...Question 1 1.1) The organization was built on bus topology which works best with only a limited number of devices connected. The reason users are experiencing slow speeds to additional users were added. The bus network topology at optimal speeds when there are less than 12 device on the network. 1.2) They could create a new network with the same design for the new users thus decreasing the pressure on the current network.

...I have decided the best way to visualise how the application will look like from the user prospective will be to make a storyboard. This story board I created illustrates how the user is interacting with the GUI of the application. To produce this, I used a software called Balsamiq Mockups 3, the advantage of using this is that I could hyperlink storyboards together and run a simulation of the software. This was very helpful to me because it allowed me to visualise how the GUI will work and look before implementing it. The Story board is located in appendix A.

...Good morning team, as you know there was a site survey performed for our client Sifers-Grayson on Monday morning. This meeting is to review any issues uncovered during the site survey and the recommendations we can offer our client. Sifers-Grayson already has two redundant wide area network connections, but we need to explain why having two separate (redundant) wide area network connections from the campus area network to the internet is important. We need to convey to our client that the most important reason for our recommendation of installing two separate (redundant) wide area network connections is to avoid a single and even multiple points of failure in communication or data access with/between their employees or clients. A failure of this magnitude could result in the loss of business and their professional image being altered. If you have a single point of failure and it fails you, then you have nothing to rely on. If you put in a secondary (or tertiary) method of access, then when the main connection goes down, you will have a way to connect to resources and keep the business operational (Shimonski, 2017). There a several options we can recommend when it comes to two separate WANs connections. We will focus on the following two. The first is having a WAN line and WAN hardware redundancy by having your two leased-lines that are both active. Both connections having a back-up are more expensive but more reliable because the router and line has a back-up. An alternative...

IPTS 5Q: uses effective co-planning and co-teaching techniques to deliver instruction to all students; Performance Activity 52: How does the teacher use assessment to drive instruction? Assist a special needs student. Describe how is assessment different for a special needs student in this classroom? The competent teacher uses assessments to drive instruction to plan and determine what to teach, how to teach content, and how content will be measured. Unfortunately, Ms. Boerema and I did not get to finish the lesson, but if we had more time, we would have given students an exit to complete. The exit slip assesses the following: the type of conflict that occurred in the short story, Amigo Brothers, and was there a winner. This type of formative assessment evaluates if students can identify the type of conflict that occurred in the story and if there was a winner. Since I work with students receiving special education services, assessments include accommodations and modifications to provide for students while taking an assessment. IPTS 7I relates to this performance activity of how a teacher is familiar with the type of assessment and how it assesses the effectiveness of instruction for each student. I learned assessment evaluates student...

...POODLE VULNERABILITY The Secure Sockets Layer SSL protocol is a cytographic protocol which allows client-server applications to communicate across a network in a way designed to prevent eavesdropping and tampering. The Secure Socket Layer version 3 was adopted when the Secure Socket Layer version 2 was discovered to have multiple serious security flaws but since its adoption additional security issues have been discovered. POODLE being one of them. POODLE (Padding Oracle On Downgraded Legacy Encryption) is a vulnerability that allows a man-in-the-middle attacker to decrypt cipher text using a POODLE attack. The attack exploits a weakness in Cipher Block Chaining (CBC) encryption in SSL in which part of the encrypted data cannot be verified by the receiver when decrypting. The attacker exploits this weakness by replacing part of the encrypted data and forwarding it on to the server. In most cases the server will reject the attackers request but the attacker keeps sending the request until the server accepts the request....

...Question 3: The presentation of financial statement information in common-size amounts rather than dollar amounts means that the items in the financial statement are presented as a percentage, instead of a dollar amount (Edmonds, Tsay, & Olds, 2011). This type of presentation is sometimes more meaningful when analyzing two or more organizations of differing size against each other, as well as analyzing these organizations over various time periods (Edmonds, Tsay, & Olds, 2011). Essentially, common-size amounts allow an individual to quickly compare different organizations, or the same organization’s performance over time by reducing the bias of dollar amounts (Edmonds, Tsay, & Olds, 2011). Common-size amounts present a better comparison of the organizations financial health and enable the organization to better analyze internal and external trends (Edmonds, Tsay, & Olds, 2011). Most organizations use debt-to-equity ratio, profitability, gross profit margin or operating profit margin percentages in the financial statement to quickly compare different organizations or to compare the organizations financial health (Cheng, 2014). Debt-to-equity ratio assesses a proportion of...
