Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q65-Q70):

NEW QUESTION # 65
In a multi-tier application environment with geographically dispersed teams requiring access to private resources, how can an OCI Bastion service be optimized to reduce latency for remote users?

A. Deploying a single Bastion host in the primary application region.
B. Implementing Bastion hosts in multiple regions closer to user locations.
C. Configuring a Bastion service with a public load balancer.
D. Using dynamic port forwarding to allow direct connections to private resources.

Answer: B

Explanation:
* Objective: Reduce latency for remote users accessing private resources via Bastion.
* Option A: Single Bastion increases latency for distant users-incorrect.
* Option B: Multiple regional Bastions minimize latency by proximity-correct.
* Option C: Dynamic port forwarding doesn't address geographic latency-incorrect.
* Option D: Load balancer aids HA, not latency reduction-incorrect.
* Conclusion: Option B optimizes latency.
Oracle notes:
* "Deploy Bastion hosts in multiple regions to reduce latency for geographically dispersed users accessing private resources."This supports Option B. Reference:Bastion Service Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Bastion/Concepts/bastionoverview.htm).

NEW QUESTION # 66
Your company is migrating several applications to OCI and requires a highly available and resilient VPN connection between your on-premises network and OCI. You need to ensure that if one VPN tunnel fails, traffic automatically fails over to a backup tunnel with minimal disruption. Which configuration would BEST achieve high availability and automatic failover for your OCI Site-to-Site VPN connection?

A. Configure a single VPN connection with two tunnels, ensuring that both tunnels use different CPE IP addresses on the on-premises side.
B. Configure two separate VPN connections, each with a single tunnel, pointing to different CPE IP addresses on the on-premises side. Advertise the same prefixes over both VPN connections using BGP.
C. Configure a single VPN connection with a single tunnel and rely on the underlying OCI infrastructure for automatic failover.
D. Configure a single VPN connection with two tunnels using the same CPE IP address.

Answer: A

Explanation:
* Understand the Requirement: The goal is high availability (HA) and automatic failover for a Site-to- Site VPN between an on-premises network and OCI with minimal disruption.
* Evaluate Option A: A single VPN connection with one tunnel lacks redundancy. If the tunnel fails, there's no failover mechanism, as OCI doesn't inherently provide automatic failover for a single tunnel.
This is a single point of failure.
* Evaluate Option B: A single VPN connection with two tunnels using different CPE IP addresses leverages OCI's IPSec VPN capabilities. OCI supports multiple tunnels per VPN connection, and using distinct CPE IPs (e.g., via different ISPs or devices) ensures that if one tunnel fails (due to ISP or CPE failure), the second tunnel remains active. OCI's Dynamic Routing Gateway (DRG) automatically reroutes traffic to the active tunnel using IKE and IPSec health checks.
* Evaluate Option C: Two separate VPN connections, each with one tunnel and different CPE IPs, also provide HA. Using BGP, routes are advertised redundantly. However, managing two VPN connections is more complex than a single connection with two tunnels, and BGP failover might introduce slight delays compared to IPSec tunnel failover.
* Evaluate Option D: Two tunnels with the same CPE IP address within one VPN connection don't provide true HA. If the CPE or its ISP fails, both tunnels fail, as they share a single point of failure.
* Conclusion: Option B is the simplest, most resilient configuration that ensures automatic failover with minimal disruption using OCI's native VPN capabilities.
OCI's Site-to-Site VPN supports multiple tunnels within a single IPSec connection for redundancy.
According to the Oracle Help Center:
* "You can configure multiple tunnels for a single IPSec connection to provide redundancy. OCI uses IKE (Internet Key Exchange) to monitor tunnel health and automatically fails over to an active tunnel if one becomes unavailable."
* "For maximum availability, use different CPE public IP addresses for each tunnel (e.g., different ISPs or devices)."This aligns with Option B, ensuring HA without the complexity of separate VPN connections or BGP. Reference:Site-to-Site VPN Overview - Oracle Help Center(docs.oracle.com/en-us
/iaas/Content/Network/Tasks/settingupIPSec.htm).

NEW QUESTION # 67
You are troubleshooting an issue where legitimate users are occasionally blocked by your OCI WAF, which is configured in "Detection" mode. You need to identify the specific WAF rules that are triggering these false positives and adjust them without disrupting legitimate traffic. Which approach offers the most efficient way to diagnose and resolve this issue?

