Free Cisco 300-410 ENARSI Actual Exam Questions - Question 5 Discussion
DRAG DROP Drag and drop the descriptions from the left onto the IPv6 first hop security features on the right. Not all options are used. 
B and C are likely the main features since they deal with RA Guard and DHCPv6 Snooping, which directly protect against rogue devices on the local link. The others seem less relevant for first hop IPv6 security.
I’d add that DHCPv6 Guard should be considered too, since it prevents rogue DHCPv6 servers, which is crucial for first hop security. Also, Device Tracking is often used to tie IP addresses to MACs on the port, helping identify devices on the network and preventing spoofing. So anything mentioning IP-MAC binding or device tracking likely matches a first hop security feature as well. The options about blocking DHCPv4 or general IPv4 stuff can be ruled out here since this is specifically IPv6 focused.
I’d rule out options that mention blocking DHCPv4 since this is about IPv6 first hop security. RA Guard definitely fits with stopping fake router ads, and DHCPv6 Snooping handles rogue DHCPv6 servers. Those seem key here.
RA Guard blocks fake router advertisements, so it fits that description well.
Looking at the options, I’d say the feature about preventing spoofed RA messages fits with RA Guard. That’s a core first hop defense against rogue routers in IPv6 environments.
Anyone else wondering if this question is about specific Cisco IOS versions? The image link doesn't show any version or context, so not sure if all these IPv6 first hop security features apply universally or are version-dependent. Also, the drag and drop part isn’t visible here, so can we confirm which features are actually included in the options? That’d help clarify how to match the descriptions correctly.
