The customer's network connection is shown in the figure.
Among them, the IP addresses of RTA, RTB, and RTC are respectively 2.2.2.1/24, 2.2.2.2/24, 2.2.2.3/24. To realize the intercommunication between RTA, RTB and RTC, configure the following frame relay MAP on RTA correct ?
The two WAN interfaces S1/0 and S1/1 of the router MSR-1 are connected to the routers MSR-2 and MSR-3 respectively.
At the same time, the Ethernet port of MSR-1 is connected to MSR-4. All four routers have run the RIP protocol and completed routing learning correctly. All routers have started all the features of RIP to prevent loops. At this time, it is found that the MSR -2 The network 192.168.0.0 fails, then ______ after a certain period of time. (Multiple choice)
119.100.1100 1000
132.119.100.1100 1111 .... Broadcast address
13. The well-known port number of the transport layer used by TFTP is ______.
If a port running STP in the Ethernet switch receives and forwards data, receives, processes and sends BPDUs, and performs address learning, then the port should be in the ______ state.
A Layer 3 switch is connected to the GigabitEthernet0/0 interface of the customer's router MSR-1, and this Layer 3 switch is the default gateway for multiple segments of the customer's office network. At the same time, the WAN interface of the router is connected to the Internet, and there is a DNS server on the Internet to provide services for hosts in the customer's local area network. The customer's office network can access the Internet normally. Now the following ACL is applied in the inbound direction of GigabitEthernet0/0 of MSR-1 :
firewall enable
acl number 3006
rule 0 deny tcp source 192.168.1.0 0.0.0.255
rule 5 permit ip
So ______ . (Multiple choice)
