QUESTION 38
The following description of the characteristics of the router is correct ______. (Multiple choice)

QUESTION 39
A network connection is like:
HostA—-GE0/0–MSR-1–S1/0———S1/0–MSR-2–GE0/0—-HostB
Two of the MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their S1/0 interfaces, and their GE0/0 interfaces are respectively connected to the client hosts HostA and HostB. By configuring the IP address and routing, HostA can communicate with HostB in the current network. The IP address of HostA is 192.168.0.2/24, and the default gateway is 192.168.0.1. The GE0/0 interface address of MSR-1 is 192.168.0.1/24.
The following configuration has been added to MSR-1:
firewall enable
firewall default permit
acl number 3003
rule 0 deny icmp source 192.168.0.2 0 icmp-type echo-reply
interface GigabitEthernet0/0
firewall packet-filter 3003 inbound
So ______ . (Multiple choice)

QUESTION 40
Normally, the router will fragment packets whose length is greater than the interface MTU.
In order to detect the line MTU, you can ping the destination address with the ______ parameter.

QUESTION 41
On the MSR router, the -tos parameter of the ping command specifies the value of the ToS (Type of Service) field in the ICMP Echo Request message, the value range is 0~255, and the default value is ______.

QUESTION 42
The two branches of XYZ company are located in different regions, and a wide area network connection must be established between them. According to the plan, the WAN adopts the PPP protocol. Considering network security, it is required that password-type message information is not allowed to be transmitted in clear text on the network. Then which PPP authentication protocol should be adopted?

QUESTION 43
The port Ethernet1/0/4 of the switch SWA is connected to a router.
If the administrator wants to disable the spanning tree function on this port, which of the following commands needs to be used?

QUESTION 44
The router discovery function in IPv6 Neighbor Discovery Protocol refers to ______.

QUESTION 45
Which of the following protocols may run between a frame relay DTE device and a frame relay switch?

QUESTION 46
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.

QUESTION 47
Use the display nat session command to view the NAT information, the display is as follows:
There are currently 4 NAT sessions
Protocol GlobalAddr Port InsideAddr Port DestAddr Port
-198.80.28.11 — 10.0.0.2 — — —
VPN: 0, status: NOPAT, TTL: 00:04:00, Left: 00:04:00

VPN: 0, status: NOPAT, TTL: 00:01:00, Left: 00:00:59
1 198.80.28.11 512 10.0.0.2 512 198.80.29.4 512
VPN: 0, status: NOPAT, TTL: 00:01:00, Left: 00:01:00

QUESTION 50
The following routing information is seen on the MSR router running RIP:
<MSR>display ip routing-table 6.6.6.6
Routing Table: Public
