A switched network is being deployed on a factory floor. 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.Design the network to include UDLD to detect unidirectional links and take them out of service
• B.Design the network to include EtherChannel bundles to prevent a single-link failure from taking down a switch interconnection point
• C.Design the network to include backbone fast on all devices to accelerate failure convergence times
• D.Design the network to include loop guard to prevent a loop in the switched network when a link has too much interference

Currently a service provider provides IPv4 traceroute services between MPLS PE routers.
The provider wants to implement IPv6 with MPLS 6PE/6VPE and then provide parallel IPv6 traceroute services between MPLS PE routers. Which two design solutions provide this service? (Choose two.)

• A.The PE routers must support full IPv6.
• B.The P routers must support ICMPv6.
• C.The P routers must support full IPv6.
• D.The PE routers must support ICMPv6.

A service provider hires you to design its new managed CE offering to meet these requirements
* The CEs cannot run a routing protocol with the PE
* Provide the ability for equal or unequal ingress load balancing in dual-homed CE scenarios.
* Provide support for IPv6 customer routes
* Scale up to 250.000 CE devices per customer.
* Provide low operational management to scale customer growth.
* Utilize low-end (inexpensive) routing platforms for CE functionality.
Which tunneling technology do you recommend?

• A.LISP
• B.FlexVPN
• C.DMVPN
• D.point-to-point GRE

Which two options are considered risks or concerns when both the Internet and VPN service functions are on the same PE router? (Choose two.)

• A.Customer performance can be affected by VPN traffic if Internet-based traffic is not prioritized on the P
• B.MP-BGP prefixes increase routers' global routing tables, which affects network convergence.
• C.BGP cannot simultaneously run on the PE router that runs MPLS.
• D.Internet-based attacks can affect VPN customers.
• E.Failure on the PE router affects both VPN and Internet services.

Refer to the exhibit. The service provider ACME Internet just added a 100Gbps peering in Paris to use as the default for inbound traffic from Very Big ISP. Which routing policy achieves the desired outcome?

• A.Apply an export policy that only permits a default route in Brussels and Zurich
• B.Apply an export policy in New York and Tokyo that adds a Weight attribute to routes sent to Very Big ISP via Paris
• C.Apply an export policy in Pans by applying a MED or Community attribute with a preference M Very Big ISP ads upon
• D.Use traffic engineering by injecting a preferred LocalPref attribute to routes advertised to Very Big ISP in Paris
