NEW QUESTION 1
Your company has defined a number of EC2 Instances over a period of 6 months. They want to know if any of the security groups allow unrestricted access to a resource. What is the best option to accomplish this requirement?
Please select:
Answer: B
Explanation:
The AWS Trusted Advisor can check security groups for rules that allow unrestricted access to a resource. Unrestricted access increases opportunities for malicious activity (hacking, denial-of-service attacks, loss of data).
If you go to AWS Trusted Advisor, you can see the details C:UserswkDesktopmudassarUntitled.jpg
Option A is invalid because AWS Inspector is used to detect security vulnerabilities in instances and not for security groups.
Option C is invalid because this can be used to detect changes in security groups but not show you security groups that have compromised access.
Option Dis partially valid but would just be a maintenance overhead

NEW QUESTION 3
A company has resources hosted in their AWS Account. There is a requirement to monitor all API activity for all regions. The audit needs to be applied for future regions as well. Which of the following can be used to fulfil this requirement.
Please select:
Answer: B
Explanation:
The AWS Documentation mentions the following
You can now turn on a trail across all regions for your AWS account. CloudTrail will deliver log files from all regions to the Amazon S3 bucket and an optional CloudWatch Logs log group you specified. Additionally, when AWS launches a new region, CloudTrail will create the same trail in the new region. As a result you will receive log files containing API activity for the new region without taking any action.
Option A and C is invalid because this would be a maintenance overhead to enable cloudtrail for every region Option D is invalid because this AWS Config cannot be used to enable trails
For more information on this feature, please visit the following URL:
https://aws.ama2on.com/about-aws/whats-new/20l5/l2/turn-on-cloudtrail-across-all-reeions-and-support-for-mul The correct answer is: Ensure one Cloudtrail trail is enabled for all regions. Submit your Feedback/Queries to our Experts
NEW QUESTION 4
A Security Engineer must design a solution that enables the Incident Response team to audit for changes to a user’s IAM permissions in the case of a security incident.
How can this be accomplished?
Answer: A
NEW QUESTION 5
A Lambda function reads metadata from an S3 object and stores the metadata in a DynamoDB table. The function is triggered whenever an object is stored within the S3 bucket.
How should the Lambda function be given access to the DynamoDB table?
Please select:
Answer: D
Explanation:
The ideal way is to create an 1AM role which has the required permissions and then associate it with the Lambda function
The AWS Documentation additionally mentions the following
Each Lambda function has an 1AM role (execution role) associated with it. You specify the 1AM role when you create your Lambda function. Permissions you grant to this role determine what AWS Lambda can do when it assumes the role. There are two types of permissions that you grant to the 1AM role:
If your Lambda function code accesses other AWS resources, such as to read an object from an S3 bucket or write logs to CloudWatch Logs, you need to grant permissions for relevant Amazon S3 and CloudWatch actions to the role.
If the event source is stream-based (Amazon Kinesis Data Streams and DynamoDB streams), AWS Lambda polls these streams on your behalf. AWS Lambda needs permissions to poll the stream and read new records on the stream so you need to grant the relevant permissions to this role.
Option A is invalid because the VPC endpoint allows access instances in a private subnet to access DynamoDB
Option B is invalid because resources policies are present for resources such as S3 and KMS, but not AWS Lambda
Option C is invalid because AWS Roles should be used and not 1AM Users
For more information on the Lambda permission model, please visit the below URL: https://docs.aws.amazon.com/lambda/latest/dg/intro-permission-model.html
The correct answer is: Create an 1AM service role with permissions to write to the DynamoDB table. Associate that role with the Lambda function.

You have a requirement to conduct penetration testing on the AWS Cloud for a couple of EC2 Instances. How could you go about doing this? Choose 2 right answers from the options given below.
Please select:
Answer: AB
Explanation:
You can use a pre-approved solution from the AWS Marketplace. But till date the AWS Documentation still mentions that you have to get prior approval before conducting a test on the AWS Cloud for EC2 Instances.
Option C and D are invalid because you have to get prior approval first. AWS Docs Provides following details:
"For performing a penetration test on AWS resources first of all we need to take permission from AWS and complete a requisition form and submit it for approval. The form should contain information about the instances you wish to test identify the expected start and end dates/times of your test and requires you to read and agree to Terms and Conditions specific to penetration testing and to the use of appropriate tools for testing. Note that the end date may not be more than 90 days from the start date."

