Top of FormA company has help desk staff that is not highly trained in VPNs. What two features or technologies must the network designer identify as training needs in order for the help desk to support secure remote access for teleworkers? (Choose two.)

QoS operation

VLAN configuration

tunneling protocols

IPv6 and IPv4 dual stack

encryption algorithms

Frame Relay configuration

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 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.

Refer to the exhibit. What does the TOR router do with traffic that is destined for a web server with an IP address of 172.18.10.24?

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 neighboring routers for paths to the 172.18.10.0 network

A user in a large office calls technical support to complain that a PC has suddenly lost connectivity to the network. The technician asks the caller to talk to nearby users to see if other machines are affected. The caller reports that several immediate neighbors in the same department have a similar problem and that they cannot ping each other. Those who are seated in other departments have connectivity. What should the technician check as the first step in troubleshooting the issue?

the power outlet to the PC that is used by the caller. the trunks between switches in the wiring closet.

the status of the departmental workgroup switch in the wiring closet. the cable that connects

the PC of the caller to the network jack. the cable connection between a PC and a network outlet that is used by a neighbor.

The main office of a NetworkingCompany customer currently connects to three branch offices via three separate point-to-point T1 circuits. The customer network uses RIPv2 as the routing protocol 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 main office with three separate

PVCs to connect the branch offices. How can the main office edge router be 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 of the remote routers.

To prevent the Frame Relay network from causing a routing loop, disable split horizon on the serial interface

. 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 interface DLCI number and create frame-relay map statements for each remote site address.

sites. The distance from each site should not make the solution more expensive. Which WAN technology meets the requirements of the company?

DSL cable

Frame Relay T1 leased line

Refer to the exhibit. A pre-sales system engineer receives a diagram of the current WAN 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 192.168.16.0/24 LAN using the T1 connection. There is a single

route to the 192.168.16.0/24 LAN using the DSL connection. There is a single route to the

192.168.16.0/24 LAN using the Metro Ethernet connection. EIGRP installs all three routes to the 192.168.16.0/24 LAN and load balances the traffic.

Which feature of network design and configuration would be considered a weakness?

Choosing a flat network model. Choosing to implement an IPS instead of IDS. Choosing to

disable Telnet and allow only SSH connections for remote access to the core routers. Choosing not to broadcast the SSID for wireless access points.

Refer to the exhibit. What can the field engineer conclude about the EIGRP authentication between Router1 and Router2?

Authentication will fail because only one key is configured. Authentication will succeed and

EIGRP updates can be exchanged. Authentication will fail because the key chain names do not

match. Authentication will fail because the key chain names must match the router names.

Refer to the exhibit. A networking engineer is characterizing an existing network for a new customer. The engineer issues a show running-config command on the R1 router to gather configuration information. What is the engineer able to determine as a result of viewing the output of this command?
