ACSP - Aruba Certified Switching Professional IPv6 and Tunneling Technologies Questions and Answers Flashcards

On AOS-CX, which global configuration command must be issued to enable IPv6 unicast routing?

Answer: ipv6 unicast-routing

The `ipv6 unicast-routing` command enables IPv6 routing globally on AOS-CX, allowing the switch to forward IPv6 packets between interfaces.

Which AOS-CX command assigns a static IPv6 address to a VLAN interface?

Answer: ipv6 address 2001:db8::1/64

The `ipv6 address 2001:db8::1/64` command is entered under a VLAN interface context to assign a static IPv6 address on AOS-CX.

What is the role of OSPFv3 in an IPv6 network running on AOS-CX?

Answer: To dynamically route IPv6 traffic using the same link-state algorithm as OSPFv2

OSPFv3 is the IPv6 extension of OSPF that uses the same link-state algorithm but operates over IPv6 link-local addresses to provide dynamic IPv6 routing.

Which AOS-CX command displays the IPv6 neighbor cache, equivalent to the IPv4 ARP table?

Answer: show ipv6 neighbors

The `show ipv6 neighbors` command displays the IPv6 neighbor cache that maps IPv6 addresses to MAC addresses, maintained by NDP rather than ARP.

In what scenario is DHCPv6 stateless mode used in conjunction with SLAAC?

Answer: When hosts need additional parameters such as DNS server addresses that SLAAC RA messages do not provide

DHCPv6 stateless mode distributes configuration parameters like DNS server addresses to hosts that use SLAAC for address assignment, combining the benefits of both.

Which ICMPv6 message type does a router send periodically to inform hosts of network prefixes, the default gateway, and other configuration parameters?

Answer: Router Advertisement (type 134)

Router Advertisement (ICMPv6 type 134) messages are sent periodically or in response to Router Solicitations to deliver prefix and gateway information used by SLAAC.
