2. two

3. six

4. twelve

Answer: A

Question No: 73 – (Topic 2)

Refer to the exhibit.

A network administrator is configuring an EtherChannel between SW1 and SW2. The SW1 configuration is shown. What is the correct configuration for SW2?

1. interface FastEthernet 0/1 channel-group 1 mode active switchport trunk encapsulation dot1q switchport mode trunk

   interface FastEthernet 0/2 channel-group 1 mode active

   switchport trunk encapsulation dot1q switchport mode trunk

2. interface FastEthernet 0/1 channel-group 2 mode auto switchport trunk encapsulation dot1q

   switchport mode trunk interface FastEthernet 0/2 channel-group 2 mode auto

   switchport trunk encapsulation dot1q switchport mode trunk

3. interface FastEthernet 0/1 channel-group 1 mode desirable switchport trunk encapsulation dot1q switchport mode trunk

   interface FastEthernet 0/2 channel-group 1 mode desirable

   switchport trunk encapsulation dot1q switchport mode trunk

4. interface FastEthernet 0/1 channel-group 1 mode passive switchport trunk encapsulation dot1q switchport mode trunk

interface FastEthernet 0/2 channel-group 1 mode passive

switchport trunk encapsulation dot1q switchport mode trunk

Answer: C

Question No: 74 – (Topic 2)

VLAN 3 is not yet configured on your switch. What happens if you set the switchport access vlan 3 command in interface configuration mode?

1. The command is rejected.

2. The port turns amber.

3. The command is accepted and the respective VLAN is added to vlan.dat.

4. The command is accepted and you must configure the VLAN manually.

Answer: C

Question No: 75 – (Topic 2)

Refer to the exhibit.

Switch-1 needs to send data to a host with a MAC address of 00b0.d056.efa4. What will Switch-1 do with this data?

1. Switch-1 will drop the data because it does not have an entry for that MAC address.

2. Switch-1 will flood the data out all of its ports except the port from which the data originated.

3. Switch-1 will send an ARP request out all its ports except the port from which the data originated.

4. Switch-1 will forward the data to its default gateway.

Answer: B

Question No: 76 – (Topic 2)

Refer to the exhibit.

The network administrator normally establishes a Telnet session with the switch from host

A. However, host A is unavailable. The administrator#39;s attempt to telnet to the switch from host B fails, but pings to the other two hosts are successful. What is the issue?

1. Host B and the switch need to be in the same subnet.

2. The switch interface connected to the router is down.

3. Host B needs to be assigned an IP address in VLAN 1.

4. The switch needs an appropriate default gateway assigned.

5. The switch interfaces need the appropriate IP addresses assigned.

Answer: D

Question No: 77 – (Topic 2)

What are three benefits of implementing VLANs? (Choose three.)

1. A higher level of network security can be reached by separating sensitive data traffic from other network traffic.

2. A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure.

3. A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.

4. Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size.

5. Broadcast storms can be mitigated by decreasing the number of broadcast domains, thus increasing their size.

6. VLANs make it easier for IT staff to configure new logical groups, because the VLANs all

   belong to the same broadcast domain.

7. Port-based VLANs increase switch-port use efficiency, thanks to 802.1Q trunks.

Answer: A,C,D

Question No: 78 – (Topic 2)

Which three statements about RSTP are true? (Choose three.)

1. RSTP significantly reduces topology reconverging time after a link failure.

2. RSTP expands the STP port roles by adding the alternate and backup roles.

3. RSTP port states are blocking, discarding, learning, or forwarding.

4. RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.

5. RSTP also uses the STP proposal-agreement sequence.

6. RSTP uses the same timer-based process as STP on point-to-point links.

Answer: A,B,D

Question No: 79 – (Topic 2)

Which port state is introduced by Rapid-PVST?

1. learning

2. listening

3. discarding

4. forwarding

Answer: C

Question No: 80 – (Topic 2)

What value is primarily used to determine which port becomes the root port on each nonroot switch in a spanning-tree topology?

1. path cost

2. lowest port MAC address

3. VTP revision number

4. highest port priority number

5. port priority number and MAC address
