65 What are the two types of access lists that can be configured on a Cisco router?
A. Standard
B. Extended
C. Filtering
D. Packet
Ans: A & B


The access lists are standard and extended. Standard access lists for IP check the source
address of packets that could be routed. Extended access lists can check the source and
destination packet plus check for specific protocols, port numbers, etc.
66 When using access lists, what does a Cisco router check first?
A. To see if the packet is routable or bridgeable
B. The destination address
C. The source address
D. The packet contents
Ans A


The first thing checked is to see if the packet is routable or bridgeable. If it is not, the packet will be dropped.

67 How many access lists are allowed per interface?
A. One per port, per protocol
B. Two per port, per protocol
C. Unlimited
D. Router interface +1 per port.
Ans: A
Only one access list is allowed per interface. An access list must have conditions that test true for
all packets that use the access list.

68 What do the following commands accomplish?
access-list 1 deny 172.16.4.0 0.0.0.255
access-list 1 permit any interface ethernet 0
IP access-group 1 out
A. This will block traffic from subnet 172.16.4.0 and allow all other traffic.
B. This will allow traffic from subnet 172.16.4.0 and block all other traffic.
C. All traffic is allowed.
D. All traffic is blocked.
Ans: A
This will block traffic from subnet 172.16.4.0 and allow all other traffic. The first statement
“access-list 1 deny 172.16.4.0 0.0.0.255” will deny access to the subnet 172.16.4.0.

69 What do the following statements in an extended access list accomplish?
access-list 101 deny TCP 172.16.4.0 0.0.0.255 172.16.3.0 0.0.0.255 eq 21
access-list 101 deny TCP 172.16.4.0 0.0.0.255 172.16.3.0 0.0.0.255 eq 20
access-list 101 permit TCP 172.16.4.0 0.0.0.255 0.0.0.0 255.255.255.255
A. This will block ftp traffic.
B. This will block http traffic.
C. This will permit ftp traffic.
D. This will permit tftp traffic.
Ans: A
This will block ftp traffic since ftp uses ports 20 and 21.

70 Access lists are numbered. Which of the following ranges could be used for an IP
access list?
A. 600 – 699
B. 100 – 199
C. 1 – 99
D. 800 – 899
E. 1000 – 1099
Answer: B & C


AppleTalk access lists use numbers in the 600 – 699 range. IP uses 1 – 99 for standard access
lists or 100-199 for extended access lists. IPX uses 800 – 899 or 900 – 999 for extended access
lists. IPX SAP filters use 1000 – 1099.

71 Cisco routers use wildcard masking to identify how to check or ignore corresponding IP address bits. What does setting a wildcard mask bit to 0 cause the router to do?
A. It tells the router to check the corresponding bit value.
B. It tells the router to ignore the corresponding bit value.
C. It tells the router to check its alternate routing list.
D. It tells the router to use its primary routing list.
Ans A


It tells the router to check the corresponding bit value.

72 You are a system administrator and you want to deny access to a group of computers
with addresses 172.30.16.0 to 172.30.31.0. Which wildcard mask would you use?
A. 0.0.15.255
B. 0.0.255.255
C. 0.0.31.255
D. 0.0.127.255
E. 0.0.255.255
Ans: A
0.0.15.255 will check the last 13 bits of an address so that computers 172.30.16.0 to 172.30.31.0
will be denied access. 0.0.31.255 would check the last 6 binary digits and deny access to
addresses 172.30.32.0 to 172.30.63.0. 0.0.127.255 would check the last 7 binary digits and deny
access to addresses 172.30.64.0 to 172.30.127.0. 0.0.255.255 would deny 172.30.0.0 to
172.30.254.0. If you write decimal 15 in binary, you have 0001111, the 1’s tell the router to ignore
address with these bits set; 0’s tell the router to check the bits. The third octet for 172.30.16.0 is
00010000. The third octet for 172.30.31.0 would be 00011111. So, traffic from these addresses
would be denied.

