Question No : 8
An MSR router connects to the Internet via its S1/0 interface and to a local area network (LAN) host via its GE0/0 interface. The LAN network segment is 10.0.0.0/8. There is an FTP server on the public network with the address 202.102.2.1. The IP address and routing have been configured, and the LAN host can access the Internet and the FTP server normally.
Add a new configuration to the router:
ACL Advanced 3000
rule 0 deny tcp source 10.1.1.1 0 source-port eq ftp destination 202.102.2.1 0
What intentions can this ACL achieve by applying it to the inbound and outbound directions of the GE0/0 interface?

A.Only block FTP data connections from the host with source address 10.1.1.1 to the destination host 202.102.2.1 on port 20 (TCP 20).
B.Prohibit the host with source address 10.1.1.1 from initiating an FTP connection to the destination host 202.102.2.1.
C.Only block FTP control connections from the host with source address 10.1.1.1 to the destination host 202.102.2.1 on port 21 (TCP 21).
D.There are no restrictions on FTP connections initiated from 10.1.1.1 to 202.102.2.1.

Question No : 10
One of the customer's MSR routers is connected to the Internet via the WAN interface S1/0; and to the office network via the LAN interface GE0/0. Currently, office network users can access the Internet normally.
Add the following ACL configuration to the router:
ACL Advanced 3000
rule 0 deny icmp
rule 5 permit tcp destination-port eq 20
interface GigabitEthernet0/0
packet-filter 3000 inbound
packet-filter 3000 outbound
Which of the following is correct?

A.ICMP packets sent to the internet by office network users are blocked by this router.
B.FTP traffic initiated by office network users to the internet is allowed to pass through this router, while all other packets are blocked from passing through this router.
C.FTP traffic initiated by office network users and destined for this router can pass through normally.
D.Telnet packets initiated by office network users and destined for router ge0/0 can pass through normally.

Question No : 12
A default route a is configured on an MSR router running OSPF with a next-hop address of 100.1.1.1; at the same time, the router learns a default route b with the same next-hop address of 100.1.1.1 from its neighboring router via OSPF.
This router uses the default priority and cost values for all routing protocols, which of the following is correct?

A.The router's routing table contains only route 'a' because route 'a' has a cost of 0.
B.The router's routing table will only contain route b, because dynamic routing takes precedence.
C.The router's routing table only contains route a because route a has a higher priority.
D.Both routes a and b will be written into the routing table because they originate from different sources and do not conflict with each other.

正解:

Question No : 13
