Datadog Fundamentals free question 6 / 10 · Domain 3: Networking & Agent Configuration
Which domains in the installation list let hosts fetch Linux packages?
- app.datadoghq.com, the web application
- windows-agent.datadoghq.com, for the Windows installer
- yum.datadoghq.com and apt.datadoghq.com
- trace.agent.datadoghq.com, for APM payloads
Show the answer and explanation
Answer: C
Why this is correct
The Installation section lists install.datadoghq.com, yum.datadoghq.com, keys.datadoghq.com, apt.datadoghq.com, and windows-agent.datadoghq.com as the domains to add to your inclusion list to allow Agent installation. yum and apt are the package repositories used by Linux package managers.
Why the other options are wrong
"windows-agent.datadoghq.com, for the Windows installer" … windows-agent.datadoghq.com is the domain for the Windows Agent installer, not for Linux packages.
"trace.agent.datadoghq.com, for APM payloads" … trace.agent.datadoghq.com is where APM payloads are sent once the Agent is running. It is not an installation domain.
"app.datadoghq.com, the web application" … app.datadoghq.com is the URL of the US1 site web application, not an installation domain.
Key point
keys.datadoghq.com is also on the list. Keep two lists in mind: the domains needed to install the Agent, and the destinations the running Agent sends data to.
