You are planning the configuration for IPMP (IP Multipathing).

Best practice dictates that you must ensure that there is at least one neighbor on each subnet that responds to ICMP echo request probes to detect link failure

Which two of the following statements are true regarding the link failure detection process? (Choose two.)

ABy default, in.mpathd selects the default router as the only test partner.

BThe default failure detection time is 60 seconds (12 consecutive probes).

CWithout test partners, in.mpathd cannot detect the failure of a subinterface.

DArbitrary hosts on the subnet are detected by sending an 'all hosts' (224.0.0.1) multicast packet

EArbitrary hosts on the subnet are detected by sending an 'all routers' (224.0.0.2) multicast packet.

FArbitrary hosts on the subnet are detected by examining the ARP cache (Internet-to-MAC address translation table).

As for options D and E, I believe they are not true. The correct way to detect arbitrary hosts on the subnet is through examining the ARP cache, like option F suggests.
