like a mistyped number can make all the difference in the way a network performs. In the case of the diagram E-1‚ there are many problems like this that can cause the network to not perform the way it is supposed to. Some of these problems include the IP addresses‚ subnet masks‚ and default gateways in this network. All of these things need to be correct and working together in order for the network to function properly. First‚ we must start with the problems with the network shown in the diagram

Q1: If an Ethernet port on router was assigned an IP address of 172.16.112.1/20‚ what is the maximum number of hosts allowed on this subnet? A. 1024 B. 2046 C. 4094 D. 4096 E. 8190 Answer: C Explanation: Given IP address of 172.16.112.1 / 20‚ subnet mask: 255.255.240.0 max. num of hosts =(( 2^12) -2 ) = 4096-2 = 4094 Q2.:An access list was written with the four statements shown in the graphic. Which single access list statement will combine all four of these statements into a single statements that

develop software and hardware that are all compatible with each other. This paper will discuss and describe the 7 layers of the Open System Interconnection model (OSI model) and the layers of the Transport Control Protocol/Internet Protocol model (TCP/IP model)‚ and explain the similarities and differences of each model. The 7 layers of the OSI model consist of: The Application layer (layer 7)‚ The Presentation layer (layer 6)‚ The Session layer (layer 5)‚ The Transport layer (layer 4)‚ The Network

Network Security Some DoS attacks can be avoided by applying vendor patches to the software that has been compromised. Another way to deal with DoS attacks in the case of an attack coming from a number of known IP addresses is to put up a rule to drop all incoming traffic from those known attackers. Yet another way to deal with these types of attacks is to set up packet filters. This will act as a proxy for connections. Once the handshake is validated it will be forwarded to the correct destination

Topology Step 1: Design an IP addressing scheme. Given the IP address block of 192.168.7.0 /24‚ design an IP addressing scheme that satisfies the following requirements: Subnet Subnet A Subnet B Number of Hosts 110 54 The 0 subnet is used. No subnet calculators may be used. Create the smallest possible subnets that satisfy the requirements for hosts. Assign the first usable subnet to Subnet A.

OVERVIEW OF BROAD BAND Definition of Broad Band Broadband is often called high-speed Internet‚ because it usually has a high rate of data transmission. In general‚ any connection to the customer of 256 kbit/s or more is considered broadband. HOW IS BROADBAND DIFFERENT FROM DIAL-UP SERVICE? Broadband service provides higher speed of data transmission—Allows more content to be carried through the transmission “pipeline.” Broadband provides access to the highest quality Internet services—streaming

Creating a subnet by dividing the host identifier A subnetwork‚ or subnet‚ is a logically visible subdivision of an IP network.[1] The practice of dividing a network into two or more networks is called subnetting. All computers that belong to a subnet are addressed with a common‚ identical‚ most-significant bit-group in their IP address. This results in the logical division of an IP address into two fields‚ a network or routing prefix and the rest field or host identifier. The rest field is an identifier
