質問 # 91
When applying Zero Trust principles to packet routing within OCI, what is the significance of using private endpoints instead of Service Gateways for accessing OCI services?

A. Private endpoints are only used for internet access.
B. Private endpoints automatically open all ports for service access.
C. Private endpoints restrict access to specific instances of a service, enhancing security.
D. Private endpoints eliminate the need for IAM policies.

正解：C

解説：
* Context: Zero Trust requires strict access control.
* Option A: IAM policies are still required-incorrect.
* Option B: Private endpoints limit access to specific service instances, aligning with Zero Trust- correct.
* Option C: Ports are controlled by NSGs/security lists-incorrect.
* Option D: Private endpoints are for private access, not internet-incorrect.
* Conclusion: Option B enhances security.
Oracle states:
* "Private endpoints restrict access to specific OCI service instances, enhancing Zero Trust by limiting exposure compared to Service Gateways."This supports Option B. Reference:Private Endpoints - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/privateendpoints.htm).

質問 # 92
You are deploying a three-tier web application using Infrastructure as Code (IaC) and Oracle Kubernetes Engine (OKE) within a single VCN. The application consists of a public-facing web tier (running in OKE), an application tier, and a database tier. You want to ensure that only the web tier can access the application tier, and only the application tier can access the database tier. You are leveraging Network Security Groups (NSGs) for granular access control. Your IaC code successfully creates all the components, but you are experiencing connectivity issues. Specifically, Pods in the web tier cannot reach the application tier.
Reviewing your IaC configuration, you realize the NSG assignments for the OKE cluster's node pool are misconfigured. Which of the following NSG configuration errors would most likely cause this connectivity issue?

A. The NSG associated with the OKE node pool (web tier) only allows egress traffic to the internet and does not have a rule permitting egress traffic to the application tier's NSG on the required port (8080).
B. The NSG associated with the OKE node pool (web tier) is missing an ingress rule allowing traffic from the VCN CIDR on port 443. This is causing a routing problem within the VCN.
C. The NSG associated with the OKE node pool (web tier) allows ingress traffic from 0.0.0.0/0 on port 80, but egress traffic to the application tier's NSG is missing a rule allowing TCP traffic on port 8080 (the port the application tier is listening on).
D. The NSG associated with the application tier allows ingress traffic from the VCN CIDR, but the NSG associated with the OKE node pool (web tier) has no ingress rules at all. Therefore, the OKE nodes are not reachable.

正解：A

解説：
* Problem:OKE web tier pods cannot reach the application tier.
* Traffic Flow:Web tier (OKE) initiates outbound (egress) traffic to application tier (port 8080).
* NSG Role:Controls traffic at VNIC level; must allow egress from OKE and ingress to app tier.
* Evaluate Options:
* A:Missing egress rule on OKE NSG blocks traffic; plausible but incomplete context.
* B:Ingress on OKE NSG affects incoming traffic, not outbound to app tier; incorrect.
* C:No ingress on OKE NSG doesn't block egress to app tier; incorrect.
* D:Egress limited to internet blocks app tier access (port 8080); most likely.
* Conclusion:Missing egress rule to app tier NSG is the primary issue.
NSGs require explicit egress rules for outbound traffic. The Oracle Networking Professional study guide notes, "For OKE pods to communicate with other tiers, the node pool's NSG must include egress rules to the destination NSG or CIDR on the required ports" (OCI Networking Documentation, Section: Network Security Groups with OKE). Option D reflects a common misconfiguration in IaC setups.

質問 # 93
In a multi-tier architecture with multiple application instances across different private subnets, which Bastion service approach minimizes the need for continuous maintenance of individual session configurations?

A. Deploying separate Bastion hosts in each private subnet.
B. Using dynamic port forwarding with SOCKS5 sessions allowing users to define their own targets.
C. Creating individual Bastion sessions for each application instance.
D. Implementing a centralized Bastion service with managed sessions and predefined target resource configurations.

