Lab 5 Lab 5.2.1 Each NIC must have a unique MAC address because all data is forwarded based on the destination address so without it the switch wouldn’t know where to send the data. 5.2.2 Information on the Support tab: Address Type – DHCP IP Address – 10.39.108.176 Subnet Mask – 255.255.252.0 Default Gateway – 10.39.110.15 5.2.3 Physical address of the NIC for this connection: 00-0C-29-20-53-9E 5.2.4 Manufacturer of the NIC: VMWare 5.2.5 IP address of the NIC and default gateway: 10.39.108.176 10.39.110.1 5.2.6 Steps in an ARP Request and Response: Step 1: When a source device want to communicate with another device, source device checks its Address Resolution Protocol (ARP) cache to find it already has a resolved MAC Address of the destination device. If it is there, it will use that MAC Address for communication. To view your Local Address Resolution Protocol (ARP) cache, Open Command Prompt and type command "arp -a" (Without double quotes using Windows Operating Systems). Step 2: If ARP resolution is not there in local cache, the source machine will generate an Address Resolution Protocol (ARP) request message, it puts its own data link layer address as the Sender Hardware Address and its own IPv4 Address as the Sender Protocol Address.
The two companies must each have at least one Internet access link. 2. Which of the following standalone devices can be found near the Internet edge, with a primary purpose of providing some type of network security between an enterprise or SOHO TCP/IP network and the Internet? (Choose two answers) B. IPS D. Firewall 3. Which of the following answers lista concept that is likely to be true about a single POP?
Lab 2.1: Connecting Computers Exercise 2.1.1 Media, Interface, Signal, Pattern, and Timing are all necessary to establish a network. Media is needed for the physical structure on which the signal will travel. Interface is needed so the computer can access the media. Signal is the means of transmission such as electrical signal. Pattern is the format for the signals to be interpreted.

More specifically, software that performs some useful function for a user. Computer network: A combination of many components that work together so that many different devices can communicate. Computer networking: The gerund form of the term computer network. Email: Electronic mail.
Some of the things that NCP does include file access, printer access, security. Using TCP/IP (transfer control protocol) which is also on layer three and four of the model, and it allows a network to communicate through ort 80 or also known as HTTP (Hypertext Transfer Protocol. These protocols would be chosen based on the security, and the devices it needs to access the internet. In anything to do with networks and computers security is always number one so putting a WPA2 enterprise with a wireless router, in place would be very beneficial for Kudler so the router and the network can have a passcode in place so there will be no outside influences to hack the system. The authentication of the Radius server will be used for the WPA Enterprise which the router uses is 802.
An analysis of the network systems in use The current network system that Patton-Fuller is using is a network that is One GB, using Cat 6 and single Mode Fiber which gives greater speeds and trusted reliability. The technologies that are in place also have an intelligence built into them that alerts the network operations center when any malicious intend to the system is being done. The network also has a build in redundancy to prevent collision. Patton-Fuller has been using a CISCO System 7609 Router and a CISCO Systems ASA 5510 VPN (Virtual Private Network) Router. This helps with secure VPN and Internet traffic through the ASA 5510 VPN Router.
Question 15 The Wide Area Network (WAN) design below represents what type of fault-tolerant network design? Question 16 Which QoS design consideration is incorrect? Question 17 Which term is best described by the following definition: “Both NICs are active at the same time, and they each have their own MAC address”? Question 18 Which of the following is one of the two modes of Network Interface Card (NIC) redundancy? (Choose 2) Question 19 The ________ command can be used to display information about current sessions, including source and destination IP addresses and port numbers.
Unit 7 Assignment Christopher Place Kaplan Online University Unit 7 Assignment Question 1 A Media Access Control Address (MAC Address) is also known as a physical address and is used on the media access control protocol sublayer and is assigned to routers ports to identify them to a physical address. The reason for the router having more than one MAC address is because it has two different ports assigned for different reasons and in this case it is for internet and LAN. An IP address is an address associated with every device on a network and a computer so that the internet knows where the web servers and mail servers can send their data to. The reason for the two different IP addresses on the router is because every router has two of them one is called the WAN interface or public IP address and the other is called LAN interface or private IP address. The WAN interface is the side that is connected to the internet which is why it is public and the LAN interface is the side that is connected to the network and that is why it is private.
IS 589 Course Project Professor James Marion VoIP Implementation and Quality/Latency Issues Gaines Williams Introduction The term VoIP stands for voice over Internet Protocol. VoIP is related to the terms IP telephony and Internet telephony. At the most basic level, VoIP technologies enable analog telephone communications to be digitally transferred and routed over data networks—this can be done over a wide area network (WAN), a local area network (LAN) or the Internet. These two packets of communications, digitized voice and data, coexist and travel throughout a network. A third packet, video, has become an increasingly important network consideration for organizations because of its large bandwidth requirements.
