In the SNMP management model, which of the following elements defines the attributes of a managed device?
Answer(s): A
MIB (Management Information Base) defines the attributes of a managed device. The MIB is a database used for managing the devices in a network. It contains definitions of the attributes that SNMP agents can manage and allows the NMS (Network Management System) to access and manipulate those attributes.
iMaster NCE-Campus can be used as an authentication server on a WLAN to authenticate STAs.
iMaster NCE-Campus can be used as an authentication server in a WLAN (Wireless Local Area Network) to authenticate STAs (Stations). It supports various authentication protocols like 802.1X for secure authentication of devices trying to access the network.
DRAG DROP (Drag and Drop is not supported)On a WLAN, engineers can use the VLAN pool mechanism to assign access users to different VLANs, which helps reduce the number of broadcast domains and improve network performance. VLAN pools support two VLAN assignment algorithms: even and hash. Drag the advantages and disadvantages to the two algorithms.(Token is reusable)Select and Place:
Even assignment algorithm:The number of users in each VLAN is even.When STAs go offline and online again, their VLANs and IP addresses may easily change.Hash assignment algorithm:VLANs and IP addresses remain unchanged for STAs that go offline and online again.The number of users in each VLAN is uneven.
The typical characteristics of the AI era are that it focuses on data, explores data value, and improves AI efficiency. Therefore, the core requirement of AI for data center networks is speed, meaning low latency.
In the AI era, data center networks need to focus on speed and low latency because AI applications rely heavily on processing large volumes of data quickly. This low-latency requirement ensures that AI models can be trained and inferenced efficiently, helping to unlock the full value of the data.
On the campus OSPF network shown in the following figure, the interfaces connecting the five routers are GE interfaces, and their costs are not changed. The import-route command is run on R1. After the network converges, the route to the server at 192.168.1.0/24 is queried on R4. Which of the following is the cost of this route?
Answer(s): C
The OSPF cost of a route includes both the intrinsic cost of the OSPF path and any additional cost added by the import-route command.The import-route command on R1 specifies that the direct route to the 192.168.1.0/24 network is imported as a type 2 external route with a cost of 2.On R4, the route to 192.168.1.0/24 will be calculated based on the OSPF cost from R4 to R1 (which is the OSPF path), plus the cost of the imported route (which is 2). The cost from R4 to R1 is 1 (since all interfaces are GE with default cost 1).Thus, the total cost to the 192.168.1.0/24 network from R4 is:1 (R4 to R1) + 2 (imported route cost) = 3.
DRAG DROP (Drag and Drop is not supported)On a P2P IS-IS network, after a neighbor relationship is established between RI and R2, R2 finds that its LSDB is not synchronized. Then, R2 requests corresponding LSPs from RI for LSDB synchronization. The following figure shows the synchronization process. Drag the following packet types to the steps in which they are used.(Token is reusable)Select and Place:
1. P2P IIH (Point-to-Point Hello)This packet type is used during the initial stage of establishing the neighbor relationship between R1 and R2. It is used to exchange Hello packets to discover neighbors and initiate the link-state database synchronization process.2. LSP (Link State PDU)LSP packets are used by R1 to advertise its link-state information to R2 after the neighbor relationship is established. R2 requests the LSPs to synchronize its Link-State Database (LSDB) with R1.3. PSNP (Partial Sequence Number PDU)PSNP packets are used by R2 to request specific LSPs from R1. After R2 detects that its LSDB is not synchronized, it sends a PSNP to R1 to request the missing LSPs.4. CSNP (Complete Sequence Number PDU)CSNP packets are used to synchronize the entire LSDB. R2 can send a CSNP to R1 if it wants to ensure that the entire LSDB is up-to-date and synchronized.
On Huawei switches, which of the following planes provides network information and forwarding entries that are mandatory for data plane forwarding?
Control plane provides network information and forwarding entries that are mandatory for data plane forwarding. The control plane is responsible for managing routing and switching protocols, generating routing tables, and ensuring that the forwarding plane has the necessary information to forward traffic.
On a network, each router has a local core routing table and protocol routing tables. A routing entry in the local core routing table has multiple key fields. Which of the following are included? (Choose all that apply.)
Answer(s): A,B,C,D
Routing protocol preference of a route: This field specifies the priority or preference of the route based on the routing protocol. The routing protocol with the lowest administrative distance is preferred.Routing protocol that learns a route: This field indicates the routing protocol (e.g., OSPF, EIGRP, RIP) that learned the route.Inbound interface that learns a route: This field specifies the interface on which the route was learned, helping the router know the source of the route.Destination address of a route: This is the destination network for which the route is providing forwarding information.