NEW QUESTION 9
A company is using a Redshift cluster to store their data warehouse. There is a requirement from the Internal IT Security team to ensure that data gets encrypted for the Redshift database. How can this be achieved?
Please select:
Answer: B
Explanation:
The AWS Documentation mentions the following
Amazon Redshift uses a hierarchy of encryption keys to encrypt the database. You can use either AWS Key Management Servic (AWS KMS) or a hardware security module (HSM) to manage the top-level encryption keys in this hierarchy. The process that Amazon Redshift uses for encryption differs depending on how you manage keys.
Option A is invalid because its the cluster that needs to be encrypted
Option C is invalid because this encrypts objects in transit and not objects at rest Option D is invalid because this is used only for objects in S3 buckets
For more information on Redshift encryption, please visit the following URL: https://docs.aws.amazon.com/redshift/latest/memt/workine-with-db-encryption.htmll
The correct answer is: Use AWS KMS Customer Default master key Submit your Feedback/Queries to our Experts
NEW QUESTION 10
You have a vendor that needs access to an AWS resource. You create an AWS user account. You want to restrict access to the resource using a policy for just that user over a brief period. Which of the following would be an ideal policy to use?
Please select:
Answer: B
Explanation:
The AWS Documentation gives an example on such a case
Inline policies are useful if you want to maintain a strict one-to-one relationship between a policy and the principal entity that if s applied to. For example, you want to be sure that the permissions in a policy are not inadvertently assigned to a principal entity other than the one they're intended for. When you use an inline policy, the permissions in the policy cannot be inadvertently attached to the wrong principal entity. In addition, when you use the AWS Management Console to delete that principal entit the policies embedded in the principal entity are deleted as well. That's because they are part of the principal entity.
Option A is invalid because AWS Managed Polices are ok for a group of users, but for individual users, inline policies are better.
Option C and D are invalid because they are specifically meant for access to S3 buckets For more information on policies, please visit the following URL: https://docs.aws.amazon.com/IAM/latest/UserGuide/access managed-vs-inline
The correct answer is: An Inline Policy Submit your Feedback/Queries to our Experts
NEW QUESTION 11
Your company has been using AWS for the past 2 years. They have separate S3 buckets for logging the various AWS services that have been used. They have hired an external vendor for analyzing their log files. They have their own AWS account. What is the best way to ensure that the partner account can access the log files in the company account for analysis. Choose 2 answers from the options given below
Please select:
Answer: BD
Explanation:
The AWS Documentation mentions the following
To share log files between multiple AWS accounts, you must perform the following general steps. These steps are explained in detail later in this section.
Create an 1AM role for each account that you want to share log files with.
For each of these 1AM roles, create an access policy that grants read-only access to the account you want to share the log files with.
Have an 1AM user in each account programmatically assume the appropriate role and retrieve the log files. Options A and C are invalid because creating an 1AM user and then sharing the 1AM user credentials with the
vendor is a direct 'NO' practise from a security perspective.
For more information on sharing cloudtrail logs files, please visit the following URL https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-sharine-loes.htmll
The correct answers are: Create an 1AM Role in the company account Ensure the 1AM Role has access for read-only to the S3 buckets

