NEW QUESTION # 40
What type of topology does the ACI fabric use?
- A. Flat
- B. Tree
- C. Hierarchical
- D. Spine Leaf
Answer: D
Explanation:
* Review ACI Fabric Topology: The ACI fabric topology is based on a spine-leaf architecture, which is a scalable, two-layer network topology composed of spine switches and leaf switches1.
* Understand Spine-Leaf Benefits: This topology provides high-bandwidth connectivity between leaf switches and spine switches, allowing for efficient data flow across the network1.
* Recognize ACI Fabric Design: In an ACI fabric, each leaf switch connects to every spine switch, creating a non-blocking, high-throughput network that supports east-west traffic patterns typical in modern data centers1.
* Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with Cisco's guidelines on ACI fabric, which specify the spine-leaf topology as the standard for ACI deployments1.
NEW QUESTION # 41
A customer site has a VM in the VxBlock dedicated to a multicast application. The network monitoring team observes heavy network utilization each time the video streaming isrequested.
What should be enabled to address this issue?
- A. VTP
- B. LACP
- C. IGMP
- D. vPC
Answer: C
Explanation:
* Identify the Issue: Heavy network utilization during video streaming indicates that multicast traffic is not being efficiently managed1.
* Understand Multicast Traffic: Multicast applications use a single stream of data to deliver content to multiple recipients, which can cause network congestion if not handled properly1.
* Recognize IGMP's Role: Internet Group Management Protocol (IGMP) is used to manage multicast group memberships and is essential for optimizing multicast traffic on a network1.
* Implement IGMP: Enabling IGMP allows the network to efficiently distribute multicast traffic only to hosts that have explicitly requested it, reducing unnecessary network load1.

NEW QUESTION # 49 
Refer to the exhibit.
A cable with the following label was connected to the wrong equipment type:
* M91A-01:01 U61A-01:09
Based on the exhibit, what is the target equipment type?
- A. Nexus 9xxx, Slot A, Port1
- B. MDS 9xxx, Slot 1, Port 1
- C. UCS 6xxx FI, Uplink A, Slot 1, port 9
- D. UCS 5108 Chasses A, Slot 1, Port 9
Answer: B
Explanation:
The label on the cable indicates two parts: "M91A-01:01" and "U61A-01:09". The first part of the label
"M91A" refers to a specific type of equipment as per the exhibit. According to the exhibit, "M9" corresponds to "MDS 9xxx", which is a Cisco Multilayer Director Switch. The second part of the label, "U61A", does not directly match any category in the provided list; however, it seems to be an internal reference that could be related to user-specific configurations or locations.
Since we are looking for the target equipment type and not where it was mistakenly connected, we focus on the first part of the cable label. The numbers following "M91A" indicate slot and port information. Therefore, based on this labeling system and referring to the exhibit provided, which lists various EMC and Cisco equipment types along with their corresponding codes (like AP for APIC Appliance or CN for Cust. Network), we can deduce that "M91A" stands for "MDS 9xxx". The subsequent numbers "-01:01" suggest Slot 1, Port 1.
NEW QUESTION # 50
A System Engineer is validating system cabling for a VxBlock 1000. They find that some ports on Fabric Interconnects 1A are not connected.
Which connections are missing?
- A. Network uplinks to the customer network

Answer: C
Explanation:
* Review the VxBlock 1000 documentation: The System Engineer should review the VxBlock 1000 documentation to understand the standard cabling configuration for Fabric Interconnects1.
* Identify the role of Fabric Interconnects 1A: Fabric Interconnects serve as the nerve center for data and storage networking in the VxBlock 1000.They manage the connectivity between the compute, storage, and networks1.
* Determine the standard connection setup: Typically, Fabric Interconnects 1A would have server uplinks connected to the C-Series servers to manage data traffic between servers and the rest of the network2.
* Validate against the deployment checklist: The System Engineer should validate the cabling against the deployment checklist provided in the VxBlock Deploy Achievement document to ensure all connections are correctly made1.
