Oracle 1z0-1124-25 Exam With Confidence Using Practice Dumps

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. Reference:Multicloud Connectivity Options - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/multicloud.htm#options).

Goal:Prefer FastConnect routes over public internet in OCI.

BGP Attributes:

Local Preference:Higher value prefers a path within an AS.

AS Path:Shorter path preferred, but manipulated on sender side.

Prefix Length:More specific wins, but not controllable here.

MED:Influences inbound traffic, not OCI preference.

Evaluate Options:

A:Higher Local Preference ensures FastConnect priority; correct.

B:AS Path is set by on-premises, not OCI; incorrect.

C:Prefix specificity is on-premises controlled; incorrect.

D:MED affects on-premises, not OCI; incorrect.

Conclusion:Local Preference is the right attribute.

Local Preference controls route preference in BGP. The Oracle Networking Professional study guide states, "To prioritize FastConnect routes in OCI, increase the Local Preference for routes learned via the FastConnect virtual circuit over other paths" (OCI Networking Documentation, Section: BGP Configuration). This ensures OCI prefers the private path.

Goal: Balance global load balancing with regional WAF protection near users.

Option A: Single WAF in one region creates a bottleneck and increases latency—insufficient.

Option B: GLB distributes globally to regional Load Balancers, each with a WAF, ensuringprotection close to users—correct.

Option C: WAF before GLB centralizes protection, adding latency and a single failure point—incorrect.

Option D: Source IP routing with regional WAFs is less optimal than GLB’s health-based routing—less effective.

Conclusion: Option B optimizes both goals.

Oracle states:

"OCI GLB distributes traffic across regions. Pair with regional Load Balancers and WAFs for localized protection and optimal performance."This supports Option B. Reference:Global Load Balancer Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Balance/Concepts/globalbalance.htm).
