An IP SLA is configured to use the backup default route when the primary is down, but it is not working as desired. Which command fixes the issue?

1. A. R1(config)# ip route 0.0.0.0.0.0.0.0.2.2.2.2 10 track 1
2. B. R1(config)# ip route 0.0.0.0.0.0.0.0.2.2.2.2
3. C. R1(config)#ip sla track 1
4. D. R1(config)# ip route 0.0.0.0.0.0.0.0.1.1.1.1 track 1

Correct Answer: D
Reference:
Note: By default Static Router AD value-1 hence ip route 0.0.0.0. 0.0.0.0. 1.1.1.1 track 1 means AD-1 which must be less than of back up route AD.
Define the backup route to use when the tracked object is unavailable. !--- The administrative distance of the backup route must be greater than !--- the administrative distance of the tracked route.!--- If the primary gateway is unreachable, that route is removed!--- and the backup route is installed in the routing table!--- instead of the tracked route.

What is the minimum time gap required by the local system before putting a BFD control packet on the wire?

1. A. Detect Mult
2. B. Required Min Echo RX Interval
3. C. Desired Min TX Interval
4. D. Required Min RX Interval

Correct Answer: C
Desired Min TX Interval: This is the minimum interval, in microseconds, that the local system would like to use when transmitting BFD Control packets, less any jitterapplied. The value zero is reserved.
Required Min Echo RX Interval: This is the minimum interval, in microseconds, between received BFD Echo packets that this system is capable of supporting, less anyjitter applied by the sender. If this value is zero, the transmitting system does not support the receipt of BFD Echo packets.
