A. R1 will have routes in its routing table that originate from R2 and R3.
B. R3 will have routes in its routing table that originate from R1 and R2.
C. R2 will have routes in its routing table that originate from R1 and R3.
D. R3 will be transit for traffic between R1 and R2.
E. R3 will not be transit for traffic between R1 and R2.
Answer: BE
Q2. Refer to the exhibit.
You are planning the design of an encrypted WAN. IP packets will be transferred over encrypted GRE tunnels between routers B and C. The packet size is limited to a maximum of 1500 bytes inside the WAN between routers B and C. If endpoint 1 tries to send 1500-byte IP packets to endpoint 2, in what three ways will the network design handle the fragmentation in three different possible network configurations? (Choose three.)
A. When router B fragments packets after the encryption, router C must reassemble these fragmented packets.
B. When router B fragments packets before the encryption, router C must reassemble these fragmented packets.
C. When router B fragments packets after the encryption, the endpoint 2 must reassemble these fragmented packets.
D. When router B fragments packets before the encryption, endpoint 2 must reassemble these fragmented packets.
E. When router A fragments packets, router C must reassemble these fragmented packets.
F. When router A fragments packets, endpoint 2 must reassemble these fragmented packets.
Answer: ADF
Q3. You are designing a Group Encrypted Transport virtual private network solution for an existing branch network. The existing network has the following characteristics:
. 50 remote sites (with an additional 30 remote sites expected over the next 3 years) . Connectivity between all sites is via Multiprotocol Label Switching Layer 3 virtual private network service from a single provider . Open Shortest Path First is the routing protocol used between provider edge and customer edge routers . The customer edge routers will become group members performing the encryption between sites
Which additional routing protocol would you use for the overlay routing between the group members?
A. Open Shortest Path First (with a different process ID)
B. Enhanced Interior Gateway Routing Protocol
C. No additional protocol is necessary.
D. External Border Gateway Protocol
E. Routing Information Protocol Version 2
F. Next Hop Resolution Protocol
Answer: C

B. PKI
C. UKI
D. password
Answer: AB
Q5. Refer to the exhibit.

Which of the following design solutions accomplishes these requirements?
A. Route summarization, with specific route leaking on hubs A and B
B. Route summarization, with GRE tunnel on hubs A and B
C. Implement PfR enhancements on hubs A and B.
D. Implement ODR for hub-to-spoke routing.
Answer: B
Q6. How should multiple OSPF areas be designed when deployed on a classic three-layer (core/distribution/access) network hierarchy?
A. The OSPF flooding domain boundary should be at the edge of the core layer.
B. The OSPF flooding domain boundary should be within the distribution layer.
C. OSPF should generally be deployed in a three-layer domain hierarchy to align with the physical three-layer hierarchy.
D. OSPF flooding domain boundaries should be placed with route aggregation in mind.
Answer: D
