Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions:

1. In the network shown in the figure, OSPF protocol is run between R1, R2, and R3. IBGP neighbor relationship is established between R1 and R3 using loopback interface. If OSPF is shut down on R2's GE0/0/1 interface through "undo network xxxx yyyy" command, and BGP neighbor relationship is checked on R1, by default, the longest time for R1 BGP neighbor relationship to change from Up state to Dom state is which of the following?

A) 180s
B) 60s
C) 40s
D) 10s

2. An enterprise deploys iBGP across three routers (R1, R2, R3) within the same AS. R1 learns a route from an eBGP neighbor and successfully advertises it to R2. However, R3 does not receive the route from R2. All BGP sessions are established and stable. What is the most likely cause?

A) Missing next-hop-self on R1
B) iBGP split-horizon rule
C) Missing default route
D) BGP synchronization enabled

3. A campus network is connected through Huawei S series switches. The administrator has enabled the MAC drift detection function in the network. Which of the following descriptions of this function is wrong?

A) This function can report alarms, including MAC address, VLAN, hop interface and other information
B) After the switch turns on this function, it can integrate the MAC address drift information of the entire network and report the alarm
C) This function can provide interface protection actions, such as making the jump connection four Down to achieve automatic loop breaking
D) If loops may occur only in a few VLANs in the network connected to the switch, it is recommended to configure the subsequent action to withdraw the interface from the VLAN instead of turning the interface Down.

4. As shown in the figure, an enterprise hopes to achieve secure mutual visits between the headquarters and branches, as well as business isolation between the R&D area and the non- R&D area without changing the network deployment.

To meet this requirement, the administrator deploys BGP/MPLS IP VPN in the network. Which of the following descriptions of this scenario are correct? (Multiple choice)

A) Since the address space of the R&D area and the non-R&D area overlap, it is impossible to isolate the business of the two areas.
B) To isolate the R&D area and non-R&D area of the headquarters, you can set the RT value of VPN1 to 100:100 and the RT value of VPN3 to 200:200.
C) To achieve mutual access between the headquarters and the branch R&D area, you can set the ERI and IRT of VPN1 and VEN2 to 100:100.
D) To achieve mutual access between the headquarters and the branch R&D area, the RD values of VPN1 and VFN2 need to be set to the same value.

5. Use the "display current-configuration |include 10.0.2.*" command on the router to see all the information including "10.0.2" in the current configuration.

A) True
B) False
