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

1. See the command output of a router below. Which of the following statements is true?
< R2 > display ospf interface GigabitEthernet 0/0/0 verbose
OSPF Process 1 with Router ID 10.0.2.2
Interface: 10.0.12.2 (GigabitEthernet 0/0/0)
Cost: 1 State: BDR Type: Broadcast MTU: 1500
Priority: 1
Designated Router: 10.0.12.1
Backup Designated Router: 10.0.12.2
Timers: Hello 10 , Dead 40 , Poll 120 , Retransmit 5 , Transmit Delay 1

A) The router ID is 10.0.12.2.
B) This router is a BDR.
C) The interface IP address is 10.1.12.1.
D) The interface cost is 1500.

2. A filter named si is configured on a device using the as-path-filter command and is applied to a specified BGP peer. The detailed configurations are as follows:
csharp
Copy
[SW1] ip as-path-filter si permit _65500$
[SW1] bgp 65100
[SW1-bgp] ipv4-family unicast
[SW1-bgp-af-ipv4] peer 10.1.1.2 as-path-filter si import
After the configuration is complete, which of the following statements is true about the way the local device processes the routes received from the peer?

A) It accepts only the routes forwarded by AS 65500.
B) It accepts only the routes that last pass through AS 65500.
C) It accepts only the routes originated from AS 65500.
D) It accepts only the routes whose AS_Path contains AS 65500.

3. GRE is a Layer 2 VPN encapsulation technology that encapsulates packets of certain data link layer protocols so that the encapsulated packets can be transmitted over an IP network.

A) FALSE
B) TRUE

4. BGP routes have multiple path attributes. When a router advertises a BGP route to its peers, the route carries multiple path attributes. These attributes describe the characteristics of the BGP route and affect route selection in some scenarios. The attribute is Huawei-specific. It is valid only on the local device and is not transmitted to BGP peers. (Enter the attribute name in lowercase as it appears in the command output about the BGP routing table.)

5. A local router runs IS-IS and its command output is shown in the following figure. Which of the following statements is true?

A) S4/0/0 sends IIH packets at the interval of 30s.
B) The circuit level of S4/0/0 is Level-1.
C) The cost of S4/0/0 is 20.
D) S4/0/0 supports IPv6.
