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.

A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?

A.

Updates that contain changes within the data are sent only when changes occur.

B.

Empty data subscriptions do not generate empty update notifications.

C.

Periodic updates include a full copy of the data that is subscribed to.

D.

The primary push update is sent immediately and cannot be delayed.

A company must automate a set of complex changes aligned with DR testing in the
network. These changes are specific, and the DR playbook will be adjusted in the future.
The playbook has diverse routing and switching assets in scope as well as multiple vendor
and hardware platforms. A developer will create a thin, web front-end microservice and
integrate with an Open daylight controller to push changes to the network. Which YANG
model should be used?

A.

Use a single native vendor YANG model to minimize development time

B.

Use an open YANG model to allow the reuse of code and standardize the
implementation across platforms

C.

Use multiple native vendor YANG models to provide code consistency.

D.

Develop an individualized YANG model to minimize development resources and time to
market.

An engineer must connect a new remote site to an existing OSPF network. The new site consists of two low-end routers, one for WAN, and one for LAN. There is no demand for traffic to pass through this area. Which area type does the engineer choose to provide minimal router resources utilization, while still allowing for full connectivity to the rest of the network?

A.

not so stubby

B.

totally not so stubby

C.

totally stubby area

D.

stubby area

Which two statements about VRRP object tracking are true? (Choose two)

A.

The priority of a VRRP device can change in accordance with the up or down
status of a VRRP object

B.

The VRRP interface priority must be manually configured by the administrator

C.

A VRRP group can track only one object at a time

D.

VRRP can track the status of interfaces and routes

E.

VRRP supports only interface tracking

A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic. Which technology must be chosen?

A.

IPsec

B.

GRE

C.

PPTP

D.

GRE over IPsec

Refer to the exhibit

A network engineer must improve the current IS-IS environment. The Catalyst switch is
equipped with dual supervisors. Each time a stateful switchover occurs, the network
experiences unnecessary route recomputation. Which solution addresses this issue if the
upstream router does not understand graceful restart messaging?

A.

Enable IS-IS remote LFA FRR on both devices.

B.

Enable NSR on the switch.

C.

Enable NSF on the switch.

D.

Configure ISIS aggressive timers on both devices.

An engineer must design a VPN solution for a company that has multiple branches
connecting to a main office. What are two advantages of using DMVPN instead of IPsec tunnels to accomplish this task? (Choose
two.)

A.

support for AES 256-bit encryption

B.

greater scalability

C.

support for anycast gateway

D.

lower traffic overhead

E.

dynamic spoke-to-spoke tunnels

A company is planning to open two new branches and allocate the
2a01:c30:16:7009::3800/118 IPv6 network for the region. Each branch should have the
capacity to accommodate maximum of 200 hosts. Which two networks should the company
use? (Choose two.)

A.

2a01:0c30:0016:7009::3a00/120

B.

2a01:0c30:0016:7009::3b00/121

C.

2a01:0c30:0016:7009::3a80/121

D.

2a01:0c30:0016:7009::3b00/120

E.

2a01:0c30:0016:7009::3c00/120

Refer to the exhibit. AS65533 and AS65530 are announcing a partial Internet routing table
as well as their IP subnets. An architect must create a design that ensures AS64512
become a transit AS. Which filtering solution must the architect choose?

A.

Maximum-prefix

B.

No-advertise

C.

Next-hop

D.

No Export
