Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Run a full memory diagnostic such as memtest86+ or the vendor's offline diagnostics before replacement. Correctable memory errors climbing on one DIMM signal a degrading module that should be validated and replaced. Running offline diagnostics confirms the faulty part and checks the remaining modules, while replacing the DIMM during a maintenance window removes the root cause before errors become uncorrectable and threaten production. Suppressing, relocating, or overclocking the memory leaves the failing hardware in service.

Answer

Move the DIMM to a different slot and continue running without diagnostics

Answer

Increase the memory clock speed to improve error correction throughput

Answer

Disable ECC in the BIOS so the correctable errors stop being logged

Question 2

A server administrator needs to deploy a new physical server that will run a database requiring high availability and maximum performance. The server has four 1 TB NVMe SSDs. The administrator wants to configure RAID 10 for both redundancy and performance. Which of the following should the administrator do to achieve this?

Accepted Answer

Configure a hardware RAID 10 array using the RAID controller.. RAID 10 is the best choice for a database requiring high availability and maximum performance because it combines mirroring for redundancy and striping for performance. Hardware RAID offloads processing to a dedicated controller, further enhancing performance. The other RAID levels either lack redundancy (RAID 0) or have lower performance (RAID 5, RAID 6) for write-intensive workloads.

Answer

Configure a RAID 6 array using the NVMe drives.

Answer

Configure software RAID 5 using the operating system's disk management tools.

Answer

Configure a RAID 0 array using the NVMe drives.

Question 3

A server administrator is installing a new 2U rack server that will use four 960GB SATA SSDs in a hardware RAID 10 array for the operating system. The server's RAID controller supports both SATA and SAS drives. After physically installing the drives in the front bays, the administrator powers on the server but the RAID controller does not detect any drives. Which of the following is the MOST likely cause?

Accepted Answer

The drives are not properly seated in the backplane connectors.. The most likely cause is that the drives are not fully seated in the backplane connectors. In hot-swap bays, drives must be pushed firmly until they click. If not seated, the RAID controller sees no drives. Reseating is a simple first step before investigating firmware or configuration.

Answer

The power supply units are insufficient to power the SSDs.

Answer

The RAID controller firmware needs to be updated to support SATA SSDs.

Answer

The drives are not initialized in the RAID controller BIOS.

Question 4

A server administrator needs to deploy a new physical server that will host a database. The database requires high random read/write performance and redundancy. The server has a RAID controller that supports RAID 0, 1, 5, 6, and 10. The administrator installs four identical SAS SSDs. Which RAID level should the administrator configure to meet the performance and redundancy requirements?

Accepted Answer

RAID 10. RAID 10 offers the best combination of high random read/write performance and redundancy for a database server. It stripes data across mirrored pairs, allowing multiple simultaneous reads and writes while tolerating drive failures. Other RAID levels either lack redundancy (RAID 0) or have performance limitations for write-intensive workloads (RAID 1, RAID 5).

Answer

RAID 0

Answer

RAID 5

Answer

RAID 1

Question 5

A server technician is replacing a failed hot-swappable 2.5-inch SAS drive in a production 2U server while it remains powered on. The drive bay is populated and the array is in a degraded state. Which of the following should the technician do FIRST before physically removing the failed drive?

Accepted Answer

Identify the failed drive's bay location using the drive LED status indicators or the RAID controller management utility. Before touching a live array, the technician must positively identify the failed member's physical bay. Fault LEDs on the drive carrier or the controller's management interface map logical members to physical slots, preventing removal of a healthy drive that would push a degraded array into a failed state. Shutting down, deleting configuration, or checking performance specs do not address the immediate risk of removing the wrong component.

Answer

Verify the replacement drive has a higher spindle speed and larger cache than the failed unit

Answer

Shut down the server and place it in maintenance mode before opening the chassis

Answer

Delete the failed member from the RAID configuration to prevent rebuild conflicts

Question 6

A server administrator is configuring a Windows Server 2022 failover cluster with two nodes. The cluster will host a highly available file server role. The administrator needs to ensure that the file server role can fail over automatically if one node goes down. The cluster has shared storage presented as a single disk. Which of the following should the administrator configure to meet this requirement?

