H3CSE-RS-SW Sample Questions:

1. The SSH protocol framework consists of multiple protocols . Which of the following is a correct description of these protocols and their roles in the SSH framework? (Multiple choice)

A) User authentication protocol completes the client's identity authentication
B) The transport layer protocol can provide support for server authentication and information integrity
C) The user encryption protocol mainly provides data confidentiality support and divides the encrypted information into several logical channels for multiplexing
D) Link layer protocol completes link availability and establishes encrypted channels and logical channels

2. In a large LAN, what functional layers is the network divided into? (Multiple choice)

A) Core layer
B) Management
C) Convergence Layer
D) Access layer

3. In PIM-DM networking, which descriptions of the router sending Graft messages are correct?
(Multiple choice)

A) The router will add the interface that receives the Graft message to the outbound interface list of the multicast entry
B) When a multicast receiver appears on a pruned router, the router does not have to wait for the next flood to forward the multicast data to the receiver.
C) The pruned router receives the IGMP Report message sent by the receiver and sends a Graft message to the RPF neighbor
D) The router that receives the Graft message will reply with a Graft-ACK message, the destination address of which is 224.0.0.13
E) Graft messages are sent in unicast mode, and the destination address is the IP address of the RPF neighbor.

4. Regarding the designated port fast switching mechanism in RSTP, which of the following is correct?
(Multiple choice)

A) The purpose of the synchronization process is to eliminate the possibility of loops locally on the bridge. All designated ports need to be blocked during the synchronization process.
B) The fast switch mechanism of the designated port must be on a point-to-point link
C) When the designated port in RSTP is in the Discarding state, it will send the RSTBPDU with the Proposal bit set
D) After the designated port receives the RST BPDU with the Proposal bit set and declares itself as the follower port, it will send the RSTBPDU with the Agreement bit set.

5. In the network connection shown in the figure, SWA and SWB are three-layer switches, running STP+VRRP, and after the initial configuration is completed, SWA is the root of STP and the master of VRRP, and SWC is the downlink access terminal of the two-layer switch. Which of the following description of the network link failure is correct?

A) When the link between SWA and SWC is disconnected, the STP topology will change, and G1/0/2 of SWC will become Forwarding
B) When the link between SWA and SWB is disconnected, the STP topology will change, and both uplink ports of SWC will become Forwarding
C) After the link between SWA and SWC is disconnected, the VRRP Master will remain unchanged, but the SWC downstream terminal will not communicate with the gateway.
D) When the link between SWA and SWB is disconnected, the VRRP Master will switch and SWB will become the new VRRP Master
