Which protocol provides up to 16 instances of RSTP, combines many VLANs with the same physical and logical topology into a common RSTP instance, and provides support for PortFast, BPDU guard, BPDU filter, root guard, and loop guard?
Which two types of spanning tree protocols can cause suboptimal traffic flows because they assume only one spanning-tree instance for the entire bridged network? (Choose two.)
Image Owner ID is 001e.7aa3.5e71
Refer to the exhibit. Which protocol information is being displayed in the output?
A network administrator is preparing the implementation of Rapid PVST+ on a production network. How are the Rapid PVST+ link types determined on the switch interfaces?
Link types are determined automatically.*
Which RSTP ports are connected to end devices?
If no bridge priority is configured in PVST, which criteria is considered when electing the root bridge?
lowest MAC address*
Which port state will switch ports immediately transition to when configured for PortFast?
To obtain an overview of the spanning tree status of a switched network, a network engineer issues the show spanning-tree command on a switch. Which two items of information will this command display? (Choose two.)
1:The role of the ports in all VLANs.*
2:The root bridge BID.*
Which STP priority configuration would ensure that a switch would always be the root switch?
spanning-tree vlan 10 priority 0*
Which nonproprietary protocol provides router redundancy for a group of routers which support IPv4 LANs?
Fill in the blank.
In FHRP operation, two or more routers are represented as a single " virtual " router.
Which three components are combined to form a bridge ID?
extended system ID*
What is a characteristic of a Layer 2 loop?
Broadcast frames are forwarded back to the sending switch.*
Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.)
1:redundant links between Layer 2 switches*
2:removing single points of failure with multiple Layer 2 switches*
What additional information is contained in the 12-bit extended system ID of a BPDU?
What is an advantage of PVST+?
PVST+ optimizes performance on the network through load sharing.*
What is the purpose of HSRP?
It provides a continuous network connection when a router fails.*
In which two port states does a switch learn MAC addresses and process BPDUs in a PVST network? (Choose two.)
Refer to the exhibit. A network engineer is troubleshooting host connectivity on a LAN that uses a first hop redundancy protocol. Which IPv4 gateway address should be configured on the host?
What is the outcome of a Layer 2 broadcast storm?
New traffic is discarded by the switch because it is unable to be processed.*
