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

1. The concepts of RD and RT are introduced in BGP/MPLS IP VPN network. Which of the following descriptions about RD and RT are correct? (Multiple choice)

A) The RD value is not used to identify the origin of a route, nor is it used to determine which VPN instance the route should be added to.
B) A VPNv4 route can only contain one RD value and one RT value
C) VPNv4 address is 96 bits in total, of which the RD value is 64 bits long
D) RD is used to resolve IPv4 address conflicts before adding it to the IPv4 address.

2. MPLS needs to assign labels to messages in advance and establish an LSP before it can forward messages. LSP is divided into static LSP and dynamic LSP. Which of the following protocols can be used to establish a dynamic LSP? (Multiple choice)

A) IS-IS
B) RSVP-TE
C) LDP
D) PIM-SM

3. OSPF neighbors periodically send Hello messages to establish and maintain adjacency, and the interval of the Hello timer must be consistent, otherwise the adjacency cannot be established. In order to accelerate OSPF convergence, network engineers can set the interval of the Hello message to 1ms.

A) False
B) True

4. In a large BGP network, there are many peers, which makes configuration and maintenance extremely inconvenient. For BGP peers with the same configuration, they can be added to a BGP peer group for batch configuration, which simplifies the difficulty of management and improves the efficiency of route publishing. When configuring an IBGP peer group, you do not need to specify the AS number of the peer group. When configuring an EBGP peer group, you must specify the AS number of the peer group.

A) False
B) True

5. On an MPLS network, an LSR ID uniquely identifies an LSR. An LSR ID defaults to the IP address of a physical interface on a device and can be manually set to a loopback interface address.

A) FALSE
B) TRUE
