You are deploying a branch site which connects to two hub locations over an IPsec VPN. The branch SRX Series
device should send all traffic to the first hub unless it is unreachable and should then direct traffic to the
second hub. You must use static routes to send traffic towards the hub site.
Which two technologies should you use to fail over from a primary to a secondary tunnel in less than 60
seconds? (Choose two.)

A.
dead peer detection

B.
VPN monitoring

C.
floating static routes

D.
IP monitoring
