Computer File Systems

QSAM (queued sequential access method) files support recording modes F (fixed), V (variable), U (undefined), and S (spanned). Options A (F,V) and B (U,S) are both valid recording mode sets.

COBOL supports multiple open modes including INPUT, OUTPUT, I-O, and EXTEND, as well as file access modes like SEQUENTIAL, RANDOM, and DYNAMIC. Restricting file access or open methods to only INPUT and OUTPUT is incorrect, making the statement false.

In COBOL, the SORT statement is designed specifically for sequential file organization. It cannot process relative, indexed, or other file organization types directly.

The tar command (tape archive) is used to create and extract archive files, bundling multiple files into a single tarfile. This is its core purpose - archiving for backup or distribution. While unrelated to JAR (Java Archive), both serve similar archiving functions in their respective domains.

In Unix/Linux, files on a filesystem are not accessible until the filesystem is mounted to a directory in the directory tree. Mounting attaches the filesystem to the directory structure, making its contents visible and accessible. Before mounting, the files exist on disk but cannot be accessed through normal file operations.

An inode in Unix filesystems stores comprehensive file metadata including file mode (permissions and type), file size, timestamps (creation, access, modification), link count, and pointers to data blocks. All the listed components (A-E) are contained within the inode structure.

Unix file permissions follow the sequence Owner-Group-Others (also called User-Group-All). This ordering is fundamental to how permission bits are organized: first 3 bits for owner, next 3 for group, last 3 for others in the octal representation.

cat file1>>file2 uses append redirection (>>) to add file1's content to the end of file2 without overwriting existing content. Option A overwrites, option B syntax is incorrect, and option D uses input redirection incorrectly.

The Deployment configuration file is where entries are added to exclude files using regular expressions in OpenDeploy. This file controls deployment behavior and filtering rules. The other files (odnodes, odbase, deploy.cfg) are not the correct location for regex-based file exclusion rules.

IEBCOPY is an IBM mainframe utility used for copying and merging partitioned data sets (PDS or PDSE), not sequential files. Sequential files are typically copied using IEBGENER.

CSV and ASCII files are supported formats in SAP BW, so A is true. The RSADMINC table does store flat file load parameters, so B is true. C is false because the correct transaction for flat file parameters is not RSCUSTV7 (it's typically RSBATCH or file-specific maintenance transactions). Since the question asks which statements are NOT true and only C is false, C is the correct answer.

Users get folder access to all folders through the All Users group. This group membership provides access across the folder hierarchy. Other options like Application-specific groups or Folder Sets provide more limited or targeted access, not universal folder access.
