| Question | Answer |
| Where are L2 switching and L3 routing network devices located? | Intra-VLAN (L2) switching and inter-VLAN (L3) routing |
| How may methods are available for classifying VLANs? In which scenarios does Huawei cloud computing apply? | There are 4. a) Port-based VLAN b) Mac address-based VLAN c) Protocol-based VLAN d) Subnet-based VLAN. Huawei scenarios: a) VMM (Hypervisor) implement layer 2 isolation between deparments, with port groups to configure VM LANs. b) On FusionSphere, use vSwitch configured with virtual ports |
| How many QoS service models are available? In which scenarios does Huawei cloud computing apply? | There are 3. a) Best-Effort service model b) Integrated service (IntServ) model c) Differentiated service (DiffeServ) model FusionSphere uses a DVs to provide QoS for interfaces and groups. |
| Describe the QoS queuing algorithm mechanisms | Such as FIFO, priority queuing (PQ), custom queuing (CQ), and weighted fair queuing (WFQ) are used to buffer and schedule packets, thereby implementing congestion management. |
| What are stacking and clustering? | Stacking: Multiple physical switches are integrated as a logical stacked switch using stack cables. Clustering: Multiple connected switches (cascade or staked) are managed as a logical device. The administrator switch is used to centrally manage and monitor member switches. |
| Describe the role of AD | Active Directory is a centralized directory managment service used in Microsoft Windows server for large and medium-sized network enviroments. Is used to store such objects as user accounts, groups, printers, and shared folders. |
| Describe the role and mechanisms of DHCP | Dynamic Host Configuration Protocol is a LAN protocol running at the UDP layer assign dynamic addresses to clients on the internet. Mechanism: 1. Discovery: The DHCP client searches for a DCHP server. 2. Provisioning: The DCHP server provides an IP address. 3. Selection: The DHCP client selects the IP address provided by the DHCP server. 4. Confirmation: The DHCP server confirms the IP address it provided by the DHCP client. |
| Describe the role of DNS | Domain Name System ia a distributed database supporting the traslation between domain names and IP addresses, thereby, implementing network access. |
| The DiffServ model, based on the RSVP protocol, reserves resources for business applications through the network to ensure quality of service (true or false) | F |
| Which of the following types can VLANs be classified into? a. Port-based VLAN b. Subnet-based VLAN c. MAC address-based VLAN d. Protocol-based VLAN | ABCD |
