Enable SSH version 2 Which command will display a summary of all IPv6-enabled interfaces on a router that includes the IPv6 address and operational status? - ANS Show ipv6 interface brief When verifying routes, what code is used to identify directly connected routes in the routing table? - ANS C Which command will display packet flow counts, collisions, and buffer failures on an interface? - ANS Show interface An IPv6-enabled interface is required to have which type of address? - ANS link-local What character is used to enable the filtering of commands? - ANS pipe ] Which filtering expression will show all output lines starting from the line matching the filtering expression? - ANS begin Which port speed will be autonegotiated between a host with a 1 Gbps NIC connecting to a Cisco Catalyst 2960 switch with a 100 Mbps port? - ANS 100 Mbps Which device separates broadcast domains? - ANS Router Which two special characteristics do LAN switches use to alleviate network congestion? - ANS Fast port speeds Fast internal switching Which statement is true about broadcast and collision domains? - ANS Adding a switch to a network will increase the size of the broadcast domain What is one function of a Layer 2 switch? - ANS determines which interface is used to forward a frame based on the destination MAC address What is the significant difference between a hub and a Layer 2 LAN switch? - ANS A switch creates many smaller collision domains, and a hub increases the size of a single collision domain What will a Cisco LAN switch do if it receives an incoming frame and the destination MAC address is not listed in the MAC address table? - ANS Forward the frame out all ports except the port where the fram is received Which switch characteristic helps alleviate network congestion when a 10 Gbps port is forwarding data to a 1 Gbps port? - ANS Frame buffering Which switching method makes use of the FCS value? - ANS Store-and-forward What does the term "port density" represent for an Ethernet switch? - ANS The numer of available ports Which information does a switch use to keep the MAC address table information current? - ANS The source MAC address and the incoming port Which two statements are true about half-duplex and full-duplex communications? - ANS Full duplex increases the effective bandwidth Full duplex allows both ends to transmit and receive simultaneously Which type of address does a switch use to build the MAC address table? - ANS Source MAC address Which option correctly describes a switching method? - ANS store -and-forward: ensures that the frame is free of physical and data-link errors Which network device can serve as a boundary to divide a Layer 2 broadcast domain? - ANS Router What is the purpose of frame buffers on a switch? - ANS They hold traffic, thus alleviating network congestion. Which network device can be used to eliminate collisions on an Ethernet network? - ANS Switch True or false? DTP is an open standard IEEE protocol that specifies auto negotiation of switch trunk links. - ANS False What is the default switchport mode for Cisco Catalyst switches? - ANS Dynamic auto True or false? Two switchports on a link both configured as dynamic auto will successfully negotiate a trunk. - ANS False Which two DTP modes will form a trunk with an interface that is configured as dynamic auto? - ANS Trunk, Dynamic desirable What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch? - ANS The port becomes inactive In which memory location are the VLAN configurations of normal range VLANs stored on a Catalyst switch? - ANS Flash An administrator is investigating a failure on a trunk link between a Cisco switch and a switch from another vendor. After a few show commands, the administrator notices that the switches are not negotiating a trunk. What is a probable cause for this issue? - ANS Switches form other vendors do not support DTP What is the purpose of the file on a switch? - ANS It holds the vlan database What is the purpose of setting the native VLAN separate from data VLANs? - ANS A separate Vlan should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default? - ANS native VLAN ID A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking?​ - ANS between a switch and a server that has an 902.1Q NIC Between two switches that utilize multiple VLANs What are three primary benefits of using VLANs? - ANS Security Cost Reduction On a Cisco switch, where is extended range VLAN information stored? - ANS running configuration file In which location are the normal range VLANs stored on a Cisco switch by default? - ANS flash-memory Which distinct type of VLAN is used by an administrator to access and configure a switch? - ANS management VLAN For what reason would a network administrator use the show interfaces trunk command on a switch? - ANS to view the native VLAN Where is the file stored on a switch? - ANS flash memory If an organization is changing to include Cisco IP phones in its network, what design feature must be considered to ensure voice quality? - ANS A separate VLAN is needed for voice traffic
