Oracle Cloud Infrastructure 2025 Networking Professional 1z0-1124-25 Prüfungsfragen mit Lösungen (Q119-Q124):

119. Frage
You are designing a hybrid cloud environment where multiple VCNs in OCI need to communicate with your on-premises network. You are using a single Dynamic Routing Gateway (DRG) to connect to your on- premises network via FastConnect. You want to ensure that each VCN is isolated from the others and that traffic between VCNs must pass through your on-premises security appliances for inspection. How should you configure the DRG attachments and route tables to enforce this security policy?

A. Attach each VCN directly to the FastConnect using IPSec VPN tunnels, bypassing the DRG entirely to ensure all traffic flows through the on-premises security appliances.
B. Attach all VCNs and the FastConnect to the DRG. Configure the DRG route table associated with each VCN attachment to route all traffic destined for other VCNs to the FastConnect attachment. Configure the FastConnect DRG route table to route traffic destined to each VCN to the corresponding VCN attachment.
C. Attach all VCNs and the FastConnect to the DRG. Configure static routes on each VCN's route table pointing to the DRG for any subnet not within the VCN. Enable the "Transit Routing" feature on the DRG to allow inter-VCN communication.
D. Attach each VCN to the DRG using a Local Peering Gateway (LPG) and then attach one VCN to FastConnect. Configure routes so that traffic traverses from LPG to LPG through the on-premises network.

Antwort: B

Begründung:
* Requirements:VCN isolation, inter-VCN traffic via on-premises appliances.
* DRG Role:Central hub for VCN and FastConnect connectivity.
* Evaluate Options:
* A:DRG routes inter-VCN traffic via FastConnect to on-premises; meets isolation and inspection needs.
* B:Transit Routing allows direct VCN-to-VCN communication, bypassing on-premises; incorrect.
* C:Bypassing DRG with VPNs is complex and unsupported; incorrect.
* D:LPG is for intra-region peering, not DRG-to-FastConnect; incorrect.
* Conclusion:Option A enforces the policy via DRG route tables.
DRG route tables control traffic flow. The Oracle Networking Professional study guide states, "To force inter- VCN traffic through an on-premises network via FastConnect, configure DRG route tables to route VCN- destined traffic to the FastConnect attachment, ensuring isolation and inspection" (OCI Networking Documentation, Section: DRG Routing). This setup leverages a single DRG effectively.

120. Frage
A company wants to leverage a best-of-breed approach for their application stack. They plan to use OCI for its Autonomous Database, Azure for its container orchestration (AKS), and AWS for its object storage (S3).
Considering cost optimization and minimizing data egress charges, which strategy is the MOST efficient for transferring large datasets between these services?

A. Using Storage Gateway service on each cloud and replicate data from one gateway to the other
B. Utilizing a third-party data integration platform that is strategically located at a network peering point between OCI, Azure, and AWS
C. Establishing a hub-and-spoke model, using a central cloud provider as the data transfer hub, incurring egress charges from each cloud to the hub and then ingress charges from the hub to the destination cloud
D. Moving data directly between OCI Autonomous Database, Azure AKS, and AWS S3 using public internet, as this is the most cost-effective option

Antwort: B

Begründung:
* Goal: Efficient, cost-optimized data transfer minimizing egress charges.
* Option A: Public internet incurs high egress costs-incorrect.
* Option B: Hub-and-spoke doubles egress/ingress charges-less efficient.
* Option C: Third-party platform at peering points reduces egress by leveraging direct connections- correct.
* Option D: Storage Gateway is for hybrid, not multicloud efficiency-incorrect.
* Conclusion: Option C is the most efficient strategy.
Oracle states:
* "A third-party integration platform at peering points minimizes egress charges by using direct interconnects for multicloud data transfers."This validates Option C. Reference:Multicloud Cost Optimization - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/multicloud.
htm#costoptimization).

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

Antwort: C

Begründung:
* 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).

122. Frage
Your security team has mandated that all traffic to Oracle Cloud Infrastructure Object Storage must be encrypted end-to-end and must not be routed over the public internet. You are designing asolution where compute instances within a private subnet will frequently upload and download data from Object Storage.
Which of the following options provides the most secure and compliant solution?

A. Configure a Service Gateway to Object Storage and ensure all API calls to Object Storage are made over HTTPS.
B. Configure a NAT Gateway for the instances and enable encryption in transit using HTTPS for all Object Storage API calls.
C. Configure a Service Gateway to Object Storage and enable encryption at rest on the Object Storage bucket.
D. Configure a Private Endpoint to Object Storage and ensure all API calls to Object Storage are made over HTTPS.

Antwort: A

Begründung:
* Requirements:End-to-end encryption, no public internet for Object Storage access.
* Options Analysis:
* Service Gateway:Private access to Object Storage.
* NAT Gateway:Public internet access; unsuitable.
* Private Endpoint:Alternative private access, but newer feature.
* HTTPS:Ensures in-transit encryption.
* Evaluate Options:
* A:Encryption at rest doesn't cover transit; incomplete.
* B:NAT uses public internet; violates policy; incorrect.
* C:Service Gateway with HTTPS ensures full encryption and privacy; correct.
* D:Private Endpoint with HTTPS is valid but less common than Service Gateway; slightly less optimal historically.
* Conclusion:Service Gateway with HTTPS is most secure and compliant.
Service Gateway is standard for private Object Storage access. The Oracle Networking Professional study guide states, "A Service Gateway with HTTPS API calls ensures end-to-end encrypted traffic to Object Storage without public internet traversal" (OCI Networking Documentation, Section: Service Gateway). This meets security mandates effectively.

123. Frage
You are designing a multi-tier application in OCI, deploying the application tier in a public subnet and the database tier in a private subnet within the same VCN. The application tier requires access to specific external internet resources for software updates and third-party API calls. However, the database tier should not have direct internet access. Which of the following is the most secure and efficient method to achieve this configuration?

A. Configure a NAT Gateway for the private subnet and a Service Gateway for the public subnet.
B. Configure a NAT Gateway for the public subnet and a Service Gateway for the private subnet.
C. Configure a NAT Gateway for the private subnet and an Internet Gateway for the public subnet.
D. Configure a NAT Gateway for both the public and private subnets.

Antwort: C

Begründung:
* Requirements:App tier (public) needs internet; DB tier (private) must not.
* Components:
* Internet Gateway:Full internet access for public subnets.
* NAT Gateway:Outbound-only internet for private subnets.
* Service Gateway:Private OCI service access.
* Evaluate Options:
* A:Reversed roles; public subnet doesn't need Service Gateway; incorrect.
* B:NAT for public is unnecessary with Internet Gateway; inefficient.
* C:NAT for public is wrong; Service Gateway doesn't block DB internet; incorrect.
* D:Internet Gateway for app, NAT for DB if needed, aligns with policy; correct.
* Conclusion:Option D is most secure and efficient.
Subnet roles dictate gateway use. The Oracle Networking Professional study guide states, "Public subnets use an Internet Gateway for full internet access, while private subnets can use a NAT Gateway for outbound-only access, ensuring no direct internet exposure" (OCI Networking Documentation, Section: VCN Gateways).
Option D balances security and functionality.
