Secure Sockets Layer (SSL): SSL and its successor Transport Layer Security (TLS) enable client and server computers to establish a secure connection session and manage encryption and decryption activities.

The RAID level that provides the highest possible capacity for a storage array is RAID 0. RAID 0 is a type of RAID level that provides performance enhancement by using striping. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. RAID 0 does not provide any fault tolerance or redundancy, as it does not use any parity or mirroring techniques. RAID 0 uses all of the available disk space for data storage, without losing any space for overhead. Therefore, RAID 0 provides the highest possible capacity for a storage array, but also has the highest risk of data loss.

The first thing that the technician should ensure to correct the database synchronization errors is that NTP is running on the database system. NTP (Network Time Protocol) is a protocol that synchronizes the clocks of network devices with a reference time source, such as an atomic clock or a GPS receiver. NTP ensures that all devices on a network have accurate and consistent time settings, which can affect various functions and applications. Database synchronization is a process of maintaining data consistency and integrity across multiple database servers or instances. Database synchronization can depend on accurate time settings, as time stamps are often used to determine which data is newer or older, and which data should be updated or overwritten. If NTP is not running on the database system, it may cause time drift or discrepancy between different database servers or instances, which can result in synchronization errors or data conflicts.

The administrator should use the command mount –o remount,rw /newdisk to successfully mount the drive with the required parameters. The mount command is used to mount file systems on Linux systems. The –o option specifies options for mounting file systems. The remount option re-mounts an already mounted file system with different options. The rw option mounts a file system with read-write permissions. In this case, /newdisk is a mount point for a new hard disk that was mounted with read-only permissions by default. To allow users to create directories or files on /newdisk, the administrator needs to re-mount /
