Oracle Cloud Infrastructure 2025 Networking Professional 1z0-1124-25 Prüfungsfragen mit Lösungen (Q37-Q42):

37. Frage
Which aspect of OCI's security framework is essential for continuous monitoring and verification of packet flows, a core requirement of Zero Trust Packet Routing?

A. Static routing configurations
B. Default security lists
C. Public IP address assignments
D. Flow logs and audit trails

Antwort: D

Begründung:
* Goal: Support Zero Trust with packet flow monitoring.
* Option A: Static routing defines paths, not monitoring-incorrect.
* Option B: Security lists control access, not monitor-incorrect.
* Option C: Flow logs track traffic; audit trails log actions-essential for Zero Trust-correct.
* Option D: Public IPs enable access, not monitoring-incorrect.
* Conclusion: Option C is essential.
Oracle states:
* "Flow logs and audit trails provide continuous monitoring and verification of packet flows, critical for Zero Trust Packet Routing."This supports Option C. Reference:Zero Trust in OCI - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Concepts/zerotrust.htm).

38. Frage
You are troubleshooting a connectivity issue between two compute instances within the same VCN. Both instances are in different subnets. Instance A (IPv4: 10.0.1.10, IPv6: fc00:1:1::10) can ping its subnet gateway (10.0.1.1) and can ping the IPv6 address of Instance B (fc00:1:2::20), but cannot ping Instance B's IPv4 address (10.0.2.20). The security lists and network security groups (NSGs) are configured to allow all traffic between the subnets. The route table for Instance A's subnet has a rule to route all traffic destined to 10.0.2.0
/24 subnet to the VCN Local Peering Gateway. What is the most probable cause?

A. The route table for Instance B's subnet is missing a rule to route traffic destined for 10.0.1.0/24 to the VCN Local Peering Gateway.
B. IPv6 traffic cannot be filtered by security lists or NSGs.
C. The VCN does not have IPv6 enabled.
D. The "ping" utility is not supported on the IPv6 address.

Antwort: A

Begründung:
* Analyze Connectivity Successes:Instance A can ping its subnet gateway (10.0.1.1), indicating that local subnet routing and security rules are functioning for IPv4. It can also ping Instance B's IPv6 address (fc00:1:2::20), confirming that IPv6 routing and security rules between subnets are operational.
* Identify the Failure:Instance A cannot ping Instance B's IPv4 address (10.0.2.20). Since security lists and NSGs allow all traffic, the issue is unlikely to be a security configuration problem.
* Examine Routing for Instance A:The route table for Instance A's subnet (10.0.1.0/24) has a rule directing traffic to 10.0.2.0/24 via the VCN Local Peering Gateway (LPG). In OCI, LPGs are used for intra-region VCN peering, but here, both instances are in the same VCN, so this rule is likely a misconfiguration or irrelevant unless peering is involved. However, the successful IPv6 ping suggests basic connectivity exists.
* Check Return Path from Instance B:For a ping to succeed, Instance B must send ICMP replies back to Instance A (10.0.1.10). Instance B's subnet (10.0.2.0/24) needs a route table entry to send traffic to
10.0.1.0/24. Without this, replies are dropped, causing the IPv4 ping to fail. The IPv6 success indicates that IPv6 routing is correctly configured both ways, possibly via SLAAC or default routes.
* Evaluate Options:
* A:Incorrect. IPv6 is enabled, as Instance A pings Instance B's IPv6 address.
* B:Correct. Missing route for 10.0.1.0/24 in Instance B's subnet prevents IPv4 replies.
* C:Incorrect. Security lists and NSGs can filter IPv6 traffic in OCI.
* D:Incorrect. Ping supports IPv6, as evidenced by the successful IPv6 ping.
The most probable cause is a missing route in Instance B's subnet route table. In OCI, each subnet has its own route table, and for instances in different subnets within the same VCN to communicate, both subnets must have appropriate routes. The successful IPv6 ping suggests that IPv6 routing is intact (likely due to default behavior or SLAAC), but IPv4 requires explicit routing. Per the Oracle Networking Professional study guide,
"Route tables must be configured to direct traffic to the appropriate next hop for inter-subnet communication within a VCN" (OCI Networking Documentation, Section: Virtual Cloud Networks).

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

Antwort: B

Begründung:
* 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.

40. Frage
In a multi-region OCI environment, which configuration is necessary to allow communication between two VCNs located in different regions through a DRG?

A. Attaching each VCN to the same DRG and configuring the appropriate route tables on the DRG.
B. Attaching an LPG to each VCN and configuring route tables to peer them directly.
C. Configuring Internet Gateways on each VCN and using public IP addresses for communication.
D. Attaching a Service Gateway to each VCN and enabling transitive routing.

Antwort: A

Begründung:
* Requirement: Private communication between VCNs in different OCI regions via DRG.
* Option A: LPGs are for same-region VCN peering, not cross-region-incorrect.
* Option B: Service Gateways are for OCI service access, not VCN-to-VCN routing-incorrect.
* Option C: Attaching both VCNs to a single DRG (via Remote Peering Connections implicitly) and configuring route tables enables cross-region communication over OCI's backbone. This is the standard approach.
* Option D: Internet Gateways use public IPs, which is insecure and not private-incorrect.
* Conclusion: Option C is the necessary configuration for DRG-based cross-region connectivity.
Oracle documentation confirms:
* "To connect VCNs in different regions, attach each to a DRG using Remote Peering Connections (RPCs). Configure DRG route tables to route traffic between VCN CIDRs."Option C reflects this setup (RPCs are implied). Reference:VCN Peering Overview - Oracle Help Center(docs.oracle.com/en-us/iaas
/Content/Network/Tasks/remoteVCNpeering.htm).

41. Frage
You are responsible for managing access to an Oracle Autonomous Database (ADB) instance inyour OCI environment. You need to configure a secure connection to the ADB from compute instances located in a private subnet. You want to limit access to the ADB to only the designated compute instances. Which type of endpoint, in conjunction with appropriate security rules, provides the MOST granular control over network access to the Autonomous Database?

A. A public ADB endpoint with Network Security Groups (NSGs) restricting access.
B. A private ADB endpoint with Network Security Groups (NSGs) restricting access.
C. A Service Gateway-enabled connection with a Service Gateway configured to allow access to ADB.
D. A Dynamic Routing Gateway (DRG) connection with appropriate route rules.

Antwort: B

Begründung:
* Goal: Secure, granular access control to ADB from private subnet instances.
* Option A: Public endpoint with NSGs exposes ADB to the internet, increasing risk despite NSG restrictions-less secure than private options.
* Option B: Service Gateway provides private access to OCI services, but it's not specific to ADB instances and lacks the instance-level granularity of private endpoints.
* Option C: Private ADB endpoint assigns a private IP within the VCN, keeping traffic internal. NSGs allow precise, stateful control to specific instances, offering the most granular security.
* Option D: DRG is for external connections (e.g., on-premises), not internal VCN-to-ADB access.
* Conclusion: Option C provides the most secure and granular control.
Oracle documentation notes:
* "Private endpoints for Autonomous Database provide a private IP within your VCN, ensuring traffic stays off the public internet. Use NSGs for fine-grained access control to specific instances."This supports Option C. Reference:Autonomous Database Networking - Oracle Help Center(docs.oracle.com
/en-us/iaas/Content/Database/Tasks/adbconnecting.htm).
