Question15:

Which two options are two results of using the command spanning-tree vlan 50 root primary within

a spanning-tree network under global configuration (Choose two):

A) The switchport that is configured for VLAN 50 is the primary connection to the spanning-tree

root switch

B)The primary value for VLAN 50 is set to 4094 on the root while the local switch priority is set to

32768

C) All ports that are configured on the current switch with VLAN 50 transition to designated ports

local switch to lower value

E) The spanning-tree timers are reduced to improve the convergences time for Vlan 50

Answer :C,D

– C) All ports that are configured on the current switch with VLAN 50 transition to designated ports

(because Root switch has only designated ports)

1 Po1(SU) LACP Fa0/1(P), Fa0/2(P)

Switch2# sh etherchannel summary

Number of channel-groups in use: 1

Number of aggregators: 1

Group Port-channel Protocol Ports

1 Po1(SU) Fa0/1(P)

A. Sticky address are still in configuration

B. Sticky address are not in configuration

C. Sticky address can be unicast or multicast address

D. don’t remember

Answer: A. Sticky address are still in configuration (If you enable the sticky method, the device

secures MAC addresses in the same manner as dynamic address learning. These addresses can be

made persistent through a reboot by copying the running-configuration to the startup-

configuration, copy run start.)

Question20:

D It can cause a network-wide configuration change if revision number on the new switch is lower

Answer: C: It can cause a network-wide configuration change if revision number on the new

switch is higher
