• The city virtualization cluster runs a bare-metal hypervisor under production VMs. How does that Type 1 model differ from a Type 2 hypervisor?
• County clerk staff want a quick lab of VDI images on admin workstations using a hosted hypervisor. Which choice best fits that Type 2 use case versus production Type 1?
• Transit OCC must keep fare-collection VMs isolated from CAD VMs even though both run on the same hypervisor host. What is the primary purpose of that VM isolation?
• A police evidence VM needs connectivity to the evidence network through the host. Which component provides that Layer 2 switching function for the VM's vNIC?
• Sanitation's datacenter lab is comparing a hypervisor-hosted virtual router with a physical CPE appliance. What trade-off best reflects device virtualization at ENCOR depth?
• After vandalism, the library kiosk farm must rebuild guest images quickly from a known-good baseline. What device-virtualization benefit best explains that approach?
• Airport operations is sizing a new production hypervisor cluster and needs to know whether the hypervisor should sit on bare metal or atop a general-purpose host OS. Which statement correctly distinguishes the models?
• Courthouse lab engineers want virtual-switch VLANs that mirror production segmentation for case-management and public-Wi-Fi guests. What should they expect from virtual switching?
• A water utility must keep SCADA routing separate from guest Wi-Fi on the same edge router. Which data-path virtualization approach best meets that need?
• Parks HQ needs an IP overlay to a remote nature center across an untrusted ISP and staff propose a plain GRE tunnel. What limitation should they recognize?
• Police records must traverse a GRE path to a records annex, and confidentiality is required. Why combine IPsec with GRE rather than leaving GRE alone?
• City hall discovers finance routes appearing inside the public-kiosk VRF after a change. What does that symptom most clearly indicate about VRF design?
• Ferry terminal staff are building a simple point-to-point GRE overlay and must set tunnel endpoints correctly. What roles do the tunnel source and destination play?
• A housing authority needs site-to-site confidentiality for ordinary IP unicast between two offices and does not require GRE's multiprotocol overlay. Which approach fits?
• A municipal hospital must multi-tenant guest Wi-Fi routing away from clinical systems on shared edge routers. What is the primary VRF benefit in that design?
• A 911 PSAP backup path uses GRE across LTE, and operators need to confirm the overlay is usable. Which verification concept best matches ENCOR data-path virtualization?
• County jail needs a shared printer reachable from two VRFs and plans a carefully controlled inter-VRF route exchange. How does that differ from an accidental leak?
• The convention center DMZ must protect partner connectivity across the Internet at ENCOR depth. What is the primary purpose of IPsec tunneling in that scenario?
• A school district overlays student-info traffic with GRE and then protects that path with IPsec. How should staff describe each technology's role?
• Public works places IoT meter prefixes in a VRF that must not reach finance subnets by default. Which VRF property supports that outcome?
• An airport team exploring fabric concepts asks what problem LISP addresses with locator/ID separation. Which statement is most accurate at ENCOR depth?
• City fabric architects name the data-plane encapsulation used to carry overlay segments across an IP underlay. Which technology fills that role in common enterprise fabric designs discussed in ENCOR?
• County IT is constrained by classic VLAN's 12-bit identifier space and evaluates VXLAN for larger segmentation scale. What advantage should they cite?
• Fabric-edge discussion at the county describes map-and-encap so endpoints keep stable identities while locators change. Which LISP idea does that describe?
• Stadium multi-tenant networks are drowning in sprawling Layer 2 VLANs and evaluate VXLAN VNIs for segmentation. What contrast matters most?
• Library architects ask whether LISP is primarily a control-plane mapping system in fabric-style designs rather than the data-plane encapsulation itself. Which answer is best?
• Police HQ wants overlays that span sites across a Layer 3 underlay without stretching pure Layer 2 domains. Which network-virtualization approach matches that goal?
• A municipal datacenter lab contrasts LISP terms with classic IP routing alone. How do EID and RLOC differ conceptually?
• Port authority engineers discuss which devices encapsulate and decapsulate VXLAN traffic. What is the VTEP's role?
• Emergency management is designing a fabric-style solution and asks how LISP and VXLAN typically complement each other at ENCOR concept depth?
