QUESTION: 18

After multicast-to-unicast conversion is enabled on an AP's air interface, which of the followings is the destination MAC address of multicast packets sent over the air interface?

Multicast MAC address
MAC address of the multicast source
Broadcast MAC address
MAC address of a STA

Answer(s): D

Explanation:

After multicast-to-unicast conversion is enabled on an AP's air interface, the destination MAC address of multicast packets sent over the air interface is changed to the MAC address of a STA that has joined the multicast group. This improves the transmission efficiency and reliability of multicast packets.

True
False

Answer(s): B

QUESTION: 20

Which of the following statements correctly arranges matching modes used by URL filtering in descending order of priority?

Exact matching > Prefix matching > Suffix matching > Keyword matching
Exact matching > Suffix matching > Keyword matching > Suffix matching
Exact matching > Suffix matching > Prefix matching > Keyword matching
Exact matching > Keyword matching > Suffix matching > Prefix matching

Answer(s): C

Explanation:

URL filtering supports four matching modes: exact matching, suffix matching, prefix matching, and keyword matching. The priority order of these modes is as follows:
Exact matching: The highest priority. An exact match means that a URL entered by a user is exactly the same as a URL in a blacklist or whitelist.
Suffix matching: The second highest priority. A suffix match means that a URL entered by a user ends with a suffix in a blacklist or whitelist.
Prefix matching: The third highest priority. A prefix match means that a URL entered by a user starts with a prefix in a blacklist or whitelist.
Keyword matching: The lowest priority. A keyword match means that a URL entered by a user contains a keyword in a blacklist or whitelist.
