Which of the following is an outcome of a Layer 2 broadcast storm?
Routers will take over the forwarding of frames
New traffic is discarded by the switch because it is unable to be processed.

VLAN interface
port channel
Your are assigned as the Network Admin of CiT157 Cyberops Corp. For several weeks you had observed there are traffic occurring within the LAN.
You used EtherChannel link between switches SwitchNorth and SwitchSouth by using the command
SW1(config-if-range)# channel-group 1 mode passive.
Which command must be used on SwitchSouth to enable this EtherChannel?
SS(config-if-range)# channel-group 1 mode auto
SS(config-if-range)# channel-group 1 mode active
SS(config-if-range)# channel-group 1 mode passive
SS(config-if-range)# channel-group 1 mode desirable
Which statements are true regarding the use of PAgP to create EtherChannel? Select two.
It requires full duplex
It is Cisco proprietary
It requires more physical links than LACP does
It increases the number of ports that are participating in spanning tree
modes include: active, desirable, auto
What are the IEEE codes for Link Aggregation protocols? Select two.
802.3ad
802.1ax
802.1s
802.11ax
802.3wd
Which statement is true describes a characteristic of EtherChannel?
It can combine up to a maximum of 4 physical links
It can bundle mixed types of 100 Mb/s and 1Gb/s Ethernet links
It consists of multiple parallel links between a switch and a router
It is made by combining multiple physical links that are seen as one link between two switches
What is the most cost-effective method of solving interface congestion that is caused by a high level of traffic between two switches?
increase uplink speed
add more VLANs to reduce broadcast domains
aggregate ports by using EtherChannel
insert a router between the switches
What differentiates LACP with PAgP as link aggregation protocol? Select two.
LACP is faster than PAgP
deploy in a multivendor environment
aggregate ports by using SSH ports
modes are Active and Passive
