43	Top of Form Refer to the exhibit. A networking company designer is reviewing a diagram of a customer network. What are the two problems that need to be resolved in the topology that is shown? (Choose two.) The firewall router and ISP connection represent a single point of failure. If one of the Layer 3 switches fails, the Cisco Call Manager will be unreachable. A power supply failure of the server block switch will cause the entire IP telephony system to fail. Using Layer 3 switches to interconnect the server block servers to the IP phones introduces too much delay. The IP phones need to be redundantly connected to the switches to prevent single points of failure at the access layer. Bottom of Form
44	Top of Form Refer to the exhibit. What problem is associated with the the addressing scheme of the network? The WAN links need IP addresses from a different major network. The R1 LAN is incorrect because subnet zero cannot be used with VLSM. The WAN link IP address that connects R1 to R3 has an incorrect mask.
