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 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.
What is native VLAN?
native vlan means that device will never put/insert tag (VLAN ID, in you case “VLAN ID:2”) on Ethernet frame when it leaves port and also when Ethernet frame without tag go into that port device will put/insert tag defined by native vlan ( in you case VLAN ID:2).
What is Rapid Spanning Tree Protocol?
Rapid Spanning Tree Protocol (RSTP) is a network protocol that ensures a loop-free topology for Ethernet networks. Nowadays it is a popular solution to implement redundant networks in critical systems for Energy, Aerospace or Factory Automation. This protocol is incorporated into IEEE 802.1Q-2014.
What is STP instance?
The 802.1Q standard defines one unique Spanning-Tree instance to be used by all VLANs in the network. STP runs on the Native VLAN so that it can communicate with both 802.1Q and non-802.1Q compatible switches. This single instance of STP is also referred to as 802.1Q Mono Spanning Tree or Common Spanning Tree (CST).
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 is the difference between PVST+ and rapid PVST+?
Both RSTP and PVST are variants of the spanning tree protocol. “RSTP” stands for “Rapid Spanning Tree Protocol” while “PVST” does the same for “Per-VLAN Spanning Tree.” RSTP is an improvement of STP (Spanning Tree Protocol) in terms of being newer and faster. …
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.
When would you configure VTP on a switch?
When would you configure VTP on a switch? When you have multiple switches with multiple VLANs and you want to share the VLAN database from one switch to all the others. Which of the following features of a switch will allow two switches to pass VLAN network information?
Is Spanning Tree Protocol still used?
The Spanning Tree Protocol (STP) is widely used for network redundancy and resilience in Ethernet networks, in spite of its well-known flaws and limitations. … I will present the information again in Building the Physical Network for the Software-Defined Data Center on Sept.
What is STP and its types?
Root bridge is a switch in a single VLAN or whole topology (according to the type of STP standard used) which is responsible for distributing BPDUs and block the least redundant port. …
What is the benefit of Pvst+?
PVST+ allows the root switch location to be optimized per VLAN. D. PVST+ automatically selects the root bridge location, to provide optimized bandwidth usage. Per VLAN Spanning Tree (PVST) maintains a spanning tree instance for each VLAN configured in the network.
What is the purpose of the Spanning Tree Protocol STP )?
The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.
Are VLANs more secure?
Because VLANs support a logical grouping of network devices, they reduce broadcast traffic and allow more control in implementing security policies. Also, surveillance traffic is only available to those authorized, and bandwidth is always available, when needed.
What is rapid Pvst+?
Rapid per VLAN Spanning Tree (Rapid PVST+) is an updated implementation of STP that allows you to create one spanning tree topology for each VLAN. Rapid PVST+ is the default Spanning Tree Protocol (STP) mode on the switch. Note. Spanning tree is used to refer to IEEE 802.1w and IEEE 802.1s.
Is Rstp compatible with Pvst+?
PowerConnect spanning-tree mode RSTP is not functioning properly with Cisco switches using spanning-tree mode PVST+. Solution: On 802.1Q trunk links connecting PowerConnect switches to Cisco switches VLAN 1 must be added on both sides regardless of the native VLAN configured.

What is switch spoofing attack?
Switch spoofing is a type of VLAN hopping attack that works by taking advantage of an incorrectly configured trunk port. By default, trunk ports have access to all VLANs and pass traffic for multiple VLANs across the same physical link, generally between switches.
What is the difference between Pvst and Pvst+?
Per VLAN Spanning Tree (PVST) is a Cisco proprietary protocol that allows a Cisco device to have multiple spanning trees. … PVST+ is an extension of PVST that allows a Cisco device to also interoperate with devices that are running a single spanning tree (IEEE 802.1Q).
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 difference between STP and RSTP?
The main difference between Rapid Spanning Tree Protocol (RSTP IEEE 802.1W) and Spanning Tree Protocol (STP IEEE 802.1D) is that Rapid Spanning Tree Protocol (RSTP IEEE 802.1W) assumes the three Spanning Tree Protocol (STP) ports states Listening, Blocking, and Disabled are same (these states do not forward Ethernet …
