Consider the following statements about PC startup and troubleshooting:
1. POST and firmware initialization occur before the operating system is loaded.
2. Firmware may detect a storage device correctly even when no valid boot entry or bootable operating system is available on it.
3. If an SSD is not detected by firmware, reinstalling Windows on that SSD should normally be the first troubleshooting step.
4. If boot failure begins immediately after a RAM upgrade, memory seating and compatibility should be checked before reinstalling the operating system.
Which statements are correct?

Which statements are correct?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• POST and firmware initialization precede operating-system loading, and firmware detection of a drive does not guarantee that the drive contains a valid bootable system.
• If firmware cannot detect an SSD, hardware connections, compatibility and the storage device itself should be investigated before operating-system installation.
• A failure beginning immediately after a RAM upgrade should first be isolated at the changed hardware component, making statements 1, 2 and 4 correct.

Six identical 4 TB drives are available. Which comparison between conventional RAID 5 and RAID 6 is correct, ignoring formatting and metadata overhead?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• RAID 5 usable capacity is approximately (N−1) times the smallest drive capacity: (6−1)×4 TB = 20 TB.
• RAID 6 uses the equivalent capacity of two drives for dual parity: (6−2)×4 TB = 16 TB.
• RAID 5 normally tolerates one member-drive failure, whereas RAID 6 normally tolerates two.

In Excel, A2 contains 75, B2 contains 65 and C2 contains 55. What value is returned by =IF(AND(A2>=60,B2>=60),AVERAGE(A2:C2),0)?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• A2>=60 and B2>=60 are both TRUE, so AND returns TRUE and the AVERAGE branch is evaluated.
• AVERAGE(A2:C2) = (75+65+55)÷3 = 195÷3 = 65.
• C2 does not have to satisfy the >=60 condition because the AND function in the displayed formula tests only A2 and B2.
• AVERAGE(A2:C2) = (75+65+55)÷3 = 195÷3 = 65.

A folder is accessed across a Windows network share. The user's share permission is Full Control, but the NTFS permission on the folder grants that user only Read access. The user can open files but cannot modify them. Which explanation is most accurate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• When an NTFS resource is accessed through a share, both the applicable share permissions and NTFS permissions affect access.
• Granting broad share access does not override a more restrictive NTFS permission on the underlying object.
• In this scenario the effective result permits reading but not modification.

Consider the following concurrency anomalies:
1. A dirty read occurs when a transaction reads data written by another transaction that has not yet committed.
2. A non-repeatable read can occur when the same row is read twice and a committed update by another transaction causes different values to be returned.
3. A phantom can occur when a repeated range query returns a different set of qualifying rows because another transaction inserted or deleted matching rows.
4. Serializable isolation is designed to permit all of these anomalies freely.
Which statements are correct?

A six-drive RAID 10 array contains three mirrored pairs: A1/A2, B1/B2 and C1/C2, with data striped across the mirror pairs. Which three-drive failure can the array tolerate while retaining one functioning member of every mirror pair?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• RAID 10 survives as long as every required mirrored pair retains at least one usable member.
• Failure of A1, B1 and C1 leaves A2, B2 and C2 available, so every mirror pair still has one copy.
• Each other option destroys both members of at least one mirror pair and therefore loses part of the striped data set.
