質問 # 40
Which command is used to set the NSX Manager's logging-level to debug mode for troubleshooting?
- A. Set service manager logging-level debug
- B. Set service nsx-manager log-level debug
- C. Set service nsx-manager logging-level debug
- D. Set service manager log-level debug
正解：A
解説：
According to the VMware Knowledge Base article 1, the CLI command to set the log level of the NSX Manager to debug mode is set service manager logging-level debug. This command can be used when the NSX UI is inaccessible or when troubleshooting issues with the NSX Manager1. The other commands are incorrect because they either use a wrong syntax or a wrong service name. The NSX Manager service name is manager, not nsx-manager2. The log level parameter is logging-level, not log-level3.
質問 # 41
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 policy.
- B. The option to set time based rule is a field in the rule Itself.
- C. There Is no option in the NSX UI. It must be done via command line interface.
- D. The option to set time-based rule is a clock Icon in the rule.
正解：A
解説：
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.
質問 # 42
What are three NSX Manager rotes? (Choose three.)
- A. cloud
- B. manager
- C. policy
- D. controller
- E. zookeepet
- F. master
正解：B、C、D
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.

- C. VPNs can be configured on the command line Interface on the NSX manager.
- D. IPSec VPNs use the DPDK accelerated performance library.
正解：B、D
解説：
According to the VMware NSX 4.x Professional documents and tutorials, IPSec VPN secures traffic flowing between two networks connected over a public network through IPSec gateways called endpoints. NSX Edge supports a policy-based or a route-based IPSec VPN. Beginning with NSX-T Data Center 2.5, IPSec VPN services are supported on both Tier-0 and Tier-1 gateways1. NSX Edge also leverages the DPDK accelerated performance library to optimize the performance of IPSec VPN2.
質問 # 45
Which two statements are true about IDS Signatures? (Choose two.)
- A. An IDS signature contains data used to identify known exploits and vulnerabilities.
- B. An IDS signature contains a set of instructions that determine which traffic is analyzed.
- C. IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
- D. Users can upload their own IDS signature definitions.
- E. An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
正解：A、B
解説：
Explanation
According to the Network Bachelor article1, an IDS signature contains data used to identify an attacker's attempt to exploit a known vulnerability in both the operating system and applications. This implies that statement B is true. According to the VMware NSX Documentation2, IDS/IPS Profiles are used to group signatures, which can then be applied to select applications and traffic. This implies that statement E is true. Statement A is false because users cannot upload their own IDS signature definitions, they have to use the ones provided by VMware or Trustwave3. Statement C is false because an IDS signature does not contain data used to identify the creator of known exploits and vulnerabilities, only the exploits and vulnerabilities themselves. Statement D is false because IDS signatures are classified into one of the following severity categories: Critical, High, Medium, Low, or Informational1.
質問 # 46
An administrator has deployed 10 Edge Transport Nodes in their NSX Environment, but has forgotten to specify an NTP server during the deployment.
What is the efficient way to add an NTP server to all 10 Edge Transport Nodes?
- A. Use Transport Node Profile
- B. Use the CU on each Edge Node
- C. Use a Node Profile
- D. Use a PowerCU script
正解：C
解説：
A node profile is a configuration template that can be applied to multiple NSX Edge nodes or transport nodes at once. A node profile can include settings such as NTP server, DNS server, syslog server, and so on1. By using a node profile, an administrator can efficiently configure or update the network settings of multiple NSX Edge nodes or transport nodes in a single operation2. The other options are incorrect because they are either not efficient or not supported. Using the CLI on each Edge node would require manual and repetitive commands for each node, which is not efficient. Using a Transport Node Profile would not work, because a Transport Node Profile is used to configure the NSX-T Data Center components on a transport node, such as the transport zone, the N-VDS, and the uplink profiles3. Using a PowerCLI script might work, but it would require writing and testing a custom script, which is not as efficient as using a built-in feature like a node profile.

When configuring OSPF on a Tler-0 Gateway, which three of the following must match in order to establish a neighbor relationship with an upstream router? (Choose three.)
- A. Address of the neighbor
- B. Subnet mask
- C. Protocol and Port
- D. Area ID
- E. Naming convention
- F. MTU of the Uplink
正解：B、D、F
解説：
ccording to the VMware NSX Documentation, these are the three parameters that must match in order to establish an OSPF neighbor relationship with an upstream router on a tier-0 gateway:
MTU of the Uplink: The maximum transmission unit (MTU) of the uplink interface must match the MTU of the upstream router interface. Otherwise, OSPF packets may be fragmented or dropped, causing neighbor adjacency issues.
Subnet mask: The subnet mask of the uplink interface must match the subnet mask of the upstream router interface. Otherwise, OSPF packets may not reach the correct destination or be rejected by the upstream router.
Area ID: The area ID of the uplink interface must match the area ID of the upstream router interface. Otherwise, OSPF packets may be ignored or discarded by the upstream router.

