If a service VLAN has set the VLAN Pool to a dual-stack address pool, STA will successfully obtain an IPv4 address and an IPv6 address.

Question

Options

• ATRUE
• BFALSE

• A
  26% (7)
• B
  74% (20)

Explanation

Option B is correct because configuring a dual-stack address pool on a service VLAN is a necessary but not sufficient condition - the STA will only obtain an IPv4 address from such a configuration, not both an IPv4 and IPv6 address simultaneously. In most implementations (e.g., Huawei campus/WLAN platforms), a dual-stack address pool tied to a service VLAN does not automatically trigger DHCPv6 or SLAAC assignment to the STA; additional IPv6-specific configurations (such as enabling RA or DHCPv6 service) are required for the STA to also acquire an IPv6 address. Option A is wrong because it assumes pool type alone determines what the client receives, ignoring the protocol-level mechanisms (DHCPv4 vs. DHCPv6/SLAAC) that must each be independently enabled and functional.

Memory tip: Think "pool type ≠ protocol enablement" - a dual-stack pool just means the address space supports both families, but the STA still needs the right services (DHCPv6, RA) active to actually receive an IPv6 lease.
