How Computer Programs That Wipe Hard Drive Work

It can be an advocacy but usually, companies that dispose old computers when they buy new units often donate the equipments to institutions and to some people who need personal computers. This is a widely acceptable practice. But are you ready to give much more than the worth of the personal computer you are donating? You might not be fully aware of it but when you are giving your old personal computer to other people, you are also giving the recipient the opportunity to access your old files and information saved previously on the hard disk.

Even if you have deleted the files in the Windows operating system and in the Recycle Bin, there would always be traces of the deleted file somewhere within the hard drive of the computer. The simple process of deletion would only remove the shortcuts to the files. In actuality, the files are still there, though you could hardly trace them. But imagine if in the long process of donating, the personal computer goes to the possession of an expert who could be able to restore and retrieve the deleted files. There are many recovery and restoration software available in the market that could facilitate instant retrieval of deleted files.

Will you be willing to afford to lose sensitive information like trade secrets, personal information, confidential data, bank and credit account numbers and contact details of clients? Much more, will you be willing to take the risk of sharing such important and confidential information to some unscrupulous people who might use the data inappropriately, maliciously and fraudulently? If not, then, it is high time you wipe hard drive of your computer.

Disk wiping is the process of erasing saved data on storage devices like compact discs, thumb drives and hard drives. When you wipe hard drive, you are ensuring that all previously deleted files on the personal computer would never ever be recovered or accessed even with the use of the most powerful data recovery software. Wiping hard drive is actually working by overwriting the entire hard drive not just once but several times. Thus, you can rest assured that no data or file would ever remain in the computer memory for life. To put it simply, it is impossible to retrieve data that have already been overwritten. The process is irreversible.

How does the process work? When you wipe hard drive, the process generally overwrites the whole disk with zero or one. A reformat would follow. The overwriting process takes on and repeats itself several times, solidifying the security purpose. That is the reason why such computer programs usually take some time to complete. When you wipe hard drive, you are practically disk wiping applications by overwriting master boot record, the partition table and each sector present in the computer hard drive.

When you wipe a hard drive, you are ensuring the safety and confidentiality of all files that had been saved and later on erased from the computer memory. Such pertinent data and information would never ever be accessed by anyone, especially the unauthorized ones.

MCSE 70 290 Certification Primer

Microsoft Certifications are one of the most widely acclaimed, pursued, and achieved technical certifications in the IT industry. The demand for Microsoft Certified Professionals in the job market is increasing every year.

Microsoft offers a number of certification levels depending on specific areas of proficiency and nature of job. Some of the certifications pertaining to networking are

Microsoft Certified Professional (MCP)

Microsoft Certified System Administrator (MCSA)

Microsoft Certified System Engineer (MCSE)

Each certification level has certain exams associated with it. You can decide the appropriate certification exam based on your experience, skills, and interests.

Benefits of Microsoft Certifications

Microsoft Certifications provide a standard method for testing employee skills. The certifications provide employers a valid benchmark for evaluating the employee's abilities. This will provide you the recognition and reward as per your expertise.

Microsoft Certifications offer prospective employers a baseline to judge your knowledge, skill, and expertise in the field. Certifications can provide added advantage if you are at the same level of experience as another person without certifications.

Certifications are a valuable tool if you have no or very little experience. The certifications that you hold can prove and reassure your employers and consultants about your knowledge in the field. This will help you secure good job as well as negotiate a good salary.

Pre-Requisite Experience (Recommended) for Microsoft Certifications

To pursue this certification you should have at least 1 year of experience in:

Implementing and administering a network operating system in environments with 50 to 26,000 supported users, in approximately 3 to 150 physical locations.

Implementing network services and applications such as file and print services, database services, messaging services, proxy server or firewall services, dial-in server services, and Web hosting.

Implementing and administering a desktop operating system.

Designing a network infrastructure with 3 or more domain controllers.

Significance of Microsoft Certifications for Microsoft Windows Server 2003

Microsoft has developed independent certification requirements for Microsoft Windows Server 2003. An aspirant can certify directly for MCSE/MCSA in Windows 2003 if they are new to certification process. If the aspirant is already a certified MCSE /MCSA in Windows 2000, then they can follow the upgrade path for MCSEs in Windows 2000 to secure Windows 2003 Certifications. If the aspirant certifies in MCSE for Windows NT4.0, they can earn MCSE in Windows 2003 by following the upgrade path for MCSEs in Windows NT4.0.

The exams are slightly more challenging than their Windows 2000 counterparts, but they will actually test your hands-on knowledge since that is the most important part of ensuring that a certification is credible.

Exam 70-290: Managing and Maintaining a Microsoft Windows Server 2003 Environment

Exam 70-290 is the first in the series of the core exams for MCSE certifications.

