I've decided to post up the The Weekly Question from csg-e@yahoogroups.com

So that they can be referenced.

Hi 

Here are mine for this week

Couldn't think of anything else :(

Koen

What's wrong with following config:

The terminal server is configured with the following config, but for some reason the terminal server cannot acces any of the routers it is connected to

!

version 11.2

service udp-small-servers

service tcp-small-servers

!

hostname Term_Srvr

!

enable password cisco

!

no ip domain-lookup

!

interface loopback)

ip address 1.1.1.1 255.0.0.0

!

interface Ethernet0

no ip address

!

interface Serial0

no ip address

shutdown

!

interface Serial1

no ip address

shutdown

!

ip host r1 2001 11.11.1.1

ip host r2 2002 11.11.1.1

ip host r3 2003 11.11.1.1

ip host r5 2005 11.11.1.1

ip host r4 2004 11.11.1.1

ip host fr 2006 11.11.1.1

- What's wrong with the following routing table

Gateway of last resort is not set

10.0.0.0/24 is subnetted, 1 subnets

B 10.1.1.0 [20/0] via 172.16.5.5, 00:03:16

B 192.168.1.0/24 is directly connected, Serial0

172.16.0.0/24 is subnetted, 3 subnets

C 172.16.5.0 is directly connected, Ethernet0

C 172.16.1.0 is directly connected, Serial1

OK, Its that time of the week again...

1. Give us three things about AppleTalk...

     a. AppleTalk networks are hierarchically arranged.

     b. An AppleTalk socket is a unique, addressable location in an AppleTalk node.

     c. AppleTalk networks can be nonextended or extended. 

2. Give us three reasons why you would create VLAN's...

     a. Simplified administration.

     b. Control of broadcasts.

     c. Security.

3. What are the seven steps of the Cisco troubleshooting model (Choose all that apply) and put them into the correct order...

     a. Document changes

     b. Create a baseline

     c. Create an action plan

     d. Undo the wrong changes

     e. Define the problem

     f. Observe changes

     g. Observe results

     h. Implement an action plan

     i. Gather information

     j. Consider solutions

     k. Consider possibilities

     l. Define the problem boundary

     m. Iterate the process

Have fun...

OK, my turn, I know its early...

As usual, unless the question is multiple choice, answers must be unique within the group.

1. Tell us three things about Frame Relay:

- originally designed for use across ISDN interfaces.

- is an example of packet-switched technology

- Uses SVC's and PVC's

2. Which of the following network utilisation percentage figures would indicate that an Ethernet segment is saturated? Choose all that apply...

a. 100%

b. 32%

c. 75%

d. 43%

e. 92%

3. Match the following Scalability Constraints for Flat - Switched and Bridged - Networks with the correct letter: 

a = 200 workstations

b = 300 workstations

c = 400 workstations

d = 500 workstations

e = 100 workstations

Protocol                                                        Max Number of Workstations

IPX

IP

NetBIOS

AppleTalk

Mixed

Scroll down for the multiple choice answers...

Cheers

Hi All

Here is my first attempt for this:

1 Give us 2 things about multicast

- Class D IP Address range (224.0.0.0 - 239.255.255.255)

- IGMP is used to dynamically register the hosts on a subnet

2 NAT, give 2 Traffic Types supported by Cisco IOS

- http

- ntp

3 EIGRP, 3 things to know about it

- Rapid convergence times

- sends partial routing updates instead of full routing tables

- metric = bandwidth + delay

Have fun

Anyone up for reviving the TWQs? There has been some recent interest in 640-441, so I will use some information from that exam for this TWQ. I know that previously we had started TWQs on Tuesday or Wednesday, but I have time to do this now so...

As usual, unless the question is multiple choice, answers must be unique within the group.

1. Tell me three things about BGP.

a. It stands for Border Gateway Protocol

b. It is an interdomain routing protocol

c. It is defined in RFCs 1163, 1267, 1654, 1772, and 1930

2. When characterizing network traffic one of the tough things to figure out is how protocols act in their environment. Broadcast behavior, frame size, windowing and flow control, and error recovery mechanisms are all important aspects of network traffic characterization. Tell me two thing about each of the above areas as they relate to network traffic characterization.

Broadcast behavior: 

1. Broadcasts can cripple a network, so there are scalability constraints to consider. 

2. Layer 2 switches forward broadcasts and multicasts.

Frame size: 

1. Making it as large as possible for the medium can greatly enhance a network. 

2. Making it too large leads to fragmentation.

Windowing and Flow Control: 

1. TCP uses it, UDP doesn't 

2. Some protocols in the TCP/IP stack that support it are FTP, telnet, SMTP, and HTTP.

Error Recovery: 

1. Connectionless protocols usually do not implement error recovery 

2. Connection-oriented protocols include Frame Relay, ATM, and SPX.

3.Tell me one thing about a scalable internetwork.

a. It follows a hierarchical model consisting of a core, distributive, and access layers.
