| Question 4 | What is the name of the computer you are working from? SEA-SVR2 | Question 5 | What IP addressing settings are currently configured?10.10.0.12 | Question 6 | Is the computer currently configured for DHCP? How can you tell? Yes, DHCP enabled and it received an ip address of 10.10.0.20 | Question 7 | What is the IP address of the DHCP server from which W2K8yy has obtained its IP address? DHCP Server 10.10.0.11 | Question 8 | If the answer to #7 was not the IP address of the SEA-SVR1 computer, why might this have happened?
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. It fills the destination IPv4 Address as the Target Protocol Address. The Target Hardware Address will be left blank, since the machine is trying to find that. Step 3: The source broadcast the Address Resolution Protocol (ARP) request message to the local network. Step 4: The message is received by each device on the LAN since it is a broadcast.
Zubin Panna NT2640 IP Networking 1. Given the following routing table on a router, which next hop will the router select given the IP packet with the destination address of : 19.48.254.3?

Which one of the following is a feature- of a connectionless protocol like UDP? a) Port Number b) Flow control c) Secure d) Error recovery 3.
The Windows 7 command-line utility that can tell you if the TCP/IP stack of another system on the network is functioning normally is called Ping.exe. 7. The Windows 7 command-line utility that enables you to generate DNS request messages and then transmit them to specific DNS servers on the network is called Nslookup.exe. 8. Most networks use Dynamic Host Configuration Protocol to dynamically assign addresses and configure computers to use them.
Answer: Network and Sharing Center 3. A device that connects one network to another is called a __________________. Answer: Router 4. The most common method for illustrating the operations of a networking stack is the __________________, which consists of __________________ layers. Answer: Open Systems Interconnection (OSI) reference model, seven 5.
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
What it is responsible for is the synchronizing frames, error checking, and the flow control. The third layer of the seven layers of (OSI) network model is the Network layer. The responsibility of the Network layer is managing the logical address information in packets and the delivery. The responsibility in managing logical addressing information and make sure that it is correctly sent to the right destination. The direct data packet generated by Network Layer using information that is stored in a table known as routing table.
