Enterprise Network Design

A large enterprise is redesigning its campus network to support 5000 users across three buildings. The design must provide high availability and fast convergence in case of a link failure. The network engineer is considering using Spanning Tree Protocol (STP) in the access layer. What is the primary design concern with using STP in this scenario?

A company is deploying a new data center and needs to choose between a three-tier (core, aggregation, access) and a spine-leaf architecture. The network engineer is concerned about east-west traffic patterns for server virtualization. Which architecture is most suitable and why?

An enterprise network is experiencing high CPU utilization on the distribution layer switches. The design uses VLANs with SVIs for inter-VLAN routing, and HSRP for first-hop redundancy. The engineer notices that the standby switch is also experiencing high CPU. What is the most likely cause?

A network engineer is designing a WAN connection for a branch office that requires high availability and bandwidth aggregation. The branch has two internet connections from different ISPs. The engineer wants to use both links actively for load balancing and failover. Which design approach should be used?

A campus network uses a collapsed core design with two distribution switches and multiple access switches. The engineer wants to ensure that if one distribution switch fails, the access switches can still reach the core. The access switches are connected to both distribution switches. What additional configuration is required on the access switches?

An enterprise is migrating from a traditional three-tier campus design to a software-defined access (SD-Access) fabric. The engineer needs to ensure that the existing wireless infrastructure integrates seamlessly. Which component of SD-Access is responsible for integrating wireless and wired policies?

A network engineer is designing a data center network using Cisco ACI. The design must support multiple tenants with isolated policies. The engineer needs to ensure that traffic between endpoints in different tenants is blocked by default. Which ACI construct provides this isolation?

A company is deploying a new branch office with 50 users. The branch needs to connect to the headquarters via a WAN link. The engineer wants to use a design that minimizes the need for routing protocol configuration at the branch while still providing redundancy. Which design is most appropriate?

An enterprise network uses OSPF in the core and EIGRP in the campus distribution layer. The engineer needs to redistribute routes between the two protocols. Which design consideration is most important to prevent routing loops?

An architect is designing an SD-Access fabric for a campus network that must support dynamic endpoint grouping based on user identity and device type. The design must minimize manual policy configuration and allow the fabric to enforce access policies at the edge. Which combination of components and protocols is required to meet these requirements?

A network team is designing an SD-WAN overlay for a multinational enterprise with 500+ branch sites. The design must ensure that control plane traffic (e.g., OMP updates) is encrypted and authenticated between all vSmart controllers and vEdge routers, while allowing data plane traffic to use IPsec tunnels between branch sites directly. Which architectural element is responsible for orchestrating the initial authentication and certificate enrollment of all SD-WAN devices?

An enterprise is redesigning its WAN QoS architecture to support real-time voice, video, and critical data applications over a limited bandwidth link. The architect must ensure that voice traffic receives strict priority queuing and that video traffic is guaranteed a minimum bandwidth, while allowing best-effort traffic to use remaining capacity. Which queuing strategy should be deployed on the WAN edge routers?

A service provider is deploying NFV to host virtual network functions (VNFs) such as firewalls, routers, and WAN optimizers on a single server. The design must support service chaining, where traffic flows through multiple VNFs in a specific order, and must allow dynamic insertion of new VNFs without re-cabling. Which technology should be used to implement the service chain?

A data center architect is designing a virtualized environment to host critical applications. The design must maximize performance by allowing virtual machines (VMs) to directly access physical CPU cores and memory without hypervisor overhead for latency-sensitive workloads. Which hypervisor configuration should be used?

A network architect is designing a campus network for a large university with 10,000+ users. The design must provide high availability, minimize failure domains, and allow for easy scaling of the access layer. The core layer should be resilient and support fast convergence. Which hierarchical design model best meets these requirements?

An enterprise is deploying Cisco SD-WAN and must ensure that data plane traffic between branch sites is encrypted and authenticated. The design must also allow the use of application-aware routing to steer traffic based on real-time performance metrics. Which component is responsible for establishing and managing the IPsec tunnels between branch routers?

A network architect is designing QoS for a converged network carrying voice, video, and data. The design must use the DiffServ model and ensure that voice traffic is marked with the highest priority and that video traffic is marked with a lower priority but still above data. Which DSCP markings should be assigned to voice and video traffic, respectively, to comply with the standard Per-Hop Behavior (PHB) definitions?

An enterprise is migrating its data center to a leaf-spine architecture to support high east-west traffic between servers. The design must provide non-blocking forwarding and allow for easy scaling by adding more spines. Which characteristic is essential for the spine switches in this design?