An NSX administrator would like to export syslog events that capture messages related to NSX host preparation events. Which message ID (msgld) should be used in the syslog export configuration command as a filler?
- A. GROUPING
- B. FABRIC
- C. SYSTEM
- D. MONISTORING
正解：B
解説：
According to the VMware NSX Documentation2, the FABRIC message ID (msgld) captures messages related to NSX host preparation events, such as installation, upgrade, or uninstallation of NSX components on ESXi hosts. The syslog export configuration command for NSX host preparation events would look something like this:
set service syslog export FABRIC
The other options are either incorrect or not relevant for NSX host preparation events. MONITORING captures messages related to NSX monitoring features, such as alarms and system events2. SYSTEM captures messages related to NSX system events, such as login, logout, or configuration changes2. GROUPING captures messages related to NSX grouping objects, such as security groups, security tags, or IP sets2.

質問 # 60
Which TraceFlow traffic type should an NSX administrator use tor validating connectivity between App and DB virtual machines that reside on different segments?
- A. Broadcast
- B. Multicast
- C. Unicast
- D. Anycast
正解：C
解説：
Unicast is the traffic type that an NSX administrator should use for validating connectivity between App and DB virtual machines that reside on different segments. According to the VMware documentation1, unicast traffic is the traffic type that is used to send a packet from one source to one destination. Unicast traffic is the most common type of traffic in a network, and it is used for applications such as web browsing, email, file transfer, and so on2. To perform a traceflow with unicast traffic, the NSX administrator needs to specify the source and destination IP addresses, and optionally the protocol and related parameters1. The traceflow will show the path of the packet across the network and any observations or errors along the way3. The other options are incorrect because they are not suitable for validating connectivity between two specific virtual machines. Multicast traffic is the traffic type that is used to send a packet from one source to multiple destinations simultaneously2. Multicast traffic is used for applications such as video streaming, online gaming, and group communication4. To perform a traceflow with multicast traffic, the NSX administrator needs to specify the source IP address and the destination multicast IP address1. Broadcast traffic is the traffic type that is used to send a packet from one source to all devices on the same subnet2. Broadcast traffic is used for applications such as ARP, DHCP, and network discovery. To perform a traceflow with broadcast traffic, the NSX administrator needs to specify the source IP address and the destination MAC address as FF:FF:FF:FF:FF:FF1. Anycast traffic is not a valid option, as it is not supported by NSX Traceflow. Anycast traffic is a traffic type that is used to send a packet from one source to the nearest or best destination among a group of devices that share the same IP address. Anycast traffic is used for applications such as DNS, CDN, and load balancing.
質問 # 61
Which three of the following describe the Border Gateway Routing Protocol (BGP) configuration on a Tier-0 Gateway? (Choose three.)
- A. Can be used as an Exterior Gateway Protocol.
- B. BGP is enabled by default.
- C. The network is divided into areas that are logical groups.
- D. It supports a 4-byte autonomous system number.
- E. FIGRP Is disabled by default.
正解：A、D、E
解説：
Explanation
The answer is A, B, and D.
A). Can be used as an Exterior Gateway Protocol. This is correct. BGP is a protocol that can be used to exchange routing information between different autonomous systems (AS). An AS is a network or a group of networks under a single administrative control. BGP can be used as an Exterior Gateway Protocol (EGP) to connect an AS to other ASes on the internet or other external networks1
B). It supports a 4-byte autonomous system number. This is correct. BGP supports both 2-byte and 4-byte AS numbers. A 2-byte AS number can range from 1 to 65535, while a 4-byte AS number can range from 65536 to 4294967295. NSX supports both 2-byte and 4-byte AS numbers for BGP configuration on a Tier-0 Gateway2
C). The network is divided into areas that are logical groups. This is incorrect. This statement describes OSPF, not BGP. OSPF is another routing protocol that operates within a single AS and divides the network into areas to reduce routing overhead and improve scalability. BGP does not use the concept of areas, but rather uses attributes, policies, and filters to control the routing decisions and traffic flow3
D). FIGRP Is disabled by default. This is correct. FIGRP stands for Fast Interior Gateway Routing Protocol, which is an enhanced version of IGRP, an obsolete routing protocol developed by Cisco. FIGRP is not supported by NSX and is disabled by default on a Tier-0 Gateway.
E). BGP is enabled by default. This is incorrect. BGP is not enabled by default on a Tier-0 Gateway. To enable BGP, you need to configure the local AS number and the BGP neighbors on the Tier-0 Gateway using the NSX Manager UI or API.
To learn more about BGP configuration on a Tier-0 Gateway in NSX, you can refer to the following resources:
* VMware NSX Documentation: Configure BGP 1
* VMware NSX 4.x Professional: BGP Configuration
* VMware NSX 4.x Professional: BGP Troubleshooting
