True or False: F5 Networks set the standard for the diagram symbols used to represent routers, switches, firewalls, and other devices

False

True or False: ICANN is responsible for restrictions on use of the .com, .org, and .net TLDs

False

True or False: IPv4 and IPv6 use the same packet format

False

True or False: In a rack setup, a device called a KVM allows multiple consoles to connect to a single device on the rack.

False

True or False: Routing Information Protocol (RIP) is an interior gateway protocol that uses a link-state algorithm.

False

True or False: Servers that have a NOS installed require less memory, processing power, and storage capacity than clients because servers are called on to handle only light processing loads and requests from multiple clients.

False

True or False: Static electricity is an electrical charge in motion.

False

True or False: TCP uses a four-step process called a four-way handshake to establish a TCP connection

False

True or False: The 1024-65535 range of ports is also known as the "well-known" range.

False

True or False: The CTRL + S key combination can be used to stop an actively running command.

False

True or False: The Data Link layer attaches a trailer to the end of a packet, and does not include a header

False

True or False: The FTP protocol utilizes UDP, while TFTP uses TCP for data transmission

False

True or False: The Transmission Control Protocol (TCP) is considered to be a connectionless, or best-effort delivery protocol.

False

True or False: The pathping utility sends 10 pings per hop by default

False

True or False: The protocol data unit for the Physical layer of the OSI model is payload, or data.

False

True or False: The transport layer header addresses a receiving application by a number called a MAC address.

False

True or False: UDP provides error checking, but not sequencing

False

True or False: Each organization that provides host services on the public Internet is responsible for providing and maintaining DNS authoritative servers for public access

True

True or False: 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.

True

True or False: Fiber-optic cable comes into two types: single-mode fiber (SMF) or multimode fiber (MMF)

True

True or False: IP is an unreliable, connectionless protocol, as it does not establish a session to send its packets

True

True or False: In general, a Layer 3 or Layer 4 switch is still optimized for fast Layer 2 data handling

True

True or False: In general, an API (application programming interface) call is the method an application uses when it makes a request of the OS.

True

True or False: The Border Gateway Protocol is considered to be a hybrid routing protocol

True

True or False: The TIA/EIA standard for wall jacks in a work area require that at least one outlet be provided for data and one for voice.

True

True or False: The cost of upgrading infrastructure has been a major factor in the slow adoption of IPv6

True

True or False: 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.

True

True or False: The industry standard height for a rack in rack units is 42U

True

True or False: The process of designing, implementing, and maintaining an entire network is called the system life cycle.

True

True or False: The term firmware refers to programs embedded into hardware devices. This software only changes when a firmware upgrade is performed.

True

True or False: UDP port 123 is utilized by the Network Time Protocol service

True

True or False: When using IPv6, two or more nodes on the same link are said to be neighbors.

True

True or False: A 66 block is more suitable for data connections than the older 110 block.

False

True or False: An IPv6 address consists of 128 bits that are written as 10 blocks of hexadecimal numbers separated by colons

False

True or False: Cable that is coated with flame-resistant polyvinyl chloride (PVC) is acceptable for use in plenum areas.

False

True or False: DNS follows a centralized database model, allowing for easier management of DNS records

False

True or False: A hexadecimal number is a number written in the base 16 number system

True

True or False: A master service agreement (MSA) is a contract that defines the terms of future contracts between parties, such as payment terms or arbitration arrangements

True

True or False: After a problem and its symptoms have been identified, a theory regarding a probable cause should be established

True

True or False: At the root level of the DNS hierarchical structure, 13 clusters of root servers hold information used to locate TLD servers

True
