Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q34-Q39):

NEW QUESTION # 34
You are designing an OCI VCN for a new application with the following requirements: The application servers in a private subnet must be able to download software updates from public repositories on the internet; the application servers must NOT be directly accessible from the public internet; the application servers must also be able to access Oracle Cloud Infrastructure Registry (OCIR) within the same region to pull container images. Which combination of VCN Gateways BEST meets these requirements?

A. NAT Gateway and Internet Gateway
B. Dynamic Routing Gateway (DRG) and Internet Gateway
C. Internet Gateway and Service Gateway
D. NAT Gateway and Service Gateway

Answer: D

Explanation:
* Requirements: Outbound internet access, no inbound exposure, and private OCIR access.
* Option A: Internet Gateway allows inbound traffic, violating the no-exposure rule-incorrect.
* Option B: NAT Gateway enables outbound-only internet access, but Internet Gateway adds inbound exposure-incorrect.
* Option C: NAT Gateway provides outbound internet access without inbound exposure; Service Gateway enables private OCIR access-correct.
* Option D: DRG is for external networks, not internet/OCIR access; Internet Gateway exposes servers- incorrect.
* Conclusion: Option C satisfies all requirements.
Oracle states:
* "Use a NAT Gateway for outbound internet access from private subnets without inbound connectivity.
Use a Service Gateway for private access to OCI services like OCIR."This supports Option C.
Reference:NAT and Service Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas
/Content/Network/Tasks/NATgateway.htm & docs.oracle.com/en-us/iaas/Content/Network/Tasks
/servicegateway.htm).

NEW QUESTION # 35
Which OCI component facilitates transitive routing between VCNs in different regions via a dedicated, private network backbone, while also enabling connectivity to on-premises networks?

A. Service Gateway
B. Internet Gateway
C. Dynamic Routing Gateway (DRG)
D. Local Peering Gateway (LPG)

Answer: C

Explanation:
* Requirement:Transitive routing across regions and to on-premises, privately.
* Components:
* LPG:Intra-region VCN peering; limited scope.
* DRG:Cross-region and on-premises routing via private backbone.
* Service Gateway:OCI service access; not transitive.
* Internet Gateway:Public internet; not private.
* Evaluate Options:
* A:Region-specific; incorrect.
* B:Supports multi-region and on-premises; correct.
* C:Service-focused; incorrect.
* D:Public; incorrect.
* Conclusion:DRG is the key component.
DRG enables complex routing scenarios. The Oracle Networking Professional study guide notes, "The Dynamic Routing Gateway (DRG) facilitates transitive routing between VCNs in different regions and on- premises networks over OCI's private backbone" (OCI Networking Documentation, Section: Dynamic Routing Gateway). This meets both requirements efficiently.

NEW QUESTION # 36
You are working as an OCI Network Specialist. Your company is migrating its on-premises IPv6 network to OCI. As part of the migration, you need to enable communication between the on-premises network and a VCN in OCI using FastConnect. Your company utilizes global unicast IPv6 addresses on-premises and wants to continue utilizing those addresses in OCI. However, you have a restriction that compute instance traffic must be limited to IPv6 only. After assigning IPv6 addresses from the prefix to the instance, they cannot ping external IPv6 addresses. What configuration most likely addresses this issue?

A. Ensure that there are IPv6 default routes (::/0) pointing to a NAT Gateway in your VCN route tables.
B. Ensure that there is a Service Gateway attached to the VCN with a default route (::/0) in your subnet route table.
C. Ensure that there is an Internet Gateway (IGW) attached to the VCN with a default route (::/0) in your subnet route table.
D. You can't use your own IPv6 address space in OCI. You must use OCI's provided ULA.

