1. Refer to the exhibit. A pre-sales system engineer receives a diagram of
the current network WAN connectivity from a customer. EIGRP is the
routing protocol used on the WAN. Based on the default operation of
EIGRP, which statement is true about the routing table on router R1?
There is a single route to the 192.168.16.0/28 LAN via the use of the T1 connection.
There is a single route to the 192.168.16.0/28 LAN via the use of the DSL
There is a single route to the 192.168.16.0/28 LAN via the use of the Metro Ethernet

A failure of the switch that connects the Cisco Call Manager to the network will cause
the entire IP telephony system to fail.
Using Layer 3 switches to interconnect the data center servers to the IP phones

points of failure at the access layer.
If one of the Layer 3 switches fails, the Cisco Call Manager will be unreachable.
