200-105 Exam Braindumps

Question No. 1

Refer to the exhibit.

A packet with a source IP address of and a destination IP address of arrives at the AcmeB router. What action does the router take?

Answer: C

CCNA – EIGRP Common Question


Looking at the output above, there is no IP route for address on AcmeB routing table. If the router can no find a specific path in its routing table to a particular route,( In this case no path is found so AcmeB) the router will inform the source host with an ICMP message that the destination is unreachable and this will be through the same interface it has received the packet (interface Fa0/0 network from the exhibit).

Question No. 2

Refer to the exhibit. A network engineer is troubleshooting an Internet connectivity problem on the computer.

What is causing the problem?

Answer: B

Question No. 3

Which two requirements must be met to allow two routers running EIGRP for Ipv6 to become neighbors?

(Choose two.)

Answer: C, D

Question No. 4

Refer to the exhibit.

Why has this switch not been elected the root bridge for VLAN1?

Answer: D


When a switch receives a BPDU, it first compares priority, the lower number wins. If a tie, compare MAC, the smaller one wins. Here Switch has 32769 priority which is greater than 20481 so switch will not elect for root bridge. It says the bridge priority for Switch is 32769, and the root priority is 20481. Which means that some other switch has the lower priority and won the election for VLAN 1.

Question No. 5

Which command do you enter to enable an interface to support PPPoE on a client?

Answer: B

Question No. 6

Which two protocols can support trunking? (Choose two.)

Answer: B, C

Question No. 7

Disadvantages of using proxy ARP?

Answer: B

Question No. 8

The network administrator is asked to configure 113 point-to-point links. Which IP addressing scheme best

defines the address range and subnet mask that meet the requirement and waste the fewest subnet and host


Answer: D

Question No. 9

Which command do you enter to permit IPv6 functionality on an EIGRPv3 interface?

Answer: D

Question No. 10

Which WAN solution is secured by default?

Answer: A

Question No. 11

What are three values that must be the same within a sequence of packets for Netflow to consider them a network flow? (Choose three.)

Answer: A, D, E

Each packet that is forwarded within a router or switch is examined for a set of IP packet attributes. These attributes are the IP packet identity or fingerprint of the packet and determine if the packet is unique or similar to other packets.

Traditionally, an IP Flow is based on a set of 5 and up to 7 IP packet attributes.

IP Packet attributes used by NetFlow:

* IP source address

* IP destination address

* Source port

* Destination port

* Layer 3 protocol type

* Class of Service

* Router or switch interface

All packets with the same source/destination IP address, source/destination ports, protocol interface and class of service are grouped into a flow and then packets and bytes are tallied. This methodology of fingerprinting or determining a flow is scalable because a large amount of network information is condensed into a database of NetFlow information called the NetFlow cache.
