SK0-005 Practice Test 6 — 10 Questions

Question 1

A server administrator notices that a recently installed PCIe network card is not being recognized by the operating system. The server is running Windows Server 2019. The administrator has verified that the card is securely seated and that the slot is enabled in the BIOS. Which of the following should the administrator try FIRST to resolve the issue?

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

Accepted Answer

Check the Hardware Compatibility List (HCL) for Windows Server 2019.. The first step when a newly installed device is not recognized should be to verify hardware compatibility with the operating system (checking the Hardware Compatibility List). This ensures the device has supported drivers. Options A and C are physical steps that have already been considered (secure seating, slot enabled), and D (updating BIOS) is a later step after confirming compatibility.

Answer

Replace the network card with a known-good card.

Answer

Reseat the network card in a different PCIe slot.

Answer

Update the server BIOS to the latest version.

Question 2

A server administrator is troubleshooting a Windows Server host that has been randomly losing connectivity to its iSCSI storage for the past week. The host has two dedicated NICs for iSCSI, each connected to a separate switch, and multipath I/O is configured. Event logs show intermittent path failures that recover within seconds. Switch port statistics show no errors, and both storage controllers report healthy. Which of the following should the administrator check FIRST to diagnose the intermittent path loss?

Accepted Answer

Review the host's TCP retransmission and timeout settings, and check for network congestion on the storage VLAN. Intermittent iSCSI path failures that recover within seconds, with clean switch port statistics and healthy storage controllers, point to packet loss or congestion on the storage network rather than a hardware fault. Reviewing TCP retransmission counters and timeout settings on the dedicated storage VLAN reveals whether frames are being dropped or delayed, which would cause the initiator to declare a path failed and then recover.

Answer

Replace the transceivers in both iSCSI NICs because intermittent link drops indicate failing optics

Answer

Confirm that the two iSCSI NICs are not participating in a team or spanning tree topology that introduces loops

Answer

Verify that the iSCSI initiator and target are configured with matching CHAP authentication secrets

Question 3

Refer to the exhibit. A Windows file server at a branch office lost network connectivity after a scheduled reboot. The administrator logs in via the console and runs `ipconfig /all`, which shows the output in the exhibit. The server should have a static IP of 10.0.0.50. What should the administrator do to restore connectivity?

Accepted Answer

Set a static IP configuration as intended.. The exhibit shows that the server's network adapter is configured to obtain an IP address automatically (DHCP), as indicated by 'DHCP Enabled: Yes' and an APIPA address of 169.254.x.x. Since the server should have a static IP of 10.0.0.50, the administrator must manually configure the static IP address, subnet mask, default gateway, and DNS servers. This will restore connectivity because the server will no longer rely on an unreachable DHCP server and will have the correct network configuration.

Answer

Disable IPv6 on the network adapter.

Answer

The DHCP server is unreachable; check DHCP server availability.

Answer

Release and renew the DHCP lease.

Question 4

A server administrator is upgrading the RAM on a server that supports quad-channel memory architecture. They install four identical 16GB DDR4 ECC modules, but the server only recognizes the memory as operating in single-channel mode. Which of the following is the most likely cause?

Accepted Answer

The DIMMs are not installed in the correct slots. Quad-channel memory requires the DIMMs to be installed in specific slots that are mapped to different memory channels. If the modules are placed in slots belonging to the same channel (e.g., all in channel A), the system will operate in single-channel mode. The correct slot population order is typically printed on the motherboard or in the server manual, often using color-coded slots to indicate channel grouping. Therefore, incorrect slot placement is the most likely cause of the single-channel operation.

Answer

One of the DIMMs is faulty

Answer

The DIMMs do not support ECC

Answer

The DIMMs are not registered (RDIMM)

Question 5

A server administrator needs to remotely manage a Windows Server 2022 Core installation that is located in a secure data center. The administrator's workstation runs Windows 11 and is on the same corporate network. Which of the following tools should the administrator use to manage the server with the GUI-based tools available?

Accepted Answer

Windows Admin Center. Windows Admin Center is a web-based GUI tool that can manage Windows Server Core installations remotely without requiring a GUI on the server. It is accessible from a Windows 11 workstation and provides a graphical interface for many administrative tasks. RDP to Core only offers a command line, Server Manager is not available on Windows 11, and PowerShell remoting is command-line only.

Answer

Remote Desktop Connection (RDP)

Answer

Server Manager installed locally on the workstation

Answer

PowerShell remoting using Enter-PSSession

Question 6

A server administrator is troubleshooting a Windows Server that is experiencing intermittent network disconnections. The server has a single NIC connected to a switch. Users report that access to file shares drops for about 30 seconds several times a day. The administrator reviews the switch logs and sees no port flapping. Which Windows tool should the administrator use to determine if the NIC is repeatedly resetting or if a driver is causing the disconnections?

Accepted Answer

Event Viewer, specifically the System log for network adapter events.. Intermittent network disconnections on a Windows server can be caused by NIC driver resets or hardware faults. The System event log in Event Viewer captures driver-level events, including link down/up, resets, and error codes. By filtering for the network adapter source, the administrator can see if the NIC is repeatedly resetting and correlate the timestamps with user reports. Other tools provide live metrics or configuration details but lack the historical event logging needed to diagnose intermittent hardware or driver behavior.

Answer

Performance Monitor with the Network Interface counter set.

Answer

Resource Monitor, Network tab.

Answer

Device Manager, viewing the NIC's properties and driver details.

Question 7

A technician is monitoring a server with a RAID 5 array that has a hot spare. One of the drives fails. Which of the following actions will occur automatically in this configuration?

Accepted Answer

The hot spare will be activated and the array will start rebuilding. In a RAID 5 array with a hot spare, when a drive fails, the controller automatically activates the hot spare and begins rebuilding the array using parity data from the remaining drives. This restores redundancy without manual intervention, keeping the array operational and protected.

Answer

The server will shut down to protect data

Answer

The array will continue to operate in degraded mode until manual intervention

Answer

The data will be mirrored to another server

Question 8

A Linux server administrator notices that the /var partition is 95% full. To free space quickly, the administrator decides to delete old log files. Which of the following commands should the administrator use to find and delete log files older than 30 days in the /var/log directory?

Accepted Answer

find /var/log -name "*.log" -mtime +30 -exec rm {} \;. The `find` command with `-mtime +30` locates files modified more than 30 days ago, and `-exec rm {} \;` safely deletes each file. Option B is syntactically invalid. Option C incorrectly pipes `ls` output through `grep` and then to `rm`, which does not accept piped input. Option D searches file contents for the text '30 days' rather than file age.

Answer

rm /var/log/*.log -30

Answer

ls -l /var/log/*.log | grep "30" | rm

Answer

grep -R "30 days" /var/log | xargs rm

Question 9

A server administrator notices that a database server is experiencing high CPU usage at specific times of the day. After checking logs, the administrator finds that a report generation task scheduled at those times is causing the issue. The task cannot be rescheduled or optimized further. Which of the following actions should the administrator take to ensure the server remains responsive for other applications during peak usage?

Accepted Answer

Configure the task to run at a lower priority.. Configuring the report generation task to run at a lower priority ensures that the operating system scheduler gives the database and other applications preferential access to CPU resources during peak times. This keeps the server responsive without changing hardware or rescheduling the task. Lowering priority is a non-disruptive, immediate mitigation that addresses the contention directly.

Answer

Add more virtual CPUs to the server's VM.

Answer

Move the database to a server with faster CPU cores.

Answer

Configure processor affinity to dedicate a core to the database process.

Question 10

A server administrator is troubleshooting a production server that boots successfully but intermittently reboots without warning. The IPMI event log shows no thermal or power events, and the OS logs show nothing before each reset. The administrator suspects a hardware fault and wants to capture the most detailed low-level diagnostic information the next time the server hangs or resets. Which of the following should the administrator configure to BEST collect this data?

Accepted Answer

Enable the platform's crash dump or NMI-on-hang feature so hardware state is saved on the next fault. When a server resets with no SEL, thermal, power, or OS log evidence, the fault is likely below the OS, so capturing platform-level state at the moment of failure is the only way to obtain actionable data. A hardware crash dump or NMI-triggered dump preserves CPU, memory, and firmware context that would otherwise be lost on reboot, making it the correct configuration for this scenario.

Answer

Enable the baseboard management controller's System Event Log (SEL) with a higher severity threshold

Answer

Enable the BMC's integrated management log and configure chassis intrusion detection alerts

Answer

Configure a memory dump of the operating system kernel to be written to a dedicated dump partition
