質問 # 16
The figure shows the simplified topology of an enterprise campus network. On this network, the aging time of dynamic MAC address entries on switches is 300 seconds. The administrator connects PC1 to GE1/0/1 of SW1 and successfully pings the IP address of PC2 from PC1. Then, the administrator disconnects the Ethernet cable of PC1 from GE1/0/1 of SW1, immediately connects the cable to GE1/0/2 of SW1, and pings the IP address of PC2 from PC1. Which of the following operations does SW1 perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1?
正解：D
解説：
An Ethernet switch learns MAC address entries dynamically by examining the source MAC address of incoming frames. When SW1 first receives frames from PC1 on GE1/0/1, it creates a MAC address table entry mapping PC1's MAC address to that port. If PC1 later sends frames that arrive on GE1/0/2, SW1 updates the learned entry to reflect the new incoming interface.
Therefore, option B is correct: SW1 saves the mapping between PC1's MAC address and GE1/0/2 and removes or overwrites the old mapping associated with GE1/0/1.
質問 # 17
DAD enables a node to detect whether an IPv6 address is already in use by another node before assigning it to an interface. This ensures that duplicate unicast addresses do not exist on a network. Which of the following packets are used for DAD? (Select all that apply)
正解：A、C
解説：
Duplicate Address Detection ( DAD ) is an IPv6 mechanism used to verify that a unicast address is not already in use before the address is assigned to an interface. DAD is implemented using Neighbor Solicitation (NS) and Neighbor Advertisement (NA) messages, which are part of the ICMPv6 Neighbor Discovery protocol. Therefore, options A and D are correct.
When a host wants to verify a tentative IPv6 address, it sends an NS message for that address. If another node on the link is already using that address, that node responds with an NA message, indicating the address is duplicated and cannot be assigned. If no NA is received within the required period, the host assumes the address is unique and can use it. Options B and C are incorrect because Router Solicitation (RS) and Router Advertisement (RA) are used for router discovery, prefix advertisement, and stateless address autoconfiguration, not for DAD itself. HCIA-Datacom emphasizes the distinction between Neighbor Discovery functions, including address resolution, next-hop reachability, router discovery, and duplicate address detection in IPv6 networks.
質問 # 18
NAPT and Easy IP translate both IP addresses and port numbers to allow multiple private IP addresses to share multiple public IP addresses.
正解：B
解説：
NAPT and Easy IP both perform port-level translation in addition to IP address translation. This allows multiple private hosts to share one or more public IP addresses by differentiating sessions using port numbers, enabling efficient IPv4 address utilization.
質問 # 19
A small enterprise's switches do not support LACP. Therefore, the administrator manually binds two links between two switches into an Eth-Trunk. Which of the following statements are false about this scenario? (Choose all that apply.)
正解：A、D
解説：
Manually configured Eth-Trunk (static aggregation) does not support dynamic link management features such as automatic link addition or load-based negotiation. If a link fails, it is simply removed from forwarding but not automatically replaced by another link, and the system does not dynamically add new active links.
Also, static Eth-Trunk operates in load-sharing mode, not active/standby mode, so both links forward traffic simultaneously under normal conditions.
質問 # 20
Which of the following are valid static route configurations?
正解：A、C、D
解説：
Option A is valid; the destination is defined in CIDR format (129.1.0.0/16) with a specified outgoing interface.
Option B is valid; it uses a subnet mask format and specifies a next-hop IP.
Option D is also valid with the destination and mask defined and a next-hop IP.
