Networks Chapters 1-4
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
