A financial services company is deploying a new Exadata X9M Quarter Rack for a critical OLTP application. The security architect mandates that all administrative access to the storage servers must be strictly controlled and logged, and network traffic between database servers and storage servers must be isolated. During the OEDA configuration, which security feature should be configured to create firewall-like rules that restrict access to storage server services based on source IP addresses?

During a routine maintenance window, an administrator needs to update the firmware on a single, specific Exadata Storage Server without impacting the entire rack or causing application downtime. The update must be performed using the recommended command-line utility. Which command correctly initiates this process?

An Exadata administrator observes a sudden degradation in I/O performance for a specific database. Investigation reveals that a single flash card on one storage cell has failed. The administrator needs to replace the card. Which TWO statements accurately describe the process and its impact? (Select TWO)

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?
