is the zone (based on the size of the zone file or the number of resource records used in the zone)? For a multihomed DNS server‚ how many interfaces are to be enabled for listening to and servicing DNS clients on each of the server’s connected subnets? How many total or overall DNS query requests from all of its clients is a DNS server expected to receive and service? In many cases‚ adding more RAM to a DNS server can provide the most noticeable improvements in performance. This is because

Data Communication and Network Comps Assignment 1 Khoa Le - s3103004 Question 1. a) Why is the transport layer not present inside the core network? Marks 3 ● Core Network is the internetworking of routers. ● Transport layer deals with communication between applications. ● The transport layer is not present because it provides additional functions to the core network to compensate for the limitation of the core network layer. ○ In the case of TCP/IP protocol‚ the Transport Layer provide more complex

IP Subnetting – The process of taking a class A‚ B‚ or C IP network and subdiving it into a number of smaller groups of addresses (subnets). Default Router – A host IP setting that refers to the IP address of some router‚ on the same subnet as the host‚ to which the host sends IP packets when the destination is on some other subnet. DHCP – A TCP/IP protocol

of subnetting or breaking the network down into smaller subnets‚ will minimize the broadcast traffic that each network node must process and also increase the performance of the network. For the network infrastructure devices including switches‚ servers‚ router‚ and printers‚ a static IP address should be selected by the network administrator. The subnets that were chosen for the network proposal are broken down into five different subnets. One being used for the six instructional computer labs

An IP address is composed of a network number and a computer number. Your computer can distinguish those two numbers because of something called the subnet mask. The subnet mask is located in a field directly below the IP address on the TCP/IP properties sheet. A simple subnet mask would be something like 255.255.0.0. The numbers that make up the subnet mask
