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

Your company has been using AWS for hosting EC2 Instances for their web and database applications. They want to have a compliance check to see the following
Whether any ports are left open other than admin ones like SSH and RDP
Whether any ports to the database server other than ones from the web server security group are
open Which of the following can help achieve this in the easiest way possible. You don't want to carry out an extra configuration changes?
Please select:
Correct Answer:B
Trusted Advisor checks for compliance with the following security recommendations:
Limited access to common administrative ports to only a small subset of addresses. This includes ports 22 (SSH), 23 (Telnet) 3389 (RDP), and 5500 (VNQ.
Limited access to common database ports. This includes ports 1433 (MSSQL Server), 1434 (MSSQL Monitor), 3306 (MySQL), Oracle (1521) and 5432 (PostgreSQL).
Option A is partially correct but then you would need to write custom rules for this. The AWS trusted advisor can give you all o these checks on its dashboard
Option C is incorrect. Amazon Inspector needs a software agent to be installed on all EC2 instances that are included in th.
assessment target, the security of which you want to evaluate with Amazon Inspector. It monitors the behavior of the EC2
instance on which it is installed, including network, file system, and process activity, and collects a wide set of behavior and
configuration data (telemetry), which it then passes to the Amazon Inspector service.
Our question's requirement is to choose a choice that is easy to implement. Hence Trusted Advisor is more appropriate for this )
question.
Options D is invalid because this service dont provide these details.

You need to create a Linux EC2 instance in AWS. Which of the following steps is used to ensure secure authentication the EC2 instance from a windows machine. Choose 2 answers from the options given below.
Please select:
Correct Answer:BC
The AWS Documentation mentions the following
You can use Amazon EC2 to create your key pair. Alternatively, you could use a third-party tool and then import the public key to Amazon EC2. Each key pair requires a name. Be sure to choose a name that is easy to remember. Amazon EC2 associates the public key with the name that you specify as the key name.
Amazon EC2 stores the public key only, and you store the private key. Anyone who possesses your private key can decrypt login information, so it's important that you store your private keys in a secure place.
Options A and D are incorrect since you should use key pairs for secure access to Ec2 Instances For more information on EC2 key pairs, please refer to below URL: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html
The correct answers are: Create a key pair using putty. Use the private key to log into the instance Submit your Feedback/Queries to our Experts
Your company uses AWS to host its resources. They have the following requirements
1) Record all API calls and Transitions
2) Help in understanding what resources are there in the account
3) Facility to allow auditing credentials and logins Which services would suffice the above requirements
Please select:
Correct Answer:C
You can use AWS CloudTrail to get a history of AWS API calls and related events for your account. This history includes calls made with the AWS Management Console, AWS Command Line Interface, AWS SDKs, and other AWS services.
Options A,B and D are invalid because you need to ensure that you use the services of CloudTrail, AWS Config, 1AM Credential Reports
For more information on Cloudtrail, please visit the below URL: http://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-user-guide.html
AWS Config is a service that enables you to assess, audit and evaluate the configurations of your AWS resources. Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. With Config, you can review changes in configurations and relationships between AWS resources, dive into detailed resource configuration histories, and determine your overall compliance against the configurations specified in your internal guidelines. This enables you to simplify compliance auditing, security analysis, char management and operational troubleshooting.

You can generate and download a credential report that lists all users in your account and the status of their various credentials, including passwords, access keys, and MFA devices. You can get a credential report from the AWS Management Console, the AWS SDKs and Command Line Tools, or the 1AM API.

Your company has just started using AWS and created an AWS account. They are aware of the potential issues when root access is enabled. How can they best safeguard the account when it comes to root access? Choose 2 answers fro the options given below
Please select:
Correct Answer:BD
The AWS Documentation mentions the following
All AWS accounts have root user credentials (that is, the credentials of the account owner). These credentials allow full access to all resources in the account. Because you cant restrict permissions for root user credentials, we recommend that you delete your root user access keys. Then create AWS Identity and Access Management (1AM) user credentials for everyday interaction with AWS. Option A is incorrect since you cannot delete the root access account
Option C is partially correct but cannot be used as the ideal solution for safeguarding the account For more information on root access vs admin 1AM users, please refer to below URL: https://docs.aws.amazon.com/eeneral/latest/er/root-vs-iam.html
The correct answers are: Create an Admin 1AM user with the necessary permissions. Delete the root access keys Submit your Feedback/Queries to our Experts
