20+ practice questions focused on Network Infrastructure and Connectivity — one of the most tested topics on the CCNA 200-301 v2 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Network Infrastructure and Connectivity PracticeWhat does a host rely on when using SLAAC to build an IPv6 address?
Explanation: With Stateless Address Autoconfiguration, hosts learn the prefix information from ICMPv6 Router Advertisements and then build their own interface identifier.
What is the primary purpose of encapsulation in networking?
Explanation: Encapsulation adds protocol headers and trailers so data can be interpreted and forwarded correctly at each layer.
Which statement best describes the purpose of an IPv6 link-local address?
Explanation: An IPv6 link-local address is meant for communication on the local network segment only. In plain language, it lets devices talk to nearby neighbors without needing a globally routable address. Routers use link-local addresses for neighbor relationships, and hosts use them for functions like Neighbor Discovery and communicating with the default gateway on the same link. These addresses are essential in IPv6 and are not just an emergency fallback. Technically, link-local addresses usually begin with the FE80::/10 prefix and are automatically created on IPv6-enabled interfaces. They are never routed beyond the local link, which is why they are different from global unicast addresses. They do not replace the concept of a default gateway; instead, hosts often use the router’s link-local address as the next-hop target on the local segment.
What is the usable host range for subnet 10.1.1.192/27?
Explanation: A /27 subnet contains 32 total addresses. In plain language, the 10.1.1.192/27 block runs from 10.1.1.192 through 10.1.1.223. The first address is the network address and the last is the broadcast address, so the usable host range is 10.1.1.193 through 10.1.1.222. This is a common subnetting question because it checks whether you can move from subnet boundary to valid host range. The key is to identify the block correctly and then exclude the reserved first and last addresses.
Which statement best describes an IPv6 link-local address?
Explanation: An IPv6 link-local address is used only on the local Layer 2 segment and is not routed beyond that link. In practical terms, it lets devices communicate with nearby neighbors even before or without having a globally routable IPv6 address. Routers use link-local addresses heavily for neighbor relationships, and hosts often use the router’s link-local address as the next hop for off-link traffic. This is a foundational IPv6 concept. The common trap is to treat link-local addresses like normal Internet-routable addresses. They are not. They are essential, but they are local-scope only.
