What topics are covered in the H31-161 exam?

The official Huawei HCIE-Carrier IP (Written) syllabus is organized into 7 main domains. The first three are EGP Routing, Network Operations and Troubleshooting, and MPLS and VPN Technologies. For the full domain-by-domain breakdown, see the complete Exam Topics outline above.

Huawei HCIE-Carrier IP (Written) Sample Questions:

Question 1

Which of the following statements about BFD for MPLS LSP are true?

A. BFD for MPLS LSP detects faults only on the forwarding plane. LSP Ping, however, can not only detect faults on the forwarding plane, but also find out inconsistencies between the forwarding plane and the control plain- Therefore, they are often combined for a better fault detection solution.
B. An MPLS LSP may be unidirectional .If BFD packets are transmitted along an MPLS LSP in the forward direction., these packets may be forwarded over IP in the reverse direction. Then the forward and reverse paths of a packet may be different As a result, when a fault occurs on the reverse path, BFD detects and reports the fault even if the MPLS LSP is normal.
C. In BFD for MPLS LSP, LSP Ping is used to negotiate the identifier and parameters of a BFD session.
D. If MPLS LSPs work in load balancing mode, a BFP session should be triggered on each LSP in principle. Only one BFD session. however, can be initialed for load-balancing MPLS LSPs to an intermediate node In this case, the forwarding path ol BFD packets may be different from what expected. As a result may be reported or missed.

Question 2

Exhibit:

As shown in the figure, RTA and have one BGP session. To detect fault fast, the BFD for BGP feature needs to be configured on RTA and RTB. BGP-related configurations are as follows:

The only Ethernet link between RTA and RTB becomes faulty when the BGP neighbor session is in ESTABLISHED state and the BFD session is in the UP state. Which statements is true? (Note: BFD works in asynchronous mode)

A. The BGP session between RTA and RTB is interrupted when the BGP hold time (time duration is 180s by default) express.
B. RTA detect the fault faster than RTB.
C. RTB detect the fault faster than RTA.
D. RTA and RTB detect the fault simultaneously.

Question 3

As shown in the figure, CEs connect to users 1 and 2 through access
interfaces or links.
[Quidway-GigabitEthernet1/0/4]portswitch
[Quidway-GigabitEthernet1/0/4]port link-type access
[Quidway-GigabitEthernet1/0/4]port default vlan 1
[Quidway-GigabitEthernet1/0/6]portswitch
[Quidway-GigabitEthernet1/0/6]port link-type access
[Quidway-GigabitEthernet1/0/6]port default vlan 2
[Quidway-GigabitEthernet1/0/3]portswitch
[Quidway-GigabitEthernet1/0/3]port link-type trunk
[Quidway-GigabitEthernet1/0/3]port trunk permit-pass vlan 1 to 2
Users 1 and 2 require different network transmission quality. Which of the following methods are feasible to configure 802.1p priority 1 for packets of user 1 and 802.1p priority 2 for packets of user
2?

A. On a PE, configure vlan-stacking and STC for interfaces on the private network for users 1 and 2.
B. On a PE, configure Dot1q tunnel interfaces and simple traffic classification (STC) for interfaces on the private network.
C. On a CE, configure STC for user VLANs on the user access side.
D. On a PE, configure vlan-mapping and STC for interfaces on the private network for users 1 and 2.

Question 4

As shown in the figure, RTA connects to RTB and RTC. A TE tunnel is configured on RTA to reach RTC. The TE tunnel cannot be successfully established. However, CSPFbased path calculation is successful and RTA does not receive any PathErro messages. What are possible causes?

A. Different authentication keys are configured on interfaces RTB-2 and RTC-1.
B. RSVP-TE is not configured at interface RTB-2.
C. The reserved bandwidth is insufficient at interface RTB-2.
D. An interface address on RTB is the same as the address of interface RTA-1.

Question 5

Which statement about the Ethernet clock synchronization technology used in actual solutions is true?

A. The CES packet recovery technology requires the intermediate node to support transparent clock transmission.
B. The NTP technology requires the intermediate node to support transparent clock transmission.
C. The IEEE1588 technology requires the intermediate node to support transparent clock transmission.
D. The 802.1as technology requires the intermediate node to support transparent clock transmission.
