You are designing a wireless LAN with the following components:
High-density indoor access point deployment
2.4-GHz and 5-GHz radios
802.11a, 802.11g, and 802.11n mode wireless LAN clients
Site survey results show negligible foreign WiFi and non-WiFi interference. What is the best
method to decrease duty cycle (radio frequency utilization) and increase overall wireless LAN
client performance for this design?

You are designing an optical network. Your goal is to ensure that your design contains the highest
degree of resiliency. In which two ways will you leverage a wavelength-switched optical network
solution in your network design? (Choose two.)

You are the SAN designer for the ABC Company. Due to budget constraints, there is increased
pressure by management to further optimize server utilization by implementing virtualization
technologies on all servers and increase virtual machines density. Faced with some SAN
challenges, the server team requests your help in the design and implementation of the SAN in the
new virtualized environment.
In which two ways can NPIV be used in your proposed design? (Choose two.)

You are designing a network for a branch office. In order to improve convergence time, you are
required to use the BFD feature. Which four routing protocols can you use to facilitate this?
(Choose four.)

When developing an MVPN design, which performance and scalability consideration must be
taken into account?

In order to meet your service level agreement, your network designer created a design solution
that includes interface dampening. In which two ways will interface dampening benefit your overall
network design? (Choose two.)

A company wants to use SSM as the multicast routing protocol inside its network. Some of its
multicast applications do not support IGMPv3. In which two ways can the mapping be done when
these applications send IGMPv2 join messages? (Choose two.)

A company plans to use BFD between its routers to detect a connectivity problem inside the
switched network. An IPS is transparently installed between the switches. Which packets should
the IPS forward for BFD to work under all circumstances?

What is a design aspect regarding multicast transport for MPLS Layer 3 VPNs using the Rosen
Draft implementation?

A network designer wants to improve a company network design due to multiple network crashes.
Which technology would allow for the restore of a network connection without informing the Layer
3 protocol?