73 In order to limit the quantity of numbers that a system administrator has to enter, Cisco
can use which abbreviation to indicate 0.0.0.0?
A. host
B. any
C. all
D. include
Ans: A
Cisco uses host to specify 0.0.0.0. This tells the router to check all. Cisco uses any to specify
255.255.255.255. This tells the router to ignore all and permit any address to use an access list
test.

74 What do the following commands accomplish?
access-list 1 permit 172.16.0.0 0.0.255.255
interface ethernet 0
IP access-group 1 out
interface ethernet 1
IP access-group 1 out
A. Only traffic from the source network 172.16.0.0 will be blocked.
B. Only traffic from the source network 172.16.0.0 will be forwarded. Non-172.16.0.0 network
traffic is blocked.
C. Non-172.16.0.0 traffic will be forwarded.
D. All traffic will be forwarded.
Ans: B
Only traffic from the source network 172.16.0.0 will be forwarded. Non-172.16.0.0 network traffic
is blocked. The wildcard mask 0.0.255.255 tells the router to check the first 2 octets and to ignore
the last 2 octets. 75 When using access lists, it is important where those access lists are placed. Which
statement best describes access list placement?
A. Put standard access lists as near the destination as possible. Put extended access lists as
close to the source as possible.
B. Put extended access lists as near the destination as possible. Put standard access lists as
close to the source as possible.
C. It isn’t import where access lists are placed since the router will read and cache the whole list.
D. Put access lists as close to corporate headquarters as possible.
Ans A
Put standard access lists as near the destination as possible. Put extended access lists as close
to the source as possible. Standard access lists don’t specify the destination address.

76 As the system administrator, you enter the following commands at the command
prompt:
ipx routing

int e0
ipx network 4d
ipx access-group 800 out
int e1
ipx network 2b
int e2
ipx network 3c
What did these command accomplish?
A. Traffic from network 4c destined for network 4d will be forwarded out Ethernet0.
B. Traffic from network 3c destined for network 4d will be forwarded out Ethernet0.
C. Traffic from network 2b destined for network 4d will be forwarded out Ethernet0.
D. Traffic from network 4d destined for network 2d will be forwarded out Ethernet0.
Ans C
Traffic from network 2b destined for network 4d will be forwarded out Ethernet0. The other
interfaces E1 and E2 are not subject to the access list since they lack the access group statement
to link them to access list 800.

78 The following commands were entered at the command prompt of a Cisco router. What
do they accomplish?
access-list 1000 deny 9e.1234.5678.1212 4
access-list 1000 permit -1
interface ethernet 0
ipx network 9e
interface ethernet 1
ipx network 4a
interface serial 0
ipx network 1
ipx output-sap-filter 1000

80 Which service uses telephone control messages and signals between the transfer
points along the way to the called destination?
A. Signaling System 7 (SS7)
B. Time-division Multiplexing (TDM)
C. X.25
D. Frame relay
Ans: A
Signaling System 7 (SS7) uses telephone control messages and signals between the transfer
points along the way to the called destination. Time-division Multiplexing (TDM) has information
from multiple sources and allocates bandwidth on a single media. Circuit switching uses signaling
to determine the call route, which is a dedicated path between the sender and the receiver. Basic
telephone service and Integrated Services Digital Network (ISDN) use TDM circuits. X.25 and
Frame Relay services have information contained in packets or frames to share non-dedicated
bandwidth. X.25 avoids delays for call setup. Frame Relay uses permanent virtual circuits
(PVCs).

acceptable to the WAN service’s facility.

83 What is the juncture at which the CPE ends and the local loop portion of the service
begins? A. Demarc
B. CO
C. Local loop
D. Last-mile
Ans A
The demarcation or demarc is the juncture at which the CPE ends and the local loop portion of
the service begins. The CO (Central Office) is the nearest point of presence for the provider’s
WAN service. The local loop or “last-mile” is the cabling that extends from the demarc into the
WAN service provider’s central office.

