What are two benefits of designing an SD-WAN network fabric with direct Internet access implemented at every site? (Choose two.)

A. It decreases latency to applications hosted by public cloud service provider.

B. It decreases latency on Internet circuits.

C. It increases the speed of delivery of site deployments through zero-touch provisioning.

D. It increases the total available bandwidth on Internet circuits.

E. It alleviates network traffic on MPLS circuits.

A company is using OSPF between its HQ location and a branch office. HQ is assigned area 0 and the branch office is assigned area 1. The company purchases a second branch office, but due to circuit delays to HQ, it decides to connect the new branch office to the creating branch office as a temporary measure. The new branch office is assigned area 2. Which OSPF configuration enables all three locations to exchange routes?

A. The existing branch office must be configured as a stub area

B. A virtual link must be configured between the new branch office and HQ

C. A sham link must be configured between the new branch office and HQ

D. The new branch office must be configured as a stub area

Which method will filter routes between EIGRP neighbors within the same autonomous system?

A. distribute-list

B. policy-based routing

C. leak-map

D. route tagging

Refer to the exhibit. The distribution switches serve as the layer 3 boundary. HSRP preemption is enabled. When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?

x

A. split-horizon

B. summarization

C. down bit

D. route tags

An organization plans to deploy multicast across two different autonomous systems. Their solution must allow RPs to:

1.

discover active sources outside their domain

2.

use the underlying routing information for connectivity with other RPs

3.

announce sources joining the group

Which solution supports these requirements?

A. SSM

B. MSDP

C. PIM-DM

D. PIM-SM

Refer to the exhibit.

A customer has two eBGP peerings from a single CE router toward two service providers. The customer has hired an architect to design a solution to ensure certain traffic enters the customer's network through interface gig0/0.

Which solution must the architect include in the design?

A. Advertise a lower MED value toward the less preferred service provider.

B. Prepend additional AS on the AS path toward the preferred service provider.

C. Break aggregated routes into longer prefixes and advertise to the preferred service provider.

D. Set a higher local preference to the preferred service provider path.

Which is a benefit of a cloud-based SD-WAN deployment?

A. instant scale

B. security never an issue

C. might be required for compliance with industry standards

D. controller availability never an issue

E. agility of change dependent only on your own internal IT processes
