Question 1 Refer to the figure below. Which ports will be the root switch, root ports and blocking ports if all the switches are operating at the same priority? SWITCHA 002A.3050.0B07 SWITCH 002A.3050.0BOC F80/2 Fao/s gu/ Fa0/1 Fa0/2 F20/1 GI/ Fa0/1 Fa0/2 Fa0/2 SWITCH 002A.3050.0005 SWITCHD 002A.3050.0025 (3 marks) Semester 1, 2019 Page 3 of 14 FINAL EXAMINATION HIT374 - Enterprise Network Engineering THIS EXAMINATION PAPER AND SUPPLIED MATERIALS ARE NOT PERMITTED TO BE REMOVED FROM ANY EXAMINATION VENUE IN ANY CIRCUMSTANCE. THIS EXAMINATION IS PRINTED DOUBLE SIDED. Question 2 Refer to the figure below. The configuration shows commands entered by a network administrator for inter- VLAN routing. However, host H1 cannot communicate with H2. What could be the problem and what must be done to allow H1 to communicate with H2? R1(config)# interface gi0/0 R1(config-if)# no shutdown R1(config-if)# interface gi0/0.10 Gi0/01 R1(config-subif)# encapsulation dotig 10 R1(config-subif)# ip address 192.168.10.1 255.255.255.0 Gi0/1 R1(config-if)# interface gi0/0.20 R1 (config-subif)# encapsulation dotig 20 S1 R1(config-gubif)# ip address 192.168.20.1 255.255.255.0 Fa0/1 Fa0/2 H1 S1(config)# interface gi0/1 H2 si (config-if)# switchport mode trunk 51(config)# interface fa0/1 VLAN 10 VLAN 20 S1(config-if)# switchport mode access $1(config)# interface fa0/2 $1(config-if)# switchport mode access (2 marks) Question 3 A Layer 2 Ethernet switch with 12 ports, where all ports belong to the same VLAN, has how many collision domains and how many broadcast domains? No. of collision domains: No. of broadcast domains: (1 mark)
