Which two options correctly describe methods for accessing and managing the Exadata Infrastructure?

• A.Direct SSH access to the Exadata Infrastructure compute nodes is permitted for customers with root privileges.
• B.The dbcli utility, used for database administration on VM DB Systems, can also be used to manage the Exadata Infrastructure.
• C.Customers have direct access to the Exadata storage cells, allowing them to modify storage configurations.
• D.Management of the Exadata Infrastructure is primarily performed through the Oracle Cloud Infrastructure (OCI) console and APIs.
• E.Exadata Infrastructure management is solely managed by Oracle and is not directly accessible to customers.

When provisioning an Exadata Database Service, which two networking components are mandatory?

• A.A public subnet for the Exadata Infrastructure to allow external access for monitoring.
• B.A private subnet for the client network to ensure secure database access.
• C.A Service Gateway to allow access to Oracle Services without traversing the public internet.
• D.A NAT Gateway for each VM within the VM Cluster to allow outbound internet access for patching.
• E.A private subnet for database backups to Oracle Cloud Infrastructure Object Storage.

In comparing NoSQL databases with relational databases, what constitutes a fundamental difference in their approach to data relationships?

• A.Relational databases primarily rely on foreign keys to define relationships, while NoSQL databases often embed related data within a single document or use application-level links.
• B.Relational databases offer no mechanism for defining relationships between different data sets.
• C.NoSQL databases exclusively use foreign keys to establish relationships, similar to relational database models.
• D.NoSQL databases universally lack the ability to represent relationships between data elements.

What are the two primary dimensions typically governed by table rate limits in Oracle NoSQL Database Cloud Service?

• A.CPU utilization and memory consumption.
• B.Storage capacity and network bandwidth.
• C.Read throughput and write throughput.
• D.Number of indexes and query complexity.

Which statement BEST describes the primary architectural distinction between Exadata Database Service and a traditional Oracle Database deployed on virtual machines in the cloud?

• A.Exadata Database Service utilizes only virtualized compute nodes, while traditional deployments use bare metal.
• B.Exadata Database Service integrates specialized, high-performance storage servers and a high- bandwidth, low-latency RDMA over Converged Ethernet (RoCE) network, optimized for database workloads, which are not present in typical cloud VM deployments.
• C.Exadata Database Service uses a completely different SQL parsing engine compared to a traditional Oracle Database.
• D.Exadata Database Service exclusively supports Oracle RAC, while traditional cloud deployments can support both single-instance and RAC databases.
