質問 # 46
A standard virtual switch is deployed on an ESXi host. Four virtual machines are connected to the vSwitch, which has no uplink ports configured.
Which statement is accurate about network connectivity between the VMs?
- A. VMs can only communicate with one another if virtual guest tagging is used.
- B. VMs can communicate to outside networks if CDP is being used.
- C. All VMs can communicate, but only with one another.
- D. No communication is possible between VMs.
正解：C
解説：
* Understand vSwitch Functionality: A standard virtual switch (vSwitch) operates at the data link layer of the OSI model to connect virtual machines on the same ESXi host2.
* Recognize vSwitch without Uplinks: When a vSwitch has no uplink ports configured, it cannot communicate with external networks, but it can still facilitate communication between VMs connected to it1.
* Identify VM Communication: The VMs connected to the vSwitch without uplinks can communicate with each other, as the vSwitch can bridge traffic internally between VMs on the same VLAN2.
* Exclude External Communication: Without uplinks, the VMs cannot communicate with outside networks, regardless of whether Cisco Discovery Protocol (CDP) is used2.
質問 # 47
What order of steps is taken when using an NSX edge service gateway with proxy mode load balancing?
正解：
解説：
Explanation:
The order of steps taken when using an NSX edge service gateway with proxy mode load balancing is as follows:
* Client sends traffic to virtual IP address exposed by the load balancer.
* Load balancer performs address translation and sends traffic to server IP.
* Server replies by sending the traffic to the load balancer.
* Load balancer performs address translation and sends the traffic to client IP.
* The process begins with aclient initiating communicationby sending traffic to a virtual IP address, which is managed by the NSX edge service gateway functioning as a load balancer.
* Upon receiving the traffic, theload balancer translates this virtual IP addressinto one of the actual server IPs that it manages, effectively directing the client's request to an appropriate server in its pool.
* The selected server processes this request andresponds back, sending its reply to the load balancer rather than directly back to the client.
* Finally, once receiving this response from the server, the load balancertranslates it from its own internal server IP back into what appears as a response from the original virtual IP addressand forwards this response on to complete communication loop back at the client's end.
質問 # 48
Which NSX component communicates with the VTEP?
- A. Logical Router Control VM
- B. NSX Manager
- C. NSX Edge
- D. NSX Controller
正解：D
解説：
* Identify the VTEP's role: The VTEP, or VXLAN Tunnel Endpoint, is responsible for encapsulating and de-encapsulating the network traffic sent over the VXLAN1.
* Understand NSX Components: The NSX Controller is a key component of the VMware NSX network virtualization platform.It is responsible for the control plane, managing the state of virtual networks and overlay transport zones1.
* Communication with VTEP: The NSX Controller communicates with the VTEP to manage the overlay network and ensure that traffic is correctly routed and encapsulated across the network infrastructure1.
* Role of other NSX Components: While the NSX Edge provides routing services and the NSX Manager is the centralized management component, it is the NSX Controller that directly manages the state of the virtual network and communicates with the VTEPs1.
