1. VRRP is implemented based on the priority and preemption functions of VRRP routers. Which of the following statements is false about the VRRP solution?
A) Even if the VRRP device is the IP address owner, it still needs to participate in the election and does not directly transition to the Master state when receiving a message indicating that the interface goes Up.
B) When preemption is disabled, a backup device does not preempt the master role even if it has a higher priority than the current master, provided that the current master is working properly.
C) The master periodically sends VRRP Advertisement packets in the VRRP group to advertise its configurations such as the priority.
D) When preemption is enabled, a backup device preempts the master role if it has a higher priority than the current master.
2. There are two types of BGP peer relationships : EBGP and IBGP . When configuring EBGP, ensure that the peer IP address is routable and the UDP connection can be correctly established.
A) TRUE
B) FALSE
3. Which of the following statements about stack split is false?
A) After a stack splits, the MAC addresses of the two stacks change immediately.
B) If the master and standby switches are still in the same stack after the stack splits, the slave switches separated from the original master and standby switches re-elect the master and standby switches due to protocol packet timeout.
C) After a stack splits, multiple stacks have the same IP address and MAC address. To prevent network faults, the stacks perform MAD detection. The stack that fails the MAD detection shuts down all physical ports except reserved ports.
D) If the master and standby switches are in two stacks after the split, the stack where the original master switch resides updates the topology and selects a new standby switch. The original standby switch becomes the master switch in the new stack and a new standby switch is elected.
4. Which of the following statements regarding the BGP error display of a router is false?
A) The error may be caused by the incorrect peer AS number.
B) The neighbor address of this router is 10.1.1.2.
C) Error Type indicates that the BGP error is caused by the neighbor relationship error.
D) The error occurred at 11:40:39 on March 22, 2010.
5. On an OSPF network, if a router receives an update of an LSA that exists in the local LSDB, the router updates the LSDB and floods the LSA.
A) TRUE
B) FALSE
