Question 39 - NCP-CI-AWS discussion

Report
Export

An administrator is experiencing problems with several operations, including VM IP address assignment validations, VM power-on and VM power-off operations.

Whenever a related operation is performed, an alert is generated in the NC2 console indicating that the Cloud API endpoints are unavailable.

The issue was further investigated and it was determined that NC2 is unable to make API calls to the underlying cloud infrastructure due to network connectivity misconfigurations.

Which two connectivity misconfigurations could be causing this issue? (Choose two.)

A.
AWS VPC endpoints are used for connectivity to AWS services.
Answers

Answers

C.
Route tables for cloud subnets contain incorrect route entries.
Answers
C.
Route tables for cloud subnets contain incorrect route entries.
D.
IAM roles and policies are incorrectly configured.
Answers
D.
IAM roles and policies are incorrectly configured.
Suggested answer: C, D

Explanation:

Route tables for cloud subnets contain incorrect route entries:

If the route tables associated with the cloud subnets contain incorrect route entries, the NC2 cluster might not be able to reach the necessary AWS services or endpoints. Correct route entries are crucial for ensuring proper communication between the NC2 cluster and the underlying AWS infrastructure.

IAM roles and policies are incorrectly configured:

Incorrectly configured IAM roles and policies can prevent NC2 from making API calls to AWS services. These roles and policies must be properly set up to allow the necessary permissions for NC2 to interact with AWS resources and perform required operations.

Reference: Refer to the AWS documentation on route table configuration and IAM roles and policies, and Nutanix documentation on NC2 cloud connectivity and permissions.
