WGU C702 Final ReviewWhich Event Correlation Approach checks and compares all the fields systematically and intentionally
for positive and negative correlation with each other to determine the correlation across one or multiple
fields?
graph-based approach
rule-based approach
field-based approach
automated field correlation Correct Answer: D
Minimizing the tangible and intangible losses to the organization or an individual is considered an
essential computer forensics use.
A. True
B. False Correct Answer: A
Which field type refers to the volume descriptor as a primary?
A. Number 2
B. Number 0
C. Number 1
D. Number 3 Correct Answer: C
This phase of EFI consists of initialization code that the system executes after powering the EFI system
on. It manages platform reset events and sets the system so that it can find, validate, install, and run the
PEI.
A. SEC
B. PEI
C. DXE
D. BDS
E. RT Correct Answer: A
Most of the initialization happens in this phase. Using the Hand-Off Block List (HOBL), it initializes the
entire system physical memory, I/O, and MIMO (Memory Mapped Input Output) resources and finally
begins dispatching DXE Drivers present in the system Firmware Volumes (given in the HOBL). The DXE
core produces a set of EFI Boot Services and EFI Runtime Services. The EFI Boot Services provided are
allocating memory and loading executable images. The EFI Runtime services provided are converting
memory addresses from physical to virtual while handing over to the kernel, and resetting the CPU, to
code running within the EFI environment or within the OS kernel once the CPU takes the control of the
system.
A. SEC
B. PEI
C. DXE
,D. BDS
E. RT Correct Answer: C
This phase initializes the CPU, temporary memory, and boot firmware volume (BFV). It locates and
executes the Pre Initialization chapters (PEIMs) present in the BFV so as to initialize all the found
hardware in the system. Finally, it creates a Hand-Off Block List with all found resources interface
descriptors and passes it to the next phase i.e. the DXE phase.
A. SEC
B. PEI
C. DXE
D. BDS
E. RT Correct Answer: B
In this phase, the BDS interprets the boot configuration data and selects the Boot Policy for later
implementation. This phase works with the DXE to check if the device drivers require signature
verification.In this phase, the system loads MBR boot code into memory for Legacy BIOS Boot or loads
the Bootloader program from the EFI partition for UEFI Boot. It also provides an option for the user to
choose EFI Shell or an UEFI application as the Boot Device from the Setup.
A. SEC
B. PEI
C. DXE
D. BDS
E. RT Correct Answer: D
At this point, the system clears the UEFI program from memory and transfers it to the OS. During UEFI
BIOS update the OS calls the run time service using a small part of the memory.
A. SEC
B. PEI
C. DXE
D. BDS
E. RT Correct Answer: E
Which of the following basic partitioning tools displays details about GPT partition tables in Windows
OS?
A. DiskPart
B. Gparted
C. Disk Utility
D. Fdisk Correct Answer: A
How large is the partition table structure that stores information about the partitions present on the
hard disk?
A. 32-byte
B. 64-bit
,C. 64-byte
D. 32-bit Correct Answer: C
How many bits are used by the MBR partition scheme for storing LBAs (Logical Block Addresses) and the
size information on a 512-byte sector?
A. 128
B. 64
C. 256
D. 32 Correct Answer: D
Which of the following basic partitioning tools displays details about GPT partition tables in Windows
OS?
A. DiskPart
B. Gparted
C. Disk Utility
D. Fdisk Correct Answer: A
What component of a typical FAT32 file system consists of data that the document framework uses to
get to the volume and utilizes the framework parcel to stack the working portion documents?
A. Boot Sector
B. FAT Area
C. Data Area
D. Reserved Area Correct Answer: A
Which file system used in Linux was developed by Stephen Tweedie in 2001 as a journaling file system
that improves reliability of the system?
A. Ext2
B. Ext
C. Ext4
D. Ext3 Correct Answer: D
How many bit values does HFS use to address allocation blocks?
A. 8
B. 16
C. 64
D. 32 Correct Answer: B
Striped set (min 2 disks) w/o parity and no fault tolerance. Any disk failure destroys the array.
A. Raid 0
B. Raid 1
C. Raid 10
D. Raid 2
, E. Raid 3
F. Raid 4
G. Raid 5
H. Raid 6 Correct Answer: A
Mirrored set (min 2 disks) w/o parity. Provides fault tolerance from disk errors and single disk failure.
A. Raid 0
B. Raid 1
C. Raid 10
D. Raid 2
E. Raid 3
F. Raid 4
G. Raid 5
H. Raid 6 Correct Answer: B
Hamming Code Parity - Disks are synchronized and striped in very small stripes, often in single
bytes/words.
A. Raid 0
B. Raid 1
C. Raid 10
D. Raid 2
E. Raid 3
F. Raid 4
G. Raid 5
H. Raid 6 Correct Answer: D
Striped set with dedicated parity or bit interleaved parity or byte level parity. - This mechanism provides
an improved performance and fault tolerance similar to RAID 5, but with a dedicated parity disk rather
than rotated parity stripes.
A. Raid 0
B. Raid 1
C. Raid 10
D. Raid 2
E. Raid 3
F. Raid 4
G. Raid 5
H. Raid 6 Correct Answer: E
Block level parity - Identical to RAID 3, but does block-level striping instead of byte-level striping. In this
setup, files can be distributed between multiple disks. Each disk operates independently which allows
I/O requests to be performed in parallel.
A. Raid 0
B. Raid 1
C. Raid 10
