BEST NETWORK+ N10-007 STUDY GUIDE 2019 Which of the following physical LAN topologies requires the most cabling? A Star B WLAN C Bus D Ring Answer- A A network formed by interconnect... ing a PC to a digital camera via a USB cable is considered what type of network? A MAN B PAN C CAN D WAN Answer- B Which type of network is based on network clients sharing resources with one another? A Peer-to-peer B Client-peer C Client/Server D Peer-to-server Answer- A Which of the following provides the media (wired or wireless) to facilitate the transfer of data? A Router B Server C LAN D Client Answer- C What network type would help facilitate communications when large video or audio files need to be housed and transferred through the network? A WLAN B CAN C PAN D SAN Answer- D A company has various locations in a city interconnected using Metro Ethernet connections. This is an example of what type of network? A WAN B CAN C PAN D MAN Answer- D How many WAN links are required to create a full mesh of connections between five remote sites? A 20 B 5 C 10 D 15 Hint: Remember, the formula for the number of connections required for the full-mesh topology is n(n-1)/2, where n is the number of nodes. So, in this case, 5(5-1)/2 is 10.

A Better performance B Simplified administration C More scalable D Less expensive Answer- D What type of wireless topology features the use of access points to facilitate network communications? A Mesh B Ad hoc C Ring D Infrastructure Answer- D Which of the following topologies offers the highest level of redundancy? A Hub and spoke B Bus C Partial mesh D Full mesh Answer- D Which device makes traffic-forwarding decisions based on MAC addresses? A Multiplexer B Switch C Router D Hub Answer- C Identify two advantages of a hub-and-spoke WAN topology as compared to a full-mesh WAN topology. 1) More scalable 2) Optimal routes 3) Lower cost 4) More redundancy A 1,2 & 3 B 1 & 3 Answer- B What is the range of well-known TCP and UDP ports? A 16,384-32,768 B Below 1024 C Below 2048 D Above 8192 Answer- B Identify the well-known UDP port number for NTP. A 143 B 123 C 69 D 53 Answer- B IP addresses reside at which layer of the OSI reference model?
