LVM (Logical Volume Manager) is a tool that allows the technician to increase a partition’s size in the future without reformatting it on a Linux server. LVM creates logical volumes that can span across multiple physical disks or partitions and can be resized dynamically without losing data. LVM also provides other features such as snapshots, encryption, and RAID. DiskPart, fdisk, and Format are tools that can be used to partition and format disks, but they do not allow increasing a partition’s size without reformatting it.

The connection type that the server administrator is using to access the server remotely is out-of-band management. Out-of-band management is a method of accessing and controlling a server through a dedicated network interface or port that is separate from the regular data network. Out-of-band management allows administrators to perform tasks such as rebooting, configuring, troubleshooting, or updating a server even if the server is offline or unresponsive through the regular network. Out-of-band management can use protocols such as IPMI, iLO, DRAC, or BMC.Reference:https://www.ibm.com/cloud/learn/out-of-band-management

If a server has two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight-drive RAID 10 set for data, then the most likely failure scenario that caused the server to crash and not boot is that a drive failed in the OS array. RAID 0 is a RAID configuration that stripes data across two or more drives without parity or redundancy. RAID 0 offers high performance but no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 10 is a RAID configuration that combines disk mirroring and disk striping with parity. RAID 10 offers high performance and fault tolerance. RAID 10 can tolerate up to one drive failure per mirrored pair without losing data or functionality.References:https://www.technewstoday.com/what-is-a-raid-0/ https://www.technewstoday.com/what-is-a-raid-10/

The ping command output shows that the NIC has an IP address of 192.168.1.100 and a default gateway of 192.168.1.1. However, when the technician tries to ping the default gateway, the reply comes from another IP address: 192.168.1.101. This means that there is another device on the network that has the same IP address as the default gateway, and it is responding to the ping request instead of the intended destination.

A duplicate IP address can cause network connectivity problems, such as packet loss, routing errors, or unreachable hosts. To resolve this issue, the technician should either change the IP address of the default gateway or the device that is conflicting with it, or use DHCP to assign IP addresses automatically and avoid conflicts.

The other options are not correct because they do not explain the ping output. An incorrect default gateway would cause no reply or a destination unreachable message, not a reply from a different IP address. A DHCP misconfiguration would cause an invalid or no IP address on the NIC, not a duplicate IP address on the network. An incorrect routing table would cause routing errors or unreachable destinations, not a reply from a different IP address.
