300-410 Practice Question: Runs the following command to verify IPv6…
A network engineer runs the following command to verify IPv6 access-list hits:
R1# show ipv6 access-list FILTER | include matches
permit ipv6 2001:DB8:1::/48 any sequence 10 (10 matches)
deny ipv6 2001:DB8:2::/48 any sequence 20 (5 matches)
permit ipv6 any any sequence 30 (100 matches)What does this output indicate?
⚠ Common exam trap
Cisco often tests the misconception that hit counts on a deny entry mean the traffic was permitted, but in reality, the hit count indicates how many packets matched that deny rule and were dropped.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
5 packets from 2001:DB8:2::/48 have been denied, and 110 packets have been permitted.
The output shows the hit counts for each ACL entry: sequence 10 has permitted 10 packets from 2001:DB8:1::/48, sequence 30 has permitted 100 packets from any source, and sequence 20 has denied 5 packets from 2001:DB8:2::/48. The total permitted packets are 10 + 100 = 110, and the denied count is 5, matching the statement in A.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
5 packets from 2001:DB8:2::/48 have been denied, and 110 packets have been permitted.
Why this is correct
Correct. 5 matches on the deny entry, and 10+100=110 matches on permit entries.
- ✗
All packets from 2001:DB8:2::/48 have been permitted.
Why it's wrong here
Incorrect. The deny entry has matches, indicating packets were denied.
- ✗
The access list has been applied to an interface but not used.
Why it's wrong here
Incorrect. The match counters show it has been used.
- ✗
The access list is invalid because of the order of entries.
Why it's wrong here
Incorrect. The order is valid; deny before permit any is common.
