• A、The count parameter creates a counter that you can view with the show firewall command
• B、The count parameter allows the router to count the number of pings for logging purposes
• C、The count parameter allows the router to pause for 10000 seconds before sending out a ping
• D、The count parameter allows the router to send out 1000 pings and then stop

第7题：

Which three route filtering statements are true?（）

• A、After the router ospf 10  and passive - interface s0/0 commands have been issued , the s0/0 interface will not send any OSPF updates, but will receive routing updates on that interface
• B、When you use the passive - interface command with RIPv2, multicasts are sent out the specified interface
• C、After the router rip and passive -interface s0/0 commands have been issued, the s0/0 interface will not send any RIP updates, but will receive routing updates on that interface
• D、When you use the passive - interface command with EIGRP, hel lo messages are not sent out the specified interface
• E、After the router eigrp 10 and passive - interface s0/0 commands have been issued, the s0/0 interface will not send any EIGRP updates, but will receive routing updates on that interface
• F、When you use the passive - interface command with OSPF, hello messages are not sent out the specified interface

第8题：

• A、Avoid interface bandwidth saturation.
• B、Drop BGP routes when the routing-table becomes full.
• C、Remove unnecessary route attributes when not in use.
• D、Limit the effects of a flaping interface on route removal and readvertisement.

第9题：

Which two methods use IPsec to provide secure connectivity from the branch office to the headquarters office?（）

• A、DMVPN
• B、MPLS VPN

第15题：

Which two statements or sets of statements are true about the application of the qos pre-classify command？（）

• A、 If the classification policy is based upon the ToS byte， the qos pre-classify command is required because the ToS byte only appears in the inner IP header.
• B、 The ToS byte is copied to the outer header by default. Therefore， the qos pre-classify command is not necessary.
• C、 With GRE encapsulation， the qos pre-classify command is applied on the tunnel interface. This practice allows for different OoS configurations on each tunnel.
• D、 With GRE encapsulation， the qos pre-classify command is applied on the physical interface. This practice allows for different OoS configurations on each interface.
• E、 With IPsec encapsulation， the qos pre-classify command is applied on the physical interface. This practice allows for different OoS configurations on each interface.

第16题：

Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and IPsec tunnel, over the DSL connection, destined for an Enterprise network.

• A、When the packet received on the LAN interface is permitted by the ACL listed on the tunnel greacl command under the incoming interface
• B、When routing the packet, matching a route whose outgoing interface is the GRE tunnel interface
