What Is The Main Benefit Of Using Rapid Pvst+?

Which two issues are the result of a broadcast storm?

Which two issues are the result of a broadcast storm.

Due to high processing demands during a broadcast storm , communication may fail between end stations in the broadcast domain.

Durining a boardcast storm , constant changes to the MAC address table prevent a switch from accurately forwarding frames..

What is the difference between Bpdu Guard and Root Guard?

BPDU Guard: Prevents accidental connection of switching devices to PortFast-enabled ports. … BPDU filtering: Restricts the switch from sending unnecessary BPDUs out access ports. Root Guard: Prevents switches connected on ports configured as access ports from becoming. the root switch.

What are two advantages of using LACP?

What are two advantages of using LACP? (Choose two.) It eliminates the need for configuring trunk interfaces when deploying VLANs on multiple switches. It decreases the amount of configuration that is needed on a switch. It provides a simulated environment for testing link aggregation.

Which two issues are the result of a broadcast storm choose two group of answer choices?

Which two issues are the result of a broadcast storm? (Choose two.) *During a broadcast storm, a switch will forward a received broadcast out every port on the switch. *Due to high processing demands during a broadcast storm, communication may fail between end stations in the broadcast domain.

What are two drawbacks to turning spanning tree off?

What are two drawbacks to turning spanning tree off and having multiple paths through the Layer 2 switch network? (Choose two.)The switch acts like a hub.Port security becomes unstable.The MAC address table becomes unstable.Broadcast frames are transmitted indefinitely.More items…•

What is difference between Pvst and RSTP?

The RSTP is an improvement on the spanning tree protocol, and it is a standard spanning tree as an IEEE standard while the PVST is a spanning tree protocol as a Cisco proprietary. PVST is the Cisco counterpart of IEEE’s RSTP. PVST is usually used on VLANS (or Virtual Local Area Network) while RSTP is often used in LAN.

What protection does Bpdu Guard provide?

PortFast BPDU guard prevents loops by moving a nontrunking port into an errdisable state when a BPDU is received on that port. When you enable BPDU guard on the switch, spanning tree shuts down PortFast-configured interfaces that receive BPDUs instead of putting them into the spanning tree blocking state.

What is an advantage of using LACP?

It allows directly connected switches to negotiate an EtherChannel link. It eliminates the need for configuring trunk interfaces when deploying VLANs on multiple switches. It decreases the amount of configuration that is needed on a switch.

What are two advantages of EtherChannel?

Configuring the EtherChannel interface provides consistency in the configuration of the physical links. Spanning Tree Protocol ensures redundancy by transitioning failed interfaces in an EtherChannel to a forwarding state. EtherChannel uses upgraded physical links to provide increased bandwidth.

What is an advantage of Pvst+?

What is an advantage of PVST+? PVST+ optimizes performance on the network through load sharing. 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.

What is the best way to prevent a VLAN hopping attack?

What is one way to prevent the VLAN hopping attack? Disable DTP negotiation on all ports. Turn trunking off on all ports that are used to connect to hosts and disable DTP negotiation on all trunking ports to prevent the VLAN hopping attack. This type of attack can be attempted through switch spoofing or double tagging.

What is the purpose of Bpdu guard?

BPDU Guard feature is used to protect the Layer 2 Spanning Tree Protocol (STP) Topology from BPDU related attacks. BPDU Guard feature must be enabled on a port that should never receive a BPDU from its connected device.

What is difference between Bpdu guard and Bpdu filter?

As the name says, BPDU filter filters BPDUs in both directions. BPDU filter will prevent inbound and outbound BPDU but will remove portfast state on a port if a BPDU is received. … On the other hand, BPDU Guard keeps an eye open for any BPDU’s entering the interfaces that are enabled this feature.

What characterizes a floating static route?

Floating static routes are static routes that have an administrative distance greater than the administrative distance of another static route or dynamic routes. They are very useful when providing a backup to a primary link, as shown in Figure 2-66.

How does configuring a port with PortFast allow for faster convergence?

How does configuring a port with PortFast allow for faster convergence? PortFast allows for an access port to immediately transition into a forwarding state which decreases Layer 2 convergence time.