Accepted Answer

Add the file server role as a clustered role and ensure the shared disk is added as a resource in the role.. The correct configuration is to add the file server role as a clustered role and include the shared disk as a resource in that role. This ensures that the role and its storage are managed together and can fail over automatically to the other node if one fails. The cluster service handles the failover based on node health and quorum.

Answer

Configure the file server role to use a distributed network name and a scale-out file server.

Answer

Enable Cluster Shared Volumes (CSV) and place the file server role on the CSV.

Answer

Configure the file server role with a preferred owner and set the failover threshold to 1.

Question 7

A server administrator is troubleshooting a physical server that emits a continuous amber health LED and whose operating system logs show correctable memory errors increasing on one DIMM slot. The server is still running production workloads. Which of the following actions should the administrator take? (Choose two.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Capture a sector-level image of each affected disk before attempting any repair. When volumes unexpectedly appear as RAW after a controller firmware change, the priority is preserving the current disk state. A sector-level image captures everything before any write occurs, so repair, rollback, or third-party recovery can proceed safely. Repair tools, formatting, and even a firmware rollback all risk modifying the disks, so imaging must come first.

Answer

Immediately reformat the volumes as NTFS to restore service

Answer

Run chkdsk /f on each affected volume to repair the file system

Answer

Roll back the controller firmware and reboot to see if the volumes return

Question 8

A server administrator is troubleshooting a physical server that emits a continuous amber health LED and whose operating system logs show correctable memory errors increasing on one DIMM slot. The server is still running production workloads. Which of the following actions should the administrator take? (Choose two.)

Accepted Answer

iostat -x 2. iostat -x provides extended disk I/O statistics per device, including %util and await, which directly indicate disk performance and bottlenecks. vmstat gives a high-level view but lacks per-device detail, top focuses on CPU and memory, and netstat is for network interfaces. Therefore, iostat is the correct tool for diagnosing disk I/O issues.

Answer

vmstat 2

Answer

top

Answer

netstat -i

Question 9

A server administrator is troubleshooting a physical server that emits a continuous amber health LED and whose operating system logs show correctable memory errors increasing on one DIMM slot. The server is still running production workloads. Which of the following actions should the administrator take? (Choose two.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The network interface card (NIC) is configured for half duplex due to autonegotiation failure.. A duplex mismatch between the NIC and switch causes collisions and dropped packets, leading to intermittent connectivity issues. The switch port is set to full duplex, so if the NIC is at half duplex, performance suffers. The correct answer identifies this mismatch.

Answer

The switch port is configured for jumbo frames, but the server NIC is not.

Answer

The Ethernet cable is faulty and needs to be replaced.

Answer

The NIC driver is outdated and needs to be updated.

Question 10

A server administrator is replacing a failed hard drive in a RAID 5 array on a production server. The server supports hot-swap drives. Which of the following should the administrator do FIRST to replace the drive?

Accepted Answer

Remove the failed drive and insert the replacement drive.. With hot-swap support, the failed drive can be removed and replaced while the server remains online. The RAID controller will detect the new drive and begin rebuilding the array. Powering down, reconfiguring RAID, or performing a full backup first are unnecessary and would introduce downtime or delay. The correct first action is to physically replace the drive.

Answer

Reconfigure the RAID array to RAID 6 before replacing the drive.

Answer

Power down the server before replacing the drive.

Answer

Back up all data on the server before replacing the drive.

Question 11

A technician is preparing to install a new 2U rack server into a cabinet that already hosts several running servers. The technician must ensure proper airflow and physical security. Which of the following actions should the technician take? (Choose two.)

Accepted Answer

Secure the server to the rails and cabinet using the front thumbscrews or captive fasteners. Rack servers must face the cold aisle so intake air stays cool, and they must be fastened to the rails to prevent movement that could disturb adjacent cabling. These two actions address airflow integrity and physical security respectively. Reversing orientation breaks thermal containment, while removing the bezel or mischaracterizing blanking panels does not satisfy the stated requirements.