When you pass the Managing and Maintaining a Microsoft Windows Server 2003 Environment (MCSE 70-290) exam, you achieve Microsoft Certified Professional (MCP) status. You also earn credit toward the following certifications:

Core credit towards Microsoft Certified Systems Administrator (MCSA) on Microsoft Windows Server 2003 certification

Core credit towards Microsoft Certified Systems Engineer (MCSE) on Microsoft Windows Server 2003 certification

MCSE 70-290 exam objectives are

Objective 1: Managing and Maintaining Physical and Logical Devices

In this objective you will need to demonstrate expertise in managing and maintaining physical and logical devices. As an administrator, you should understand Basic and Dynamic disks, RAID configuration and troubleshooting, driver signing, and the use of tools, such as Device Manager and Hardware Troubleshooting Wizard. Familiarize yourself with Device Manager and the warning and disabled icons found when problems are present on installed devices.

Objective 2: Managing Users, Computers, and Groups

This objective includes many topics, so you should be prepared to face many questions that fall into this category. Have a healthy introduction to profile management, user and group accounts, permissions, and troubleshooting. Practice a lot on GPOs and perform a variety of administrative tasks, including configuration of desktop settings, control of security settings, assignment of scripts, redirection of folders, and software distribution. Also, get a clear understanding on inheritance and filtering.

Objective 3: Managing and Maintaining Access to Resources

Knowing how to configure, monitor, audit and troubleshoot NTFS permissions based issues are one of those most important areas that you need to know this concept thoroughly and also be sure to brush up on your share permissions and share/NTFS permissions interaction. Do not forget to brush up on how folder and file permissions can change or stay the same when copying or moving within a drive or between drives.

Objective 4: Managing and Maintaining a Server Environment

In this objective you'll find questions from topics, such as Event Viewer, System Monitor, software updates (including the functionality of Microsoft's Software Update Service or SUS), Remote Assistance, disk quotas, print queues, performance objects and IIS 6.0. Spend time understanding IIS topics around Web sites, Virtual and physical directories, files and host and cname records in DNS. New to Windows Server 2003 is SUS. Understand clearly how SUS is used for deploying and managing client and server critical updates.

Objective 5: Managing and Implementing Disaster Recovery

In this objective you'll find questions on ASR, VSS, backing up files and system state data, configuring security for backup operators, verifying backup jobs, managing media, restoring and scheduling backups and recovering from server hardware failures. You should take some extra time to get familiar with the various types of backups that Windows Server 2003 supports, as well as the various configuration options that are available to you. Practice making backups of different types and then practice restoring them.

MCSE 70-290 Exam Model

Most of the questions in the MCSE 70-290 exam are multiple choice type. The questions require the "best" answer from several close responses. Other questions may present an implementation scenario, requirements, and a proposed solution and then ask if the solution meets all of the requirements or combinations of the primary and secondary requirements. Microsoft has introduced some testing innovations for the certification exams. These question types present a more realistic visual representation of the tasks a MCSE would do in future. These are

Hot Area Questions

This type of question requires indicating the correct answer by selecting one or more elements within a graphic.

Active Screen Questions - This type of question asks you to configure a dialog box by changing one or more elements.

Drag and Drop Questions - This type of question asks you to drag source objects to appropriate targets within a work area.

Build List and Reorder Questions - This type of question asks you to indicate the correct answer by building an answer list. In a Build List and Reorder question, you need to build a list by dragging the appropriate source objects to the answer list and then placing them in the correct order based on criteria defined in the question.

Create a Tree Questions - This type of question asks you to create a tree structure. You indicate the correct answer by dragging source nodes to the correct locations in the answer tree. Nodes consist of text and a small icon.

Windows Simulation Questions - This type of question asks you to indicate the correct answer by performing specific tasks such as configuring and installing network adapters or drivers, configuring and controlling access to files, and managing hardware devices. Many of the tasks that systems administrators and systems engineers perform can be presented more accurately in simulations than in most traditional exam question types.

You can get hands-on experience on new set of questions that are available in Whizlabs MCSE 70-290 Exam Simulator. This will help you plan your study regime to ensure success.

Passing Score

Microsoft has normalized scoring for all MCP exams, so the same passing score applies to all exams. 700 is now the minimum passing score for all MCP exams. However, the maximum score (which used to top out at 1000) varies per exam, depending on the complexity of the skills measured.

Time Limit

The exam duration is 175 minutes with 45 questions. You will have plenty of time to answer the exam questions, so there is no need to rush. If you have spare time available, you can double check the questions and ensure that you have read them correctly and actually answered the question as intended.

Exam Result

Instead of reporting results based on major categories for exam objectives as it used to, Microsoft is now providing numerical scores and bar graphs for "skills clusters". Visually, the bars in the exam report show you how well you fare in each skills cluster. If bars that represent cluster scores are close to one end of the graph, they indicate stronger skills; bars near the other end indicate weaker skills. Please store your exam results in both paper and electronic format for later reference.

