1 switches in the network. How will a broadcast frame that is sent by host PC1 be handled on network? Switch SW1 will block the broadcast and drop the frame. generate an endless loop in the network. the network will replay with a unicast frame sent to host PC1. All hosts in the network will replay with a unicast frame sent to switch SW1. 2 not enabled, what will be the result of this ARP request? Router_1 will drop the broadcast and reply with the MAC address of the next hop router. Switch_A will reply with the MAC address of the Router_1 E0 interface. Switch_A and Switch_B will continuously flood the message onto the network. The message will cycle around the network until its TTL is exceeded. 3 What two elements will exist in a converged network with one spanning tree? (Choose two.) one root bridge per network all non-designated ports forwardin one root port per non-root bridge multiple designated ports per segment one designated port per network 4 Which two criteria does a switch use to select the root bridge? (Choose two.) bridge priority switching speed number of ports base MAC address switch location memory size 5 to negotiate a trunk between switches to set the duplex mode of a redundant link to identify the shortest path to the root bridge to prevent loops by sharing bridging tables between connected switches to determine which ports will forward frames as part of the spanning tree 6 Which two statements describe the BIDs used in a spanning tree topology? (Choose two.) They are sent out by the root bridge only after the inferior BPDUs are sent. They consist of a bridge priority and MAC address. Only the root bridge will send out a BID. They are used by the switches in a spanning tree topo
