QUESTION 184
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. |
Correct Answer: B
QUESTION 185
Which of the following is most accurate with respect to designing high availability within the Enterprise Campus network?
|
A. |
High availability at and between the Distribution and Access layers is as simple as redundant switches and redundant Layer 3 connections |
|
B. |
Non-deterministic traffic patterns require a highly available modular topology design |
|
C. |
Distribution layer high availability design includes redundant switches and Layer 3 equal-cost load sharing connections to the switched Access and routed Core layers, with a Layer 3 link between the Distribution switches to support summarization of routing information from the Distribution to the Core |
|
D. |
Default gateway redundancy allows for the failure of a redundant Distribution switch without affecting endpoint connectivity |
Correct Answer: D

B. |
Provide host-level redundancy by connecting each end device to 2 separate Access switches |
|
C. |
Offer default gateway redundancy by using dual connections from Access switches to redundant Distribution layer switches using a FHRP |
|
D. |
Include a link between two Access switches to support summarization of routing information from the Access to the Distribution layer |
Correct Answer: A
QUESTION 190
What are two characteristics of Cisco Global Site Selector? (Choose two.)
