質問 # 24
Which OCI component facilitates transitive routing between VCNs in different regions via a dedicated, private network backbone, while also enabling connectivity to on-premises networks?

A. Internet Gateway
B. Local Peering Gateway (LPG)
C. Dynamic Routing Gateway (DRG)
D. Service Gateway

正解：C

解説：
* Requirement:Transitive routing across regions and to on-premises, privately.
* Components:
* LPG:Intra-region VCN peering; limited scope.
* DRG:Cross-region and on-premises routing via private backbone.
* Service Gateway:OCI service access; not transitive.
* Internet Gateway:Public internet; not private.
* Evaluate Options:
* A:Region-specific; incorrect.
* B:Supports multi-region and on-premises; correct.
* C:Service-focused; incorrect.
* D:Public; incorrect.
* Conclusion:DRG is the key component.
DRG enables complex routing scenarios. The Oracle Networking Professional study guide notes, "The Dynamic Routing Gateway (DRG) facilitates transitive routing between VCNs in different regions and on- premises networks over OCI's private backbone" (OCI Networking Documentation, Section: Dynamic Routing Gateway). This meets both requirements efficiently.

質問 # 25
You are working as an OCI Network Specialist. Your company is migrating its on-premises IPv6 network to OCI. As part of the migration, you need to enable communication between the on-premises network and a VCN in OCI using FastConnect. Your company utilizes global unicast IPv6 addresses on-premises and wants to continue utilizing those addresses in OCI. However, you have a restriction that compute instance traffic must be limited to IPv6 only. After assigning IPv6 addresses from the prefix to the instance, they cannot ping external IPv6 addresses. What configuration most likely addresses this issue?

A. You can't use your own IPv6 address space in OCI. You must use OCI's provided ULA.
B. Ensure that there are IPv6 default routes (::/0) pointing to a NAT Gateway in your VCN route tables.
C. Ensure that there is an Internet Gateway (IGW) attached to the VCN with a default route (::/0) in your subnet route table.
D. Ensure that there is a Service Gateway attached to the VCN with a default route (::/0) in your subnet route table.

正解：C

解説：
* Problem: Instances with IPv6-only traffic can't ping external IPv6 addresses despite FastConnect and IPv6 prefixes.
* Option A: OCI supports Bring Your Own IP (BYOIP) for IPv6, including global unicast addresses, so this is incorrect.
* Option B: NAT Gateways are for IPv4 outbound traffic, not IPv6-irrelevant here.
* Option C: For IPv6-only instances to reach external IPv6 addresses (beyond FastConnect),an Internet Gateway (IGW) is required with a default route (::/0) in the subnet route table. This enables public IPv6 connectivity-correct.
* Option D: Service Gateway is for OCI services, not general IPv6 internet access-incorrect.
* Conclusion: Option C fixes the issue by enabling IPv6 internet access.
Oracle states:
* "To enable IPv6 traffic to the internet, attach an Internet Gateway to the VCN and add a route rule for ::
/0. OCI supports BYOIP for public IPv6 prefixes."This aligns with Option C. Reference:IPv6 in OCI - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingIPv6.htm).

質問 # 26
Which OCI resource is used to establish private connectivity between two VCNs within the same region, facilitating direct, low-latency communication?

A. Internet Gateway
B. Local Peering Gateway (LPG)
C. Dynamic Routing Gateway (DRG)
D. Service Gateway

正解：B

解説：
* Objective: Identify the OCI resource for private, low-latency VCN-to-VCN connectivity in the same region.
* Option A: DRG connects VCNs to external networks (e.g., on-premises) or across regions, not for same-region peering-incorrect.
* Option B: LPG is designed for private peering of VCNs within the same region, ensuring low-latency communication-correct.
* Option C: Internet Gateway provides public internet access, not private connectivity-incorrect.
* Option D: Service Gateway connects VCNs to OCI services, not other VCNs-incorrect.
* Conclusion: Option B is the appropriate resource.
Oracle documentation states:
* "A Local Peering Gateway (LPG) enables private connectivity between two VCNs in the same region, providing direct, low-latency communication."This confirms Option B. Reference:Local VCN Peering Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/localVCNpeering.
htm).

