A.VTP updates are ignored and forwarded out all ports.
B.VTP updates are ignored and forwarded out trunks only.
C.VTP updates are made to the VLAN database and are forwarded out trunks only.
D.VTP updates are ignored and are not forwarded.

3.多項(xiàng)選擇題Which two of these are used in the selection of a root bridge in a network utilizing Spanning Tree ProtocolIEEE 802.1 D？（）

A.Designated Root Cost
B.bridge ID priority
C.max age
D.bridge ID MAC address
E.Designated Root Priority
F.forward delay

4.單項(xiàng)選擇題Spanning Tree Protocol IEEE 802.1 s defines the ability to deploy which of these？（）

A.one global STP instance for all VLANs
B.one STP instance for each VLAN
C.one STP instance per set of VLANs

5.單項(xiàng)選擇題Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correctBGP session endpoint addresses and the correct BGP session hop-count limit EBGP multihop. What is agood first test to see if BGP will work across the firewall？（）

A.Attempt to TELNET from the router connected to the inside of the firewall to the router connected to theoutside of the firewall. If telnet works， BGP will work， since telnet and BGP both use TCP to transportdata.
B.Ping from the router connected to the inside interface of the firewall to the router connected to theoutside interface of the firewall. If you can ping between them， BGP should work， since BGP uses IP totransport packets.
C.There is no way to make BGP work across a firewall without special configuration， so there is no simpletest that will show you if BGP will work or not， other than trying to start the peering session.
D.There is no way to make BGP work across a firewall.
