Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q85-Q90):

NEW QUESTION # 85
When migrating workloads from AWS to OCI, which connectivity option generally offers the LOWEST latency and HIGHEST bandwidth for data transfer, assuming a direct, dedicated connection is financially viable?

A. Employing AWS Transit Gateway to connect to a VPN Gateway on OCI via a public IP address.
B. Utilizing a third-party cloud exchange provider to create a private network interconnect between AWS Direct Connect and OCI FastConnect.
C. Establishing an IPSec VPN tunnel over the public internet between the AWS Virtual Private Cloud (VPC) and the OCI Virtual Cloud Network (VCN).
D. Leveraging AWS Storage Gateway to replicate data to OCI Object Storage over the internet.

Answer: B

Explanation:
* Goal: Lowest latency, highest bandwidth for AWS-to-OCI migration.
* Option A: IPSec VPN over public internet has variable latency and limited bandwidth-incorrect.
* Option B: Third-party cloud exchange with Direct Connect and FastConnect offers a private, dedicated link, minimizing latency and maximizing bandwidth-correct.
* Option C: Storage Gateway over internet is slow and not dedicated-incorrect.
* Option D: Transit Gateway with VPN uses public internet, lacking performance-incorrect.
* Conclusion: Option B provides the best performance.
Oracle documentation notes:
* "A third-party cloud exchange provider can interconnect AWS Direct Connect and OCI FastConnect, delivering a private, high-bandwidth, low-latency connection."This validates Option B. Reference:
Multicloud Connectivity - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts
/multicloud.htm).

NEW QUESTION # 86
You are using the OCI Application Load Balancer (ALB) for your web application. You want to implement a blue/green deployment strategy to minimize downtime during application updates. You have two backend sets: 'blue' (the current version) and 'green' (the new version). What is the most efficient way to switch traffic from the 'blue' backend set to the 'green' backend set using the ALB's traffic management capabilities?

A. Update the listener to point directly to the 'green' backend set.
B. Use the ALB's routing rules to gradually shift traffic from the 'blue' backend set to the 'green' backend set based on a percentage weight.
C. Create a new listener that points to the 'green' backend set and delete the old listener.
D. Update the health check policy of the 'blue' backend set to mark all servers as unhealthy, forcing the ALB to send traffic to the 'green' backend set.

Answer: B

Explanation:
* Goal:Minimize downtime in blue/green deployment with ALB.
* ALB Capabilities:Supports weighted routing for gradual traffic shifts.
* Evaluate Options:
* A:Immediate switch risks downtime if 'green' fails; less efficient.
* B:Listener swap causes abrupt change; not optimal.
* C:Gradual shift with weights ensures smooth transition; most efficient.
* D:Forcing 'blue' unhealthy is disruptive and hacky; inefficient.
* Conclusion:Weighted routing provides the smoothest transition.
ALB supports blue/green via routing rules. The Oracle Networking Professional study guide states,
"Application Load Balancer's routing rules allow weighted traffic distribution between backend sets, enabling blue/green deployments with minimal downtime" (OCI Networking Documentation,Section: Load Balancer Routing). This method ensures stability during updates.

NEW QUESTION # 87
You have deployed a distributed application across OCI and Azure. You have established the OCI-Azure Interconnect. You are experiencing packet loss and performance degradation when transmitting large volumes of data between the two cloud providers. You have verified that the network devices on both sides are correctly configured. Which is NOT a typical root cause to investigate when troubleshooting performance issues across the OCI-Azure Interconnect?

A. Evaluate Network Security Groups (NSGs) and Security Lists on both OCI and Azure to verify that traffic is allowed between the necessary subnets and ports.
B. Inspect routing tables on both OCI and Azure to confirm that routes are correctly configured to direct traffic across the interconnect.
C. Assess the MTU (Maximum Transmission Unit) size settings on both OCI and Azure VNICs to ensure that fragmentation is not occurring.
D. Review the pricing tiers in OCI to ensure that the current OCI Compute usage has not exceeded maximum bandwidth limits.

Answer: D

Explanation:
* Problem:Packet loss and degradation over OCI-Azure Interconnect.
* Typical Causes:Security rules, routing, MTU mismatches.
* Evaluate Options:
* A:NSGs/Security Lists blocking traffic is a common issue; typical.
* B:Routing misconfiguration can drop packets; typical.
* C:Pricing tiers affect billing, not interconnect bandwidth; not typical.
* D:MTU mismatches cause fragmentation and loss; typical.
* Conclusion:Pricing tiers are unrelated to interconnect performance issues.
Interconnect performance issues stem from network configuration, not pricing. The Oracle Networking Professional study guide states, "Troubleshooting multi-cloud interconnects involves checking security rules, routing, and MTU settings, as these directly impact traffic flow" (OCI Networking Documentation, Section:
Multi-Cloud Connectivity). Pricing tiers influence resource limits, not interconnect bandwidth.

NEW QUESTION # 88
When applying Zero Trust principles to packet routing within OCI, what is the significance of using private endpoints instead of Service Gateways for accessing OCI services?

A. Private endpoints are only used for internet access.
B. Private endpoints automatically open all ports for service access.
C. Private endpoints restrict access to specific instances of a service, enhancing security.
D. Private endpoints eliminate the need for IAM policies.

Answer: C

Explanation:
* Context: Zero Trust requires strict access control.
* Option A: IAM policies are still required-incorrect.
* Option B: Private endpoints limit access to specific service instances, aligning with Zero Trust- correct.
* Option C: Ports are controlled by NSGs/security lists-incorrect.
* Option D: Private endpoints are for private access, not internet-incorrect.
* Conclusion: Option B enhances security.
Oracle states:
* "Private endpoints restrict access to specific OCI service instances, enhancing Zero Trust by limiting exposure compared to Service Gateways."This supports Option B. Reference:Private Endpoints - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/privateendpoints.htm).

NEW QUESTION # 89
Which of the following is a disadvantage of using a public internet-based VPN connection for migrating large datasets from another cloud provider to OCI?

A. VPN connections are not compatible with all OCI services
B. VPN connections are inherently less secure than dedicated private connections
C. The throughput of a VPN connection is limited by the available bandwidth and latency of the public internet
D. VPN connections cannot be automated using Infrastructure as Code (IaC) tools

Answer: C

Explanation:
* Objective: Identify a VPN disadvantage for large dataset migration.
* Option A: VPNs can be secure with IPSec; not inherently less secure-incorrect.
* Option B: VPNs are automatable with IaC (e.g., Terraform)-incorrect.
* Option C: Public internet limits VPN throughput due to bandwidth and latency variability-correct disadvantage.
* Option D: VPNs are compatible with OCI services-incorrect.
* Conclusion: Option C is the key disadvantage.
Oracle notes:
* "Public internet-based VPNs face throughput limitations due to bandwidth and latency variability, impacting large data migrations."This supports Option C. Reference:VPN Limitations - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPSec.htm#limitations).
