A company has been using the AW5 KMS service for managing its keys. They are planning on carrying out housekeeping activities and deleting keys which are no longer in use. What are the ways that can be incorporated to see which keys are in use? Choose 2 answers from the options given below
Please select:

Correct Answer:BC
The direct ways that can be used to see how the key is being used is to see the current access permissions and cloudtrail logs
Option A is invalid because seeing how long ago the key was created would not determine the usage of the key
Option D is invalid because Cloudtrail Event is better for seeing for events generated by the key This is also mentioned in the AWS Documentation
Examining CMK Permissions to Determine the Scope of Potential Usage
Determining who or what currently has access to a customer master key (CMK) might help you determine how widely the CM was used and whether it is still needed. To learn how to determine who or what currently has access to a CMK, go to Determining Access to an AWS KMS Customer Master Key.
Examining AWS CloudTrail Logs to Determine Actual Usage
AWS KMS is integrated with AWS CloudTrail, so all AWS KMS API activity is recorded in CloudTrail log files. If you have CloudTrail turned on in the region where your customer master key (CMK) is
located, you can examine your CloudTrail log files to view a history of all AWS KMS API activity for a particular CMK, and thus its usage history. You might be able to use a CMK's usage history to help you determine whether or not you still need it
For more information on determining the usage of CMK keys, please visit the following URL: https://docs.aws.amazon.com/kms/latest/developerguide/deleting-keys-determining-usage.html
The correct answers are: See who is assigned permissions to the master key. See Cloudtrail for usage of the key Submit your Feedback/Queries to our Experts

You are creating a Lambda function which will be triggered by a Cloudwatch Event. The data from these events needs to be stored in a DynamoDB table. How should the Lambda function be given access to the DynamoDB table?
Please select:

Correct Answer:B
AWS Lambda functions uses roles to interact with other AWS services. So use an 1AM role which has permissions to the DynamoDB table and attach it to the Lambda function.
Options A and C are all invalid because you should never use AWS keys for access. Option D is invalid because the VPC endpoint is used for VPCs
For more information on Lambda function Permission model, please visit the URL https://docs.aws.amazon.com/lambda/latest/dg/intro-permission-model.html
The correct answer is: Use an 1AM role which has permissions to the DynamoDB table and attach it to the Lambda function. Submit your Feedback/Queries to our Experts

A security engineer must ensure that all infrastructure launched in the company AWS account be monitored for deviation from compliance rules, specifically that all EC2 instances are launched from one of a specified list of AM Is and that all attached EBS volumes are encrypted. Infrastructure not in compliance should be terminated. What combination of steps should the Engineer implement? Select 2 answers from the options given below.
Please select:

Correct Answer:BD
You can use AWS Config to monitor for such Event
Option A is invalid because you cannot set Cloudwatch events based on Trusted Advisor checks.
Option C is invalid Amazon inspector cannot be used to check whether instances are launched from a specific A
Option E is invalid because triggering a CLI command is not the preferred option, instead you should use Lambda functions for all automation purposes.
For more information on Config Rules please see the below Link: https://docs.aws.amazon.com/config/latest/developerguide/evaluate-config-rules.html
These events can then trigger a lambda function to terminate instances For more information on Cloudwatch events please see the below Link: https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/WhatlsCloudWatchEvents.
(
The correct answers are: Trigger a Lambda function from a scheduled Cloudwatch event that terminates non-compliant infrastructure., Monitor compliance with AWS Config Rules triggered by configuration changes

How can you ensure that instance in an VPC does not use AWS DNS for routing DNS requests. You want to use your own managed DNS instance. How can this be achieved?
Please select:

Correct Answer:B
In order to use your own DNS server, you need to ensure that you create a new custom DHCP options set with the IP of th custom DNS server. You cannot modify the existing set, so you need to create a new one.
Option A is invalid because you cannot make changes to an existing DHCP options Set.
Option C is invalid because this can only be used to work with Routes and not with a custom DNS solution.
Option D is invalid because this needs to be done at the VPC level and not at the Subnet level For more information on DHCP options set, please visit the following url https://docs.aws.amazon.com/AmazonVPC/latest/UserGuideA/PC DHCP Options.html
The correct answer is: Create a new DHCP options set and replace the existing one. Submit your Feedback/Queries to our Experts

A company has a set of EC2 instances hosted in AWS. These instances have EBS volumes for storing critical information. There is a business continuity requirement and in order to boost the agility of the business and to ensure data durability which of the following options are not required.
Please select:

Correct Answer:CD
Data stored in Amazon EBS volumes is redundantly stored in multiple physical locations as part of normal operation of those services and at no additional charge. However, Amazon EBS replication is stored within the same availability zone, not across multiple zones; therefore, it is highly recommended that you conduct regular snapshots to Amazon S3 for long-term data durability.
You can use Amazon Data Lifecycle Manager (Amazon DLM) to automate the creation, retention, and deletion of snapshots
taken to back up your Amazon EBS volumes.
With lifecycle management, you can be sure that snapshots are cleaned up regularly and keep costs under control.
EBS Lifecycle Policies
A lifecycle policy consists of these core settings:
• Resource type—The AWS resource managed by the policy, in this case, EBS volumes.
• Target tag—The tag that must be associated with an EBS volume for it to be managed by the policy.
• Schedule—Defines how often to create snapshots and the maximum number of snapshots to keep. Snapshot creation starts within an hour of the specified start time. If creating a new snapshot exceeds the maximum number of snapshots to keep for the volume, the oldest snapshot is deleted.
Option C is correct. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. But it does not have an explicit feature like that.
Option D is correct Encryption does not ensure data durability

The correct answers are: Use EBS volume replication. Use EBS volume encryption Submit your Feedback/Queries to our Experts

You have just recently set up a web and database tier in a VPC and hosted the application. When testing the app , you are not able to reach the home page for the app. You have verified the security groups. What can help you diagnose the issue.
Please select:

Correct Answer:B
Option A is invalid because this can be used to check for security issues in your account, but not verify as to why you cannot reach the home page for your application
Option C is invalid because this used to protect your app against application layer attacks, but not verify as to why you cannot reach the home page for your application
Option D is invalid because this used to protect your instance against attacks, but not verify as to why you cannot reach the home page for your application
The AWS Documentation mentions the following
VPC Flow Logs capture network flow information for a VPC, subnet or network interface and stores it in Amazon CloudWatch Logs. Flow log data can help customers troubleshoot network issues; for example, to diagnose why specific traffic is not reaching an instance, which might be a result of overly restrictive security group rules. Customers can also use flow logs as a security toi to monitor the traffic that reaches their instances, to profile network traffic, and to look for abnormal traffic behaviors.

The correct answer is: Use VPC Flow logs to diagnose the traffic Submit your Feedback/Queries to our Experts
