An LTM administrator is configuring a device group for high availability. The administrator wants the standby device to have the same health-check status as the active device. What must be configured to ensure this?

Enable iQuery on both devices and add them to the same device group.

Set up a DNS zone transfer between the devices.

Configure the same health monitors on both devices.

Use the same virtual server IP on both devices.

In a BIG-IP DNS sync group, what is the primary role of iQuery?

To manage DNS zone transfers between primary and secondary DNS servers

To provide a secure channel for devices in the sync group to exchange configuration and synchronization data

To encrypt all DNS queries between the BIG-IP DNS and external DNS servers

To monitor the health of backend servers using ICMP probes

A BIG-IP LTM device is part of a device group that includes a second LTM device. The administrator notices that the second device is not reflecting the health status of pool members. The devices are in the same data center and can communicate. What is the most likely reason for this?

iQuery is not enabled on one of the devices.

The second device has a different DNS configuration.

The virtual server is not assigned to a sync group.

The pool members are not in the same VLAN.

An organization is adding a new BIG-IP DNS device to an existing sync group. The administrator has configured device trust and verified network connectivity. What is the next step to add the device to the sync group?

Create a new DNS zone on the new device.

Reboot the new device to apply the trust settings.

Add the device to the sync group from the BIG-IP DNS configuration utility.

Change the management IP of the new device to match the existing devices.
