A technician needs to install a Type 1 hypervisor on a server. The server has SD card slots, a SAS controller, and a SATA controller, and it is attached to a NAS. On which of the following drive types should the technician install the hypervisor?
Correct Answer:
A
A SD card is a type of flash memory card that can be used to store data and run applications. A SD card can be used to install a Type 1 hypervisor on a server, as it provides fast boot time, low power consumption, and high reliability. A Type 1 hypervisor runs directly on the underlying computer’s physical hardware, interacting directly with its CPU, memory, and physical storage. For this reason, Type 1 hypervisors are also referred to as bare-metal hypervisors. A Type 1 hypervisor takes the place of a host operating system and VM resources are scheduled directly to the hardware by the hypervisor123. A NAS drive (B) is a type of network-attached storage (NAS) device that provides shared access to files and data over a network. A NAS drive cannot be used to install a Type 1 hypervisor on a server, as it requires a network connection and a host operating system to function. A SATA drive © is a type of hard disk drive (HDD) or solid state drive (SSD) that uses the Serial ATA (SATA) interface to connect to a computer. A SATA drive can be used to install a Type 1 hypervisor on a server, but it may have some disadvantages compared to a SD card, such as slower boot time, higher power consumption, and lower reliability. A SAS drive (D) is a type of hard disk drive (HDD) or solid state drive (SSD) that uses the Serial Attached SCSI (SAS) interface to connect to a computer. A SAS drive can also be used to install a Type 1 hypervisor on a server, but it may have similar disadvantages as a SATA drive, and it may also be more expensive and less compatible than a SD card.References: 1 https://phoenixnap.com/kb/what-is-hypervisor-type-1-22

A server technician is deploying a server with eight hard drives. The server specifications call for a RAID configuration that can handle up to two drive failures but also allow for the least amount of drive space lost to RAID overhead. Which of the following RAID levels should the technician configure for this drive array?
Correct Answer:
C
The technician should configure RAID 6 for this drive array to meet the server specifications. RAID 6 is a type of RAID level that provides fault tolerance and performance enhancement by using striping and dual parity. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. Parity means calculating and storing extra information that can be used to reconstruct data in case of disk failure. RAID 6 uses two sets of parity information foreach stripe, which are stored on different disks. This way, RAID 6 can handle up to two disk failures without losing any data or functionality. RAID 6 also allows for the least amount of drive space lost to RAID overhead compared to other RAID levels that can handle two disk failures, such as RAID 1+0 or RAID 0+1.

A technician is setting up a small office that consists of five Windows 10 computers. The technician has been asked to use a simple IP configuration without manually adding any IP addresses. Which of the following will the technician MOST likely use for the IP address assignment?
Correct Answer:
D
DHCP stands for Dynamic Host Configuration Protocol and it is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. DHCP can help simplify IP configuration without manually adding any IP addresses. DHCP works by using a DHCP server that maintains a pool of available IP addresses and leases them to devices that request them. The devices can renew or release their IP addresses as needed.References: https://www.comptia.org/training/resources/exam-objectives/comptia-server-sk0-005-exam- objectives (Objective 2.1)
A server is performing slowly, and users are reporting issues connecting to the application on that server. Upon investigation, the server administrator notices several unauthorized services running on that server that are successfully communicating to an external site. Which of the following are MOST likely causing the issue?
(Choose two.)
Correct Answer:
CF
The server is infected with a virus and SELinux is enabled on the server are most likely causing the issue of unauthorized services running on the server. A virus is a type of malicious software that infects a system and performs unwanted or harmful actions, such as creating, modifying, deleting, or executing files. A virus can also create backdoors or open ports on a system to allow remote access or communication with external sites. SELinux (Security-Enhanced Linux) is a security module for Linux systems that enforces mandatory access control policies on processes and files. SELinux can prevent unauthorized services from running on a server by restricting their access to resources based on their security context. However, SELinux can also cause problems if it is not configured properly or if it conflicts with other security tools.
Which of the following allows for a connection of devices to both sides inside of a blade enclosure?
Correct Answer:
A
The component that allows for a connection of devices to both sides inside of a blade enclosure is midplane. A midplane is a board or panel that connects two sets of connectors or devices in parallel with each other. A midplane is typically used in blade enclosures or chassis to provide power and data connections between blade servers on one side and power supplies, cooling fans, switches, or management modules on the other side. A midplane can also act as a backplane by providing bus signals or communication channels between devices.
