Server Hardware Installation and Management · Given a scenario, deploy and manage storage.
A financial services company is deploying a new high-frequency trading application on a bare-metal server. The application's performance is extremely sensitive to I/O latency. The server has been equipped with eight U.2 NVMe SSDs. To achieve the absolute lowest latency and highest possible IOPS for the application's scratch database, which RAID configuration should the administrator implement for these eight drives?
Show answer & explanation
Correct answer: B
For a high-frequency trading application where the primary concern is the absolute lowest latency and highest IOPS, and data is transient (scratch database), data redundancy is not a requirement. RAID 0 (striping) offers the best performance by striping data across all eight NVMe drives without the overhead of parity calculations (RAID 5/6) or mirroring (RAID 1/10). This configuration aggregates the performance of all drives, providing the maximum possible IOPS and lowest latency, which is critical for this specific use case.

Troubleshooting · Given a scenario, troubleshoot common hardware failures.
A server administrator is investigating an unplanned server shutdown. The out-of-band management logs show a critical temperature threshold was breached on the VRM (Voltage Regulator Module) immediately before the shutdown. All CPU and chassis fans are reporting normal RPMs. Which of the following is the MOST likely root cause of the VRM overheating?
Show answer & explanation
Correct answer: C
Server chassis are designed with precise airflow channels, often managed by plastic air baffles or shrouds. These components direct air from the fans over critical components like the CPU heatsinks and VRMs. If a baffle is missing or improperly seated after maintenance, airflow will not be correctly channeled. Even with fans at full speed, the VRM can overheat due to a lack of directed cooling, leading to a thermal shutdown. Since the CPU and chassis fans are working, a disruption in the engineered airflow path is the most probable cause.

Security and Disaster Recovery · Explain the importance of backups and restores.
A company's disaster recovery plan requires a full, bare-metal restore capability for its critical Linux servers. The backup strategy must ensure that all data, including the Master Boot Record (MBR), partition tables, and all file systems, can be recovered to new hardware. Which backup method should be implemented to meet this requirement?
Show answer & explanation
Correct answer: C
A bare-metal restore requires a complete, block-for-block copy of the entire storage device. The
ddcommand in Linux is a powerful utility for creating an exact image of a disk, including the MBR/GPT, partition tables, bootloaders, and all data within the file systems. This image can then be written to a new, identical or larger disk to perform a complete bare-metal recovery. File-level backups likersyncor LVM snapshots do not typically include the boot records and partition information necessary for this type of restore. - Question 9IntermediateSelect 2
Security and Disaster Recovery · Explain important concepts pertaining to identity and access management for server administration.
During a security audit, it was discovered that a junior administrator configured a service account for a new application with interactive logon rights and membership in the 'Domain Admins' group. This configuration violates which TWO of the following security principles? (Select TWO).
Show answer & explanation
Correct answers: B, D
The principle of least privilege is violated because the service account has 'Domain Admins' rights, which are far more than what is required for a typical application. Service accounts should only have the minimum permissions necessary to function.
Attack surface reduction is violated by granting interactive logon rights. Service accounts should be denied the ability to log on locally or via Remote Desktop to prevent them from being used as an entry point for an attacker. Their rights should be limited to 'Log on as a service'.

Troubleshooting · Given a scenario, troubleshoot network connectivity issues.
A system administrator is analyzing a server that is experiencing intermittent network dropouts. The server has a quad-port 10GbE NIC configured in an LACP team. The administrator runs
ethtoolon one of the member interfaces and sees a large number of 'RX packets with CRC error'. What is the MOST likely cause of this issue?Show answer & explanation
Correct answer: C
CRC (Cyclic Redundancy Check) errors are Layer 1 or Layer 2 issues, indicating that frames are being corrupted in transit. This is almost always caused by a physical problem, such as a bad or damaged cable, a failing SFP+ transceiver, a faulty switch port, or a bad NIC port. Since the errors are on the receive (RX) side, the problem lies in the path to the server. An IP conflict or LACP configuration issue would manifest as a Layer 3 or higher problem, not as physical frame corruption.
