Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct configuration sequence is: 1) Create the target shared folder on the network file server and assign write permissions to a dedicated scanner service account, 2) Open a web browser on a management workstation and enter the MFD's static IP address to access its Embedded Web Server (EWS), 3) Authenticate to the Embedded Web Server using administrator credentials, 4) Navigate to the digital sending/scan settings menu and input the target UNC path, domain network credentials, and authentication details, and 5) Initiate a test scan directly from the MFD touchscreen control panel to confirm successful file delivery to the network destination.
Configuring Scan-to-SMB requires server-side setup before hardware-side setup. First, the destination folder and access control permissions must be established on the server. Next, the technician accesses the MFD management interface by navigating to its IP address in a browser and authenticates with administrator credentials. After logging in, the technician enters the UNC path and account details into the SMB scan configuration section. Finally, conducting a test scan from the device control panel confirms that all permissions and network connections are correctly configured.

CompTIA 6-Step Troubleshooting Methodology
Soru 23Soru →

A network technician is troubleshooting a desktop computer that has lost network access. Following a bottom-up (physical to application layer) troubleshooting approach, in what order should the technician perform the diagnostic steps?

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct order follows a bottom-up diagnostic sequence: first verify the physical link light and cable, next check the workstation IP configuration with ipconfig, then ping the default gateway to test local network access, and finally run nslookup to verify DNS name resolution.
The bottom-up OSI troubleshooting model moves sequentially from Layer 1 (Physical) to Layer 7 (Application). Checking the physical cable and NIC link light comes first. Once physical connection is confirmed, verifying the local IP configuration (Layer 3) is next. Testing ICMP connectivity to the default gateway ensures local communication works before finally checking DNS hostname resolution at the application layer.

Adım Adım Çözüm

1
Verify physical layer connectivity.
Ensure the physical cable is securely attached and the NIC link light indicates an active connection.
Troubleshooting should start at the physical layer to confirm hardware connectivity before checking software settings.
2
Check protocol layer configuration.
Determine whether the host has a valid IPv4 address assigned via DHCP or a self-assigned 169.254.x.x APIPA address.
Verifying IP addressing ensures the device has valid network configuration settings.
3
Test local network routing.
Confirm whether ICMP packets can reach the default gateway router.
Pinging the gateway verifies local link integrity and subnet routing capabilities.
4
Test application service resolution.
Confirm whether fully qualified domain names (FQDNs) can be resolved to IP addresses.
DNS resolution represents high-level service functionality needed for web browsing and domain communication.

Cevabı ve açıklamayı göster

Cevap

The proper sequence to replace a failed drive in a hot-swappable RAID 5 array is: verify a valid data backup exists, identify the failed drive using software and LEDs, replace the faulty drive with a compatible unit, and monitor the RAID rebuild process until completion.
Standard CompTIA troubleshooting methodology requires prioritizing data safety first (verifying backups), correctly isolating the failed hardware component using diagnostic tools and status LEDs, physically replacing the failed component with compatible hardware, and confirming complete operational recovery by monitoring the rebuild process.

Adım Adım Çözüm

1
Verify current data backups
Protects against catastrophic data loss during array recovery operations.
RAID 5 can only sustain a single drive failure; if a second drive encounters errors during replacement, unbacked-up data will be unrecoverable.
2
Identify the faulty drive bay
Confirms the exact physical drive that has failed.
Pulling a functional drive from a degraded RAID 5 array breaks the array and causes total data loss.
3
Swap the failed drive
Replaces the dead hardware with a functional, equal-or-larger disk.
A healthy disk of appropriate size is required to store the reconstructed data blocks and parity.
4
Monitor array rebuilding
Verifies that parity reconstruction completes successfully.

Cevabı ve açıklamayı göster

Cevap

The correct sequence for recovering the degraded RAID 5 array is: 1) Identify the physical location of the failed disk, 2) Verify or execute a system data backup, 3) Remove the failed drive and insert a compatible replacement, 4) Initiate the array rebuild process, and 5) Monitor the rebuild progress until the status returns to Optimal.
The standard recovery procedure starts by identifying the specific failed physical disk to prevent removing an active disk. Next, performing or verifying a backup guards against catastrophic data loss if another disk fails while fault tolerance is down. After securing backups, hot-swapping the bad drive with a compatible unit prepares the array for data reconstruction. Initiating the rebuild recalculates parity data across the remaining drives onto the new disk. Finally, monitoring the array until its health status shows Optimal verifies that redundancy has been completely restored.

