IP route-static 192.168.2.0 255.255.255.0 3.3.3.2

IP route-static 192.168.3.0 255.255.255.0 3.3.3.2

IP route-static 192.168.4.0 255.255.255.0 3.3.3.2

Among them, the 192.168.0.0/22 subnet is the LAN user network segment of MSR-2. So which of the following descriptions are wrong? (Multiple choice)

These four routes will be written into the routing table of MSR-1

Only the fourth route will be written to the routing table of MSR-1

These four routes can be replaced by one route ip route-static 192.168.1.0 255.255.252.0 3.3.3.2

Only the first route will be written to the routing table of MSR-1

136. The interface information of a router is displayed as follows:

Serial0/0 current state: UP

Line protocol current state: DOWN

Physical layer is synchronous, Baudrate is 64000 bps

Interface is DCE, Cable type is V35, Clock mode is DCECLK

So what protocol might be encapsulated or running on this interface? (Multiple choice)

PPP

HDLC

Frame Relay

RIP

None of the above answers are correct

137. The Ethernet port Ethernet0/0 of router MSR-1 is configured as follows:

Interface Ethernet0/0

IP address 192.168.0.1 255.255.255.0

A layer 3 switch is connected to this interface, and this layer 3 switch is the default gateway for multiple network segments of the customer's office network. For security reasons, the customer now requires configuration on the interface Ethernet0/0 of MSR-1. ACL (does not restrict application direction) to prohibit all users on the office network from pinging 192.168.0.1. Which of the following configurations can be used? (Multiple choice)

acl number 3000 Rule 0 deny icmp destination 192.168.0.1 0 icmp-type echo-reply

acl number 3000 Rule 0 deny icmp destination 192.168.0.1 0 icmp-type echo

acl number 3000 Rule 0 deny icmp destination 192.168.0.1 0

acl number 3000 Rule 0 deny ip destination 192.168.0.1 0 eq icmp

138. Which of the following statement about Frame Relay address mapping is correct? (Multiple choice)

Frame Relay address mapping associates the DLCI of the local device with the DLCI of the peer device.

When carrying the IP protocol, Frame Relay address mapping is used to associate the next hop IP address with the local DLC

Frame Relay address mapping can be configured manually.

Frame Relay address mapping can be dynamically maintained using Inverse AR

139. Two MSR routers are connected through Ethernet and serial interfaces respectively, as shown in the figure. The PPP link layer protocol runs on the serial link, OSPF runs on the two routers, and both belong to Area 0. At the same time, the three network segments on each router (GE interface network segment, serial interface segment, LAN segment) are released in Area 0 through the network.

Currently, the OSPF neighbor status at both ends is stable, then ______. (Multiple choice)

If the OSPF Cost value is not modified, the LAN segment from RTA to RTB will prefer the GE link.

As long as the OSPF Cost values of the GE interface and serial interface of the two routers are correctly modified, two equal-value routes to the other party's LAN will be formed on RTA and RT

On the GE link, RTA and RTB will still elect DR and BD

All the above statements are correct

140. SSH uses the TCP port number ______ by default.

Page 15 of 15

141. An enterprise network administrator needs to set a subnet mask to divide the Class C network 211.110.10.0 he is responsible for into at least 10 subnets. How many subnet masks can be used for division? (Multiple choice)

142. 0.0.0/8 XXX 100 48 10.10.10.2 S6/1

Which of the following description of this routing information is correct? (Multiple choice)

The value of Proto in this routing entry may be OSPF

The value of Proto in this routing item may be static

This route must be learned through dynamic routing

This route must not be a directly connected route

143. Two MSR routers MSR-1 and MSR-2 are connected through the WAN and dynamically complete remote route learning through RIPv2. After stabilizing for 2 minutes, MSR-1 receives a RIP update message from MSR-2, which contains a route with a Cost of 14, then ______. (Multiple choice)

If the route does not originally exist in the MSR-1 routing table, the route will definitely be added to the MSR-1 routing table.

If the routing table of MSR-1 originally contains the route and its Cost is less than 14, then the routing entry will not be updated on MSR-1.

If the routing table of MSR-1 originally contains this route, the routing entry will be updated only when its Cost is greater than 14.

If the routing table of MSR-1 originally contains the same route received from the neighbor and its Cost is less than 14, the route will also be updated.

144. The network environment is as shown in the figure. Make the following NAT configuration on the router RTA:

[RTA]acl number 2000

[RTA-acl-basic-2000] rule 0 permit source 100.0.0.0 0.0.0.255

[RTA]nat address-group 1 200.76.28.11 200.76.28.20

[RTA]interface Ethernet0/1

[RTA-Ethernet0/1]nat outbound 2000 address-group 1 no-pat

After configuration, if Client_A and Client_B access the Server at the same time, the contents of RTA's NAT table may be ______.

A)

Option A

Option B

Option C

Option D

145. Two empty-configured MSR routers RTA and RTB are interconnected back-to-back through their respective Serial1/0 interfaces.

Make the following configurations on both routers:

RTA:

[RouterA-Serial1/0] link-protocol fr ietf

[RouterA-Serial1/0] ip address 10.1.1.1 30

[RouterA-Seria11/0] fr map ip 10.1.1.2 30

RTB:

[RouterB-Serial1/0] link-protocol fr ietf

[RouterB-Serial1/0] interface serial0/0.1

[RouterB-Serial1/0.1] ip address 10.1.1.2 30

[RouterB-Serial1/0.1] fr map ip 10.1.1.1 30

The physical link between routers is good, which of the following statement is correct? (Multiple choice)

DLCI is not configured on both routers, and RTB cannot be pinged on RT

Unable to ping 10.1.1.2 on RTA

Can ping 10.1.1.2 on RTA

In the above configuration, if you only change the type of sub-interface serial0/0.1 on RTB to P2MP, then 10.1.1.2 cannot be pinged on RT

In the above configuration, if you only change the type of sub-interface serial0/0.1 on RTB to P2MP, then you can ping 10.1.1.2 on RT

146. The rate of D channel in ISDN BRI is ______.

54 Kbps

64 Kbps

36 Kbps

16 Kbps
