SK0-005 CLI Questions — 20 Questions

Question 1

Your organization is migrating a Windows Server 2019 file server with 2 TB of shared data to a new server running Windows Server 2022. The migration must minimize user downtime and ensure file permissions are preserved. Users access files during business hours (8 AM to 6 PM) and the migration must be completed within a four-hour window starting at 10 PM on Saturday. You plan to use DFS Replication (DFSR) for initial data copy and then perform a final synchronization during the cutover. After setting up DFSR between the old and new servers, you realize that the initial replication will take approximately 12 hours due to the large number of files. What should you do to complete the migration within the allowed window?

Accepted Answer

Use robocopy to pre-stage the data from old to new server during off-hours before the cutover, then enable DFSR to replicate only changes made after pre-staging; during the cutover window, do a final DFSR sync. Option C is correct because pre-staging data using robocopy with appropriate flags (copying security and attributes) and then enabling DFSR for the delta changes is a best practice for large migrations. Option A is wrong because simply increasing DFSR bandwidth does not reduce the time needed for initial replication of 2 TB. Option B is wrong because using robocopy alone during the cutover window may not complete within four hours if you need to copy all data; pre-staging is required. Option D is wrong because performing a full backup and restore during the window is too time-consuming for 2 TB.

Answer

Disable DFSR and use robocopy with /MIR /COPYALL during the cutover window to copy all data

Answer

Perform a full backup of the old server and restore to the new server during the cutover window using Windows Backup

Answer

Increase the DFSR staging quota and bandwidth throttling to accelerate initial replication

Question 2

A company has a virtualized server environment with two physical hosts running VMware vSphere. Each host has 2 CPUs, 128GB RAM, and 6x 600GB SAS drives in RAID 10. Recently, host A experienced a power surge that caused it to shut down abruptly. After restarting, the host boots but the RAID controller reports that one of the drives in the RAID 10 array is missing. The administrator has a replacement drive of the same model. What should the administrator do first?

Accepted Answer

Check the RAID controller logs to determine if the drive is faulty or if it's a connection issue, and then reseat the drive or replace cables before replacing. The most appropriate first step is to troubleshoot the connection. The drive might be loose or the cable damaged due to the surge. Option C is correct because reseating or checking cables is non-invasive and could resolve the issue without replacing a working drive. Option A is incorrect because replacing immediately might be unnecessary if the drive is fine. Option B is incorrect because setting as hot spare won't help if the drive is not detected. Option D is incorrect because rebuilding the entire array is drastic and risks data loss.

Answer

Use the RAID controller utility to set the new drive as a hot spare and then reboot

Answer

Replace the missing drive with the new one and allow the RAID controller to automatically rebuild

Answer

Rebuild the entire RAID array after backing up data from the surviving drives

Question 3

You are a server administrator at a mid-sized company that hosts its own on-premises Exchange server and file server. The infrastructure consists of three racks: Rack A contains the core switches and firewalls, Rack B contains the Exchange server (Dell PowerEdge R740) and the file server (HP ProLiant DL380 Gen10), and Rack C contains backup devices and a tape library. The data center cooling is provided by a raised-floor system with perforated tiles. Recently, the file server has been experiencing random shutdowns during peak usage hours (10 AM to 2 PM). The shutdowns are preceded by system event log warnings indicating that the CPU temperature has exceeded the threshold. The ambient temperature around the rack is 20°C (68°F) as measured by a handheld thermometer. Other servers in Rack B do not exhibit this behavior. The file server is a 2U server with two Xeon processors, 128 GB RAM, and six hot-swap SATA drives. It runs Windows Server 2019. The server has been in service for three years with no prior issues. The data center manager has noted that the perforated tiles are clear of obstructions. You have verified that the fans in the file server are spinning and the internal air filters are clean. Which of the following is the MOST likely cause of the overheating issue?

Accepted Answer

The perforated tile under the file server has insufficient airflow due to cable blockage below the raised floor.. Option B is correct because the file server's shutdowns occur during peak hours when cooling load is highest. If the server is located in a spot with inadequate underfloor airflow (e.g., a tile blocked by cables or a misaligned tile), it will not receive enough cool air, leading to CPU overheating despite the ambient reading. Option A is incorrect because the fans are verified to be spinning and filters clean. Option C is unlikely because the ambient is normal and other servers are fine. Option D is possible but not as specific to peak hours; a failing PSU usually causes power loss, not CPU thermal events.

