Oracle 1Z0-1124-25 Exam Dumps

Problem: Packet loss and degradation over OCI-Azure Interconnect.

Typical Causes: Security rules, routing, MTU mismatches.

Evaluate Options:

A: NSGs/Security Lists blocking traffic is a common issue; typical.

B: Routing misconfiguration can drop packets; typical.

C: Pricing tiers affect billing, not interconnect bandwidth; not typical.

D: MTU mismatches cause fragmentation and loss; typical.

Conclusion: Pricing tiers are unrelated to interconnect performance issues.

Interconnect performance issues stem from network configuration, not pricing. The Oracle Networking Professional study guide states, 'Troubleshooting multi-cloud interconnects involves checking security rules, routing, and MTU settings, as these directly impact traffic flow' (OCI Networking Documentation, Section: Multi-Cloud Connectivity). Pricing tiers influence resource limits, not interconnect bandwidth.

Goal: Force spoke-to-spoke traffic via a network appliance in hub-and-spoke topology.

Option A: Static routes on DRG to appliance ensure transitive routing---correct.

Option B: Service Gateway is for OCI services---incorrect.

Option C: Internet Gateway is public, not hub-and-spoke---incorrect.

Option D: LPG bypasses the appliance---incorrect.

Conclusion: Option A is necessary.

Oracle notes:

'In a hub-and-spoke topology, configure DRG route tables with static routes to the network appliance's private IP for transitive routing between spokes.'

This supports Option A. Reference: Hub-and-Spoke Topology - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/hubspoke.htm).

Requirement: IAM permission to accept cross-tenancy LPG peering.

Option A: ''Manage'' allows creating and accepting peering---correct.

Option B: ''Use'' permits using existing LPGs, not accepting requests---incorrect.

Option C: ''Inspect'' is read-only, insufficient---incorrect.

Option D: ''Read'' on virtual-network-family doesn't cover LPG management---incorrect.

Conclusion: Option A is required.

Oracle states:

'To accept a cross-tenancy peering request, the target tenancy needs 'manage local-peering-gateways' permission.'

This confirms Option A. Reference: Local VCN Peering - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/localVCNpeering.htm).

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).

Objective: Identify essential info for CPE to establish a Site-to-Site VPN with OCI.

Option A: Region and availability domain are for OCI resource placement, not CPE config---incorrect.

Option B: The DRG's public IP is the VPN endpoint, and the IKE pre-shared key authenticates the tunnel---essential and correct.

Option C: OCID and compartment ID are for OCI management, not CPE setup---incorrect.

Option D: Subnet CIDRs are for routing, configured later, not for tunnel establishment---incorrect.

Conclusion: Option B provides the critical VPN connection details.

Oracle documentation states:

'To configure your CPE for Site-to-Site VPN, you need the public IP address of the DRG (VPN headend) and the IKE pre-shared key from the OCI console.'

This confirms Option B. Reference: Setting Up IPSec VPN - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPSec.htm).
