|
How can you tell the ethernet frame has a 802.1Q tag?
|
TPID shows 0x8100 (Which defines it as a 802.1Q Tag) along with TCI information...
|
|
|
Default Bridge ID in Spanning Tree?
|
32768 (VLAN1 is 32769 etc..)
|
|
|
In the Spanning Tree root bridge election process, what happens if the priority in the Bridge ID ties?
|
They will then compare MAC addresses and use the lowest MAC address.
|
|
|
Easiest way to choose what switch is elected as the Root Bridge in Spanning Tree for VLAN 10?
|
(config)#spanning-tree vlan 10 root primary
|
|
|
What is the first thing you would typically configure when creating a GRE tunnel?
|
(config)#interface tunnel 1 - (or any other number)
|
|
|
Most preferred authentication protocol when using PPP or PPPoE
|
CHAP (Challenge Handshake Authentication Protocol)
|
|
|
Does a GRE tunnel provide encryption?
|
No, a GRE tunnel is commonly used inside a IPSec tunnel for encryption
|
|
|
Which RFC defines private IP addresses?
|
RFC 1918
|
|
|
How many bytes in a 802.1Q header?
|
4 Bytes (32 bits)
|
|
|
What is route poisoning?
|
When a subnet is unreachable, it will broadcast an update with an infinite metric to advertise that the subnet is unreachable
|
|
|
What port type/number does RIPv1 & v2 use?
|
UDP 520
|
|
|
I can't configure a VLAN on my switch in a VTP domain, what could be a common cause?
|
The VTP mode for the switch is most probably configured with 'vtp mode client'
|
|
|
How do I delete the VTP information for a switch?
|
VTP information is stored in the 'vlan.dat' file. Deleting this would be the answer.
|
|
|
How can I stop routing updates on a specific interface?
|

|
|
|
What port states in STP are classed as 'Stable'?
|
Blocking, Discarding and Forwarding

|
Why does Rapid-STP have better a quicker convergence than PVST+?
|
Listening and Learning states are not in Rapid-STP. This gets rid of the 15 + 15 seconds delay....

|
4
|
|
|
What are the OSPF multicast addresses?

|
That specific router will take over as the active router.
|
|
|

|
No, they need to be configured with the same version to work
