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

Accepted Answer

Configure NIC teaming for redundancy and load balancing.. Enabling jumbo frames and configuring NIC teaming are direct performance optimizations for a high-traffic web server. Jumbo frames reduce overhead for large transfers, while NIC teaming provides redundancy and load balancing. The other options either degrade performance or do not directly enhance it. These two together can significantly improve network throughput and reliability.

Answer

Assign a static IP address to the server.

Answer

Disable TCP offloading on the network adapter.

Answer

Set the network adapter to half-duplex mode.

Question 2

A server administrator needs to deploy a new server that will host a database requiring high random read/write performance and maximum fault tolerance. The server has eight drive bays. Which RAID level should the administrator choose?

Accepted Answer

RAID 10. RAID 10 is the best choice for database servers needing high random I/O performance and fault tolerance. It stripes data across mirrored pairs, delivering fast reads and writes while allowing for drive failures. RAID 0 lacks redundancy, RAID 5 has write penalties and only single-drive fault tolerance, and RAID 6 has even greater write overhead. RAID 10 balances performance and redundancy effectively.

Answer

RAID 6

Answer

RAID 0

Answer

RAID 5

Question 3

A company has a Windows Server 2022 server that runs a critical application. The server has a single power supply. The IT manager wants to ensure that the server can continue to operate during a brief power outage and can shut down gracefully during an extended outage. Which solution should the administrator implement?

Accepted Answer

Connect the server to an uninterruptible power supply (UPS) with a network management card. A UPS with a network management card provides both battery backup and the ability to initiate a graceful shutdown when the battery is depleted. This directly addresses the need to ride through short outages and to shut down safely during longer ones. Other options address hardware redundancy but not power outage protection.

Answer

Install a second power supply and connect it to a different power circuit

Answer

Install a redundant power supply

Answer

Configure the server to use a redundant array of independent disks (RAID) for the operating system drive

Question 4

A company has a server running Windows Server 2022 with two 10-Gbps network adapters. The server hosts a high-traffic web application that requires maximum throughput and fault tolerance. The network switches support 802.3ad link aggregation. The administrator configures NIC teaming using LACP with Address Hash. After deployment, users report intermittent connectivity issues. Which of the following is the MOST likely cause?

Accepted Answer

The switch ports are not configured for LACP.. The most likely cause is that the switch ports are not configured for LACP. LACP requires configuration on both the server and the switch to form a link aggregation group. Without proper switch configuration, the team will not function correctly, causing intermittent connectivity.

Answer

The load balancing mode should be Dynamic instead of Address Hash.

Answer

The server's network adapters are not identical models.

Answer

The NIC teaming mode should be Switch Independent instead of LACP.

Question 5

A server administrator is troubleshooting a Windows Server 2019 server that is experiencing slow performance. The administrator suspects that a specific process is consuming excessive CPU resources. Which of the following tools should the administrator use to identify the process?

Accepted Answer

Task Manager. Task Manager is the best tool for quickly identifying a process consuming excessive CPU. It provides a real-time list of processes with CPU usage percentages, allowing the administrator to sort and pinpoint the culprit. While other tools offer more detailed analysis, Task Manager is the most direct and efficient for this immediate troubleshooting need.

Answer

Performance Monitor

Answer

Event Viewer

Answer

Resource Monitor

Question 6

A server administrator is implementing a backup strategy for a Windows Server 2022 file server. The administrator needs to ensure that backups can be restored quickly and that the backup data is protected against ransomware. Which two actions should the administrator take? (Choose two.)

Accepted Answer

Use a cloud backup service that supports immutable backups and versioning.. To protect backups from ransomware and ensure quick restoration, the administrator should keep backups offline or use immutable cloud storage. An offline USB drive is inaccessible to ransomware when disconnected, and immutable cloud backups cannot be altered. Both approaches provide strong protection and enable reliable recovery.

Answer

Enable deduplication on the backup target to reduce storage consumption.

Answer

Store backups on a network share that is accessible using domain administrator credentials.

Answer

Schedule backups to run only during off‑peak hours to minimize performance impact.

