Which workload type is NOT optimized for Oracle Autonomous Database on Shared Exadata
Infrastructure?
C
Explanation:
Oracle Autonomous Database on Shared Exadata Infrastructure is optimized for data warehousing
(Option A), mixed workloads (Option B), and transaction processing (Option D), leveraging Exadata’s
performance and automation. High-performance computing (HPC, Option C), typically involving
compute-intensive tasks like simulations, is not a primary focus—OCI offers separate HPC solutions.
Oracle’s documentation confirms these workload optimizations.
Reference: OCI Autonomous Database guide, Exadata workload optimization docs.
What does the term "multicloud" mean and how can it help organizations manage their IT
infrastructure?
B
Explanation:
“Multicloud” refers to using services from multiple cloud providers (e.g., OCI, Azure, GCP) to
leverage their unique strengths, enhancing flexibility, resilience, and cost-efficiency. Option A
describes hybrid cloud, Option C is single-provider redundancy, and Option D is multi-region
deployment—not multicloud. Oracle’s multicloud strategy documentation defines this approach as a
key IT management enabler.
Reference: OCI Multicloud Architect overview, Oracle multicloud strategy docs.
A company is deploying multiple applications in Google Cloud and wants to access a centralized
Oracle Exadata Database Service located in Oracle Database@Google Cloud. They want to ensure
that the applications in different VPCs can securely communicate with the database without any
direct peering between the application VPCs. Which network topology should the company use to
securely connect applications in different VPCs to the centralized Oracle Exadata Database Service?
A
Explanation:
A hub-and-spoke topology with a network virtual appliance (NVA) in GCP allows multiple application
VPCs (spokes) to securely connect to a centralized Exadata Database Service (hub) without direct
peering between VPCs. The NVA manages traffic and security. Direct Connect (Option B) isn’t a GCP
term here, mesh peering (Option C) requires inter-VPC connections, and flat topology (Option D) is
insecure. Oracle’s networking guide supports this topology for Database@Google Cloud.
Reference: Oracle Database@Google Cloud networking guide, GCP hub-and-spoke documentation.
What are the main types of purchase offers for Oracle Database@Google Cloud?
B
Explanation:
Oracle Database@Google Cloud offers Public and Private purchase options via the Google Cloud
Marketplace. Public offers are standardized and directly available, while Private offers involve
negotiated terms with Oracle Sales. Options A and C are not official terms, and Free Tier (Option D)
doesn’t apply to this enterprise service. Oracle’s purchasing documentation defines these two types.
Reference: Oracle Database@Google Cloud purchase guide, Google Cloud Marketplace docs.
To achieve high availability in a 2-node RAC DB System in Oracle Cloud Infrastructure, what would
you use to distribute your nodes to provide database instance fault isolation?
C
Explanation:
In a 2-node Real Application Clusters (RAC) DB System in OCI, Fault Domains (FDs) within a single
Availability Domain (AD) are used to distribute nodes, ensuring fault isolation at the hardware level
(e.g., separate racks/power). Availability Domains (Option A) provide broader isolation but are
overkill for a 2-node setup within one region. Local/Remote regions (Options B and D) are
geographic, not instance-specific. Oracle’s HA documentation recommends FDs for RAC.
Reference: OCI RAC documentation, Fault Domains guide.
Which operations are performed in the Azure portal to manage Oracle Database@Azure resources?
C
Explanation:
In Oracle Database@Azure, the Azure portal is used to scale up Exadata infrastructure (e.g., adding
compute) and run software updates, aligning with its infrastructure management role. Database-
specific tasks like scaling resources or backups (Option A) and DR configurations (Option D) occur at
the database level, often via OCI tools. Option B incorrectly ties OCI services to Azure monitoring.
Oracle’s management guide specifies these Azure portal functions.
Reference: Oracle Database@Azure management documentation, Azure portal integration guide.
Which feature is supported in all Oracle Database editions in Oracle Cloud Infrastructure?
B
Explanation:
The In-Memory Database feature, which accelerates analytics and mixed workloads, is supported
across all Oracle Database editions in OCI (e.g., Standard, Enterprise). RAC (Option A), Data Guard
(Option C), and Advanced Security (Option D) are edition-specific or require additional
licensing/configurations. Oracle’s database feature matrix confirms In-Memory’s universal
availability in OCI deployments.
Reference: OCI Oracle Database editions guide, In-Memory Database documentation.
While configuring Oracle Interconnect for Google Cloud, which specific Interconnect Type must users
select when creating a VLAN attachment on the Google Cloud Platform (GCP) console?
