| 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?
Typically, the utilization of switch ports is low and can lead to higher costs compared to other implementations of the hierarchical star. 2. Placing horizontal cross-connections and work group switches closer to equipment outlets is called FTTE (fiber-to-the-telecommunications enclosure). The benefits include savings
Whichsecondary value will the routers use to determine the router ID? The highest IP address among the active interfaces will be used. 14. Refer to the exhibit. Routers R1 and R2 are directly connected via their serial interfaces and are both running the EIGRP routing protocol.
OSI Model: Open System Interconnection * Is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers 7) Application Layer | 6) Presentation Layer | 5) Session Layer | 4) Transport Layer | 3) Network Layer | 2) Data Link Layer | 1) Physical Layer | * The model group’s communication functions into seven logical layers. A layer serves the layer above it and is served by the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer. (Wikipedia) 2.
I Exercise 8.1.1 Class A networks are defined as those that use only the first byte ( also called an octet) of the address as the network identifier. The rest of the address is considered the host identifier. In this type of network, the number of possible networks is much smaller than the number of hosts that can be connected to the same network. If the IP address in Figure 8- 1 belongs to a class A network, what is the network ID and what is the host ID? 110 (network ID), 10.10.1 (host) What are the binary values of the host ID and the network ID?
2. Determine the protocol numbers for the protocol names: Protocol | NUMBERS | References | IPv4 (Internet Protocol version 4) | 4 | (Protocol Numbers, 2013) | IPv6 (Internet Protocol version 6) | 41 | | TCP (Transmission Control Protocol) | 6 | | UDP (User Datagram Protocol) | 17 | | ICMP (Internet Control Message Protocol) | 1 | | VRRP (Virtual Router Redundancy Protocol) | 112 | | IPSEC ESP (Internet Protocol Encap Security Payload | 50 | | L2TP (Layer Two Tunneling Protocol) | 115 | | OSPF (Open Shortest Path First) | 89 | | EIGRP (Enhanced Interior Gateway Routing Protocol) | 88 | | 3. Determine the correct ICMP type based on the description provided. ICMP Message Description | Type | Code | Echo | 8 | RFC792 | Echo Reply | 0 | RFC792 | Time Exceeded | 11 | 0 – Time to Live exceeded in Transit1 - Fragment Reassembly Time Exceeded | Port Unreachable | 3 | 3 - Port Unreachable | Fragmentation Needed | 3 | 4 - Fragmentation Needed and Don't Fragment was Set | 4. What are the valid ranges of protocol numbers?
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? Address/Mask Next hop 19.46.0.0/16 Interface 0 19.47.0.0/16 Interface 1 19.52.43.0/24 Router 1 default Router 2 a) Router 2 b) Router 1 c) Interface 0 d) Interface 1 2. 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.
a. To keep intellectual property rights to the technology inside the company 8. The TCP/IP and OSI models have some obvious differences, like the number of layers. Think about the more commonly used version of the TCP/IP model discussed in this chapter, and then think about how to talk about TCP/IP using OSI terms. Which of the following is
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.
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.
