質問 # 68
What are three NSX Manager rotes? (Choose three.)
- A. cloud
- B. policy
- C. master
- D. controller
- E. zookeepet
- F. manager
正解：B、D、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 # 69
Where in the NSX UI would an administrator set the time attribute for a time-based Gateway Firewall rule?
- A. There Is no option in the NSX UI. It must be done via command line interface.
- B. The option to set time-based rule is a clock Icon in the rule.
- C. The option to set time-based rule is a clock Icon in the policy.
- D. The option to set time based rule is a field in the rule Itself.
正解：C
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.

BFD can be used with ECMP routing to monitor the health of the ECMP paths and trigger a route change in case of a failure. BFD is supported by both BGP and OSPF routing protocols in NSX-T. BFD can also be configured with different timers to achieve different detection times.
質問 # 76
Refer to the exhibit.
An administrator configured NSX Advanced Load Balancer to redistribute the traffic between the web servers.
However, requests are sent to only one server
Which of the following pool configuration settings needs to be adjusted to resolve the problem? Mark the correct answer by clicking on the image.
正解：
解説：
Explanation
Load Balancing Algorithm
You specify the following parameters during the creation of a server pool:
* Name: A unique name for the server pool.
* Cloud: The cloud connector details for the NSX environment.
* VRF Context: Virtual Routing Framework (VRF) is a method to isolate traffic in a system. VRF is also called a route domain in the load balancer community. A global VRF context is created by default. Network administrators might create custom VRF contexts to isolate traffic between different tenants or subsets.
* Default Server Port: New connections to servers will use this destination service port. The default port is 80.
* Load-balancing algorithm: The selected load-balancing algorithm controls how the incoming connections are distributed among the servers in the pool.
* Tier-1 gateway (logical router): Specify the Tier-1 gateway that you want to attach the server pool to. This value matches the Tier-1 gateway specified for the virtual service and VIP.
質問 # 77
Which command on ESXI is used to verify the Local Control Plane connectivity with Central Control Plane?
- A.
- B.
- C.
- D.
正解：C
解説：
According to the web search results, the command that is used to verify the Local Control Plane (LCP) connectivity with Central Control Plane (CCP) on ESXi is get control-cluster status. This command displays the status of the LCP and CCP components on the ESXi host, such as the LCP agent, CCP client, CCP server, and CCP connection. It also shows the IP address and port number of the CCP server that the LCP agent is connected to. If the LCP agent or CCP client are not running or not connected, it means that there is a problem with the LCP connectivity .
質問 # 78
Which two are requirements for FQDN Analysis? (Choose two.)
- A. ESXi control panel requires access to the Internet to download category and reputation definitions.
- B. The NSX Manager requires access to the Internet to download category and reputation definitions.
- C. A layer 7 gateway firewall rule must be configured on the Tier-1 gateway uplink.
- D. A layer 7 gateway firewall rule must be configured on the Tier-0 gateway uplink.
- E. The NSX Edge nodes require access to the Internet to download category and reputation definitions.
正解：C、E
解説：
FQDN Analysis is a feature of NSX that uses DNS snooping to identify the FQDNs that are being accessed by virtual machines on your network. FQDN Analysis then uses category and reputation definitions to classify the FQDNs and identify any potential security risks.
To use FQDN Analysis, you need to configure a layer 7 gateway firewall rule on the Tier-1 gateway uplink. This firewall rule will allow DNS traffic to pass through the Tier-1 gateway so that FQDN Analysis can snoop on the DNS traffic and identify the FQDNs that are being accessed.
The NSX Edge nodes also need access to the Internet so that they can download the category and reputation definitions that are used by FQDN Analysis.
質問 # 79
What can the administrator use to identify overlay segments in an NSX environment if troubleshooting is required?
- A. VLAN ID
- B. Segment ID
- C. VNI ID
- D. Geneve ID
正解：C
解説：
A segment is mapped to a unique Geneve segment that is distributed across the ESXi hosts in a transport zone. The Geneve segment uses a virtual network identifier (VNI) as an overlay network identifier. The VNI ID can be used to identify overlay segments in an NSX environment if troubleshooting is required.
質問 # 80
Which three DHCP Services are supported by NSX? (Choose three.)
- A. VRF DHCP Server
- B. Gateway DHCP
- C. Port DHCP per VNF
- D. Segment DHCP
- E. DHCP Relay
正解：B、D、E
解説：
According to the VMware NSX Documentation1, NSX-T Data Center supports the following types of DHCP configuration on a segment:
* Local DHCP server: This option creates a local DHCP server that has an IP address on the segment and provides dynamic IP assignment service only to the VMs that are attached to the segment.
* Gateway DHCP server: This option is attached to a tier-0 or tier-1 gateway and provides DHCP service to the networks (overlay segments) that are directly connected to the gateway and configured to use a gateway DHCP server.
* DHCP Relay: This option relays the DHCP client requests to the external DHCP servers that can be in any subnet, outside the SDDC, or in the physical network.

Which statement is true about an alarm in a Suppressed state?
- A. An alarm can be suppressed for a specific duration in minutes.
- B. An alarm can be suppressed for a specific duration in seconds.
- C. An alarm can be suppressed for a specific duration in hours.
- D. An alarm can be suppressed for a specific duration in days.
正解：C
解説：
The answer is D. 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 To learn more about how to manage alarm states in NSX, you can refer to the following resources:
