Which connections are missing?
- A. Server uplinks to C-Series servers
- B. Network uplinks to Nexus switches
- C. Network uplinks to the customer network
- D. SAN uplinks to MDS switches
Answer: A
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.
NEW QUESTION # 24

NEW QUESTION # 31 
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. UCS 6xxx FI, Uplink A, Slot 1, port 9
- 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 # 32

NEW QUESTION # 33
Which logical entity in ACI allows for logical separation and reuse of IP address space within an ACI fabric?
- A. Tenant
- B. Context
- C. VLAN
- D. EPG
Answer: A
Explanation:
In ACI (Application Centric Infrastructure), the logical entity that allows for logical separation and reuse of IP address space within an ACI fabric is the Tenant. A Tenant represents a unit of isolation from a policy perspective and allows for the segmentation of the network into multiple virtual environments, each with its own policies and IP address spaces.
References:
* Cisco ACI documentation.
* Technical resources on ACI architecture and logical entities.
