What are two reasons a network administrator would use CDP? to verify the type of cable interconnecting two devices to determine the status of network services on a remote device to obtain VLAN information from directly connected switches to verify Layer 2 connectivity between two devices when Layer 3 fails to obtain the IP address of a connected device in order to telnet to the device

A network administrator needs to force a high-performance switch that is located in the MDF to become the root bridge for a redundant path switched network． What can be done to ensure that this switch assumes the role as root bridge? Establish a direct link from the switch to all other switches in the network． Assign the switch a higher MAC address than the other switches in the network have． Configure the switch so that it has a lower priority than other switches in the network． Configure the switch for full-duplex operation and configure the other switches for half-duplex operation． Connect the switch directly to the MDF router, which will force the switch to assume the role of root bridge．

Why will a switch never learn a broadcast address? Broadcasts only use network layer addressing． A broadcast frame is never forwarded by a switch． A broadcast address will never be the source address of a frame． Broadcast addresses use an incorrect format for the switching table． Broadcast frames are never sent to switches．

A router receives information about network 192．168．10．0/24 from multiple sources． What will the router consider the most reliable information about the path to that network? a directly connected interface with an address of 192．168．10．254/24 a static route to network 192．168．10．0/24 a RIP update for network 192．168．10．0/24 an OSPF update for network 192．168．0．0/16 a default route with a next hop address of 192．168．10．1

In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN? during high traffic periods after broken links are re-established when upper-layer protocols require high reliability in an improperly implemented redundant topology when a dual ring topology is in use

Refer to the exhibit． What is the effect of the configuration that is shown? [*] It configures SSH globally for all logins． It tells the router or switch to try to establish an SSh connection first and if that fails to use Telnet． It configures the virtual terminal lines with the password 030752180500． It configures a Cisco network device to use the SSH protocol on incoming communications via the virtual terminal ports． It allows seven failed login attempts before the VTY lines are temporarily shutdown．

Refer to the exhibit． The network administrator requires easy configuration options and minimal routing protocol traffic． What two options provide adequate routing table information for traffic that passes between the two routers and satisfy the requests of the network administrator? [*] a dynamic routing protocol on InternetRouter to advertise all routes to CentralRouter． a dynamic routing protocol on InternetRouter to advertise summarized routes to CentralRouter． a static route on InternetRouter to direct traffic that is destined for 172．16．0．0/16 to CentralRouter． a dynamic routing protocol on CentralRouter to advertise all routes to InternetRouter． a static, default route on CentralRouter that directs traffic to InternetRouter．

Refer to the exhibit． Given the output of the Floor3 switch, what statement describes the operation of this switch? [*] VTP is disabled on this switch． The switch can create, change, and delete VLANs． The switch learns VLAN information but does not save it to NVRAM． The switch can create VLANs locally but will not forward this information to other switches． The switch learns VLAN information and updates the local VLAN data base in NVRAM．

R1 forwards a packet from Host 1 to remote Server 1． Which statement describes the use of a MAC as the frame carrying this packet leaves the s0/0/0 interface of R1? [*] The frame does not have MAC addresses． The source MAC address in the frame is the MAC address of the NIC of Host 1． The source MAC address in the frame is the MAC address of the s0/0/0 interface of R1． The destination MAC address in the frame is the MAC address of the NIC of server 1． The destination MAC address in the frame is the MAC address of the s0/0/0 interface of R2

There are no boot system commands in a router configuration in NVRAM． What is the fallback sequence that the router will use to find an IOS during reload? TFTP server, Flash, NVRAM ROM, NVRAM, TFTP server NVRAM, TFTP server, ROM Flash, TFTP server, ROM Flash, NVRAM, ROM

Refer to the exhibit． When PC1 sends an ARP request for the MAC address of PC2, network performance slows dramatically, and the switches detect an unusually high number of broadcast frames． What is the most likely cause of this? [*] The portfast feature is not enabled on all switch ports． The PCs are in two different VLANs． Spanning Tree Protocol is not running on the switches． PC2 is down and is not able to respond to the request． The VTP versions running on the two switches do not match．

What is the function of the Cisco IOS command ip nat inside source static 10．1．1．5 172．35．16．5? It creates a global address pool for all outside NAT transactions． It establishes a dynamic address pool for an inside static address． It creates dynamic source translations for all inside local PAT transactions． It creates a one-to-one mapping between an inside local address and an inside global address． It maps one inside source address to a range of outside global addresses．

Refer to the exhibit． What is the meaning of the term dynamic as displayed in the output of the show frame-relay map command shown? [*] The Serial0/0 interface is passing traffic． The DLCI 100 was dynamically allocated by the router． The Serial0/0 interface acquired the IP address of 172．16．3．1 from a DHCP server． The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud． The mapping between DLCI 100 and the end station IP address 172．16．3．1 was learned through Inverse ARP．

Which of the following statements are true regarding bridges and switches? (Choose 3．) Switches are primarily software based while bridges are hardware based． Both bridges and switches forward Layer 2 broadcasts． Bridges are frequently faster than switches． Switches have a higher number of ports than most bridges． Bridges define broadcast domains while switches define collision domains．
