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.

TCP-starvation/UDP-dominance likely occurs if (TCP-based) mission-critical data is assigned to the same service provider class as (UDP-based) streaming video and the class experiences sustained congestion. the same behavior would be observed. most UDP transmitters are completely oblivious to drops and thus never lower transmission rates due to dropping. the introduction of a sudden burst of traffic may cause large numbers of established. potentially giving up their bandwidth to drop-oblivious UDP flows." .com 4 .

(Choose three. When TCP flows are combined with UDP flows in a single service provider class and the class experiences congestion.wikipedia.www. lower throughput Answer: A.C. as WRED (for the most part) only affects TCP-based flows. the size of these queues is also limited.

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.

CEF decides through which interface traffic is exiting the router. NetFlow Analyzer started showing OUT traffic for the interfaces. If the destination is reachable. ie. simply use the ‘no’ form of the command. Better performance than fast-switching (the default) and takes less CPU to perform the same task. Overall. Without enabling the CEF on the router. 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. Every NetFlow configuration aspect was checked and nothing incorrect was found. 2.html "Pass Any Exam. This decision- making process is called “switching”. That is when we noticed the ‘no ip cef’ command on the router. What is switching? A Router must make decisions about where to forward the packets passing through. ‘no ip cef‘. 2. Enabling and Disabling CEF is easy. What is CEF? CEF is one of the available switching options for Cisco routers. Router# config t Router(config)# ip cef Router(config)# To disable CEF. called the Forwarding Information Base (FIB). The FIB is organized differently than the routing table and CEF uses the FIB to decide which interface to send traffic from. allows for advanced features like NBAR 3.

Why CEF Needed when enabling NetFlow ? CEF is a prerequisite to enable NetFlow on the router interfaces." . If the CEF is disabled on the router. what is the next hop of the router and which interface will the router use to get to that destination. CEF creates its own table.
