A technician is troubleshooting an enterprise virtualization server configured with a hardware RAID 5 array consisting of four hot-swappable SAS SSDs. The RAID management utility reports that the array status is degraded due to Disk 2 failing and going offline. Additionally, virtual machines hosted on the array are experiencing high write latency because the hardware RAID controller has automatically switched from write-back to write-through mode following a battery backup unit (BBU) fault alert. Which TWO of the following actions should the technician perform to restore array fault tolerance and optimal write performance without risking data loss?

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Hot-swap the failed SAS SSD in slot 2 with a spare drive of equal or greater capacity and initiate an array rebuild.; Replace the faulty RAID controller battery backup unit (BBU) to safely re-enable write-back cache operation.

Cevap

The technician must hot-swap the failed SAS SSD in slot 2 with a compatible replacement drive to rebuild parity data, and replace the RAID controller's faulty battery backup unit (BBU) to safely re-enable write-back caching.
To fix a degraded RAID 5 array, the failed member drive must be physically replaced with a healthy drive of equal or greater capacity and rebuilt using existing parity information. To resolve write performance issues caused by a disabled controller cache, replacing the degraded battery backup unit (BBU) allows the controller to safely re-enable write-back cache without exposing cached data to power loss risks.

Adım Adım Çözüm

1
Identify the cause of array degradation and reduced write performance.
Disk 2 hardware failure caused the RAID 5 array to enter a degraded state, while a faulty BBU caused the controller to disable write-back cache as a safety precaution against data corruption during power events.
RAID 5 requires all member disks operational to maintain parity redundancy, while controllers force write-through mode when memory protection battery modules fail.
2
Restore storage redundancy.
Remove the failed drive in slot 2 while the system is running (hot-swap) and insert an equivalent or larger SAS SSD to trigger or allow an automated RAID rebuild.
Hot-swapping allows drive replacement without taking the rest of the array down, re-establishing parity protection.
3
Restore storage write performance.
Replace the degraded battery backup unit on the hardware RAID controller.
A functional battery backup unit guarantees that unwritten cache memory is preserved during unexpected power losses, allowing write-back cache mode to be safely reactivated.

Cevabı ve açıklamayı göster

Cevap: Inspect or replace the display's inverter board or backlight power cable connecting the panel to the motherboard.; Provide the newly installed cellular modem's unique IMEI number to the mobile service provider to update device provisioning.

Cevap

The correct responses are to inspect or replace the display's backlight inverter/power connection, and to update the mobile carrier account with the newly installed cellular card's IMEI number.
The faint image symptom visible only under external lighting demonstrates that the LCD panel and graphics subsystem are rendering video, but the display backlight mechanism (inverter board or backlight cable) has failed. Additionally, cellular network operators authenticate devices based on the physical International Mobile Equipment Identity (IMEI) of the internal modem module; replacing the module requires updating the IMEI registered on the carrier account.

Adım Adım Çözüm

1
Diagnose the faint LCD image symptom.
Confirming image faintness under direct light indicates functional graphics processing and liquid crystal alignment, but a failed backlighting component such as the inverter or cable.
LCD screens require an explicit backlight circuit (inverter/driver or power feed) to illuminate rendered images.
2
Diagnose the WWAN cellular network registration failure after card replacement.
Identify that replacing the physical cellular module assigns a new hardware device identifier (IMEI) to the system.
Carriers bind network access to specific cellular device hardware identifiers (IMEI); swapping the hardware module requires registering the new IMEI with the service provider.

The server RAID 1 volume is degraded because Disk 1 has suffered a hardware failure.
RAID 1 mirrors data across two disks, allowing the array to remain functional on one drive during a single-disk failure.
2
Remove the failed drive and insert a replacement drive
A fresh, healthy drive of matching or higher capacity is seated in the drive bay.
The replacement disk must be at least as large as the original drive to mirror the volume contents properly.
3
Initiate the RAID rebuild process
Data from the surviving drive is copied onto the new drive, returning the RAID status to optimal.
Rebuilding synchronizes the mirror and reinstates fault tolerance.

Cevabı ve açıklamayı göster

Cevap: OLED displays produce light at the individual pixel level and do not use a backlight or inverter board.

Cevap

OLED displays produce light at the individual pixel level and do not use a backlight or inverter board.
OLED (Organic Light-Emitting Diode) displays feature self-emissive pixels. Because each pixel emits its own illumination, OLED screens do not utilize a backlight assembly or a high-voltage fluorescent inverter board. Therefore, attempting to replace an inverter board on an OLED screen is fundamentally incorrect.

Identify the display technology used by the mobile device
The laptop uses an Organic Light-Emitting Diode (OLED) display.
Display components differ depending on whether the screen is LCD or OLED.
2
Analyze how OLED screens generate light compared to traditional LCD screens
OLED pixels emit their own light when energized, requiring no backlight or inverter board.
Inverter boards were required in older CCFL LCD screens to convert DC power to high-voltage AC power for the backlight.
3
Determine the appropriate troubleshooting conclusion
Replacing an inverter board is impossible because the hardware component does not exist in an OLED display.
Technicians must recognize display architecture before attempting component replacement.

Cevabı ve açıklamayı göster

Cevap: A duplex mismatch between the workstation network card and the switch port

Cevap

A duplex mismatch between the workstation network card and the switch port
A duplex mismatch occurs when one end of an Ethernet link operates in full-duplex mode while the other operates in half-duplex mode. The full-duplex side transmits packets without checking for carrier sense, causing the half-duplex side to detect collisions mid-transmission (late collisions) and report frame alignment errors, leading to severe throughput degradation.

