NEW QUESTION # 86
A network engineer provides a troubleshooting report after rectifying a fault. The actual network is simplified into the one shown in the figure, where R1 and R2 both have OSPF enabled and function as the gateways of PC1 and PC2, respectively.
Given this, which of the following statements are true?
Network Topology:
* R1:
* Interface GE0/0/0: 10.0.12.1/24 (Connected to R2)
* Interface GE0/0/1: 192.168.1.1/24 (Gateway for PC1)
R2:
* Interface GE0/0/0: 10.0.12.2/24 (Connected to R1)
* Interface GE0/0/1: 192.168.1.2/24 (Gateway for PC2)
Options:
- A. R1 cannot ping 192.168.1.12.
- B. R2 cannot ping 10.0.12.1.
- C. PC1 and PC2 cannot ping each other.
- D. R1 cannot ping 192.168.1.2.
Answer: A,C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
* Understanding the network connectivity:
* R1 and R2 are connected through 10.0.12.0/24 and running OSPF in Area 0.
* PC1 (192.168.1.11/24) is connected to R1, and PC2 (192.168.1.12/24) is connected to R2.
* Analyzing each option:
* Option A: "R2 cannot ping 10.0.12.1." # Incorrect
* R2 is directly connected to 10.0.12.1/24 (R1) on GE0/0/0, so it can ping this IP without any routing issues.
* Option B: "PC1 and PC2 cannot ping each other." # Correct
* OSPF is only running between R1 and R2. There is no indication that R1 and R2 are redistributing connected routes (192.168.1.0/24 and 192.168.1.0/24) into OSPF.
* As a result, R1 does not know how to reach 192.168.1.12, and R2 does not know how to reach 192.168.1.11, making communication between PC1 and PC2 impossible.
* Option C: "R1 cannot ping 192.168.1.2." # Incorrect
* 192.168.1.2 is directly connected to R2, and if R1 can reach R2 through OSPF, then R1 should be able to ping 192.168.1.2.
* Option D: "R1 cannot ping 192.168.1.12." # Correct
* 192.168.1.12 is connected to R2, but if R2 does not advertise this network to R1, R1 has no route to reach it.
* Since PC1 (192.168.1.11) and PC2 (192.168.1.12) are on different subnets, and there's no redistribution, R1 cannot reach PC2's IP.
Key Takeaways and Fix Recommendations:
* To allow PC1 and PC2 to communicate, R1 and R2 must advertise their directly connected networks (192.168.1.0/24) in OSPF using the network command or by redistributing connected routes into OSPF.
* Command example:
makefile
CopyEdit
R1:
router ospf 1
network 192.168.1.0 0.0.0.255 area 0
R2:
router ospf 1
network 192.168.1.0 0.0.0.255 area 0
* This would allow R1 to learn about PC2's network and R2 to learn about PC1's network, enabling communication.

NEW QUESTION # 94
On the network shown in the figure, the DHCP server function is enabled on GE0/0/0 of R2, and the address pool is an interface address pool.
When GE0/0/0 and GE0/0/1 of R1 function as DHCP clients, only one interface can obtain an IP address by default.
Options:
- A. TRUE
- B. FALSE
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the DHCP Process in This Scenario:
* DHCP Server on R2:
* The DHCP server is configured on interface GE0/0/0 of R2.
* The address pool is an interface address pool, meaning that IP addresses are allocated from the subnet of GE0/0/0 (i.e., 10.0.12.0/24).
* DHCP Clients on R1:
* Both interfaces (GE0/0/0 and GE0/0/1) on R1 are set as DHCP clients, meaning they will send DHCP DISCOVER messages to obtain an IP address dynamically.
* Why Only One Interface Gets an IP Address?
* Interface address pools in Huawei devices assign only one IP address per MAC address (which is typically the router's MAC).
* Since both interfaces belong to R1, they share the same MAC address when making a DHCP request.
* As a result, the DHCP server on R2 only assigns one IP address to the first requesting interface.
* The second request is ignored or denied by the DHCP server due to the duplicate MAC address issue.
Key Takeaways:
* Huawei routers using an interface-based DHCP address pool assign only one IP per MAC address.
* Since both interfaces on R1 have the same MAC, only one gets an IP.
* This behavior is expected in Huawei's HCIP-Datacom-certified DHCP configurations.
