What is a characteristic of a secure cloud architecture model?

A. limited access to job function

C. multi-factor authentication

D. software-defined network segmentation

An engineer is designing the QoS strategy for Company XYZ. Based on initial analysis, a lot of scavenger type of traffic is traversing the network's 20Mb Internet link toward the service provider. The new design must use a QoS technique that limits scavenger traffic to 2 Mbps, which helps avoid oversubscription of the link during times of congestion. Which QoS technique can be used to facilitate this requirement?

A. class-based traffic policing

B. LLQ

C. CBWFQ

D. class-based traffic shaping

You have been tasked with designing a data center interconnect as part of business continuity You want to use FCoE over this DCI to support synchronous replication. Which two technologies allow for FCoE via lossless Ethernet or data center bridging? (Choose two.)

A. DWDM

B. EoMPLS

C. SONET/SDH

D. Multichassis EtherChannel over Pseudowire

E. VPLS

Which two types of planning approaches are used to develop business-driven network designs and to facilitate the design decisions? (Choose two)

A. cost optimization approach

B. strategic planning approach

C. modular approach

D. tactical planning approach

E. business optimization approach

Which two aspects are considered when designing a dual hub dual DMVPN cloud topology? (Choose two )

A. will only work with single-tier headend architecture

B. hub sites must connect to both DMVPN clouds

C. recommended for high availability

D. spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly

E. requires all sites to have dual Internet connections

A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed Which two of these actions would reduce that delay? (Choose two.)

A. Increase network stability.

B. Reduce the time for the network to reconverge.

C. Increase the notification of interface flaps.

D. Enable lower data link layer recovery systems to have an opportunity to restore the interface

A. BPDU guard on access ports

B. BPDU guard on the aggregation switch downlinks toward access switches

C. root guard on the aggregation switch downlinks toward access switches

D. root guard on access ports

E. edge port on access ports

F. access switch pairs explicitly determined to be root and backup root bridges
