Answer: D

IEEE 8021.d Spanning Tree Protocol (STP) was developed to
prevent

routing loops in a network. If a router, switch, or hub has
more then

one path to the same destination, a routing problem could
occur. To

prevent this, the Spanning Tree Protocol is executed between
the devices

to detect and logically block redundant paths from the
network. The main

function of the Spanning Tree Protocol is to allow redundant
network

paths without suffering the effects of loops in the network.

The Spanning Tree Algorithm (STA) implemented by STP
prevents loops by

calculating a stable Spanning Tree network topology. When
creating fault

tolerant internetworks, a loop-free path must exist between
all Ethernet

nodes in the network. Spanning Tree frames called Bridge
Protocol Data

Units (BPDUs) are sent and received by all switches in the
network at

regular intervals.

HI friends mine one of the friends have ask a good question i also donot know the answer so i am putting here Please poet the answer no matter it is wright or wrong put yours view here The question is like that when we are going to configure ospf then there are three way 1st way router ospf 10 netwrok 192.168.1.0 0.0.0.255 area 0 network 192.168.2.0 0.0.0.255 area 0 the 2nd way is like that router ospf 10 netwrok 192.168.0.0 0.0.255.255 area 0 but he inrodused the thrird way like router ospf 10 netwrok 192.168.00000001.0 < ?.?.?.?>area 0 router ospf 10 netwrok 192.168.00000010 <?.?.?.?>area 0 now problem is that what should i put the mask in this way so i puted ? sign Please solve this problem i think this is good one plz donot see for answer please contribute any thing i am reqesting Than you Jitendera kuamr sinha

How does the cut-through switching technique work? A.) By using broadcast address as source addresses B.) The switch waits only for the header to be received before it checks the destination address and starts forwarding the packets C.) The LAN switch copies the entire frame into its onboard buffers and then looks up the destination address in its forwarding, or switching, table and determines the outgoing interface D.) By using a Class I repeater in a collision domain
