質問 # 33
An NSX administrator would like to create an L2 segment with the following requirements:
* L2 domain should not exist on the physical switches.
* East/West communication must be maximized as much as possible.
Which type of segment must the administrator choose?
- A. Bridge
- B. Overlay
- C. VLAN
- D. Hybrid
正解：B
解説：
Explanation
An overlay segment is a layer 2 broadcast domain that is implemented as a logical construct in the NSX-T Data Center software. Overlay segments do not require any configuration on the physical switches, and they allow for optimal east/west communication between workloads on different ESXi hosts. Overlay segments use the Geneve protocol to encapsulate and decapsulate traffic between the hosts. Overlay segments are created and managed by the NSX Manager.

質問 # 35
A company Is deploying NSX micro-segmentation in their vSphere environment to secure a simple application composed of web. app, and database tiers.
The naming convention will be:
* WKS-WEB-SRV-XXX
* WKY-APP-SRR-XXX
* WKI-DB-SRR-XXX
What is the optimal way to group them to enforce security policies from NSX?
- A. Create an Ethernet based security policy.
- B. Use Edge as a firewall between tiers.
- C. Group all by means of tags membership.
- D. Do a service insertion to accomplish the task.
正解：C
解説：
The answer is C. Group all by means of tags membership.
Tags are metadata that can be applied to physical servers, virtual machines, logical ports, and logical segments in NSX. Tags can be used for dynamic security group membership, which allows for granular and flexible enforcement of security policies based on various criteria1 In the scenario, the company is deploying NSX micro-segmentation to secure a simple application composed of web, app, and database tiers. The naming convention will be:
WKS-WEB-SRV-XXX
WKY-APP-SRR-XXX
WKI-DB-SRR-XXX
The optimal way to group them to enforce security policies from NSX is to use tags membership. For example, the company can create three tags: Web, App, and DB, and assign them to the corresponding VMs based on their names. Then, the company can create three security groups: Web-SG, App-SG, and DB-SG, and use the tags as the membership criteria. Finally, the company can create and apply security policies to the security groups based on the desired rules and actions2 Using tags membership has several advantages over the other options:
It is more scalable and dynamic than using Edge as a firewall between tiers. Edge firewall is a centralized solution that can create bottlenecks and performance issues when handling large amounts of traffic3 It is more simple and efficient than doing a service insertion to accomplish the task. Service insertion is a feature that allows for integrating third-party services with NSX, such as antivirus or intrusion prevention systems. Service insertion is not necessary for basic micro-segmentation and can introduce additional complexity and overhead.
It is more flexible and granular than creating an Ethernet based security policy. Ethernet based security policy is a type of policy that uses MAC addresses as the source or destination criteria. Ethernet based security policy is limited by the scope of layer 2 domains and does not support logical constructs such as segments or groups.
To learn more about tags membership and how to use it for micro-segmentation in NSX, you can refer to the following resources:

The status should be "Enabled" if the integration is successful. The other options are either incorrect or not relevant.
質問 # 41
Which two of the following will be used for Ingress traffic on the Edge node supporting a Single Tier topology? (Choose two.)
- A. Downlink Interface for the Tier-0 OR
- B. Downlink Interface for the Tier-1 DR
- C. Tler-0 Uplink Interface H Tier-1 SR Router Port
- D. Inter-Tier Interface on the Tier-0 gateway
正解：C、D
解説：
Single Tier topology is a simplified NSX design that uses only one logical router (Tier-1) for both north-south and east-west traffic. The Tier-1 logical router has two components: a Distributed Router (DR) and a Services Router (SR). The DR performs distributed routing across all transport nodes, while the SR provides centralized services such as NAT, DHCP, VPN, etc. The SR is hosted on an Edge node that also hosts a Tier-0 gateway. The Tier-0 gateway is used for connecting to the physical network and providing dynamic routing protocols such as BGP or OSPF.
Ingress traffic on the Edge node supporting a Single Tier topology will use two interfaces: an Inter-Tier Interface on the Tier-0 gateway and a Tier-1 SR Router Port. The Inter-Tier Interface is a logical port that connects the Tier-0 gateway to the Tier-1 gateway. This interface enables routing between the two gateways and carries all the routing protocols and traffic. The Tier-1 SR Router Port is a logical port that connects the Tier-1 SR to the Tier-1 DR. This interface enables routing between the centralized and distributed components of the Tier-1 logical router.
質問 # 42
What are three NSX Manager rotes? (Choose three.)
- A. zookeepet
- B. policy
- C. manager
- D. cloud
- E. master
- F. controller
正解：B、C、F
解説：
Explanation
According to the VMware NSX 4.x Professional documents and tutorials, an NSX Manager is a standalone appliance that hosts the API services, the management plane, control plane, and policy management. The NSX Manager has three built-in roles: policy, manager, and controller2. The policy role handles the declarative configuration of the system and translates it into desired state for the manager role. The manager role receives and validates the configuration from the policy role and stores it in a distributed persistent database. The manager role also publishes the configuration to the central control plane. The controller role implements the central control plane that computes the network state based on the configuration and topology information3.
The other roles (master, cloud, and zookeeper) are not valid NSX Manager roles.

質問 # 44
What needs to be configured on a Tler-0 Gateway lo make NSX Edge Services available to a VM on a VLAN-backed logical switch?
- A. VLAN Uplink
- B. Loopback Router Port
- C. Downlink Interface
- D. Service Interface
正解：A
解説：
Explanation
To make NSX Edge Services available to a VM on a VLAN-backed logical switch, you need to configure a VLAN Uplink on the Tier-0 Gateway. A VLAN Uplink is a logical interface that connects the Tier-0 Gateway to the physical network and provides external connectivity for the NSX Edge Services1. A VLAN Uplink can be configured on the NSX Manager UI by selecting Networking > Tier-0 Gateways > Interfaces > Set > Add Interface1.

質問 # 45
Where in the NSX UI would an administrator set the time attribute for a time-based Gateway Firewall rule?
- A. The option to set time-based rule is a clock Icon in the rule.
- B. There Is no option in the NSX UI. It must be done via command line interface.
- C. The option to set time based rule is a field in the rule Itself.
- D. The option to set time-based rule is a clock Icon in the policy.
正解：D
解説：
Explanation
According to the VMware documentation1, the clock icon appears on the firewall policy section that you want to have a time window. By clicking the clock icon, you can create or select a time window that applies to all the rules in that policy section. The other options are incorrect because they either do not exist or are not related to the time-based rule feature. There is no option to set a time-based rule in the rule itself, as it is a policy-level setting. There is also an option to set a time-based rule in the NSX UI, so it does not require using the command line interface.
