Which QoS mechanism is most commonly used to give voice traffic priority over data traffic in a converged network?

Increasing the bandwidth of the access link to eliminate congestion

Classifying voice packets and marking them with a high-priority DSCP value

Applying encryption to voice packets to reduce delay

Using a larger MTU for voice packets to reduce overhead

Why is it important to schedule backup traffic during off-peak hours in a network design?

To reduce the number of backup servers needed

To reduce the need for encryption on backup data

To increase the security of backup data by sending it at night

To avoid congestion with business-critical traffic and ensure backups complete within the available window

What is the primary purpose of using redundant links between switches in a network design?

To provide an alternate path for traffic if a primary link or device fails

To eliminate the need for routing protocols in the network

To increase the total bandwidth available for all traffic at all times

To simplify the network topology by reducing the number of switches needed

Why is redundancy important in a network design that supports data center replication?

To simplify the routing protocol configuration

To increase the latency of replication traffic

To reduce the bandwidth needed for replication

To ensure that replication continues even if a link or device fails

Which security mechanism is most directly used to enforce access control between different network segments?

Network monitoring tools that log all traffic

Encryption of all traffic with IPsec

Access control lists (ACLs) applied on routers or firewalls

Quality of Service (QoS) marking to prioritize traffic

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 1)

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.
