COMPLETE EXAM BANK WITH CORRECT
ANSWERS AND RATIONALES. A+ GRADED
1. A company is designing a globally distributed
application across two OCI regions (Frankfurt and
Ashburn). The application must maintain data
consistency with sub-second latency. Which OCI
database service is best suited?
A) Autonomous Data Guard across regions
(automated failover, but not low-latency consistent
reads across regions)
B) Oracle GoldenGate with bidirectional replication
(active-active)
C) MySQL Database Service with cross-region
replication (asynchronous)
D) Object Storage with cross-region replication
Correct answer: B
Rationale: GoldenGate supports active-active
bidirectional replication with conflict detection and
resolution, enabling multi-region write access with
low latency.
,2. A company needs to connect three VCNs in the
same region to each other (hub-and-spoke). Which
OCI component is most cost-effective and provides
centralized routing?
A) Local Peering Gateway (LPG) with transitive
routing (not supported — LPG is point-to-point)
B) Dynamic Routing Gateway (DRG) as a hub
(transitive routing)
C) VCN peering (direct LPG between each spoke —
full mesh)
D) Internet Gateway with VPN
Correct answer: B
Rationale: DRG supports transitive routing (hub-and-
spoke). Spoke VCNs attach to the DRG, which routes
traffic between them.
3. A company requires private, dedicated, high-
bandwidth (10 Gbps) connectivity between its on-
premises data center and OCI. The connection must
be low latency and bypass the public internet. Which
OCI service should be used?
A) FastConnect (Dedicated or Partner)
B) VPN Connect (IPsec over internet)
,C) Site-to-Site VPN
D) Remote Peering
Correct answer: A
Rationale: FastConnect provides private dedicated
physical connections with consistent latency.
Dedicated FastConnect is direct; Partner
FastConnect uses a service provider.
4. An architect is designing a disaster recovery
solution for an Oracle Database on OCI. The
Recovery Time Objective (RTO) is 15 minutes, and
Recovery Point Objective (RPO) is 5 minutes. Which
DR strategy is most appropriate?
A) Autonomous Data Guard (across availability
domains or regions) with automatic failover
B) Manual backup to Object Storage and restore
(RPO hours)
C) Snapshot of block volume (RPO minutes, RTO tens
of minutes)
D) GoldenGate replication (sub-second RPO, but
complexity)
Correct answer: A
Rationale: Autonomous Data Guard provides
synchronous replication (within region, AD-level) or
, near-synchronous cross-region, with automatic
failover meeting RTO/RPO.
5. A company has multiple VCNs in different regions.
They want to interconnect all VCNs and on-premises
networks through a central hub. Which OCI
component should be used?
A) Dynamic Routing Gateway (DRG) with cross-
region peering and virtual circuits
B) Internet Gateway (for each VCN)
C) Local Peering Gateway (LPG) (region only)
D) Transit Gateway (not an OCI service; DRG is the
transit hub)
Correct answer: A
Rationale: DRG supports attachments from multiple
VCNs, cross-region peering, and virtual circuits
(FastConnect/VPN) for a hub-and-spoke topology.
6. An architect is designing a multi-tier web
application with public load balancer, web servers in
public subnet, and database in private subnet. The
database must not have a public IP address. Which
OCI gateway allows the web tier to access the
database?
