B. Hub
C. Extender
D. Router
225 You need to replace a faulty 250-foot section of RG-6 cable, but all you have available is RG-59. Which of the following statements is true?
A. The replacement cable will not work because the distance exceeds RG-59 specifications.
B. The replacement cable will not work because RG-6 and RG-59 use different connectors.
C. The replacement cable will not work because RG-6 and RG-59 have different impedance.
D. The replacement cable should work.

228 Which of the following IPv6 addresses is equivalent to 127.0.0.1 in IPv4?
A. ::0
B. ::1
C. ::127
D. 2000::/3
C. The connector shown is a type of mini form factor (MFF) fiber-optic connector called a local connector (LC). It’s especially popular for use with Fibre-Channel adapters, fast storage area networks, and Gigabit Ethernet adapters.
A. The File Transfer Protocol (FTP) is optimized for downloading files from servers. It uses port 21.
D. The Lightweight Directory Access Protocol (LDAP) is a directory services protocol based on the X.500 standard. LDAP is designed to access information stored in an information directory typically known as an LDAP directory or LDAP database. This often includes employee phone numbers and email addresses.
B. The default subnet mask for class B networks is 255.255.0.0, or written in shorthand, /16.
D. If you’re working on a larger network installation, you might use a punchdown tool. It’s not a testing tool but one that allows you to connect (that is, punch down) the exposed ends of a wire into wiring harnesses, such as a 110 block.
C. Fiber-optic broadband Internet offers fast speeds (often in the 1Gbps range) but is also the most expensive.
A. The correct order for a T568B cable is white/orange, orange, white/green, blue, white/blue, green, white/brown, brown.
A. Cable television installations typically use either RG-6 or RG-59 cable. RG-6 is slightly thicker, can run longer distances, and supports digital signals. RG-59 is suited only for analog TV signals.
C. Server Message Block (SMB) is a protocol used to provide shared access to files, printers, and other network resources. It uses TCP ports 137–139 and 445.
A, C. Each IPv6 interface can and often does have multiple addresses assigned to it. IPv6 is backward compatible with IPv4.
B, C. A hub is a device used to link several computers together. Hubs are simple devices that possess no real intelligence, and they work at Layer 1 of the OSI model. Extenders simply allow a signal to propagate for a longer distance, and they also work at Layer 1. Switches are Layer 2 devices, and routers work at Layer 3.
D. RG-6 and RG-59 can, in many cases, be used interchangeably. RG-6 is a better choice because it supports digital signals and has a longer range (304 meters or 1,000 feet). RG-59 can run up to 228 meters (750 feet). Both have impedance of 75 ohms, and both use BNC connectors or F-connectors.
A, D. Multimode fiber and UTP CAT6 and newer support 10Gbps transmission speeds.
B. The Apple Filing Protocol (AFP) was developed by Apple as a file transfer protocol similar to FTP and Server Message Block (SMB). It was the default file transfer protocol on Mac OS until Apple changed to SMB2 in 2013.
B. 127.0.0.7 is the loopback address, used to ping the local network interface. The IPv6 equivalent is ::1.
