3 A ping command is issued on workstation A to determine if workstation B can be reached. What events will occur if this command is successful? (Choose two.)

The router will block the ping request message. The router will reply to the echo request with a proxy ping response. Workstation A will send a UDP ping request message to workstation B. Workstation B will send a UDP ping reply message to workstation A. Workstation A will send an ICMP echo request message to workstation B. Workstation B will send an ICMP echo reply message to workstation A.

4 How is spanning-tree path cost determined by default?

total hop count sum of the costs based on bandwidth dynamically determined based on load individual link cost based on latency

5 Which of the following statements describes the operation of routing with EIGRP? (Choose three.)

As new neighbors are discovered, entries are placed in a neighbor table. If the feasible successor has a higher advertised cost than the current successor route, then it becomes the primary route. If hello packets are not received within the hold time, DUAL must recalculate the topology. The reported distance is the distance to a destination as advertised by a neighbor. Routes learned through IGRP are identified as internal routes. EIGRP builds one routing table that contains routes for all configured routed protocols.

6 What are the two basic functions that a router uses to relay packets?

filtering and switching path determination and filtering path determination and switching traffic analysis and filtering

7 A partial configuration of a Catalyst 1900 switch is shown in the graphic. Why do the following commands fail to delete VLAN1 and VLAN2? (Choose two.)

no vlan 1 no vlan 2

VLAN 1 is not configured on the switch. VLAN 1 is the default VLAN and cannot be removed. The network administrator is using the wrong command. The switch is configured in VTP client mode. Ports are still assigned to VLAN 1 and VLAN 2 and the VLANs cannot be deleted until those assignments are removed.

16 Host A in the graphic has received its DHCP configuration from R1. Host A is unable to reach the Internet. What could cause this problem?

The DNS server is not on the same LAN as Host A. The ip helper-address command must be configured on the Ethernet interface. Host A did not receive the correct gateway address. The DHCP service has not been enabled on interface e0. The router IP address has been excluded from the DHCP pool. The subnet mask in the network command is incorrect.

20 How is RIP configured on a router?

RIP is configured globally and then assigned an IP address and subnet mask. RIP is configured globally and then applied to each interface that will participate in the RIP routing process. RIP is configured individually on each interface that will participate in the RIP routing process. RIP is enabled globally and then networks are associated with the RIP routing process.

21 What are the advantages of OSPF in comparison with RIP v2? (Choose two.)

OSPF provides support for Classless Interdomain Routing but RIP v2 does not. OSPF may result in faster convergence, due to triggered updates. OSPF's built-in features make it easy to design, implement, and troubleshoot. OSPF routers build a complete view of the network, reducing the potential for routing loops. OSPF sends periodic link state advertisements to keep the link active. OSPF routers have lower memory and processor requirements.

22 Which protocol of the TCP/IP model internet layer provides connectionless, best-effort-delivery of datagrams?


23 Which of the following is an alternative to a dedicated WAN link?

X.25 ISDN T1 DS3

29 Which statements reflect the process of common LAN protocols accessing the media? (Choose three.)

Ethernet is a non-deterministic protocol that allows the first node that accesses the medium to transmit its data. Token Ring is a deterministic protocol that allows only one node within the ring a turn to transmit data before passing control to the next node. Token Ring is a non-deterministic protocol that uses a first-come, first-serve approach for nodes to seize the token and transmit data. FDDI networks use a deterministic approach to assure that each node has fair access to the medium. Ethernet and Token Ring networks avoid collisions by allowing only one node to transmit at a time. Ethernet is a deterministic protocol that uses CSMA/CD to assure that each node takes turns to access the medium.

30 What is the purpose of DLCIs in Frame Relay?

They determine the Frame Relay encapsulation type. They identify the logical circuit between a local router and a Frame Relay WAN switch. They represent the keepalives used to maintain the PVC in an active state. They represent the physical address of the router attached to a Frame Relay network.

31 An administrator has an older 1900 switch located on the edge of the network. What can the network administrator do to ensure that it does not become the root bridge of the spanning-tree network?

decrease the BPDU hello timer update on the 1900 assign the highest IP address to the switch that should be the root assign the lowest IP address to new root bridge assign the lowest priority to the switch that should be the root assign the highest priority to the new root bridge decrease the BID on the 1900 switch

32 What command is used to verify that a Frame Relay link is up and operational?

Router# show line Router# show version Router# show interface Router# show frame-relay Router# show frame-relay status

33 Which of the following are true regarding bridges and switches? (Choose two.)

Bridges are faster than switches because they have fewer ports. A switch is a multiport bridge. Bridges and switches learn MAC addresses by examining the source MAC address of each frame received. A bridge will forward a broadcast but a switch will not. Bridges and switches increase the size of a collision domain.

34 Which of the following does CHAP authentication use to increase security on a PPP link? (Choose three.)

38 The network in the graphic is using EIGRP with the metrics shown. Router A has a route to network through Router C, with a feasible distance of three. What will happen if the direct link between A and C becomes unavailable? (Choose two.)

DUAL will immediately promote the feasible successor route through Router B to successor route status. The route to Network C on Router A will be placed in Active status. The route to Network C on Router A will be placed in Passive status. Router A will send query packets to all neighbor routers. Router A will mark the link as down until regularly scheduled update packets are received.

44 Which statements are true regarding OSPF DR and BDR elections? (Choose three.)

The command ip ospf prioritypriority number is used to set the priority value that determines the DR. The default priority value for a router connected to a multiaccess network is 0. The router with the highest MAC address is elected as the DR when the default priority values are used. The loopback interface must be configured on the DR. The BDR is selected from remaining routers and uses the same criteria applied in the DR election. There are no DRs or BDRs on point-to-point links.

Frame Relay and ISDN Frame Relay and X.25 ISDN and X.25 ISDN only

46 Which statement describes the store and forward transmission mode of an Ethernet switch?

It is also referred to as a hybrid mode or as error sensing mode. It requires the switch to read the first 64 bytes of an Ethernet frame and then begins to forward the data. It decreases the latency of the transmission but has very little error detection. It increases latency with large frames, but error detection is high.

52 In an effort to minimize traffic, an administrator decided to keep web traffic from causing the ISDN link to come up by denying WWW traffic to the remote server. Two minutes after making changes to the configuration as shown in the graphic, the administrator notices that web traffic is still passing over the link. What is the most likely cause of the problem?

The dialer-group has not been applied to outbound traffic. The access-list is incorrectly configured. Broadcasts are creating "interesting" traffic and keeping the link active. The command ip access-group 128 out is missing from the bri0/0 interface.

He didn't say what he'd pay so why should anyone help him?

Also he posted material that breaches Cisco's user agreement, and how is he going to share his discount with us anyway?

He can do it like the rest of us did - by actually learning and knowing that stuff.

Besides he's delusional, who'd employ someone who obtained a certification by false pretences?

I don't think that's a good idea. What if I have to connect a network I've built to a network you build not knowing the answers to these questions?

I'll be weeks untangling it.
