問題1

Exhibit:

Which routing protocol design will accomplish these goals?

A. Enable a full mesh of IBGP sessions between the routers in ISP B.

B. Configure each router in ISP B to peer with a par of route reflectors.

C. Redistribute the BGP routes learned from ISP A into the OSPF instance running in ISP B.

D. Configure static routes to ISP A on each router within ISP B.

正確答案: B

問題2

Which two statements about a customer's WAN connectivity are correct? (Choose two)

A. SD-WAN dynamically manages customer traffic across multiple WAN connections.

B. SD-WAN requires an IPsec tunnel to connect customer sites across the Internet.

C. Layer 2 managed services connects the customer's sites and the customer provides their own routing capability.

D. Layer 3 managed services automatically include Layer 2 provisioning to support the customer's needs.

正確答案: A,C

問題3

Your customer wants to use NorthStar to communicate with network devices and acquire the MPLS topology. Which protocol is recommended for this purpose?

A. BGP-LS

B. ISIS

C. OSPF

D. PIM-SSM

正確答案: A

問題4

Exhibit:

Within ISP E, R1 is load-balancing traffic destined to ISP D over the R1-R2-R5 and R1-R4-R5 paths. At some point, a link degradation event occurs in the network as shown in the exhibit. You want R1 to rapidly learn of the path failure.

A. Adjust the OSPF hello timer to a subsecond value between R4 and R5.

B. Adjust the OSPF hello timer to a subsecond value between R1 and R4.

C. Enable Bidirectional Forwarding Detection between R1 and R4.

D. Enable Bidirectional Forwarding Detection between R4 and R5.

正確答案: D

問題5

Your backbone network has a single dark fiber between two backbone sites within the same metro are a. Currency this link is being used as a point-to-point 100ObE link between the routers using gray optics. The link has been experiencing high utilization and you are asked to propose network design changes to increase capacity across this network segment.
Which statement is true in this scenario?

A. Enabling MPLS will increase capacity due to statistical multiplexing.

B. Gray optics can be used to increase capacity by enabling additional wavelengths.

C. Interfaces need to be reconfigured for 200GbE.

D. New optical interfaces will need to be added to the routers.

正確答案: D

問題6

Your customer is deploying a data center with redundant connections for WAN services through ISP-1 and ISP-2. Your customer has decided to deploy an active/passive Internet connection uplink model and pay-per-use for a passive connection associated with ISP-2. The customer wants to ensure limited use of the connection through ISP-2.
Which two actions would you perform to meet the objective? (Choose two )

A. Extend the AS Path length on the prefix advertised to ISP-2 to influence ingress traffic to enter through ISP-1.

B. Use Local Preference to direct northbound traffic flows out ISP-1

C. Use MED and Origin to direct northbound traffic flows out ISP-1

D. Extend the AS Path length on the prefix advertised to ISP-1 to influence ingress traffic to enter through ISP-1.

正確答案: A,B

問題7

- Have better traffic engineering for applications across an existing MPLS core.
- Support both IPv4 and IPv6 traffic
- Work with an MX Series core.
- Work with a North Star Controller
- Work with existing IGP (ISIS)
Which feature would you recommend be implemented in this solution?

A. opaque area LSAs

B. zero touch provisioning

C. CoS-based forwarding

D. segment routing