What is the recommended method to ensure that each application has its own programmatic access control permissions on the KMS CMK?
Answer: B
NEW QUESTION 16
A company is building a data lake on Amazon S3. The data consists of millions of small files containing sensitive information. The Security team has the following requirements for the architecture:
• Data must be encrypted in transit.
• Data must be encrypted at rest.
• The bucket must be private, but if the bucket is accidentally made public, the data must remain confidential. Which combination of steps would meet the requirements? (Choose two.)
Answer: BC
Explanation:
Bucket encryption using KMS will protect both in case disks are stolen as well as if the bucket is public. This is because the KMS key would need to have privileges granted to it for users outside of AWS.
NEW QUESTION 17
The Accounting department at Example Corp. has made a decision to hire a third-party firm, AnyCompany, to monitor Example Corp.'s AWS account to help optimize costs.
The Security Engineer for Example Corp. has been tasked with providing AnyCompany with access to the required Example Corp. AWS resources. The Engineer has created an IAM role and granted permission to AnyCompany's AWS account to assume this role.
When customers contact AnyCompany, they provide their role ARN for validation. The Engineer is concerned that one of AnyCompany's other customers might deduce Example Corp.'s role ARN and potentially compromise the company's account.
What steps should the Engineer perform to prevent this outcome?

NEW QUESTION 21
You have an EC2 instance with the following security configured:
a: ICMP inbound allowed on Security Group
b: ICMP outbound not configured on Security Group
c: ICMP inbound allowed on Network ACL
d: ICMP outbound denied on Network ACL
If Flow logs is enabled for the instance, which of the following flow records will be recorded? Choose 3 answers from the options give below
Please select:
Answer: ABD
Explanation:
This example is given in the AWS documentation as well
For example, you use the ping command from your home computer (IP address is 203.0.113.12) to your instance (the network interface's private IP address is 172.31.16.139). Your security group's inbound rules allow ICMP traffic and the outbound rules do not allow ICMP traffic however, because security groups are stateful, the response ping from your instance is allowed. Your network ACL permits inbound ICMP traffic but does not permit outbound ICMP traffic. Because network ACLs are stateless, the response ping is dropped and will not reach your home computer. In a flow log, this is displayed as 2 flow log records:
An ACCEPT record for the originating ping that was allowed by both the network ACL and the security group, and therefore was allowed to reach your instance.
A REJECT record for the response ping that the network ACL denied.
Option C is invalid because the REJECT record would not be present For more information on Flow Logs, please refer to the below URL:
http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/flow-loes.html
The correct answers are: An ACCEPT record for the request based on the Security Group, An ACCEPT record for the request based on the NACL, A REJECT record for the response based on the NACL

NEW QUESTION 22
A company wants to have a secure way of generating, storing and managing cryptographic exclusive access for the keys. Which of the following can be used for this purpose?
Please select:
Answer: D
Explanation:
The AWS Documentation mentions the following
The AWS CloudHSM service helps you meet corporate, contractual and regulatory compliance requirements for data security by using dedicated Hardware Security Module (HSM) instances within the AWS cloud. AWS and AWS Marketplace partners offer a variety of solutions for protecting sensitive data within the AWS platform, but for some applications and data subject to contractual or regulatory mandates for managing cryptographic keys, additional protection may be necessary. CloudHSM complements existing data protection solutions and allows you to protect your encryption keys within HSMs that are desigr and validated to government standards for secure key management. CloudHSM allows you to securely generate, store and manage cryptographic keys used for data encryption in a way that keys are accessible only by you.
Option A.B and Care invalid because in all of these cases, the management of the key will be with AWS. Here the question specifically mentions that you want to have exclusive access over the keys. This can be achieved with Cloud HSM

You want to have the ability to manage user profiles without having to add extra coding to manage this. Which of the below would assist in this.
Please select:
Answer: B
Explanation:
The AWS Documentation mentions the following The AWS Documentation mentions the following
OIDC identity providers are entities in 1AM that describe an identity provider (IdP) service that supports the OpenID Connect (OIDC) standard. You use an OIDC identity provider when you want to establish trust between an OlDC-compatible IdP—such as Google, Salesforce, and many others—and your AWS account This is useful if you are creating a mobile app or web application that requires access to AWS resources, but you don't want to create custom sign-in code or manage your own user identities
Option A is invalid because in the security groups you would not mention this information/ Option C is invalid because SAML is used for federated authentication
Option D is invalid because you need to use the OIDC identity provider in AWS For more information on ODIC identity providers, please refer to the below Link:
https://docs.aws.amazon.com/IAM/latest/UserGuide/id roles providers create oidc.htmll
The correct answer is: Create an OIDC identity provider in AWS
