Connections, Network Profiles, and Metered Behavior for A+
Short answer
A technician should identify the connection type (wired, wireless, WWAN, VPN) and understand how the public/private profile affects discovery/shared access and how metered connections limit background traffic. For example, mark a hotel Wi-Fi as Public and a home router as Private. Mark cellular/WWAN as metered by default to preserve data.
Why it appears on the exam
- Choose the correct profile setting for a described scenario (home vs coffee shop). - Identify which connection type is most likely to be metered by default and why.
Key concepts
Concept 1
Required terms
Wired: A physical Ethernet connection to the LAN, typically more stable with DHCP-assigned address. Wireless: Wi-Fi connection to an access point; may require SSID and passphrase for association. WWAN: Cellular-like wide-area network connections (3G/4G/5G) used in some laptops or mobile devices. VPN: A virtual private network that encapsulates traffic over public networks to reach private resources securely.
Example
When traveling, set unknown Wi-Fi to Public to block file/printer sharing.
Concept 2
How Connections, Network Profiles, and Metered Behavior works
A technician should identify the connection type (wired, wireless, WWAN, VPN) and understand how the public/private profile affects discovery/shared access and how metered connections limit background traffic. For example, mark a hotel Wi-Fi as Public and a home router as Private. Mark cellular/WWAN as metered by default to preserve data.
Example
On a mobile hotspot, enable metered connection to stop large updates.
Concept 3
Common confusion
Mislabeling network profiles leads to unexpected blocking of discovery or sharing. Metered connection settings can suppress automatic updates, which technicians should account for when troubleshooting missing updates.
Example
If a workstation cannot access internal resources while on VPN, check VPN status and split-tunnel routing (document only; advanced routing is outside this lesson focus).
Concept 4
