Q26. - (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.
Q27. - (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.
Q28. - (Topic 4)
What command is used to verify the DLCI destination address in a Frame Relay static configuration?
A. show frame-relay pvc
B. show frame-relay lmi
C. show frame-relay map
D. show frame relay end-to-end
Answer: C
Explanation:
Sample “show frame-relay map” output: R1#sh frame map
Serial0/0 (up): ip 10.4.4.1 dlci 401(0x191,0x6410), dynamic, broadcast,, status defined, active
Serial0/0 (up): ip 10.4.4.3 dlci 403(0x193,0x6430), dynamic, broadcast,, status defined, active
Serial0/0 (up): ip 10.4.4.4 dlci 401(0x191,0x6410), static, CISCO, status defined, active
Q29. - (Topic 5)
Which IPv6 address is the all-router multicast group?
A. FF02::1
B. FF02::2
C. FF02::3
D. FF02::4
Answer: B
Explanation:
Well-known IPv6 multicast addresses:
Address Description ff02::1
All nodes on the local network segment
ff02::2
All routers on the local network segment
Q30. - (Topic 5)
Which two are features of IPv6? (Choose two.)
A. anycast
B. broadcast
C. multicast
D. podcast
E. allcast
Answer: A,C
Explanation:
IPv6 addresses are classified by the primary addressing and routing methodologies common in networking: unicast addressing, anycast addressing, and multicast addressing.
✑ A unicast address identifies a single network interface. The Internet Protocol
delivers packets sent to a unicast address to that specific interface.
✑ An anycast address is assigned to a group of interfaces, usually belonging to different nodes. A packet sent to an anycast address is delivered to just one of the member interfaces, typically the nearest host, according to the routing protocol’s definition of distance. Anycast addresses cannot be identified easily, they have the same format as unicast addresses, and differ only by their presence in the network at multiple points. Almost any unicast address can be employed as an anycast address.
✑ A multicast address is also used by multiple hosts, which acquire the multicast address destination by participating in the multicast distribution protocol among the network routers. A packet that is sent to a multicast address is delivered to all interfaces that have joined the corresponding multicast group.
Q31. - (Topic 8)
Which destination IP address can a host use to send one message to multiple devices across different subnets?
A. 172.20.1.0
B. 127.0.0.1
C. 192.168.0.119
D. 239.255.0.1
Answer: D
Explanation: Multicast is a networking protocol where one host can send a message to a special multicast IP address and one or more network devices can listen for and receive those messages.
Multicast works by taking advantage of the existing IPv4 networking infrastructure, and it does so in something of a weird fashion. As you read, keep in mind that things are a little
confusing because multicast was "shoe-horned" in to an existing technology.
For the rest of this article, let's use the multicast IP address of 239.255.0.1. We'll not worry about port numbers yet, but make a mental note that they are used in multicast. We'll discuss that later.
Q32. - (Topic 4)
Refer to the exhibit.
Which statement describes DLCI 17?
A. DLCI 17 describes the ISDN circuit between R2 and R3.
B. DLCI 17 describes a PVC on R2. It cannot be used on R3 or R1.
C. DLCI 17 is the Layer 2 address used by R2 to describe a PVC to R3.
D. DLCI 17 describes the dial-up circuit from R2 and R3 to the service provider.
Answer: C
Explanation:
DLCI-Data Link Connection Identifier Bits: The DLCI serves to identify the virtual connection so that the receiving end knows which information connection a frame belongs to. Note that this DLCI has only local significance. Frame Relay is strictly a Layer 2 protocol suite.