Answer

The ambient temperature sensor in the data center is reporting incorrectly and the actual temperature is higher.

Answer

The internal fans are not operating at full speed due to a failed fan controller.

Answer

The file server's power supply is failing and causing voltage drops that affect fan performance.

Question 4

A company operates a Windows Server 2019 machine that functions as a domain controller and file server. Over the past week, the server has randomly rebooted several times, often during periods of heavy file access. The administrator reviews the System event log and finds multiple Event ID 41 (Kernel-Power) entries with no preceding critical errors. The server is connected to an uninterruptible power supply (UPS) that reports stable input voltage. The server room temperature sensors indicate normal ambient temperature (22°C / 72°F). The server hardware is three years old and has not had any recent changes. The administrator has already run a full antivirus scan with no threats found. Which of the following should the administrator do NEXT to diagnose the issue?

Accepted Answer

Inspect and clean the CPU and chassis fans, and check for dust buildup. Option C is correct because random reboots with Kernel-Power 41 often indicate overheating due to failing fans or dust buildup, even if ambient temperature is normal. Option A is wrong because the power supply is likely not the issue given the UPS stability. Option B is wrong because a BIOS update is unlikely to solve hardware overheating. Option D is wrong because disabling automatic restart only hides the symptom and does not prevent the reboots.

Answer

Update the server's BIOS to the latest version

Answer

Replace the power supply unit

Answer

Disable the automatic restart feature in System Properties

Question 5

A company is migrating a legacy line-of-business application from Windows Server 2012 R2 to a new Windows Server 2022 server that is a member of an Active Directory domain. The application runs as a Windows service under a domain service account named CORP\svc_app. The service account has been granted the 'Log on as a service' user right on the old server, and the application is configured to listen on a static TCP port 8443. After installing the application on the new server and configuring it with the same service account and port, the application fails to start. The administrator checks the Windows Event Viewer and sees two errors in the System log: 'The CORP\svc_app service failed to start due to the following error: The service did not start due to a logon failure' and 'The service cannot bind to the designated port 8443'. The administrator has already verified that the service account's password is correct and has not expired, that the account is enabled, that the port 8443 is not being used by another service, and that the Windows Firewall has an inbound rule allowing traffic on port 8443. The application's configuration file correctly points to port 8443. What should the administrator do to resolve the issue?

Accepted Answer

Grant the 'Log on as a service' user right to the CORP\svc_app account via Local Security Policy or Group Policy.. The correct answer is B. The 'Log on as a service' user right is a security policy setting that must be explicitly assigned to a service account on each individual server. Even though the account had this right on the old server, it does not automatically carry over to the new server. Without this right, the service cannot start, and the 'logon failure' error is a classic symptom. Option A is incorrect because the password was already verified as correct. Option C is incorrect because the application requires a static port (port 8443) and changing to a dynamic port would break client connectivity. Option D is incorrect because restarting the server does not assign the missing user right and will not resolve the logon failure.

Answer

Restart the Windows Server 2022 server to apply any pending policy changes.

Answer

Configure the application to use a dynamic port instead of the static port 8443.

Answer

Reset the service account password and update the service configuration.

Question 6

A medium-sized company uses a backup strategy that includes a full backup every Sunday at 2:00 AM and differential backups Monday through Saturday at 2:00 AM. The backups are written to a network-attached storage (NAS) device. On Thursday morning, the company experiences a ransomware attack that encrypts all data on the file server, including the NAS. The administrator needs to restore the file server with minimal data loss. The last successful full backup was from the previous Sunday, and differential backups were successful on Monday, Tuesday, and Wednesday. However, Thursday's differential was not completed because the attack occurred before the scheduled time. The administrator attempts to restore using the Sunday full backup and Thursday's differential, but the restore fails because the differential backup on the NAS is also encrypted. Which of the following is the best course of action?

Accepted Answer

Restore from the Sunday full backup and Wednesday's differential backup. The most recent clean backup set is Sunday's full plus Wednesday's differential, as both were taken before the ransomware attack. Restoring from these will recover data as of Wednesday's backup, minimizing data loss. Using only Wednesday's differential requires the full backup first. Paying the ransom is not recommended and may not work. Reinstalling the OS and restoring from cloud would not apply because cloud was not mentioned.

