Huawei Updated H19-301_V3.0 Exam Questions and Answers by zofia

YANG (Yet Another Next Generation) is adata modeling languageused to define the structure of configuration and state data manipulated by network management protocols.

NETCONF (Network Configuration Protocol)is a network management protocol thatrelies on YANGto provide a standardized way to configure and manage network devices.

YANG defines the structure, while NETCONF provides the transport mechanism to read, modify, and delete configurations.

Other options explained:

SNMP(Simple Network Management Protocol) is used for monitoring but doesnotuse YANG.

CLI(Command-Line Interface) is a manual method for device configuration andnot standardized by YANG.

Telemetryis used for real-time data streaming but isnot dependent on YANG.

While Huawei'sUSG series firewallsinclude basicanti-DDoS capabilities, they are not designed to completely replace standaloneanti-DDoS products. Firewalls primarily focus on access control, threat prevention, and policy enforcement, whereas dedicated anti-DDoS solutions offer advanced features like large-scale traffic scrubbing, anomaly detection, and mitigation for massive DDoSattacks.For environments facing sophisticated or volumetric DDoS threats, standalone anti-DDoS appliances or cloud-based services are recommended to complement firewall capabilities.

Autonomous Driving Network (ADN) Levels:

The ADN standard defines six levels (L0 to L5), ranging from manual operations (L0) to fully autonomous operations (L5).

Highest Level (L5):

AtL5, the network achieves full autonomy, capable of self-configuration, self-optimization, and self-healing without human intervention.

Conclusion:The statement is TRUE because the highest level of the ADN standard is indeed L5: full autonomous network.

Let us analyze each statement in detail:

The CloudEngine S5731-S supports VXLAN and can be used for VXLAN deployment across core and access layers : This statement is false . The CloudEngine S5731-S series does not support VXLAN. VXLAN capabilities are typically found in higher-end switches like the S5731-H or S6730-H series.

The CloudEngine S6730-H24X6C/S6730-H48X6C supports six 100GE ports, which can be auto-negotiated to 40GE ports : This statement is true . The S6730-H series switches support six 100GE ports that can be auto-negotiated to 40GE ports, providing flexibility for high-speed connectivity.

The CloudEngine S5731-H supports native AC and can be used as the core of a small-sized network : This statement is true . The S5731-H series supports native Access Controller (AC) functionality, enabling it to act as the core switch in small-sized networks while managing wireless APs.

The CloudEngine S8706 switch supports four independent service slots and two main control board slots with service ports : This statement is false . The S8706 switch supports six independent service slots and two main control board slots. The description provided in the statement is incorrect.

Thus, the correct answers are B and C .
