350-401 Practice Question: An architect is planning a virtualized…
An architect is planning a virtualized infrastructure for a branch office that will host a Cisco ISRv router and a local DHCP server. The architect wants to minimize management overhead and ensure the VMs can be easily backed up. Which hypervisor deployment model is most appropriate?
⚠ Common exam trap
Cisco often tests the distinction between Type 1 and Type 2 hypervisors in the context of network functions like ISRv, where the trap is that candidates may choose a Type 2 hypervisor for simplicity, overlooking the performance and management overhead penalties for production branch office deployments.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy a Type 1 hypervisor on the branch server and manage VMs via a centralized vCenter or similar tool.
A Type 1 hypervisor (bare-metal) runs directly on the server hardware, providing near-native performance for the Cisco ISRv router and DHCP server. Centralized management via vCenter or similar tools reduces administrative overhead and enables efficient VM backup and recovery, meeting the architect's requirements for minimal management overhead and easy backup.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploy a Type 1 hypervisor on the branch server and manage VMs via a centralized vCenter or similar tool.
Why this is correct
A Type 1 hypervisor runs directly on the branch server's hardware without a host OS, delivering near-native performance for production VM workloads. Centralized management via vCenter or a similar tool provides enterprise-grade features such as live migration, centralized logging, role-based access control, and snapshot-based backup—essential for managing a branch ISRv and DHCP server. This approach maintains the isolation and resource control needed for a virtual router while giving administrators a single pane of glass for the entire branch environment.
- ✗
Use a Type 2 hypervisor on a desktop PC at the branch.
Why it's wrong here
A Type 2 hypervisor, such as VirtualBox or VMware Workstation, runs as an application on top of a desktop operating system, competing with other processes for CPU, memory, and I/O. This introduces additional latency and reduces stability, making it unsuitable for hosting production network functions like a Cisco ISRv that require predictable throughput and high availability. Furthermore, a desktop PC lacks the server-grade components (redundant power, ECC memory, remote management) and the centralized enterprise management capabilities that are mandatory for branch network infrastructure.
- ✗
Run the ISRv and DHCP server as containers on the same host.
Why it's wrong here
Containers share the host OS kernel and lack a full guest operating system, so they cannot run a Cisco ISRv router, which requires its own dedicated kernel and hypervisor-level isolation to support network functions like routing protocols. This option is tempting because containerisation reduces overhead and simplifies deployment for stateless applications, and would be correct if the scenario involved lightweight microservices rather than a virtual router needing full OS resources.
- ✗
Install the ISRv directly on physical hardware without virtualization.
Why it's wrong here
Cisco ISRv is distributed as a virtual appliance or disk image that expects to run under a hypervisor; it does not install as a standalone OS on bare-metal hardware like a traditional physical router. Installing it directly on physical hardware would be unsupported and would also forfeit the core reasons for virtualization in the first place—snapshots for rollback, cloning for rapid provisioning, resource overcommit, and encrypted VM backups. A physical installation would tie the ISRv to one machine, eliminating the flexibility to migrate or restore the router after hardware failure without reconfiguration.
