Which consideration is the most important for the network designer when considering IP routing?

A.    convergence
B.    scalability
C.    on-demand routing
D.    redistribution

Answer: A

You want to gather as much detail as possible during a network audit, to include data time stamping across a large number of interfaces, customized according to interface, with a minimal impact on the network devices themselves. Which tool would you use to meet these requirements?

A.    RMON
B.    SNMFV3
C.    NetFlow
D.    Cisco Discovery Protocol

Answer: C

DataQuirk is a web-based medical transcription company for exotic-animal veterinarians. The company recently added a third ISP for international business. They are organizing the enterprise network into a fully operational Enterprise Edge.
To which two modules will the three ISPs be directly related? (Choose two)

A.    PSTN
B.    E- Commerce
D.    Edge Distribution
E.    Internet Connectivity
F.    Remote Access VPN

Answer: BE

Which two of these practices are considered to be best practices when designing the access layer for the enterprise campus? (Choose two)

A.    Implement all of the services (QoS, security, STP, and so on) in the access layer, offloading the
work from the distribution and core layers.
B.    Always use a Spanning Tree Protocol; preferred is Rapid PVST+.
C.    Use automatic VLAN pruning to prune unused VLANs from trunked interface to avoid broadcast
D.    Avoid wasted processing by disabling STP where loops are not possible.
E.    Use VTP transparent mode to decrease the potential for operational error

Answer: BE

With deterministic Wireless LAN Controller redundancy design, the different options available to the designer have their own strengths. Which one of these statements is an example of such a strength?

A.    Dynamic load balancing, or salt-and-pepper access point design, avoids the potential impact of
oversubscription on aggregate network performance.
B.    N+N redundancy configuration allows logically grouping access points on controllers to minimize
intercontroller roaming events.
C.    N+N+1 redundancy configuration has the least impact to system management because all of the
controllers are collocated in an NOC or data center
D.    N+1 redundancy configuration uses Layer 3 intercontroller roaming, maintaining traffic on the same
subnet for more efficiency.

Answer: B

Which of these statements is true concerning the data center access layer design?

A.    The access layer in the data center is typically built at Layer 3, which allows for better shaping of
services across multiple servers.
B.    With Layer 2 access, the default gateway for the servers can be configured at the access or aggregation
C.    A dual-homing NIC requires a VLAN or trunk between the two access switches to support the dual IP
address on the two server links to two separate switches.
D.    The access layer is normally not required, as dual homing is standard from the servers to the
aggregation layer.

Answer: B

Which one of these statements should the designer keep in mind when considering the advanced routing features?

A.    one-way router redistribution avoids the requirement for state or default routes.
B.    Redistribution, summarization, and filtering are most often applied between the campus core and
enterprise edge.
C.    Filtering only occurs on the routing domain boundary using redistribution.
D.    Summarize routes at the core toward the distribution layer.
E.    The hierarchical flexibility of IPv6 addressing avoids the requirement for routing traffic reduction
using aggregation.

Answer: E

Which two statements about designing the Data Center Access layer are correct? (Choose two)

A.    Multiport NIC servers should each have their own IP address
B.    Layer 3 connectivity should never be used in the access layer
C.    Layer 2 connectivity is primarily implemented in the access layer
D.    Multiport NIC servers should never be used in the access layer
E.    Layer 2 clustering implementation requires servers to be Layer 2 adjacent

Answer: CE

Which IPv6 feature enables routing to distribute connection requests to the nearest content server?

A.    Link-local
B.    Site-local
C.    Anycast
D.    Multicast
E.    Global aggregatable

Answer: C

Refer to the exhibit. Model A is the recommended design for routing between Building Distribution switches and Campus Core switches. Which two statements describe the reasons? (Choose two)


A.    Model A uses timer-based non-deterministic convergence.
B.    Mode A uses timer-based, providing fast convergence to the remaining path.
C.    In Model A, a link or box failure does not require routing protocol convergence.
D.    In Model A, the Layer 3 redundant equal cost links support fast convergence.
