Which three disadvantages of connecting an on-premises private cloud to a colocation facility versus a cloud VPN are true? (Choose three)

The correct answer is B. QoS E. latency F. throughput. Cloud VPNs route traffic over the public internet, which inherently lacks the QoS enforcement, consistent latency, and dedicated throughput that a direct colocation facility connection provides.

Why each option

Cloud VPNs route traffic over the public internet, which inherently lacks the QoS enforcement, consistent latency, and dedicated throughput that a direct colocation facility connection provides.

Alocation availability

Location availability is not a disadvantage of cloud VPN - cloud providers offer globally distributed points of presence that often surpass the geographic reach of physical colocation facilities.

BQoSCorrect

QoS markings and policies cannot be enforced end-to-end across the public internet that cloud VPNs traverse, whereas dedicated colocation cross-connects allow consistent QoS treatment across private circuits.

Cflexibility

Flexibility is not a disadvantage of cloud VPN - cloud VPNs can be provisioned, scaled, and decommissioned entirely through software, making them more flexible than physical colocation buildouts.

Dtime to provision

Time to provision is not a disadvantage of cloud VPN - VPN tunnels can be configured in minutes, whereas establishing a colocation cross-connect requires physical installation that can take weeks.

ElatencyCorrect

Internet routing introduces higher and variable latency due to shared infrastructure and unpredictable path selection, compared to the deterministic low-latency paths of dedicated colocation circuits.

FthroughputCorrect

Cloud VPN throughput is constrained by shared internet bandwidth and congestion, while colocation connections offer dedicated, guaranteed bandwidth with predictable performance.
