The answer is that GPT stores a backup partition table at the end of the disk. This is a defining characteristic because GPT, or GUID Partition Table, uses 64-bit logical block addressing and maintains a primary partition table at the start of the disk along with a secondary, or backup, copy at the very end for redundancy, unlike MBR which relies on a single, vulnerable partition table in the first sector. On the CHFI exam, this distinction tests your understanding of disk forensics and data recovery, as a corrupted MBR can be fatal, while GPT’s backup allows for reconstruction. A common trap is confusing the backup table location with MBR’s boot code area, where MBR stores partition entries in a limited 64-byte space. Remember the memory tip: GPT has a “backup buddy” at the end, while MBR is a “lonely leader” at the start.
CHFI Storage Forensics and File System Analysis Practice Question
This CHFI practice question tests your understanding of storage forensics and file system analysis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE of the following are characteristics of the GPT (GUID Partition Table) compared to MBR?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Partitions are identified by a Globally Unique Identifier (GUID)
GPT uses GUIDs, supports up to 128 partitions, stores a backup partition table at the end, and uses 64-bit LBA. It does not store partitions in the boot code area.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Partition information is stored in the boot code area
Why it's wrong here
GPT stores partition table in a dedicated partition table area, not in boot code.
✗
Uses a 32-bit Logical Block Address (LBA)
Why it's wrong here
GPT uses 64-bit LBA.
✓
Partitions are identified by a Globally Unique Identifier (GUID)
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
OSPF neighbours must agree on key parameters.
Router ID selection can affect neighbour relationships and LSDB output.
OSPF cost influences the preferred path.
A route can appear in OSPF information but not become the installed route.
TExam Day Tips
→Check area mismatch first when OSPF adjacency fails.
→Review passive interfaces when a network is advertised but no neighbour forms.
→Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
How this comes up in practice
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
