You have been asked to install and configure a new switch in a customer network. Use the
console access to the existing and new switches to configure and verify correct device
configuration.

the switch has been partially configured and you need to complete the rest of configuration to enable PC1 communication with PC2. Which of the configuration is correct? 5 .You are connecting the New_Switch to the LAN topology.

Option D 6 . Option C D.A. Option A B. Option B C.

E. Option E Answer: D Explanation: Within any VTP. This leaves only choice D and E. Note that the VTP versions supported in this network are 1. leaving only choice D as correct. access list 7 . We also see from the topology diagram that eth 0/0 of the new switch connects to a PC in VLNA 100. So. 2. Question No : 5 A network engineer must improve bandwidth and resource utilization on the switches by stopping the inefficient flooding of frames on trunk ports where the frames are not needed. the VTP domain name must match. VTP pruning B. step one is to find the correct VTP name on the other switches. Logging in to SW1 and using the “show vtp status” command we see this: So we know that the VTP domain must be CCNP. Which Cisco IOS feature can be used to achieve this task? A. 3 so either VTP version 2 or 3 can be configured on the new switch. so we know that this port must be an access port in VLAN 100.

The switches are using mismatched EtherChannel negotiation modes. storm control D. VTP pruning B. Why is the EtherChannel bundle not working? A. interface port channel 1 is in the down/down state. A new MAC address is removed from the content-addressable memory. Answer: A Question No : 7 Which feature must be enabled to eliminate the broadcasting of all unknown traffic to switches that are not participating in the specific VLAN? A. VLAN access-map Answer: A Question No : 6 If a network engineer applies the command mac-address-table notification mac-move on a Cisco switch port. A MAC address or host moves between different switch ports. D. A new MAC address is added to the content-addressable memory. bpdguard Answer: A Question No : 8 After an EtherChannel is configured between two Cisco switches. switchport trunk allowed VLAN D. port-security C. More than 64 MAC addresses are added to the content-addressable memory. C.

Due to administrative restrictions and requirements you should not add/delete vlans or create trunk links. 13 . Note: Due to administrative restrictions and requirements you should not add or delete VLANs. Routing must only be enabled for the specific subnets shown in the diagram.250. RouterC is correctly configured.0/24 – 190. All routes must be learned via EIGRP 65010 routing protocol.200. You do not have access to RouteC.Answer: D Question No : 15 CORRECT TEXT You have been tasked with configuring multilayer SwitchC. Company policies forbid the use of static or default routing. Routed interfaces should use the lowest host on a subnet when possible.10. You need to configure SwitchC so that Hosts H1 and H2 can successfully ping the server S1. changes VLAN port assignments or create trunks.64/27 Hosts H1 and H2 are configured with the correct IP address and default gateway.250.200.10. No trunking has been configured on RouterC. which has a partial configuration and has been attached to RouterC as shown in the topology diagram. All routes must be learned via the EIGRP routing protocol. SwitchC uses Cisco as the enable password.32/27 – 190. Company policies forbid the use of static or default routing. Also SwitchC needs to be able to ping server S1. The following subnets are available to implement this solution: – 10.

+ Only use SwitchC for interVLAN routing without using RouterC. Trunking must be established between RouterC and SwitchC. 15 .Answer: There are two ways to configure interVLAN routing in this case: + Use RouterC as a “router on a stick” and SwitchC as a pure Layer2 switch. No trunking requires. SwitchC should be configured as a Layer 3 switch (which supports ip routing function as a router).

64 0.255.33 255.0 ->RouterC has used IP 10.10.0.65 Now we have enough information to configure SwitchC (notice the EIGRP AS in this case is 650) Note: VLAN2 and VLAN3 were created and gi0/10.10.200.0/16 is not used anywhere else in this topology.The question clearly states “No trunking has been configured on RouterC” so RouterC does not contribute to interVLAN routing of hosts H1 & H2 -> SwitchC must be configured as a Layer 3 switch with SVIs for interVLAN routing.255. In order to complete the lab. so you will not miss within it in the exam.0.224 SwitchC(config-if)# no shutdown SwitchC(config-if)# int vlan 3 SwitchC(config-if)# ip address 190.2 255. in fact it is not necessary because the network 190.33 Host2: + Default gateway: 190.31 NOTE: THE ROUTER IS CORRECTLY CONFIGURED.0.

DHCP snooping Answer: A Question No : 33 CORRECT TEXT SWITCH. VLAN 20 is a new VLAN that will be used to provide the shipping personnel access to the server.0/24. it is necessary to restrict access to VLAN 20 in the following manner: • Users connecting to VLAN 20 via portfO/1 on ASW1 must be authenticated before they are given access to the network. • Packets from devices in the subnet of 172.46 • Radius key: rad123 • Authentication should be implemented as close to the host as possible.120.0/24 should be allowed on VLAN 20. The Radius server and application servers will be installed at a future date.D.40. Corporate polices do not allow layer 3 functionality to be enabled on the switches. • Filtering should be implemented as close to the serverfarm as possible. You must use the available IOS switch features. • Packets from devices in any other address range should be dropped on VLAN 20. You have been tasked with implementing the above access control as a pre-condition to installing the servers.120. Authentication is to be done via a Radius server: • Radius server host: 172. The topology diagram indicates their layer 2 mapping. • Devices on VLAN 20 are restricted to the subnet of 172.

Answer: A

Question No : 38 CORRECT TEXT
Scenario:
You work for SWITCH.com. They have just added a new switch (SwitchB) to the existing
network as shown in the topology diagram.
RouterA is currently configured correctly and is providing the routing function for devices on
SwitchA and SwitchB. SwitchA is currently configured correctly, but will need to be modified
to support the addition of SwitchB. SwitchB has a minimal configuration. You have been
tasked with competing the needed configuring of SwitchA and SwitchB. SwitchA and
SwitchB use Cisco as the enable password.

Configuration Requirements for SwitchA
The VTP and STP configuration modes on SwitchA should not be modified.
• SwitchA needs to be the root switch for vlans 11, 12, 13, 21, 22 and 23. All other vlans
should be left are their default values.

Configuration Requirements for SwitchB
• Vlan 21
Name: Marketing
will support two servers attached to fa0/9 and fa0/10
• Vlan 22
Name: Sales
will support two servers attached to fa0/13 and fa0/14
• Vlan 23
o Name: Engineering
o will support two servers attached to fa0/15 and fa0/16
• Access ports that connect to server should transition immediately to forwarding state
upon detecting the connection of a device.
• SwitchB VTP mode needs to be the same as SwitchA.

servers. The distribution switches are configured to use HSRP to provide a high availability
solution.
• DSW1 -primary device for VLAN 101 VLAN 102 and VLAN 105
• DSW2 - primary device for VLAN 103 and VLAN 104
• A failure of GigabitEthemet1/0/1 on primary device should cause the primary device to
release its status as the primary device, unless GigabitEthernet1/0/1 on backup device has
also failed.
Troubleshooting has identified several issues. Currently all interfaces are up. Using the
running configurations and show commands, you have been asked to investigate and