正解：D

解説：
* Goal:Minimize maintenance of Bastion session configurations.
* Bastion Options:
* Individual Sessions:High maintenance per instance.
* Dynamic Port Forwarding:Flexible but user-managed, prone to errors.
* Centralized Service:Predefined targets, low maintenance.
* Separate Hosts:Increases complexity and overhead.
* Evaluate Options:
* A:Per-instance sessions require constant updates; inefficient.
* B:SOCKS5 shifts burden to users; moderate maintenance.
* C:Centralized with managed sessions reduces effort; optimal.
* D:Multiple hosts multiply management tasks; worst option.
* Conclusion:Centralized Bastion with managed sessions is most efficient.
OCI Bastion service supports centralized management. The Oracle Networking Professional study guide notes, "A centralized Bastion service with managed sessions and predefined target configurations minimizes administrative overhead by streamlining access to private subnet resources" (OCI Networking Documentation, Section: Bastion Service). This approach leverages OCI's automation capabilities.

質問 # 94
Your company uses OCI Certificates to manage SSL/TLS certificates for its public-facing applications. You need to implement a solution that automatically renews these certificates before they expire to avoid service disruptions. Which OCI Certificates feature or configuration best achieves this?

A. Enable "Automatic Renewal" option within the OCI Certificates service and ensure DNS validation is properly configured.
B. Manually renew the certificates through the OCI Console before their expiration date.
C. Use OCI Vault to store the certificates and manually renew them using the Vault API.
D. There is no automatic renewal feature in OCI Certificates; manual renewal is always required.

正解：A

解説：
* Goal:Automate certificate renewal in OCI Certificates.
* Feature Check:OCI Certificates supports automatic renewal.
* Evaluate Options:
* A:Manual renewal risks disruption; inefficient.
* B:Automatic Renewal with DNS validation automates process; best fit.
* C:Vault stores secrets, no renewal automation; incorrect.
* D:False; OCI Certificates has auto-renewal; incorrect.
* Conclusion:Automatic Renewal is the optimal feature.
OCI Certificates offers automated renewal. The Oracle Networking Professional study guide states, "Enable the 'Automatic Renewal' option in OCI Certificates and configure DNS validation to ensure certificates are renewed before expiration, preventing disruptions" (OCI Networking Documentation, Section: OCI Certificates). This leverages OCI's built-in automation.

質問 # 95
You are designing a hybrid cloud solution where sensitive data must be transferred between your on-premises data center and an OCI VCN. You require a dedicated, private connection with guaranteed bandwidth and low latency. In addition to FastConnect, what additional product would you implement to achieve encryption of the traffic traversing the FastConnect link and to ensure data confidentiality?

A. OCI Bastion
B. IPSec VPN
C. Oracle Cloud Infrastructure Vault
D. MACsec

正解：D

解説：
* Requirement Analysis: The solution needs a private, high-bandwidth, low-latency connection (provided by FastConnect) with encryption for data confidentiality.
* Option A (IPSec VPN): IPSec encrypts traffic at Layer 3 over public or private networks. While feasible over FastConnect, it's redundant since FastConnect is already private, adding unnecessary overhead and complexity.
* Option B (OCI Vault): Vault manages encryption keys and secrets but doesn't encrypt traffic itself- only supports application-level encryption, not link-level-incorrect.
* Option C (MACsec): MACsec (Media Access Control Security) provides Layer 2 encryption for Ethernet traffic, ideal for securing FastConnect's dedicated link directly between devices, ensuring confidentiality without higher-layer overhead-correct.
* Option D (OCI Bastion): Bastion secures remote access to VCN resources, not link encryption- incorrect.
* Conclusion: MACsec enhances FastConnect with efficient, link-level encryption, meeting all requirements.
Oracle documentation states:
* "MACsec provides Layer 2 encryption for FastConnect, securing Ethernet traffic between on-premises and OCI infrastructure. It's ideal for ensuring confidentiality over dedicated connections."This supports Option C as the best additional product. Reference:FastConnect Security Options - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#security).
