Q61. - (Topic 8)
Which feature can you use to monitor traffic on a switch by replicating it to another port or ports on the same switch?
A. copy run start
B. traceroute
C. the ICMP Echo IP SLA
D. SPAN
Answer: D
Explanation: A source port, also called a monitored port, is a switched or routed port that you monitor for network traffic analysis. In a single local SPAN session or RSPAN source session, you can monitor source port traffic, such as received (Rx), transmitted (Tx), or bidirectional (both). The switch supports any number of source ports (up to the maximum
number of available ports on the switch) and any number of source VLANs. A source port has these characteristics:
✑ It can be any port type, such as EtherChannel, Fast Ethernet, Gigabit Ethernet,
and so forth.
✑ It can be monitored in multiple SPAN sessions.
✑ It cannot be a destination port.
✑ Each source port can be configured with a direction (ingress, egress, or both) to monitor. For EtherChannel sources, the monitored direction applies to all physical ports in the group.
✑ Source ports can be in the same or different VLANs.
✑ For VLAN SPAN sources, all active ports in the source VLAN are included as source ports.
Q62. - (Topic 3)

A. show reload
B. show boot
C. show running-config
D. show version
Answer: D
Explanation:
The “show version” command can be used to show the last method to powercycle (reset) a router.
Q63. - (Topic 3)
Refer to the exhibit.
The speed of all serial links is E1 and the speed of all Ethernet links is 100 Mb/s. A static route will be established on the Manchester router to direct traffic toward the Internet over the most direct path available. What configuration on the Manchester router will establish a route toward the Internet for traffic that originates from workstations on the Manchester LAN?
A. ip route 0.0.0.0 255.255.255.0 172.16.100.2
B. ip route 0.0.0.0 0.0.0.0 128.107.1.1
C. ip route 0.0.0.0 255.255.255.252 128.107.1.1
D. ip route 0.0.0.0 0.0.0.0 172.16.100.1
E. ip route 0.0.0.0 0.0.0.0 172.16.100.2
F. ip route 0.0.0.0 255.255.255.255 172.16.100.2
Answer: E
Explanation:
We use default routing to send packets with a remote destination network not in the routing table to the next-hop router. You should generally only use default routing on stub networks—those with only one exit path out of the network.
According to exhibit, all traffic towards Internet that originates from workstations should forward to Router R1.
Syntax for default route is:
ip route <Remote_Network> <Netmask> <Next_Hop_Address>.
Q64. - (Topic 4)
Users have been complaining that their Frame Relay connection to the corporate site is very slow. The network administrator suspects that the link is overloaded.
Based on the partial output of the Router# show frame relay pvc command shown in the graphic, which output value indicates to the local router that traffic sent to the corporate site is experiencing congestion?
A. DLCI = 100
B. last time PVC status changed 00:25:40
C. in BECN packets 192
D. in FECN packets 147
E. in DE packets 0
Answer: C
Explanation:
If device A is sending data to device B across a Frame Relay infrastructure and one of the intermediate Frame Relay switches encounters congestion, congestion being full buffers, over-subscribed port, overloaded resources, etc, it will set the BECN bit on packets being returned to the sending device and the FECN bit on the packets being sent to the receiving device.
Q65. - (Topic 8)
What is one requirement for interfaces to run IPv6?
A. An IPv6 address must be configured on the interface.
B. An IPv4 address must be configured.
C. Stateless autoconfiguration must be enabled after enabling IPv6 on the interface.
D. IPv6 must be enabled with the ipv6 enable command in global configuration mode.
Answer: A
Explanation: To use IPv6 on your router, you must, at a minimum, enable the protocol and assign IPv6 addresses to your interfaces.
Q66. - (Topic 8)

Q68. - (Topic 5)
You have been asked to come up with a subnet mask that will allow all three web servers to be on the same network while providing the maximum number of subnets. Which network address and subnet mask meet this requirement?
A. 192.168.252.0 255.255.255.252
B. 192.168.252.8 255.255.255.248
C. 192.168.252.8 255.255.255.252
D. 192.168.252.16 255.255.255.240
E. 192.168.252.16 255.255.255.252
Answer: B
Explanation:
A subnet mask of 255.255.255.248 will allow for up to 6 hosts to reside in this network. A subnet mask of 255.255.255.252 will allow for only 2 usable IP addresses, since we cannot
use the network or broadcast address.
Q69. - (Topic 4)
RouterA is unable to reach RouterB. Both routers are running IOS version 12.0.
After reviewing the command output and graphic, what is the most likely cause of the problem?
A. incorrect bandwidth configuration
B. incorrect LMI configuration
C. incorrect map statement
D. incorrect IP address
Answer: C
Explanation:
First we have to say this is an unclear question and it is wrong. The “frame-relay map ip” statement is correct thus none of the four answers above is correct. But we guess there is a typo in the output. Maybe the “ip address 172.16.100.2 255.255.0.0 command should be “ip address 172.16.100.1 255.255.0.0. That makes answer C correct.
Q70. - (Topic 7)
Refer to the exhibit.
If the devices produced the given output, what is the cause of the EtherChannel problem?
A. SW1's Fa0/1 interface is administratively shut down.
B. There is an encapsulation mismatch between SW1's Fa0/1 and SW2's Fa0/1 interfaces.
C. There is an MTU mismatch between SW1's Fa0/1 and SW2's Fa0/1 interfaces.
D. There is a speed mismatch between SW1's Fa0/1 and SW2's Fa0/1 interfaces.
Answer: D
Explanation:
You must configure all interfaces in an EtherChannel to operate at the same speeds and duplex modes. Based on the output shown, SW1 is configured to run at 10Mb while SW2 is operating at 100 Mb.
