Identify a true statement about the statement ID (Sid) in IAM.
Correct Answer:A
The Sid(statement ID) is an optional identifier that you provide for the policy statement. You can assign a Sid a value to each statement in a statement array. In IAM, the Sid is not exposed in the IAM API. You can't retrieve a particular statement based on this ID.

To get started using AWS Direct Connect, in which of the following steps do you configure Border Gateway Protocol (BGP)?
Correct Answer:C
In AWS Direct Connect, your network must support Border Gateway Protocol (BGP) and BGP MD5 authentication, and you need to provide a private Autonomous System Number (ASN) for that to connect to Amazon Virtual Private Cloud (VPC). To connect to public AWS products such as Amazon EC2 and Amazon S3, you will also need to provide a public ASN that you own (preferred) or a private ASN. You have to configure BGP in the Create a Virtual Interface step.
