1Z0-997-25 exam dumps: questions 101 to 175 of 175

Correct answer: A

• A. Correct.

  Correct. Setting up the OCI�Microsoft Azure Interconnect in a supported region pairing is Oracle� recommended practice for minimizing latency in a multi-cloud architecture. FastConnect and ExpressRoute seamlessly integrate through direct private peering, avoiding public internet paths and reducing latency.

• B. Incorrect.

  Incorrect. While an IPsec VPN can establish connectivity, it typically introduces higher latency and is not the preferred solution for production workloads where low latency and high throughput are critical.

• C. Incorrect.

  Incorrect. Routing traffic over the public internet�even with a NAT gateway�does not guarantee minimal latency or consistent performance and goes against typical best practices for enterprise-grade multi-cloud connectivity.

• D. Incorrect.

  Incorrect. Using third-party VPN appliances to traverse the public internet still adds unpredictability and higher latency compared to direct private peering and interconnects explicitly designed for multi-cloud setups.

Correct answer: B

• A. Incorrect.

  Option 1 is incorrect because manually replicating accounts into each cloud environment is cumbersome and prone to synchronization errors. It increases administrative overhead and does not provide a seamless single sign-on experience.

• B. Correct.

  Option 2 is correct. Federating on-premises AD with IDCS and Azure AD provides a single identity authority, automated provisioning, and consistent access controls across on-premises and both cloud environments. This approach significantly simplifies administration and enhances security.

• C. Incorrect.

  Option 3 is incorrect because deploying separate domain controllers adds complexity, requires more infrastructure management, and does not inherently provide a unified single sign-on solution across OCI, Azure, and on-premises AD.

• D. Incorrect.

  Option 4 is incorrect because relying solely on password synchronization scripts is less secure, requires constant maintenance, and fails to provide the robust federation or automated provisioning needed for enterprise-scale identity management.

Correct answer: B

• A. Incorrect.

  Incorrect. While site-to-site VPNs can offer secure tunnels, relying on the public internet for cross-cloud interactions introduces potential latency and reliability issues. This setup also does not minimize data egress costs since traffic would traverse the public internet.

• B. Correct.

  Correct. Retaining ExpressRoute to Azure and adding OCI FastConnect gives dedicated paths to each cloud. The Azure�OCI Interconnect then provides low-latency, private cross-cloud connectivity. This approach optimizes routing, reduces egress charges, and avoids performance bottlenecks.

• C. Incorrect.

  Incorrect. Solely using ExpressRoute and routing OCI traffic through the public internet adds latency and can incur higher data transfer costs. You lose the benefits of a direct connection to OCI, risking a single point of failure and increased egress fees.

• D. Incorrect.

  Incorrect. Terminating ExpressRoute in favor of FastConnect alone forces Azure traffic over VPN-based tunnels, which diminishes performance and reliability. Eliminating ExpressRoute also means losing a direct, potentially lower-cost path to Azure.

Correct answer: B

• A. Incorrect.

  Option 1 (Incorrect): A site-to-site VPN tunnel over the public Internet may be simpler short term, but it often introduces higher latency and potential bottlenecks. This approach may also raise compliance concerns given that traffic traverses the public Internet.

• B. Correct.

  Option 2 (Correct): This option meets the real-time and compliance needs by using FastConnect for a private, dedicated link from on-premises to OCI, eliminating common latency issues of the public Internet. The Oracle-Azure Interconnect provides a direct, high-bandwidth, low-latency path between Oracle Cloud and Azure, enabling hybrid and multicloud workloads.

• C. Incorrect.

  Option 3 (Incorrect): Running everything in OCI and calling Azure services over the public Internet could solve some management complexity but would not address stringent latency or compliance requirements. Public endpoints can introduce latency and potential security exposure.

• D. Incorrect.

  Option 4 (Incorrect): While HPC clusters in OCI can handle computationally intensive tasks, relying on public Internet for data synchronization to Azure does not align with strict latency or security requirements, making it less suitable for real-time or highly sensitive data scenarios.

Correct answer: B

• A. Incorrect.

  Option 1 is incorrect. While IPSec VPN is straightforward to set up, it relies on the public internet for cross-cloud traffic. This can introduce higher latency, potential bandwidth constraints, and may not reduce egress costs effectively.

• B. Correct.

  Option 2 is correct. Using OCI FastConnect for Oracle Cloud and AWS Direct Connect for AWS, then peering them in a co-located facility, provides dedicated, private, high-bandwidth connections. This approach minimizes latency, offers predictable performance, and helps optimize egress costs by avoiding public internet routing.

• C. Incorrect.

  Option 3 is incorrect. Oracle Cloud Interconnect with Microsoft Azure does not provide a direct network path to AWS. It is a dedicated integration between OCI and Azure, so it would not fulfill the requirement to connect AWS, OCI, and on-premises in a single, cohesive network layer.

• D. Incorrect.

  Option 4 is incorrect. Although NAT Gateways can facilitate secure outbound connections, depending on them for cross-cloud traffic over the public internet does not ensure low latency or guaranteed bandwidth and does not address egress cost optimization.
