You want to deploy an SRX Series cluster for a distributed data center between two remote locations. The earner will provide you with dark fiber capable of the following: a 100 km reach. 125ms propagation delay, and a packet loss of 1 out of 10.000.000 packets. You plan to connect the fiber directly to the SRX Series devices without any switches in between, and you plan to configure the SRX Series devices with a straightforward cluster configuration. One of the NOC engineers expresses doubts that this design will work.
How do you respond?
A.
You explain that everything will work as expected.
B.
You agree to install switches in between the SRX Series clusters in both sites for increased availability of the network.
C.
You agree with the argument that dark fiber is not the best choice and choose a managed SDH/SONET solution, running Ethernet over SDH/SONET.
D.
You agree with the NOC engineer that the heartbeat interval timers for the cluster must be adjusted to accommodate the 125 ms delay.
I choose D
