Dynamic Host Configuration Protocol (DHCP) is a protocol/service that enables a network administrator to assign IP addresses dynamically, without having to configure each machine individually. WINS is an NT protocol/service that maps IP addresses to NetBIOS names. DNS is a protocol/service that maps IP addresses to hostnames. Classless Inter-Domain Routing (CIDR) is also known as supernetting because, unlike subnetting that borrows host bits for a subnet, network bits are borrowed for the host address. The benefit of CIDR is that large numbers of routing table entries can be summarized into a smaller number of entries |

The purpose of a bridge is to ____________.
a. Amplify a data signal and all accompanying noise
b. Filter data on a network by MAC address
c. Connect network subnets
d. Prepare signals for transmission on a WAN |
|
Definition
Filter data on a network by MAC address
A bridge connects different segments of a network in order to expand the scope of the network. Bridges filter data on a network by MAC address to isolate traffic on a network segment. Bridges are used as a tool on overloaded networks. By filtering data based on MAC address, they efficiently transmit data between sending and receiving devices. Traffic between segments is reduced and network throughput is increased with a bridge. Routers connect network subnets. CSU/DSUs prepare signals for WAN transmission. Repeaters are network devices that amplify data signals and all accompanying noise. |

Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive emails from a remote server to a local email client. POP3 allows you to download email messages on your local computer and read them even when you are offline.
The Internet Message Access Protocol (IMAP) is a mail protocol used for accessing email on a remote web server from a local client. IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Both protocols are supported by all modern email clients andweb servers.
Main difference between IMAP and POP3:
The POP3 protocol assumes that there is only one client connected to the mailbox. In contrast, the IMAP protocol allows simultaneous access by multiple clients. IMAP is suitable for you if your mailbox is about to be managed by multiple users.
Simple Mail Transfer Protocol (SMTP) is the standard protocol for sending emails across the Internet. SMTP uses TCP port 25. |

ST connectors are one type of industry-standard connector for fiber-optic cable.

The connectivity device that is used to connect cable to a T-connector is a BNC connector. RJ-45 connectors are used with UTP as the transmission medium. Universal Serial Bus (USB) connectors are used to connect USB-compatible peripherals to a computer or a USB hub. |

Your network is connected to the Internet. As the network administrator, you install packet filtering on the router that connects your network to the Internet. After you configure packet filtering, users on the network are no longer able to download files. What did you do to create this problem?
a.You blocked port 80
b.You blocked port 21
c.You blocked port 25
d.You blocked port 110 |
|
Definition
You blocked port 21
Packet filtering is the process of filtering (discarding) data based on source address, destination address, port number, or domain name. Packet filtering is a software implementation of a firewall. A port is an address that identifies an application that is associated with data. Some of the well-known port numbers are port 15 for NETSTAT, port 21 for FTP, port 23 for Telnet, port 25 for SMTP, port 53 for DNS, port 80 for HTTP, port 110 for POP3, and port 119 for NNTP.
In this question, the problem is the users can no longer download files. In this question, you have blocked port 21, which is associated with File Transfer Protocol (FTP). FTP is responsible for downloading files over a TCP/IP network. This is the protocol that a user configures in order to download files.
The correct answer is: You blocked port 21 |

Identify the Quality of Service (QoS) mechanism that can fragment large packets and interleave smaller packets in amongst the packet fragments.
a.Policing
b.CRTP
c.Traffic shaping
d.LFI |
|
Definition
LFI
LFI is the Quality of Service (QoS) mechanism that can fragment large packets and interleave smaller packets in amongst the packet fragments. As a result, the smaller packets can exit a slow-speed interface sooner, and not experience excessive delay.
Link Fragmentation and Interleaving (LFI) and RTP Header Compression (cRTP) are both link efficiency mechanisms, which attempt to make a more efficient use of relatively limited WAN bandwidth.
cRTP can take the Layer 3 and Layer 4 headers of a Real-time Transport Protocol (RTP) packet (used to carry voice over IP traffic), which total 40 Bytes in size, and compress them down to only two or four Bytes (two Bytes without UDP checksums and four Bytes with UDP checksums).
Policing and traffic shaping are both traffic conditioners, each of which can set a bandwidth limit on traffic. However, policing has the ability to drop excess packets, while traffic shaping delays excess traffic. |

Crossover
You reach for a crossover cable, which will connect one user's computer directly to another user's computer.
