Topic: Google Cloud Network Engineer topic 1 question 151

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.

B & C; You can modify a VLAN attachment for capacity to 20 Gbps or create a new one for 10 Gbps

Re: Google Cloud Network Engineer topic 1 question 151

Dedicated Interconnects have VLAN attachments of 10Gbps. You can't have 20Gbps

C is wrong!

Re: Google Cloud Network Engineer topic 1 question 151

looks like true

Re: Google Cloud Network Engineer topic 1 question 151

can only be C and E

Re: Google Cloud Network Engineer topic 1 question 151

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)

Re: Google Cloud Network Engineer topic 1 question 151

B,C is correct

each VLAN is 10Gbps max... C is wrong!

Re: Google Cloud Network Engineer topic 1 question 151

Seams that E is not a good answer because even we have only 10Gb only we configure LACP. In our case we are already in LACP. I go with B&C

Re: Google Cloud Network Engineer topic 1 question 151

can only be B & C

Re: Google Cloud Network Engineer topic 1 question 151

agree with B&C as well
