Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q24-Q29):

NEW QUESTION # 24
Your organization is deploying a critical database application on OCI. To ensure high availability, you have deployed the database instances across multiple availability domains (ADs) within asingle region. You need to distribute client connections to the database instances and ensure that the load balancer can handle long- lived TCP connections with minimal overhead. Session persistence is not required. Which OCI load balancing solution would you choose in this scenario to minimize latency and connection establishment overhead?

A. Network Load Balancer with TCP health checks.
B. Application Load Balancer with HTTP health checks.
C. Application Load Balancer with TCP health checks.
D. Flexible Load Balancer with HTTP health checks.

Answer: A

Explanation:
* Requirements:Low-latency, minimal overhead for TCP connections, no session persistence.
* Load Balancer Types:
* Application Load Balancer (ALB):Layer 7, higher overhead, suited for HTTP/HTTPS.
* Network Load Balancer (NLB):Layer 4, low overhead, ideal for TCP/UDP.
* Evaluate Options:
* A:ALB with HTTP checks is for HTTP traffic, adds overhead; unsuitable.
* B:NLB with TCP checks is optimized for TCP, low latency; best fit.
* C:ALB with TCP checks still has Layer 7 overhead; less efficient.
* D:"Flexible Load Balancer" isn't a specific OCI service; incorrect.
* Conclusion:NLB minimizes latency and overhead for TCP connections.
The Network Load Balancer is designed for high-performance TCP scenarios. The Oracle Networking Professional study guide states, "Network Load Balancer operates at Layer 4, providing low-latency, high- throughput load balancing for TCP/UDP traffic with minimal overhead, ideal for database connections" (OCI Networking Documentation, Section: Load Balancing). TCP health checks ensure instance availability without session persistence complexity.

NEW QUESTION # 25
You are troubleshooting an issue where a compute instance in a private subnet within a VCN cannot reach OCI Object Storage. You have verified that a Service Gateway is configured for the VCN and that the route table associated with the subnet has a route rule directing traffic for OCI Services to the Service Gateway.
However, the instance still cannot connect. What is the MOST likely cause of the problem?

A. The instance requires a public IP address to access OCI Object Storage.
B. The Service Gateway is not configured to allow access to OCI Object Storage.
C. The instance is not configured with the Oracle Cloud Agent.
D. The security list or network security group associated with the subnet or instance is not configured to allow outbound traffic to the OCI Object Storage service CIDR block.

Answer: D

Explanation:
* Problem: Instance in private subnet can't reach Object Storage despite Service Gateway and routing.
* Option A: Service Gateway enables private access; public IP isn't required-incorrect.
* Option B: Security lists/NSGs act as firewalls; if outbound traffic to Object Storage CIDR isn't allowed, connectivity fails-most likely and correct.
* Option C: Service Gateway defaults to all OCI services unless restricted; less likely given setup verification-incorrect.
* Option D: Oracle Cloud Agent is for management, not connectivity-incorrect.
* Conclusion: Option B is the most probable cause.
Oracle states:
* "For private access to Object Storage via a Service Gateway, ensure security lists or NSGs allow outbound traffic to the Object Storage CIDR block."This supports Option B. Reference:Service Gateway Troubleshooting - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks
/servicegateway.htm#troubleshooting).

NEW QUESTION # 26
You are designing a highly available and scalable e-commerce application on OCI. The application requires load balancing for both HTTP/HTTPS traffic and TCP-based microservices communication. You need a solution that provides advanced traffic management capabilities, including content-based routing and path- based routing, and can also protect against common web exploits. Which OCI load balancing offering is the most suitable for this scenario, considering the need for web application firewall (WAF) integration?

