Question #11
Which field in a Tier-1 Gateway Firewall would be used to allow access for a collection of trustworthy web sites?
- A . Source
- B . Profiles -> Context Profiles
- C . Destination
- D . Profiles -> L7 Access Profile
Correct Answer: D
D
Explanation:
The field in a Tier-1 Gateway Firewall that would be used to allow access for a collection of trustworthy web sites is Profiles -> L7 Access Profile. This field allows the user to create a Layer 7 access profile that defines a list of allowed or blocked URLs based on categories, reputation, or custom entries1. The user can then apply the L7 access profile to a firewall rule to control the traffic based on the URL filtering criteria1. The other options are incorrect because they are not related to URL filtering. The Source field specifies the source IP address or group of the firewall rule1. The Destination field specifies the destination IP address or group of the firewall rule1. The Profiles -> Context Profiles field allows the user to create a context profile that defines a list of application signatures or attributes that can be used to identify and classify network traffic1.

Question #12
An administrator is configuring service insertion for Network Introspection.
Which two places can the Network Introspection be configured? (Choose two.)
- A . Host pNIC
- B . Partner SVM
- C . Tier-0 gateway
- D . Tier-1 gateway
- E . Edge Node
Correct Answer: AB
AB
Explanation:
Network Introspection is a service insertion feature that allows third-party network security services to monitor and analyze the traffic between virtual machines. Network Introspection can be configured on the host pNIC or on the partner SVM, depending on the type of service and the deployment model. The host pNIC configuration is used for services that require traffic redirection from the physical network to the service virtual machine. The partner SVM configuration is used for services that require traffic redirection from the virtual network to the service virtual machine. Network Introspection cannot be configured on the Tier-0 or Tier-1 gateways, as they are not part of the data plane where the service insertion occurs. Network Introspection also cannot be configured on the edge node, as it is a logical construct that hosts the Tier-0 and Tier-1 gateways.

Question #14
Which statement is true about an alarm in a Suppressed state?
- A . An alarm can be suppressed for a specific duration in seconds.
- B . An alarm can be suppressed for a specific duration in days.
- C . An alarm can be suppressed for a specific duration in minutes.
- D . An alarm can be suppressed for a specific duration in hours.
Correct Answer: D
D
Explanation:
An alarm can be suppressed for a specific duration in hours.
According to the VMware NSX documentation, an alarm can be in one of the following states: Open, Acknowledged, Suppressed, or Resolved12
An alarm in a Suppressed state means that the status reporting for this alarm has been disabled by the user for a user-specified duration12
When a user moves an alarm into a Suppressed state, they are prompted to specify the duration in hours. After the specified duration passes, the alarm state reverts to Open. However, if the system determines the condition has been corrected, the alarm state changes to Resolved13

Question #16
NSX improves the security of today’s modern workloads by preventing lateral movement, which feature of NSX can be used to achieve this?
- A . Network Segmentation
- B . Virtual Security Zones
- C . Edge Firewalling
- D . Dynamic Routing
Correct Answer: A
A
Explanation:
According to the web search results, network segmentation is a feature of NSX that improves the security of today’s modern workloads by preventing lateral movement. Lateral movement is a technique used by attackers to move from one compromised system to another within a network, exploiting vulnerabilities or credentials. Network segmentation prevents lateral movement by dividing a network into smaller segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot access other segments or resources.
NSX enables network segmentation by using micro-segmentation, which applies granular firewall rules at the virtual machine level, regardless of the physical network topology.

Question #17
In an NSX environment, an administrator is observing low throughput and congestion between the Tier-O Gateway and the upstream physical routers.
Which two actions could address low throughput and congestion? (Choose two.)
- A . Configure NAT on the Tier-0 gateway.
- B . Configure ECMP on the Tier-0 gateway.
- C . Deploy Large size Edge node/s.
- D . Add an additional vNIC to the NSX Edge node.
- E . Configure a Tier-1 gateway and connect it directly to the physical routers.
Correct Answer: BC
BC
Explanation:
ECMP (Equal Cost Multi-Path) is a routing protocol that increases the north and south communication bandwidth by adding an uplink to the tier-0 logical router and configure it for each Edge node in an NSX Edge cluster2. The ECMP routing paths are used to load balance traffic and provide fault tolerance for failed paths2. The tier-0 logical router must be in active-active mode for ECMP to be available2. A maximum of eight ECMP paths are supported2. Configuring ECMP on the tier-0 gateway can address low throughput and congestion by distributing the traffic among multiple paths and avoiding bottlenecks.
Deploying Large size Edge node/s can also address low throughput and congestion by providing more resources (memory, CPU, disk) for the Edge node to handle the network traffic. The NSX Edge VM system requirements vary depending on the appliance size, which affects the bandwidth, NAT/firewall, load balancer, and VPN capabilities of the Edge node1. A Large size Edge node has 32 GB memory, 8 vCPU, 200 GB disk space, and can support 2-10 Gbps bandwidth, L2-L4 features, and L7 load balancer1. An Extra Large size Edge node has 64 GB memory, 16 vCPU, 200 GB disk space, and can support more than 10 Gbps bandwidth, L2-L4 features, L7 load balancer, and VPN1. Deploying a larger size Edge node can improve the performance and capacity of the tier-0 gateway.

Question #18
What are the four types of role-based access control (RBAC) permissions? (Choose four.)
- A . Read
- B . None
- C . Auditor
- D . Full access
- E . Enterprise Admin
- F . Execute
- G . Network Admin
Correct Answer: ABDF
ABDF
Explanation:
The four types of role-based access control (RBAC) permissions are Read, None, Full access,
and Execute1. Read permission allows the user to view the configuration and status of the system. None permission denies any access to the system. Full access permission grants all permissions including Create, Read, Update, and Delete (CRUD). Execute permission includes Read and Update permissions1. Auditor, Enterprise Admin, and Network Admin are not types of permissions, but types of roles that have different sets of permissions. References: NSX Features
There are four types of permissions. Included in the list are the abbreviations for the permissions that are used in the Roles and Permissions and Roles and Permissions for Manager Mode tables. Full access (FA) – All permissions including Create, Read, Update, and Delete Execute (E) – Includes Read and Update Read (R) None
NSX-T Data Center has the following built-in roles. Role names in the UI can be different in the API.
In NSX-T Data Center, if you have permission, you can clone an existing role, add a new role, edit
newly created roles, or delete newly created roles.
