NEW QUESTION # 25
What is needed to provide network isolation between vSwitch port groups?
- A. Separate VLAN IDs
- B. VMKernel port
- C. Shared VLAN ID
- D. Uplink port
Answer: A
Explanation:
* Understand the role of VLANs: VLANs (Virtual Local Area Networks) are used to segment network traffic.They provide isolation between network segments at the data link layer (Layer 2) of the OSI model1.
* Identify the need for isolation: vSwitch port groups are used to segregate network traffic for different virtual machines or services.To ensure that each port group's traffic is isolated from the others, separate VLAN IDs are assigned1.
* Assign unique VLAN IDs: Each vSwitch port group should be assigned a unique VLAN ID to maintain network isolation.This prevents traffic from one port group from being accessible to another1.
* Configure the physical switch ports: The physical switch ports that the vSwitch is connected to must be configured to recognize the VLAN IDs used by the vSwitch port groups1.
* Validate the configuration: After configuring VLAN IDs, it's important to validate the configuration to ensure that the network isolation is functioning as intended1.

* Understand the Purpose: It summarizes the key components, features, and benefits of the solution, giving stakeholders a clear understanding of the project scope1.
* Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would include the Solution Abstract as part of the standard documentation provided to customers1.
NEW QUESTION # 27
A VxBlock 1000 UCS domain is being managed via Fabric Interconnect (FI) A as the cluster lead. The expansion team adds two new B-series servers to the domain. When attempting to vMotion from the existing blades to one of the new blades, the power to Fabric Interconnect A is disconnected.
What is the expected result?
- A. vMotion fails, but is automatically retried once the Fl comes back online
- B. vMotion completes successfully, but access to the vCenter will be lost
- C. vMotion fails because the Fl managing the session is powered off
- D. vMotion completes successfully despite the FI power failure
Answer: C
Explanation:
* Review VxBlock 1000 UCS Domain Management: The UCS domain is managed via Fabric Interconnect A, which acts as the cluster lead and is critical for operations1.
* Understand vMotion Process: vMotion is a VMware feature that allows for the live migration of virtual machines from one host to another without downtime1.
* Identify Impact of FI A Power Disconnection: If the power to Fabric Interconnect A is disconnected during a vMotion process, the vMotion session being managed by FI A will fail because it loses its management connection1.
* Recognize Automatic Retry Mechanism: Although vMotion fails when FI A is powered off, it is typically designed to retry the operation once the managing FI comes back online1.
* Reference Official Dell Documentation: The Official Dell VxBlock Deploy Achievement document
* would confirm that the expected result of such a scenario is the failure of the vMotion process due to the power disconnection of the managing Fabric Interconnect1.
NEW QUESTION # 28
What type of topology does the ACI fabric use?
- A. Spine Leaf
- B. Tree
- C. Flat

NEW QUESTION # 39
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. IGMP
- B. EIGRP
- C. IGRP
- D. OSPF
Answer: D
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.
