How do certificate updates propagate through a BIG-IP DNS sync group?

Through the SNMP trap mechanism.

Through the DNS zone transfer mechanism.

Through the configuration synchronization process.

Through the iControl REST API polling.

What is the purpose of generating a new key pair during device certificate renewal on a BIG-IP DNS device?

To ensure the certificate is cryptographically bound to the device's current identity.

To enable the certificate to be exported to other vendors' devices.

To allow the certificate to be used on multiple devices simultaneously.

To speed up the DNS resolution process.

An administrator needs to renew the device certificate on a BIG-IP DNS device. Which step is part of the renewal process?

Copy the certificate from another device in the sync group to avoid generating a new key.

Generate a new certificate signing request (CSR) and obtain a signed certificate from a CA.

Disable the DNS service before renewing the certificate to avoid downtime.

Delete the existing certificate from the device and rely on the sync group to recreate it.

After renewing a device certificate, the sync group shows a trust error. What is a basic troubleshooting step?

Disable the device's firewall temporarily.

Increase the sync group's timeout value.

Verify that all devices have the same certificate installed.

Restart the DNS service on all devices.

An administrator needs to renew the device certificate on a BIG-IP DNS device that is part of a sync group. The administrator wants to minimize downtime. What is the best approach?

Take the device offline, renew the certificate, and bring it back online.

Use a wildcard certificate to avoid future renewals.

Generate the new certificate and key, save the config, and perform a config sync during a maintenance window.

Renew the certificate on all devices simultaneously to avoid sync delays.
