* Determine the impact on affected switches, network traffic patterns and application performance. Phase 2 * Obtain definitions, traffic pattern information and bandwidth requirements for videoconferencing. Include 20% overhead in bandwidth calculations. * Mark videoconferencing traffic as close to the source as possible on IST subnets. Current best practices recommend IP Precedence 5, PHB AF41, DSCP 34, and CoS 4 for videoconferencing traffic.
Question 15 The Wide Area Network (WAN) design below represents what type of fault-tolerant network design? Question 16 Which QoS design consideration is incorrect? Question 17 Which term is best described by the following definition: “Both NICs are active at the same time, and they each have their own MAC address”? Question 18 Which of the following is one of the two modes of Network Interface Card (NIC) redundancy? (Choose 2) Question 19 The ________ command can be used to display information about current sessions, including source and destination IP addresses and port numbers.
This link is above the Physical layer it is responsible for end-to-end validity of what is being transmitted. Datalink layer is divided into; two sub-layer which is Media Access Control (MAC) that determines the physical addressing of the host. The MAC addresses (physical device addresses) that communicate with other devices within the network. Then there is the Logical Link Control (LLC) sub layer. What it is responsible for is the synchronizing frames, error checking, and the flow control.
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.
(Choose two.) packet switching path selection 3. Refer to the exhibit. When troubleshooting a network, it is important to interpret the output of various router commands. On the basis of the exhibit, which three statements are true?
Unit 3 Assignment 1: Networking Models Review Multiple-choice questions 1. B. The network uses standards defined in TCP/IP RFCs, plus other standards. 2. C. Ethernet D. TCP/IP mapping 3.
The IPX (internet packet exchange) shows up in the third layer of the model. In which is if a device that needs to have communication to it or in a different network then the IPX takes that information and sends it the designation throughout the network. The SPX (Sequenced Packet Exchange) protocol which as the same as IPX is also on layer three so the network is more reliable, datagram connection. The network core Protocol (NCP) is a server routine that is degned to process application requests from Netware (WIKIPEDIA.com). Some of the things that NCP does include file access, printer access, security.
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.
*It could be E, D, or C 20. What values are used when configuring HyperTerminal for connecting to a Cisco router’s console port? *The Serial Port 22. What is the help command in Cisco IOS? *router> help 24.
