H3CSE-RS-SW - GB0-372-ENU무료 덤프문제 풀어보기

A. For the Underlay network, the data packets of the Overlay network are just forwarding of the tunnel endpoint address, so the MAC address specification requirements of the Underlay network (especially the access switch) are greatly reduced.

B. Overlay network only needs edge devices to support Overlay, and the middle Underlay network can use traditional devices, which can protect existing investments and facilitate technology implementation.

C. Overlay expands the number of isolation identification bits. Compared with using VLAN to achieve network isolation, the isolation capability of Overlay network is greatly improved.

D. Overlay encapsulates the Layer 2 message in the IP message, allowing the virtual machine to achieve Layer 2 intercommunication across the Layer 3 network

A. The switch SWC immediately switches to the Failed state and releases the secondary port.

B. The switch SWA immediately switches to the Failed state and releases the secondary port

C. If the switch SWD finds that the port GigabitEthernet2/0/1 is Up again, it will immediately unblock the port.

D. SWA will send a Link-Down message to notify all nodes

A. Port Ethernet1/0/1 is a Trunk port, allowing data frames from any VLAN to pass through.

B. Port Ethernet1/0/1 is a Trunk port that only allows data from VLAN 1 and VLAN 10 to pass through.

C. When a data frame without a VLAN tag enters port Ethernet1/0/1, it will be tagged with VLAN1.

D. Data with VLAN1 tag will not be stripped when it leaves port Ethernet1/0/1.

A. PIMSSM can be simply seen as similar to PIMSM. When the host sends a join message, the device sends a (*, G) join message to the multicast source.

B. The multicast message reaches the receiver along the SPT between the multicast source and the receiver

C. To be compatible with earlier versions of IGMP, the receiver in PIMSSM also uses IGMP V2 to send join messages.

D. Compared with PIMSM, PIMSSM does not require RP and improves packet forwarding efficiency

A. The data frame with VLAN10 tag will not be stripped when it leaves port Ethernet 1/0/1.

B. The data frame with VLAN10 tag is discarded when it enters port Ethernet 1/0/1

C. Data frames with VLAN1 tags will be discarded when they enter port Ethernet 1/0/1

D. The data frame with VLAN10 tag will be stripped of the tag when it leaves port Ethernet 1/0/1

A. Link aggregation

B. RRPP

C. Smart Link

D. STP

A. Convergence Layer

B. Core layer

C. Access layer

D. Management

A. Complex routing strategies

B. Access security control

C. Has a large number of interfaces for connecting to end-user computers

D. High-speed packet switching

A. The longest match switch uses hardware table entries to replace the software routing table, and follows the longest match principle when searching. Even in the case of extremely serious network worms, it can still ensure the line-speed forwarding of IP packets.

B. The longest matching switch searches the routing table through software.

C. Exact match switches use software to look up routing tables and forward packets one by one

D. The accurate matching switch forwards the subsequent packets through hardware after the first packet is searched and processed by software, but it cannot cope with the impact of worm viruses on routing.

A. PCA's message enters from SWA's Ethernet1/0/1 port and exits from Ethernet1/0/3 port with VLAN Tag VLAN 1

B. The PCA message enters from the Ethernet1/0/1 port of SWA and comes out from the Ethernet1/0/3 port with the VLAN Tag of VLAN2

C. PCA's message enters from SWA's Ethernet1/0/1 port and exits from Ethernet1/0/3 port without a tag

D. The PCA message enters from the Ethernet 1/0/1 port of SWA and comes out from the Ethernet 1/0/3 port with the VLAN Tag of VLAN 10.

A. Two IMC servers cannot work in master-slave mode

B. By default, the IP address of the RADIUS server on the S3610 is 192.168.1.1

C. If the two IMC servers can adopt the master-slave mode, then the two RADIUS server IP addresses configured on the S3610 must be the same

D. When configuring the S3610, the RADIUS server type that should be selected should be Extend.

A. In the figure, by default, SWA port E1/0/1 needs to wait twice the Forward Delay time before it can enter the Forwarding state.

B. In MSTP, the downstream device will respond to the BPDU with the Agreement bit set only after receiving the BPDU with both the Proposal and Agreement bits set from the upstream device.

C. Both RSTP and MSTP require that the designated port of the upstream device can only perform rapid migration after receiving the Agreement message from the downstream device.

D. By configuring stp no-agreement-check on the port, the MSTP switch will not check whether the Agreement bit is set in the Proposal BPDU sent from the upstream.

A. Four Ethernet ports are added to the same aggregation group through static aggregation, and the Selected ports are all four ports.

B. Four Ethernet ports are added to the same aggregation group through static aggregation. The selected ports are Ethernet 1/0/1 and Ethernet 1/0/3.

C. Four Ethernet ports are added to the same aggregation group through static aggregation. The selected ports are Ethernet 1/0/3 and Ethernet 1/0/4.

D. Four Ethernet ports are added to the same aggregation group through static aggregation. The selected ports are Ethernet 1/0/1 and Ethernet 1/0/2.
