We can't subnet a network in 30, however it's possible to subnet it in 32. In this case, considering it is an IP Address class C (/24), we have to borrow 5 bitsin the 4th octet, that is, the IP Address203.10.93.0 /24 will turninto203.10.93.0 /29 and mask 255.255.255.248. Dividing the network 203.10.93.0 in 32 it means we will have 8 IP'sper subnet (only 6 of them are valids because the first IP is the Network ID and the last IP is the Broadcast ID, we can't use them).Now let's check out the subnets we'vegot. 1- NID 203.10.93.0 BID 203.10.93.8 2- NID 203.10.93.9 BID 203.10.93.16 3- NID 203.10.93.17 BID 203.10.93.24 4- NID 203.10.93.25 BID 203.10.93.32 And it goes on until 255. As we can see, the IP 203.10.93.30 is in the 4th subnet and it is not a NID and even a BID, so it is a valid IP address.

The dynamic host configuration protocol is used to perform important functions that include configuring the IP address parameters from the DHCP to a post as well as assigning and renewing the IP address from the default pool. It is basically a client protocol that provides the IP host with its own IP address and important configuration information. These can include the subnet mask as well as the default gateway. It is a network management protocol. That assigns IP addresses to different devices nodes or networks. It is used by computer networking services to automatically assign IP addresses to different devices.

500 hosts would require minimum of 9 bits, as 2^9 = 512. Keeping the lat bit of the third byte reserved for hosts, and the rest seven for subnets, we have first seven bit as 1, making the third byte to be 254. Thus Subnet mask is 255.255.254.0. Now the first subnet will be having subnet id as 0, ie. all the seven bits as 0 in the third byte. And for the first address, we will have first seven bits as zero and last bit as 1 in the 4th Byte (Note: All zeros is not a valid IP, and neither is all 1s). So the first address should ideally be 150.20.0.1. Accordingly the last address would be 150.20.1.254

1. application layer-1.1 application layer: provides a means for the user to access information on the network through an application. this layer is the main interface for the user to interact with the application and therefore the network.the application layer is the osi layer closest to the end user, which means that both the osi application layer and the user interact directly with the software application. this layer interacts with software applications that implement a communicating component. such application programs fall outside the scope of the osi model. application layer functions typically include identifying communication partners, determining resource availability, and synchronizing communication. when identifying communication partners, the application layer determines the identity and availability of communication partners for an application with data to transmit. when determining resource availability, the application layer must decide whether sufficient network resources for the requested communication exist. in synchronizing communication, all communication between applications requires cooperation that is managed by the application layer.

What is exhibited topology? There isn’t a lot of information available about this online. Those who have studied information technology or have jobs that are related to technology will be familiar with this. There are two facts that can be said about it though. The first one is letter A and finally, the second fact is letter E. Take note that a collision domain is a network segment. This is usually connected with the use of different repeaters. This is one of the items that are used in order to make wireless connections take place. Without this, how can people connect to the internet?

The correct answers to this question are A, It forwards data packets toward their destination, and E, It acts as an intersection between multiple IP networks. Almost all homes have a router. They are important to a home and business who require Wi-Fi. Routers help connect telephone lines, computers, and printers together. Other devices they can connect are mobile phones, tablets, and gaming systems. There are two types of routers. Wireless routers can connect wirelessly to devices that support wireless connections. The second is a wired router, which connects through wires to the devices ports. All routers are different and can vary in speed and performance.

The answer is D. A routing process aids in selecting the paths of the traffic to other networks connected to a router. This helps the users to connect to an Internet connection via routers and other network hardware. It also allows close-proximity devices connected to the same router have the same IP addresses. This lets the network that they are of the same group. A router also allows multiple devices to connect to the Internet wireless and all at the same time. This has been a great improvement since the Internet was launched to the public where decades ago one needed to connect a cable between a computer and a telephone modem just to be on the Internet.

A. There are two broadcast domains in the network. F. There are seven collision domains in the network.Only router can break up broadcast domains so in the exhibit there are 2 broadcast domains: from e0 interface to the left is a broadcast domain and from e1 interface to the right is another broadcast domain -> A is correct. Both router and switch can break up collision domains so there is only 1 collision domain on the left of the router (because hub doesnt break up collision domain) and there are 6 collision domains on the right of the router (1 collision domain from e1 interface to the switch + 5 collision domains for 5 PCs in Production) -> F is correct.

The answer for the question here would be the option B and that would be provides access to the rest of the network through switching, routing, and network access policies. The three layer heirarchial model that is shown is a very good example of using a graphic model in order to show how things work. This is a very good way of showing exactly how access is being provided across a network. The three layer model allows for more complex manuvering, designing, and manipulating of any computer network. Of the three layer heirarchial model, each layer is responsible for a different part of the operating network. There is a distribution layer that provides support to the other two layers which are the access layer and the core layer. It is the distribution layer where things such as routing and access to the wireless access network or better known as WAN. The distribution layer has mainly the routers and the switches of the computer located there.

The correct answer to this question is D, 00-12-3f-32-05-of. MAC in MAC Address stands for media access control address. Devices such as computers and laptops have MAC addresses. This address is a unique identifier, which is assigned to the NIC, which is the network interface controller. Along with being of a device, it can also be used as a network address for technology such as Bluetooth, Wi-Fi, and Ethernet. Both wired and wireless devices have Mac addresses. They are linked to the network adapters hardware. MAC addresses may also be referred to as burned-in address, networking hardware address, or the physical address.
