T or F? Each type of cable has a prescribed bend radius, which is the radius of the maximum arc into which you can loop a cable without impairing data transmission.
T
T or F? In general, a Layer 3 or Layer 4 switch is still optimized for fast Layer 2 data handling.
T
T or F? The fundamental difference between a switch and a router is that a switch belongs only to its local network and a router belongs to two or more local networks.
T
T or F? The industry standard height for a rack in rack units is 42U.
T
T or F? When using IPv6, two or more nodes on the same link are said to be neighbors.
T
T or F? A hexadecimal number is a number written in the base 16 number system.
T
T or F? Fiber-optic cable comes in two types: single-mode fiber (SMF) or multimode fiber (MMF).
T
T or F? The Border Gateway Protocol is considered to be a hybrid routing protocol.
T
T or F? A 66 block is more suitable for data connections than the older 110 block.
F
T or F? An IPv6 address consists of 128 bits that are written as 10 blocks of hexadecimal numbers separated by colons.
F
T or F? Cable that is coated with flame-resistant polyvinyl chloride (PVC) is acceptable for use in plenum areas.
F
T or F? DNS follows a centralized database model, allowing for easier management of DNS records.
F
T or F? F5 Networks set the standard for the diagram symbols used to represent routers, switches, firewalls, and other devices.
F
T or F? IPv4 and IPv6 use the same packet format.
F
T or F? ICANN is responsible for restrictions on use of the .com, .org, and .net TLDs.
F
T or F? In a rack setup, a device called a KVM allows multiple consoles to connect to a single device on the rack.
F
T or F? Routing Information Protocol (RIP) is an interior gateway protocol that uses a link-state algorithm.
F
T or F? TCP uses a four-step process called a four-way handshake to establish a TCP connection.
F
T or F? The CTRL + S key combination can be used to stop an actively running command.
F
T or F? The Data Link layer attaches a trailer to the end of a packet, and does not include a header.
F
T or F? The FTP protocol utilizes UDP, while TFTP uses TCP for data transmission.
F
T or F? The Transmission Control Protocol (TCP) is considered to be a connectionless, or best-effort delivery protocol.
F
T or F? The Transport layer header addresses a receiving application by a number called a MAC address.
F
T or F? The pathping utility sends 10 pings per hop by default.
F
T or F? UDP provides error checking, but not sequencing.
F
T or F? At the root level of the DNS hierarchical structure, 13 clusters of root servers hold information used to locate TLD servers.
T
T or F? Each organization that provides host services on the public Internet is responsible for providing and maintaining DNS authoritative servers for public access.
