Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions:

1. Which of the following PIM protocol packets have unicast destination addresses.

A) Graft
B) Bootstrap
C) Assert
D) Register Stop

2. Route summarization can effectively reduce the number of BGP routes. However, many parameters need to be properly set when configuring BGP route summarization. Otherwise, problems such as routing loops may occur.
Which of the following statements is false about BGP route summarization?

A) If the aggregate command with detail-suppressed specified is run on a device, the device advertises only the summary route.
B) If the aggregate command is run on a device, the device advertises both specific and summary routes.
C) If the aggregate command with suppress-policy specified is run on a device, the device advertises only the specific routes that match the given routing policy.
D) If the summary automatic command is run on a device, the device summarizes subnet routes based on natural network segments.

3. In addition to numerous normal service packets, the CPUs of devices on a network may also receive large numbers of attack packets. To ensure that the CPUs can properly respond to normal services, the devices provide the local attack defense function.
Which of the following statements are true about this function? (Select all that apply)

A) The device can schedule the protocol packets to be sent to the CPU in the attack defense policy based on the protocol priorities so that the packets with higher priorities are processed preferentially.
B) To ensure that session-based application-layer data runs properly during an attack, you can configure the dynamic link protection function.
C) CPU attack defense can also take effect on the management interface of the device.
D) Regardless of the packet type, the same rate limit must be set to reduce the number of packets sent to the CPU.

A) BFD for BGP
B) BFD for static routes
C) BFD for OSPF
D) BFD for PIM

5. On a large-scale network, the BGP routing table of each device is extremely large, which overloads devices.
To address this problem, route summarization can be configured. Which of the following statements is false about BGP route summarization?

A) The AS_Set attribute helps BGP prevent routing loops that may arise during route summarization.
B) With automatic summarization, BGP summarizes routes based on natural network segments.
C) IPv6 networks support only manual summarization.
D) In manual summarization, the attributes of summary routes cannot be controlled.
