What else can I help you with?
Which process best describes selective forwarding a switch?
forwarding packets to the port that is connected to the destination node
What address type does a switch use to make selective forwarding decisions?
destination mac address
What is a Process switch?
In process switching the CPU is required to be personally involve with every forwarding decision. Process switching is similar to doing long math versus doing it the quick way.
When a switch port is recovering from a failure which protocol allows it to transition to forwarding state?
When a switch port is recovering from a failure, the Spanning Tree Protocol (STP) allows it to transition to the forwarding state. STP helps prevent loops in network topologies by managing the state of switch ports, including listening, learning, and forwarding states. During recovery, the port goes through a series of state changes, ensuring it only transitions to forwarding when it is safe to do so. This process helps maintain network stability and integrity.
What switch mode offers minimum latency?
Cef (cisco express forwarding)
What is a mechanism that is used on Cisco Layer 3 switches to accelerate forwarding of Layer 3 packets?
Cisco Express Forwarding accelerates forwarding of packets on a Cisco Layer 3 switch by associating a MAC address with a next hop address in the FIB.
Which protocol is used by a switch to prevent forwarding loops in networks containing redundant paths?
STP
How does a switch use store and forward?
In store-and-forward switching, the switch receives an entire data frame before forwarding it to the next hop in the network. This allows the switch to perform error checking on the entire frame before forwarding it, ensuring data integrity. The switch stores the frame temporarily in its memory, checks for errors, and then forwards it based on its destination address.
What is accurate about fast-forward switching?
The switch stores the first 64 bytes of the frame before forwarding.
Whart are the switch and bridge port characteristic of a layer two spaming-tree network that is fullycoverged?
a. All switch and bridge ports are in the forwarding state. b. All lkswitch and bridge ports are in the stand by state. c. All switch and bridge parts are assigned as either root or designed. d. All switch and bridge ports are in either the forwarding or blocking state. e. All switch and bridge are either blocking or looping.
Which layer of the OSI model does an access layer LAN switch use to make a forwarding decision?
Layer 2.
When the show spanning-tree vlan 33 command is issued on a switch three ports are shown in the forwarding state In which two port roles could these interfaces function while in the forwarding state?
designated and root