configuration follows: ipx ethernet 0.1 ipx encapsulation novell-ether ipx network 9e
interface ethernet 0.2 ipx encapsulation sap ipx network 6c
By default, Cisco routers forward GNS SAPs to remote networks.
• A. False
• B. True
Ans A
GNS is Novell’s protocol to Get Nearest Server. If there is a server on the local network,
that server will respond. If there isn’t, the Cisco router has to be configured to forward the
GNS SAP.
9 To prevent Service Advertisements (SAPs) from flooding a network, Cisco routers
do not forward them. How are services advertised to other networks?
• A. Each router builds its own SAP table and forwards that every 60 seconds.
• B. Each router assigns a service number and broadcasts that.
• C. SAPs aren’t necessary with Cisco routers. • D. Cisco routers filter out all SAPs.
Ans: A
Cisco routers build SAP tables and forward the table every 60 seconds. All SAPs can’t be
filtered even with 4.x since NDS and time synchronization uses SAPs.

• C. 60 • D. 90
Ans: A
Novell’s RIP updates routing tables every 60 seconds, Apple’s RTMP is every 10
seconds, routers ARP every 60 seconds, DECnet hosts and IGRP signal every 15
seconds, and Banyan VINES signals every 90 seconds.
29 An autonomous system can only exist if all routers in that system meet which
criteria?
• A. interconnected
• B. run the same routing protocol
• C. assigned same autonomous system number
• D. run IGRP only
• E. run RIP only
Ans A,B &C
An autonomous system is a set of routers and networks under the same administration.
Each router must be interconnected, run the same routing protocol, and assigned the same
autonomous system number. The network Information Center (NIC) assigns a unique
autonomous system number to enterprises.
30 A default route is analogous to a _________.
• A. default gateway
• B. static route
• C. dynamic route
• D. one-way route
Ans: A
A default route is analogous to a default gateway. It is used to reduce the length of
routing tables and to provide complete routing capabilities when a router might not know
the routes to all other networks.

31 Routers can learn about destinations through static routes, default, or dynamic
routing. By default, a router will use information derived from __________.
• A. IGRP • B. RIP
• C. IP
• D. TCP
Ans A
The quality of information is rated:
• Connected interface 0
• Static route 1
• IGRP 100
• RIP 120
• Unknown 255
The lower the value, the more reliable the source with 255 signifying information that the
router will ignore. So, the router will use IGRP, rated at 100, before RIP, rated at 120.
32 You are logged into a router, what command would show you the IP addresses of
routers connected to you?
• A. show cdp neighbors detail
• B. show run
• C. show neighbors
• D. show cdp
Ans A
33 As a system administrator, you perform an extended ping at the privileged
EXEC prompt. As part of the display, you see “Set DF bit in IP header? [yes] :”
What would happen if you answered no at the prompt.
• A. This lets the router fragment the packet.
• B. It tells the router not to fragment the packet.
• C. This lets the router direct the packet to the destination it finds in its routing
table.
• D. It tell the router to send the packet to the next hop router
Ans A
“Set DF bit in IP header?” is a response to an extended ping at the router. If you answer yes (the default) the router will not fragment the packet. If you answer no, the router will
fragment the packet.
34 You have typed “ping” 172.16.101.1 and get the following display: Type escape
sequence to abort. Sending 5, 100-byte ICMP Echoes to 172.16.101.1, timeout is 2
seconds:
.!!!!
What does the “.” signify?
• A. That one message timed out.
• B. That all messages were successful.
• C. That one message was successful.
• D. That one message completed in under the allotted timeframe.
Ans A
The possible responses from the ping command are: ! Successful receipt of an echo reply.
Timed out waiting for a reply U Destination unreachable C Congestion-experienced
packet I Ping interrupted ? Packet type unknown & Packet TTL exceeded
35 Which command, that is used to test address configuration, uses Time-To-Live
(TTL) values to generate messages from each router.
• A. trace
• B. ping
• C. telnet
• D. bootp
Ans: A
The Cisco IOS EXEC command “trace [protocol] [destination]” is used to discover routes
that packets will travel to their destination hosts. Trace uses TTL (Time to Live) values to
report destination route information.
36 What does the command “IP name-server 255.255.255.255” accomplish?
• A. It sets the domain name lookup to be a local broadcast.
• B. This is an illegal command.
• C. It disables domain name lookup. • D. The command is now defunct and has been replaced by “IP server-name ip
any”
Ans A
By default DNS is enabled on a router with a server address of 255.255.255.255, which
provides for a local broadcast.
37 As a system administrator, you need to provide your routers with a Domain
Name System (DNS) server. How many DNS servers can you specify with one
command?
• A. 6
• B. 1
• C. 2
• D. 4
Ans A
You can only specify six name servers in one command. The syntax is “IP name-server
server-address1 [[ server-address2 ]…server-address6]. You must also enable
DNS.
38 How would you configure one host name that points to two IP addresses?
• A. IP host jacob 1.0.0.5 2.0.0.8
• B. IP jacob 1.0.0.5 2.0.0.8
• C. IP host jacob 1.0.0.5
• D. IP host duplicate “all”
Ans A
The correct syntax is IP host name [ TCP-port-number ] address [ address ]….. So, “IP
host P1R1 1.0.0.5 2.0.0.8″ is the correct choice. “IP host jacob 1.0.0.5” only points the
host name jacob to one IP address–1.0.0.5.
39 The following selections show the command prompt and the configuration of the
IP network mask. Which two are correct?
• A. Router#term IP netmask-format { bitcount | decimal | hexadecimal }

