質問 # 238
An administrator has been asked to deploy a database server that provides the highest performance with fault tolerance. Which of the following RAID levels will fulfill this request?
- A. RAID1
- B. RAID 10
- C. RAIDO
- D. RAID 6
- E. RAID 5
正解：B
解説：
Explanation
RAID 10 is the best option to deploy a database server that provides the highest performance with fault tolerance. RAID 10 is a type of RAID level that combines RAID 1 (mirroring) and RAID 0 (striping) to create an array of mirrored stripes. RAID 10 offers high performance by distributing data across multiple disks in parallel (striping), which improves read/write speed and I/O operations. RAID 10 also offers fault tolerance by duplicating data across two or more disks in each stripe (mirroring), which provides redundancy and data protection in case of disk failure. RAID 10 requires at least four disks to implement and has a high storage overhead, as half of the disk space is used for mirroring. References: [CompTIA Server+ Certification Exam Objectives]

- A. Rail kits
- B. A power distribution unit
- C. A wireless connection
- D. Cable management
正解：D
解説：
Explanation
The server administrator should use cable management to prevent network connectivity loss when pulling a server from the rack during maintenance. Cable management is a practice of organizing and securing the cables that connect various devices and components in a system. Cable management can help improve airflow, reduce clutter, prevent tangling, and avoid accidental disconnection or damage of cables. Cable management can be done using various tools and techniques, such as cable ties, cable trays, cable labels, cable organizers, or cable ducts.

質問 # 241
Ann, an administrator, is configuring a two-node cluster that will be deployed. To check the cluster's functionality, she shuts down the active node. Cluster behavior is as expected, and the passive node is now active. Ann powers on the server again and wants to return to the original configuration. Which of the following cluster features will allow Ann to complete this task?
- A. Heartbeat
- B. Load balancing
- C. Redundancy
- D. Failback
正解：D
解説：
Explanation
The cluster feature that will allow Ann to complete her task is failback. A cluster is a group of servers that work together to provide high availability, scalability, and load balancing for applications or services. A cluster can have different nodes or members that have different roles or states. An active node is a node that is currently running an application or service and serving requests from clients. A passive node is a node that is on standby and ready to take over if the active node fails. A failover is a process of switching from a failed or unavailable node to another node in a cluster. A failback is a process of switching back from a failover node to the original node after it becomes available again. Failback can be automatic or manual depending on the cluster configuration.
質問 # 242
A server administrator needs to keep a copy of an important fileshare that can be used to restore the share as quickly as possible. Which of the following is the BEST solution?
- A. Create an additional partition and move a copy of the fileshare
- B. Copy the fileshare to an LTO-4 tape drive
- C. Create a snapshot of the fileshare
- D. Configure a new incremental backup job for the fileshare
正解：C
解説：
The best solution to keep a copy of an important fileshare that can be used to restore the share as quickly as possible is to create a snapshot of the fileshare. A snapshot is a point-in-time copy of a file system or a volume that captures the state and data of the fileshare at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the fileshare after the snapshot was taken. A snapshot can be used to restore the fileshare to its previous state in case of data loss or corruption.
質問 # 243
A server administrator is completing an OS installation for a new server. The administrator patches the server with the latest vendor-suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity. Which of the following is the MOST likely reason for the lack of connectivity?
- A. The OS version is not compatible with the network switch vendor.
- B. The DNS configuration Is invalid.
- C. The HIDS is preventing the connection.
- D. The VLAN Is improperly configured.
正解：D
解説：
An intermediate distribution frame (IDF) is a free-standing or wall-mounted rack for managing and interconnecting a telecommunications cable between end-user devices and the main distribution frame (MDF).
DNS has nothing to do with LAN network connectivity. OS version and Switch vendor is not a thing. And the HIDS is detection not prevention. The only choice left is VLAN.

質問 # 245
Users ate experiencing issues when trying to access resources on multiple servers. The servers are virtual and run on an ESX server. A systems administrator is investigating but is unable to connect to any of the virtual servers. When the administrator connects to the host, a purple screen with while letters appears. Which of the following troubleshooting steps should the administrator perform FIRST?
- A. Reinstall the ESX server.
- B. Check the power supplies
- C. Review the log files.
- D. Reseat the processors.
正解：C
解説：
Explanation
A purple screen with white letters on an ESX server indicates a kernel panic, which is a fatal error that causes the system to crash and stop functioning . The first troubleshooting step that an administrator should perform is to review the log files, which may contain information about the cause of the error, such as hardware failures, software bugs, or configuration issues . Checking the power supplies (A) may not be relevant, as the system is still displaying a screen. Reinstalling the ESX server or reseating the processors (D) are drastic measures that may result in data loss or further damage, and should only be attempted after ruling out other possible causes.
