Questions and Answers

What is the primary purpose of a Virtual Private Cloud (VPC) in the context of Bare Metal Servers (BMSs)?

  • To provide high bandwidth for connecting BMSs within the same availability zone
  • To enable layer-3 routing between BMSs in different availability zones
  • To support user-defined VLANs for custom network configurations
  • To logically isolate and configure a virtual network for improved security and simplified deployment (correct)

Which statement is true about the relationship between VPCs and high-speed networks?

  • High-speed networks are a subset of VPCs, providing additional bandwidth
  • High-speed networks and VPCs share the same physical plane (correct)
  • VPCs and high-speed networks are completely independent and isolated from each other
  • High-speed networks are physically separate from VPCs

What is a key limitation of high-speed networks compared to VPCs?

  • High-speed networks do not support user-defined VLANs
  • High-speed networks have lower bandwidth than VPCs
  • High-speed networks do not support layer-3 routing (correct)
  • High-speed networks are limited to a single availability zone