Answer

Pay the ransom to decrypt the differential backup

Answer

Reinstall the operating system and restore files from cloud storage

Answer

Restore using only Wednesday's differential backup

Question 7

A small business has a single file server running Windows Server 2019. The server uses two internal SATA drives in a RAID 1 mirror for the operating system and data. The company's backup solution performs a full backup every night to an external USB hard drive, which is stored in the server room. The IT administrator recently noticed that the server's system volume is running low on space and decides to migrate the data to a larger drive. During the migration, the server crashes and will not boot. The administrator attempts to restore from the latest backup but finds that the backup drive is corrupted and cannot be read. The company has no offsite backups. What should the administrator have done to prevent this situation?

Accepted Answer

Regularly test backup restorations to verify data integrity.. The correct answer is D: Regularly test backup restorations to verify data integrity. The administrator assumed backups were valid without verification. Option A is wrong because RAID 1 provides redundancy but does not protect against corruption or accidental deletion; the issue here is backup corruption. Option B is wrong because cloud backup is a good practice but not strictly required; the root cause is lack of backup testing. Option C is wrong because while documentation is helpful, it would not prevent data loss from a corrupted backup drive.

Answer

Implement a RAID 5 array instead of RAID 1 for better redundancy.

Answer

Document the backup procedure and create a disaster recovery plan.

Answer

Use a cloud-based backup service with offsite storage.

Question 8

A medium-sized company runs an e-commerce platform on a cluster of three physical servers hosting virtual machines. The disaster recovery plan includes daily backups to a remote data center using Veeam Backup & Replication. The company's annual disaster recovery drill is scheduled for next week. During the drill, the IT team plans to simulate a complete site failure by powering off the primary data center. The recovery time objective (RTO) is 4 hours, and the recovery point objective (RPO) is 1 hour. The team successfully restores the VMs at the remote site, but the application experiences significant performance degradation and many transactions fail due to database inconsistency. Investigation reveals that the backup was taken at 2:00 AM, but the failure occurred at 10:00 AM, and the application's database had transactions between 2:00 AM and 10:00 AM that were not captured. What should the IT team do to improve the recovery process?

Accepted Answer

Enable log shipping with point-in-time recovery for the database.. The correct answer is B: Implement log shipping with point-in-time recovery for the database. The RPO of 1 hour is not being met because the backup schedule is daily. Option A is wrong because while a faster WAN can reduce backup time, the core issue is the backup frequency, not bandwidth. Option C is wrong because the issue is not data redundancy but recovery granularity; RAID protects against drive failure but not data loss from missing transactions. Option D is wrong because increasing RTO does not solve the RPO violation; the goal is to reduce data loss, not relax the time target.

Answer

Configure RAID 10 on all database servers to improve disk performance.

Answer

Upgrade the WAN connection between sites to reduce backup transfer times.

Answer

Adjust the RTO to 8 hours to allow for more comprehensive backups.

Question 9

A large enterprise uses a centralized backup solution with a backup server running Commvault. Backups are stored on a deduplicated disk array and replicated to a secondary site for disaster recovery. The company's security team detects ransomware activity that has encrypted several file servers. The backup administrator checks the backup repository and finds that the backup data is also encrypted because the backup service account had permissions to modify backup files, and the ransomware propagated to the repository. The last known good backup is from two weeks ago, which is too old for the organization's RPO of 24 hours. The backup administrator is under pressure to restore operations quickly. Which of the following should the administrator implement to prevent this from recurring?

Accepted Answer

Immutable backup storage and a dedicated service account with least-privilege access.. The correct answer is A: Implement immutable backup storage and use a separate service account with write permissions only during backup windows. Immutable backups cannot be modified or deleted by any user or process, including ransomware. Option B is wrong because air-gapping alone does not prevent access if the backup server is compromised; immutable storage is more robust. Option C is wrong because while MFA is a good security practice, it does not protect backups that are already accessible with valid credentials. Option D is wrong because encryption of backup data protects it during transit or while stored, but does not prevent the ransomware from encrypting the files if the backup system is accessible.

Answer

Encrypt all backup data at rest and in transit.

Answer

Require multi-factor authentication for the backup service account.

