NEW QUESTION # 30
You are designing a highly available web application in OCI. You've created a VCN with two public subnets across different Availability Domains (ADs). You need to enable IPv6 support for the application to cater to a growing number of IPv6-only clients. You plan to use a Load Balancer to distribute traffic to backend compute instances in the public subnets. Which of the following approaches ensures the highest level of resilience and IPv6 connectivity for your application?
- A. Configure the VCN with a /48 IPv6 ULA prefix. Configure the Load Balancer to listen on both IPv4 and IPv6 addresses. Ensure the backend compute instances also listen on both IPv4 and IPv6 addresses.
Route traffic accordingly using NSGs. - B. Configure the VCN with a public IPv6 CIDR block obtained from Oracle. Configure the Load Balancer to listen on IPv4 only, while backend compute instances listen on both IPv4 and IPv6, relying on NAT for IPv6 clients.
- C. Configure the VCN with a public IPv6 CIDR block obtained from Oracle. Configure the Load Balancer to listen on both IPv4 and IPv6 addresses. Ensure the backend compute instances also listen on both IPv4 and IPv6 addresses.
- D. Configure the VCN with a /48 IPv6 ULA prefix. Configure the Load Balancer to listen on IPv4 only, and the compute instances to listen on both IPv4 and IPv6, relying on NAT for IPv6 clients.
Answer: C
NEW QUESTION # 31
You are configuring a VCN with multiple subnets for a customer. The security team requires that all instances have IPv6 addresses. You configure the VCN with an IPv6 ULA CIDR block of fc00:1:1::/48 and create two private subnets. After launching instances in the two private subnets, you notice that they only have IPv4 addresses assigned. You have not manually configured any IPv6 addresses on the instances themselves. What steps are necessary to ensure the instances automatically receive IPv6 addresses?
- A. Ensure that SLAAC (Stateless Address Autoconfiguration) is enabled on the operating system of the instances within the two subnets.
- B. IPv6 address assignment is only supported on instances launched in public subnets.
- C. Make sure the "Assign public IPv4 address" option is not selected during instance creation. This will force the instance to default to IPv6 allocation.
- D. No further steps are needed. Instances will automatically receive IPv6 addresses within the configured subnets upon launch.
Answer: A
Explanation:
* Problem:Instances lack IPv6 addresses despite VCN IPv6 configuration.
* OCI IPv6 Behavior:IPv6 requires subnet enablement and OS support via SLAAC.
* Evaluate Options:
* A:Incorrect. OCI doesn't auto-assign IPv6 without OS configuration.
* B:Correct. SLAAC must be enabled on the instance OS for auto-assignment.
* C:Incorrect. IPv6 works in both public and private subnets.
* D:Incorrect. IPv4 and IPv6 assignments are independent.
* Conclusion:Enabling SLAAC on the OS ensures automatic IPv6 assignment.
IPv6 in OCI relies on SLAAC for automatic address assignment. The Oracle Networking Professional study guide states, "To enable IPv6 on instances, the VCN and subnet must have IPv6 CIDR blocks, and the instance OS must support SLAAC to automatically configure IPv6 addresses" (OCI Networking Documentation, Section: IPv6 Configuration). Without SLAAC, instances default to IPv4 only.
NEW QUESTION # 32

* Conclusion: Option D meets all criteria.
Oracle states:
* "FastConnect with DRG provides secure, low-latency hybrid connectivity. Add a Site-to-Site VPN for redundancy to ensure reliability."This supports Option D. Reference:Hybrid Cloud Connectivity - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/hybridcloud.htm).
NEW QUESTION # 48
When migrating workloads to OCI requiring consistent, high-bandwidth connections with minimal latency, and your on-premises data center has direct fiber connectivity, which OCI service is most suitable?
- A. FastConnect Colocation with Oracle
- B. Dynamic Routing Gateway (DRG) with remote peering
- C. Site-to-Site VPN
- D. Internet Gateway
Answer: A
Explanation:
* Requirements: High bandwidth, low latency, leveraging direct fiber connectivity.
* Option A: Site-to-Site VPN uses the public internet, lacking consistency and bandwidth-incorrect.
* Option B: Internet Gateway is for public access, not dedicated connections-incorrect.
* Option C: FastConnect Colocation uses direct fiber at Oracle locations, ensuring high bandwidth and minimal latency-correct.
* Option D: DRG with remote peering is for VCN-to-VCN connectivity, not optimized for on-premises fiber-incorrect (DRG is part of FastConnect but not the service itself).
* Conclusion: FastConnect Colocation is the most suitable.
Oracle states:
* "FastConnect Colocation with Oracle leverages direct fiber connections at Oracle facilities, providing consistent, high-bandwidth, and low-latency access to OCI."This supports Option C. Reference:

NEW QUESTION # 49
In the context of OCI's Zero Trust Packet Routing, which principle emphasizes the necessity of explicitly defining and enforcing access controls at every stage of network communication?
- A. Network Segmentation
- B. Perimeter Security
- C. Least Privilege
- D. Implicit Trust
Answer: C
Explanation:
* Zero Trust Context:Assumes no inherent trust, requiring explicit controls at all network stages.
* Evaluate Principles:
* Implicit Trust:Assumes trust, opposite of Zero Trust; incorrect.
* Least Privilege:Grants minimal access, explicitly enforced; aligns with Zero Trust.
* Perimeter Security:Relies on boundary protection, not Zero Trust; incorrect.
* Network Segmentation:Isolates networks, a tactic not a principle; incomplete.
* Conclusion:Least Privilege is the core principle for explicit access control.
Zero Trust Packet Routing in OCI emphasizes Least Privilege. The Oracle Networking Professional study guide states, "The Least Privilege principle in Zero Trust requires that access controls be explicitly defined and enforced at every network communication stage, ensuring no implicit trust" (OCI Networking Documentation, Section: Zero Trust Networking). This drives granular security policies.
