CISCO CCNA 200-301 Q107

Which Cisco Internetwork Operating System (IOS) command is used to view information about the Dynamic Host Configuration Protocol (DHCP) address pool?

A. show ip dhcp server statistics
B. show ip dhcp pool
C. show dhcp pool
D. show ip dhcp server pool

Correct Answer: B

The show ip dhcp pool command is used to view information about the DHCP address pool.

The show ip dhcp server statistics command is incorrect because this command is used to view the statistics of the DHCP server.

The show dhcp pool command and show ip dhcp server pool commands are both incorrect because these are not valid Cisco IOS commands.

CISCO CCNA 200-301 Q90

Which three statements are TRUE regarding a Local Area Network (LAN)? (Choose three.)

A. A LAN is confined to one building or campus.
B. A LAN can cover great distances.
C. A LAN provides fast data transmission.
D. A LAN is easily expandable.
E. LANs require the use of a router to communicate between local hosts.

Correct Answer: A, C, D

A LAN is confined to one building or campus, provides fast data transmission, and is easily expandable. A LAN refers to the interconnection of computers within a building or a group of buildings. A LAN generally uses twisted pair cables for data transmission.

The following are some characteristics of LANs:

– LANs are generally confined to a building, a group of buildings, or a campus.
– Every computer in the LAN can communicate with every other computer on the network.
– A LAN is easy to set up, as physical connectivity can be easily established.
– The cost of the transmission medium used is low, as a LAN generally uses CAT5, CAT5e, or CAT6 cables for data transmission.
– A LAN provides fast data transmission rates.

The option stating that a LAN can cover great distances is incorrect. A Wide Area Network (WAN) is a network that does not have any geographical boundaries. The Internet is the best example of a WAN.

LANs do not require the use of a router to communicate (although they can be used to connect subnets) between local hosts. Hosts can communicate through a hub or switch.

CISCO CCNA 200-301 Q83

What configuration is needed to span a user defined Virtual LAN (VLAN) between two or more switches?

A. A VTP domain must be configured.
B. VTP pruning should be enabled.
C. The VTP mode of operation should be server.
D. A trunk connection should be set up between the switches.

Correct Answer: D

To span a user defined VLAN between two or more switches, a trunk connection must be established. Trunk connections can carry frames for multiple VLANs. If the link between switches is not trunked, by default only VLAN 1 information will be switched across the link.

A VLAN trunking protocol (VTP) domain is not necessary to span VLANs across multiple switches. VTP is used to have consistent VLAN configuration throughout the domain.

VTP pruning is used to detect whether a trunk connection is carrying unnecessary traffic for VLANs that do not exist on downstream switches. By default, all trunk connections carry traffic from all VLANs in the management domain. However, a switch does not always need a local port configured for each VLAN. In such situations, it is not necessary to flood traffic from VLANs other than the ones supported by that switch. VTP pruning enables switching fabric to prevent flooding traffic on trunk ports that do not need it.

VTP server mode is not required for a server to span multiple switches. In VTP server mode of operation, VLANs can be created, modified, deleted, and other VLAN configuration parameters can be modified for the entire VTP domain. VTP messages are sent over all trunk links, and configuration changes are propagated to all switches in the VTP domain.

CISCO CCNA 200-301 Q15

Consider the following diagram:

Which of the following routing protocols could NOT be used with this design?

A. RIPv1
B. RIPv2

Correct Answers: A

The network design displayed has subnets of a major classful network located in opposite directions from the perspective of some of the individual routers. This configuration can be accommodated by any routing protocol that supports Variable Length Subnet masks (VLSM) or the transfer of subnet mask information in routing advertisements.

RIPv1 supports neither of these. RIPv1 will automatically summarize routing advertisements to their classful network (in this case This action will cause some of the routers to have routes to the same network with different next hop addresses, which will NOT work.
EIGRP, RIPv2 and OSPF all support VLSM and can be used in the design

CISCO CCNA 200-301 Q5

Refer to the exhibit. If OSPF is running on this network, how does Router 2 handle traffic from Site B to at Site A?

A. It sends packets out of interface Fa0/2 only.
B. It sends packets out of interface Fa0/1 only.
C. It cannot send packets to
D. It load-balances traffic out of Fa0/1 and Fa0/2

Correct Answers: C

Router2 does not have an entry for the subnet It only has an entry for, which ranges from to

CCNA – Access List Simulation 2

A network associate is adding security to the configuration of the Corp1 router. The user on host C should be able to use a web browser to access financial information from the Finance Web Server. No other hosts from the LAN nor the Core should be able to use a web browser to access this server. Since there are multiple resources for the corporation at this location including other resources on the Finance Web Server, all other traffic should be allowed.

The task is to create and apply an access-list with no more than three statements that will allow ONLY host C web access to the Finance Web Server ( No other hosts will have web access to the Finance Web Server. All other traffic is permitted.

CISCO CCNA Exam – Q337

Answer and Explanation:

Corp1>enable (you may enter “cisco” as it passwords here)

We should create an access-list and apply it to the interface which is connected to the Server LAN because it can filter out traffic from both Sw-2 and Core networks. The Server LAN network has been assigned addresses of – so we can guess the interface connected to them has an IP address of (.30 is the number shown in the figure). Use the “show ip interface brief” command to check which interface has the IP address of
CISCO CCNA Exam – Q337b

We learn that interface FastEthernet0/1 is the interface connected to Server LAN network. It is the interface we will apply our access-list (for outbound direction).