Answer

Air-gap the backup repository by disconnecting it from the network except during backup windows.

Question 10

You are a server engineer for a financial services firm. The company recently deployed a new HP ProLiant DL380 Gen10 server running Windows Server 2022 with SQL Server 2019. The server has 2 Intel Xeon Gold processors, 128GB RAM, and a Smart Array P408i-p controller managing two RAID 1 arrays: one for OS (two 300GB 10K SAS) and one for data (four 600GB 10K SAS). After one month, the OS array reports a predictive failure on one drive. You replace the drive via hot-swap, and the RAID controller rebuilds. However, the server now experiences random system crashes with Event ID 1001 (BugCheck) and the SQL database occasionally becomes corrupt requiring restore from backup. The server's RAM has been tested with HP's diagnostic tool and passed, and the CPU temperature is normal. The RAID controller log shows no errors during the rebuild but occasional 'Parity errors' logged before the drive replacement. Which of the following is the MOST likely cause of the current instability?

Accepted Answer

The remaining original OS drive has bad sectors that were not detected.. Option C is correct because predictive failure on one drive may indicate that the entire mirrored pair has latent defects; the remaining original drive may have bad sectors that were not detected. The parity errors before replacement suggest data inconsistency, and after rebuild, the system relies on the remaining drive which can cause crashes and database corruption. Option A is wrong because the rebuild completed without errors, so the new drive is likely fine. Option B is wrong because a failed cache module would cause general errors, not specific parity issues. Option D is wrong because a faulty PCIe slot would cause intermittent disconnects of the controller, not these symptoms.

Answer

The new replacement drive is faulty.

Answer

The motherboard has a faulty PCIe slot for the RAID controller.

Answer

The RAID controller cache module has failed.

Question 11

A data center technician is troubleshooting a server that is overheating and shutting down intermittently. The server is a 2U rackmount with six fans at the front and a power supply with an integrated fan at the rear. The technician checks the ambient temperature (72°F) and verifies that the server intake temperature is normal. The server's system logs show 'CPU temperature threshold exceeded' before each shutdown. The technician has replaced the thermal paste on the CPU and reseated the heat sink, but the issue persists. Which of the following should the technician do NEXT?

Accepted Answer

Replace the chassis fans with high-static-pressure models. Option B is correct: the fans may be running but not at full speed due to a faulty fan controller or sensors. Option A is wrong because ambient temp is fine. Option C is wrong because CPU is already reseated. Option D is wrong because power supply is not indicated.

Answer

Move the server to a cooler location in the data center

Answer

Reinstall the CPU heat sink with more thermal paste

Answer

Replace the power supply unit

Question 12

A server administrator is assembling a new high-performance server using a Supermicro X12 motherboard, two Intel Xeon Gold 5317 processors (LGA 4189 socket), and 16x 32GB DDR4-3200 ECC LRDIMMs for a total of 512GB of memory. The chassis has redundant 1600W power supplies. After assembling all components, the administrator powers on the server. All fans start spinning at full speed, and the front panel LEDs illuminate. However, the server does not POST, there are no beep codes, and no video output is displayed. The motherboard has a two-digit hexadecimal POST code LED display, which shows '00' and does not change. The motherboard manual states that code '00' indicates the CPU is not detected or has failed. The processors are confirmed to be the correct socket type and stepping as required by the motherboard. What should the technician do FIRST?

Accepted Answer

Reseat both processors and inspect the CPU sockets for bent pins. Option B is correct. The POST code '00' typically indicates a CPU initialization failure. The first and least invasive step is to reseat the processors, checking for bent socket pins, debris, or improper mounting. This resolves a majority of such issues. Option A (replace both CPUs) is extreme and should only be done after ruling out physical installation issues. Option C (clear CMOS) may help if the BIOS was misconfigured for a previous CPU, but physical reseating is more direct. Option D (update BIOS) is not possible if the system cannot POST to enter the update utility; furthermore, if the CPUs are supported by the current BIOS version, updating is unnecessary.

