Question: 14 

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 gre acl 

command under the incoming interface 

B. When routing the packet, matching a route whose outgoing interface is theGRE 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 

Answer: B 

Explanation: 

As for the correct answer, the process of routing a packet out a GRE tunnel interface triggers the GRE 

encapsulation action. As for the incorrect answers: There is no tunnel gre acl command. There is no 

IPsec tunnel interface. Finally, one answer refers to logic that would describe a router’s logic when 

determining whether to encapsulate a packet into an IPsec tunnel. 

Question: 15 


Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and 

IPsec tunnel, over the DSL connection, and into the core of an Enterprise network. The branch also 

allows local hosts to communicate directly with public sites in the Internet over this same DSL 

connection. Which of the following answers defines how the branch NAT config avoids performing NAT 

for the Enterprise directed traffic but does perform NAT for the Internet-directed traffic? 

A. By not enabling NAT on the IPsec tunnel interface 

B. By not enabling NAT on the GRE tunnel interface 

C. By configuring the NAT-referenced ACL to not permit the Enterprise traffic 

D. By asking the ISP to perform NAT in the cloud 

Answer: C 

Explanation: 

The NAT configuration acts only on packets permitted by a referenced ACL. As a result, the ACL can 

permit packets destined for the Internet, performing NAT on those packets. The ACL also denies packets 

going to the Enterprise, meaning that the router does not apply NAT to those packets. 

Question: 16 

Refer to the exhibit.

not coming up.

C. The crypto map is not applied to the correct interface.

Question: 19 



In the network diagram, Area 1 is defined as a stub area. Because redistribution is not allowed in the 

stub area, EIGRP routes cannot be propagated into the OSPF domain. How does defining area 1 as a notso-stubby 

area (NSSA) make it possible to inject EIGRP routes into the OSPF NSSA domain? 

A. by creating type 5 LSAs 

B. by creating type 7 LSAs 

C. by creating a link between the EIGRP domain and the RIP domain, and redistributing EIGRP into RIP
