A network administrator needs to provide separate routing tables for a guest network and a corporate network on the same router. The guest network must only have internet access, while the corporate network can reach internal resources. What should be configured?

Create two VRFs, one for guest and one for corporate, with appropriate route leaking to the internet.

Use policy-based routing to send guest traffic to the internet.

Create two VLANs and enable inter-VLAN routing.

Use a single routing table with ACLs to block guest access to internal resources.

A small startup runs a single Linux web server on bare metal. They want to deploy two isolated web applications with different OS-level dependencies (one needs a specific kernel module, the other does not) while minimizing management overhead and maximizing resource efficiency. Which approach best meets these requirements?

Install a Type 1 hypervisor and run two VMs, one per application.

Install Docker and run two containers on the same host kernel.

Run both applications directly on the host using separate user accounts.

Use a Type 1 hypervisor for the application with the kernel module and a container for the other application.

In a service provider network, a router uses VRFs to separate customer networks. What does this provide?

Automatic encryption of customer traffic between sites.

A single shared routing table with access control lists to filter customer traffic.

Independent routing tables for each customer, so their routes do not overlap or interfere.

Layer 2 isolation between customers using VLANs.

A development team wants to test an application in an environment that closely matches production. Production uses a custom Linux kernel with specific drivers. The team needs to replicate this environment on a laptop for development. Which approach is most appropriate?

Use a container with the application only.

Use a Type 2 hypervisor to run containers.

Use a container with the custom kernel modules.

Use a VM with the custom kernel.

A network engineer is designing a multi-tenant environment on a single router. Each tenant has overlapping IP address spaces. The engineer must ensure that traffic from different tenants is isolated at Layer 3, even though they share the same physical router. Which feature should be used?

Configure VLANs and use a single routing table.

Use NAT to translate overlapping addresses into unique ranges.

Deploy VRFs, one per tenant, to maintain separate routing tables.

Implement policy-based routing to forward each tenant's traffic differently.