A
Explanation:
For Oracle Interconnect for Google Cloud, users must select the Partner Interconnect Connection
type when creating a VLAN attachment in the GCP console. This type integrates with OCI’s
FastConnect via a partner network, enabling private connectivity. “Cross-Cloud Interconnect” (Option
B) is not a GCP term, Dedicated Interconnect (Option C) is for direct GCP connections, and VPN
(Option D) is unrelated. Oracle’s setup guide specifies Partner Interconnect for this multicloud link.
Reference: Oracle Interconnect for Google Cloud setup guide, GCP Partner Interconnect
documentation.
What is a key benefit of using Oracle Autonomous Database on Shared Exadata Infrastructure?
A
Explanation:
A primary benefit of Oracle Autonomous Database on Shared Exadata Infrastructure is its ability to
automatically tune and patch the database, reducing manual administration and improving
performance and security. Option B is unrelated to the shared infrastructure model, Option C
exaggerates storage (it’s scalable, not unlimited), and Option D is a general infrastructure feature,
not specific to Autonomous Database. Oracle’s documentation highlights automation as a core
advantage.
Reference: OCI Autonomous Database documentation, Shared Exadata Infrastructure guide.
Which is a database service that CANNOT be provisioned in the Oracle Public Cloud?
C
Explanation:
The “Oracle Public Cloud” typically refers to OCI’s broadly accessible cloud services. Autonomous
Database on Shared (Option A) and Dedicated Infrastructure (Option B) are available in OCI.
However, Exadata Database Service on Dedicated Infrastructure (Option C) is not a standard offering
in the public OCI context—it’s tied to specific deployments like Database@Azure or on-premises
Exadata, not the public cloud. Option D is fictitious. Oracle’s documentation clarifies Exadata’s
dedicated nature outside standard public offerings.
Reference: OCI Database Services overview, Exadata Database Service documentation.
During provisioning in Oracle Database@Azure, delegated subnets are linked with OCI VCN inside
the OCI pods in Azure. When do you perform this step during provisioning?
D
Explanation:
In Oracle Database@Azure, delegated subnets from an Azure VNet are linked to the OCI VCN within
OCI pods during the provisioning of the Oracle Exadata VM Cluster. This step occurs in the Azure
portal when you specify subnet details, enabling the Exadata infrastructure to communicate with
Azure resources. Option A is incorrect as container databases are provisioned later in OCI, not Azure.
Option B misplaces this as a prerequisite during account linking, and Option C is too vague, as it
references the broader service rather than the specific VM Cluster step. Oracle’s provisioning guide
confirms this timing.
Reference: Oracle Database@Azure provisioning documentation, Azure VNet integration guide.
Which type of routing does Oracle FastConnect use to exchange routing information between on-
premises networks and Oracle Cloud Infrastructure?
B
Explanation:
Oracle FastConnect uses Border Gateway Protocol (BGP) to dynamically exchange routing
information between on-premises networks and OCI, ensuring optimal path selection. OSPF (Option
A) and RIP (Option C) are not used, and static routing (Option D) is an option but not the default or
dynamic method. Oracle’s FastConnect documentation confirms BGP as standard. The original
question’s placeholder has been replaced with BGP as the correct answer.
Reference: OCI FastConnect networking guide, Oracle BGP configuration docs.
What is the primary function of the connectivity link between the OCI child site and the OCI parent
site in the context of Oracle Database@Google Cloud?
B
Explanation:
The connectivity link between the OCI child site (in GCP) and parent site (OCI) supports control plane
operations (e.g., infrastructure management) and data plane operations (e.g., backups, DR) via the
dark fiber network. Options A, C, and D are unrelated to this technical function. Oracle’s multicloud
architecture docs specify this dual-purpose link.
Reference: Oracle Database@Google Cloud architecture guide, OCI-GCP connectivity docs.
What is the primary difference between using Oracle FastConnect with an Oracle partner and using
FastConnect with colocation with Oracle?
D
Explanation:
FastConnect with an Oracle partner uses a third-party network to connect to OCI, while colocation
with Oracle involves a direct physical connection at an OCI data center. The difference lies in the
physical connection method, not locations (Option A), redundancy (Option B), or circuits (Option C).
Oracle’s FastConnect documentation outlines these deployment models.
Reference: OCI FastConnect overview, Oracle Networking guide.
How are the resources provisioned in Oracle Database@Azure service?
A
Explanation:
In Oracle Database@Azure, Oracle Exadata Infrastructure and Exadata VM Clusters are provisioned
via the Azure portal, integrating OCI database services into Azure’s ecosystem. Option B overextends
to include container/pluggable databases (managed separately), while Options C and D incorrectly
involve the OCI console—provisioning is Azure-native. Oracle’s documentation corrects the original
answer (C) to A.
