NO.1 Which term describes an EIGRP route that has
feasible successors?
A. active
B. passive
C. redistributed
D. invalid
Answer: B
Cisco prüfungsunterlagen 400-101 testking 400-101 Unterlage 400-101 prüfungsvorbereitung 400-101 dumps
Explanation:
A topology table entry for a destination can have one of two states. A route is considered in the
Passive state when a router is not performing a route recomputation. The route is in Active state
when a router is undergoing a route recomputation. If there are always feasible successors, a route
never has to go into Active state and avoids a route recomputation.
When there are no feasible successors, a route goes into Active state and a route recomputation
occurs. A route recomputation commences with a router sending a query packet to all neighbors.
Neighboring routers can either reply if they have feasible successors for the destination or optionally
return a query indicating that they are performing a route recomputation. While in Active state, a
router cannot change the next-hop neighbor it is using to forward packets. Once all replies are
received for a given query, the destination can transition to Passive state and a new successor can be
selected.

NO.2 What is the cause of ignores and overruns on an interface, when the overall traffic rate of the
interface is low?
A. a hardware failure of the interface
B. a software bug
C. a bad cable
D. microbursts of traffic
Answer: D
Cisco 400-101 echte Fragen 400-101 testantworten
Explanation:
Micro-bursting is a phenomenon where rapid bursts of data packets are sent in quick succession,
leading to periods of full line-rate transmission that can overflow packet buffers of the network stack,
both in network endpoints and routers and switches inside the network. Symptoms of micro bursts
will manifest in the form of ignores and/ or overruns (also shown as accumulated in "input error"
counter within show interface output). This is indicative of receive ring and corresponding packet
buffer being overwhelmed due to data bursts coming in over extremely short period of time
(microseconds). You will never see a sustained data traffic within show interface's "input rate"
counter as they are averaging bits per second (bps) over 5 minutes by default (way too long to
account for microbursts). You can understand microbursts from a scenario where a 3-lane highway
merging into a single lane at rush hour - the capacity burst cannot exceed the total available
bandwidth (i.e. single lane), but it can saturate it for a period of time.

A. Incorrect destination IP addresses are configured on the tunnel.
B. There is link flapping on the tunnel.

Explanation:
The %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive routing error message
means that the generic routing encapsulation (GRE) tunnel router has discovered a recursive routing
problem. This condition is usually due to one of these causes:

D. The interface facing the OTV groups must be configured with the highest MTU possible.

NO.5 Refer to the exhibit.
You must complete the configuration on R1 so that a maximum of three links can be used and
fragmentation is supported.
Which additional configuration accomplishes this task?

D. interface Multilink19 ip address 192.168.1.1 255.255.255.252 ppp multilink ppp multilink group 19
ppp multilink links maximum 3 ppp multilink interleave
Answer: A
Cisco testking 400-101 prüfungsfrage 400-101 Unterlage 400-101
Explanation:
The "ppp multilink interleave" command is needed to enable link fragmentation and Interleaving
(LFI). The Cisco IOS Link Fragmentation and Interleaving (LFI) feature uses Multilink PPP (MLP). MLP
provides a method of splitting, recombining, and sequencing datagrams across multiple logical data
links. MLP allows packets to be fragmented and the fragments to be sent at the same time over
multiple point-to-point links to the same remote address.
ppp multilink links maximum
To limit the maximum number of links that Multilink PPP (MLP) can dial for dynamic allocation, use
the ppp multilink links maximum command in interface configuration mode.

NO.6 Refer to the exhibit.
Which two corrective actions could you take if EIGRP routes from R2 fail to reach R1? (Choose two.)
A. Configure R2 to use a VRF to send routes to R1.
B. Configure the autonomous system in the EIGRP configuration of R1.
C. Correct the network statement on R2.
D. Add the interface on R1 that is connected to R2 into a VRF.
Answer: B,D
Cisco 400-101 Unterlage 400-101 Examsfragen
Explanation:
In this question we are running VRF Lite on R1. VRF Lite is also knows as "VRF without running MPLS".
This is an example of how to configure VRF Lite with EIGRP:
ip vrf FIRST rd 1:1 ! ip vrf SECOND rd 1:2 ! router eigrp 1 no auto-summary ! address-family ipv4 vrf
FIRST network 10.1.1.1 0.0.0.0 no auto-summary autonomous-system 200 exit-address-family !
address-family ipv4 vrf SECOND network 10.1.2.1 0.0.0.0 no auto-summary autonomous-system 100
exit-address-family ! interface FastEthernet0/0 ip vrf forwarding FIRST ip address 10.1.1.1
255.255.255.0 ! interface FastEthernet0/1 ip vrf forwarding SECOND ip address 10.1.2.1
255.255.255.0
The above example creates two VRFs (named "FIRST" and "SECOND"). VRF "FIRST" runs on EIGRP AS
200 while VRF "SECOND" runs on EIGRP AS 100. After that we have to add interfaces to the
appropriate VRFs. From this example, back to our question we can see that R1 is missing the
"autonomous-system ..." command under "address-family ipv4 vrf R2. And R1 needs an interface
configured under that VRF. Note. R2 does not run VRF at all! Usually R2 resides on customer side.
NO.7 Refer to the exhibit.
Which two configuration changes enable you to log in to the router? (Choose two.)
A. Configure a user name and password on the device.
B. Modify the default login authentication group to use the terminal line password.
C. Remove the terminal line password on the console line.
D. Modify the terminal lines to include transport input none.
E. Configure the terminal lines to use the local user database.

In this question we are running VRF Lite on R1. VRF Lite is also knows as "VRF without running MPLS".
This is an example of how to configure VRF Lite with EIGRP:

FIRST network 10.1.1.1 0.0.0.0 no auto-summary autonomous-system 200 exit-address-family !
