Answer: C
Q102. Which statement is the most accurate regarding IPsec VPN design for an Enterprise Campus environment?
A. VPN device IP addressing must align with the existing Campus addressing scheme.
B. The choice of a hub-and-spoke or meshed topology ultimately depends on the number of remotes.
C. Sizing and selection of the IPsec VPN headend devices is most affected by the throughput bandwidth requirements for the remote offices and home worker
D. Scaling considerations such as headend configuration, routing protocol choice, and topology have the broadest impact on the design.
Answer: D

A. Separate the network into multiple areas for each new multiaccess segment.
B. Enable LSA throttling in the core to slow link state advertisement updates during times of network instability.
C. Ensure that the elected DR or BDR router can support high-volume convergence events.
D. Verify that fewer than 50 OSPF speakers are on the segment.
Answer: C
Q110. With respect to address summarization, which of the following statements concerning IPv4 and IPv6 is true?
A. The potential size of the IPv6 address blocks suggests that address summarization favors IPv6 over IPv4.
B. Role based addressing using wildcard masks to match multiple subnets is suitable for IPv4, but unsuitable for IPv6.
C. In order to summarize, the number of subnets in the IPv4 address block should be a power of 2 while the number of subnets in the IPv6 address block should be a power of 64.
D. WAN link addressing best supports summarization with a /126 subnet for IPv4 and a /31 for IPv6.
Answer: B
