Cisco Designing Cisco Enterprise Networks 認定 300-420 試験問題 (Q161-Q166):

質問 # 161
Refer to the exhibit.

Refer to the exhibit. An architect is designing a BGP solution to connect a remote branch to a service provider. There are several prefixes within the branch that the company does not want to be advertised to the internet. Which solution should the architect use to accomplish this?

正解：B


質問 # 162
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.

正解：

解説：

Explanation

In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.


質問 # 163
Refer to the exhibit. An architect must design an IP addressing scheme for a multisite network connected via a WAN transit. The campus site must accommodate 12,000 devices and the branch sites must accommodate 1,000 devices. Which address scheme optimizes network device resources, contains convergence events to the different blocks of the network, and ensures future growth of the network?

正解：C


質問 # 164
What is a challenge of the SaaS model?

正解：D

解説：
A major SaaS challenge is the lack of direct application and infrastructure control. With Software as a Service, the provider operates the application stack, platform, upgrades, and supporting infrastructure. The customer benefits from reduced maintenance burden and lower initial deployment cost, but gives up much of the direct control normally available with on-premises applications. This affects troubleshooting, change windows, performance visibility, customization, data residency controls, and integration with existing enterprise systems. Higher initial costs are usually not a SaaS characteristic; SaaS commonly shifts spending toward subscription operating expense. Client computer upgrades are not normally required in the same way as thick-client enterprise software. Data and application integration can be complex, but the option that best captures the core architectural challenge is reduced control over the application and infrastructure. Network architects must account for this by designing secure direct internet access, cloud monitoring, identity integration, and reliable paths to SaaS providers. Reference topics: SaaS architecture, cloud application control, enterprise cloud access, operational visibility, SD-WAN SaaS design.


質問 # 165
Refer to the exhibit.

EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

正解：C

解説：
The EIGRP stub routing feature will prevent the remote device from advertising core routes back to the distribution devices. Routes learned by the remote device from Distribution 1 will not be advertised to Distribution 2. Therefore, Distribution 2 will not use the remote device as a transit for traffic destined to the network core https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_eigrp/configuration/15-mt/ire-15-mt-book/ire-eigrp-stub-rtg.html
