第1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.Which of the following answers best describes the router‘s logic that tells the router, for a given packet, to apply GRE encapsulation to the packet?()
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
C. When routing the packet, matching a route whose outgoing interface is the IPsec tunnel interface
D. When permitted by an ACL that was referenced in the associated crypto map
第2题:
A.Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965.
B.Router1 will strip off the source IP address and replace it with the IP address 192.168.40.1.
C.Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320.
D. Router1 will strip off the destination IP address and replace it with the IP address of 192.168.40.1.
E.Router1 will forward the data packet out interface FastEthernet0/1.
F.Router1 will forward the data packet out interface FastEthernet0/2.

第4题:
What are two possible actions an IOS IPS can take if a packet in a session matches a signature?()
第5题:
A router receives an IPv6 packet which is 2000 bytes in length. The MTU of the outgoing interface is 1500 bytes. What action will the router take?()
第6题:
A traditional router is better suited than a firewall device for which function?()
第7题:
给了两段documentation里的描述,问这个时候发哪种类型的ICMP包。 The interface on which the packet comes into the router is the same interface on which the packet gets routed out. The subnet or network of the source IP address is on the same subnet or network of the next-hop IP address of the routed packet.
第8题:
A router receives a packet on interface 172.16.45.66/26. The source IP of the packet is 172.16.45.127/26 and the destination is 172.16.46.191/26.How will the router handle the packet?()
第9题:
Which action statement in a policy list causes a packet to be placed in an outgoing port queue without performing an IP route lookup?()
第10题:
第11题:
The destination is a host on another subnet, so the router will not forward the packet.
The destination is a host on the same subnet, so the router will forward the packet.
The destination is a broadcast address, so the router will not forward the packet.
The destination is a network address, so the router will forward the packet.
第12题:
It will fragment the packet at Layer 2.
It will fragment the packet at Layer 3.
It will drop the packet and send an ICMPv6 message packet too big back to the source.
It will drop the packet.
第13题:
A. The destination is a host on another subnet, so the router will not forward the packet.
B. The destination is a host on the same subnet, so the router will forward the packet.
C. The destination is a broadcast address, so the router will not forward the packet.
D. The destination is a network address, so the router will forward the packet.
第14题:
A.R1 will forward the packet out all interfaces.
B.R1 will drop this packet because this it is not a valid IP address.
C.As R1 forwards the frame containing this packet, Sw-A will add 192.168.1.255 to its MAC table.
D.R1 will encapsulate the packet in a frame with a destination MAC address of FF-FF-FF-FF-FF-FF
E.As R1 forwards the frame containing this packet, Sw-A will forward it to the device assigned the IP address of 192.168.1.255.
第15题:
How does an IPv6 router deal with a packet that is larger than the outgoing interface MTU?()
第16题:
An internet is a combination of networks connected by (1). When a datagram goes from a source to a (2), it will probably pass many (3) until it reaches the router attached to the destination network. A router receives a (4) from a network and passes it to another network. A router is usually attached to several networks. When it receives a packet, to which network should it pass the packet? The decision is based on optimization: Which of the available (5) is the optimum pathway? 空白(2)处应选择()
第17题:
By default if equal-cost paths exists for the same destination, which action will the router take?()
第18题:

第19题:
Which of the following describe router functions?()
第20题:
Firewall filters can perform which two actions?()
第21题:
A packet is evaluated against three user-defined terms within a firewall filter and no match isfound. What correctly describes the action the firewall filter will take for this packet?()
第22题:
Forward the packet.
Fragment the packet.
Drop the packet silently.
Drop the packet and send an ICMPv6 message.
第23题:
The filter will permit the packet and take no additional action.
The filter will reject the packet and send an ICMP message back to the sender.
The filter will discard the packet and take no additional action.
The filter will permit the packet and write a log entry to the firewall log.
