CCNA 3 Chapter 3 V4.0 Answers6
Refer to the exhibit. The network administrator has just added VLAN 50 to Switch1 and Switch2 and assigned hosts on the IP addresses of the VLAN in the 10.1.50.0/24 subnet range. Computer A can communicate with computer B, but not with computer C or computer D. What is the most likely cause of this problem?
There is a native VLAN mismatch.The link between Switch1 and Switch2 is up but not trunked.
The router is not properly configured for inter-VLAN routing.
VLAN 50 is not allowed to entering the trunk between Switch1 and Switch2.
Refer to the exhibit. The exhibited configurations do not allow the switches to form a trunk. What is the most likely cause of this problem?
Cisco switches only support the ISLtrunking protocol.
The trunk cannot be negotiated with both ends set to auto.
By default, Switch1 will only allow VLAN 5 across the link.
A common native VLAN should have been configured on the switches.
Refer to the exhibit. Which two conclusions can be drawn regarding the switch that produced the output shown? (Choose two.)
The network administrator configured VLANs1002-1005.
The VLANs are in the active state and are in the process of negotiating configuration parameters.
A FDDI trunk has been configured on this switch.
The command switchport access vlan 20 was entered in interface configuration mode for Fast Ethernet interface 0/1.
Devices attached to ports fa0/5 through fa0/8 cannot communicate with devices attached to ports fa0/9 through fa0/12without the use of a Layer 3 device.
4. What statements describe how hosts on VLANs communicate?
Hosts on different VLANs use VTP to negotiate a trunk.
Hosts on different VLANs communicate through routers.
Hosts on different VLANs should be in the same IP network.
Hosts on different VLANs examine VLAN ID in the frame tagging to determine if the frame for their network.
5. Switch portfa0/1 was manually configured as a trunk, but now it will be used to connect a host to the network. How should the network administrator reconfigure switch port Fa0/1?
Delete any VLANs currently being trunked through port Fa0/1.
Administratively shut down and re-enable the interface to return it to default.
Enter the switchport mode access command in interface configuration mode.6.
Refer to the exhibit. SW1 and SW2 are new switches being installed in the topology shown in the exhibit. Interface Fa0/1 on switch SW1 has been configured with trunk mode “on”. Which statement is true about forming a trunk link between the switches SW1 and SW2?
Interface Fa0/2 on switch SW2 will negotiate to become a trunk link if it supports DTP.
Interface Fa0/2 on switchSW2 can only become a trunk link if statically configured as a trunk.
Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link if the neighboring interface is configured in nonegotiate mode.
Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link automatically with no consideration of the configuration on the neighboring interface.7. The network administrator wants to separate hosts in Building A into two VLANs numbered 20 and 30. Which two statements are true concerning VLAN configuration? (Choose two.)
The VLANs may be named.
VLAN information is saved in the startup configuration.
Non-default VLANs created manually must use the extended range VLAN numbers.
The network administrator may create the VLANs in eitherglobal configuration mode or VLAN database mode.
Both VLANs may be named BUILDING_A to distinguish them from other VLANs in different geographical locations.
8. What is a valid consideration for planning VLAN traffic across multiple switches?
Configuring interswitch connections as trunks will cause all hosts on any VLAN to receive broadcasts from the other VLANs.
A trunk connection is...
