Dynamic Routing Protocols Overview:

Dynamic routing protocols enable routers to exchange routing information dynamically, allowing them to adapt to changes in the network topology automatically.

Explanation of Each Protocol:

OSPF (Open Shortest Path First):A link-state routing protocol that uses the Dijkstra algorithm to calculate the shortest path to destinations. It is widely used in enterprise networks.

IS-IS (Intermediate System to Intermediate System):Another link-state routing protocol, similar to OSPF, but primarily used in service provider networks.

RIP (Routing Information Protocol):A distance-vector routing protocol that uses hop count as its metric. It is simple but less scalable compared to OSPF and IS-IS.

BGP (Border Gateway Protocol):A path-vector routing protocol used for inter-domain routing (e.g., between autonomous systems). It is the backbone of the Internet.

Conclusion:All four options (OSPF, IS-IS, RIP, and BGP) are dynamic routing protocols.

TheUSG6000E-Bfirewall doesnotsupport hardware bypass by default. If hardware bypass functionality is required, anexternal bypass devicemust be purchased and configured.Hardware bypass ensures network continuity in case of a firewall failure by physically rerouting traffic around the device. Since this feature is not included by default in the USG6000E-B, additional hardware is necessary to achieve it.

Huawei'sSD-WAN solutionsupports multiple networking models to meet diverse enterprise requirements:

Hub-spoke networking:Centralizes traffic through a hub site, ideal for security and policy enforcement.

Hierarchical networking:Organizes sites into tiers (e.g., regional hubs and branches), enabling scalable architectures.

Partial-mesh networking:Connects critical sites directly while routing other traffic through hubs, balancing performance and cost.

Full-mesh networking:Provides direct connections between all sites, ensuring optimal performance for latency-sensitive applications.

Intelligent HQoSis not a networking model but rather a feature that enhances Quality of Service (QoS) across any of these models.

Virtual Systems and SSL VPN Licenses:

Virtual systems allow a single firewall to act as multiple logical firewalls, each with its own policies and resources.

Concurrent SSL VPN users require licenses for secure remote access.

Default Licensing for USG6000F Series:

By default, the USG6000F series providesfree licenses for 10 virtual systems. However,SSL VPN licenses are not included by defaultand must be purchased separately.

Conclusion:The statement is FALSE because only 10 virtual systems are provided for free, while SSL VPN licenses are not included by default.

Moderndata center networksrequirehigh scalability and efficiencyto handle cloud computing workloads. Key requirements include:

Support for large-scale server connectivity(tens or hundreds of thousands of servers).

High-bandwidth networking(100G/400G Ethernet links).

Automated network managementusing AI-driven controllers likeiMaster NCE-Fabric.

Software-Defined Networking (SDN)for dynamic traffic optimization.
