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 /

If the server 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, then the most likely reason for the lack of connectivity is that the VLAN is improperly configured. A VLAN (Virtual Local Area Network) is a logical grouping of network devices that share the same broadcast domain and can communicate with each other without routing. If the server is assigned to a different VLAN than the DHCP server or the default gateway, itwill not be able to obtain an IP address or reach other network devices. The DNS configuration is not relevant for network connectivity, as DNS only resolves names to IP addresses. The OS version is not likely to be incompatible with the network switch vendor, as most network switches use standard protocols and interfaces. The HIDS (Host-based Intrusion Detection System) is not likely to prevent the connection, as HIDS only monitors and alerts on suspicious activities on the host.

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 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.