D. 255.255.242.0, A, 15.16.192.0, 15.16.199.255
Ans A
44 You have an IP host address of 201.222.5.121 and a subnet mask of 255.255.255.248. What is the broadcast address?
A. 201.222.5.127
B. 201.222.5.120
C. 201.222.5.121
D. 201.222.5.122
Ans A
The easiest way to calculate this is to subtract 255.255.255.248 (subnet mask) from
255.255.255.255, this
equals 7. Convert the address 201.222.5.121 to binary–11001001 11011110 00000101
01111001. Convert the
mask 255.255.255.248 to binary–11111111 11111111 11111111 11111000. AND them together
to get: 11001001 11011110
00000101 01111000 or 201.222.5.120. 201.222.5.120 is the subnet address, add 7 to this
address for 201.222.5.127 or
the broadcast address. 201.222.5.121 through 201.222.5.126 are the valid host addresses.
45 Given the address 172.16.2.120 and the subnet mask of 255.255.255.0. How many hosts
are available?
A. 254
B. 510
C. 126
D. 16,372
Ans A
172.16.2 120 is a standard Class B address with a subnet mask that allows 254 hosts. You are a
network administrator and have been assigned the IP address of 201.222.5.0. You need to have
20 subnets with 5 hosts per subnet. The subnet mask is 255.255.255.248.
46 Which addresses are valid host addresses?
A. 201.222.5.17
B. 201.222.5.18
C. 201.222.5.16
D. 201.222.5.19
E. 201.222.5.31
Ans A,B & D
Subnet addresses in this situation are all in multiples of 8. In this example, 201.222.5.16 is the
subnet, 201.22.5.31 is the broadcast address. The rest are valid host IDs on subnet
201.222.5.16.
47 You are a network administrator and have been assigned the IP address of 201.222.5.0.
You need to have 20 subnets with
5 hosts per subnet. What subnet mask will you use?
A. 255.255.255.248
B. 255.255.255.128
C. 255.255.255.192
D. 255.255.255.240
Ans A
By borrowing 5 bits from the last octet, you can. have 30 subnets. If you borrowed only 4 bits you
could only have 14 subnets. The formula is (2 to the power of n)-2. By borrowing 4 bits, you have
(2x2x2x2)-2=14. By borrowing 5 bits, you have (2x2x2x2x2)-2=30. To get 20 subnets, you would
need to borrow 5 bits so the subnet mask would be 255.255.255.248.
48 You are given the IP address of 172.16.2.160 with a subnet mask of 255.255.0.0. What is the network address in binary?
A. 10101100 00010000
B. 00000010 10100000
C. 10101100 00000000
D. 11100000 11110000
Ans: A
To find the network address, convert the IP address to binary–10101100 000100000 00000010
10100000–then ANDed it with the subnet mask–11111111 11111111 00000000 00000000. The
rest is 10101100 00010000 00000000 00000000, which is 172.16.0.0 in decimal.
The first octet rule states that the class of an address can be determined by the numerical value
of the first octet.
