A department in your company has created a new account that is not part of the organization's consolidated billing family.

The department has also created a VPC for its workload. Access is restricted by network access control lists to the department's on-premises private IP allocation.

All IP addresses within a 10.0.0.0/16 VPC are fully utilized with application servers across two Availability Zones. The application servers need to send frequent UDP probes to a single central authentication server on the Internet to confirm that it is running up-to-date packages. The network is designed for application servers to use a single NAT gateway for internal access. Testing reveals that a few of the servers are unable to communicate with the authentication server. What is the reason for this failure?

A.
The NAT gateway does not support UDP traffic.

A customer has set up multiple VPCs for Dev, Test, Prod, and Management. You need to set up AWS Direct Connect to enable data flow from on-premises to each VPC. The customer has monitoring software running in the Management VPC that collects metrics from the instances in all the other VPCs. Due to budget requirements, data transfer charges should be kept at minimum. Which design should be recommended?

A.
Create a total of four private VIFs, one for each VPC owned by the customer, and route traffic between VPCs using the Direct Connect link.

D.
For the period when there is no data the user should send a blank value
D.
For the period when there is no data the user should send a blank value
Answers
Suggested answer: C

Explanation:

Explanation:

AWS CloudWatch supports the custom metrics. The user can always capture the custom data and upload the data to CloudWatch using CLI or APIs. When the user data is more random and not generated at regular intervals, there can be a period which has no associated data. The user can either publish the zero (0) value for that period or not publish the data at all. It is recommended that the user should publish zero instead of no value to monitor the health of the application. This is helpful in an alarm as well as in the generation of the sample data count.

Explanation:

Explanation:

The JSON object for an AWS Config event contains a ruleParameters attribute, which is a set of key/value pairs that the AWS Lambda function receiving the event processes as part of its evaluation logic. You define parameters when you use the AWS Config console to create a custom rule. You can also define parameters with the InputParameters attribute in the PutConfigRule AWS Config API request or the put-config-rule AWS CLI command. The JSON code for the parameters is contained within a string, so a function must parse the string with a JSON parser to be able to evaluate its contents Reference: http://docs.aws.amazon.com/config/latest/developerguide/evaluate-config_develop-rules_exa mple-events.html