A. Whitelist the IP addresses of the affected users.
B. Increase the sensitivity level of the entire WAF configuration.
C. Analyze the OCI WAF logs in OCI Logging Analytics, focusing on the rule IDs associated with blocked requests. Then, move the specific rule to "log only".
D. Disable all WAF rules and then gradually re-enable them one by one until the issue reappears.

Answer: C

Explanation:
* Problem Scope:Identify and adjust WAF rules causing false positives in Detection mode without disrupting traffic.
* Detection Mode Behavior:Logs potential violations without blocking, allowing analysis.
* Evaluate Options:
* A:Use OCI Logging Analytics to pinpoint rule IDs from logs, then set rules to "log only" for testing; efficient and non-disruptive.
* B:Disabling all rules risks security and is time-consuming; inefficient.
* C:Increasing sensitivity worsens false positives; counterproductive.
* D:Whitelisting IPs is a temporary fix, not scalable or diagnostic; unsuitable.
* Conclusion:Logging analysis with rule adjustment is the most efficient approach.
OCI WAF logs provide detailed insights for troubleshooting. The Oracle Networking Professional study guide states, "In Detection mode, WAF logs all triggered rules, which can be analyzed in OCI Logging Analytics to identify false positives. Rules can then be adjusted to 'log only' to refine policies without affecting traffic" (OCI Networking Documentation, Section: Web Application Firewall). This method ensures precision and minimal disruption.

NEW QUESTION # 68
You have configured an IPSec VPN tunnel over your FastConnect circuit to OCI. You are experiencing intermittent connectivity issues and notice that the VPN tunnel is flapping (frequently going up and down).
You have verified the IKE and IPSec configuration and confirmed that the security policies are correct.
Which is a LESS likely cause of the VPN tunnel flapping when using IPSec over FastConnect, compared to using IPSec over the public internet?

A. MTU (Maximum Transmission Unit) misconfiguration leading to fragmentation.
B. Mismatched pre-shared keys or incorrect IKE/IPSec parameters.
C. Issues with network congestion or packet loss.
D. BGP route flapping or instability.

Answer: C

Explanation:
* Context: Tunnel flapping over FastConnect vs. public internet.
* Option A: Congestion/packet loss is less likely over FastConnect's dedicated link than the unpredictable public internet-correct.
* Option B: Mismatched keys/parameters would prevent tunnel establishment, not flapping-equally likely in both.
* Option C: MTU issues cause fragmentation in both scenarios-equally likely.
* Option D: BGP flapping is more relevant with FastConnect's dynamic routing-more likely here.
* Conclusion: Option A is less likely over FastConnect.
Oracle notes:
* "FastConnect provides a stable, dedicated connection, reducing congestion and packet loss compared to public internet VPNs."This supports Option A. Reference:IPSec over FastConnect - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPSec.htm#fastconnect).

NEW QUESTION # 69
You are managing a critical application hosted on OCI. To enhance security, you have enabled DNSSEC for your domain using OCI DNS. You want to automate the process of monitoring the health and validity of your DNSSEC configuration and receive alerts if any issues are detected. Which OCI service can be MOST effectively used for this DNSSEC monitoring purpose?

A. OCI Vulnerability Scanning Service.
B. OCI Logging Analytics.
C. OCI Audit Service.
D. OCI Monitoring Service.

Answer: D

Explanation:
* Goal: Automate DNSSEC health monitoring with alerts.
* Option A: Vulnerability Scanning is for compute instances, not DNSSEC-incorrect.
* Option B: Monitoring Service tracks metrics and logs, supports custom DNSSEC metrics, and provides alarms-correct.
* Option C: Audit Service logs API calls, not DNSSEC health-incorrect.
* Option D: Logging Analytics analyzes logs but lacks direct alerting-less effective than Monitoring.
* Conclusion: Option B is the most effective for automated monitoring and alerts.
Oracle documentation notes:
* "OCI Monitoring Service allows you to monitor metrics and logs, including DNSSEC-related data, and set alarms for proactive notifications."This supports Option B. Reference:Monitoring Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Monitoring/Concepts/monitoringoverview.
