[All Professional Cloud Network Engineer Questions]

You have provisioned a Dedicated Interconnect connection of 20 Gbps with a VLAN attachment of 10 Gbps. You recently noticed a steady increase in ingress traffic on the Interconnect connection from the on-premises data center. You need to ensure that your end users can achieve the full 20 Gbps throughput as quickly as possible. Which two methods can you use to accomplish this? (Choose two.)

A. Configure an additional VLAN attachment of 10 Gbps in another region. Configure the on-premises router to advertise routes with the same multi-exit discriminator (MED).
B. Configure an additional VLAN attachment of 10 Gbps in the same region. Configure the on-premises router to advertise routes with the same multi-exit discriminator (MED).
C. From the Google Cloud Console, modify the bandwidth of the VLAN attachment to 20 Gbps.
D. From the Google Cloud Console, request a new Dedicated Interconnect connection of 20 Gbps, and configure a VLAN attachment of 10 Gbps.
E. Configure Link Aggregation Control Protocol (LACP) on the on-premises router to use the 20-Gbps Dedicated Interconnect connection.

Dedicated Interconnects have VLAN attachments of 10Gbps. You can't have 20Gbps C is wrong!

For Dedicated Interconnect, connection capacity is delivered over one or more 10-Gbps or 100-Gbps Ethernet connections, with the following maximum capacities supported per Cloud Interconnect connection: 8 x 10-Gbps connections (80 Gbps total) 2 x 100-Gbps connections (200 Gbps total)

It's B and C. The Cloud Interconnect limit of 10 Gbps is irrelevant here because the question already tells us they have a 20 Gbps connection (meaning they must have 2 x 10 Gbps links). See here: https://cloud.google.com/network-connectivity/docs/interconnect/how-to/dedicated/creating-vlan-attachments#utilize_multiple_vlan_attachments This clearly states that you can use a 20 Gbps VLAN attachment if you have a 20 Gbps Interconnect. So you can either modify the attachment to 20 Gbps or you can configure a second one in the same region.
