By admin / August 5, 2022

A company moves a popular website to a new web host. Which of the following will change as a result? The IP address will certainly change. However, with DNS in place the name stays the same and users will never know that the website moved.

Which allocation method can be used with a dynamic host?

Which allocation method can be used with a Dynamic Host Configuration (DHCP) server to assign the same address to the same machine if possible? Automatic allocation tries to assign the same IP to the same device during each lease, if the address is available.

 

Which of the following allows computers on a network to automatically receive address assignment information quizlet?

Which of the following allows computers on a network to automatically receive address assignment information? Dynamic Host Protocol; DHCP is used to automatically assign IP addresses to devices on a network.

 

What technology helps users get connected and stay secure quizlet?

What technology helps users get connected and stay secure? A VPN is used by clients to connect securely to a private network.

 

What transport layer protocol does DNS use?

User Datagram Protocol (UDP)
Just like every application layer protocol, DNS uses the User Datagram Protocol (UDP) on the Transport layer of the TCP/IP model to transport data. UDP is preferred over TCP for DNS because of its speed and lightweight packets.

 

What are the three types of address allocation schemes in DHCP?

Automatic, manual and dynamic allocation.

 

Which of the following hardware devices is used to send information from one computer to another in a network?

Comparison chart
Hub
Definition An electronic device that connects many network device together so that devices can exchange data
Speed 10Mbps
Address used for data tramsmission Uses MAC address
Necessary for Internet Connection? No.

Which of the following allows computers on a network to automatically receive address assignment information?

Which of the following allows computers on a network to automatically receive address assignment information? DHCP is used to automatically assign IP addresses to devices on a network.

 

Which configuration is considered to be a common way to increase security in a wireless network?

There are three principal ways to secure a wireless network. For closed networks (like home users and organizations) the most common way is to configure access restrictions in the access points. Those restrictions may include encryption and checks on MAC address.

 

What technology is used to upgrade a website with load balancing features?

Secure Sockets Layer (SSL) is the standard security technology for establishing an encrypted link between a web server and a browser. SSL traffic is often decrypted at the load balancer. When a load balancer decrypts traffic before passing the request on, it is called SSL termination.

 

What two benefits are a result of configuring a wireless mesh network check all that apply?

What two benefits are a result of configuring a wireless mesh network? Check all that apply. Performance increases when access points are configured in a mesh where all points are connected to each other. Range increases when access points are configured in a mesh where all points are connected to each other.

 

How many Transmission Control Protocol TCP control flags are there quizlet?

How many bits are reserved for the Transmission Control Protocol (TCP) flags? 6; 6 bits are reserved for the 6 TCP control flags. A connection, at which layer, implies that every segment of data sent is acknowledged? transport; A connection at the transport layer implies that every segment of data sent is acknowledged.

 

Which technology helps users get connected and stay secure?

The technology that can help users get connected and stay secure is VPN or Virtual Private Network.

 

What transport protocol ports do DNS and DHCP use?

The port numbers of protocols such as DHCP, FTP, TELNET, HTTP, SMTP etc.
.
Table of port numbers vs Protocols.
Port Number Protocol description
67, 68 The port number 68 is used for DHCP client and 67 is used for DHCP server
53 DNS (Domain Name System)
69 TFTP (Trivial File Transfer Protocol)
70 Gopher services

Why does HTTP use TCP and DNS use UDP?

How does HTTP use TCP and DNS use UDP? HTTP wants to send a message and uses TCP to connect users, break down the message into packets, and sends the message with the transport layer. DNS passes either a domain name or IP address with its packets to the UDP to forward it to the network layer.

 

Why is DNS an application layer protocol?

Protocols at the Physical, Data-Link, Network, or Transport layers do not use names. Only applications need to use names, so DNS is an application-layer protocol because it allows the application to translate a name into a network address.

 

What are the 4 steps of DHCP?

DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement. These stages are often abbreviated as DORA for discovery, offer, request, and acknowledgement.

 

What is DHCP and why it is used?

Dynamic Host Configuration Protocol (DHCP) is a network protocol that is used to configure network devices to communicate on an IP network. A DHCP client uses the DHCP protocol to acquire configuration information, such as an IP address, a default route, and one or more DNS server addresses from a DHCP server.

 

Which of the following option is used to get the IP address of the host server?

DHCP is an application-layer protocol that allows a client machine on the network, to get an IP address and other configuration parameters from the server. It gets information by exchanging packets between a daemon on the client and another on the server.

 

Which of the following is a device that allows a computer to connect to the Internet?

Router. A router is a hardware device that allows you to connect several computers and other devices to a single Internet connection, which is known as a home network.

 

Which hardware is used to convert the digital signals of a computer to signals that can be transmitted through telephone lines?

modem
A modem is a device that translates digital signals from a computer into analog form so that they can be transmitted over analog telephone lines. The modem also translates analog signals back into digital form for the receiving computer.
