質問 # 89
On a network, each router has a local core routing table and protocol routing tables. A routing entry in the local core routing table has multiple key fields. Which of the following are included?
正解:A、B、C
解説:
Comprehensive and Detailed Step-by-Step Explanation:
* Routing Table Structure:
* Routers maintain a local core routing table and separate protocol routing tables for OSPF, BGP, etc.
* The local core routing table stores optimal routes selected based on metrics, protocol preferences, and administrative distances.
* Fields in the Core Routing Table:
* Destination Address (A): Indicates the destination network or host.
* Routing Protocol Preference (B): Determines the priority of routing protocols (e.g., OSPF > RIP).
* Routing Protocol (D): Specifies the protocol (e.g., OSPF, BGP) that contributed the route.
* Inbound Interface: This is stored in the protocol-specific routing table but not in the local core table.

OSPF neighbors have multiple states, such as Down, Init, 2-way, Loading, or Full. In which of the following states do OSPF routers negotiate the master and slave roles?
正解:A
解説:
Comprehensive and Detailed in-depth Step-by-Step Explanation:
OSPF routers establish neighbor relationships and progress through various states during the adjacency formation process. TheExStart stateis where routers negotiate the master and slaveroles. This negotiation is critical because the master initiates the Data Description (DD) packet exchange process.
Here's a breakdown of the relevant OSPF states:
ExStart State:
This is the phase where the routers determine which one will act as the master and which will be the slave.
The decision is based on theRouter IDsof the two routers. The router with the higher Router ID becomes the master.
Exchange State:
After the master-slave roles are established, the routers exchange DD packets. These packets contain summaries of the LSAs in their respective LSDBs.
2-way State:
This state indicates that bidirectional communication has been established between the two routers, but it occurs before master-slave negotiation.
Init State:
This is an early state where a router has sent a Hello packet to its neighbor but has not yet received a Hello packet in response.
Key Point:
The negotiation of master and slave roles happens exclusively in theExStart state, makingD. ExStartthe correct answer.

質問 # 91
When deploying a VRRP network, an enterprise administrator sets the virtual IP address to 192.168.1.254 and VRID to 1. Which of the following is the virtual MAC address after the network becomes stable?
正解:A
解説:
Comprehensive and Detailed Step-by-Step Explanation:
VRRP Virtual MAC Address Format:
The VRRP virtual MAC address is generated using the format:0000-5e00-01XX, whereXXrepresents the VRID in hexadecimal.
Calculation:
VRID = 1 # Hexadecimal =01.
Virtual MAC =0000-5e00-0101.
Correct Option:
C (0000-5e00-0101).

質問 # 93
As shown in the figure, data traffic is forwarded in tunnel mode along the path of STA -> HAP -> HAC -> upper-layer network before roaming. What is the flow direction of data traffic after Layer 3 roaming?
正解:A
解説:
After Layer 3 roaming, the STA's traffic is forwarded from the Foreign AP (FAP) to the Foreign AC (FAC), and then to the Home AC (HAC) before reaching the upper-layer network. This ensures that the STA remains on the same subnet without breaking existing sessions .
