Answer: _________
Answer Key
1:
D
Solution: An IPv6 address is 128 bits long.
2:
D
Solution: Port Address Translation (PAT) allows a one-to-many approach to network address translation.
3:
A
Solution: Standard and extended access control lists (ACLs) are used to configure security on a router.
4:
B
Solution: The command to back up the configuration on a router is copy running-config startup-config .
5:
D
Solution: Each device has 10 Mbps to the server.
6:
C
Solution: IEEE 802.11B is 2.4GHz, but with a maximum of only 11Mbps. IEEE 802.11G is in the 2.4GHz range, with a top speed of 54Mbps.
7:
A
Solution: 256 - 192 = 64. 64 + 64 = 128. 128 + 64 = 192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129-190.
8:
D
Solution: The command copy flash tftp will prompt you to back up an existing IOS in flash to a TFTP host.
9:
A
Solution: Network Control Protocol is used to help identify the Network layer protocol used in the packet.
10:
C
Solution: The command line vty 0 4 places you in a prompt that will allow you to set or change your Telnet password.
11:
A
Solution: You should have only one root bridge per network.
12:
C
Solution: LCP (Link Control Protocol) is a part of the PPP (Point-to-Point Protocol) suite that provides essential services for the establishment, configuration, and maintenance of the link. LCP is responsible for dynamic addressing, authentication (like PAP or CHAP), and multilink capabilities, which allow multiple physical connections to be bundled together. Other protocols like NCP are used for configuring network layer protocols, but LCP handles these specific tasks. Therefore, LCP is the correct answer.
13:
D
Solution: Stub networks have only one connection to an internetwork. Only default routes can be set on a stub network or network loops may occur.
14:
D
Solution: The clock rate command is two words, and the speed of the line is in bps.
15:
C
Solution: VLANs break up broadcast domains at layer 2.
16:
C
Solution: The primary reason the OSI model was created was so that different networks could inter-operate.
17:
D
Solution: Layer 2 switching creates individual collision domains.
18:
B
Solution: The show interface command shows the line, protocol, DLCI, and LMI information of an interface.
19:
C
Solution: ICMP is the protocol at the Network layer that is used to send echo requests and replies.
20:
D, H
Solution: The copy tftp flash command places a new file in flash memory, which is the default location for the Cisco IOS in Cisco routers.
21:
A
Solution: The command erase startup-config deletes the configuration stored in NVRAM.
22:
B
Solution: VTP is not right because it has nothing to do with trunking except that it sends VLAN information across a trunk link. 802.1Q and ISL are used to configure trunking on a port.
23:
C
Solution: User Datagram Protocol is a connection network service at the Transport layer, and DHCP uses this connectionless service.
24:
C
Solution: The show ip interface command will show you if any outbound or inbound interfaces have an access list set.
25:
B
Solution: Hubs regenerate electrical signals, which are specified at the Physical layer.
26:
B
Solution: The passive command, short for passive-interface, stops regular updates from being sent out an interface. However, the interface can still receive updates.
27:
C
Solution: ICMP is the protocol at the Network layer that is used to send messages back to an originating router.
28:
B
Solution: Every 2 seconds, BPDUs are sent out from all active bridge ports by default.
29:
A
Solution: By default, switches break up collision domains but are one large broadcast domain.
30:
C
Solution: The command line console 0 places you at a prompt where you can then set your console user-mode password.
31:
B
Solution: To see the contents of all access lists, use the show access-lists command.
32:
A
Solution: Class A addressing provides 24 bits for host addressing.
33:
D
Solution: Switches do not propagate VLAN information by default
you must configure the VTP domain. VLAN Trunking Protocol (VTP) is used to propagate VLAN information across a trunk link.
