Final answer:
VIA addresses are used to route packets to their destination within a network. They are part of a routing table and guide the packet's journey to its endpoint but do not handle tasks such as assigning IP addresses, securing connections, or monitoring traffic.
Step-by-step explanation:
The action that may be taken by VIA addresses is A) Route packets to their destination. VIA is a term that can be associated with network routing. When a device in a network decides where to send a packet next, it is utilizing the routing capability, often by referencing a routing table that contains VIA addresses. VIA addresses function as instructions for the packet's journey through the network towards its ultimate destination. They do not assign IP addresses to devices (which is a function of DHCP servers), establish secure connections (which is a function of cryptographic protocols), or monitor network traffic (which is a function of network monitoring tools).
