질문 # 402
Refer to the exhibit.

Company XYZ must design a DMVPN tunnel between the three sites Chicago is going to act as the NHS and the company wants DMVPN to detect peer endpoint failures Which technology should be used m the design?

A. IP SLA
B. L2TPv3
C. VPLS
D. GRE

정답：A

질문 # 403
Drag and drop the optical technology design characteristics on the left to the correct optical technologies on the right. Not all options are used

정답：

설명：

질문 # 404
Two routers (R1 and R2) run OSPF and have registered with BFD in asynchronous mode with the echo function enabled. Which two actions occur with the echo function? (Choose two)

A. BFD control packets are sent at a slower pace because the echo function is enabled
B. Only BFD control packets are sent from forwarding engines along the Layer 2 path to perform detection
C. BFD sessions at either end actively participate in the forwarding of echo packets
D. BFD control packets are sent at a higher pace because the echo function is enabled
E. BFD echo packets are sent from forwarding engines along the Layer 2 path to perform detection

정답：C,E

설명：
# Explanation:
* B: BFD echo packets are looped back by the peer and sent through the data plane (forwarding engine) over the actual Layer 2 path. This ensures the link is not only up logically but physically functional.
* E: Both ends of the BFD session (R1 and R2) participate in sending/receiving and forwarding echo packets, validating bidirectional liveliness.
Other options:
* A: Echo packets are independent of control packets. Echo may offload failure detection to data plane but does not reduce control packet frequency.
* C: Control packet rate is not increased by echo function.
* D: Both control and echo packets play roles; it's not "only control packets" or "only echo packets" used in detection.

질문 # 405
What is the best approach to ensure both scalability and high availability for a cloud-based storage solution over the IP network?

A. Utilizing a Storage Area Network (SAN) with redundant controllers and paths for storage access.
B. Using a RAID (Redundant Array of Independent Disks) setup to provide data redundancy and improve performance.
C. Implementing Network Attached Storage (NAS) devices in a clustered configuration for load balancing.
D. Deploying a Content Delivery Network (CON) to cache and serve frequently accessed storage content.

정답：C

설명：
A clustered NAS solution provides scalability by allowing additional nodes to be added seamlessly and high availability through node redundancy and load balancing. This ensures continuous access to data while distributing workload efficiently over the IP network.

질문 # 406
Refer to the exhibit. An architect must design an enterprise WAN that connects the headquarters with 22 branch offices. The number of remote sites is expected to triple in the next three years.
The final solution must comply with these requirements:
- Only the loopback address of each of the enterprise CE X and Y
routers must be advertised to the interconnecting service provider
cloud network.
- The transport layer must carry the VPNv4 label and VPN payload over
the MP-BGP control plane.
- The transport layer must not be under service provider control.
Which enterprise WAN transport virtualization technique meets the requirements?

A. point-to-point GRE per VRF
B. MPLS over BGP over multipoint GRE
C. DMVPN per VRF
D. EIGRP Over the Top

정답：B
