You are designing a network solution to connect a primary data center to a disaster recovery site. The applications hosted on
the site will be mainly web and email servers that are provided through a virtualized environment. A third data center facility
may also be added in the next six months. Which connectivity type is appropriate for this design?
A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A
customer wants to connect one site with one box redundant to the Resilient Ethernet Protocol ring at two different service
provider locations. How can this be done without producing any Layer 2 loops within the network design?
When creating a network design, which one of these options provides for basic Layer 2 client isolation to prevent broadcast
Which option is a critical mechanism to optimize convergence speed when using MPLS FRR?
Refer to the exhibit. The two Ethernet switches are in close proximity to each other. Assuming that the IGP timers have
already been tuned for fast convergence, which additional change provides for the fastest network convergence time?
You have created a network design that has two point-to-point Metro Ethernet circuits extending a single production VLAN
between two data centers. Under normal circumstances, one circuit will carry traffic and spanning tree will block the other. If
the company wants you to make use of both circuits to carry production traffic, which two technologies and features will you
investigate to integrate into your network design? (Choose two.)
Refer to the exhibit.
A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2.
In which two of these ways can you design this solution?
Refer to the exhibit. This smart city has decided to deploy a converged network for video surveillance and applications for
utility services. These new applications are delay-sensitive and require strict convergence times of less than 50 milliseconds.
The network is expected to have up to 50 intermediate distribution frames per ring. Which protocol provides less than 50
Refer to the exhibit. As the new network designer for a manufacturing company, you are designing this resilient Ethernet ring
for the plant Ethernet network that is connected to the core, which does not use STP. Both edge ports are on the same
switch in a ring segment. There is connectivity between the edge ports throughout the segment, so you create a redundant
connection between any two switches in the ring. Which four options are characteristics of this design? (Choose four.)
B C E F
REP segments have thefollowing characteristics:
If all ports in a segment are operational, one port (referred to as the alternate port) is in the blocked state for each VLAN. If
VLAN load balancing is configured, two ports in the segment control the blocked state of VLANs.
If one or more ports in a segment is not operational, and cause a link failure, all ports forward traffic on all VLANs to
In case of a link failure, alternate ports are unblocked as quickly as possible. When the failed link is up, a logically blocked
portper VLAN is selected with minimal disruption to the network.

What are two design advantages to using virtual port channel? (Choose two.)
In a network design using carrier Ethernet, which three mechanisms can be used to improve Layer 2 down detection and
thereby reduce routing convergence time? (Choose three.)

Which option describes a design benefit of root guard?
What is a correct design consideration of IPv6 MLD snooping?
A mobile network operator is designing an NGN backhaul and plans to migrate their legacy SDH and SONET-based
transport network. The NGN network must achieve similar failover and failback times as the legacy network (50
milliseconds). Which method does allow for similar failover and failback times on the new packet-based network?
