Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q121-Q126):

NEW QUESTION # 121
Which OCI logging feature allows you to correlate network traffic patterns from Flow Logs with application- level events from Service Logs for comprehensive troubleshooting?

  • A. Log Analytics
  • B. Log Streams
  • C. Log Export
  • D. Log Groups

Answer: A

Explanation:
* Objective: Correlate Flow Logs and Service Logs for troubleshooting.
* Option A: Log Groups organize logs but don't analyze correlations-incorrect.
* Option B: Log Analytics enables querying and visualizing logs from multiple sources, ideal for correlation-correct.
* Option C: Log Streams collect logs but don't correlate-incorrect.
* Option D: Log Export moves logs, not analyzes them-incorrect.
* Conclusion: Log Analytics is the best feature.
Oracle documentation confirms:
* "Log Analytics allows you to correlate and analyze logs from Flow Logs and Service Logs, providing insights for troubleshooting."This validates Option B. Reference:Log Analytics Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Logging/Concepts/loganalytics.htm).


NEW QUESTION # 122
You are configuring a VCN with multiple subnets for a customer. The security team requires that all instances have IPv6 addresses. You configure the VCN with an IPv6 ULA CIDR block of fc00:1:1::/48 and create two private subnets. After launching instances in the two private subnets, you notice that they only have IPv4 addresses assigned. You have not manually configured any IPv6 addresses on the instances themselves. What steps are necessary to ensure the instances automatically receive IPv6 addresses?

  • A. Ensure that SLAAC (Stateless Address Autoconfiguration) is enabled on the operating system of the instances within the two subnets.
  • B. Make sure the "Assign public IPv4 address" option is not selected during instance creation. This will force the instance to default to IPv6 allocation.
  • C. IPv6 address assignment is only supported on instances launched in public subnets.
  • D. No further steps are needed. Instances will automatically receive IPv6 addresses within the configured subnets upon launch.

Answer: A

Explanation:
* Problem:Instances lack IPv6 addresses despite VCN IPv6 configuration.
* OCI IPv6 Behavior:IPv6 requires subnet enablement and OS support via SLAAC.
* Evaluate Options:
* A:Incorrect. OCI doesn't auto-assign IPv6 without OS configuration.
* B:Correct. SLAAC must be enabled on the instance OS for auto-assignment.
* C:Incorrect. IPv6 works in both public and private subnets.
* D:Incorrect. IPv4 and IPv6 assignments are independent.
* Conclusion:Enabling SLAAC on the OS ensures automatic IPv6 assignment.
IPv6 in OCI relies on SLAAC for automatic address assignment. The Oracle Networking Professional study guide states, "To enable IPv6 on instances, the VCN and subnet must have IPv6 CIDR blocks, and the instance OS must support SLAAC to automatically configure IPv6 addresses" (OCI Networking Documentation, Section: IPv6 Configuration). Without SLAAC, instances default to IPv4 only.


NEW QUESTION # 123
You are automating the deployment of a highly available OKE cluster across multiple availability domains (ADs) using Terraform. The OKE cluster needs to communicate with a database service running on a Compute instance in a separate private subnet within the same VCN. During the Terraform deployment, you encounter an error indicating that the Kubernetes pods cannot resolve the private IP address of the database instance. You've verified that DNS resolution works correctly for other resources within the VCN. What is the MOST probable reason for this DNS resolutionfailure?

  • A. The OKE cluster was created with a public endpoint only, and therefore cannot resolve private IP addresses.
  • B. The CoreDNS pods within the OKE cluster are not configured to use the VCN's DNS resolver.
  • C. The OKE cluster's node pool subnet is not associated with a route table that has a rule for the VCN's DNS resolver.
  • D. The security list associated with the database subnet does not allow ingress traffic from the OKE cluster' s node pool subnet on port 53 (DNS).

Answer: B

Explanation:
* Problem: OKE pods can't resolve private DB IP despite VCN DNS working.
* Option A: CoreDNS in OKE must forward to VCN's resolver for private IPs; misconfiguration is a common issue-correct.
* Option B: Security lists block traffic, not resolution; VCN DNS isn't hosted on the DB-incorrect.
* Option C: Public endpoint affects API access, not internal DNS-incorrect.
* Option D: Route tables don't control DNS resolution-incorrect.
* Conclusion: Option A is the most probable cause.
Oracle notes:
* "CoreDNS in OKE must be configured to forward queries to the VCN's DNS resolver (.169 address) for private IP resolution."This supports Option A. Reference:OKE DNS Configuration - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengdns.htm).


NEW QUESTION # 124
Your company utilizes a hybrid cloud architecture, connecting its on-premises network to an OCIVCN using a FastConnect private peering connection. You need to ensure that instances within a specific subnet in the VCN can only communicate with resources in a designated IP address range within the on-premises network.
What is the MOST effective way to achieve this specific network isolation?

  • A. Create a custom route table for the subnet with a route rule pointing to the Dynamic Routing Gateway (DRG) and configure network security groups (NSGs) to limit traffic to the specified on-premises IP address range.
  • B. Modify the VCN's default security list to restrict traffic to the on-premises IP address range.
  • C. Configure an Internet Gateway for the subnet with a route rule to the on-premises network.
  • D. Configure a Local Peering Gateway (LPG) for the subnet to route traffic to the on-premises network.

Answer: A

Explanation:
* Goal: Restrict subnet traffic to a specific on-premises IP range via FastConnect.
* Option A: Internet Gateway is for public access, not FastConnect-incorrect.
* Option B: Default security list applies broadly, lacking granularity; NSGs are more effective-less optimal.
* Option C: Custom route table with DRG ensures FastConnect routing; NSGs provide precise, instance- level traffic restriction-correct.
* Option D: LPG is for same-region VCN peering, not on-premises-incorrect.
* Conclusion: Option C is the most effective method.
Oracle notes:
* "Use a custom route table with a DRG route rule for FastConnect traffic. NSGs offer granular control to restrict traffic to specific IP ranges."This supports Option C. Reference:FastConnect and NSG Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm & docs.oracle.com/en-us/iaas/Content/Network/Concepts/NSGs.htm).


NEW QUESTION # 125
Which aspect of OCI's security framework is essential for continuous monitoring and verification of packet flows, a core requirement of Zero Trust Packet Routing?

  • A. Default security lists
  • B. Public IP address assignments
  • C. Static routing configurations
  • D. Flow logs and audit trails

Answer: D

Explanation:
* Goal: Support Zero Trust with packet flow monitoring.
* Option A: Static routing defines paths, not monitoring-incorrect.
* Option B: Security lists control access, not monitor-incorrect.
* Option C: Flow logs track traffic; audit trails log actions-essential for Zero Trust-correct.
* Option D: Public IPs enable access, not monitoring-incorrect.
* Conclusion: Option C is essential.
Oracle states:
* "Flow logs and audit trails provide continuous monitoring and verification of packet flows, critical for Zero Trust Packet Routing."This supports Option C. Reference:Zero Trust in OCI - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Concepts/zerotrust.htm).
