Oracle 1z0-1124-25 Dumps Questions Answers

Requirements:Encrypt FastConnect traffic with minimal bandwidth impact.

IPSec Options:

DRG VPN:Native OCI solution over FastConnect.

Firewall Appliances:Adds overhead and complexity.

Compute Instances:Resource-intensive, not scalable.

Internet VPN:Uses public internet, against requirements.

Evaluate Options:

A:DRG VPN with AES-GCM (low-overhead encryption) leverages FastConnect; optimal.

B:Firewalls with AES-256 add overhead, reducing bandwidth; less effective.

C:Compute-based VPN is inefficient and public-facing; unsuitable.

D:Public internet VPN violates privacy requirement; incorrect.

Conclusion:DRG VPN with AES-GCM is the most effective solution.

OCI supports IPSec over FastConnect via DRG. The Oracle Networking Professional study guide explains, "A Site-to-Site VPN over FastConnect using the DRG provides encrypted traffic with low-overhead algorithms like AES-GCM, maintaining high bandwidth" (OCI Networking Documentation, Section: FastConnect with VPN). This meets regulatory and performance needs efficiently.

Requirements: HA and redundancy for on-premises-to-OCI connectivity.

Option A: Single FastConnect lacks redundancy—incorrect.

Option B: Single VPN over internet has no redundancy and poor performance—incorrect.

Option C: Dual FastConnect with diverse paths ensures HA and redundancy via separate routes—correct.

Option D: Internet Gateway with public IPs isn’t dedicated or redundant—incorrect.

Conclusion: Option C is the recommended approach.

Oracle advises:

"For high availability, use dual FastConnect connections with diverse paths to eliminate single points of failure in hybrid connectivity."This supports Option C. Reference:FastConnect High Availability - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#ha).

Requirements:Isolated segments, efficient IP use, easy management.

Options Analysis:

A:Separate VCNs waste IPs, high overhead; inefficient.

B:Subnets with NSGs optimize IP use, simplify control; correct.

C:Compartments are for IAM, not network isolation; incorrect.

D:VM firewalls are complex, less secure; unsuitable.

Conclusion:Subnets with NSGs are most efficient.

Subnets and NSGs provide tenant isolation. The Oracle Networking Professional study guide states, "For multi-tenant applications, use separate private subnets within a VCN and enforce isolation with NSGs and routing rules, optimizing IP utilization and management" (OCI Networking Documentation, Section: VCN Design). This balances security and efficiency.