Sample Questions

Question 1

You are a systems administrator for TicTacToe Toy Manufacturers. All servers in the company run on Microsoft Windows Server 2003. The company's Active Directory infrastructure consists of a single domain hosted on two domain controllers named Tic1 and Tic2.

Tic2 experienced a hard disk failure, and hence has been taken offline. Tic2 remained offline for some days while all Active Directory updates were made to Tic1. You proceed to restore the data from backup while ensuring that the latest Active Directory changes are replicated to Tic2.

How should you restore the lost data from backup?

Choices:

Perform authoritative restore on Tic1.

Perform normal restore on Tic2.

Perform primary restore on Tic2.

Perform authoritative restore onTic2.

Correct Choice: B

Explanation:

Choice B is the correct answer.

During a normal restore operation; Backup operates in non-authoritative restore mode. That is, any data that you restore, including Active Directory objects, will have their original update sequence number. The Active Directory replication system uses this number to detect and propagate Active Directory changes among the servers in your organization. Because of this, any data that is restored non-authoritatively will appear to the Active Directory replication system as though it is old, which means the data will never be replicated to your other servers. Instead, if newer data is available from your other domain controllers, the Active Directory replication will update the restored data. Hence, choices A, C, and D are incorrect.

Question 2

You are a systems administrator for Blueberry Packaging Industries. All servers in the company run on Microsoft Windows Server 2003.

You create a folder named Custom Package on the company's file server to contain the company's files. You share this folder as Custom Package. The folder is configured with default NTFS permissions and default share permissions. The file server is located in a secure room.

Within the shared folder, Managers should be able to add and change files and subfolders. Employees in the Sales and Packers department should be able to change and delete files and subfolders. All other employees should only be able to view the files.

All Sales employees are members of the Sales domain local security group. All Managers are members of the Managers domain local security group. The Packers are members of the Packers global security group.

How should you modify share level permissions on the Custom Package folder so that the appropriate users have the minimum required privileges? (Choose all that apply)

Choices:

Grant Change share permissions to Managers.

Deny Full Control share permissions to Managers.

Grant Change share permissions to Sales.

Grant Full Control share permissions to Sales.

Grant Change share permissions to Packers.

Grant Full Control share permissions to Packers.

Deny Full Control share permissions to Everyone.

Remove Everyone from the share permissions list.

Correct Choices: A, C, and E

Explanation:

Choices A, C, and E are the correct answers.

Change permissions allow the users to create, delete, and change any files and folders in the shared folder, provided the users have appropriate NTFS permissions on the files and folders. The default NTFS permission in Windows Server 2003 is Read for Everyone and the default share level permissions grant Read access to Everyone. You should not remove Everyone from the share permission list. By default, share level permissions grant Read access to Everyone.

How to Prepare for Microsoft Certification?

Following are the steps to prepare for Microsoft certification.

MCSE exams are not easy, as advertised on many websites. The MCSE Certifications are tough, so plan to put in a lot of time and effort getting ready for your certification exams. Get all information you can about the certification exams and then start working towards your goal.

Get hands on experience. The first step in the preparation for any Microsoft Certification is hands on experience with the related product. For MCSE, the aspirant needs to have at least a year of working experience and for MCSA, the minimum recommended time of experience is 6 months. If you are not working anywhere, it will help, if you can volunteer your IT skill services to gain valuable experience.

You can set up a small network at home to practice. Setting up the home network will give a great opportunity to learn. You can practice the lab exercises in the home network as and when you study. This will give you a better understanding of the theories than just studying the exam guides.

Get trained in the related product. If possible, try to get training in the related product in a Microsoft Authorized Training Center. You can use training resources to supplement your skills and experience. You can also use the Microsoft Official Curriculum for the related exam as well as Microsoft Press books that are available for the exam.

For Exam 70-290, the main areas that you need to concentrate are

Automated System Recovery (ASR)

Diskpart utility

Diskraid utility

Emergency Management Services (EMS)

File Replication Service (FRS)

Group Policy Management Console (GPMC)

Open File Backup

Password Backup and Restore Wizard

Remote Assistance

Remote Desktop

Shadow copying of shared folders

Software Update Services (SUS)

Virtual disk service

Permissions -Share and NTFS

Users, Computers, and Groups

Use the preparation guide of the exam that you want to take and read it thoroughly. You should know all the exam objectives of MCSE 70-290 covered in the exam preparation guide.

Use practice test software packages. Whizlabs MCSE 70-290 Exam Simulator is an example.

Do NOT use Braindumps. Braindumps might help you get the certification, but you will lack important practical knowledge about the product. Hence, your prospects of landing a good IT job will be less. Some brain dumps deliberately mislead you. So BEWARE!

You can participate in any online discussion forum, where you can participate in an ongoing dialogue and even ask doubts if you have any. You are sure to get the right guidance.
