Exam questions
Time remaining: 00: 06: 30


1 . What does a Catalyst 8500 use for Layer 3 switching?
MLS
MSFC
NFFC
CEF

2 . What can you use with the Catalyst 5000 to do multiprotocol routing?
SRM
RSM
SAGE
SAINT

3 . What do you do to configure MLS-SE to participate in MLS with an in-house RSM?
MLS is enabled by default
Enter the “set mls enable” command in privileged mode
Enter the “set mls enable” and “set mls include rsm ip address” Commands in privileged mode
Enter the “set mls enable” and “set mls vtp-domain vtp domain name” commands in privileged mode
Enter the “set mls enable” and “set mls agingtime number-of-seconds” commands in privileged mode

4 . What are the three different flow masks that are supported by the MLS-SE?
Destination-IP
Source-Destination-IP

IP-Flow
IN-Flow

5 . What command would you use to see the flow mask type that is currently enabled on the MLS-SE?
show flow
show flow-mask
show mls

show mask

6 . What is true regarding Cisco’s NetFlow technology? Choose three. (Chi con 2 y thoi)
Allows you to gather detailed information on your traffic flows
Can only be used with extended access lists
Allows for the deployment of access lists without any performance penalty when used in tandem with Multilayer Switching
Requires a Layer 2 device to provide Layer 3 services

7 . A Supervisor Engine is not required for the 6x00 series of switches.
True
False

8 . The required components of Cisco Systems MLS implementation are: (Choose three).
The MLS-SE
The MLS-RP
The MLS-PR
The MLSP

9 . Read and answer the question

A
B

C
D

10 . If you had two Telnet sessions occurring between two PC’s, why would these sessions be treated as two different traffic flows
within MLS cache even though the Layer 3 addressing is the same?
The source port numbers would be different
The MLS-RP would change the IP addresses to MAC addresses
The MLS-PR converts the IP addresses to different traffic flows
The default gateway would age out all entries to make room for new entries

11 . What are three advantages of Multilayer switching?
Combines functionality of Layer 2, Layer 3, and Layer 4 switching
High-speed functionality
Switching is software-based
Low latency

12 . What is true regarding MLS cache?
Bidirectional flow
Knows data flows
Two-way flow
Unidirectional flow

13 . Cisco defines a traffic flow as a set of packets between a specific source and destination where the protocol and the port numbers
are different.
True
False

14 . What command would you use to add an interface to a new VTP domain on an RP (Route Processor)?
mls rp
mls vtp-domain

mls rp vtp-domain
mls ip rp

15 . Layer 4 switching has better performance than Layer 3 switching.
True
False

16 . What daughter card for the 6x00 series of switches is similar to the RSFC that is used in the 5000 series of switches?
MSFC
RSM
NFFC
MSM

17 . What are the three basic types of packets?
Unicasts
Local Broadcasts
Multicasts
Remote Broadcasts

18 . What is the purpose of defining an MLS Management Interface?
To disable MLS
To allow MLS to function
To stop the flow of MLSP packets
To prevent overruns

19 . Read and answer the question

A
B
C

D
E
F

20 . What are two ways that Cisco routers can control traffic based on Layer 4 information?
Extended access lists
Standard access lists
Layer 4 accounting using Fast switching
Layer 4 accounting using NetFlow switching

21 . For Layer 3 switching to work, the MLS-SE must see the traffic flow:
in only one direction from the MLS-SE
in only one direction from the MLS-RP
in both directions from the MLS-RP
in both directions from the MLS-SE

22 . What command would you use to allow input access lists?
mls rp ip input-acl
mls ip rp input-acl
mls ip input-acl
mls rp input-acl

23 . The first module in the Catalyst 5000 switches:
should contain at least 12 Ethernet ports
is not required to be utilized
contains an interface module
contains the console port in the Supervisor Engine

24 . What is true regarding the RSFC (Route Switch Feature Card)? Choose two.
It is a full function IOS router installed as an integrated daughter card

It is used on the Catalyst 5000 series Supervisor IIG and Supervisor IIIG Engines
Can only be used on the Supervisor II Engine
Can only be used on the Supervisor III Engine
