1z0-1124-25 Dumps with Practice Exam Questions Answers

Requirements: Low latency, high bandwidth for multicloud production.

Option A: Dedicated peering via third-party provider offers high performance—optimal.

Option B: IPSec VPNs over public internet have variable latency and limited bandwidth—least optimal.

Option C: FastConnect peering with partners ensures dedicated performance—optimal.

Option D: OCI-Azure Interconnect is fast, but VPN to AWS adds latency—less optimal than A or C but better than B.

Conclusion: Option B is the least optimal due to performance constraints.

Oracle notes:

"IPSec VPNs over public internet provide security but lack the bandwidth and latency consistency of dedicated connections like FastConnect for production workloads.”This supports Option B as least optimal.

Goal:Protect web servers from SQL injection using Network Firewall.

Firewall Features:

Stateful Inspection:Basic traffic tracking, limited exploit detection.

IDPS:Detects and prevents exploits via signatures.

URL Filtering:Blocks URLs, not payload-based attacks.

Geo-location:Blocks regions, not specific threats.

Evaluate Options:

A:Default IPS lacks SQL injection specificity; insufficient.

B:IDPS with custom signatures targets SQL injection; most suitable.

C:URL Filtering doesn’t address SQL injection payloads; incorrect.

D:Geo-location is broad, not precise; ineffective.

Conclusion:IDPS with custom rules is the best feature.

IDPS in OCI Network Firewall is designed for exploit prevention. The Oracle Networking Professional study guide explains, "The Intrusion Detection and Prevention System (IDPS) uses signatures to detect and block specific threats like SQL injection, with custom rule sets for tailored protection" (OCI Networking Documentation, Section: Network Firewall IDPS). This ensures precise defense against web exploits.

Zero Trust Principles:Require explicit, identity-based access controls at every network stage.

Evaluate OCI Services:

Internet Gateway:Enables public internet access, no identity-based control.

Service Gateway:Provides private service access, no granular routing control.

NSGs:Offer stateful, identity-based rules at the VNIC level.

DRG:Facilitates routing, not identity-based access control.

NSG Fit:NSGs allow rules based on VNIC identity, source/destination IP, and ports, aligning with Zero Trust.

Conclusion:NSGs are the best fit for granular, identity-based routing control.

NSGs are pivotal for Zero Trust in OCI. The Oracle Networking Professional study guide states, "Network Security Groups provide granular, stateful security rules that can be applied to specific VNICs, enabling identity-based access controls essential for Zero Trust architectures" (OCI Networking Documentation, Section: Network Security Groups). Unlike security lists (subnet-level), NSGs offer instance-level precision.

Objective: Improve OCI-AWS data transfer performance.

Option A: Region distance affects latency—valid.

Option B: Dedicated interconnect boosts bandwidth and stability—valid.

Option C: Compute pricing doesn’t influence inter-cloud bandwidth—invalid.

Option D: WAN optimization can enhance transfer efficiency—valid.

Conclusion: Option C is not a design consideration for performance.

Oracle notes:

"To optimize OCI-AWS connectivity, consider region proximity, dedicated interconnects, or WAN optimization. Compute pricing is unrelated to network performance."This excludes Option C. Reference:Hybrid Cloud Networking - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/hybridcloud.htm).

Objective:Efficiently propagate on-premises route updates to multiple VCNs.

DRG Capabilities:Supports route distribution to attached VCNs.

Analyze Options:

A:Manual updates are inefficient and error-prone; unsuitable.

B:Centralized DRG with route distribution automates propagation; efficient.

C:Multiple DRGs add complexity and manual effort; inefficient.

D:Service Gateway is for OCI services, not route updates; incorrect.

Conclusion:Centralized DRG with route distribution is the most efficient method.

Route distribution in a DRG simplifies multi-region routing. The Oracle Networking Professional study guide notes, "Using a centralized DRG with route distribution enabled allows routes learned from on-premises networks to be automatically propagated to all attached VCNs, reducing management overhead" (OCI Networking Documentation, Section: DRG Route Distribution). This leverages OCI’s automation capabilities.
