質問 # 195
When configuring port security on a switch, the administrator also enables static MAC address flapping detection. If static MAC address flapping occurs, the switch takes the configured action to protect the interface.
Match the names of interface security protection actions with corresponding operations.
正解：
解説：
Explanation:
* Restrict # Discards the packets that trigger static MAC address flapping and reports an alarm.
* Protect # Discards the packets that trigger static MAC address flapping only and does not report an alarm.
* Shutdown # Sets the interface state to error-down and reports an alarm.
Comprehensive and Detailed In-Depth Explanation:
1. Understanding Port Security Modes
Port security is used to control access on a switch port based on MAC addresses. If a MAC address violation occurs (e.g., static MAC address flapping), the switch can take different actions based on the configured security mode.
Security Mode
Description
Restrict
Drops the violating packets and logs the violation by generating an alarm.
Protect
Drops the violating packets but does not generate an alarm.
Shutdown
Places the interface into error-disabled (error-down) state and logs an alarm.
2. Matching Each Security Mode with Its Operation
* Protect Mode:
* The switch drops the packets from the unauthorized MAC address.
* No alarm is generated or logged.
* Correct Mapping: " Discards the packets that trigger static MAC address flapping only and does not report an alarm. "
* Restrict Mode:
* The switch drops the packets from the unauthorized MAC address.
* An alarm is generated and logged in the system.
* Correct Mapping: " Discards the packets that trigger static MAC address flapping and reports an alarm. "
* Shutdown Mode:
* The switch shuts down the interface by placing it into the error-down state.
* An alarm is generated and logged.
* Correct Mapping: " Sets the interface state to error-down and reports an alarm. "
質問 # 196
On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces.
* The router ID of each router is 10.0.X.X, and the AS number is 6500X, where X is the number of the router.
* Both R1 and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import-route command.
Which of the following statements are true?
正解：A、B、C、D
解説：
Comprehensive and Detailed In-Depth Explanation:
Understanding the BGP Network Topology in the Question:
* EBGP Peering
* Each router forms EBGP peer relationships with directly connected neighbors.
* This is a fully meshed topology, meaning each router exchanges BGP routes with its adjacent routers.
* Routing Information for 192.168.1.0/24
* R1 and R4 import the static route 192.168.1.0/24 into BGP.
* Since BGP prefers the shortest AS path, traffic to 192.168.1.0/24 will follow the shortest path to R1 or R4.
Route Analysis for Each Statement:
Statement A: R6 # R5 # R4 # (Correct)
* R6 does not have a direct route to 192.168.1.0/24, so it must rely on BGP advertisements from its EBGP neighbors.
* R5 learns the route to 192.168.1.0/24 from R4.
* Therefore, R6 forwards traffic to R5, and then R5 sends it to R4.
# Correct path: R6 # R5 # R4
Statement B: R5 # R4 # (Correct)
* R5 is directly connected to R4, and since R4 advertises the 192.168.1.0/24 route via BGP,
* R5 will forward traffic directly to R4 as the shortest AS path.
# Correct path: R5 # R4
Statement C: R2 # R1 # (Correct)
* R2 is directly connected to R1 and learns the 192.168.1.0/24 route from R1 via BGP.
* Since R1 advertises the static route, R2 forwards traffic directly to R1.
# Correct path: R2 # R1
Statement D: R3 # R2 # R1 # (Correct)
* R3 is directly connected to R2 and learns the 192.168.1.0/24 route from R2 via BGP.
* Since R2 prefers R1 as the shortest AS path to 192.168.1.0/24,
* R3 will send traffic to R2, and R2 will send it to R1.
# Correct path: R3 # R2 # R1
Final Conclusion:
# A. The path for traffic from R6 to 192.168.1.0/24 is R6 # R5 # R4.# B. The path for traffic from R5 to
192.168.1.0/24 is R5 # R4.# C. The path for traffic from R2 to 192.168.1.0/24 is R2 # R1.# D. The path for traffic from R3 to 192.168.1.0/24 is R3 # R2 # R1.
Thus, the correct answers are: A, B, C, D.