Adım Adım Çözüm

1
Analyze reported network symptoms
Local subnet connectivity is functional, but transfer speeds are abnormally low (<10 Mbps on a 1 Gbps link).
Identifies that physical layer link is established, but data link operations are failing under load.
2
Evaluate switch interface diagnostic logs
High count of late collisions and alignment errors detected.
Late collisions occur when one side transmits under the assumption of full-duplex (no CSMA/CD checking) while the connected peer operates in half-duplex (listening for collisions).
3
Match diagnostic errors to root cause
A speed/duplex mismatch between Ethernet endpoints causes late collisions and degraded throughput.
Correcting speed and duplex settings to match on both ends (or enabling auto-negotiation on both sides) resolves late collision errors.

Cevap: Replace Disk 0 with an equivalent replacement drive and initiate an array rebuild.

Cevap

Replace Disk 0 with an equivalent replacement drive and initiate an array rebuild.
Replacing the failing disk and allowing the controller to rebuild the mirror is the correct procedure for a degraded RAID 1 array. Because RAID 1 maintains an exact duplicate of the volume on the second drive, data remains fully accessible and redundancy can be restored by replacing only the compromised drive.

Adım Adım Çözüm

1
Identify drive status
Disk 0 is marked with a predictive S.M.A.R.T. failure while Disk 1 remains fully functional in a degraded RAID 1 state.
RAID 1 mirrors data across two drives, meaning Disk 1 contains a complete, functional copy of all data.
2
Determine corrective procedure
Hot-swap or replace Disk 0 with a drive of equal or greater capacity.
Replacing the failing hardware prevents total array failure before Disk 0 experiences complete physical failure.

Cevap: The array is degraded but operational; replace the failed drives one at a time and allow the controller to rebuild each mirrored pair from the surviving disks.

Cevap

The array is degraded but operational; replace the failed drives one at a time and allow the controller to rebuild each mirrored pair from the surviving disks.
RAID 10 (1+0) combines mirroring and striping. It creates mirrored pairs and stripes data across those pairs. In a four-drive array with Pair 1 (Drives 0 & 1) and Pair 2 (Drives 2 & 3), a loss of one disk in Pair 1 (Drive 0) and one disk in Pair 2 (Drive 3) leaves Drive 1 and Drive 2 containing complete copies of all striped data. The array remains in a degraded state, and replacing the failed drives allows the controller to rebuild redundancy without losing data.

Adım Adım Çözüm

1
Analyze the RAID 10 structure and disk distribution
RAID 10 consists of mirrored sets striped together. Pair 1 contains Drive 0 and Drive 1; Pair 2 contains Drive 2 and Drive 3.
Understanding which disk belongs to which mirrored set determines whether redundant copies of data remain accessible.
2
Evaluate the impact of the multi-drive failure
Drive 0 failed in Pair 1 (leaving Drive 1 operational). Drive 3 failed in Pair 2 (leaving Drive 2 operational).
Since no single mirrored pair lost both of its disks, 100% of the volume's data remains readable from the surviving disks (Drive 1 and Drive 2).
3
Determine the proper recovery workflow
Hot-swap the failed drives individually and permit the hardware controller to rebuild redundancy for Pair 1 and Pair 2.
Replacing disks sequentially prevents overloading drive I/O and restores full fault tolerance without downtime or data destruction.

Cevabı ve açıklamayı göster

Cevap: The client workstation was unable to communicate with a DHCP server and generated an APIPA address.

Cevap

The client workstation was unable to communicate with a DHCP server and generated an APIPA address.
An IPv4 address beginning with 169.254.x.x (with subnet mask 255.255.0.0) signifies an Automatic Private IP Addressing (APIPA) self-assignment. This occurs when a DHCP client requests an IP lease but receives no response from any local or relay DHCP server. Because APIPA does not configure a default gateway, communication is limited strictly to local subnet hosts.

Cevap: Local Users and Groups; Disk Management

Cevap

The tools integrated into the Computer Management console for managing user accounts and storage drives are Local Users and Groups and Disk Management.
Computer Management (`compmgmt.msc`) consolidates several Microsoft Management Console (MMC) snap-ins into a single tool interface. Local Users and Groups (located under System Tools) provides local account and group administration, while Disk Management (located under Storage) provides volume partitioning and formatting tools.

Cevap: Establish a plan of action to resolve the issue and implement the solution.

Cevap

Establish a plan of action to resolve the issue and implement the solution.
In the standard CompTIA 6-step troubleshooting methodology (1. Identify problem, 2. Establish theory of probable cause, 3. Test theory to determine cause, 4. Establish plan of action & implement solution, 5. Verify full system functionality & implement preventive measures, 6. Document findings, actions, and outcomes), the technician has completed Step 3 by testing and confirming the theory. Therefore, the immediate next step is to establish a plan of action to resolve the problem and implement the solution.

Adım Adım Çözüm

1
Identify the troubleshooting stage completed in the scenario.
The technician completed Step 3 (testing the theory to determine the confirmed cause).
The scenario specifies that the technician successfully tested the hypothesis and confirmed the root cause (an expired VPN client certificate).
2
Determine the next sequential step in the CompTIA 6-step troubleshooting methodology.
Step 4 is 'Establish a plan of action to resolve the problem and implement the solution'.
Following theory confirmation, the technician must design and execute a plan to apply the fix (e.g., renewing/installing the valid VPN certificate).
