|
Which two issues are the result of a broadcast storm? (Choose two.)
|
Due to high processing demands, communication may fail between end stations in the broadcast domain
Constant changes to the MAC address table prevent a switch from accurately forwarding frames |
|
|
When PVST is running over a switched network, which port state can participate in BPDU frame forwarding based on BPDUs received, but does not forward data frames?
|
listening
|
|
|
What is one way to correct a spanning tree failure?
|
Manually remove redundant links in the switched network.
|
|
|
During the implementation of Spanning Tree Protocol, all switches are rebooted by the network administrator. What is the first step of the spanning-tree election process?
|
All the switches send out BPDUs advertising themselves as the root bridge.
|
|
|
Which three port states are used by Rapid PVST+?
|
Discarding
Learning Forwarding |
|
|
Designing a network to use multiple paths between switches to ensure there is no single point of failure
|
Redundancy
|
|
|
Used within a group of routers for selecting an active device and a standby device to provide gateway services to a LAN.
|
HSRP
|
|
|
A Cisco enhancement of RSTP to provide a separate spanning-tree instance for each VLAN
|
Rapid PVST+
|
|
|
The legacy standard for STP that runs all VLANs in a single spanning-tree instance
|
STP
|
|
|
A protocol that allows multiple VLANs to run in a single spanning-tree instance
|
MSTP
|
|
|
An administrator is troubleshooting a switch and wants to verify if it is a root bridge. What command can be used to do this?
|
show spanning-tree
|
|
|
A network administrator is overseeing the implementation of first hop redundancy protocols. Which two protocols will not be able to function with multivendor devices?
|
HSRP
GLBP |
|
|
Which two statements describe a switch port that is configured with PortFast? (Choose two.)
|
The switch port immediately transitions from blocking to the forwarding state.
The switch port should never receive BPDUs. |
|
|
When first hop redundancy protocols are used, which two items will be shared by a set of routers that are presenting the illusion of being a single router? (Choose two.)
|
IP address
MAC address |
|
|
After the election of the root bridge has been completed, how will switches find the best paths to the root bridge?
|
Each switch will analyze the sum of all port costs to reach the root and use the path with the lowest cost.
