Configuring Cloud Interconnect

Objective 4.1 sits in Configuring and implementing hybrid and multicloud network interconnectivity, which carries 16% of the Cloud Network Engineer exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

Shown solved, with the whole explanation open: this is what every question here carries.

4-1Configuring and implementing hybrid and multicloud network interconnectivity

A team orders a single 10-Gbps circuit and plans to leave link aggregation off their router. What do the colocation device requirements say about that?

Aggregation is replaced by multi-hop BGPRouting protocol support is a separate line entirely.
Aggregation applies from the second circuitNo threshold defers this to a later circuit.
Aggregation is optional at every circuit countThe list is a requirement, not a set of suggestions.
Aggregation is required even for one circuitCorrect · your answerCorrect. The requirement does not scale with circuit count.

Correct.

Concept

A physical requirement can exist for consistent configuration and later growth rather than for redundancy today, which is why it binds at the smallest deployment too.

Why D

On-premises network devices must support LACP even when only a single circuit is in use, alongside IPv4 link local addressing, EBGP-4 with multi-hop and 802.1Q VLANs.

Source

In the colocation facility, your network devices must support the following technical requirements: At least one of the following: 10-Gbps circuits, single mode fiber, 10GBASE-LR (1310 nm) 100-Gbps circuits, single mode fiber, 100GBASE-LR4 400-Gbps circuits, single mode fiber, 400GBASE-LR4 IPv4 link local addressing LACP, even if you're using a single circuit EBGP-4 with multi-hop 802.1Q VLANs
