You work as a network designer for a company that is replacing their Frame Relay WAN with an
MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in
their distribution routers, and they would like to advertise their access routers through the
MPLS network. Their service provider, however, only supports 1000 prefixes per VRF. Which
two design solutions can be applied to ensure that your access routers will be able to reach all
devices in your network? (Choose two.)

Voice trafficbetween two campus enterprise networks is growing. The network designers
decide to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in
orderto provide more bandwidth and diversity. The QoS profile will be the same on the new
10-Mb service due to the voice stability on the first Metro Ethernet link. When the second link
is added to the OSPF domain, which trafficdesign consideration would have the most impact
on the voice trafficwhen both links are active?

Youhave created a network design that has two point-to-point Metro Ethernet circuits
extending a single productionVLAN between two data centers. Under normal circumstances,
one circuit will carry trafficand spanning tree will block the other.If the company wants you to
make use of both circuits to carry productiontraffic,which two technologies and features will
you investigate to integrate into your network design? (Choose two.)

Refer to the exhibit.

Your company designed a network to allow server VLANs in a data center to span all accessswitches. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation
switches. In which three ways should the design of the STP domain be optimized for server and
application performance?(Choose three.)

A service provider has a Resilient Ethernet Protocol ring running as a metro backbone betweenits 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?

Refer to the exhibit.If IEEE 802.1w is in use for this network design, what are two locations where spanning-tree
root can be placed to ensure the least-disruptive Layer 2 failover for clients within VLANs 3 and
4? (Choose two.)

A switched network is being designed to support a manufacturing factory. Due to cost
constraints, fiber-based connectivity is not an option. Which design allows for a stable network
when there is a risk of interference from the manufacturing hardware in use on the factory
floor?

A network designer is redesigning an enterprise campus network to ensure that Ethernet
switches proactively attempt to reconnect after a fiber cut. In the design, they will have to
address areas where fiber cuts exist on campus from past troubleshooting, where a single fiber
is disconnected in the fiber pair, leading to looping. Which feature could be implemented in the
design to allow the Spanning Tree Protocol on the switches to be protected?

Refer to the exhibit.

You are designing a spanning-tree network for a small campus. Which two of these options
would result in a trouble-free spanning-tree network design? (Choose two.)

A network designer is working with a company to improve convergence at the Layer 2 control
plane and decides to use LACP.Which of these components does LACP use to create the system
ID?
