1Z0-1151-25 Cheatsheet — OCI Multicloud Architect Professional (Connectivity, Federation, Data)

Last-mile 1Z0-1151-25 review: multicloud connectivity pickers, identity federation patterns, data placement/replication trade-offs, and governance/security checklists.

On this page

Use this for last‑mile review. Multicloud questions usually reduce to identity + network + data + operations.

1) Multicloud mental model

    flowchart LR
	  IDP["Identity provider"] --> OCI["OCI tenancy"]
	  IDP --> OC["Other cloud"]
	  OCI <-->|"VPN/FastConnect/partner"| OC
	  OCI <-->|"replication/sync"| DATA["Shared data"]
	  OC <-->|"replication/sync"| DATA

2) Connectivity pickers (concept-level)

RequirementPreferWhy
Fast setup / lower costVPNquickest path
Higher bandwidth / steady latencyFastConnectpredictable performance
Many networks to connecthub/spoke routing patternreduces sprawl

3) Federation and access (high-yield)

  • Use federation to reduce credential sprawl (concept-level).
  • Scope permissions tightly by compartment/project.
  • Prefer short-lived credentials where possible; audit everything.

4) Data placement rules of thumb

  • Put data near the compute that consumes it (latency + egress cost).
  • Replicate only what you must; define RPO/RTO explicitly.
  • Ensure encryption and key management responsibilities are clear across clouds.