Answer

Replace both processors as they are likely faulty

Answer

Clear the CMOS using the jumper or button on the motherboard

Answer

Update the BIOS to the latest version using the IPMI interface

Question 13

A small business relies on a tower server that acts as a file and print server for 15 employees. The server has a single Intel Xeon E-2300 series processor, four 16GB DDR4 ECC RDIMMs installed in dual-channel configuration, and two 2TB 7200 RPM SATA hard drives in a hardware RAID 1 mirror. The power supply unit (PSU) is a 500W 80+ Bronze unit that is about four years old. Recently, the server has started experiencing random, intermittent crashes resulting in a blue screen, typically during periods of heavy disk I/O, such as when multiple users access large files. Event Viewer logs show occasional corrected memory errors (ECC events) but no uncorrected errors. The administrator runs MemTest86+ on all four DIMMs for multiple passes, and no errors are detected. The server room ambient temperature is normal, and all fans are operating. The crashes are becoming more frequent. Which of the following actions would MOST likely resolve the underlying issue?

Accepted Answer

Upgrade the power supply to a higher wattage, 80+ Gold unit. Option B is correct. Intermittent crashes under heavy load, combined with ECC corrected errors but passing memory tests, can indicate a power supply that is failing or inadequate under peak load. A 500W PSU may be marginal, especially with aging capacitors, causing voltage drops that lead to memory and system instability. Option A: Replacing the motherboard is premature, as no clear evidence points to a faulty memory controller. Option C: Reseating RAM may help if a connection issue, but given MemTest passes and errors are corrected, physical seating is less likely. Option D: Replacing HDDs with SSDs would reduce I/O load but does not address the likely power instability causing memory errors and crashes.

Answer

Reseat all memory modules and clean the DIMM slots

Answer

Replace the hard drives with solid-state drives (SSDs)

Answer

Replace the motherboard, as the memory controller is likely failing

Question 14

A small business has purchased a new server to function as a file server for 25 employees. The server is equipped with four 1TB SATA hard disk drives and no hardware RAID controller; the operating system supports software RAID. The business owner's primary requirements are data redundancy to protect against a single drive failure and maximum usable storage capacity, while keeping costs low. The IT technician is tasked with configuring the storage. The technician evaluates the following options: RAID 0 striping across all four drives; RAID 1 mirroring using two pairs (drives 1+2 mirrored, drives 3+4 mirrored), providing two separate volumes; RAID 5 with parity across all four drives; and RAID 10 combining mirroring and striping. The technician needs to recommend the configuration that best meets the requirements. Which of the following should the technician implement?

Accepted Answer

Configure RAID 5 to stripe data and parity across all four drives, providing 3TB of usable storage with single-drive fault tolerance.. Option C is correct because RAID 5 provides single-drive fault tolerance and maximizes usable capacity (3TB out of 4TB), offering the best balance between redundancy and storage space. Option A provides no redundancy. Option B uses mirroring, which wastes half the total capacity (only 2TB usable). Option D also provides only 2TB and adds performance benefits that are not the primary requirement, while costing more in usable space.

Answer

Configure RAID 10 by mirroring two pairs and striping across them, providing 2TB of storage with high performance and redundancy.

Answer

Configure RAID 0 to stripe across all four drives for maximum 4TB storage and performance.

Answer

Configure RAID 1 with two mirrored pairs, providing 2TB of total storage across two volumes, ensuring redundancy.

Question 15

A server administrator receives reports that a production server is shutting down unexpectedly after running for several hours. The server is a 2U rackmount unit located in a data center with proper ambient cooling (20°C/68°F). The server has redundant power supplies connected to separate PDUs and no power anomalies are reported. The administrator checks the operating system event logs and finds a critical log entry: 'The system was shut down due to a thermal event.' However, the CPU temperature logs show that the CPU was at 47°C at the time of shutdown, and the chassis inlet temperature was 23°C. The server's internal fans are running at high speed and are clearly audible. The administrator suspects a thermal issue but is unsure why the CPU is not showing high temperature. The server has a baseboard management controller (BMC) that monitors various sensors. Which of the following components should the administrator investigate FIRST to identify the likely cause of the shutdown?

Accepted Answer

Inspect the voltage regulator module (VRM) temperatures and airflow around the motherboard.. Option B is correct because voltage regulator modules (VRMs) can overheat and trigger a thermal shutdown via the BMC even when the CPU temperature is within normal limits. VRMs are often located in areas with restricted airflow and are critical to CPU power delivery. Option A is incorrect because CPU temperature is normal, so the heatsink is likely functioning. Option C is incorrect because power supply faults would not generate a thermal event. Option D is a possible long-term fix for a firmware bug, but physical inspection of temperature-sensitive components should come first.

