答案：B
問題 #27
In the figure, the company wants to ensure secure communication between the headquarters and branch , and isolate the R & D areas from non-R & D areas , without changing the current network deployment.
To meet this requirement, an administrator deploys BGP/MPLS IP VPN on the network .
Which of the following statements are true?
答案：A,D
解題說明：
Comprehensive and Detailed In-Depth Explanation:
To verify the correct answers, let ' s analyze how BGP/MPLS IP VPN is used for secure communication and isolation in an enterprise network.
1. Understanding BGP/MPLS IP VPN Concepts
MPLS VPN (Multiprotocol Label Switching Virtual Private Network) is used to:
* Allow communication between specific sites by using Route Targets (RTs) .
* Ensure isolation of specific areas (e.g., R & D vs. non-R & D) by controlling RT import/export policies .
* Utilize Route Distinguisher (RD) to make overlapping IP addresses unique within the VPN.
2. Analyzing the Answer Choices
# A. " To enable communication between the headquarters and branch R & D areas, both the ERT and IRT of VPN1 and VPN2 can be set to 100:100. " # TRUE
* Explanation:
* ERT (Export Route Target) and IRT (Import Route Target) define which VPNs share routing information .
* If VPN1 (HQ R & D) and VPN2 (Branch R & D) use the same RT (100:100), they will exchange routes, enabling communication.
* Correct configuration:
VPN1: ERT 100:100, IRT 100:100
VPN2: ERT 100:100, IRT 100:100
* # This is correct and enables communication between HQ and branch R & D areas.
# B. " To implement communication between the headquarters and branch R & D areas, the RDs of VPN1 and VPN2 need to be set to the same value. " # FALSE
* Explanation:
* RD (Route Distinguisher) is only used to make overlapping IP addresses unique within the MPLS VPN.
* RD does NOT control route exchange between VPNs (RTs control route exchange).
* VPN1 and VPN2 can have different RDs but still communicate if they share the same RT (100:100).
* # RDs do NOT need to be the same for VPNs to communicate.
* # This statement is false.
# C. " R & D areas and non-R & D areas have overlapping address spaces. Therefore, services in the two areas cannot be isolated. " # FALSE
* Explanation:
* Overlapping address spaces are common in MPLS VPNs and can be isolated using unique Route Targets (RTs).
* As long as VPNs have different RTs, their traffic remains isolated.
* For example:
VPN1 (R & D): RT 100:100
VPN3 (non-R & D): RT 200:200
* Even with overlapping IPs, R & D and non-R & D areas are completely isolated.
* # This statement is false.
# D. " To isolate R & D areas from non-R & D areas at the headquarters, the RTs of VPN1 can all be set to 100:100 and the RTs of VPN3 can all be set to 200:200. " # TRUE
* Explanation:
* Setting different RTs for R & D (100:100) and non-R & D (200:200) ensures complete isolation .
* Correct configuration:
VPN1 (R & D): RT 100:100
VPN3 (non-R & D): RT 200:200
* Since VPN1 and VPN3 do NOT share the same RTs, their routes remain separate.
* # This ensures isolation between R & D and non-R & D areas.
問題 #28
A router Network LSA is shown in the figure. Which of the following statements is correct? (Multiple choice)
答案：A,C,D
問題 #29
A park deployed IPv6 for business testing. There are 4 routers (R1, 22, R3 and R4) in this network, running OSPFv3 to realize the interconnection of IPv6 network. There is a new router R5 that needs to be connected to the network for testing. An engineer introduced a direct route in the OSPFvV3 process of R4 to realize that the devices in the campus network can access the GE0/0/1 port address of R5. Which of the following descriptions of the scene are correct? (Multiple choice)
答案：B,C,D
