Question 226

Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)

A.a new OSPF area for R1, R2, R3, and R4 connections, with R1, R2, R3, and R4 as ABRs

B.a new OSPF area for R3 and R4 connections, with R3 and R4 as ABRs

C.a new OSPF area for R1 and R2 connections, with R1 and R2 as ABRs

D.a new OSPF area for R1 and R2 connections, with R5 and R6 as ABRs

E.a new OSPF area for R3 and R4 connections, with R5 and R6 as ABRs

Question 227

Drag and drop the characteristics from the left onto the YANG models they describe on the right. Not all options are used.

Question 228

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

Question 229

An engineer must use YANG with an XML representation to configure a Cisco IOS XE switch with these specifications:
* IP address 10.10.10.10/27 configured on the interface GigabitEthernet2/1/0
* connectivity from a directly connected host 10.10.10.1/27
Which YANG data model set must the engineer choose?
A)

A.Option A

B.Option D

C.Option C

D.Option B

Question 230

Refer to the exhibit. A customer needs to apply QoS to the network management traffic passing through the GigabitEthernet0/2 interface. All eight queuing classes are in use, so the new requirement must be integrated into the existing policy. Which solution must the customer choose?

A.Mark traffic to DSCP CS5 and assign it to the SIGNALLING class. Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the SIGNALLING class.

B.Mark the traffic to DSCP CS4 and assign it to the SIGNALLING class. Then, prioritize traffic within the class.

C.Mark the traffic to DSCP CS6 and assign it to the ROUTING class Then, prioritize traffic within the class.

D.Mark the traffic to DSCP CS2 and assign it to the ROUTING class Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the ROUTING class
