Exam 7: Physical and Network Topology Security

Which type of network device provides immediate battery power to equipment during a power failure or brownout?

What four different network topologies are in use in networks today?

____________________ is the transmission capacity of a communications medium, which is typically measured in bits per second (for data communications) or in hertz (for data voice and video communications), and is determined by the maximum minus the minimum transmission capacity.

Which type of network device connects two or more cable segments and retransmits any incoming signal to all other segments?

In Netware 6.x after you use the SECURE CONSOLE command, you cannot disable it without rebooting the server.

Twisted-pair cabling is more flexible than coax cable and therefore better for running through walls and around corners.

Does physical security further involve the location of computers and network devices in a building, along with the construction quality of that building?

Which type of network device links network segments and forwards and filters frames between segments?

What is the biggest disadvantage of shielded twisted-pair cabling?

It is more difficult with a(n) star topology than with the traditional bus topology for someone to create an unauthorized tap into the network, because they need access to the central hub or switch.

____________________ is a protocol in the TCP/IP suite that enables computers and network equipment to gather standardized data about network activity.

_________________________ refers to installing cable that fans out in a horizontal star fashion from one or more centralized hubs or switches, which are located in telecommunications rooms or wiring closets.

When working with twisted-pair cabling, solid shielding is used for indoor wiring, and corrugated shielding is used for outside or underground wiring.

Which operating system uses XScreenSaver to lock the screen?

List eight different network devices.

Is it easy for someone to place unauthorized taps into fiber-optic cable?

In a(n) ____________________ server security model, the physical security used for servers may vary widely from server to server and department to department.

What is one of the disadvantages of a ring network?

The physical side of the network is how the signal is transferred from point to point along the cable.

In Red Hat Linux 9.x, is SNMP typically installed during the initial installation of the operating system on TCP/IP servers?
