Microsoft Azure Architect Design (AZ-301) Practice Exam

What type of certificates are necessary for users connecting to Azure applications via a point-to-site VPN?

1. A user certificate that has the public key

2. A user certificate that has the private key

3. A root CA certificate that has the public key

4. A root CA certificate that has the private key

The correct answer is: A root CA certificate that has the public key

In the context of connecting users to Azure applications through a point-to-site VPN, a root CA certificate with a public key is essential. This type of certificate is utilized to validate the identity of the user and establish a secure connection. When a user attempts to connect to the Azure VPN, the VPN client on the user's machine presents a user certificate to the Azure VPN gateway. The gateway must verify that this user certificate was issued by a trusted certificate authority (CA). The role of the root CA certificate here is to serve as the anchor of trust, meaning that it validates the entire chain of trust for the user certificate. By using a root CA certificate with a public key, the VPN gateway can check whether it trusts the user certificate. This public key allows the gateway to perform cryptographic operations necessary for ensuring the integrity and authenticity of the connection. Without this root CA certificate, the Azure VPN gateway would not have a reliable means of verifying the user's certificate, leading to possible security vulnerabilities. The other options do not apply correctly to this scenario. A user certificate that contains a private key is not meant to be shared and is used solely by the client for authentication. A CA certificate with a private key would typically not be distributed, as it could compromise the