A. Flexible Load Balancer
B. Load Balancing as a Service (LBaaS)
C. Network Load Balancer
D. Application Load Balancer

Answer: D

Explanation:
* Requirements:HTTP/HTTPS + TCP, advanced routing, WAF protection.
* Load Balancers:
* NLB:Layer 4, no HTTP routing or WAF; unsuitable.
* ALB:Layer 7, supports routing and WAF; fits perfectly.
* Flexible LB:Not a specific OCI service; incorrect.
* LBaaS:Generic term, not a product; incorrect.
* Evaluate Options:
* A:Lacks Layer 7 and WAF; incorrect.
* B:Meets all needs with ALB + WAF; correct.
* C:Non-existent; incorrect.
* D:Too vague; incorrect.
* Conclusion:Application Load Balancer is most suitable.
ALB supports complex e-commerce needs. The Oracle Networking Professional study guide states,
"Application Load Balancer operates at Layer 7, offering content-based and path-based routing, and integrates with OCI WAF for exploit protection" (OCI Networking Documentation, Section: Application Load Balancer). This aligns with all requirements.

NEW QUESTION # 27
Your company has a FastConnect circuit established between your on-premises data center and OCI.
However, you have a specific regulatory requirement to encrypt all traffic, even over dedicated connections like FastConnect. You need to implement IPSec encryption without significantly impacting the available bandwidth of your FastConnect circuit. Which is the most effective approach to implement IPSec encryption over your existing FastConnect circuit, while maintaining high bandwidth?

A. Deploy virtual firewall appliances within OCI and your on-premises network and configure IPSec tunnels between them, routing all traffic through the firewalls. Use a high-security encryption algorithm like AES-256.
B. Terminate IPSec VPN on compute instances in a public subnet on the OCI side.
C. Establish a second, separate Site-to-Site VPN connection to OCI over the public internet, and route all sensitive traffic over this VPN, while routing non-sensitive traffic over the FastConnect circuit.
D. Configure a Site-to-Site VPN using the OCI Dynamic Routing Gateway (DRG) over theFastConnect virtual circuit. Use a low-overhead encryption algorithm like AES-GCM.

Answer: D

Explanation:
* Requirements:Encrypt FastConnect traffic with minimal bandwidth impact.
* IPSec Options:
* DRG VPN:Native OCI solution over FastConnect.
* Firewall Appliances:Adds overhead and complexity.
* Compute Instances:Resource-intensive, not scalable.
* Internet VPN:Uses public internet, against requirements.
* Evaluate Options:
* A:DRG VPN with AES-GCM (low-overhead encryption) leverages FastConnect; optimal.
* B:Firewalls with AES-256 add overhead, reducing bandwidth; less effective.
* C:Compute-based VPN is inefficient and public-facing; unsuitable.
* D:Public internet VPN violates privacy requirement; incorrect.
* Conclusion:DRG VPN with AES-GCM is the most effective solution.
OCI supports IPSec over FastConnect via DRG. The Oracle Networking Professional study guide explains,
"A Site-to-Site VPN over FastConnect using the DRG provides encrypted traffic with low-overhead algorithms like AES-GCM, maintaining high bandwidth" (OCI Networking Documentation, Section:
FastConnect with VPN). This meets regulatory and performance needs efficiently.

NEW QUESTION # 28
Your company is setting up a FastConnect connection with a provider. You have purchased a port from the provider, and they are requesting information to set up the connection to Oracle Cloud Infrastructure. They specifically require information to configure the VLANs. What information regarding VLAN configuration is ESSENTIAL for them to successfully establish the FastConnect circuit?

A. Your Oracle Cloud Identifier (OCID) and compartment ID.
B. A single unused VLAN ID, your BGP ASN, and the BGP peering IP addresses you want to use.
C. The MTU (Maximum Transmission Unit) size for all VNICs in your OCI tenancy.
D. The list of all VCN CIDR blocks and their associated tags.

Answer: B

Explanation:
* Requirement: Provide VLAN config info for FastConnect setup.
* Option A: CIDR blocks are for routing, not VLAN setup-incorrect.
* Option B: VLAN ID defines the circuit, BGP ASN and peering IPs establish routing-essential and correct.
* Option C: MTU is a performance setting, not required for VLAN config-incorrect.
* Option D: OCID and compartment ID are for OCI management, not provider setup-incorrect.
* Conclusion: Option B provides the necessary VLAN configuration details.
Oracle states:
* "For FastConnect, provide the provider with a VLAN ID, your BGP ASN, and BGP peering IPs to configure the virtual circuit."This confirms Option B. Reference:FastConnect Configuration - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#providerconfig).
