Basic & Fundamental Concepts of Cell Forensics
This section of mobile forensic included 19 MCQs along with their answers and explanation. This is the 1st part of the sub-categories of digital forensic. You can browse all MCQs related to digital forensic from here.
1. Which is NOT a type of data that is used in storage or mobile devices?
- Conceptual Data
- Address Data
- Logical Data
- Physical Data
Answer & Explanation
Answer: (2) Address Data
Explanation:
There are basically three types of data i.e. logical data, physical data, and conceptual data.
And according to perspectives of mobile forensics, logical and physical data is most useful.
2. Which data file form generally NOT included the deleted files?
- Logical Data
- Physical Data
- Conceptual Data
- Both (1) & (2)
Answer & Explanation
Answer: (1) Logical Data
Explanation:
Logical data have limited data storage access which can only hold for GUI extraction, through which deleted records cannot be extracted.
Example: A person sends a message to ‘Y’ and after reading the message the person ‘Y’ deleted the message. In this case, one can’t able to see the message in the sent folder of the phone. However, it can be extracted using the physical data extraction method.
3. Which data form that can be easily understood?
- Conceptual Data
- Logical Data
- Physical Data
- All of the above
Answer & Explanation
Answer: (2) Logical Data
Explanation:
Logical Data are easy to understand because the data is converted in a readable form using the GUI process.
4. Which data can be viewed through the device’s Graphical User Interface (GUI)?
- Logical Data
- Physical Data
- Conceptual Data
- None of the above
Answer & Explanation
Answer: (1) Logical Data
Explanation:
Logical Data are easy to understand because, after the conversion of the data, it is represented as graphics on the output device which generally is monitor or tablet screens.
5. Which is NOT a tool or method for logical data extraction?
- File system
- Android backups
- Advanced Logical
- Chip – off method
Answer & Explanation
Answer: (4) Chip – off method
Explanation:
Tools for logical data extraction are file system, android backups, and advanced logical.
But Chip-off method is a physical data extraction technique.
6. The deleted data can be extracted using
- Logical Data Extraction
- Physical Data Extraction
- Both (1) & (2)
- None of the above
Answer & Explanation
Answer: (2) Physical Data Extraction
Explanation:
Physical data Extraction can be used to extract delete data using the desired extraction method like the chip-off method.

7. Cross tool validation in digital mobile forensic means
- Use more than one forensic tool in the extraction
- Use an open-source tool for validation
- Use of one product tool to confirm the finding of other tools
- Validation of two or more files that originated from the same source
Answer & Explanation
Answer: (3) Use of one product tool to confirm the finding of other tools.
Explanation:
When one tool is used to validate the finding of others it is called a Cross tool validation.
For instance, FTK (Forensic Tool Kit) and BitPim interpret the same result or we can say that the Bitpim tool can be used to validate the finding of the FTK tool.
8. Which of the following is NOT an example of logical data?
- SMS
- GPS
- Web History
- Relational Tables
- Videos
Answer & Explanation
Answer: (4) Relational Tables
Explanation:
Commonly interpreted logical data in mobile forensic are SMS, MMS, Call history, Chats, Videos, web history, bookmarks, GPS, and user-installed applications.
Relational tables are an example of physical data.
9. CDRs in mobile forensic stands for
- Call Details Records
- Compact Disk Rewritable
- Compact Disk Readers
- Call Data Records
Answer & Explanation
Answer: (1) Call Details Records
Explanation:
In Mobile Forensic, CDRs stands for Call Details Records which is crucial evidence.
10. Data that is often used in court or judicial proceedings?
- Logical Data
- Physical Data
- Conceptual Data
- Both 1. & 2.
- None of the above
Answer & Explanation
Answer: (1) Logical Data
Explanation:
Logical data is a readable form of the data which is why they are a common form of data in court and judicial proceedings.
Moreover, even physical data extracted are being converted to Logical data that judicial administrators and common people can understand.
11. In mobile forensic, visual validation means
- The examiner checks for physicals damage signs and validate it with a recovered evidence report by the collected officer.
- The examiner uses the GUI of the mobile device to confirm the findings from the forensic tool.
- The examiners validate the findings of the image file and depict it with the extracted image files from forensic tool applications and hash values.
- None of the above
Answer & Explanation
Answer: (2) The examiner uses the GUI of the mobile device to confirm the findings from the forensic tool.

12. In visual validation, the cell device’s _____ is used to validate the recovered files from a forensic tool.
- GUI
- CUI
- Encase
- Mobile screen
Answer & Explanation
Answer: (1) GUI
Explanation:
In mobile forensics, when Graphical User Interface (GUI) used to verify the finding of a forensic tool then this type of validation is called visual validation.
13. In digital forensic, Hand Carving is defined as
- Removing the ROM chip from the mobile device for forensic examination.
- Use mobile’s undamaged hardware to carving them to a new device to extracted data.
- Uses more than one physical extraction technique.
- Manually navigate the file system to locate encoded raw data.
Answer & Explanation
Answer: (4) Manually navigate the file system to locate encoded raw data.
Explanation:
Hand Carving is the process in which the examiner would manually navigate into the device’s file system and locate its encoded raw data stored in the cell device.
14. What is the full form of SOP in cell device forensic?
- Standard Operating Procedure
- Standard of Preservation
- Safety Operational Procedure
- Set Operational Procedure
Answer & Explanation
Answer: (1) Standard Operating Procedure
Explanation:
SOP addresses to a step by step operating procedure while dealing with digital evidence.
