Networking Basics Quiz

Name the characteristics of normal range VLANs (Choose three):

• a. IDs 1002 through 1005 are reserved for legacy network technologies (i.e., Token Ring and Fiber Distributed Data Interface)

• e. They are identified by a VLAN ID between 1 and 1005

• d. They support fewer VLAN features than normal range VLANs

• b. IDs 1 and 1002 to 1005 are automatically created and cannot be removed

• c. Configurations are saved, by default, in the running configuration

What are the three routing options between VLANs?

• Legacy Inter-VLAN routing

• Layer 3 switch using switched virtual interfaces (SVIs)

• Point-to point connection

• Router-on-a-Stick

• Hardware routing

On a cisco switch, where is extended VLAN information stored?

• Startup configuration file

• Running configuration file

• Flash

• NVRAM

The max age is the maximum length of time that a switch waits before attempting to change the STP topology. The default is _ seconds

Choose the STP versions

• RSTP

• Slow STP

• PPPSTP

• PVST+

STP is a Layer 3 loop prevention protocol for IP networks.

• True

• False

Although switch ports have a default port cost associated with them, the port cost is configurable. The ability to configure individual port costs gives the administrator the flexibility to manually control the spanning tree paths to the root bridge.

• False

• True

Choose common EtherChannel issues

• If the allowed range of VLANs is not the same, the ports do not form an EtherChannel even when PAgP is set to the auto or desirable mode.

• Trunking was configured on some of the ports that make up the EtherChannel, but not all of them. It is not recommended that you configure trunking mode on individual ports that make up the EtherChannel. When configuring a trunk on an EtherChannel, verify the trunking mode on the EtherChannel.

• Most configuration tasks can be done on the EtherChannel interface instead of on each individual port, ensuring configuration consistency throughout the links.

• Assigned ports in the EtherChannel are not part of the same VLAN, or not configured as trunks. Ports with different native VLANs cannot form an EtherChannel.

Choose the following guidelines and restrictions are useful for configuring EtherChannel:

• VLAN missmatch - All interfaces in the EtherChannel bundle must be assigned to the different VLAN.

• EtherChannel support - All Ethernet interfaces must support EtherChannel with no requirement that interfaces be physically contiguous.

• VLAN match - All interfaces in the EtherChannel bundle must be assigned to the same VLAN or be configured as a trunk (shown in the figure).

Which two DHCPv4 messages are used in the lease renewal process? (Choose two.)

• DHCPRELAY

• DHCPREQUEST
