H3C Constructing H3C High-Performance Campus Networks Sample Questions:
1. AAA is a management mechanism of network security, what security functions it can provide
A) Access
B) Control (ACL)
C) Authentication (Authentication)
D) Billing (Accounting)
2. Regarding the compatible operation of RSTP and STP, the following statements are correct:
A) When the RSTP switch and STP switch work together, the port connected to the STP switch will switch to STP mode
B) When the connection between the RSTP switch and the STP switch is disconnected, the port previously connected to the STP switch will automatically switch back to RSTP mode
C) When a port on the RSTP switch is switched to STP mode, the port will no longer have the rapid convergence characteristics of RSTP
D) When the RSTP switch and STP switch work together, you need to switch the working mode of the RSTP switch to STP through the command stpmode stp
3. The following statements about the PIM SM registration suppression timer are correct (choose one or more)
A) The DR router of the multicast source will maintain a registration suppression timer. If the timer expires, the DR will unicast multicast source registration messages to the RP
B) To prevent the registration suppression timer from expiring, the DR will send the Register message encapsulating the multicast data to the RP before the timer expires
C) After receiving the registration stop message, the DR will update the registration suppression timer and continue to send data in multicast mode
D) After the RP receives the registration message from the DR, it will send a registration stop message and update the local (S, G) and (*, G) entries
4. What is correct about IGMP Snooping?
A) Port quick leave means that when the switch leaves the IGMP Leave message, it directly deletes the port from the outgoing port list of the corresponding forwarding entry
B) The unknown multicast group dropping function can be enabled on the switch. When the switch receives unknown multicast data packets, it will only forward to its router port and not broadcast in the VLAN.
C) Both IGMP & IGMP Snooping can be configured in the same VLAN
D) Using the iIGMP Snooping function on the Layer 2 device can establish and maintain multicast forwarding entries at the data link layer, so that multicast data can be forwarded normally at the data link layer
5. The RRPP ring main ring 1 is formed on the customer LAN switches SWA, SWB, and SWC, which can be known from the above information
A) If the switch SWA is the master node, a Common-Flush-FDB message is sent in the Failed state to notify all transmission nodes to refresh FDB
B) If the switch SWB is a transmission node and is in the Preforwarding state, it cannot receive the CommonFlush-FDB message from the master node within the specified time, and releases the temporarily blocked port by itself
C) If the switch SWB is a transmission node and is in the Preforwarding state, it cannot receive the Complete-Flush-FDB message from the master node within the specified time, and releases the temporarily blocked port by itself
D) If the switch SWA is the master node, it sends a Complete-Flush-FDB message in the Failed state to notify all transmission nodes to refresh FDB
