NEW QUESTION # 246
Refer to the exhibit.
As part of a redesign project, you must predict multicast behavior What happens to the multicast traffic received on the shared tree (*,G), if it is received on the LHR interface indicated*?
- A. It is dropped due to an unsuccessful RPk8t8ck against the multicast receiver.
- B. It is dropped due to an unsuccessful RPF check against the multicast source
- C. It is switched due to a successful RPF check against the routing table
- D. It is switched give that no RPF check is performed
Answer: B
Explanation:
https://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/16450-mcastguide0.html When a multicast packet arrives on an interface, the RPF process checks to ensure that this incoming interface is the outgoing interface used by unicast routing in order to reach the source of the multicast packet. This RPF check process prevents loops. Multicast routing does not forward a packet unless the source of the packet passes a RPF check. Once a packet passes this RPF check, multicast routing forwards the packet based only upon the destination address.
NEW QUESTION # 247
An enterprise has identified these causes for inefficient CAPEX spending:
- CAPEX planning is driven by technology and not by business
objectives.
- The CAPEX planning team lacks the data it needs to perform due
diligence tasks.
- The organizational structure lacks sufficient accountability and
incentives.
Which corporate cultural change contributes to improving the effectiveness of CAPEX spending?
- A. Build a financial control function that delivers high-quality reports on operational expenses for business insight and financial reporting.
- B. Marketing and product management divisions must reduce their CAPEX budgets significantly to drive the change.

NEW QUESTION # 248
A network uses an SDN architecture with switches and a centralized controller. What should be on the switches but not on the controller?
- A. data plane functions
- B. a northbound interface
- C. control plane functions
- D. a southbound interface
Answer: A
Explanation:
In a Software-Defined Networking (SDN) architecture:
Switches:
Primarily handle data plane functions: forwarding packets based on rules received from the controller.
They do not make routing or policy decisions on their own.
Controller:
Handles control plane functions: determining how traffic should flow.
Communicates with switches using a southbound interface (e.g., OpenFlow).
Offers a northbound interface for applications or orchestration tools.
NEW QUESTION # 249

- A. quality assessment
- B. policy management
- C. risk monitoring
- D. data stewardship
Answer: B
Explanation:
A key use case of data governance is policy management, where organizations define and enforce rules about data access, usage, and handling. This ensures compliance, security, and privacy while enabling greater controlled access to data.

NEW QUESTION # 265
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. Only BFD control packets are sent from forwarding engines along the Layer 2 path to perform detection
- B. BFD control packets are sent at a slower pace because the echo function is enabled
- C. BFD sessions at either end actively participate in the forwarding of echo packets
- D. BFD echo packets are sent from forwarding engines along the Layer 2 path to perform detection
- E. BFD control packets are sent at a higher pace because the echo function is enabled
Answer: C,D
Explanation:
# 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.
NEW QUESTION # 266
A green data center is being deployed and a design requirement is to be able to readily scale server virtualization. Which IETF standard technology can provide this requirement?
- A. data center bridging
- B. unified fabric
- C. Transparent Interconnection of Lots of Links
- D. fabric path
Answer: C
Explanation:
Transparent Interconnection of Lots of Links (TRILL) is an IETF standard specifically designed to improve scalability, convergence, and loop prevention in data center environments while supporting virtualization at scale. TRILL replaces traditional Spanning Tree Protocol (STP) with a shortest path forwarding protocol, combining the benefits of routing with the simplicity of bridging.
TRILL uses IS-IS as its control plane protocol to calculate optimal paths dynamically, enabling better bandwidth utilization and faster failover-critical for server virtualization that demands highly available, resilient, and scalable Layer 2 networks.
Why other options are incorrect:
* A. Data Center Bridging (DCB) is a set of enhancements for Ethernet but doesn't directly address virtualization scaling.
* B. Unified Fabric combines storage and data traffic but is not IETF standardized and focuses on cabling consolidation.
* D. FabricPath is Cisco proprietary, not IETF standard.
