Q:

You are the network administrator and are given the tasks to plan for the future expansion of the network. You decide to subnet the current network of 172.15.0.0. What will be the subnet mask be if every subnet has to allocate 500 hosts.

A) 255.255.0.0 B) 255.0.0.0
C) 255.255.240.0 D) 255.255.254.0
 
Answer & Explanation Answer: D) 255.255.254.0

Explanation:

Explanation: The requirement of having to allocate 500 hosts on each subnet can be achieved by the following: 2^9 = 512. So deducting the broadcast and network address we have 510 possible hosts on each subnet. We used 9 bits to allocate the hosts, this leaves us 7 bits for possible subnets. Those 7 bits in binary is 1111 1110 or 254 in decimal.

Q:

We want to assign port 3 of our Catalyst 2950 switch to VLAN 3. What command will achieve this?

A) switch(config-if)#switchport vlan 3 B) switch#switchport access vlan 3
C) switch(config)#switchport access vlan 3 D) switch(config-if)#switchport access vlan 3
 
Answer & Explanation Answer: D) switch(config-if)#switchport access vlan 3

Explanation:

Explanation: The switchport access vlan [number] command will configure a switch port to that VLAN. You can also use the switchport access vlan dynamic command to configure the switch port automatically in a certain VLAN depending on the VLAN membership of the incoming packets. For both commands to work properly the switch port needs to be in access mode

Q:

Why is BGP a better choice for Internet routing than the IGPs?

Answer

RIP version 1 and IGRP are classful protocols and do not advertise subnet mask information. RIP version 2 has a limited network diameter of 15 hops. EIGRP, OSPF, and IS-IS use computational intensive algorithms for determining a shortest path. BGP relies on simple techniques for best path selection and loop detection, and can handle the number of network prefixes required for Internet routing.

Q:

Explain the difference between the forwarding of a unicast IP packet and the forwarding of a multicast IP packet.

Answer

Unicast IP packets are forwarded based on the destination IP address. Multicast packets are forward based on the source IP address. If a multicast packet is received on the interface used to send a unicast packet back to the source, the multicast packet is forwarded to multicast neighbors. If the multicast packet is received on an interface that would not be used to send a unicast IP packet back to the source, the packet is discarded.

Q:

What is the purpose of the LOCAL_PREF attribute?

Answer

If a router has more than one route to the same IP prefix, the best path is the one with the highest LOCAL_PREF (assuming the WEIGHT attribute for the routes is equal).

Q:

What is the purpose of the AS_PATH attribute?

Answer

If a router has more than one route to the same IP prefix, the best path is the one with the shortest AS_PATH (assuming other BGP attributes are equal).

Q:

What is the difference between the types of routes allowed by default into IS-IS and OSPF areas?

Answer

By default, all routes are advertised into all OSPF areas. This includes interarea OSPF routes and external routes that have been injected into OSPF. By default, IS-IS does not advertise interarea or external routes into an area, but injects a default route.
