GCP PCA · Question 16 · Network, Storage, Compute

CASE STUDY: MediSecure
Overview: Telehealth provider, 1500 employees, $300M revenue. Core app on AWS, 3 acquired clinics on VMware, fragmented EHRs, Active Directory.
Business Req: Unify patient records, integrate clinics in 90 days, launch patient portal.
Execs: CEO wants rapid integration; CFO wants CapEx to OpEx; CISO demands strict HIPAA/GDPR compliance.
Tech Req: End-to-end PHI encryption, comprehensive audit logging, hybrid connectivity to clinics, DR (RPO 5m, RTO 1h).
Constraints: Clinics have low bandwidth, high staff turnover requires automated IAM, legacy EHRs cannot be modified immediately.

QUESTION:
To meet the 90-day integration timeline and address the low bandwidth at the clinics, how should you establish hybrid connectivity to GCP?

Answer options:

A.

Order Dedicated Interconnect connections for each clinic.

B.

Implement HA VPN over the internet to connect the clinics to a GCP Shared VPC.

C.

Use Carrier Peering to connect the clinics directly to Google's edge.

D.

Deploy Anthos on bare metal at each clinic to process data locally.

How to approach this question

Balance the need for secure connectivity with the strict 90-day timeline.

Full Answer

B.Implement HA VPN over the internet to connect the clinics to a GCP Shared VPC.✓ Correct
While Interconnect provides higher bandwidth, it requires physical provisioning that often takes 3-6 months. HA VPN can be established immediately over the clinics' existing internet connections, meeting the strict 90-day integration deadline while providing encrypted (IPsec) connectivity.

Common mistakes

Choosing Dedicated Interconnect (A) for performance, ignoring the physical provisioning lead time.
