ANS-C01 Question 142
Select 3Your organization is setting up a Direct Connect connection between your on-premises data center and your AWS environment. To optimize network performance and ensure efficient data transfer, you need to configure the setup to support multiple VLANs and maximize throughput. Which of the following configurations should you implement?
- A
Enable 802.1Q VLAN tagging on the Direct Connect interface.
- B
Configure a Link Aggregation Group (LAG) to bundle multiple connections for increased bandwidth.
- C
Enable jumbo frames for the Direct Connect interface to reduce packet fragmentation.
- D
Use single-mode optics for the connection to ensure compatibility with AWS Direct Connect.
- E
Disable VLAN tagging to simplify network configuration.
Show answer and explanation
Correct answers: A, B, C
Explanation
To optimize the Direct Connect configuration for multiple VLANs and maximum throughput, you need to enable 802.1Q VLAN tagging to support multiple VLANs, configure a Link Aggregation Group (LAG) for increased bandwidth, and enable jumbo frames to reduce packet fragmentation. These configurations collectively ensure better performance and efficiency for your Direct Connect setup.
- A. Correct.
Correct: AWS Direct Connect supports 802.1Q VLAN tagging, which is required to segregate traffic for multiple VLANs. This is a standard practice in multi-VLAN setups.
- B. Correct.
Correct: A Link Aggregation Group (LAG) can be used to combine multiple connections into a single logical connection for increased bandwidth and redundancy.
- C. Correct.
Correct: Enabling jumbo frames (MTU 9001) reduces the overhead of packet headers and improves performance for large data transfers over AWS Direct Connect.
- D. Incorrect.
Incorrect: While single-mode optics may be required depending on the connection type, this is not directly related to optimizing for VLANs or maximizing throughput.
- E. Incorrect.
Incorrect: Disabling VLAN tagging would prevent you from supporting multiple VLANs, which conflicts with the scenario requirements.
