d. The two companies must each connect to a Tier 1 ISP. Answer: B. to send packets through the Internet, a company needs just one connection to an ISP. The ISP then commits to having connections to the rest of the Internet. The two companies do not need a connection to each other, or even to the same ISP. 2.
It is an information-sharing model that is built on top of the Internet. The Web uses the HTTP protocol, only one of the languages spoken over the Internet, to transmit data. b. Internet iv. Connects masses of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet. P. 641 1.
Which of the following is a Windows command-line utility for seeing NetBIOS shares on a network? * c. Net view 29. To view eDirectory information on a NetWare 5.1 server, which of the following tools should you use? * d. Novell Client 30. The Nbtstat command is used to enumerate *nix systems.
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.
Homework Unit 2.1 1. What are the four layers of the TCP/IP model? i. Application – Defines the applications used to process requests and what ports and sockets are used. I.
What is promiscuous mode? Allows to capture packets destined to any host on the same subnet or virtual LAN (VLAN). 3. How does Wireshark differ from NetWitness Investigator? Wireshark offers a deep-dive into individual packets.

SEA-SVR1 | Question 2 | What is the default lease duration of a Wired subnet type? 6 Days | Question 3 | What are three recommendations listed in Server Manager for managing the DHCP Server role? 1. Increase fault tolerance by splitting DHCP scopes.
11. C. The PCs use two wires to create a circuit to send data from PC1 to PC2. 12. B. Ethernet defines MAC addresses, but when used in a TCP/IP network, it does not use the addresses, instead relying on IP addresses. 13.
NT1210 Research Paper From what I gathered about “Layer 2 switches” is that the Layer 2 switches use a MAC address from a host NIC card. This makes it to decide where to “forward frames”. Also Layer 2 is a hardware-based control. It uses “application-specific integrated circuits”, which provides “wire speed, high speed, low latency”. OIS layer 7 packets are called “layer 4-7 switches” these are like content switches, content service switches and web switches or application switches… Content switches are normally used for “load balancing” among server groups like on TCP/IP.
Routers R1 and R2 are directly connected via their serial interfaces and are both running the EIGRP routing protocol. R1 and R2 can ping the directly connected serial interface of their neighbor, but they cannot form an EIGRP neighbor adjacency. What action should be taken to solve this problem? Configure both routers with the same EIGRP process
