Q117. The customer’s network looks like this:
HostA—-GE0/0–MSR-1–S1/0———S1/0–MSR-2–GE0/0—-HostB
The WAN interfaces on the two routers are configured as follows:
MSR-1:
firewall enable
acl number 3000
rule 0 deny ip source 192.168.0.0 0.0.0.255
rule 5 permit ip
interface Serial1/0
link-protocol ppp
firewall packet-filter 3000 outbound
ip address 6.6.6.2 255.255.255.0
MSR-2:
interface Serial1/0
link-protocol ppp
ip address 6.6.6.1 255.255.255.0
Assuming that the IP address of HostA is 192.168.0.2/24, and the routing and other related interface configurations are correct, then _______. (Multiple choice)

Q118. An empty-configured MSR router is connected to the local LAN user through the GE0/0 interface, and directly connected to the remote router through the S1/0 interface. The IP addresses of GE0/0 interface and S1/0 interface are 10.1.1.1/24 and 172.16.1.1/30 respectively.
In order to ensure the intercommunication with remote LAN users, the following routes are configured on the MSR:
[MSR] ip route 10.20.0.0 255.255.255.0 s1/0
After the configuration, the MSR receives the data packet sent to the destination address 10.20.0.254/24. After the static route is found in the routing table, how will the MSR deal with the data packet next?

Q119. 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, and all four routers run RIP protocol.
After the network 192.168.0.0 on MSR-1 fails, MSR-1 immediately sends the update message that the route is unreachable to the other three routers. If the suppression time is not considered, then ______. (Multiple choice)

Q120. The correct statement about the STP protocol is ______. (Multiple choice)

Q121. On the MSR router, once the system time is inaccurate, you can use the ______ command to adjust the system time.

Q122. The standard physical medium of 100BASE-TX is ______.

Q123. An MSR router is connected to the Internet through the S1/0 interface, and the GE0/0 interface is connected to the LAN host. The network segment of the LAN host is 10.0.0.0/8, and there is an FTP server with an IP address of 202.102.2.1 on the Internet.
By configuring the IP address and routing on the router, the hosts in the current LAN can access the Internet normally (including the public network FTP server). Now the following configuration is added to the router:
firewall enable
acl number 3000
rule 0 deny tcp source 10.1.1.1 0 source-port eq ftp destination 202.102.2.1 0
Then apply this ACL to the inbound and outbound directions of the GE0/0 interface, then which of the following intentions can this ACL achieve?

Q124. The IP address 112.1.1.1 corresponds to the network address of the natural classification network segment.

Q125. When configuring ISDN DCC, the customer configured the following dialer-rule on his MSR router:
[MSR] dialer-rule 1 acl 3000
Which of the following statements about this configuration are correct? (multiple choice)

Q126. On the MSR router, use the ______ command to configure the NAT address pool.

Q127. The main function of the physical layer of the OSI reference model is ______.

Q128. Which of the following statements about optical fiber is wrong? (multiple choice)

Q129. In a PPP connection, what is wrong about NCP is ______.

Q130. The two MSR routers are interconnected back-to-back through their respective Serial1/0 interfaces, and the PPP link layer protocol is encapsulated on the WAN interface. The correct statement about the PPP link in this network is ______. (Multiple choice)

Q131. To configure Trunk on the link between Ethernet switches and allow the transmission of VLAN 10 and VLAN 20 information, you must configure ______ on the switch.

Q132. PPP has to go through a series of negotiation process before establishing the link, the correct negotiation sequence is ___. (Fill in the code of each step one by one, there can be no spaces in between, such as: ABC)

Q133. The router discovery function in IPv6 Neighbor Discovery Protocol refers to ______.

Q134. The role of FTP data connection includes ______. (Multiple choice)

Q135. The following ACL is configured on the MSR router:
acl number 3999
rule permit tcp source 10.10.10.1 255.255.255.255 destination 20.20.20.1 0.0.0.0 time-range lucky
Then the correct understanding of the ACL is _______. (Multiple choice)

Q136. According to the different sources, the routes in the routing table are usually divided into the following categories? (multiple choice)
