NEW QUESTION # 12
What is needed to provide network isolation between vSwitch port groups?
- A. VMKernel port
- B. Separate VLAN IDs
- C. Uplink port
- D. Shared VLAN ID
Answer: B
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.

NEW QUESTION # 20 
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. UCS 5108 Chasses A, Slot 1, Port 9
- C. MDS 9xxx, Slot 1, Port 1
- D. Nexus 9xxx, Slot A, Port1
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.
