Which troubleshooting tool can you use to replicate traffic within a single switch for analysis?
정답: A
Which WAN topology is most appropriate for a centrally located server farm with several satellite branches?
정답: D
Scenario:
You work as Junior Network Engineer for RADO Network Ltd company. Your colleague has set up a Layer 2 network for testing purpose in one of your client locations. You must verify the configuration and fix if any issues identified as per customer requirements.
Topology Details
- Three switches (SVV1. SW2, and SW3) are connected using Ethernet link as shown in the topology diagram.
- Server1 and PC1 are connected to SW1 and are assigned to VLAN 500 and VLAN 600 respectively.
- Server2 and PC2 are connected to SW2 and are assigned to VLAN 500 and VLAN 600 respectively.
- PC3 is connected to SW3 and assigned to VLAN 600.
Customer requirements
- Verify if switch ports are assigned in correct VLANs as per topology
diagram Identify and fix any misconfigurations found in three switches.
- Verify if trunk links are operational between switches and the IEEE
802.1 q trunk encapsulation method is used Identrfy and fix if any
misconfigurations are found in the trunk configuration
- You must make sure the ports connected between switches are set as
trunk ports.
Special Note: To gain the maximum number you must make sure that VLANs are assigned to switch ports as per customer requirements and make sure the trunk links are operational between switches Do not change VLAN names and VLAN number that are already configured in the switches

정답:
Switch 1 port E0/1 WAS CONNECTED TO A COMPUTER WITH A STRAIGHT THROUGH
CABLE AND AS WELL AS ROLLOVER CABLE (FOR CONFIGURATION OF SWITCH
PORTS ON THIS SWITCH) WHICH WAS SHOWN IN VLAN 600 IN THE DIAGRAM BUT
ACTUALLY THAT PC WAS NOT IN VLAN 600 AFTER CHECKING THE VLAN
CONFIGURATION USING SHOW VLAN COMMAND. INSTEAD THIS PORT WAS
CONFIGURED IN VLAN 1. SO WE NEEDED TO PUT THAT PC IN VAN 600 USING
FOLLOWING COMMANDS:
SW1(CONFIG)# INTERFACE E0/0
SW1(CONFIGIF)#
SWITCHPORT MODE ACCESS
SW1(CONFIG-IF)#SWITCHPORT ACCESS VLAN 600
NOW THE E0/0-PORT OF THIS SWITCH-SW1 WAS RECEIVING NATIVE VLAN
MISMATCH FROM SW3 SWITCH-PORT E0/1. ALSO E0/0 OF SW1 AND E0/1 OF SW3
WERE NOT IN TRUNKING MODE. AND THE QUESTION WAS ASKED TO MAKE SURE
THAT CONNECTION BETWEEN BOTH SWITCHES SHOULD BE IN TRUNKING MODE
WITH 802.1Q ENCAPSULATION ENABLED SO USED THE BELOW COMMANDS:
SW1(CONFIG)#INT E0/0
SW1(CONFIG-IF)#SWITCHPORT TRUNK ENCAPSULATIONDOT1Q
SW1(CONFIG-IF)# SWITCHPORT MODE TRUNK.
ON OTHER SWITCH WHICH IS SWITCH3
SW3(CONFIG)#INT E0/0
SW3(CONFIG-IF)#SWITCHPORT TRUNK ENCAPSULATIONDOT1Q
SW3(CONFIG-IF)# SWITCHPORT MODE TRUNK.
SW3(CONFIG-IF)#
SWITCHPORT TRUNK NATIVE VLAN 1
ALSO PORT E0/2 OF SW3 WAS CONNECTED TO SERVER AND IN VLAN 600 AND
PORT E0/3 WAS ASSIGNED TO VLAN 500 AND TO A COMPUTER AGAIN IN VLAN 500
ITSELF. SO THAT COMPUTER HAD A CONSOLE CABLE CONNECTED TO SW3 AS
WELL IN ORDER TO CONFIGURE SW3 PORTS AS TRUNK PORTS AND
SWITCHPORTS USING THE ABOVE STEPS FOR SW1 WHICH WAS MENTIONED
ABOVE.
SIMILARLY SW2 PORT E0/1 PORT WAS CONNECTED TO E0/4 PORT OF SW3 SO
AGAIN TRUNK LINK CONFIGURATIONS BETWEEN E0/1 AND E0/4 PORTS BETWEEN
TWO SWITCHES NEED TO EB DONE HERE. BUT YOU NEDD NOT TO AGAIN RUN
THAT NATIVE VLAN COMMAND CHANGE ON SW3 OR SW2 SINCE ON SW3 WE
AKREADY CHANGED IN ABOVE STEP AND IN SW2 ITS FINE IN VLAN 1 ONLY.
A COMPUTER WAS CONNECTED TO PORT E0/2 OF SW2 AND WAS IN VLAN 600
AND E0/3 WAS CONNECTED TIO SERVER WHCH WAS IN VLAN 600 AGAIN. ALSO
AGAIN THIS TIME THE COMPUTER WAS CONNECTED TO THE SWITCH USING A
CONSOLE CABLE ASWELL TO GIVE YOU CONSOLE ACCESS TO CONFIGURE AND
VERIFY THE CONFIGURATIONS ON SW2. SO JUST VERIFY THE ACCESS PORTS
ARE CORRECTLY ASSIGNED AND TRUNK PORTS AS WELL USING BELOW
COMMANDS.
