A collection of interconnected switches forms a _______________________.
  • Broadcast domain Correct
  • Common domain
  • Collision domain
  • Shared domain
A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0. However, when the administrator issues the command show ip route, the routing table does not show the directly connected network. What is the possible cause of the problem?
  • The configuration needs to be saved first
  • The interface fa0/0 has not been activated Correct
  • The subnet mask is incorrect for the IPv4 address
  • No packets with a destination network of 1721610 have been sent to R1
A network administrator has examined the routing table of a router and noted that the entry for the destination network 172.16.4.0/24 begins with the letter D. What does this letter signify?
  • The route source was learned dynamically Correct
  • The route to network 1721640/24 is directly connected
  • The route to this network is configured statically on the router
  • That is the direct route for packets to that network
A network administrator of Stark Industries has examined the routing table of a router and noted that the entry for the destination network 172.16.4.0/24 begins with the letter D. What does this letter signify?
  • The route to network 1721640/24 is directly connected
  • The route source was learned dynamically Correct
  • The route to this network is configured statically on the router
  • That is the direct route for packets to that network
A network engineer for a semiconductor company wants to use the primary ISP connection for all external connectivity. Refer at the diagram below. The backup ISP connection is used only if the primary ISP connection fails. Which set of commands would accomplish this goal?
  • ip route 19813321924 255255255252ip route 6410021080 255255255252
  • ip route 0000 0000 s0/0/0ip route 0000 0000 s0/1/0
  • ip route 19813321924 255255255252ip route 6410021080 255255255252 10
  • ip route 0000 0000 s0/0/0ip route 0000 0000 s0/1/0 10 Correct
A router has two FastEthernet interfaces and needs to connect to four vlans in the local network. How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance?
  • Use a hub to connect the four vlans with a FastEthernet interface on router
  • Add two more FastEthernet interfaces
  • Add a second router to handle the vlan traffic
  • Implement a router-on-a-stick configuration Correct
A switch forwarding method that begins the forwarding process after the destination MAC address of an incoming frame and the egress port has been determined.
  • Automatic-forward switching
  • Rapid Frame forwarding
  • Store-and-forward switching
  • Cut-through switch method Correct
A switch forwarding method that makes a forwarding decision on a frame after it has received the entire frame and then checked the frame for errors.
  • Rapid Frame forwarding
  • Cut-through switch method
  • Store-and-forward switching Correct
  • Automatic-forward switching
A switch is configured with all ports assigned to vlan 2 with full duplex FastEthernet to segment existing departmental traffic. What is the effect of adding switch ports to a new VLAN on the switch?
  • More bandwidth will be required than was needed previously
  • More collision domains will be created
  • IP address utilization will be more efficient
  • An additional broadcast domain will be created Correct
A type of VLAN that is configured to carry user-generated traffic.
  • Data VLAN Correct
  • Native VLAN
  • Default VLAN
  • Management VLAN
After typing show interface vlan 99 at the switch, What is the bandwidth on this interface?
  • BW 1000000 mbps
  • BW 1000000 kbit Correct
  • BW 1000000 Mbit
  • BW 1000000 bits
All hosts in the networks have been operational for several hours when the DHCP server goes down. What happens to the hosts that have obtained service from the DHCP server?
  • The hosts will be able to communicate with hosts outsides their own network
  • The hosts will not be able to communicate with any otherhosts
  • The hosts will continue to communicate normally for a period of time Correct
  • The hosts will only be able to communicate with otherhosts by IP address not by hostname
Configurations are stored within a VLAN database file, called
  • vlancfg
  • vlandat Correct
  • cisco_vlanini
  • cisco_vlandat
