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?
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.
When using Service Connector Hub to route VCN Flow Logs to Object Storage for long-term analysis, which Service Connector Hub task type is essential for ensuring the logs are correctly processed and stored?
Objective: Identify the essential Service Connector Hub task for routing Flow Logs to Object Storage.
Option A (Ingest Logs): Ingesting is for bringing external logs into OCI, but Flow Logs are already OCI-native---incorrect.
Option B (Process Logs): ''Process Logs'' isn't a specific task type in Service Connector Hub---incorrect.
Option C (Deliver Logs): Deliver Logs moves logs to a target (e.g., Object Storage), ensuring storage---correct and essential.
Option D (Transform Logs): Transforming modifies logs optionally, but delivery is required for storage---incorrect as the primary task.
Conclusion: Deliver Logs is the essential task type for this scenario.
Oracle documentation states:
'The Deliver Logs task in Service Connector Hub moves logs, such as VCN Flow Logs, to a specified destination like Object Storage for storage and analysis.'
This supports Option C. Reference: Service Connector Hub Overview - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/ServiceConnectorHub/Concepts/serviceconnectorhub.htm).
When analyzing Flow Logs for a subnet, how can you filter logs to isolate traffic that was rejected due to a specific security list rule?
Goal: Filter Flow Logs for traffic rejected by a specific security list rule.
Option A: ''action'' = ''REJECT'' identifies rejected traffic; ''securityListRule'' with rule ID pinpoints the exact rule---correct.
Option B: ''status'' and ''securityRule'' aren't standard Flow Log fields (''action'' and ''securityListRule'' are)---incorrect.
Option C: ''direction'' and ''port'' filter traffic but don't specify rejection or rule---incorrect.
Option D: ''type'' and ''rule'' aren't valid Flow Log fields---incorrect.
Conclusion: Option A is the precise filtering method.
Oracle states:
'In Flow Logs, use the 'action' field ('REJECT') and 'securityListRule' field (rule ID) to filter traffic rejected by a specific security list rule.''
This validates Option A. Reference: Flow Logs Fields - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Concepts/flowlogs.htm#fields).
You are tasked with migrating a critical, latency-sensitive application from Azure to OCI. Due to compliance requirements, all data must be encrypted in transit. Which connectivity option provides the BEST combination of security and performance for this migration?
Requirements: Low latency, high security with encryption for migration.
Option A: VPN with IPSec offers encryption but has higher latency over public internet---less optimal.
Option B: ExpressRoute and FastConnect provide a private, low-latency link; TLS adds end-to-end encryption---correct and best combination.
Option C: Data Factory with HTTPS is encrypted but slow and not real-time---incorrect.
Option D: VPN with Load Balancer SSL termination breaks end-to-end encryption---incorrect.
Conclusion: Option B balances performance and security.
Oracle notes:
'For latency-sensitive migrations, use FastConnect with ExpressRoute via colocation, enhanced by TLS for secure, high-performance data transfer.''
This supports Option B. Reference: Multicloud Connectivity - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Concepts/multicloud.htm).
A development team has deployed a three-tier application in an OCI VCN. The application consists of a public-facing web tier, an application tier, and a database tier. The team reports that the web tier instances can communicate with the application tier instances, but the application tier instances cannot connect to the database tier instances. All security lists are configured to allow all traffic within the VCN. Which OCI Networking diagnostic tool would BEST help you quickly isolate the root cause of this connectivity issue?
Problem: App tier can't reach DB tier despite open security lists.
Option A: Flow Logs show traffic details but require analysis, slowing diagnosis---less efficient.
Option B: Connection Diagnostics tests connectivity (e.g., ping, traceroute) between resources, quickly pinpointing failures---correct.
Option C: Network Firewall controls traffic, not diagnoses---incorrect.
Option D: Bastion is for access, not troubleshooting---incorrect.
Conclusion: Connection Diagnostics is the best tool for quick isolation.
Oracle states:
'Connection Diagnostics provides rapid testing of network connectivity between OCI resources, ideal for isolating issues like tier-to-tier failures.''
This validates Option B. Reference: Network Troubleshooting - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/troubleshooting.htm#connectiondiagnostics).
