Computer File Systems Questions

Multiple choice technology web technology
  1. C:\WINDOWS\system32\Logfiles

  2. C:\WINDOWS\system32\Logfiles\Date

  3. C:\WINDOWS\system32\Logfiles\W8SVX10

  4. C:\WINDOWS\system32\Logfiles\W3SVC1

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

IIS (Internet Information Services) stores log files in the W3SVC1 directory by default, where W3SVC1 represents the default website instance. The path C:\WINDOWS\system32\Logfiles\W3SVC1 is the standard location for the Default Web Site's logs. Options A and B are incomplete paths, while W8SVX10 is not a valid IIS website identifier.

Multiple choice technology programming languages
  1. Easytrieve is an information retrieval and data management system

  2. Easytrieve allows fixed, variable, undefined, or spanned record formats

  3. Matches an unlimited number of files

  4. Cannot call progams written in other languages

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Easytrieve is an information retrieval and data management system that supports various record formats and can match multiple files. However, it CAN call programs written in other languages through mechanisms like CALL statements, making option D the false statement as claimed.

  1. Only for an outfile defined as printer

  2. For any outfile that we write to

  3. Both a & b

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In Easytrieve, the MASK statement is specifically used for formatting output on printer files. It defines how data fields should appear when printed. MASK cannot be used on arbitrary output files, only those defined as printer files.

  1. A. Local Data Sheet, Global Data Sheet, Folder

  2. B. Local Object Repository, Local Data Sheet, Folder

  3. C. Global Data Sheet, Local Object Repository, Folder

  4. D. Local Data Sheet, Global Data Sheet, Local Object Repository

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

By default, creating a new action in QTP/UFT automatically generates a Local Object Repository, a Local Data Sheet, and a corresponding folder structure to store the action's assets.

Multiple choice technology mainframe
  1. VSAM File

  2. Sequential file

  3. Sequential and VSAM

  4. None

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

File-AID is a mainframe file management and editing tool that supports both VSAM (Virtual Storage Access Method) files and sequential files. It provides browsing, editing, and comparison capabilities for multiple file formats. The tool isn't limited to just one file type - its versatility for handling both VSAM and sequential datasets is a key feature.

Multiple choice technology mainframe
  1. VFMT

  2. FMT

  3. UNFMT

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In mainframe file access, different formats include VFMT (Variable Format), FMT (Fixed Format), and UNFMT (Unformatted). These represent different ways data is structured and accessed in mainframe systems. 'All of the above' correctly indicates that these are all valid file format types in mainframe computing environments.

Multiple choice technology mainframe
  1. True

  2. False

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

File-AID is primarily a file browsing, editing, and comparison tool, not a file creation utility. While you can edit VSAM file contents with File-AID, the actual creation and definition of VSAM clusters requires IDCAMS or similar utilities. VSAM file creation involves defining cluster structures that File-AID doesn't handle.

Multiple choice technology mainframe
  1. True

  2. False

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

GDG (Generation Data Group) creation and management requires IDCAMS or JCL with proper DCB parameters. File-AID is for browsing and editing existing dataset contents, not for creating GDG base definitions or managing generations. The claimed answer 'False' is correct.
