1. In the routing table of an MSR router, which of the following sources of routes may be included? (multiple choice)

A) The static route manually configured by the network administrator
B) The route discovered by the dynamic routing protocol
C) Route of directly connected network segment
D) The route discovered by the network layer protocol

2. A network connection is like:
HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB
The two MSR routers MSR1 and MSR2 are interconnected back-to-back through their S1/0 interfaces, and their GigabitEthernet0/0 interfaces are respectively connected to the client hosts HostA and HostB. HostA can communicate with HostB in the current network by configuring the IP address and routing.
The following configuration has been added to MSR-2:
firewall enable
acl number 3000
rule 0 deny tcp destination-port eq telnet
interface Serial1/0
link-protocol ppp
ip address 1.1.1.2 255.255.255.252
firewall packet-filter 3000 inbound
firewall packet-filter 3000 outbound
interface GigabitEthernet0/0
ip address 10.1.1.1 255.255.255.0
So which of the following statements are correct? (multiple choice)

A) The firewall packet-filter 3000 outbound configured later will replace the firewall packet-filter 3000 inbound command
B) Telnet to MSR-1 on HostB successfully
C) The last configured firewall packet-filter 3000 outbound will not replace the firewall packet-filter 3000 inbound command
D) Can't successfully Telnet to MSR-1 on HostB

3. In the switching network shown in the figure, all switches have enabled the STP protocol.

According to the information in the figure, which switch will be selected as the root bridge?

A) SWA
B) SWC
C) Insufficient information, unable to judge
D) SWB

4. The equipment that realizes network interconnection at the network layer is ______.

A) Router
B) Repeater
C) Switch
D) Hub

5. A company's MSR router plans to dial-up to the Internet through ISDN DCC, and the router has the following configuration:
[H3C]dialer-rule 1 ip deny
[H3C]firewall default permit
This dialer access control list dialer-rule 1 has been quoted under the dialer interface, so which of the following statements about dialing are wrong?

A) TCP type packets can trigger dialing
B) Any IP packet can trigger dialing
C) UDP type data packet can trigger dialing
D) No IP packet can trigger dialing
