...Unit 4. Site-to-Site Connectivity Scenario First, open the console and Services Site Links and see how long this set up for replication. Then create an object in AD and expect to replicate. Compare this with the time set in "Site and Services", and is equal to or less this ok (ok with the settings that were set) If you are the highest: Run the command repadmin / showreps and put the result here. Open the Event Viewer logs and see what errors appear. When you create a site object in Active Directory, you associate one or more Internet Protocol (IP) subnets with the site. Each domain controller in a forest is associated with an Active Directory site. A client workstation is associated with a site according to its IP address; that is, each IP address maps to one subnet, which in turn maps to one site. Active Directory uses sites to: * Optimize replication for speed and bandwidth consumption between domain controllers. * * Locate the closest domain controller for client logon, services, and directory searches. * * Direct a Distributed File System (DFS) client to the server that is hosting the requested data within the site. * * Replicate the system volume (SYSVOL), a collection of folders in the file system that exists on each domain controller in a domain and is required for implementation of Group Policy. * The ideal environment for replication topology generation is a forest that has a forest functional level of at least...

...5.4 Sub-Objective Name Configuration of client connectivity Objective Tested Describe roaming Bloom Level 3 Question Stem A client roams from AP1 to AP2 connected in the same Layer 2 domain because the signal from AP1 has degraded and he has better signal reception from AP2. What will happen to the frames that AP1 has created for the client? Options (A) The frames will be dropped. (B) The frames will be sent to the client via the WLC to the AP2. (C) The frames will be forwarded to AP2 over the wired infrastructure. (D) The client once connected to AP2 will request for the frames. (E) Correct Answer(s) C Explanation The frames will be carried over the wired infrastructure to AP2 because it houses the client’s MAC address and L2 traffic follows the MAC address. 5.1 Sub-Objective Name Configuration of Client Connectivity Objective Tested Identify...

...offerings for Internet access to select the one that should be used. (10 points) I think internet connection should be made using (DSL) and Broadband. I decided on this option because AT&T’s Digital Subscriber Line service (DSL) offers highly secure, high-speed, cost-effective business Internet connectivity over existing landlines without interrupting voice services. AT&T Broadband Internet Services Provides a single point of contact for business’ connectivity needs, access the Internet and Intranet, stream audio and video and transfer large amounts of data and provide access to remote workers. 2. How should the existing and new campus locations be connected to each other? (10 points) The Existing and new campus can use a fiber optic cabling in order to connect the two campuses. Fiber optic cables are less expensive, there is less signal degrading, non flammable and the best option compared to other competitors. On the other hand the campuses can request a static IP address through the internet provider. Through this the two campuses can connect on a network via WAN 3. Should the two locations share an Internet connection? (10 points) Yes, for this scenario sharing a single internet connection between the two with be sufficient and will turn out to be less cost effective. 4. Compare the advantages, disadvantages, and cost of fiber optic cable, 5 GHz wireless bridges, and free space optics as a means to interconnect the campus buildings to the IT wing of...

...Site to Site Connectivity Scenario With the two site taking long to replicate or not replicating at all I would first check the time that is set to replicate and if there is even a connection at all. Open the console and service site link and note how long this configuration is set for replication. Then I would try and duplication the problem. Create a new object in the Active Directory and replicate. Compare the time it took to the time set on the configuration. There are many other ways you could troubleshoot this issue. Open command prompt and run repadmin /?. This will show you many helpful commands you can run to troubleshoot this issue. In repadmin /showrepl command helps you understand the replication topology and replication failures. It reports status for each source domain controller from which the destination has an inbound connection object. The status report is categorized by directory partition. Use the /repsto parameter to display outbound partners. The /replicate command tests replication success after you remove suspected fault conditions without waiting for the replication schedule to open /replsummary will Identifies domain controllers that are failing inbound replication or outbound replication, and summarizes the results in a report. Like I noted before there are many options to troubleshoot this another tool I would like to leave you with is a command line tool DCDiag. This will analyze the state of one or all domain controllers in the forest and reports...

If people try to access the website and it doesn’t work — for whatever reason –the website becomes worthless. An example is server uptime, it’s important to ensure the possible or current visitors don’t get an error trying to load the site therefore it will be wise to invest in good hosting which will be done. Another example is broken links, it is essential to double check that there are no dead links on the site. Another key aspect to consider is Mobile responsiveness, ensuring that the site can handle different screen sizes and slow connections. Clarity The second key aspect to usability is clarity. If you distract or confuse your visitors, they will either need more time to find what they came for, or they might forget their initial goal all together. Either way, they will not experience the website as user-friendly or chances are that they will leave dissatisfied and with no intention of coming back. This is why I have decided that a clear and usable design can be achieved through: * Simplicity – Focusing on what’s important. If you don’t distract your visitors they will be more likely to do what you want them to do. * Familiarity –Sticking to what people already know. There is nothing wrong with looking at other sites for inspiration. * Consistency –Creating a consistent...

...Task 1 (C) – JIT2 Risk Management C. Recommendations Create an implementation plan in which you recommend ways of implementing, monitoring and adjusting the BCP. For the task of creating a Business Continuity Plan (BCP), I will follow a logical and systematic formula for implementation, monitoring and reviewing the plan for United Health Group. The goal is to minimize the impact of any disruption by containing it within a predictable and predetermined period of time. To do this, I recommend that this plan be developed and implemented with as many preventative controls, contingency resources, and procedures designed to allow the organization to quicky bounce back from any long-term business interruption. With this document I’ll present a workable DR plan that focuses not only on safeguarding critical data but also on the restoration of all normal business functions. The process for developing a sound Disaster Recovery plan will involve many layers of detail from the obvious to the not so obvious. Since disasters are by their nature unpredictable, this DR plan must be thorough enough to provide a certain amount of relief to know that if one does occur, the affects on the business will not be catastrophic. Disaster Recovery Topics: 1. Secure executive-level leadership commitment Senior leadership buy-in and support is critical to the long-term success of any enterprise level initiative. Disaster Recovery and Business Continuity Plans are no different. Further...
