Question 1

During evaluation of migrating current on premises infrastructure to add cloud-based infrastructure, a network

planning team must meet three core requirements as they make recommendations on which cloud strategy to

adopt going forward

• Technology is changing rapidly, therefore the enterprise must be open to adopting new ways of doing things,

and be ready to invest CapEx-funds in the next three years

• Network bandwidth capacity requirements are dynamic and are expected to change over the next year

• If new technologies are to be introduced, operational expenses must be kept at a minimum. Which cloud

strategy meets these requirements?

Options :

A : private

B : hybrid

C : public

D : multicloud

Answer: D

Question 2

Video traffic is being distributed across a large WAN network. The video source originates from different parts of the multicast domain at different times. Which multicast technology provides optimal path selection between the receiver and the source for this multicast traffic?

Options :

A : Source Specific Multicast

B : PIM sparse mode

C : Bidirectional PIM

D : Any Source Multicast

Answer: A

Question 3

Which option describes a design benefit of root guard?

Options :

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

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

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

D : It prevents switched traffic from traversing suboptimal paths on the network

E : It prevents switch loops by detecting one-way communications onthe physical port

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

Answer: B

Question 4

VPLS is implemented in a Layer 2 network with 2000 VLANs. What is the primary concern to ensure successful deployment of VPLS?

Options :

A : VLAN scalability

B : PE scalability

C : The underlying transport mechanism

D : Flooding is necessary to propagate MAC address reachability information

Answer: B

Question 5

Refer to the exhibit.

An engineer is designing the network for a multihomed customer running in AS 111 does not have any other

Ass connected to it. Which technology is more comprehensive to use in the design to make sure that the AS is

not being used as a transit AS?

Options :

A :

Configure the AS-set attribute to allow only routes from AS 111 to be propagated to the neighbor ASs.

B :

Use the local preference attribute to configure your AS as a non-transit'' AS.

C :

include an AS path access list to send routes to the neighboring ASs that only have AS 111 in the AS

path field.

D :

Include a prefix list to only receive routes from neighboring ASs.
