ExpressRoute Local
- B

- C
ExpressRoute Premium
- D
ExpressRoute Standard with an unlimited data plan
Show answer and explanation
Correct answer: C
Explanation
ExpressRoute Premium is specifically designed for customers who need to connect to multiple Azure regions across different geographies and require a higher route limit. It addresses both the global coverage and large-scale routing needs. For more details, refer to Microsoft documentation: https://learn.microsoft.com/azure/expressroute/expressroute-faq.
- A. Incorrect.
Option 1: ExpressRoute Local is intended for scenarios where connectivity is only required within a specific local region. It does not allow you to connect across multiple geo-locations, making it unsuitable for a global enterprise with a need for inter-region connectivity and large route tables.
- B. Incorrect.
Option 2: ExpressRoute Standard provides connectivity to Azure services within a specific continental region and supports up to 4,000 routes. While it covers multiple datacenters within that single region, it doesn't extend connectivity to Azure regions worldwide and may not meet the routing scale needed by a large global enterprise.
- C. Correct.
Option 3: ExpressRoute Premium extends connectivity across all Azure regions, not just within one continent, and allows more routes (up to 10,000). It� designed for customers needing to span multiple geographic locations and larger BGP route limits, which fits the requirements of a global retail enterprise.
- D. Incorrect.
Option 4: ExpressRoute Standard with an unlimited data plan removes outbound data transfer charges but still does not enable global connectivity beyond the local continent, nor does it increase the route table limit. Hence, it does not address the organization� global reach and large routing requirements.
