You have been asked to design a high -density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

A. Implement a four-channel design on 2.4 GHz to increase the number of available channels.

B. Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual- band clients are used.

C. Choose a high minimum data rate to reduce the dory cycle.

D. Enable 802.11n channel bonding both 2.4 GHz and 5 GHz to increase the aggregated cell throughput.

E. Increase the number of SSIDs to load-balance the client traffic.

Refer to the exhibit.

As part of a redesign project, you must predict multicast behavior. What is the resultant multicast traffic receiving on the shared tree( , G), if it is received on the LHR interface indicated?

A. It is dropped due to an unsuccessful RPF check against the multicast receiver

B. It is switched due to a successful RPF check against the routing table

C. It is switched given that no RPF check is performed

D. It is dropped due to an unsuccessful RPF check against the multicast source

Which two are IoT sensor-specific constraints? (Choose two)

A. Memory

B. Processing power

Company A is running a single-area OSPF, and Company B is running RIP as the IGP with no overlapping IP address spaces. Company A has just acquired Company B and both networks must be merged. Which three design components are recommended to guarantee connectivity and redundancy between the two networks? (Choose three.)

A. Enable mutual redistribution between OSPF and RIP on one border router.

B. Enable mutual redistribution between OSPF and RIP on Router A and Router B using route tags.

C. Increase the administrative distance to 130 for the OSPF external prefixes on Router A and Router B.

D. Implement an ACL on Router A and Router B to prevent OSPF external routes from being installed in the OSPF database.

E. Filter external routes on Router A and Router B based on route tags.

Which option is a design consideration when using routers in a distributed hardware architecture?

A. Routing information is stored in the RIB and the FIB makes forwarding decisions as programmed on the line card hardware

B. After a link failure occurs in the core, the RIB continues to forward the traffic while FIB convergence is in progress

C. BGP routes are stored in the RIB and IGP routes are stored in the FIB

D. IP routes are stored in the RIB and MPLS labels are stored in the FIB

An enterprise customer A with provider-independent address space is dual-homed to two ISP. Which two options , when combined, allow for customer A to efficiently achieve out- bond traffic load-balancing? ( Choose two)

A. Advertise Customer A subnets with a shorter AS path prepend to one of the ISPs than to the other

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

Which two reasons for implementing Cisco MPLS TE in a service provider MPLS backbone are valid? (Choose two.)

A. when Cisco MPLS TE is a prerequisite for implementing RSVP in the backbone

B. when Cisco MPLS TE is required to reroute traffic within Jess than 1 second in case of a link failure inside the backbone

C. when Cisco MPLS TE is required to create backup paths independently from the IGP

D. when Cisco MPLS TE can detect and react to neighbor failures faster than IGPs can

E. when Cisco MPLS TE is required to route different MPLS QoS service classes through different paths

Refer to the exhibit.
