Refer to the network figure above, showing two Ethernet Subnets connected through an IP Router, answer the following question 1-5. The devices in each subnet are connected locally to each other through layer two intermediate devices such as Ethernet switch and ethernet hub. For each device in the subnets, both its Internet Protocol (IP )address and its MAC address (also called the Physical address or the Ethernet address are shown. The subnet mask used by all devices is 255.255.255.240 (which is the same as the prefix length “/28”). 1. If Client #1 wants to send a broadcast packet to all the devices on the left subnet (containing client #1, client #2, client #3) what destination IP address should be used? (Mention in both binary and decimal format.)  2. What is the first and last assignable IP address for the left subnet above (containing client #1 and #3)? (Mention in both binary and decimal format.)

Computer Science Scenario A Company ABC needs to build a simple network in new branch office with the following characteristics: 2 workstations 1 switch 1 server IP address 192.168.1.1 until 192.168.1.3 Draw a network design for this network using all information in Scenario A above. All the devices must be labeled and assign the suitable IP address for the respective device. (You are NOT required to use packet tracer)         The email communication is done via three protocols in general. Explain in detail the THREE (3) protocols.

Select all statements that correctly describe network packet filtering at the IP layer? (Select all that apply) a. IP packet filtering may either be applied to the perimeter of a network or to the individual hosts within a network, but it cannot be applied to both at the same time. O b. IP packet filtering determines which IP packets may flow into or out of a network or a computer. O c. Most IP packet filtering firewalls determine what packets to filter based upon a set of rules which can be configured for a particular network or host. Od. Most IP packet filtering firewalls determine what to filter based upon the IP header fields.

MC9: In wireless LAN communication, MACA is widely used. In this protocol, in order to avoid collision, a sender can send sender is granted the privilege to send a frame to the receiver only after it receives request signal to a receiver. The replied from the receiver. RTS, RTS CTS, CTS RTS, CTS CTS, RTS

) Show the original (unabbreviated) form of the following IPv6 addresses. i. FDEC: 74 : : BOFF : 0 : FFFO ii. 0 : 15 : : 1 : 12 :1213

IP Header has a field TTL ( Time To Live). Which among the following statement best explain the use of TTL(a) It can be used to prioritize the packets(b) It can be used to reduce the delay.(c) It can be used to optimize the throughput.(d) It can be used to prevent packet looping.

dont dont dont post copied one ans only 100% sure else dont answer

IPV4 is a Connection oriented Protocol. * False True Broadcast is the process of sending a packet from one host to a selected group of hosts. * False True The prefix length is the number of bits in the address that gives the Host portion. " False True The metric is used to decide which route appears on the routing table. * True False The throughput value is greater than The Bandwidth Value. * True False O O O O

Q6 A company has 4 branches (LANS) connected through a router. As a network expert you are required to design the IP configuration of these branches in three scenarios: Scenario one: If you have been given 4 class C IP addresses, i.e. one for each branch, what a is the maximum number of devices (hosts) per each branch? Note that the first usable host address is typically reserved as a gateway (router) address. Scenario two: If you have been given only the IP 200.75.64.0/25. Use subnetting b technique distribute the IP's in a table showing the Subnet/Branch IP, usable host range (excluding the gateway address), the gateway address, the broadcast address and the subnet mask for each subnet/branch. Show all you calculation/design steps. Scenario three: If each branch is designed to have up to 4 staff members with only one device each. You have been informed that the number of branches may increase in the future. Using the same given IP in part b, improve your C design to maximize the…
