17) you have a subnet mask of 255.255.255.248 what is the Classess InterDomain Routing (CIDR) notation?
Answer: Option d) /29
18) How manysubnets do you get with a subnet of 192.168.1.0/28?
Answer: Option b) 16
19) What are two methods used to prevent loops in a distance vector routing protocol?
Answer: Option D) Split horizon and Hold-down timer
20) What is the purpose of introducing NAT in a network design?
Answer: Option C) C. allows private IP address (RFC 1918) to be translated into Internet routable IP
addresses (public IP addresses)
21) When a wireless channel uses more than one frequency the transmission method called____ spectrum
Answer: Option A) Spread
22) Which of the following is one of the broad categories of wireless antennae that are based on caverage?
Answer: Option D) Unidirectional and E) Omnidirectional
Explanation:
Omnidirectional: An omnidirectional antenna radiates power at relatively equal power levels in all directions .
Unidirectional: Unidirectional antennas can focus their power in a specific direction, thus avoiding potential
interference with other wireless devices and perhaps reaching greater distances than those possible with
omnidirectional antennas. One application for unidirectional antennas is interconnecting two nearby buildings
23) The ______ command displays NetBIOS information in IP based networks
Answer: Option d) nbtstat
Explanation: nbtstat can be use to display NetBIOS over TCP/IP statistics, the current NetBIOS configuration and open connections
24) The _____ command can display a PC's current IP routing table
Answer: Option a) route
Explanation: The "route" command can display a PC's current IP routing table. Additionally, the "route" command can be used to add or delete entries to or from that routing table.
25) Which command is a unix command?
Answer: Option d) ipconfig
Explanation: The ipconfig command is used on Windows, while the ifconfig command is used on Linux, Mac OS X, and other Unix-like operating systems. These commands allow you to configure your network interfaces and view information about them.
26) What is the name of the instrument picture below?
Answer: Option A) Crimper