Adım Adım Çözüm

1
Identify the failed physical drive slot
Pinpoints the faulty disk without interrupting active drives
Prevents human error during physical maintenance.
2
Verify or create an array data backup
Secures data integrity against secondary drive failure
A degraded RAID 5 array has zero fault tolerance until rebuilt.
3
Replace the physical drive
Places functional hardware in the server bay
Physical installation must occur before parity data can be written.
4
Start the RAID rebuild operation
Parity recalculation begins writing to the new drive
The array controller must mathematically restore missing data chunks onto the target disk.
5
Verify final array status
Array health status changes from Degraded to Optimal
Confirms fault tolerance is re-established for normal operations.

In what chronological sequence should the technician perform the following steps to safely replace the failed drive and restore fault tolerance?

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct order of operations is: 1) Identify the specific faulty drive slot using the RAID management console and drive bay LED status indicators. 2) Verify the presence of a complete current backup of the array volume data. 3) Remove the failed drive from the hot-swap enclosure and install a replacement drive of equal or greater capacity. 4) Assign the new drive to the logical volume or trigger the array rebuild process in the RAID controller interface. 5) Monitor the rebuilding status until the RAID utility reports an Operational/Optimal state.
The correct procedural order ensures data safety and system integrity. First, identifying the failed drive bay via management software or physical LEDs prevents pulling an operational drive from a degraded array. Second, verifying or making a backup protects against catastrophic data loss if a secondary drive fails during the high-stress rebuild phase. Third, replacing the faulty drive with an appropriately sized spare physically fixes the broken hardware component. Fourth, assigning the new drive or triggering the rebuild in the RAID controller starts parity recalculation. Finally, monitoring the rebuild until completion guarantees that fault tolerance is restored.

The technician confirms the exact physical bay location of the failed disk.
Accurate identification prevents accidental removal of a functional drive, which would cause immediate catastrophic failure of a degraded RAID 5 array.
2
Verify or create a full volume data backup.
Critical data is safeguarded prior to heavy hardware rebuild operations.
Rebuilding parity subjects remaining operational disks to extensive read stress, elevating the likelihood of an unrecoverable read error (URE) or secondary drive failure.
3
Perform physical drive replacement.
The defective disk is replaced with a functional drive meeting hardware specifications.
The system requires a compatible, fully functioning disk with equal or greater storage capacity to restore array structure.
4
Initiate RAID array rebuild procedure.
The RAID controller software registers the replacement disk and begins background parity recalculation.
Physical replacement alone does not always start reconstruction unless assigned manually or configured as a hot spare.
5
Confirm complete rebuild and system redundancy.
The storage array status transitions from Degraded back to Optimal.
Ongoing verification ensures parity synchronization completes without error before returning the server to full production use.

Cevap

The correct procedural order is: first, perform a verified backup of the current RAID volume data; second, set the failing physical drive to an offline status using the RAID management utility; third, remove the failing drive from the drive bay and seat the compatible replacement drive; fourth, initiate the RAID volume rebuild process through the controller interface; fifth, monitor the rebuild progress until the volume status transitions back to Optimal.
The standard technician workflow for addressing predictive drive failures in hardware RAID arrays demands data protection prior to physical hardware manipulation. Creating a fresh backup protects against secondary drive failure. Taking the disk offline logically ensures clean separation from the controller. Physical drive replacement follows, after which initiating and monitoring the rebuild until status reaches Optimal completes the restoration of fault tolerance.

Adım Adım Çözüm

1
Execute a full, verified backup of the RAID 5 array.
Recent volume state is safely preserved on secondary storage.
RAID 5 can only sustain a single drive failure; backing up first mitigates catastrophic data loss if another disk encounters unrecoverable read errors during the rebuild.
2
Log into the RAID controller utility and set the predictive failure disk offline.
The controller logically unmounts the drive from the array.
Prevents OS/controller I/O hangs or data corruption during physical extraction.
3
Hot-swap the failing physical disk with a new disk of equal or greater capacity.
New blank drive is physically installed in the target bay.
Provides the physical medium required to accept parity reconstruction.
4
Assign the new drive as a hot spare or manually start the rebuild process in the utility.
The controller begins calculating parity and writing missing block data to the new drive.
Parity recalculation is necessary to reconstruct the data of the replaced drive.
5
Track rebuild logs until the array health returns to Optimal.
Volume redundancy is fully restored.
Ensures the rebuild process finishes without write failures or bad sectors.
