Which three sources does a network designer use to collect information for characterizing an existing network? (Choose three.)

A.    staff input
B.    visual inventory
C.    network audit
D.    traffic analysis
E.    server statistics

Answer: ACD

What is the primary consideration when choosing a routed network design over a traditional campus network design?

A.    Layer 3 service support at the network edge
B.    the routing protocol choice: open (OSPF) or proprietary (EIGRP)
C.    the routing abilities of the host devices
D.    the need to control the broadcast domains within the campus core

Answer: A

Which statement 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 sharing of services across multiple servers.
B.    With Layer 2 access, the default gateway for the servers can be configured at the access or aggregation layer.
C.    A dual-homing NIC requires a VLAN or trunk between the two access switches to support the dual IP addresses 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 statement is true concerning the data center distribution (aggregation) layer design?

A.    With Layer 3 at the aggregation layer, the physical loops in the topology must still be managed by STP.
B.    The boundary between Layer 2 and Layer 3 must reside in the multilayer switches, independent of any other devices.
C.    A mix of both Layer 2 and Layer 3 access is the most optimal.
D.    In a small data center, the aggregation layer can connect directly to the campus core, exchanging IP routes and MAC address tables.

Answer: C

When considering the three VoIP design models – single site, centralized multisite, and distributed multisite — which question below would help to eliminate one of the options?

A.    Will the switches be required to provide inline power?
B.    Will users need to make offsite calls, beyond the enterprise?
C.    Will users require applications such as voice mail and interactive voice response?
D.    Are there users whose only enterprise access is via a QoS-enabled WAN?

Answer: D

With deterministic Wireless LAN Controller redundancy design, the different options available to the designer have their own strengths. Which statement 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 colocated 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

When there is a need for immunity to EMI for connecting locations that are greater than 100 meters apart, which two solutions can be utilized? (Choose two.)

B.    aggregation
C.    Layer 3 access
D.    distribution

Answer: B

A data center is reaching its power and cooling capacity. What two virtualization technologies can address the problem by directly reducing the number of physical devices? (Choose two.)

D.    virtual routing and forwarding
E.    virtual port channels
F.    virtual LANs

Answer: BC

A.    floating static entry
B.    EIGRP variance
C.    bandwidth metric
D.    OSPF maximum paths
