A. CE devices that run OSPF set the DN bit toward the PE router

B. PE devices that run OSPF clear the DN bit toward the CE router

C. CE devices that run OSPF clear the DN bit toward the PE router

D. Creation of PE to PE OSPF sham link across the MPLS-created super backbone

E. PE routers verify OSPF domain IDs used by CE OSPF processes

F. PE devices that run OSPF set the DN bit toward the CE router

Which mechanism enables small, unmanaged switches to plug into ports of access switches without risking switch loops?

A. PortFast

B. UDLD

C. Root guard

D. BPDU guard

Which design benefit of Bridge Assurance is true?

A. It prevents switched traffic from traversing suboptimal paths on the network.

B. It prevents switched loops caused by unidirectional point-to-point, link condition on Rapid PVST+ and MST

C. It allows small unmanaged switches to be plugged into ports of access scenes without the risk of switch loops.

D. It suppresses a spanning-tree topology change upon connecting and disconnecting a station on a port.

B. Advertise Customer A subnets with different MED values to the two ISPs

C. Accept a default route from both ISPs

D. Make the CE connected to both ISPs route reflector

E. Accept the routes originated on both ISPs and their direct peers

Refer to the exhibit.

Service provider ACME Internet just added a 100 GB/s peering in Paris that it wants to use by default for outbound traffic to Big ISP. Which routing policy achieves the desired outcomes?

A. Use traffic engineering by injecting a preferred LOCAL_PREF attribute to routes advertised from Very Big ISP in Paris

B. Apply an import policy in New York that adds a Weight attribute to routes learned from Very Big ISP via Paris

C. Apply an export policy in Paris by applying a MED or community attribute with a preference that very Big ISP act upon

D. Apply an import policy hat filters longer prefixes than /24 in Brussels and zurich

You have been asked to design a wireless network solution that will implement context- aware services on an existing network that was initially deployed for data traffic only. Which two design principles would you follow to increase the location accuracy with the least possible impact on the current setup? (Choose two.)

A. Use directional antennas to provide better cell separation.

B. Add access points along the perimeter of the coverage area.

C. Install additional APs in monitor mode where the co-channel interference would otherwise be affected.

D. Increase the AP density to create an average inter-access point distance of less than 40 ft.| 12.2meters

E. Fine tune the access point's radio configuration to have a higher average transmission power to achieve better coverage.
