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)

HostA can ping 6.6.6.2, but cannot ping 6.6.6.1

HostA can’t ping 6.6.6.2, and also can’t ping 6.6.6.1

HostA can ping 6.6.6.2, and it can also ping 6.6.6.1

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?

The packet is discarded because the destination host is not listed in the routing table

The packet is discarded because the next hop address is not listed in the routing table

Encapsulate the IP packet into a frame conforming to the S1/0 interface link, and then forward it from the S1/0 interface

Parse the MAC address of the S1/0 interface, update the destination MAC address, and then re-encapsulate the IP packet

Find the IP address corresponding to interface S1/0, and then forward the IP packet from interface S1/0

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)

RIP’s fast convergence mechanism is used on MSR-1

The trigger update mechanism of RIP is used on MSR-1

If MSR-1 has not had time to send the update information about this route, and it receives periodic route update information from neighboring routers, then the wrong routing information will be updated on MSR-1

This method of sending update messages immediately cannot completely avoid routing loops when used alone

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

The BridgeID value is a combination of the priority of the bridge and the MAC address of the bridge. The front is the MAC address, and the back is the priority.

The default priority value of the H3C Ethernet switch is 32768

The higher the priority value, the lower the priority

When the priority is the same, the larger the MAC address, the higher the priority

The smaller BridgeID value will be selected as the root bridge

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

time

clock

clock datetime

set datetime

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?

The host whose source address is 10.1.1.1 is prohibited from initiating FTP connection to the destination host 202.102.2.1

Only prohibit the FTP control connection from the host whose source address is 10.1.1.1 to the destination host’s 202.102.2.1 whose port is TCP 21

Only prohibit the FTP data connection from the host whose source address is 10.1.1.1 to the destination host 202.102.2.1 whose port is TCP 20

There is no restriction on the FTP connection initiated from 10.1.1.1 to 202.102.2.1

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:

Only packets matching ACL 3000 can trigger dialing

Only data packets matching ACL 3000 will be sent by the router through the dial-up link
