Do you think ICMP can identify routers on networks. Yes/No 3. The ARP maps ________________ addresses to _________________ addresses. 4. The RARP maps _______________ addresses to _________________ addresses.
It is the portion of the IP address that can be used to produce hosts or user IPs for devices. 4. Which of the following is a private IP address and can’t be routed across the Internet? d. 221.24.250.20, because it over the limit of a class C private address. The range for class C private is 192.168.0 to 192.168.255.
NT1210 5/12/15 Intro to Networking Unit 7 Assignment 1 Homework Questions 1. b. It uses a telco service called packet switching. 2. a. Switched analog circuits b. Dedicated digital circuits 3. c. Routers use Layer 3 and ignore Layers 1 and 2. d. Routers discard old data-link headers and insert new data-link headers as part of their logic, which treats each interface’s lower-layer details as independent from each other.
Question 46: Consider the network diagram presented below, let’s assume that both switches are capable of auto negotiating Ethernet speeds of 10, 100, and 1000 Mbps. Let’s also assume the switches do not support MDIX. Refer to the network diagram. Identify what the Layer 1 issue would be in this topology. Question 47: What is the administrative distance of Open Shortest Path First (OSFP) routing protocol?
Which of the following facts are in common between both of the Ethernet standards discussed in this chapter, 10 BASE-T and 100 BASE-T? (Choose two answers) 8. Which of the following answers best describes the definition of a cabling pin out? 9. Which of the following is true about what happens when a PC NIC connects to a switch using 100 BASE-T?
Adam Odegard NT2640 Weak 1 INFORMATION ON IP ADDRESS CLASSES In order for systems to locate each other in a distributed environment, nodes are given explicit addresses that uniquely identify the particular network the system is on and uniquely identify the system to that particular network. When these two identifiers are combined, the result is a globally-unique address. IP address is a code made up of numbers divided by three dots that finds particular computers on the internet. They are 32-bit binary numbers, consisting of 2 sub identifiers, which identify the host and network. It is four octets of numbers from 0-255 represented in decimal form.
4 | 12 | 16 | 4,094 | 11111111.11111111.11110000.00000000255.255.240.0 | /20 | x.y.N*16.0 | 12) Explain the reasoning behind the concepts of “subnet zero”? Subnet Zero If a network address is subnetted, the first subnet obtained after subnetting the network address is called subnet zero. Consider a Class B address, 172.16.0.0. By default the Class B address 172.16.0.0 has 16 bits reserved for representing the host portion, thus allowing 65534 (216-2) valid host addresses. If network 172.16.0.0/16 is subnetted by borrowing three bits from the host portion, eight (23) subnets are obtained.
Randy Michael NT 1210 Lab 1.1 Professor Chibuzo Onukwufor 4/1/15 Lab 1.1 1: Convert the decimal value 127 to binary. Explain the process of conversion that you used. Decimal Number | Binary Number | Remainder | 127 - | 64 | 63 | 63 - | 32 | 31 | 31 - | 16 | 15 | 15 - | 8 | 7 | 7 - | 4 | 3 | 3 - | 2 | 1 | 1 - | 1 | 0 | Binary | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | Decimal | 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 | Conversion | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 0 | I took the decimal and divided it by two giving 1 for the remainders and 0 if it did not have a remainder. 2: Explain why the values 102 and 00102 are equivalent. They are equivalent because they represent the powers of 10 3: Based on the breakdown of the decimal and binary systems in this lab, describe the available digit values and the first four digits of a base 5 numbering system.
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?