Answer: C

Explanation:
* Problem: Instances with IPv6-only traffic can't ping external IPv6 addresses despite FastConnect and IPv6 prefixes.
* Option A: OCI supports Bring Your Own IP (BYOIP) for IPv6, including global unicast addresses, so this is incorrect.
* Option B: NAT Gateways are for IPv4 outbound traffic, not IPv6-irrelevant here.
* Option C: For IPv6-only instances to reach external IPv6 addresses (beyond FastConnect),an Internet Gateway (IGW) is required with a default route (::/0) in the subnet route table. This enables public IPv6 connectivity-correct.
* Option D: Service Gateway is for OCI services, not general IPv6 internet access-incorrect.
* Conclusion: Option C fixes the issue by enabling IPv6 internet access.
Oracle states:
* "To enable IPv6 traffic to the internet, attach an Internet Gateway to the VCN and add a route rule for ::
/0. OCI supports BYOIP for public IPv6 prefixes."This aligns with Option C. Reference:IPv6 in OCI - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingIPv6.htm).

NEW QUESTION # 37
You are designing a highly available web application on OCI. The application needs to be accessible globally with traffic being routed to the nearest region based on user location. Additionally, you need to implement sophisticated traffic management policies, such as A/B testing and weighted traffic distribution based on application version. You also require protection against DDoS attacks. Which OCI load balancing solution is best suited for these requirements?

A. Global Load Balancer with Traffic Management Steering Policies
B. Network Load Balancer
C. Flexible Load Balancer
D. Regional Load Balancer

Answer: A

Explanation:
* Requirements:Global access, geo-routing, advanced traffic management, DDoS protection.
* Load Balancer Options:
* Regional LB:Single-region, no global routing or advanced policies.
* NLB:Layer 4, no HTTP-based traffic management or DDoS features.
* Global LB with Steering Policies:Layer 7, supports geo-routing and policies.
* Flexible LB:Not a specific OCI service.
* Assess Fit:
* A:Lacks global and advanced features; unsuitable.
* B:No Layer 7 or DDoS protection; incorrect.
* C:Meets all requirements with geo-routing, steering policies, and WAF integration; best fit.
* D:Non-existent service; incorrect.
* Conclusion:Global LB with steering policies is the best solution.
The Global Load Balancer with Traffic Management Steering Policies supports global applications. The Oracle Networking Professional study guide explains, "Global Load Balancer enables geo-based routing and advanced traffic policies like A/B testing and weighted distribution, integrating with OCI WAF for DDoS protection" (OCI Networking Documentation, Section: Load Balancing - Traffic Management). This aligns with all specified requirements.

NEW QUESTION # 38
You are responsible for maintaining the network connectivity between OCI and Azure using the OCI-Azure Interconnect. You need to perform planned maintenance on your on-premises network, which will temporarily disrupt the BGP (Border Gateway Protocol) sessions between your on-premises network and both OCI and Azure. You want to ensure that traffic between OCI and Azure continues to flow without interruption during the maintenance window. Which action is MOST important to take before starting the maintenance to ensure continuous connectivity between OCI and Azure?

A. Configure static routes in OCI and Azure to directly route traffic between the VCNs/VNets without relying on BGP.
B. Disable the BGP sessions on both OCI and Azure before starting the maintenance.
C. Notify Oracle and Microsoft support teams about the planned maintenance window.
D. Increase the BGP keepalive timers on both OCI and Azure to prevent the sessions from timing out.

Answer: A

Explanation:
* Goal: Ensure OCI-Azure traffic during BGP disruption.
* Option A: Static routes bypass BGP dependency, maintaining connectivity-correct.
* Option B: Disabling BGP stops routing-incorrect.
* Option C: Notification doesn't ensure connectivity-incorrect.
* Option D: Keepalive timers delay detection, not prevent disruption-incorrect.
* Conclusion: Option A is most critical.
Oracle notes:
* "For uninterrupted OCI-Azure Interconnect traffic during BGP maintenance, configure static routes between VCNs and VNets."This supports Option A. Reference:OCI-Azure Interconnect - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/ociazureinterconnect.htm).
