질문 # 90
Private addresses are network or host addresses that are constrained for use within internal networks and cannot be used for Internet access directly. Which of the following IP addresses is not a private IP address?

정답：B

설명：
Private IPv4 address ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. The address
172.32.32.32 falls outside the private 172.16.0.0-172.31.255.255 range, so it is a public IP address and not a private one.


질문 # 91
During VLAN planning for a campus network, VLAN IDs for different service types must be allocated consecutively, without redundancy, to prevent omissions in future allocations.

정답：A

설명：
This statement is false. In campus network VLAN planning, VLAN IDs do not have to be allocated strictly consecutively without any gaps. In fact, leaving some reserved VLAN IDs is often a practical and recommended design approach. VLAN planning should focus on clarity, scalability, maintainability, and service separation, rather than on forcing all VLAN IDs to be contiguous.
For example, an administrator may reserve certain VLAN ranges for user access, voice services, management, wireless services, guest access, future expansion, or specific departments. Such structured planning makes later network expansion easier and reduces the risk of service conflicts or disruptive renumbering. HCIA-Datacom emphasizes that good campus network planning should consider current requirements and future growth. Consecutive allocation may look tidy at first, but it can actually reduce flexibility and make later additions more difficult.
Therefore, the idea that VLAN IDs must be assigned consecutively without redundancy to avoid omissions is not a correct design principle. Reasonable reservation and categorized allocation are often more beneficial in real enterprise campus networks.


질문 # 92
In the figure, a web client sends an HTTP request to a web server, and the router in between performs operations on the HTTP request. Which of the following statements are false about the router's operations?
(Select all that apply)

정답：B,C,D

설명：
A router works mainly at the network layer . When it receives a frame, it removes the Layer 2 header and trailer, examines the destination IP address in the Layer 3 header, consults the routing table, selects the outgoing interface, and then re-encapsulates the packet into a new Layer 2 frame for the next hop. Therefore, statement B is true and is not part of the answer.
Statement A is false because the router does not create a new destination IP address during normal forwarding. The source and destination IP addresses remain unchanged end to end unless special functions such as NAT are used. Statement C is false because routing-table lookup is based on the destination IP address, not on TCP or UDP port numbers. Statement D is also false because normal IP routing does not inspect application-layer content to determine the outgoing interface. That decision is made from the network- layer destination address and the routing table. This question tests the layered forwarding logic of routers in TCP/IP networks.


질문 # 93
The Protocol field in a packet's IP header identifies the upper-layer protocol that will continue to process the packet. For an ICMP packet, the Protocol field defaults to 0.

정답：A

설명：
The Protocol field in the IP header identifies the upper-layer protocol such as ICMP, TCP, or UDP. ICMP is identified by protocol number 1, not 0. Therefore, the statement that ICMP uses a default value of 0 is incorrect.


질문 # 94
If PC1 obtains an IPv6 address through SLAAC, which of the following is the network prefix length of the address that PC1 receives?

정답：C

설명：
In SLAAC (Stateless Address Autoconfiguration), IPv6 hosts always use a 64-bit interface identifier with a /64 network prefix. The router advertisement provides a /64 prefix, and the host generates the remaining 64 bits for its interface ID.
