D

DynamicNone of the provided options (A: User, B: Ephemeral, C: Private, D: Dynamic) directly correspond to the term “registered port.” In networking, registered ports are those numbered from 1024 to 49151, as defined by the Internet Assigned Numbers Authority (IANA), and are used by specific services or applications upon registration.
However, since the question requires selecting one of the given options and none accurately match, the closest related concept might be misinterpreted in the context of the question. Based on standard terminology:

Ephemeral ports (often called dynamic or private ports) are temporary ports used by clients (49152–65535).
Registered ports are not synonymous with user, ephemeral, private, or dynamic ports.

If forced to choose from the given options, none are correct, but the question may expect D: Dynamic due to occasional confusion in terminology where dynamic ports are misunderstood. However, this is not accurate for registered ports.
Final Answer: None (if allowed); otherwise, D: Dynamic (noting potential question error).Which of the following types of cables don’t need EMI shielding?

Since it has a maximum allowable hop count of 20 by default, a hop count of 21 would be deemed unreachable.
B

Since it has a maximum allowable hop count of 18 by default, a hop count of 19 would be deemed unreachable.
C

Since it has a maximum allowable hop count of 16 by default, a hop count of 17 would be deemed unreachable.
D

Since it has a maximum allowable hop count of 15 by default, a hop count of 16 would be deemed unreachable.
ChatGPT 说：

The correct answer is:

C — Since it has a maximum allowable hop count of 16 by default, a hop count of 17 would be deemed unreachable. ✅

Explanation:
RIP (Routing Information Protocol) uses hop count as its routing metric. The protocol defines:

Maximum hop count = 15

Any destination with a hop count of 16 is considered unreachable

So if a route’s hop count exceeds 16 (i.e., 17), RIP will treat it as unreachable. This is a fundamental limit designed to prevent routing loops.

Option D is a common distractor because it flips the numbers, but RIP’s limit is 15 hops.
