NEW QUESTION # 19
A VxBlock 1000 system is being deployed at a customer site. The system is equipped with a Nexus 93180YC aggregation switch to support routing features. A Juniper switch is used at the customer site as the core switch. The customer intends to run a dynamic routing protocol between the Nexus and Juniper switches.
Which routing protocol is recommended?
- A. OSPF
- B. EIGRP
- C. IGRP
- D. IGMP
Answer: A
Explanation:
* Review the VxBlock and Nexus Documentation: The VxBlock 1000 system documentation and the Nexus 93180YC switch documentation should be reviewed to understand the supported routing protocols1.
* Consider the Juniper Switch Capabilities: Since the customer is using a Juniper switch as the core switch, it's important to consider the routing protocols supported by Juniper switches.Juniper switches support a variety of routing protocols, including OSPF2.
* Evaluate Routing Protocol Options: EIGRP is typically Cisco proprietary and not supported on Juniper devices. IGMP is not a routing protocol but a multicast management protocol.IGRP is an older Cisco proprietary routing protocol and is less commonly used today2.
* Recommend OSPF: OSPF (Open Shortest Path First) is a widely supported, robust, and scalable dynamic routing protocol that is suitable for diverse environments, including mixed vendor setups like Cisco's Nexus and Juniper switches2.
* Validate with Best Practices: Best practices and recommendations from both Cisco and Juniper suggest using OSPF for dynamic routing between devices from different vendors2.

NEW QUESTION # 23 
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. UCS 6xxx FI, Uplink A, Slot 1, port 9
- B. Nexus 9xxx, Slot A, Port1
- C. MDS 9xxx, Slot 1, Port 1
- D. UCS 5108 Chasses A, Slot 1, Port 9
Answer: C
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 # 24
How are policies applied within an ACI fabric?
- A. Between two or more EPGs; all EPGs can be either unidirectional or bidirectional
- B. Between only two EPGs; both EPGs can be either unidirectional or bidirectional
- C. Between only two EPGs; both EPGs must be unidirectional
- D. Between two or more EPGs; all EPGs must be bidirectional
Answer: A
Explanation:
* Understand ACI Fabric: ACI fabric policies are applied to manage and control the network traffic within the fabric1.
* Identify Policy Application: Policies in ACI are applied between Endpoint Groups (EPGs), which are collections of network endpoints with common policy requirements1.
* Recognize Policy Direction: These policies can be applied in a unidirectional or bidirectional manner, providing flexibility in controlling the flow of traffic between EPGs1.
* Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with Cisco's guidelines on ACI fabric policies, which state that policies can be applied between two or more EPGs and can be either unidirectional or bidirectional1.
NEW QUESTION # 25

* manage network resources1.
* Identify the EPG: An Endpoint Group (EPG) is a collection of similar endpoints that represent an application tier or set of services within the ACI fabric1.
* Understand the Role of EPGs: EPGs group endpoints with identical networking policy requirements, allowing for the application of policies that regulate how such groups can interact with each other1.
* Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with Cisco's guidelines on ACI fabric, which define EPGs as collections of similar endpoints representing an application tier or set of services1.
NEW QUESTION # 26
Which NSX component communicates with the VTEP?
- A. Logical Router Control VM
- B. NSX Controller
- C. NSX Manager
- D. NSX Edge
Answer: B
Explanation:

NEW QUESTION # 33
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. vPC
- B. VTP
- C. IGMP
- D. LACP
Answer: C
Explanation:
