Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q22-Q27):

NEW QUESTION # 22
You are designing a hybrid cloud solution where sensitive data must be transferred between your on-premises data center and an OCI VCN. You require a dedicated, private connection with guaranteed bandwidth and low latency. In addition to FastConnect, what additional product would you implement to achieve encryption of the traffic traversing the FastConnect link and to ensure data confidentiality?

A. MACsec
B. Oracle Cloud Infrastructure Vault
C. IPSec VPN
D. OCI Bastion

Answer: A

Explanation:
* Requirement Analysis: The solution needs a private, high-bandwidth, low-latency connection (provided by FastConnect) with encryption for data confidentiality.
* Option A (IPSec VPN): IPSec encrypts traffic at Layer 3 over public or private networks. While feasible over FastConnect, it's redundant since FastConnect is already private, adding unnecessary overhead and complexity.
* Option B (OCI Vault): Vault manages encryption keys and secrets but doesn't encrypt traffic itself- only supports application-level encryption, not link-level-incorrect.
* Option C (MACsec): MACsec (Media Access Control Security) provides Layer 2 encryption for Ethernet traffic, ideal for securing FastConnect's dedicated link directly between devices, ensuring confidentiality without higher-layer overhead-correct.
* Option D (OCI Bastion): Bastion secures remote access to VCN resources, not link encryption- incorrect.
* Conclusion: MACsec enhances FastConnect with efficient, link-level encryption, meeting all requirements.
Oracle documentation states:
* "MACsec provides Layer 2 encryption for FastConnect, securing Ethernet traffic between on-premises and OCI infrastructure. It's ideal for ensuring confidentiality over dedicated connections."This supports Option C as the best additional product. Reference:FastConnect Security Options - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#security).

NEW QUESTION # 23
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. The list of all VCN CIDR blocks and their associated tags.
C. A single unused VLAN ID, your BGP ASN, and the BGP peering IP addresses you want to use.
D. The MTU (Maximum Transmission Unit) size for all VNICs in your OCI tenancy.

Answer: C

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).

NEW QUESTION # 24
A company has deployed a VCN in OCI with multiple subnets. Security requirements dictate that instances in different subnets within the same VCN should not be able to directly communicate with each other unless explicitly permitted. You are tasked with implementing this policy. What is the most appropriate approach to meet this requirement?

A. Configure network security groups (NSGs) for each subnet, defining strict ingress and egress rules that only allow the necessary traffic.
B. Create separate VCNs for each subnet.
C. Remove the default route rule in the VCN's route table that allows traffic between subnets.
D. Configure a stateful firewall in front of the VCN and configure the rules to deny inter-subnet traffic.

Answer: A

Explanation:
* Requirement:Restrict inter-subnet communication unless permitted.
* Options Analysis:
* A:Removing default route breaks all routing, overly restrictive; incorrect.
* B:Separate VCNs are excessive, complex; less practical.
* C:NSGs provide granular, explicit control; optimal approach.
* D:External firewall adds complexity, not VCN-native; inefficient.
* NSG Advantage:Instance-level rules enforce policy within VCN.
* Conclusion:NSGs are the most appropriate solution.
NSGs enable precise security within a VCN. The Oracle Networking Professional study guide states,
"Network Security Groups (NSGs) allow you to define strict ingress and egress rules for instances, ensuring inter-subnet communication is explicitly permitted as per security policies" (OCI Networking Documentation, Section: Network Security Groups). This is more efficient than VCN separation or external firewalls.

NEW QUESTION # 25
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 Monitoring Service.
B. OCI Logging Analytics.
C. OCI Audit Service.
D. OCI Vulnerability Scanning Service.

Answer: A

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.
htm).

NEW QUESTION # 26
Your security policy mandates that all communication between your compute instances in a private subnet and OCI Object Storage must be authenticated and authorized using IAM policies and not rely on public IP addresses. Which OCI networking feature is the most appropriate to satisfy this requirement?

A. Private Subnet with a Service Gateway and IAM rules.
B. Public Subnet with an Internet Gateway and IAM rules.
C. Public Subnet with a Network Firewall and IAM rules.
D. Private Subnet with a NAT Gateway and IAM rules.

Answer: A

Explanation:
* Requirement: Private, IAM-secured access to Object Storage.
* Option A: Public subnet with Internet Gateway uses public IPs-violates policy.
* Option B: NAT Gateway is for internet access, not private OCI services-incorrect.
* Option C: Service Gateway enables private access to Object Storage, paired with IAM for auth- correct.
* Option D: Public subnet with firewall still relies on public IPs-incorrect.
* Conclusion: Option C meets all requirements.
Oracle states:
* "Use a Service Gateway for private access to OCI Object Storage from a private subnet, with IAM policies for authentication and authorization."This supports Option C. Reference:Service Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/servicegateway.
htm).
