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
