NO.154 The customer’s network connection looks like:
HostA—-GE0/0–MSR-1–S1/0—–WAN—-S1/0–MSR-2–GE0/0—-HostB
The two MSR routers are interconnected through the WAN, and the physical connection is now normal. The address of interface S1/0 of MSR-1 is 3.3.3.1/30, and the address of interface S1/0 of MSR-2 is 3.3.3.2/30. Now the following 4 static routes are configured on MSR-1:
ip route-static 192.168.1.0 255.255.255.0 3.3.3.2
ip route-static 192.168.2.0 255.255.255.0 3.3.3.2

ip route-static 192.168.4.0 255.255.255.0 3.3.3.2
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)

NO.156 The following statement about the functions of each layer of the OSI reference model is wrong.

NO.157 The 802.11b protocol defines 14 channels in the 2.4GHz frequency band, and there is overlap in the frequency spectrum between adjacent channels. In order to maximize the use of frequency band resources, which set of channels can be used for wireless coverage?

NO.158 Two MSR routers MSR-1 and MSR-2 are connected through the WAN and dynamically complete remote route learning through RIPv2.
After stable for 2 minutes, the RIP update message from MSR-2 is received on MSR-1, which contains the route with Cost of 14, then ______. (Multiple choice)

NO.159 The following statement about WAN is wrong. ______.

NO.160 802.1x defines the port-based network access control protocol, and only defines the point-to-point connection between the access device and the access port. The access port can only be a physical port.

NO.161 In the process of establishing a PPP session, when the physical layer is available, the PPP link enters the ______ phase.

NO.162 The correct description of the startup process of the router system in the following options is ______.

NO.163 The customer’s two MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their respective S0/0 interfaces. The frame relay protocol started and encapsulated between the S0/0 interfaces of two MSR routers, where MSR-1 is the frame relay DCE side, and MSR-2 is the frame relay DTE side.
In order to save resources, frame relay sub-interfaces are configured on both routers, which are configured as follows:
MSR-1:
interface Serial0/0.40 p2p
fr dlci 222
ip address 30.2.2.2 255.255.255.252
MSR-2:
interface Serial0/0.100 p2p
fr dlci 222
ip address 30.2.2.1 255.255.255.252
Based on this configuration, you can guess ______. (Multiple choice)

NO.164 When configuring ISDN DCC, the customer made the following configuration on his MSR router:
[MSR] dialer-rule 1 ip permit
[MSR] interface dialer 0
[MSR-Dialer0] dialer enable-circular
[MSR-Dialer0] ip address 100.1.1.1 255.255.255.0
[MSR-Dialer0] dialer-group 1
[MSR-Dialer0] dialer route ip 100.1.1.2 8810052
Which of the following statements about this configuration are correct? (multiple choice)

NO.165 Which of the following statements about frame relay are correct?

NO.166 The correct statement about STP, RSTP and MSTP is ______. (Multiple choice)

If you need to enable ARP proxy on RTA so that RTA can forward ARP packets between PCs, which of the following configurations is correct? (multiple choice)

NO.168 If the IP address of a host is 130.25.3.135 and the subnet mask is 255.255.255.192, then the network address of the subnet where the host is located is ______.

NO.169 A network connection is as follows:
HostA—-GE0/0–MSR-1–S1/0———S1/0–MSR-2–GE0/0—-HostB
The customer requires that only ICMP messages between HostA and HostB are restricted. Which of the following is feasible? (multiple choice)

NO.170 There are two hops from the source device to the destination device. Use the tracert command to detect the path. When the first hop is detected, the source device sends a UDP packet with a TTL of 1 to a larger port of the destination device. When the packet reaches the middle hop, the TTL will change to 0, so the device responds to the source device. Respond to an ICMP______ message.
