A. Nothing
B. requests above your provisioned capacity will be performed but you will receive 400 error codes.
C. requests above your provisioned capacity will be performed but you will receive 200 error codes.
D. requests above your provisioned capacity will be throttled and you will receive 400 error codes.
Answer: D
Explanation:
Speaking about DynamoDB, if your application performs more reads/second or writes/second than your tabIe’s provisioned throughput capacity allows, requests above your provisioned capacity will be throttled and you will receive 400 error codes.

Q28. Does AWS CIoudFormation support Amazon EC2 tagging?
A. It depends if the Amazon EC2 tagging has been defined in the template.
B. No, it doesn’t support Amazon EC2 tagging.
C. No, CIoudFormation doesn’t support any tagging
D. Yes, AWS CIoudFormation supports Amazon EC2 tagging
Answer: D
Explanation:
In AWS CIoudFormation, Amazon EC2 resources that support the tagging feature can also be tagged in an AWS template.

Q29. A user has set an IAM policy where it allows all requests if a request from IP 10.10.10.1/32. Another policy allows all the requests between 5 PM to 7 PM. What will happen when a user is requesting access from IP 10.10.10.1/32 at 6 PM?
A. IAM will throw an error for policy conflict
B. It is not possible to set a policy based on the time or IP
C. It will deny access
D. It will allow access
Answer: D
Explanation:
With regard to IAM, when a request is made, the AWS service decides whether a given request should be allowed or denied. The evaluation logic follows these rules:
By default, all requests are denied. (In general, requests made using the account credentials for resources in the account are always allowed.)
An explicit allow policy overrides this default. An explicit deny policy overrides any allows. Reference:

Q30. Which one of the following statements is NOT an advantage of DyanamoDB being built on Solid State Drives:
A. serve high-scale request workloads
B. low request pricing
C. high I/O performance of WebApp on EC2 instance
D. low-latency response times
Answer: C
Explanation:
In DynamoDB, SSDs help achieve design goals of predictable low-latency response times for storing and accessing data at any scale. The high I/O performance of SSDs also enables to serve high-scale request workloads cost efficiently, and to pass this efficiency along in low request pricing.

Q31. Your manager has requested you to tag EC2 instances to orgAMze and manage a load balancer. Which of the following statements about tag restrictions is incorrect?
A. The maximum key length is 127 Unicode characters.
B. The maximum value length is 255 Unicode characters.
C. Tag keys and values are case sensitive.
D. The maximum number of tags per load balancer is 20.
Answer: D
Explanation:
Tags help you to categorize your load balancers in different ways, for example, by purpose, owner, or environment. The following basic restrictions apply to tags: The maximum number of tags per resource is
10. The maximum key length is 127 Unicode characters. The maximum value length that can be used is 255 Unicode characters. The tag keys and values are case sensitive. Allowed characters are letters, spaces, and numbers representable in UTF-8, plus the following special characters: + - =. _ : / @. Do not use leading or trailing spaces. Do not use the aws: prefix in your tag names or values because it is reserved for AWS use. You can't edit or delete tag names or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
