A double colon in an IPv6 address indicates that a section of consecutive zeros has been compressed to shorten the address.

True

Globally-routable IPv6 addresses are designated for Internet-wide communication and serve a similar purpose to public IPv4 addresses. In IPv6, it is possible to identify a globally-routable (also known as a global unicast) address by examining the first 16 bits (or the first 4 hexadecimal digits) of the address. If an IPv6 address starts with a value between 2000 and 3FFF (or simply with a 2 or 3 as the first digit), it indicates that this address is a globally-routable IPv6 address.

True

Zero Trust Architecture (ZTA) is a security framework that eliminates implicit trust from networks. In ZTA, access decisions are made based on a combination of policies that consider factors like user identity, device health, and location (policy-based authentication). Additionally, in ZTA users and devices are continuously verified before being granted access to resources, based on real-time assessment of risk and behavior (authorization). To further enhance security, ZTA enforces the principle of giving users and devices only the minimum level of access required for their tasks, thereby reducing the attack surface (least privilege access).

True

packets within IPv4 headers, allowing IPv6 traffic to traverse IPv4 networks?

Tunneling
