B, E 11. E Read the Diagram 1. A 2. B 3. B 4.

Use the network diagram below and the additional information provided to answer the corresponding questions. [15 points]

2. Please fill out the scanner sheet as you go along in the exam. You will not be given extra time at the end of the exam to fill it out.

If necessary, use the back of the exam pages for the rest of your answers. Do not use other sheets of paper. Please write legibly; if I cannot read your answer, I will count it wrong.

Ω is discretised using h = 1/n (where n is even) and 3n . 2 The domain is illustrated in Figure 3.1 for n = 6. The

Schaffer needs to create a layout with a specialized team that has these: DMZ, Intranet, Internal Network, Proxies, Firewall Configuration, and mobile users The DMZ is needed to separate the company from the internet. This is a secured area into which the company should place servers providing Internet services and facilities (for example, web servers). It is also good to have because if anyone attacks the machine is hardened to defend from attacks. These servers don't have any information in the internal network.

There are 3 security features about Hamachi: (1) Encrypted communications：Secure communications using AES 256-bit encryption, over public and private networks; (2) Centralized access controls: Control network access and usage, including password management, network authentication, network locking, and ongoing network membership; (3) Network / client configuration management：Configure default settings for individual networks and clients, with support for full, restricted and minimal client interface modes

This protocol use Dijkstra algorithm. It maintains a complex data base, also called as link state database, which contains full information about the remote routers and the exact network topology. The goal from this protocol is to provide similar information about network connection to each router, so each router can calculate the best route to each network this is happen when each router generates information about itself and pass these information to other routers in the network so each router make a copy of this information without changing it.

Each layer has a specific function and the layers work together to allow an application to send data over a computer network without really specifying the exact protocols and/or physical wiring within each layer. In line with the figure above, when the first CEO sends an email message to the second CEO, email ‘application worker’ firstly prompts the first CEO to enter a message and specify that the receiver is the second CEO. The application worker then creates the necessary data package with message contents and the destination email address and send s this to a ‘transport worker’. The transport worker provides transport integrity. The transport worker may establish a connection with the receiver (second CEO); monitor the overall

Step 1: Construct a network diagram for the project. (NOTE: EF for activity H should be 19)

You are allowed to bring pens, a two-sided cheat sheet (8.5 x 11 inches), pencils, simple function calculators to the exam.

Using the provided network diagram, write a program that finds the shortest path routing using the Bellman-Ford algorithm. Your program should represent the fact that your node is U. Show how the iterative process generates the routing table for your node. One of the keys to your program will be in determining when the iterative process is done.