質問 # 27
You are designing a hybrid cloud architecture connecting your on-premises network to OCI. You have established a Site-to-Site VPN between your on-premises network and an OCI DRG. You have two VCNs attached to the DRG: VCN-A (10.0.0.0/16) and VCN-B (10.1.0.0/16). You need to ensure that only VCN-A can communicate with the on-premises network (192.168.1.0/24), while VCN-B should remain isolated. What is the MOST effective and secure method to achieve this connectivity requirement using DRG route tables?

A. Create two DRG route tables: DRG-RT-A and DRG-RT-B. In DRG-RT-A, add a route rule for
192.168.1.0/24 pointing to the VPN attachment. Associate DRG-RT-A with the VCN-A attachment. In DRG-RT-B, add a route rule for 192.168.1.0/24 pointing to the VPN attachment and associate DRG- RT-B with the VCN-B attachment. Then, use security lists to block all traffic between VCN-B and the on-premises network.
B. Create two DRG route tables: DRG-RT-A and DRG-RT-B. In DRG-RT-A, add a route rule for
192.168.1.0/24 pointing to the VPN attachment. Associate DRG-RT-A with the VCN-A attachment.
Associate DRG-RT-B (containing no routes for 192.168.1.0/24) with the VCN-B attachment.
C. Create a single DRG route table. Add a route rule to the DRG route table for 192.168.1.0/24 pointing to the VPN attachment. Associate this route table with the VCN-A attachment. Associate a default DRG route table that contains no routes for the VPN attachment with the VCN-Battachment.
D. Create a single DRG route table. Add a route rule to the DRG route table for 192.168.1.0/24 pointing to the VPN attachment. Associate this route table with both the VCN-A and VCN-B attachments.
Implement Network Security Groups (NSGs) on VCN-B to block all traffic to and from 192.168.1.0/24.

正解：B

解説：
* Objective: Allow VCN-A to access on-premises (192.168.1.0/24) via VPN, isolate VCN-B using DRG route tables effectively and securely.
* Option A: Single route table for both VCNs with NSGs on VCN-B to block traffic. This works but relies on NSGs, which are secondary to routing. Routing-level isolation is more secure and efficient.
* Option B: Single route table for VCN-A with the VPN route, default table (no VPN route) for VCN-B.
This isolates VCN-B effectively at the routing level, but managing one table across all attachments can complicate scaling.
* Option C: Two route tables, both with VPN routes, then blocking VCN-B with security lists. This is inefficient-routes are advertised unnecessarily, relying on security lists instead of routing isolation.
* Option D: Two route tables-DRG-RT-A with VPN route for VCN-A, DRG-RT-B with no VPN route for VCN-B. This ensures VCN-B has no path to on-premises at the DRG level, providing the strongest isolation.
* Conclusion: Option D is the most effective and secure, leveraging routing for isolation rather than secondary security controls.
Oracle documentation states:
* "DRG route tables control traffic between VCN attachments and external connections (e.g., VPN).
Associate a unique route table with each attachment to enforce specific routing policies."
* "To isolate a VCN, ensure its DRG route table contains no routes to the destination."Option D aligns with this approach. Reference:Dynamic Routing Gateway Overview - Oracle Help Center(docs.oracle.
com/en-us/iaas/Content/Network/Tasks/managingDRGs.htm).

質問 # 28
You are designing an OCI architecture where a custom application running on a compute instance in a private subnet needs to securely access an Oracle Integration Cloud (OIC) instance. The security policy mandates that all communication remains within the OCI network and avoids traversing the public internet. Which type of endpoint provides the most secure and direct connectivity for this scenario?

A. Regional Endpoint
B. Public Endpoint
C. Service Gateway Endpoint
D. Private Endpoint

正解：D

解説：
* Requirement:Private, secure access to OIC from a private subnet.
* Endpoint Types:
* Public:Internet-based; violates policy.
* Service Gateway:For OCI services like Object Storage, not OIC.
* Private:VCN-internal access to services; fits OIC.
* Regional:Ambiguous, not specific; incorrect.
* Evaluate Options:
* A:Public internet; incorrect.
* B:Wrong service target; incorrect.
* C:Private within VCN; correct.
* D:Undefined scope; incorrect.
* Conclusion:Private Endpoint ensures secure connectivity.
Private Endpoints secure OIC access. The Oracle Networking Professional study guide notes, "A Private Endpoint allows applications in a private subnet to access Oracle Integration Cloud (OIC) within the OCI network, avoiding public internet exposure" (OCI Networking Documentation, Section: Private Endpoints).
This meets the security policy directly.
