Free Huawei H19-402_V1.0 Exam Dumps Questions & Answers

Which of the following is not an advantage of the spine-leaf networking over the traditional networking?

• A.  The flattened network features redundancy, reliability, and high throughput, facilitating east-west network capacity expansion.
• B.  Resources are pooled between zones to avoid uneven resource distribution.
• C.  The logical two-layer architecture has a high oversubscription ratio.
• D.  Each leaf node is connected to one or two spine nodes to enable communication between all types of nodes connected to the network.

In the cloud-network integration scenario of the CloudFabric Solution, which of the following devices or platforms need to be interconnected with the SDN controller iMaster NCE-Fabric?

• A.  Cloud platform
• B.  Physical switch
• C.  VMM
• D.  Firewall

In the CloudFabric Solution, firewalls can connect to service leaf nodes or border leaf nodes (combined with service leaf nodes).

• A.  FALSE
• B.  TRUE

iMaster NCE-Fabric can manage Huawei CloudEngine switches in either in-band or out-of-band mode. In in- band mode, iMaster NCE-Fabric uses northbound interfaces to manage switches through the service network.
In out-of-band mode, southbound interfaces of iMaster NCE-Fabric are connected to the management interfaces of switches through an independent management network.

• A.  FALSE
• B.  TRUE

(Reliability design is important for the physical network design of a data center. Which of the following are true about reliability design principles?)

• A.  Peer-link fault: When the peer-link in an M-LAG fails, the DAD mechanism prevents dual master devices on the network and improves reliability.
• B.  When modular switches are deployed on the network, the inter-card connection is recommended for uplinks and downlinks, stack link, and peer-link of modular switches to implement card-level reliability.
• C.  Uplink reliability of leaf nodes: ECMP is implemented between leaf and spine nodes through multiple links.
• D.  Server link reliability: One server is dual-homed to two server leaf nodes, and NICs on a server work in load balancing or active/standby mode. If one server link fails, services are switched to the redundant or standby link.
