What utilities could you use to force the NIC on your Linux server to use full-duplex transmission?
What is a significant advantage to using an SFP interface on a router rather than an on-board NIC?
You and your friend decide to set up Fast Ethernet networks in your respective houses to connect a half-dozen computers at each location. Both of you will connect your networks to high-speed Internet connections. As the connectivity device for end nodes, you purchase a router, whereas your friend uses an old, but functional, 12-port hub he found at a garage sale. What will your network do that your friend's network won't do?
Filter traffic based on IP address.
You are a network technician working on a 100Base-T network. A coworker has been having trouble logging on to the server and asks whether you can quickly tell her if her workstation's NIC is operating properly. You do not have the NIC's utility on hand, but you look at the back of her workstation and learn that although the NIC is properly installed and connected to the network, something's wrong with it. What might you have seen that causes you to come to this conclusion?
None of the LEDs are lit.
How do bridges keep track of whether they should forward or filter frames?
They maintain a filtering database that identifies which frames can be filtered and which should be forwarded, based on their destination MAC address.
You are asked to configure a backbone switch that connects servers supplying oceanic and atmospheric data to mariners and pilots around the world. Your network's traffic load is very high at all times, day and night. What type of switching do you configure the switch to use?
Suppose your company's network contains two separate VLANs. Computer A is on the Customer Service VLAN and computer B is on the Warehouse VLAN. Besides a Layer 2 switch, what device is required for computer A and computer B to exchange data?
In STP (Spanning Tree Protocol), what device acts as a guide to setting the best paths between switches?
What switching technique allows you to funnel traffic belonging to more than one VLAN through a single switch interface?
What types of routing protocols allows routers to exchange information about best paths with their neighboring routers only?
Why is a large, busy network more likely to use dynamic routing?
Because dynamic routing automatically selects the most efficient route between nodes, reducing the possibility of human error.
A packet on a network using RIP (Routing Information Protocol) routing method has been passed from one connectivity device to another 15 times. What happens when it gets passed to one more device?
It is discarded.
What factors is NOT considered when OSPF (Open Shortest Path First) determines the best path for a packet?
?? - (Check Answer) - Number of hops.
What is a router's convergence time?
The time it takes for a router to recognize a best path in the event of a change or network outage.
