Users are complaining that the performance of the network is not satisfactory. It takes a long time to pull files from the server, and, under heavy loads, workstations can become disconnected from the server. The network is heavily used, and a new video conferencing application is about to be installed. The network is a 100BaseT system created with Ethernet hubs. Which of the following devices are you most likely to install to alleviate the performance problems?
Switch
Router
Bridge
Gateway
Which of the following devices forwards data packets to all connected ports?
Router
Switch
Bridge
Hub
Of the following routing methods, which is likely to take the most amount of administration time in the long term?
Static
Link state
Distance vector
Dynamic
Your manager asks you to look into some upgrades for your network. The current network is a 10Base2 system, and you have been experiencing numerous hard-to-track-down cable problems. As a result, you have decided to upgrade to a 10BaseT system. On the networking vendor's price list are both active and passive hubs. The passive hubs are considerably cheaper than the active ones, and you are tempted to opt for them so that you come in under budget. A colleague advises you against the purchase of passive hubs. What is the primary difference between an active and a passive hub?
Passive hubs do not offer any management capabilities.
Passive hubs cannot be used in full-duplex mode.
Passive hubs do not regenerate the data signal.
Passive hubs forward data to all ports on the hub, not just the one for which they are intended.
Which of the following statements best describes a gateway?
It is a device that enables data to be routed from one network to another.
It is a term used to refer to any device that resides at the entrance of a network.
It is a device, system, or application that translates data from one format to another.
It is a network device that can forward or block data based on the MAC address embedded within the packet.
You have a thin coaxial-based Ethernet network and are experiencing performance problems on the network. By using a network performance-monitoring tool, you determine that there are a large number of collisions on the network. In an effort to reduce the collisions, you decide to install a network bridge. What kind of bridge are you most likely to implement?
Collision bridge
Transparent bridge
Visible bridge
Translational bridge
Which of the following represents a valid MAC address?
00-D0-56-F2-B5-12
00-63-T6-4H-7U-78
00-62-DE-6F-D2
000-622-DE5-75E-EA6
Which of the following devices passes data based on the MAC address?
Hub
Switch
MSAU
Router
What is the speed of the 16550 UART chip?
921,600
430,800
115,200
9,600
Which of the following devices would you find only on a Token Ring network?
Hub
Switch
MSAU
Router
