Test Yourself on Exam #70-271: Supporting Users
Exam #70-271 Supporting Users and Troubleshooting Microsoft Windows Desktop Operating Systems is one of two exams required for the new Microsoft Certified Desktop Support Technician (MCDST) certification. I’d like to thank Microsoft for making course materials available to me so I could craft some sample Q&A for this exam.
1. In Windows XP, the Windows Security dialog box includes a button labeled “Change Password” that provides access to a Backup function that may be used to create a password reset disk. Which of the following statements about a password reset disk are true? (Choose all correct answers.)
A. The password reset disk allows users to change their password without knowing the old password.
B. Password reset disks can be used only for domain accounts, not for local computer accounts.
C. Users cannot change their passwords and create a password reset disk at the same time.
D. Users must create a new password reset disk each time they change their passwords, or if an administrator resets their password manually.
E. Best practice dictates that users should create password reset disks and keep them in a safe place.
2. When a user logs onto a specific Windows XP computer for the first time, what kind of user profile is copied automatically to generate a new user profile for that user?
A. Local user profile
B. All users profile
C. Roaming profile
D. Mandatory profile
E. Default profile
3. Which of the following limitations apply to NTFS compression when it’s used to manage space on a hard disk? (Choose all correct answers.)
A. Compressed files are decompressed when accessed by the operating system, which can slow down access to files.
B. NTFS compression and NTFS encryption (EFS) may be used separately, but not together.
C. NTFS compressed file sizes are not factored into disk quota calculations, so compressing files does not benefit users subject to disk quotas (though it does save disk space).
D. NTFS compression provides little or no benefit for already-compressed files (e.g., .zip files, audio files, compressed image files and so forth).
E. NTFS compression can be applied to files in the ‘SystemRoot’ directories; this will make that computer unusable.
4. Which of the following conditions may be true if you receive this error message while trying to install Windows XP:
INF File Textsetup.sif is corrupt or missing Status 14 SETUP CANNOT CONTINUE
A. The Windows XP CD you’re using is scratched, smudged or dirty.
B. The CD-ROM drive is not working correctly, or the CD-ROM might be vibrating or wobbling too much for the laser to read its data accurately.
C. On computers with multiple CD-ROM drives, the system may be looking for files on the wrong drive.
D. On overclocked systems, decoding errors may occur when extracting compressed files from the Windows XP CD-ROM.
E. The files on the Windows XP CD-ROM you’re using are corrupted.
5. Which of the following actions that are taken when you select the Repair option on a LAN or high-speed Internet connection corresponds to the command nbtstat -RR at the command line?
A. Renew your Dynamic Host Configuration Protocol (DHCP) IP address lease.
B. Flush the Address Resolution Protocol (ARP) cache.
C. Reload the NetBIOS name cache.
D. Send a NetBIOS name update to the local network segment.
E. Flush the local Domain Name System (DNS) cache.
F. Register your computer’s DNS name.
1. Answers A, C and E are correct. Indeed the purpose of the password reset disk is to permit users to choose a new password without remembering the old one. Thus, answer A is correct. Because password reset disks work only for local computer accounts and not for domain accounts, answer B is incorrect. If the Backup button in the Change Password dialog box is chosen, any changes to the existing password in that dialog are ignored. Thus, they can only either change their passwords or create a password reset disk during any single visit to this dialog box, making answer C correct. Once created, a password reset disk will work even if the user’s password is reset one or more times between the disk’s creation date and the date upon which it gets used. Also, a password reset disk may be used more than once, making answer D incorrect. Indeed, best practice does dictate that users should create password reset disks and keep them in a safe place in order to avoid their malicious use by unauthorized personnel. Thus, answer E is also correct.
2. The correct answer is E, default profile. Answer A is incorrect because a local user profile is created after the first local login to a Windows XP computer is completed. This kind of profile is resident on one specific computer and is unique to the user account to which it is tied. Answer B is incorrect because the all users profile is a convenience profile designed to make it easy for all users on a specific computer to share application settings and to make those applications generally available. Answer C is incorrect because roaming profiles are stored on the network and are copied to a local computer when a user logs on. Roaming profiles must be created through a special entry in the Users branch of the Computer Management console; there’s nothing automatic about their creation. Answer D is incorrect because a mandatory profile is like a roaming profile in that it resides elsewhere on the network and must be designated manually through the Users branch of the Computer Management console. (What makes them different from roaming user profiles is that mandatory profiles do not save user desktop changes or customizations after a user logs out.) Answer E is correct because the default profile acts like a template to create the basis for new local user profiles each time a new local user logs into a Windows XP machine.
3. All answers to this question are correct.A is correct because NTFS decompresses files as they’re read from the drive, which can slow down file access times. Answer B is correct because encrypted files may not be compressed, and compressed files cannot be encrypted in NTFS. C is correct because disk quotas use only uncompressed file sizes when calculating disk consumption against quota limits. Answer D is correct because already-compressed files seldom decrease significantly in size when compressed further using NTFS compression. Because answers A through D are correct, answer E is also correct.
4. Answers A, B, C and D are correct, as documented fully in Knowledge Base article 310064 (support.microsoft.com/default.aspx?scid=kb;en-us;310064). Essentially, this error message relates to problems that can interfere with accurate access to the Windows XP CD-ROM or in trying to access the wrong CD-ROM drive. Answer E is wrong because CD-ROM files are write-once. If they’re pressed properly, CD files are static and cannot become corrupted.
5. Answer D is correct because nbtstat -RR at the command line causes a NetBIOS name update to be broadcast to the local network segment. Answer A is incorrect because renewing the DHCP release corresponds to ipconfig /renew. Answer B is incorrect because flushing the ARP cache corresponds to arp -d *. Answer C is incorrect because reloading the NetBIOS name cache corresponds to nbtstat -R. Answer E is incorrect because flushing the local DNS cache corresponds to ipconfig /flushdns. Answer F is incorrect because registering the computer’s DNS name corresponds to ipconfig /registerdns.
