CompTIA Updated N10-009 Exam Questions and Answers by vihaan

For an internal network using IPv6, the best option listed is OSPFv3, which is the OSPF version designed to support IPv6 routing. In Network+ (N10-009) routing objectives, OSPF is a common interior gateway protocol (IGP) used within an organization (an autonomous system) to exchange routes dynamically and converge efficiently. OSPFv3 maintains the link-state approach of OSPF while adding IPv6 support, making it a strong fit for enterprise internal routing where multiple routers and subnets need dynamic path calculation and fast convergence.

BGP4 and iBGP are associated with BGP, primarily used for inter-domain routing on the internet and between large networks; while BGP can carry IPv6 (via MP-BGP), it is generally not the “best” default choice for a typical internal-only enterprise network unless there is a specific design reason. EIGRP can support IPv6 in some implementations, but Network+ typically emphasizes OSPF/OSPFv3 as the widely adopted, vendor-neutral IGP for IPv6 deployments. Given the options and the “best for this setup” wording, OSPFv3 is the most appropriate answer.

Troubleshooting poor performance of a newly installed access point involves multiple steps. Checking for network bottlenecks and ensuring the device firmware is up to date are crucial first steps. The document confirms:“Network bottlenecks can severely limit the performance of even the fastest wireless access points, so it’s essential to verify that no other devices are causing a slowdown. In addition, keeping firmware updated ensures optimal performance and security.”

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.
