A Junos device is configured with a CA profile for an internal CA. The administrator needs to enroll for a certificate, but the enrollment process is failing. The administrator has verified that the CA profile is correctly configured and the CA is reachable. What is a likely cause of the enrollment failure?

The device's hostname is not configured.

The device's IP address is not in the CA's allow list.

The device's clock is not synchronized with the CA's clock.

The device's key pair is too large.

During certificate enrollment, what is the purpose of generating a key pair on the client device?

To generate the public key that will be included in the certificate request

To encrypt the certificate request so only the CA can read it

To provide the CA with the private key for safekeeping

To create a shared secret with the CA for encrypted communication

In a Public Key Infrastructure, which component is responsible for verifying the identity of an entity before a certificate is issued?

Certificate Revocation List (CRL)

Online Certificate Status Protocol (OCSP) responder

A Junos VPN gateway is configured to use certificates for IKE authentication. During IKE negotiation, the remote peer presents a certificate. The gateway verifies the certificate's validity period, trust chain, and revocation status. What is the purpose of these checks in the context of IPsec VPN authentication?

To encrypt the IKE negotiation traffic.

To select the IPsec encryption algorithm.

To ensure the remote peer's certificate is valid and trusted, thereby authenticating the peer.

To determine the IPsec security association (SA) lifetime.
