A hospital is migrating its electronic health record (EHR) system to a new Exadata X9M machine. Compliance regulations require that the database files, which are stored in ASM, must be encrypted. The security team also requires that the underlying operating system files on the database servers are protected by a FIPS 140-2 validated cryptographic module. Which Exadata security feature directly addresses the FIPS compliance requirement for the OS filesystem?
True or False: When adding a new database server to an existing physical Exadata Database Machine using the Oracle Exadata Deployment Assistant (OEDA), the process is fully automated and does not require any manual intervention after the initial configuration file is created.
An administrator is troubleshooting a client connectivity issue where applications are intermittently failing to connect to a database on an Exadata X9M machine. The administrator suspects a network configuration problem on the database server. Which utility provides the most comprehensive details about the state and configuration of the InfiniBand ports on the database server?
A new Exadata X9M implementation requires the creation of a general-purpose filesystem on the database servers for storing staging files and application binaries. The solution must leverage the existing ASM storage infrastructure for high availability and ease of management. Which Exadata feature should be used to create this filesystem?
A consultant is using the Oracle Exadata Deployment Assistant (OEDA) to plan a virtualized deployment. The customer has a requirement to create three separate VM clusters with different CPU and memory allocations for production, development, and testing environments. What is the correct procedure within the OEDA workflow to define these distinct VM clusters?
After a power outage in the data center, an Exadata X9M machine is being powered back on. To prevent component damage and ensure a clean startup, what is the correct sequence for powering on the machine components?
A security audit of an Exadata X9M machine has identified a vulnerability. To mitigate the risk, the administrator needs to prevent a specific database server, `db01`, from communicating with a specific storage server, `cell03`, over the RDMA network fabric. All other communication paths must remain active. Which command, run on `cell03`, will achieve this?
A database administrator needs to check the current temperature of the database servers in an Exadata Full Rack to ensure they are within the optimal operating range. The administrator wants to use the command-line interface on one of the database servers. Which `dbmcli` command will display the current temperature metric?
A storage administrator is tasked with replacing a failed hard disk in an Exadata X9M Storage Server. After replacing the physical drive, the new disk is not automatically added back to the ASM disk group. The administrator verifies the disk is physically sound and recognized by the cell. What is the most likely cause of this issue?
