A. B. C. D.Answer - C.
This command will give you the entire details about your instance which includes the subnet, VPC and security group associated with your instance.
For more information on the command, please visit the below URL:
http://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instances.htmlThe command that you would use to find the subnet, the security group, and the VPC associated with your instance would be "AWS ec2 describe-instances". This command provides information about the specified instances or all instances within the specified filters.
Option A, "AWS vpc describe-all", provides information about all VPCs in the account. While it could be useful to find the VPC associated with the instance, it would not provide information on the subnet or security group.
Option B, "AWS ec2 describe-security-groups", provides information about the specified security groups or all security groups in the account. While it could be useful to find the security group associated with the instance, it would not provide information on the subnet or VPC.
Option D, "AWS ec2 describe-network-acl", provides information about the specified network ACL or all network ACLs in the account. While it could be useful to find the subnet associated with the instance, it would not provide information on the security group or VPC.
Therefore, the correct command to use in this scenario would be "AWS ec2 describe-instances". Once you have the instance ID, you can use this command to retrieve information about the instance, including the subnet, security group, and VPC it is associated with.
