Review for CCNA Discovery 4.
There is a single route to the 192.168.24.0/24 LAN using the T1 connection.
There is a single route to the 192.168.24.0/24 LAN using the DSL connection.
There is a single route to the 192.168.24.0/24 LAN using the Metro Ethernet connection.
EIGRP installs all three routes to the 192.168.24.0/24 LAN and load balances the traffic

The remote router updates the Frame Relay map table with DLCI 35 to reach the 10.1.10.0 network.
Inverse ARP is used to add an entry for the 10.1.10.1 into the Frame Relay map table via the use of DLCI 5.
DLCI 35 replaces the MAC address in the ARP table for entry 10.1.10.1.
A Layer 2 address is statically mapped to a Layer 3 address.
Router BRT uses DLCI 35 to forward data to 10.1.10.1.

It creates separate pathways for different VLANs.
It creates two tunnels, one for user traffic and one for management traffic such as CDP and SNMP.
It allows user traffic that is destined for the corporate network to travel across the VPN tunnel, while traffic destined for the Internet travels through the local LAN of the VPN client.
It allows separate tunnels so that high priority traffic, such as voice and video, uses the higher bandwidth tunnel, while all other user traffic travels on the lower bandwidth tunnel.

Redundant links are not blocked.
Routing tables converge more quickly.
Spanning Tree convergence times are reduced.
Assign to each server a static internal IP address that is mapped statically to a public IP address.
Place all servers in their own class C private subnet.
Provide a private address to each server using DHCP.
Assign addresses from a pool of public Class B addresses using DHCP.
The router needs a routing protocol configured.
The router needs additional Fast Ethernet interfaces installed.
The subinterfaces of the router should have IP addresses applied.
All the subinterfaces of the router should be configured in the same VLAN.
The subinterfaces must be the same value as the VLAN ID that they are routing for.
The router sends the traffic out Serial 0/0/0.
The router sends the traffic out all interfaces other than the one it came in on.
The router places the packets into a queue until a better route is discovered via RIP.
The router sends a request to neighbouring routers for paths to the 172.18.10.0 network.
The WIC was not physically installed properly.
The WIC was installed into slot 1 instead of slot 0.
The interface type and number are invalid on an 1841.

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.

Inform the customer that the project budget must be increased.
Inform the customer that the project cannot be completed given the unreasonable budget constraints.
Communicate any risks that are associated with the equipment substitution and obtain customer approval to proceed.
Because the customer is probably aware that the budget limitations will require lower cost, less capable equipment, the account manager should do nothing.

Create three separate point-to-point subinterfaces on the serial interface and assign a different subnet IP address to each one.
Configure the serial interface with a single i nterface DLCI number and create frame -relay map statements for each remote site address.
The WAN link that connects R1 to R3 has an incorrect mask.
The WAN links need IP addresses from a different major network.
The WAN link that connects R1 to R2 overlaps with the R3 LAN.
The IP addressing in R1 LAN is incorrect because subnet zero cannot be used with VLSM.
