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 process best describes selective forwarding in a switch?
forwarding packets to the port that is connected to the destination node
Which process best describes selective forwarding a switch?
forwarding packets to the port that is connected to the destination node
How is blocking related to a crossbar switch?
: Blocking can occur when two switch inputs attempt to access the same intermediate switch channel.
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
What address type does a switch use to make selective forwarding decisions?
destination mac address
What is accurate about fast-forward switching?
The switch stores the first 64 bytes of the frame before forwarding.
What is a non blocking switch fabric?
is when all the switched ports have connections to the switch fabric equal to their line speed
What is a non-blocking switch fabric?
is when all the switched ports have connections to the switch fabric equal to their line speed
Which layer of the OSI model does an access layer LAN switch use to make a forwarding decision?
Layer 2.
