Question No: 5
Which Cisco Catalyst feature automatically disables the port in an operational PortFast upon receipt of a BPDU?
A. BackboneFast
B. UplinkFast
C. Root Guard
D. BPDU Guard
E. BPDU Filter
Answer: D
Explanation:
We only enable PortFast feature on access ports (ports connected to end stations). But if someone does not know he can accidentally plug that port to another switch and a loop may occur when BPDUs are being transmitted and received on these ports.
With BPDU Guard, when a PortFast receives a BPDU, it will be shut down to prevent a loop.
Question No: 6

An attempt to deny web access to a subnet blocks all traffic from the subnet. Which interface command immediately removes the effect of ACL 102?
A. no ip access-class 102 in
B. no ip access-class 102 out
C. no ip access-group 102 in
D. no ip access-group 102 out
E. no ip access-list 102 in
Answer: D
Explanation:
The u201cip access-groupu201d is used to apply and ACL to an interface. From the output shown, we know that the ACL is applied to outbound traffic, so u201cno ip access-group 102 outu201d will remove the effect of this ACL.
Question No: 7
When you are troubleshooting an ACL issue on a router, which command would you use to verify which interfaces are affected by the ACL?
A. show ip access-lists
B. show access-lists
C. show interface
D. show ip interface
E. list ip interface
Answer: D
Explanation:
Incorrect:
show ip access-lists does not show interfaces affected by an ACL.
Question No: 8
Which three are characteristics of an IPv6 anycast address? (Choose three.)
A. one-to-many communication model
B. one-to-nearest communication model
C. any-to-many communication model
D. a unique IPv6 address for each device in the group
E. the same address for multiple devices in the group
F. delivery of packets to the group interface that is closest to the sending device
Answer: B,E,F
Explanation:
A new address type made specifically for IPv6 is called the Anycast Address. These IPv6 addresses are global addresses, these addresses can be assigned to more than one interface unlike an IPv6 unicast address. Anycast is designed to send a packet to the nearest interface that is a part of that anycast group.
The sender creates a packet and forwards the packet to the anycast address as the destination address which goes to the nearest router. The nearest router or interface is found by using the metric of a routing protocol currently running on the network. However in a LAN setting the nearest interface is found depending on the order the neighbors were learned. The anycast packet in a LAN setting forwards the packet to the neighbor it learned about first.
Question No: 9
CORRECT TEXTCentral Florida Widgets recently installed a new router in their office. Complete the network installation by performing the initial router configurations and configuring R1PV2 routing using the router command line interface (CLI) on the RC.
Configure the router per the following requirements: Name of the router is R2
Enable. secret password is cisco
The password to access user EXEC mode using the console is cisco2 The password to allow telnet access to the router is cisco3
IPV4 addresses must be configured as follows:
Ethernet network 209.165.201.0/27 - router has fourth assignable host address in subnet Serial network is 192.0.2.176/28 - router has last assignable host address in the subnet. Interfaces should be enabled.
Router protocol is RIPV2
Attention:
In practical examinations, please note the following, the actual information will prevail.
1. Name or the router is xxx
2. Enable. secret password is xxx
3. Password In access user EXEC mode using the console is xxx
4. The password to allow telnet access to the router is xxx
5. IP information
Answer:
Router>enable
Router#config terminal
Router(config)#hostname R2
R2(config)#enable secret Cisco 1
R2(config)#line console 0
R2(config-line)#password Cisco 2
R2(config-line)#exit R2(config)#line vty 0 4
R2(config-line)#password Cisco 3
R2(config-line)#login
R2(config-line)#exit R2(config)#interface faO/0
R2(config-if)#ip address 209.165.201.4 255.255.255.224
R2(config)#interface s0/0/0
R2(config-if)#ip address 192.0.2.190 255.255.255.240
R2(config-if)#no shutdown
R2(config-if)#exit R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#network 209.165.201.0
R2(config-router)#network 192.0.2.176
R2(config-router)#end
R2#copy run start
Question No: 10
Refer to the exhibit.
What is the cause of the Syslog output messages?
A. The EIGRP neighbor on Fa0/1 went down due to a failed link.
B. The EIGRP neighbor connected to Fa0/1 is participating in a different EIGRP process, causing the adjacency to go down.
C. A shut command was executed on interface Fa0/1, causing the EIGRP adjacency to go
down.
D. Interface Fa0/1 has become error disabled, causing the EIGRP adjacency to go down.
Answer: C
Explanation:
The first lines of the message show that a configuration change was made, and that the fa0/1 interface changed to a state of administratively down. This can only be done by issuing the shutdown command. The last line indicates that this caused an EIGRP neighbor adjacency to go down.
Question No: 11
Which router IOS commands can be used to troubleshoot LAN connectivity problems? (Choose three.)
A. ping
B. tracert
C. ipconfig
D. show ip route
E. winipcfg
F. show interfaces
Answer: A,D,F
Explanation:
Ping, show ip route, and show interfaces are all valid troubleshooting IOS commands. Tracert, ipconfig, and winipcfg are PC commands, not IOS.
Question No: 12
What Cisco IOS feature can be enabled to pinpoint an application that is causing slow network performance?
A. SNMP
B. Netflow
C. WCCP
D. IP SLA
Answer: B
Explanation:
Netflow can be used to diagnose slow network performance, bandwidth hogs and bandwidth utilization quickly with command line interface or reporting tools.

Question No: 13
What will be the result if the following configuration commands are implemented on a Cisco switch?
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security mac-address sticky
A. A dynamically learned MAC address is saved in the startup-configuration file.
B. A dynamically learned MAC address is saved in the running-configuration file.
C. A dynamically learned MAC address is saved in the VLAN database.
D. Statically configured MAC addresses are saved in the startup-configuration file if frames from that address are received.
E. Statically configured MAC addresses are saved in the running-configuration file if frames from that address are received.
Answer: B
Explanation:
In the interface configuration mode, the command switchport port-security mac-address sticky enables sticky learning. When entering this command, the interface converts all the dynamic secure MAC addresses to sticky secure MAC addresses.
Question No: 14
Refer to the diagram.
All hosts have connectivity with one another. Which statements describe the addressing scheme that is in use in the network? (Choose three.)
A. The subnet mask in use is 255.255.255.192.
B. The subnet mask in use is 255.255.255.128.
C. The IP address 172.16.1.25 can be assigned to hosts in VLAN1
D. The IP address 172.16.1.205 can be assigned to hosts in VLAN1
E. The LAN interface of the router is configured with one IP address.
F. The LAN interface of the router is configured with multiple IP addresses.
Answer: B,C,F
Explanation:
The subnet mask in use is 255.255.255.128: This is subnet mask will support up to 126 hosts, which is needed.
The IP address 172.16.1.25 can be assigned to hosts in VLAN1: The usable host range in this subnet is 172.16.1.1-172.16.1.126
The LAN interface of the router is configured with multiple IP addresses: The router will need 2 subinterfaces for the single physical interface, one with an IP address that belongs in each VLAN.