Answer

Swap the redundant power supplies to rule out a failing PSU.

Answer

Replace the CPU heatsink and reapply thermal paste.

Answer

Update the server firmware and BIOS to the latest version.

Question 16

A company is expanding its data center to support a new four-node database cluster for a critical application requiring 99.999% uptime, meaning only minutes of downtime per year. Each server node has dual 1000W power supplies. The facility provides two independent power feeds from separate utility substations, each backed by its own online double-conversion UPS. There are four 20A/208V PDUs available, two per power feed. The design must ensure that the loss of any single power feed, any single UPS, or any single PDU does not cause any server to lose power or impact the cluster's availability. The servers are located in a single rack, and cabling must follow best practices for manageability and airflow. The IT architect is evaluating different power distribution strategies to meet these fault-tolerance requirements. Which of the following configurations achieves full redundancy with no single point of failure in the power path?

Accepted Answer

Connect the first power supply of each server to a PDU on power feed A and the second power supply to a PDU on power feed B.. Option D is correct because connecting each server's power supplies to two different PDUs that are on separate power feeds guarantees that if one feed, UPS, or PDU fails, the server continues to receive power from the remaining source. Option A does not protect against PDU failure. Option B exposes servers to a power feed failure. Option C introduces a single PDU as a single point of failure.

Answer

Connect each server's power supplies to two PDUs that are both on the same power feed, and use the second feed only as a cold standby in case of a primary feed failure.

Answer

Connect each server's power supplies to the same PDU, but distribute servers across the four PDUs for load balancing.

Answer

Use a single large PDU with dual inputs from both feeds and an automatic transfer switch, connecting all servers to that PDU.

Question 17

A small business plans to deploy a new on-premises server for a virtualization environment. The server will run a hypervisor hosting four virtual machines: a domain controller, a file server, a web application server, and an SQL database server. The business expects moderate workloads and needs to ensure reliable performance and data protection. The procurement department has proposed the following server configuration: single Intel Xeon E-2300 series CPU (4 cores, 8 threads), 16 GB DDR4 ECC RAM, two 1 TB SATA hard drives configured in RAID 1, a single 1 GbE network interface, and a 500W power supply. The IT manager reviews the proposal and identifies several deficiencies that will not meet the expected workload requirements. Which of the following changes to the server configuration is the MOST important to address first to ensure the VMs can run effectively?

Accepted Answer

Increase the RAM to at least 32 GB to support the four VMs.. In virtualization, RAM is typically the first resource to become a bottleneck because each VM requires its own memory allocation. 16 GB is insufficient for four VMs, especially with an SQL database server, which often demands a large memory footprint. Option C is correct because increasing RAM to at least 32 GB allows the hypervisor to allocate adequate memory to each VM, preventing excessive swapping and performance degradation. Option A is incorrect because the proposed CPU (4c/8t) can handle moderate workloads if RAM is sufficient; more cores are secondary. Option B is incorrect because while SSDs and RAID 10 would improve disk I/O, the immediate showstopper is insufficient RAM, which would cause VMs to fail or thrash regardless of storage speed. Option D is incorrect because a single 1 GbE link might be adequate initially, and NIC teaming addresses redundancy, not the fundamental resource deficit.

Answer

Replace the SATA hard drives with SSDs and configure RAID 10 for better I/O performance.

Answer

Add a second 1 GbE network interface and configure NIC teaming for redundancy.

Answer

Upgrade the CPU to a model with at least 8 cores and 16 threads.

Question 18

A technician receives an urgent alert that a critical file server at a remote branch office has gone offline and is unreachable over the network. The server is accessible via out-of-band IPMI, which indicates that chassis power is present, but the power LED on the server is blinking amber instead of steady green. The IPMI system event log reports "System board voltage regulator failure" as the last critical event before the failure. Attempts to use the remote KVM show no video output, and Wake-on-LAN commands have no effect. The branch office has no on-site IT personnel; the only staff are general office workers with minimal technical training. The earliest a field technician can travel to the site is 48 hours. The main office has an identically configured spare server and a backup image of the file server's system disk. The branch office staff can follow simple plug-and-play instructions if provided. Which of the following is the BEST immediate course of action to restore the file services with minimal downtime?

