CNET Lesson 11

HTTP

HyperText Transfer Protocol - the protocol used for transmitting web pages over the Internet

URL

Uniform Resource Locator

Dedicated Server

A server used to fulfill one specific function, such as handling e-mail.

VPS

Virtual Private Server

The ISP allocates you a virtual machine (VM) on a physical server. This is isolated from the other customer instances by the hypervisor

Cloud Hosting

Your website is run on a cloud over several hardware computers, allowing more scalability if demand patterns change.

Shared Hosting

Your website is hosted within a private directory on a shared server. Performance can be severely affected by other sites hosted on the server, because all the sites are competing for the same resources.

HTTPS port number

443

FTP

File Transfer Protocol

Manages download, upload, and directory | File transfers FTP://

SFTP

Secure File Transfer Protocol

- Download (GET) and upload (PUT) only

- Port UDP/69

- Only supports reading (GET) and writing (PUT) files, not directory browsing, file deletion, or any of the other features of FTP

TFTP

Trivial File Transfer Protocol

-Secure

Remote Print Protocol

- Communicate with print monitor over network

- Port 9100

- Internet Printing Protocol (IPP)

- Wed services for devices

- Printer Sharing

SMTP

Simple Mail Transfer Protocol

-Grants server-to-server mail delivery

-If the packet cant deliver the message, it will notify the sender

Mailbox access protocols (MAP)

- Allows client to retrieve messages from the mailbox server

o Connect

o Download email

o Delete email from server

o Disconnect

o Simple, but inefficient (outdated)

MAPS allows for secure MAP connections

*VOIP

Voice over IP

-Has a high priority in the network, as voice packets can not be lost to ensure high quality

Scope

The scope is a range of valid IP addresses available for lease to the DHCP client computers on the network. Microsoft recommends that, each DHCP server in your environment has at least one scope that does not overlap with any other DHCP server scope in your environment.

RTP

Real-time Transport Protocol

-Ensures that packets are being sent at a good speed, and are actually reaching the desired destination

Static IP

An IP address that is manually assigned to a device and remains constant until it is manually changed.

TTL

Time to Live - A value that determines how many hops an IP packet ca travel before being discarded.

ICANN

Internet Corporation for Assigned Names and Numbers

Organizations must register a domain name with a registrar to ensure that it is unique, but the organization that registered the domain name manages its FQDNs (fully qualified domain names).

ICANN manages the Domain Name System (DNS) which is a global hierarchy of distributed name server databases that contain information on domains and hosts within those domains.

SPF

A Sender Policy Framework (SPF) record lists the IP addresses or names of servers that can send email from a particular domain and combats the sending of spam.

Reservation

Reservations allow an administrator to retain centralized management of the IP addresses

An organization has multiple subnets but is only using one DHCP server. How is this possible? (Select all that apply.)

In IPv6, the Stateless Address Autoconfiguration (SLAAC) process can locate routers (default gateways) and generate a host address with a suitable network prefix automatically

What is used to resolve a hostname to an IPv4 address

Administrators use an address (A) record in the domain name system to resolve a hostname to an IPv4 address using the UDP transport protocol over port 53 by default.

What is required on a DHCP server when being configured

The server must have a static ip address

The server must have a scope

What is the significance of port 53?

It allows larger record transfers (512+ bytes)

Which is usually required if the user has an IPv6 address

RTCP

RTP Control Protocol (RTCP) is a session on each RTP stream that monitors the quality of the connection and provides reports that the network stacks can use to tune Quality of Service (QoS) parameters

PoE

Power over Ethernet

nslookup

A utility that is used to test and troubleshoot domain name servers.
