NO.1 A switch receives a frame on one of its ports. There is no entry in the MAC address table for the
destination MAC address. What will the switch do with the frame?
A. drop the frame
B. forward it out of all ports except the one that received it
C. forward it out of all ports
D. store it until it learns the correct port
Answer: B
NO.2 Refer to the exhibit.
The junior network support staff provided the diagram as a recommended configuration for the first
phase of a four-phase network expansion project. The entire network expansion will have over 1000
users on 14 network segments and has been allocated this IP address space.
192.168.1.1 through 192.168.5.255
192.168.100.1 through 192.168.100.255
What are three problems with this design? (Choose three.)
A. The AREA 1 IP address space is inadequate for the number of users.
B. The AREA 3 IP address space is inadequate for the number of users.
C. AREA 2 could use a mask of /25 to conserve IP address space.
D. The network address space that is provided requires a single network-wide mask.
E. The router-to-router connection is wasting address space.
F. The broadcast domain in AREA 1 is too large for IP to function.
Answer: A,C,E
Explanation:
The given IP addresses of areas 1 and 3 along with network masks of 24 cannot
accommodate 500 users so are inadequate, while the area 2 is having over capacity so its
network mask can be reduced to 25 to accommodate the only 60 users it has.
NO.3 What is the purpose of assigning an IP address to a switch?
A. provides local hosts with a default gateway address
B. allows remote management of the switch
C. allows the switch to respond to ARP requests between two hosts
D. ensures that hosts on the same LAN can communicate with each other
Answer: B
NO.4 Which statements describe the routing protocol OSPF? (Choose three.)
A. It supports VLSM.
B. It is used to route between autonomous systems.
C. It confines network instability to one area of the network.
D. It increases routing overhead on the network.
E. It allows extensive control of routing updates.
F. It is simpler to configure than RIP v2.
Answer: A,C,E
NO.5 Refer to the output of the corporate router routing table shown in the graphic.
The corporate router receives an IP packet with a source IP address of 192.168.214.20 and a
destination address of 192.168.22.3.
What will the router do with this packet?
A. It will encapsulate the packet as Frame Relay and forward it out interface Serial 0/0.117.
B. It will discard the packet and send an ICMP Destination Unreachable message out interface
FastEthernet 0/0.
C. It will forward the packet out interface Serial 0/1 and send an ICMP Echo Reply message out
interface serial 0/0.102.
D. It will change the IP packet to an ARP frame and forward it out FastEthernet 0/0.
Answer: B
NO.6 Refer to the exhibit.
If the router Cisco returns the given output and has not had its router ID set manually, what value will
OSPF use as its router ID?
A. 192.168.1.1
B. 172.16.1.1
C. 1.1.1.1
D. 2.2.2.2
Answer: D
NO.7 Which IOS command is used to initiate a login into a VTY port on a remote router?
A. router# login
B. router# telnet
C. router# trace
D. router# ping
E. router(config)# line vty 0 5
F. router(config-line)# login
Answer: B
Explanation:
Explanation/Reference:
VTY ports are telnet ports hence command B will initiate login to the telnet port.
NO.8 Which statements accurately describe CDP? (Choose three.)
A. CDP is an IEEE standard protocol.
B. CDP is a Cisco proprietary protocol.
C. CDP is a datalink layer protocol.
D. CDP is a network layer protocol.
E. CDP can discover directly connected neighboring Cisco devices.
F. CDP can discover Cisco devices that are not directly connected.
Answer: B,C,E
Explanation:
CDP (Cisco Discovery Protocol) is a proprietary protocol designed by Cisco to help administrators
collect information about both locally attached and remote devices.
By using CDP, you can gather hardware and protocol information about neighbor devices containing
useful info for troubleshooting and documenting the network.
