Free 1Z0-1085 sample questions

1. A startup wants to stop buying physical servers and instead rent compute, storage and networking that it manages itself (OS, runtime, app). Which cloud service model BEST fits this need?

   • A. Infrastructure as a Service (IaaS)
   • B. Software as a Service (SaaS)
   • C. Platform as a Service (PaaS)
   • D. Function as a Service only
   Show answer

   Correct: A. IaaS provides raw virtualized infrastructure (compute, storage, network) while the customer manages the OS and above — exactly the described need. The trap (SaaS) is fully managed ready-to-use software like Fusion Apps where the customer manages nothing below the application; PaaS abstracts the OS/runtime too.

2. A finance team is moving from buying servers to OCI and wants to articulate the financial/operational benefits to leadership. Which TWO are genuine cloud-economics benefits? (Choose 2)

   • A. Pay-as-you-go / consumption-based pricing converting CapEx to OpEx
   • B. Elasticity — scale capacity up and down so you avoid paying for idle peak hardware year-round
   • C. Guaranteed lower cost than on-premises for every possible workload
   • D. Removing all need for any access control or security configuration
   • E. Eliminating the shared responsibility model entirely
   Show answer

   Correct: A and B. Consumption-based pricing (OpEx, no upfront CapEx) and elasticity (paying only for capacity you need when you need it) are core cloud-economics benefits. The traps are myths — cloud is not automatically cheaper for every workload, you still configure security, and the shared responsibility model still applies.

3. Under the cloud shared responsibility model on OCI, which TWO items are ALWAYS the customer's responsibility regardless of service? (Choose 2)

   • A. Configuring IAM users, groups and policies appropriately
   • B. Patching the underlying hypervisor and host firmware
   • C. Securing customer data and managing its classification/access
   • D. Physical security of the OCI data centers
   • E. Maintaining the regional network backbone hardware
   Show answer

   Correct: A and C. In every shared-responsibility split, the customer always owns their data and their identity/access configuration. Hypervisor patching, physical data-center security and the regional backbone are Oracle's responsibility — choosing those is the classic misconception that the cloud provider secures "everything" or that the customer must patch the host.

4. An online retailer sees traffic spike 10x during a flash sale and drop back afterward. Which cloud benefit lets them add capacity for the spike and release it after, without owning peak hardware year-round?

   • A. Elasticity / scalability
   • B. Vendor lock-in
   • C. Co-location
   • D. On-premises over-provisioning
   Show answer

   Correct: A. Elasticity is the ability to scale resources up and down on demand so you provision for the spike only when needed. On-prem over-provisioning is the legacy anti-pattern this replaces; co-location is just renting rack space and vendor lock-in is a risk, not a benefit.

5. A company runs some workloads in its own data center and bursts others into OCI, connecting the two networks. This arrangement is BEST described as which deployment model?

   • A. Hybrid cloud
   • B. Public cloud only
   • C. Private cloud only
   • D. Community cloud
   Show answer

   Correct: A. Combining on-premises (private) infrastructure with a public cloud and connecting them is a hybrid cloud. "Public cloud only" ignores the on-prem footprint; "private cloud only" ignores OCI; community cloud is shared among organizations with common concerns and does not match.
