How does a hierarchical network design contribute to scalability?

By allowing each layer to be scaled independently, such as adding access switches without redesigning the core

By using a single large flat network to avoid inter-layer routing

By eliminating the distribution layer to reduce the number of devices

By requiring all layers to be upgraded simultaneously to maintain consistency

What is the primary purpose of network segmentation in a secure network design?

To simplify the routing table by using a single subnet

To improve performance by reducing broadcast domains

To isolate different trust zones and limit the spread of attacks

To reduce the need for encryption by keeping traffic internal

Which application requirement is most directly affected by network latency?

The time it takes for a transaction to complete

The security of the data in transit

The total amount of data that can be transferred in a given period

The reliability of the underlying transport protocol

Why is security a critical consideration when designing a network for IoT devices?

Because IoT devices are often numerous and may have limited built-in security, making them potential entry points for attacks

Because IoT devices cannot be monitored

Because IoT devices require high bandwidth and therefore need encryption

Because IoT devices use multicast and multicast is insecure

Which network capability is essential for efficiently delivering a live video stream to multiple receivers simultaneously?

Unicast routing with high bandwidth

Domain 4Objective 1

4.1 Resilient, Scalable, and Secure Modular Network Design Based on Constraints (such as Technical, Operational, Application, and Business Constraints) to Support Applications on the IP Network (such as Voice, Video, Backups, Data Center Replication, IoT, and Storage) 400-007 Practice Questions (Page 6)

Part of the 4.0 Service Design domain, which accounts for 15% of the 400-007 exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~8–12 in this domain), expect 4–6 from this objective — we provide 36 practice questions to prepare you well beyond it.
