- B. Modify the IAM policy on the user to require MFA before deleting EC2 instances and disable MFA access to the employee
- C. Modify the IAM policy on the user to require MFA before deleting EC2 instances
- D. Tag the instance with a production-identifying tag and add resource-level permissions to the employee user with an explicit deny on the terminate API call to instances with the production tag. <
Answer: A,D
Explanation:
Tags enable you to categorize your AWS resources in different ways, for example, by purpose, owner, or environment. This is useful when you have many resources of the same type - you can quickly identify a specific resource based on the tags you've assigned to it. Each tag consists of a key and an optional value, both of which you define Options C&D are incorrect because it will not ensure that the employee cannot terminate the instance.

NEW QUESTION 62
DDoS attacks that happen at the application layer commonly target web applications with lower volumes of traffic compared to infrastructure attacks. To mitigate these types of attacks, you should probably want to include a WAF (Web Application firewall) as part of your infrastructure. To inspect all HTTP requests, WAFs sit in-line with your application traffic. Unfortunately, this creates a scenario where WAFs can become a point of failure or bottleneck. To mitigate this problem, you need the ability to run multiple WAFs on demand during traffic spikes. This type of scaling for WAF is done via a "WAF sandwich." Which of the following statements best describes what a "WAF sandwich" is? Choose the correct answer from the options below
Please select:
- A. The EC2 instance running your WAF software is placed between your public subnets and your Internet Gateway.
- B. The EC2 instance running your WAF software is included in an Auto Scaling group and placed in between two Elastic load balancers.
- C. The EC2 instance running your WAF software is placed between your private subnets and any NATed connections to the internet.
- D. The EC2 instance running your WAF software is placed between your public subnets and your private subnets.
Answer: B
Explanation:
The below diagram shows how a WAF sandwich is created. Its the concept of placing the Ec2 instance which hosts the WAF software in between 2 elastic load balancers.
Option A.B and C are incorrect since the EC2 Instance with the WAF software needs to be placed in an Autoscaling Group For more information on a WAF sandwich please refer to the below Link:
https://www.cloudaxis.eom/2016/11/2l/waf-sandwich/l

A company stores critical data in an S3 bucket. There is a requirement to ensure that an extra level of security is added to the S3 bucket. In addition , it should be ensured that objects are available in a secondary region if the primary one goes down. Which of the following can help fulfil these requirements? Choose 2 answers from the options given below Please select:
- A. Enable the Bucket ACL and add a condition for {"Null": {"aws:MultiFactorAuthAge": true}}
- B. Enable bucket versioning and also enable CRR
- C. Enable bucket versioning and enable Master Pays
- D. For the Bucket policy add a condition for {"Null": {"aws:MultiFactorAuthAge": true}} i
Answer: B,D
Explanation:
Explanation
The AWS Documentation mentions the following
Adding a Bucket Policy to Require MFA
Amazon S3 supports MFA-protected API access, a feature that can enforce multi-factor authentication (MFA) for access to your Amazon S3 resources. Multi-factor authentication provides an extra level of security you can apply to your AWS environment. It is a security feature that requires users to prove physical possession of an MFA device by providing a valid MFA code. For more information, go to AWS Multi-Factor Authentication. You can require MFA authentication for any requests to access your Amazoi. S3 resources.
You can enforce the MFA authentication requirement using the aws:MultiFactorAuthAge key in a bucket policy. IAM users car access Amazon S3 resources by using temporary credentials issued by the AWS Security Token Service (STS). You provide the MFA code at the time of the STS request.
When Amazon S3 receives a request with MFA authentication, the aws:MultiFactorAuthAge key provides a numeric value indicating how long ago (in seconds) the temporary credential was created. If the temporary credential provided in the request was not created using an MFA device, this key value is null (absent). In a bucket policy, you can add a condition to check this value, as shown in the following example bucket policy.
The policy denies any Amazon S3 operation on the /taxdocuments folder in the examplebucket bucket if the request is not MFA authenticated. To learn more about MFA authentication, see Using Multi-Factor Authentication (MFA) in AWS in the IAM User Guide.
Option B is invalid because just enabling bucket versioning will not guarantee replication of objects Option D is invalid because the condition for the bucket policy needs to be set accordingly For more information on example bucket policies, please visit the following URL: *
https://docs.aws.amazon.com/AmazonS3/latest/dev/example-bucket-policies.html Also versioning and Cross Region replication can ensure that objects will be available in the destination region in case the primary region fails.
For more information on CRR, please visit the following URL:
https://docs.aws.amazon.com/AmazonS3/latest/dev/crr.html
The correct answers are: Enable bucket versioning and also enable CRR, For the Bucket policy add a condition for {"Null": { "aws:MultiFactorAuthAge": true}} Submit your Feedback/Queries to our Experts