Question 7

A system administrator is configuring a new server that will run a high-performance database. The server has four 1 TB NVMe drives and a hardware RAID controller that supports RAID 0, 1, 5, 6, 10, and 50. The database workload is write-intensive with random I/O. The administrator needs to maximize performance while providing redundancy against a single drive failure. Which RAID level should the administrator choose?

Accepted Answer

RAID 10. For a write-intensive random I/O database workload, RAID 10 is the best choice because it provides redundancy and superior write performance by avoiding parity overhead. RAID 0 lacks redundancy, while RAID 5 and RAID 6 incur write penalties that would hinder performance. RAID 10 meets both the performance and redundancy requirements.

Answer

RAID 6

Answer

RAID 5

Answer

RAID 0

Question 8

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 9

A company has a Windows Server 2022 server that runs a custom application which writes heavily to a local SSD. The administrator notices that the SSD's wear-leveling indicator shows significant wear after only six months. The server logs show frequent small write operations. Which action should the administrator take to reduce SSD wear while maintaining performance?

Accepted Answer

Configure the application to batch small writes into larger sequential writes.. The most effective way to reduce SSD wear from frequent small writes is to batch them into larger sequential writes, which lowers write amplification. This maintains performance while extending the drive's lifespan. Moving logs within the same SSD or enabling write caching does not reduce the total bytes written, and disabling the page file introduces instability without addressing the application's write pattern.

Answer

Move the application's log files to a different volume on the same SSD.

Answer

Enable write caching on the SSD controller.

Answer

Disable the page file on the SSD.

Question 10

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 11

A server administrator is configuring a new server that will host a high-traffic web application. The administrator needs to optimize the server's network performance. Which TWO of the following should be implemented? (Choose two.)

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

Accepted Answer

Highly available file server role in Failover Cluster Manager. The correct answer is to configure a highly available file server role in Failover Cluster Manager. This creates a clustered role that includes all necessary resources and enables automatic failover between cluster nodes. Other options like CSV, file share witness, or DFSR serve different purposes and do not directly provide automatic failover for a file server role.

Answer

Cluster Shared Volume (CSV)

Answer

File Server role with a file share witness

Answer

Distributed File System Replication (DFSR)

Question 12

A server administrator is troubleshooting a Linux server that is experiencing random reboots. The administrator checks the system logs and finds multiple entries indicating a machine check exception (MCE). The administrator suspects a hardware issue. Which of the following should the administrator do to further diagnose the problem? (Choose two.)

Accepted Answer

Check the CPU temperature and cooling system.. Machine check exceptions indicate hardware faults. The most likely components are RAM and CPU overheating. Running memtest86+ tests memory integrity, and checking CPU temperature and cooling ensures thermal issues are not causing the MCEs. These two steps directly address common hardware causes. Other options are either too drastic or not directly related to MCE diagnosis.

Answer

Reinstall the operating system.

Answer

Run a disk check with fsck.

Answer

Update the BIOS/UEFI firmware.

Question 13

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 14

A server administrator manages a Linux server running a custom application. The application must start automatically at boot and be restarted if it crashes. The administrator creates a systemd unit file at /etc/systemd/system/myapp.service. After running systemctl daemon-reload and systemctl start myapp, the application runs successfully. However, after a reboot, the application does not start. Which command should the administrator run to resolve this?

Accepted Answer

systemctl enable myapp. To make a systemd service start automatically at boot, the administrator must enable it using systemctl enable. This creates the necessary symbolic links in the systemd target directories. Starting, reloading, or reloading the daemon does not configure the service for automatic startup, so enabling is the correct action.

Answer

systemctl daemon-reload

Answer

systemctl start myapp

Answer

systemctl reload myapp

Question 15

A server administrator is configuring a new server that will host a high-traffic web application. The administrator needs to optimize the server's network performance. Which TWO of the following should be implemented? (Choose two.)

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

Accepted Answer

The ExecStart path points to a non-existent or non-executable file.. The 203/EXEC status code indicates that systemd failed to execute the command specified in ExecStart. This is typically due to an incorrect path, missing execute permission, or a missing interpreter. The administrator should check that the file exists, is executable, and has a proper shebang if it is a script. Other options do not produce this exact error.

Answer

SELinux is blocking the service from accessing its log file.

Answer

The service unit file has the wrong permissions.

Answer

The service is missing a [Install] section in the unit file.
