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.
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?
To identify where wireless devices such as APs should be placed in the network you should do what kind of test? Site Survey What does the WiFi Alliance do? Promotes Wi-Fi technology and certifies Wi-Fi products if they conform to certain standards. A company installs an 802.11g AP to rive its employee's wireless access from their cubicles. Carl's cubicle is 40 feet from the AP, Paul's is 20 feet, and Mark's is 100 feet.
What is the history of the TCP/IP model? Why was it created? Use your textbook and Internet research to support your answer. In 1970's the DOD sponsored a project to create a standardized networking model called TCP/IP. Pg 61 - 3.2.1 exercise 3.2.1 Using Figure 3-1, define each layer of the OSI model in your own words and state what each layer provides.
1. IP hosts in two different company TCP/IP networks send IP packets to each to each other through the Internet. Which of the following is true about the Internet Connection that must exist so that the packets can flow between the two companies? B. The two companies must each have at least one Internet access link.
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.
In telecom closet 2, from the punch down block, to the switches, to the wall plates, and on to the offices workstation, plus one shared printer, cabling will change to Cat 5e UTP, using 1000 Base-T technology, achieving a throughput of 1000Mbps. A safety feature on Ethernet Lans, is its access method, CSMA/CD. CSMA/CD, means that your NIC checks the network to make sure it is not busy before transmitting, if two nodes do transmit at the same time having a collision, it will send out packets to inform other nodes of a data collision, then the NIC waits for the network to be inactive before retransmitting. On the
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.
If the Global Name Zone had the name, it will respond back to the user but if it doesn’t had the query then the authoritative zone will check for the name. 2. Explain the modifications necessary to DNS for accommodating Read Only Domain Controllers (RODC). How is this different from the way DNS handles ordinary domain controllers?
Considered outside the scope of the project is connecting the database to any user information that requires Common Access Card (CAC) authentication. The project main deliverable will be a working Microsoft Office Access Database that has the ability to email users and request the user to send certificates electronically to the ITS. This project will create a useable database that can be updated and used by the ITS and it will track all training required by regulation send email reminders to users when training requirements are
