Computer Networking You have two switches connected together with two crossover cables for redundancy, and STP is disabled. Which of the following will happen between the switches? The switches will automatically load-balance between the two links. The MAC forward/filter table will not update on the switch. Broadcast storms will occur on the switched network. The routing tables on the switches will not update. The switches will automatically load-balance between the two links. The MAC forward/filter table will not update on the switch.

Computer Networking You have been contracted to install a windows NT network in an office that is located in a strip mall. The office is located next to the power plant of the building, so a UPS (uninterruptible power supply) has already been installed. What type of cable should you use for the network cabling? Choose the best answer. UTP Fiber-optic STP PSTN TI UTP Fiber-optic STP PSTN TI ANSWER DOWNLOAD EXAMIANS APP
Computer Networking The Token-Ring architecture was developed for a more efficient way to determine who should be transmitting at any one time. With Ethernet, collisions may take place, causing the transmitting computers to have to retransmit their data. The use of token guarantees that only one computer can transmit at a time. What happens as the network increases in size? Choose the best answer After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device The network becomes more efficient An additional token is added for every 1,000 nodes The network becomes less efficient The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device The network becomes more efficient An additional token is added for every 1,000 nodes The network becomes less efficient The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 ANSWER DOWNLOAD EXAMIANS APP
