QuestionQ21

High Availability

You need to add next-hop redundancy with VRRP for an IPv6-enabled service. The configured primary router must remain active whenever it is available, and servers attached to the network must be able to ping their gateway.

Which VRRP element is required to meet this requirement?

  • A The accept-data parameter must be added to the VRRP configuration.
  • B The preempt parameter must be added to the VRRP configuration.
  • C The backup router requires the track parameter to track the primary router's interface.
  • D Both routers running VRRP will require a static ARP entry to be configured for the VRRP VIP
Explanation

The accept-data setting enables the VRRP primary router to accept packets addressed to the virtual IP address, allowing connected servers to ping the virtual gateway. In Junos, a higher-priority backup router preempts a lower-priority primary by default, so explicitly adding preempt is not required for the preferred router to resume the primary role.
