Which of the following are dynamic routing protocols? (Select All that Apply)
Correct Answer:
ABCD
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. References:

Which of the following deployment modes are supported by AR routers?
Correct Answer:
ABCD
Huawei'sAR routerssupport multiple deployment modes to simplify network setup and management:
USB-based deployment:Configuration files can be loaded via USB drives, enabling rapid deployment without manual intervention.
DCN deployment:Devices are automatically discovered and configured through Huawei's Device Control Network (DCN), streamlining large-scale deployments.
DHCP option-based deployment:Routers obtain configuration parameters from a DHCP server, reducing manual setup efforts.
Email-based deployment:Configuration files can be sent to devices via email, allowing remote provisioning.
These modes cater to different scenarios, ensuring flexibility and ease of deployment. References:

Which of the following switches does not support two power modules?
Correct Answer:
D
Power Module Support in Huawei Switches:
Many Huawei switches are designed with dual power module slots to ensure redundancy and reliability. However, some lower-end models may not support this feature.
Analysis of Each Switch:
S5736-S24T4XC:This switch supports dual power modules for redundancy. S5732-H:This switch also supports dual power modules.
S5731-S24P4X:This switch supports dual power modules.
S5735-L:This switch is a lower-end model anddoes not support dual power modules, making it less suitable for environments requiring high reliability.
Conclusion:The S5735-L series switch does not support two power modules. References:

Redundancy is the guarantee of stable network operation and is one of the important factors to consider when selecting an aggregation switch. How many power modules does one Huawei CloudEngine S8700-10 have?
Correct Answer:
A
The Huawei CloudEngine S8700-10 is a high-performance aggregation switch designed for enterprise campus networks. It supports up to 4 power modules , which provide redundancy and ensure stable operation even in the event of a power module failure. Redundant power supplies are critical for maintaining network uptime and reliability, especially in mission-critical environments.
The other options (2, 6, and 8) do not match the specifications of the S8700-10. While some models in the S8700 series may support fewer or additional power modules, the S8700-10 specifically accommodates up to 4 power modules.
