• A hospital needs its network test to start on the clinical application server so the first hop is that server's own interface. Where should the Enterprise Agent run?
• At a logistics hub, the application owner will not install software on the warehouse servers, but tests must still start beside those servers. What placement fits?
• A manufacturer needs a probe at the data center edge that keeps running when no engineer laptop is logged in. Which placement fits?
• A retailer wants a probe that stays beside each store firewall and keeps testing when no associate laptop is open. Which placement matches that design?
• A bank's cloud probe reaches the public gateway but cannot show the hops between the teller VLAN and the core, and the team wants that inside path from an Enterprise Agent. Which placement provides it?
• A university network team will host the probing software on a campus device that supports an Enterprise Agent. Which placement is that?
• A SaaS company runs two data centers and needs each site to originate its own path tests from inside that data center. Which design meets that need?

• At a retailer with branch stores, store laptops reach the inventory application until the VPN client connects, and then only those VPN sessions fail. Which test matches the failure?
• A university portal login completes and the page stays up, yet the live lecture audio breaks into gaps while students remain connected. Which ThousandEyes test should be built for that symptom?
• A hospital campus already collects Meraki Insight at the clinic, and nurses report that one clinical application is slow while basic connectivity stays up. Which view should the team use?
• At a bank, trading-floor laptops fail the market-data page only after a docking-station swap, while data-center Enterprise Agents stay green. Which test should be added?
• A manufacturer suspects the wireless hop on the client, because plant laptops fail the maintenance app on Wi-Fi and succeed on a docked cable. Which test should be added?