Answer

Install the server so its rear exhaust faces the cold aisle to shorten the cable runs

Answer

Fill every empty rack unit with a blanking panel to increase overall airflow volume

Answer

Leave the front bezel off to maximize unrestricted intake airflow

Question 12

A hospital's server room has a raised floor and a dedicated UPS circuit. During a scheduled power maintenance window, the facilities team must cut utility power to replace a breaker panel. The UPS must keep the two domain controllers and the electronic medical records (EMR) database server running for at least 20 minutes so they can be gracefully shut down. Which configuration should the administrator verify FIRST to meet this requirement?

Accepted Answer

The UPS battery runtime at the current load and the load percentage relative to UPS capacity. The deciding factor for surviving a planned utility cut is whether the UPS can supply the connected load for the required duration. Runtime depends on battery capacity and the actual load drawn by the domain controllers and EMR database server. Confirming runtime at current load is the only option that directly validates the 20-minute requirement before the maintenance window begins.

Answer

The UPS network management card's SNMP community string and trap destination

Answer

The redundant power supply configuration of the servers connected to the UPS

Answer

The automatic voltage regulation (AVR) settings on the UPS

Question 13

A technician is installing a new server with a hardware RAID controller. The server will host a database that requires high write performance and redundancy. The technician configures four SSDs in a RAID 10 array. After installation, the operating system reports the array as 1.2TB, but the technician expected 2.4TB. Which of the following explains the discrepancy?

Accepted Answer

RAID 10 uses mirroring and striping, so only half of the raw capacity is available for data.. RAID 10 requires a minimum of four drives and provides both striping and mirroring. The usable capacity is always 50% of the total raw capacity because each block is written to two drives. In this scenario, four 600GB drives yield 2.4TB raw and 1.2TB usable. The technician's expectation of 2.4TB would only be correct for RAID 0 or a non-redundant configuration.

Answer

The operating system is using a 512-byte sector size instead of 4K, reducing usable capacity.

Answer

The RAID controller is configured for RAID 5, which uses one drive for parity.

Answer

The SSDs are not compatible with the RAID controller, causing a size mismatch.

Question 14

A server administrator is installing a new 2U rack server into a datacenter rack. The server has two hot-swap 1100W power supplies. The rack currently has a 30A/208V single-phase PDU that is only 40% loaded. The administrator connects both power supplies to the same PDU. After a few months, one power supply fails, but the server remains operational. Which of the following should the administrator do to improve power redundancy?

Accepted Answer

Connect one power supply to a different PDU on a separate power feed.. The server currently has both power supplies connected to the same PDU, creating a single point of failure. To achieve true power redundancy, each power supply must be connected to a separate power source, ideally on different circuits or feeds. This ensures that if one PDU or feed fails, the server continues to operate on the remaining supply.

Answer

Install a redundant PDU in the same rack and connect both power supplies to it.

Answer

Enable power capping on the server to reduce the load on the PDU.

Answer

Replace the 1100W power supplies with higher-wattage units.

Question 15

A technician is installing a new 2U rack server in a data center. The server documentation specifies that the rail kit must be mounted in a rack with square-hole mounting holes, but the existing rack cabinet uses round threaded holes. The technician needs the server to slide in and out of the rack for maintenance while remaining securely supported. Which of the following should the technician do?

Accepted Answer

Obtain a rail kit or adapter designed for round threaded-hole racks and install the server with it. Round threaded-hole racks and square-hole racks use different mounting hardware and hole geometry, so a rail kit built for square holes will not seat correctly in a threaded-hole rack. The proper resolution is to use a rail kit or adapter bracket specifically designed for round threaded-hole racks, which maintains the sliding function and rated load capacity the technician needs for routine maintenance access.

Answer

Drill new square holes in the rack posts so the supplied rails fit

Answer

Install the rails using the included cage nuts and screws in the round holes

Answer

Place the server on fixed shelf rails and skip the sliding rail installation
