NEW QUESTION # 160
As part of workspace digitization, a large enterprise has migrated all their users to Desktop as a Sen/ice (DaaS), by hosting the backend system in their on-premises data center. Some of the branches have started to experience disconnections to the DaaS at periodic intervals, however, local users in the data center and head office do not experience this behavior. Which technology can be used to mitigate this issue?
Answer: A
Explanation:
Traffic Shaping does help with congestion and better bandwidth utilization over the WAN.
NEW QUESTION # 161
Which SDN architecture component is used by the application layer to communicate with the control plane layer to provide instructions about the resources required by applications?
Answer: D
NEW QUESTION # 162
What are two design constraints in a standard spine and leaf architecture? (Choose two.)
Answer: A,E
NEW QUESTION # 163
The administrator of a small branch office wants to implement the Layer 2 network without running STP. The office has some redundant paths. Which mechanism can the administrator use to allow redundancy without creating Layer 2 loops?
Answer: A
Explanation:
* B (Flex Links): Flex Links provide an alternative to Spanning Tree in simple Layer 2 designs. One link is active while the other is backup, preventing loops while maintaining redundancy without running STP.
Other options explained:
* A: vPC requires more advanced hardware and configuration.
* C: FabricPath is typically used in data centers, not small branches.
* D: 802.3ad is link aggregation, not redundant path management.
NEW QUESTION # 164
The controller has a global view of the network, and it can easily ensure that the network is in a consistent and optimal configuration. Which two statements describe a centralized SDN control path? (Choose two.)
Answer: C,D
Explanation:
* A (Scaling challenges for services):Centralized SDN controllers may experience scalability challenges for distributed services like DHCP and load balancing since these often require real-time responsiveness and distributed service locality.
* D (Latency in reactive handling):Centralized controllers may introduce additional latency during reactive PACKET_IN event handling as control decisions traverse the control plane before forwarding happens.
Other options explained:
* B: Centralized controllers still present failure domain risks; high-availability must be explicitly designed.
* C: Smart NICs operate primarily at the host level, often independently of centralized SDN controllers.
* E: Legacy equipment often lacks support for many SDN southbound APIs.
