A Junos device is configured to use a CRL for certificate revocation checking. The CRL is downloaded from the CA's distribution point. What is a potential limitation of using a CRL for revocation checking in a high-security environment?

CRLs are only available for certificates issued by a public CA.

CRLs cannot be used with certificates that have a validity period longer than one year.

CRLs are downloaded periodically, so there can be a delay between revocation and the next CRL download.

CRLs require the device to have a direct connection to the CA.

A financial services company is deploying IPsec VPNs between branch offices and a central data center. The security team wants to use certificates for IKE authentication instead of pre-shared keys. The company operates its own internal CA and has strict requirements that all certificates must be issued only after an employee manually approves each enrollment request. Which PKI component must be configured on the Junos devices to satisfy this requirement?

Enable OCSP on the Junos device for certificate validation.

Configure the Junos device to use an external Registration Authority (RA).

Set the certificate's key pair size to 4096 bits.

Configure a CA profile with an enrollment retry interval of 60 seconds.

A Junos VPN gateway is validating a certificate presented by a remote peer. The certificate is within its validity period, and the trust chain is valid. However, the gateway is configured to check for revocation. Which of the following must be true for the certificate to be considered valid?

The certificate must have a validity period of at least one year.

The certificate must be signed by the root CA directly.

The certificate must not appear on the CRL or be reported as revoked by OCSP.

The certificate must have a key usage extension that allows IPsec use.

A Junos device is enrolling for a certificate from an internal CA. The administrator has generated a key pair and created a CA profile. What is the next step in the enrollment process?

Configure the IPsec gateway to use the certificate.

What does 'trust chain verification' involve when validating a certificate?

Verifying each certificate in the chain up to a trusted root CA

Checking that the certificate's validity period has not expired

Confirming that the certificate has not been revoked via OCSP

Ensuring the certificate's public key matches the private key

Part of the Advanced IPsec VPNs domain, which makes up ~20% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 1–2 from this objective — we provide 19 practice questions to prepare you well beyond it.
