Answer: Option B

Solution:

It provides fallback for IE8.

ATM switches use the VPI/VCI fields of the cell header:

To identify the QOS parameters specified in the traffic contract between the ATM end station and the
network ✘ To determine if the cell should be discarded in preference to others that have not exceeded their trafficenvelope ✘ To identify the next intermediate destination to which the cell should be passed ✘ To determine if the header contains a checksum error and should be discarded ✔ To determine if the cell contains user data or control data ✔

According to the diagram, a PPPoE session is initiated by the user from the PC using the username johndoe@isp1.com. This PPPoE session ultimately terminates on the ISP router, using domain based tunneling on 6400. What is the correct sequence of events which occur during user authentication?

The 6400 will query the PC to get the domain name. The 6400 will issue a PPP authentication challenge to
which the PC will respond using the username johndoe@isp1.com. Once the tunnel is established, the ISP
router will issue a challenge to the user and will authenticate the response. ✘ The 6400 will issue a PPP authentication challenge to which the PC will respond using the usernamejohndoe@isp1.com. The 6400 will authenticate the user. It will also use the domain name to find out the
tunnel endpoint. The tunnel is established and user traffic will now be allowed to flow without any further
authentication. ✘ The 6400 will issue a PPP authentication challenge to which the PC will respond using the usernamejohndoe@isp1.com. The 6400 will use the domain name isp1.com to find out the tunnel endpoint. It will
forward the authentication information to the ISP router which will authenticate the user. ✘ The 6400 will use the PVC number to decide the tunnel endpoint. Once the tunnel is established, the ISProuter will issue a challenge to the user and will authenticate the response. ✔ None of the above ✔

Virtual path identifier (VPI) and virtual channel identifier (VCI) values on the NRP-2 must share ___bits. By default, VPI values are limited to ___ bits (0-15), and VCI values are limited to ___ bits (0-1023). A Network
Administrator can change the VPI and VCI ranges, but together the VPI and VCI values cannot exceed ___ bits. Which numbers below, correctly fill in the blanks?

16, 6, 10, 16 ✘ 18, 4, 12, 16 ✘ 18, 4, 8, 12 ✘ 14, 4, 10, 14 ✔ 14, 5, 9, 14 ✔

What statement regarding Service Selection Gateway is INCORRECT?

For Proxy Service, the SSG will proxy the Access-Request to the remote AAA server. Upon receiving an
Access-Accept from the remote RADIUS server, the NRP-SSG responds to the subscriber with the Access-
Accept. ✘ Transparent passthrough service allows unauthenticated subscriber traffic to be routed through the NRP-SSG in either direction. ✘ For Proxy service, the SSG can perform NAT between the address assigned by the remote server and thesubscriber's real IP address. ✘ For non-PPP users, such as those in bridged networks, if the user disconnects from a service withoutlogging off, the connection will remain open and the user can reaccess the service without going through
logon procedure as long as the session has not timed out. ✔ The PPP Termination Aggregation (PTA) service can be used only in dialup environments and with PPPoEin DSL environments. It cannot be used with PPPoA. ✔

A Network Administrator is unable to configure a PVC with the value of 8/49. He looks at the running config and notices the following entry for the interface he is working with. What is the likely cause of the problem?interface
ATM0/0/0no ip addressatm vc-per-vp 2048no atm ilmi-keepalive

ILMI has timed out without keepalives. ✘ The config is fine; the NSP must be the source of the problem. ✘ An IP address is required to turn up PVCs. ✘ The interface is shutdown. ✔ Too many bits have been assigned to the VCs reducing the possible values of the VP. ✔

10.

What is the purpose of the following command? virtual-template {template-number\}pre-clone {number\}

Used in a PPPoA environment, it will improve the memory utilization by decreasing the number of dynamic

interfaces created. ✘ Used in either a PPPoA or PPPoE environment, it will decrease the time needed to boot the NRP bycreating needed access interfaces before they are needed. ✘ Used in a PPPoE environment, it will increase the time needed for a user to connect to the NRP byallocating access interfaces at boot time. ✘ Used in a PPPoE environment, it will pre-create a defined number of dynamic access interfaces to reducethe load on the NRP during times of peak user logins. ✔ Used in either a PPPoA or PPPoE environment, it will increase the initial load on the NRP by pre-creating adefined number of dynamic access interfaces. ✔
