CompTIA Network+ N10-009 Exam Questions and Answers PDF

The MPO (Multi-fiber Push On) connector is designed to handle multiple fiber strands in a single connector, and it is commonly used with high-density transceivers like QSFP (Quad Small Form-factor Pluggable).

QSFP can support up to four channels (hence " quad " ), and MPO connectors can interface multiple fibers (e.g., 8, 12, 24), making them ideal for 40Gbps or 100Gbps deployments.

RJ45 (A) is used for Ethernet over copper.

ST (B) and LC (C) are single-fiber connectors — they don ' t support the multi-fiber needs of QSFP setups.

✅ Therefore, MPO is the correct connector type for this use case.

A hybrid cloud deployment model is the best choice for the CTO ' s requirements. It allows the organization to run key services from the on-site data center while leveraging the cloud for enterprise services. This approach provides flexibility, scalability, and cost savings, while also minimizing disruptions to users by keeping critical services local. The hybrid model integrates both private and public cloud environments, offering the benefits of both.References: CompTIA Network+ study materials and cloud computing principles.

The best answer is B. Elasticity . Quantum computing workloads are highly specialized and often require access to extremely expensive, limited, and on-demand processing resources. In cloud terms, elasticity is the ability to rapidly allocate and release resources as demand changes. That makes it a strong fit for environments where usage may spike for short periods and then drop off again.

A quantum host would not usually be designed around ordinary shared-office priorities. Instead, it would favor the ability to obtain powerful compute capacity exactly when needed, without keeping that level of capacity permanently assigned. That is the practical value of elasticity in a cloud model.

Scalability is close, but it usually describes the broader ability to increase capacity over time or as demand grows. Elasticity is more specific to dynamic, responsive adjustment of resources, which matches specialized compute workloads much better. Multitenancy refers to multiple customers sharing underlying infrastructure, and cost is always important, but neither is the main technical characteristic being highlighted here.

For exam purposes, when a scenario describes advanced or highly variable compute demand in the cloud, elasticity is usually the strongest answer because it focuses on rapid resource expansion and reduction as needed.