Corp1# configure terminal

Our access-list needs to allow host C – to the Finance Web Server via web (port 80)
Corp1(config)# access-list 100 permit tcp host host eq 80

Deny other hosts access to the Finance Web Server via web
Corp1(config)# access-list 100 deny tcp any host eq 80

All other traffic is permitted
Corp1(config)# access-list 100 permit ip any any

Apply this access-list to Fa0/1 interface (outbound direction)
Corp1(config)# interface fa0/1
Corp1(config-if)# ip access-group 100 out

Finally, save the configuration
Corp1(config-if)# end
Corp1# copy running-config startup-config

Notice: We have to apply the access-list to Fa0/1 interface (not Fa0/0 interface) so that the access-list can filter traffic coming from both the LAN and the Core networks. If we apply access list to the inbound interface we can only filter traffic from the LAN network.

Click on host C to open its web browser. In the address box type to check if you are allowed to access Finance Web Server or not. If your configuration is correct then you can access it.

Click on other hosts (A, B and D) and check to make sure you can’t access Finance Web Server from these hosts.

CISCO CCNA Exam – Q336c

CISCO CCNA Exam – Q336d

CISCO CCNA Exam – Q336e

Access List Simulation – Question 1

How can we fix the problem but only allow ping to work while disabling telnet?

A. Correctly assign an IP address to interface fa0/1
B. Change the ip access-group command on fa0/0 from “in” to “out”
C. Remove access-group 106 in from interface fa0/0 and add access-group 115 in.
D. Remove access-group 102 out from interface s0/0/0 and add access-group 114 in
E. Remove access-group 106 in from interface fa0/0 and add access-group 104 in

Answer: E


Let’s have a look at the access list 104:
CISCO CCNA Exam – Q336f

The question does not ask about ftp traffic so we don’t care about the two first lines. The 3rd line denies all telnet traffic and the 4th line allows icmp traffic to be sent (ping). Remember that the access list 104 is applied on the inbound direction so the 5th line “access-list 104 deny icmp any any echo-reply” will not affect our icmp traffic because the “echo-reply” message will be sent over the outbound direction.

Access List Simulation – Question 2
What will happen after issuing the command “ip access-group 114 in” to the fa0/0 interface?

A. Attempts to telnet to the router would fail
B. All traffic from the network would be allow to go through
C. TCP and UDP traffic are not allowed to pass
D. Routing protocol updates for the network would not be accepted from the fa0/0 interface

Answer: B

From the output of access-list 114: access-list 114 permit ip any we can easily understand that this access list allows all traffic (ip) from network.

Access List Simulation – Question 3

What will happen after issuing the command “access-group 115 in” on the s0/0/1 interface?

A. Hosts cannot connect to Router through s0/0/1
B. Telnet and ping would work but routing updates would fail.
C. FTP, FTP-DATA, echo, and HTTP traffic would work but telnet would fail
D. Only traffic from the network would pass through the interface

Answer: A

First let’s see what was configured on interface S0/0/1:
CISCO CCNA Exam – Q336g

Recall that each interface only accepts one access-list, so when using the command “ip access-group 115 in” on the s0/0/1 interface it will overwrite the initial access-list 102. Therefore any telnet connection will be accepted (so we can eliminate answer C).
B is not correct because if telnet and ping can work then routing updates can, too.
D is not correct because access-list 115 does not mention about network. So the most reasonable answer is A.

But here raise a question…

The wildcard mask of access-list 115, which is, means that only host with ip addresses in the form of x.x.x.0 will be accepted. But we all know that x.x.x.0 is likely to be a network address so the answer A: “no host could connect to Router through s0/0/1” seems right…

But what will happen if we don’t use a subnet mask of For example we can use an ip address of, such a host with that ip address exists and we can connect to the router through that host. Now answer A seems incorrect!

CISCO CCNA Exam – Q335

A network administrator needs to configure a serial link between the main office and a remote location. The router at the remote office is a non-Cisco router. How should the network administrator configure the serial interface of the main office router to make the connection?

Main(config)# interface serial 0/0
Main(config-if)# ip address
Main(config-if)# no shut
Main(config)# interface serial 0/0
Main(config-if)# ip address
Main(config-if)# encapsulation ppp
Main(config-if)# no shut
Main(config)# interface serial 0/0
Main(config-if)# ip address
Main(config-if)# encapsulation frame-relay
Main(config-if)# authentication chap
Main(config-if)# no shut
Main(config)# interface serial 0/0
Main(config-if)#ip address
Main(config-if)#encapsulation ietf
Main(config-if)# no shut

Correct Answer: B

With serial point to point links there are two options for the encapsulation. The default, HDLC, is Cisco proprietary and works only with other Cisco routers. The other option is PPP which is standards based and supported by all vendors.

CISCO CCNA Exam – Q334

What are three reasons that an organization with multiple branch offices and roaming users might implement a Cisco VPN solution instead of point-to-point WAN links? (Choose three.)

A. reduced cost
B. better throughput
C. broadband incompatibility
D. increased security
E. scalability
F. reduced latency

Correct Answers: A, D, E

IPsec offer a number of advantages over point to point WAN links, particularly when multiple locations are involved. These include reduced cost, increased security since all traffic is encrypted, and increased scalability as a single WAN link can be used to connect to all locations in a VPN, where as a point to point link would need to be provisioned to each location.