Accepted Answer

Ship the spare server and a pre-configured backup image to the branch office for local staff to swap.. Given the voltage regulator failure on the system board, the server is not repairable remotely. Shipping the pre-configured spare server allows non-technical staff to swap the entire unit by following simple cabling instructions, restoring service quickly without waiting for a technician. Option A is correct because it minimizes downtime by leveraging available resources. Option B is incorrect because voltage regulator modules are rarely field-replaceable; they are integrated into the motherboard, and dispatching a technician would take 48 hours plus repair time. Option C is incorrect because reseating the power supply is unlikely to fix a system board voltage regulator fault, and could cause further confusion for untrained staff. Option D is incorrect because ordering a replacement board and waiting for a technician to install it would take even longer, extending downtime unnecessarily.

Answer

Order a replacement system board and express ship it to the branch for a technician to install later.

Answer

Instruct a non-technical employee at the branch to reseat the power supply and clear the error log.

Answer

Dispatch a technician with a replacement voltage regulator module for on-site repair.

Question 19

An administrator is monitoring a server that has a hardware RAID 5 array consisting of four 2 TB disks. The RAID controller's management software reports that one disk has a status of 'Pred Fail' (predictive failure). The array also has a dedicated hot spare disk already installed and set up. The array is still fully functional with no data loss, but the 'Pred Fail' warning indicates the disk is likely to fail soon. The server is a production database server that cannot be taken offline except for scheduled maintenance windows, which are not until the following weekend. The administrator needs to ensure data integrity and avoid any risk of downtime or data loss while waiting for the replacement. Which immediate action should the administrator take?

Accepted Answer

Use the RAID management software to initiate a proactive replacement of the pred fail disk with the hot spare. Option A is correct because replacing the failing disk with the hot spare proactively prevents the array from becoming degraded or failing if another disk fails, ensuring continuous protection. Option B is wrong because waiting risks catastrophic failure if another disk fails before the spare activates. Option C is wrong because a full backup is not a substitute for immediate redundancy restoration. Option D is wrong because removing the disk from the array manually would degrade it and risk data loss if another disk fails during the rebuild.

Answer

Wait for the disk to completely fail so that the hot spare will automatically rebuild the array

Answer

Take a full backup immediately and then replace the disk during the next maintenance window

Answer

Remove the pred fail disk from the array to force the hot spare to rebuild, then re-add the disk later

Question 20

A medium-sized business runs a critical internal application on a single physical server running Windows Server 2019. The application is memory-intensive, often using up to 24 GB out of 32 GB RAM during peak hours. Over the past week, the server has experienced three unexpected reboots, each occurring during peak load. The server is not part of a cluster, and all data is stored on local disks. You have checked the Windows System event log and found Event ID 41 (Kernel-Power) indicating an unexpected shutdown. There are no related critical errors in the Application log. You have also reviewed the server's firmware logs and found multiple corrected memory errors (ECC) over the last month, with an increase in frequency just before each crash. The server is under warranty, and the hardware vendor's diagnostic tools report a failing memory module in DIMM slot A1. The vendor has recommended replacing the faulty DIMM immediately. However, the server is currently processing critical end-of-quarter financial reports that cannot be interrupted for at least 6 hours. Which of the following is the BEST course of action to minimize risk of data loss and downtime until a planned maintenance window?

Accepted Answer

Inform management of the criticality, request emergency approval for immediate maintenance, and if denied, ensure current backups are verified and monitor the server closely for any signs of degradation until the maintenance window.. Option D is correct because it follows proper change management: informing stakeholders, seeking emergency approval if needed, and mitigating risk by verifying backups and monitoring. Option A is wrong because immediately shutting down would interrupt critical processing and potential data loss, without management approval. Option B is wrong because Windows Memory Diagnostic is a boot-time tool and cannot effectively isolate memory regions to avoid crashes on a running production system. Option C is wrong because the server has already crashed, indicating uncorrectable errors; continuing without action risks data corruption and further unplanned outages.

Answer

Use Windows Memory Diagnostic tool to try to isolate the memory region and prevent the application from using it.

Answer

Continue running the server as is, as ECC memory can correct errors and the server will only crash if errors are uncorrectable; the risk is low.

Answer

Immediately shut down the server, replace the faulty DIMM, and restart.
