Solved in 3 steps
- Discuss the advantages and disadvantages of associating with remote file systems (stored on file servers) a different set of failure semantics from that associated with local file systems.Consider the following case: Alice, Bob, and Eve are all users on a system using the Unix File Access Control system. Alice wants to create a file (that she will own) that she and Eve can both read and edit, but Bob can't. Assign user IDs to all users and create any groups that are necessary, then use this information to specify the file's access control settings.The logical size of a given file is 12400 bytes in a magnetic disk with each cluster consisting of 8 sectors, each of which having a fixed size of 512 bytes. How many clusters will the above file take? What will the physical size of the above file be (in bytes)? 3. What is the slack space in this case?
- Please showing working out and explaination for the following: Find types of File System Type (e.g., FAT32, NFTS, EXT3 etc.)Discuss the challenges of maintaining synchronization and consistency in a distributed file system. How do techniques like distributed locks and two-phase commit protocols address these challenges?A Prof believes that all the effort spent on access control matrices and access control lists is a waste of time. He believes that all file access permissions for every file should be restricted to the owner of that file, period. Describe five unique scenarios where he is wrong, that is, where users other than a file’s owner need some kind of allowed access privileges.
- In a distributed file system, how can exception handling be employed to ensure data consistency and reliability across multiple nodes or servers?The following utility tool(s) may be used by us in order to investigate the File System (such as NTFS) of a partition or volume:The grouping of answer choicesDISKPART \sFSUTIL \sWMICAnything that was discussed beforeWhere do these two file-access strategies diverge? Exactly how dissimilar are these two options?
- Are you in agreement with the statement that "there is no idea of client and server sides of a communication session" while using an application that facilitates peer-to-peer file sharing? There are both positive and negative reasons for doing this.Assume a system can sustain 2,000 users for the sake of argument. MPX.pdf should be made accessible to 1,990 users through a Unix security mechanism that enables them to see the file. 'How will you deal with the ten people who don't have access to the file?'Files is one of the components of an operating system security, show with example how file permission in Unix operating system provide layer of security?
