Two MSR routers are directly connected back-to-back through Serial1/0, and one of the MSR routers sees the following configuration: ★
interface Serial1/0
ip address 8.8.8.2 255.255.255.0
#
interface GigabitEthernet0/0
port link-mode route
ip address 100.1.1.2 255.255.255.0
#r
ip 1
version 2
network 0.0.0.0
#
ip route-static 0.0.0.0 0.0.0.0 8.8.8.1
Assuming that both routers are correctly configured with RIP and all interfaces are UP, which of the following analyses are correct about this configuration?

• A.A RIP default route will be sent from the outgoing interface Serial1/0 to the peer neighbor
• B.The opposite neighbor router can only receive one RIP route
• C.RIP routing update packets can only be sent or received from the Serial1/0 interface of the router
• D.The neighboring router at the opposite end cannot learn the default route generated by RIP from this router

On the MSR router, you can see the following display in the routing table:
Destination/Mask Proto Pre Cost NextHop Interface
127.0.0.0/8 Direct 0 0 127.0.0.1 InLoop0
127.0.0.1/32 Direct 0 0 127.0.0.1 InLoop0
192.168.96.0/19 Direct 0 0 192.168.120.153 S6/0
Then the correct description of the route with the destination address of 192.168.96.0/19 is ______.

• A.This is a manually configured static route with a metric value of 0
• B.This is a direct route with a metric value of 0
• C.The next hop of the router, that is, the IP address of the peer device is 192.168.120.153
• D.The interface IP address of S6/0 on this router is 192.168.120.153

A Layer 3 switch is connected to the GigabitEthernet0/0 interface of the customer's router MSR-1, and this Layer 3 switch is the default gateway for multiple segments of the customer's office network. At the same time, the WAN interface of the router is connected to the Internet, and there is a DNS server on the Internet to provide services for hosts in the customer's local area network. The customer's office network can access the Internet normally. Now the following ACL is applied in the inbound direction of GigabitEthernet0/0 of MSR-1 :
firewall enable
acl number 3006
rule 0 deny tcp source 192.168.1.0 0.0.0.255
rule 5 permit ip
So ______ . (Multiple choice)

• A.Customers on the 192.168.1.0/24 network segment cannot open external web pages through WWW
• B.Customers on the 192.168.1.0/24 network segment cannot send and receive external mail through mail clients such as Outlook
• C.Customers on the 192.168.0.0/24 network segment can download data from the Internet via FTP
• D.Customers on the 192.168.1.0/24 network segment can send and receive external mail normally through mail clients such as Outlook
