How should you redesign this network running BGP to improve availability of the routers 1A and 1B at the core site?

A.

Deploy BGP PIC

B.

Use link bundles over multiple slots

C.

Enable graceful restart

D.

Create a multichassis system with the two routers

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

Drag the fast Reroute mechanism on the left and drop it onto the corresponding routing protocol on the right

A large enterprise network has two data centers and a WLAN edge with a large hub-and spoke network. The complete network is configured as a single OSPF area, and spoke routers are connected to unreliable WAN links. Which two changes should you make to deploy LSA on the spoke routers? (Choose two)

A.

Place spoke routers in stub areas

B.

Make the hub routers ABR

C.

Make the hub routers ASBR

D.

Place spoke routers in totally stubby areas

E.

Keep the spoke routers in normal areas

Classify the OSPF Fast Network Convergence technique by dragging the techniques on the left and dropping them into the corresponding categories on the right.

Which option describes a design benefit of root guard?

A.

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

B.

It prevents switch loops by detecting on one-way communications on the physical port.

C.

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

D.

It makes the port go immediately into the forwarding state after being connected.

E.

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

F.

It does not generate a spanning-tree topology change upon connecting and disconnecting a station on a port.

Which main IoT migration aspect should be reviewed for a manufacturing plant?

A.

Sensors

B.

Security

C.

Applications

D.

Wi-Fi Infrastructure

E.

You are designing an optical network. Your goal is to ensure that your design contains the highest degree of resiliency. In which two ways should you leverage a wavelength-switched optical network solution in your network design? (Choose two.)

A.

a wavelength-switched optical network guarantees restoration based strictly on the shortest path available

B.

a wavelength-switched optical network provides fault tolerance for single failures only

C.

a wavelength-switched optical network takes linear and nonlinear optical impairment calculation into account

D.

a wavelength-switched optical network assigns routing and wavelength information

E.

a wavelength-switched optical network eliminates the need for dispersion compensating units in a network

ARP spoofing

C.

ARP rate limiting

D.

Dynamic ARP Inspection

E.

Port security
