When designing a prototype network for a new server farm, a network designer chooses to use redundant links to connect to the rest of the network. Which business goal will be addressed by choice? security scalability availability manageability

Refer to the exhibit. An administrator installs a WIC-2T module into a Cisco 1841 router. Attemp

configure the S0/0/0 interface are unsuccessful. As a first step in troubleshooting the failure, the administrator issues the show version command. What is a possible reason for the failure? 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 configuration register is the wrong value for adding new modules. 4 Which two processes allow a smooth transition from IPv4 to IPv6? (Choose two.) IPSec tunneling dual stack authentication anycast addressing header simplification

5

Which feature relies on prioritization of network traffic and is used to ensure successful delivery real-time services? security reliability redundancy quality of service Which two values represent valid IPv6 addresses? (Choose two.) ::::1 FF01::1 0:0:0:0:0:0:0:1 2001:DB8::47::2A4 2031:0000:04AC:3400:FFE3:0

The main office of a NetworkingCompany customer currently connects to three branch offices v three separate point-to-point T1 circuits. The customer network uses RIPv2 as the routing proto within both the LAN and the WAN. The account manager proposes a change to a Frame Relay network because the costs are lower. A single local loop connection can be installed at the mai with three separate PVCs to connect the branch offices. How can the main office edge router b configured to enable the customer to continue to use RIP as the WAN routing protocol? Enable Inverse ARP on the serial interface in order to learn the routes to the IP addresses o remote routers. To prevent the Frame Relay network from causing a routing loop, disable split horizon on th serial interface. Create three separate point-to-point subinterfaces on the serial interface and assign a differ subnet IP address to each one. Configure the serial interface with a single interface DLCI number and create frame-relay mapstatements for each remote site address.

Which statement best describes the VPN feature called split tunneling? 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 tunn 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 high bandwidth tunnel, while all other user traffic travels on the lower bandwidth tunnel.

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. The R1 to R3 and R1 to R2 WAN links have IP addresses that overlap. The WAN IP address that connects R1 to R2 overlaps with the R3 LAN IP addresses. 10

Refer to the exhibit. All router interfaces are up and RIP version 2 is configured as the routing p The users in networks 172.16.8.0 /24 and 172.16.9.0/24 are not able to reach users in the 172.16.16.0/24 network. The network administrator examines the routing tables and finds that e though all directly connected networks have been entered in the RIP configuration, not all route present. What is the most likely cause of this problem? Autosummarization is enabled on all routers. The split-horizon rule is disabled on all routers. RIP version 2 does not support classless routing. RIP version 1 should have been used instead of version 2. The 10.10.4.0 networks should be replaced with 192.168.4.0 networks. Showing 1 of 6 Next> Page:
