ANS-C01 exam dumps: questions 401 to 500 of 512

Correct answers: A, B, D

• A. Correct.

  Amazon CloudFront is a content delivery network capable of caching and delivering content to edge locations, significantly reducing bandwidth usage and improving performance for global audiences.

• B. Correct.

  Multicast is an efficient way to deliver the same data to multiple recipients within an on-premises network, reducing bandwidth usage as compared to multiple unicast streams.

• C. Incorrect.

  Unicast streams send individual streams to every recipient, which increases bandwidth usage and does not align with the goal of reducing bandwidth consumption.

• D. Correct.

  AWS Elemental MediaLive and MediaPackage are AWS services that can encode and optimize video streams for efficient delivery, further reducing bandwidth consumption and ensuring high-quality real-time streaming.

Correct answer: A

• A. Correct.

  An AWS Site-to-Site VPN is a cost-effective solution for secure data transfer between on-premises and AWS. While it does not offer the high throughput of AWS Direct Connect, it is sufficient for consistent data transfers without requiring a dedicated line.

• B. Incorrect.

  AWS Direct Connect is designed for high-throughput, low-latency connections, but it involves significant costs for dedicated lines and is not the most cost-effective option for this use case.

• C. Incorrect.

  AWS Snowball is suited for one-time or infrequent large-scale data transfers, but it is not practical for consistent, ongoing data transfer needs.

• D. Incorrect.

  Using the internet with a public IP address is not secure and could result in high variability in performance, making it unsuitable for consistent and secure data transfer.

Correct answer: B

• A. Incorrect.

  AWS Direct Connect provides a dedicated physical connection for high-bandwidth, low-latency requirements. However, it is more expensive compared to other options, making it less suitable for cost-sensitive scenarios with moderate data transfer needs.

• B. Correct.

  AWS Site-to-Site VPN is a cost-effective option for securely connecting an on-premises environment to an Amazon VPC over the internet. It is well-suited for moderate data transfer needs and avoids the higher costs of dedicated connections like Direct Connect.

• C. Incorrect.

  AWS Transit Gateway with Direct Connect attachment is designed for large-scale and complex network architectures. It is more expensive and not necessary for moderate data transfer needs, making it a less cost-effective option in this scenario.

• D. Incorrect.

  An Internet Gateway with public IPs can be used to transfer data over the public internet, but it lacks security features such as encryption, which are often required for connectivity between on-premises environments and VPCs. This makes it unsuitable for most production use cases.

Correct answers: A, C

• A. Correct.

  AWS Direct Connect with a 1 Gbps connection provides dedicated, consistent bandwidth between on-premises and AWS. It's cost-effective for large data transfers because you avoid internet bandwidth charges and gain consistent performance.

• B. Incorrect.

  AWS Site-to-Site VPN over the internet is a viable option for secure connectivity, but it is not cost-effective for ongoing large data transfers due to potential internet bandwidth costs and inconsistent performance.

• C. Correct.

  Using AWS Snowball Edge for the initial data transfer reduces the costs and time for transferring large datasets. Combining it with Site-to-Site VPN for ongoing synchronization can be a cost-effective and efficient solution.

• D. Incorrect.

  Using an internet gateway and Elastic IPs for data transfer is not a recommended solution for large data movement due to high data transfer costs and lack of consistent performance.

• E. Incorrect.

  AWS Transit Gateway with Direct Connect Gateway is a scalable solution, but it is more suitable for complex multi-VPC and multi-region architectures rather than cost-effective direct connectivity for large data transfers.

Correct answers: B, D

• A. Incorrect.

  AWS Direct Connect is a dedicated physical connection between on-premises and AWS. While highly secure and reliable, it is not cost-effective for low data transfer needs.

• B. Correct.

  Site-to-Site VPN over the internet is a cost-effective and secure option for connecting on-premises to a VPC when data transfer requirements are relatively low.

• C. Incorrect.

  AWS PrivateLink is used to privately access services hosted on AWS without exposing them to the public internet. It is not suitable for connecting on-premises environments to a VPC.

• D. Correct.

  AWS Transit Gateway with Site-to-Site VPN can consolidate and manage multiple VPN connections cost-effectively. It is a viable and scalable option when low-cost connectivity is required for multiple VPCs and on-premises environments.

• E. Incorrect.

  VPC Peering connects two VPCs to enable communication between them. It cannot be used for connecting on-premises environments to a VPC.
