Topic 1, Network Principles

QUESTION NO: 1

Refer to the exhibit.

Based on this FIB table, which statement is correct?

A. There is no default gateway.
B. The IP address of the router on FastEthernet is 209.168.201.1.
C. The gateway of last resort is 192.168.201.1.
D. The router will listen for all multicast traffic.

Answer: C
Explanation:

The 0.0.0.0/0 route is the default route and is listed as the first CEF entry. Here we see the next
hop for this default route lists 192.168.201.1 as the default router (gateway of last resort).

Cisco 300-101 Exam
A network administrator checks this adjacency table on a router. What is a possible cause for the
incomplete marking?

A. incomplete ARP information
B. incorrect ACL
C. dynamic routing protocol failure
D. serial link congestion

Answer: A
Explanation:

To display information about the Cisco Express Forwarding adjacency table or the hardware Layer
3-switching adjacency table, use the show adjacency command.
Reasons for Incomplete Adjacencies
There are two known reasons for an incomplete adjacency:
No ARP Entry
When CEF cannot locate a valid adjacency for a destination prefix, it punts the packets to the CPU
for ARP resolution and, in turn, for completion of the adjacency.

QUESTION NO: 3

A network engineer notices that transmission rates of senders of TCP traffic sharply increase and
decrease simultaneously during periods of congestion. Which condition causes this?

A. global synchronization
B. tail drop
C. random early detection
D. queue management algorithm

Answer: A
Explanation:

TCP global synchronization in computer networks can happen to TCP/IP flows during periods of
congestion because each sender will reduce their transmission rate at the same time when packet
loss occurs.
Routers on the Internet normally have packet queues, to allow them to hold packets when the
network is busy, rather than discarding them.

Answer: Here are the solutions as below:
Explanation:
First we have to figure out why R3 and R4 can not communicate with each other. Use the show
running-config command on router R3.

Notice that R3 is configured as a stub receive-only router. The receive-only keyword will restrict
the router from sharing any of its routes with any other router in that EIGRP autonomous system.
This keyword will also prevent any type of route from being sent. Therefore we will remove this
command and replace it with the eigrp stub command:
R3# configure terminal R3(config)# router eigrp 123 R3(config-router)# no eigrp stub receive-only

"Pass Any Exam. Any Time." - www.actualtests.com 36

Cisco 300-101 Exam
R3(config-router)# eigrp stub
R3(config-router)# end

Now R3 will send updates containing its connected and summary routes to other routers. Notice
that the eigrp stub command equals to the eigrp stub connected summary because the connected
and summary options are enabled by default.
Next we will configure router R3 so that it has only 2 subnets of 10.0.0.0 network. Use the show ip
route command on R3 to view its routing table:

Because we want the routing table of R3 only have 2 subnets so we have to summary sub-
networks at the interface which is connected with R3, the s0/0 interface of R4.

There is one interesting thing about the output of the show ip route shown above: the 10.2.3.0/24,
which is a directly connected network of R3. We can’t get rid of it in the routing table no matter
what technique we use to summary the networks. Therefore, to make the routing table of R3 has
only 2 subnets we have to summary other subnets into one subnet.

In the output if we don’t see the summary line (like 10.0.0.0/8 is a summary…) then we should use
the command ip summary-address eigrp 123 10.2.0.0 255.255.0.0 so that all the ping can work
well.

In conclusion, we will use the ip summary-address eigrp 123 10.2.0.0 255.255.0.0 at the interface
s0/0 of R4 to summary.

R4> enable R4# conf t

For Internet service providers (ISPs) that provide public access.cisco. For example. including Smurf and Tribal Flood Network (TFN).

Care must be taken to ensure that the appropriate Unicast RPF mode (loose or strict) is configured during the deployment of this feature because it can drop legitimate traffic. Dropping this legitimate traffic could occur when asymmetric routing paths are present in the network. broadcast mode. and VRF mode Answer: A Explanation: Network administrators can use Unicast Reverse Path Forwarding (Unicast RPF) to help limit the malicious traffic on an enterprise network. strict mode. the packet must be received on the interface that the router would use to forward the return packet. Unicast RPF in VRF mode will not be covered in this document. Note that not all network devices support all three modes of operation. and broadcast mode C. Administrators can change this behavior using the allow-default option. This capability can limit the appearance of spoofed addresses on a network. An access list may also be specified that permits or denies certain source addresses in Unicast RPF loose mode. When administrators use Unicast RPF in loose mode.com/web/about/security/intelligence/unicast-rpf. loose mode. strict mode. a packet that contains a source address for which the return route points to the Null 0 interface will be dropped. or VRF mode." . Although asymmetric traffic flows may be of concern when deploying this feature. which allows the use of the default route in the source verification process.

What is CEF? CEF is one of the available switching options for Cisco routers. If the destination is reachable. CEF decides through which interface traffic is exiting the router.

Better performance than fast-switching (the default) and takes less CPU to perform the same task. Switching is what a router does when it makes the following decisions: 1. If the CEF is disabled on the router. go into global configuration mode and enter the CEF command. Overall. Whether to forward or not forward the packets after checking that the destination for the packet is reachable. 2. Based on the routing table.com 116 . what is the next hop of the router and which interface will the router use to get to that destination. Why CEF Needed when enabling NetFlow ? CEF is a prerequisite to enable NetFlow on the router interfaces. What is switching? A Router must make decisions about where to forward the packets passing through. ie.html "Pass Any Exam. CEF can switch traffic faster than route-caching using fast-switching How to enable CEF? CEF is disabled by default on all routers except the 7xxx series routers. the NetFlow packets exported from the router will have “Destination interface” as “null” and this leads NetFlow Analyzer to show no OUT traffic for the interfaces. The FIB is organized differently than the routing table and CEF uses the FIB to decide which interface to send traffic from. This is why this topic is about Cisco Express Forwarding. CEF offers the following benefits: 1. the NetFlow packets did not mark the destination interfaces and so NetFlow Analyzer was not able to show the OUT traffic for the interfaces. That is when we noticed the ‘no ip cef’ command on the router.actualtests. Cisco 300-101 Exam see the OUT traffic for the interfaces in NetFlow Analyzer. NetFlow Analyzer started showing OUT traffic for the interfaces.com/network-2/netflowanalyzer/2010/05/19/need-for-cef- in-netflow-data-export. ‘no ip cef‘. Any NetFlow analyzer product will calculate the OUT traffic for an interface based on the Destination Interface value present in the NetFlow packets exported from the router.www.manageengine.
