it does not delete the data from the S3 bucket. It only moves the data to a less expensive storage class based on access patterns.According to the AWS documentation2, “S3 Intelligent-Tiering optimizes storage costs by automatically moving data between two access tiers, frequent access and infrequent access, when access patterns change.” However, this feature does not expire or delete the data after a certain period of time.

Question # 66

A company runs its microservices architecture in Kubernetes containers on AWS by using Amazon Elastic Kubemetes Service (Amazon EKS) and Amazon Aurora. The company has an organization in AWS Organizations to manage hundreds of AWS accounts that host different microservices.

The company needs to implement a monitoring solution for logs from all AWS resources across all accounts. The solution must include automatic detection of security-related issues.

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

Designate an Amazon GuardDuty administrator account in the organization's management account Enable GuardDuty for all accounts Enable EKS Protection and RDS Protection in the GuardDuty administrator account.

Designate a monitoring account Share Amazon CloudWatch logs from all accounts with the monitoring account Configure Aurora to publish all logs to CloudWatch Use Amazon Inspector in the monitoring account to evaluate the CloudWatch logs.

Create a central Amazon S3 bucket in the organization's management account Configure AWS CloudTrail in all AWS accounts to deliver CloudTrail logs to the S3 bucket Configure Aurora to publish all logs to CloudTrail Use Amazon Athena to query the CloudTrail logs in the S3 bucket for secunty issues.

Designate a monitoring account Share Amazon CloudWatch logs from all accounts with the monitoring account Subscnbe an Amazon Kinesis data stream to the CloudWatch logs Create AWS Lambda functions to process log records in the data stream to detect security issues.

Question # 67

A company uses AWS Organizations. The company has teams that use an AWS CloudHSM hardware security module (HSM) that is hosted in a central AWS account. One of the teams creates its own new dedicated AWS account and wants to use the HSM that is hosted in the central account.

How should a security engineer share the HSM that is hosted in the central account with the new dedicated account?

Use AWS Resource Access Manager (AWS RAM) to share the VPC subnet ID of the HSM that is hosted in the central account with the new dedicated account. Configure the CloudHSM security group to accept inbound traffic from the private IP addresses of client instances in the new dedicated account.

Use AWS Identity and Access Management (IAM) to create a cross-account rote to access the CloudHSM cluster that is in the central account Create a new IAM user in the new dedicated account Assign the cross-account rote to the new IAM user.

Use AWS 1AM Identity Center (AWS Single Sign-On) to create an AWS Security Token Service (AWS STS) token to authenticate from the new dedicated account to the central account. Use the cross-account permissions that are assigned to the STS token to invoke an operation on the HSM in the central account.

Use AWS Resource Access Manager (AWS RAM) to share the ID of the HSM that is hosted in the central account with the new dedicated account. Configure the CloudHSM security group to accept inbound traffic from the private IP addresses of client instances in the new dedicated account.

Question # 68

A company is running workloads in a single IAM account on Amazon EC2 instances and Amazon EMR clusters a recent security audit revealed that multiple Amazon Elastic Block Store (Amazon EBS) volumes and snapshots are not encrypted

The company's security engineer is working on a solution that will allow users to deploy EC2 Instances and EMR clusters while ensuring that all new EBS volumes and EBS snapshots are encrypted at rest. The solution must also minimize operational overhead

Which steps should the security engineer take to meet these requirements?

Create an Amazon Event Bridge (Amazon Cloud watch Events) event with an EC2 instanceas the source and create volume as the event trigger. When the event is triggered invoke an IAM Lambda function to evaluate and notify the security engineer if the EBS volume that was created is not encrypted.

Use a customer managed IAM policy that will verify that the encryptionﬂag of the Createvolume context is set to true. Apply this rule to all users.

Create an IAM Config rule to evaluate the conﬁguration of each EC2 instance on creation or modiﬁcation. Have the IAM Conﬁg rule trigger an IAM Lambdafunction to alert the security team and terminate the instance it the EBS volume is not encrypted. 5

Use the IAM Management Console or IAM CLi to enable encryption by default for EBS volumes in each IAM Region where the company operates.

Question # 69

A company uses Amazon EC2 Linux instances in the AWS Cloud. A member of the company's security team recently received a report about common vulnerability identifiers on the instances.

A security engineer needs to verify patching and perform remediation if the instances do not have the correct patches installed. The security engineer must determine which EC2 instances are at risk and must implement a solution to automatically update those instances with the applicable patches.

What should the security engineer do to meet these requirements?

Use AWS Systems Manager Patch Manager to view vulnerability identifiers for missing patches on the instances. Use Patch Manager also to automate the patching process.

Use AWS Shield Advanced to view vulnerability identifiers for missing patches on the instances. Use AWS Systems Manager Patch Manager to automate the patching process.

Use Amazon GuardDuty to view vulnerability identifiers for missing patches on the instances. Use Amazon Inspector to automate the patching process.

Use Amazon Inspector to view vulnerability identifiers for missing patches on the instances. Use Amazon Inspector also to automate the patching process.

Question # 70

A company's security engineer is designing an isolation procedure for Amazon EC2 instances as part of an incident response plan. The security engineer needs to isolate a target instance to block any traffic to and from the target instance, except for traffic from the company's forensics team. Each of the company's EC2 instances has its own dedicated security group. The EC2 instances are deployed in subnets of a VPC. A subnet can contain multiple instances.

The security engineer is testing the procedure for EC2 isolation and opens an SSH session to the target instance. The procedure starts to simulate access to the target instance by an attacker. The security engineer removes the existing security group rules and adds security group rules to give the forensics team access to the target instance on port 22.

After these changes, the security engineer notices that the SSH connection is still active and usable. When the security engineer runs a ping command to the public IP address of the target instance, the ping command is blocked.

What should the security engineer do to isolate the target instance?

Add an inbound rule to the security group to allow traffic from 0.0.0.0/0 for all ports. Add an outbound rule to the security group to allow traffic to 0.0.0.0/0 for all ports. Then immediately delete these rules.

Remove the port 22 security group rule. Attach an instance role policy that allows AWS Systems Manager Session Manager connections so that the forensics team can access the target instance.

Create a network ACL that is associated with the target instance's subnet. Add a rule at the top of the inbound rule set to deny all traffic from 0.0.0.0/0. Add a rule at the top of the outbound rule set to deny all traffic to 0.0.0.0/0.

Create an AWS Systems Manager document that adds a host-level firewall rule to block all inbound traffic and outbound traffic. Run the document on the target instance.
