The two routers RTA and RTB are interconnected back-to-back using serial ports. The serial port of RTA is configured with HDLC protocol, and the serial port of RTB is configured with PPP protocol.
Both devices are configured with the correct IP address, then what will happen is ______. (Multiple choice)

• A.RTB serial port physical layer up, protocol layer down
• B.RTA serial port physical layer down, protocol layer down
• C.The physical layer of the RTA serial port is up, and the protocol layer remains up, but RTA cannot ping RTB
• D.The physical layer of the RTB serial port is down, and the protocol layer is down.
• E.The physical and protocol layers of RTA and RTB serial ports are both down

In the process of establishing a PPP session, when the physical layer is available, the PPP link enters the ______ phase.

• A.Dead
• B.Establish
• C.Authentication
• D.Network
• E.Terminate

The address of the GE0/0 interface of the router MSR-1 is 192.168.100.1/24. This interface is connected to a Layer 3 switch, and this Layer 3 switch is the default gateway for multiple network segments of the customer's office network. MSR-1 is connected to the Internet through the serial port S1/0. The entire network has been interoperable normally, and office network users can access the Internet.
For security reasons, it is necessary to prohibit the client host from pinging the GE0/0 interface of MSR-1, so the following ACL is configured on the router:
acl number 3008
rule 0 deny icmp source 192.168.1.0 0.0.0.255
At the same time, the ACL is applied in the inbound direction of GE0/0. It is found that users on the 192.168.0.0/24 network segment in the LAN can still ping the GE0/0 interface address. According to the above information, _______ can be inferred.

• A.The ACL is applied in the wrong direction
• B.The default firewall rule is to allow
• C.After the shutdown and undo shutdown commands are executed on the interface GE0/0, the 192.168.0.0/24 network segment will not be able to ping the MSR-1 Ethernet interface address.
• D.The ACL does not take effect

Methods of VLAN division include ______. (Multiple choice question)

• A.Port-based division
• B.Division based on MAC address
• C.Division based on port attributes
• D.Division based on agreement
• E.Division based on subnet

The Ethernet port Ethernet1/0 of the customer router MSR-1 is configured as follows:
interface Ethernet0/0
ip address 192.168.0.1 255.255.255.0
This interface is connected to a three-layer switch, and this three-layer switch is where the default gateway of the network segment 192.168.7.0/24~192.168.83.0/24 of the customer's office network is located.
Now the customer requires that an ACL be configured on the MSR-1 to prohibit all users on the office network from initiating Telnet to the address 192.168.0.1 of the MSR-1, so which of the following configurations is correct?

• A.acl number 3000 rule 0 deny 255.255.255.255 0 destination 192.168.0.1 0 destination-port eq telnet interface Ethernet0/0 ip address 192.168.0.1 255.255.255.0 firewall packet-filter 3000 inbound
• B.acl number 3000 rule 0 deny 0.0.0.0 255.255.255.255 destination 192.168.0.1 0 destination-port eq telnet interface Ethernet0/0 ip address 192.168.0.1 255.255.255.0 firewall packet-filter 3000 outbound
• C.acl number 3000 rule 0 deny 0.0.0.0 255.255.255.255 destination 192.168.0.1 0 destination-port eq telnet interface Ethernet0/0 ip address 192.168.0.1 255.255.255.0 firewall packet-filter 3000 inbound
• D.acl number 3000 rule 0 deny 255.255.255.255 0 destination 192.168.0.1 0 destination-port eq telnet interface Ethernet0/0 ip address 192.168.0.1 255.255.255.0 firewall packet-filter 3000 outbound
