A server administrator is configuring a new server that will hold large amounts of information. The server will need to be accessed by multiple users at the same time. Which of the following server roles will the administrator MOST likely need to install?
Correct Answer:
D
Few people are expected to use the database at the same time and users don’t need to customize the design of the database.

The server role that the administrator will most likely need to install for a server that will hold large amounts of information and will need to be accessed by multiple users at the same time is database. A database is a collection of structured data that can be stored, queried, manipulated, and analyzed using various methods and tools. A database server is a server that hosts one or more databases and provides access to them over a network. A database server can handle large amounts of information and support concurrent requests from multiple users or applications.
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?
Correct Answer:
E
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 company needs to increase the security controls on its servers. Anadministrator is implementing MFA on all servers using cost effective techniques. Which of the following should the administrator use to satisfy the MFA requirement?
Correct Answer:
B
Push notifications are messages that are sent from an application or a service to a user’s device without requiring the user to open or request them. They can be used as a cost- effective technique for implementing MFA (Multi-Factor Authentication) on servers by sending verification codes or approval requests to the user’s smartphone or tablet when they try to log in to the server.

Which of the following techniques can be configured on a server for network redundancy?
Correct Answer:
D
Teaming is a technique that can be configured on a server for network redundancy. Teaming involves combining two or more network adapters into a single logical unit that acts as one network interface. This way, if one network adapter fails, another one can take over without disrupting network connectivity. Teaming can also improve network performance by load balancing traffic across multiple network adapters. Clustering is a technique that involves grouping two or more servers together to act as one system for high availability and fault tolerance. Virtualizing is a technique that involves creating multiple virtual machines on a single physical server to optimize resource utilization and flexibility. Cloning is a technique that involves creating an exact copy of a server’s configuration and data for backup or migration purposes.

A datacenter in a remote location lost power. The power has since been restored, but one ol the servers has not come back online. After some investigation, the server is found to still be powered off. Which of the following is the BEST method to power on the server
remotely?
Correct Answer:
B
Out-of-band console is a tool that can be used to command a remote shutdown of a physical Linux server. Out-of-band console is a method of accessing a server’s console through a dedicated management port or device that does not rely on the server’s operating system or network connection. Out-of-band console can be used to power cycle, reboot, update firmware, monitor performance, and perform other tasks remotely even if the server is unresponsive or offline. Crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be used to troubleshoot a server on-site, but it requires physical access to the server. IP KVM (Internet Protocol Keyboard Video Mouse) switch is a hardware device that allows remote access to multiple servers using a web browser or a client software, but it requires network connectivity and may not work if the SSH connection is lost. RDP (Remote Desktop Protocol) is a protocol that allows remote access to a Windows server’s graphical user interface, but it does not work on Linux servers and requires network connectivity.
