Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q43-Q48):

NEW QUESTION # 43
You have configured DNSSEC for your domain hosted on OCI DNS. You understand the importance of regularly rotating your Key Signing Key (KSK) to maintain security best practices. Which of the following statements regarding KSK rotation in OCI DNS is TRUE?

A. KSK rotation is a fully automated process managed by OCI DNS and requires no manual intervention.
B. KSK rotation is not supported in OCI DNS; you must migrate your DNS zone to another provider if you require KSK rotation.
C. You must manually generate a new KSK and ZSK pair and upload them to OCI DNS to initiate a KSK rotation.
D. KSK rotation in OCI DNS involves enabling a "KSK Rollover" feature, which automatically handles the key rotation process while minimizing disruption to DNS resolution.

Answer: D

Explanation:
* Objective: Identify the true statement about KSK rotation in OCI DNS.
* Option A: OCI DNS automates much of the process but requires user initiation, not fully automated- incorrect.
* Option B: OCI DNS generates keys internally; manual generation and upload aren't required- incorrect.
* Option C: OCI DNS offers a "KSK Rollover" feature that, once enabled, automates the rotation process, ensuring minimal disruption-correct.
* Option D: KSK rotation is supported via the rollover feature-incorrect.
* Conclusion: Option C accurately describes OCI DNS KSK rotation.
Oracle documentation confirms:
* "OCI DNS supports KSK rotation through the KSK Rollover feature. Enable it to automatically rotate keys while maintaining DNS resolution continuity."This validates Option C. Reference:DNSSEC in OCI DNS - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/DNS/Tasks/managingdnssec.htm).

NEW QUESTION # 44
Your company requires a dedicated, high-bandwidth, and low-latency connection between your on-premises data center and your OCI tenancy. You need to connect to OCI in a region where Oracle is not directly present with a FastConnect location. You also want to leverage a third-party network provider for this connectivity. Which FastConnect connectivity model would be the most suitablefor your requirements?

A. FastConnect Partner
B. FastConnect Public Peering
C. FastConnect Direct Cross-Connect
D. FastConnect Hosted

Answer: A

Explanation:
* Requirements:Dedicated, high-bandwidth, low-latency, no Oracle FastConnect location, third-party provider.
* FastConnect Models:
* Direct Cross-Connect:Requires Oracle location; unsuitable.
* Partner:Uses third-party network to Oracle; fits scenario.
* Hosted:Third-party hosts, less common term; less precise.
* Public Peering:Internet-based; doesn't meet dedicated need.
* Evaluate Options:
* A:Needs Oracle presence; incorrect.
* B:Third-party to Oracle; correct.
* C:Similar but less standard term; less optimal.
* D:Public internet; incorrect.
* Conclusion:FastConnect Partner is most suitable.
Partner model extends FastConnect reach. The Oracle Networking Professional study guide states,
"FastConnect Partner model leverages third-party providers to connect on-premises networks to OCI in regions without direct Oracle FastConnect locations" (OCI Networking Documentation, Section: FastConnect Models). This ensures dedicated connectivity.

NEW QUESTION # 45
You are designing a VCN in OCI to host a multi-tenant SaaS application. Each tenant requires a separate and isolated network segment for security and regulatory compliance. You are using a large CIDR block for the VCN. What is the most efficient procedural method for achieving network segmentation and isolation for each tenant, considering IP address utilization and ease of management?

A. Create a separate private subnet for each tenant within the same VCN, utilizing Network Security Groups (NSGs) and routing rules to enforce isolation.
B. Create a separate compartment for each tenant and place all network resources within the tenant's compartment. Use NSGs and routing rules for isolation.
C. Create a separate VCN for each tenant.
D. Create a separate virtual machine (VM) for each tenant and rely on host-based firewalls for isolation.

Answer: A

Explanation:
* Requirements:Isolated segments, efficient IP use, easy management.
* Options Analysis:
* A:Separate VCNs waste IPs, high overhead; inefficient.
* B:Subnets with NSGs optimize IP use, simplify control; correct.
* C:Compartments are for IAM, not network isolation; incorrect.
* D:VM firewalls are complex, less secure; unsuitable.
* Conclusion:Subnets with NSGs are most efficient.
Subnets and NSGs provide tenant isolation. The Oracle Networking Professional study guide states, "For multi-tenant applications, use separate private subnets within a VCN and enforce isolation with NSGs and routing rules, optimizing IP utilization and management" (OCI Networking Documentation, Section: VCN Design). This balances security and efficiency.

NEW QUESTION # 46
You are setting up a FastConnect connection between your on-premises data center and OCI. You need to configure BGP to exchange routing information. You require OCI to always prefer the FastConnect path for traffic destined to your on-premises network, even if OCI learns about the same prefixes via the public internet. Which BGP attribute should you configure on the OCI side of the FastConnect connection to achieve this?

A. Advertise a more specific (longer prefix length) route via FastConnect.
B. Configure MED to a lower value for routes advertised via FastConnect.
C. Increase the Local Preference for routes learned via FastConnect.
D. Decrease the AS Path length for routes learned via FastConnect.

Answer: C

Explanation:
* Goal:Prefer FastConnect routes over public internet in OCI.
* BGP Attributes:
* Local Preference:Higher value prefers a path within an AS.
* AS Path:Shorter path preferred, but manipulated on sender side.
* Prefix Length:More specific wins, but not controllable here.
* MED:Influences inbound traffic, not OCI preference.
* Evaluate Options:
* A:Higher Local Preference ensures FastConnect priority; correct.
* B:AS Path is set by on-premises, not OCI; incorrect.
* C:Prefix specificity is on-premises controlled; incorrect.
* D:MED affects on-premises, not OCI; incorrect.
* Conclusion:Local Preference is the right attribute.
Local Preference controls route preference in BGP. The Oracle Networking Professional study guide states,
"To prioritize FastConnect routes in OCI, increase the Local Preference for routes learned via the FastConnect virtual circuit over other paths" (OCI Networking Documentation, Section: BGP Configuration). This ensures OCI prefers the private path.

NEW QUESTION # 47
When migrating workloads requiring high availability and redundancy for on-premises connectivity to OCI, which approach is recommended?

A. Internet Gateway with multiple public IPs
B. Dual FastConnect connections with diverse paths
C. Single FastConnect connection
D. Site-to-Site VPN over a single internet connection

Answer: B

Explanation:
* Requirements: HA and redundancy for on-premises-to-OCI connectivity.
* Option A: Single FastConnect lacks redundancy-incorrect.
* Option B: Single VPN over internet has no redundancy and poor performance-incorrect.
* Option C: Dual FastConnect with diverse paths ensures HA and redundancy via separate routes- correct.
* Option D: Internet Gateway with public IPs isn't dedicated or redundant-incorrect.
* Conclusion: Option C is the recommended approach.
Oracle advises:
* "For high availability, use dual FastConnect connections with diverse paths to eliminate single points of failure in hybrid connectivity."This supports Option C. Reference:FastConnect High Availability - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#ha).
