NEW QUESTION # 34
An administrator has a requirement to have consistent policy configuration and enforcement across NSX instances.
What feature of NSX fulfills this requirement?
- A. Policy-driven configuration
- B. Load balancer
- C. Federation
- D. Multi-hypervisor support
Answer: C
Explanation:
Federation is a feature of NSX that allows the administrator to manage multiple NSX instances with a single pane of glass view, create gateways and segments that span one or more locations, and configure and enforce firewall rules consistently across locations1. Federation provides centralized policy management for security and networking services for all locations and pushes it down to NSX Local Managers at the respective sites for enforcement1. Federation also enables disaster recovery and workload mobility scenarios by providing consistent network and security policies across different sites1.

NEW QUESTION # 35
Which is an advantages of a L2 VPN In an NSX 4.x environment?
- A. Achieve better performance
- B. Enables Multi-Cloud solutions
- C. Use the same broadcast domain
- D. Enables VM mobility with re-IP
Answer: C
Explanation:
L2 VPN is a feature of NSX that allows extending Layer 2 networks across different sites or clouds over an IPsec tunnel. L2 VPN has an advantage of enabling VM mobility with re-IP, which means that VMs can be moved from one site to another without changing their IP addresses or network configurations. This is possible because L2 VPN allows both sites to use the same broadcast domain, which means that they share the same subnet and VLAN .
NEW QUESTION # 36
Which of the following exist only on Tler-1 Gateway firewall configurations and not on Tier-0?
- A. Actions
- B. Profiles
- C. Applied To
- D. Sources
Answer: C
Explanation:
Explanation
According to the VMware NSX Documentation, Applied To is a feature that exists only on tier-1 gateway firewall configurations and not on tier-0. Applied To allows you to specify which logical router ports or segments are affected by a firewall rule. This can help reduce the scope and improve the performance of firewall rules.
By default, gateway firewall rules are applied to all the available uplinks and service interfaces on a selected gateway. For URL filtering, Applied To can only be Tier-1 gateways.

NEW QUESTION # 37
Sort the rule processing steps of the Distributed Firewall. Order responses from left to right.
Answer:
Explanation:
Explanation
The correct order of the rule processing steps of the Distributed Firewall is as follows:
* Packet arrives at vfilter connection table. If matching entry in the table, process the packet.
* If connection table has no match, compare the packet to the rule table.
* If the packet matches source, destination, service, profile and applied to fields, apply the action defined.
* If the rule table action is allow, create an entry in the connection table and forward the packet.
* If the rule table action is reject or deny, take that action.
This order is based on the description of how the Distributed Firewall works in the web search results1. The first step is to check if there is an existing connection entry for the packet in the vfilter connection table, which is a cache of flow entries for rules with an allow action. If there is a match, the packet is processed according to the connection entry. If there is no match, the packet is compared to the rule table, which contains all the security policy rules. The rules are evaluated from top to bottom until a match is found. The match criteria include source, destination, service, profile and applied to fields. The action defined by the matching rule is applied to the packet. The action can be allow, reject or deny. If the action is allow, a new connection entry is created for the packet and the packet is forwarded to its destination. If the action is reject or deny, the packet is dropped and an ICMP message or a TCP reset message is sent back to the source.

Display the uplink configured on the Tier-0 Gateways: You can use Network Topology to view the uplink interface and segment that connect your tier-0 gateways to your physical network. You can also view the VLAN ID and IP address of the uplink interface.
Display the VMs connected to Segments: You can use Network Topology to view the VMs that are attached to your segments. You can also view the IP address and MAC address of each VM.
NEW QUESTION # 46
What are two valid options when configuring the scope of a distributed firewall rule? (Choose two.)
- A. Segment Port
- B. DFW
- C. Segment
- D. Group
- E. Tier-1 Gateway
Answer: C,D
Explanation:
Explanation
C). Segment. This is correct. A segment is a logical construct that represents a layer 2 broadcast domain and a layer 3 subnet in NSX. A segment can be used to group and connect virtual machines, containers, or bare metal hosts that belong to the same application or service. A segment can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that enters or exits the segment12
E). Group. This is correct. A group is a logical construct that represents a collection of objects in NSX, such as segments, segment ports, virtual machines, IP addresses, MAC addresses, tags, or security policies. A group can be used to define dynamic membership criteria based on various attributes or filters. A group can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that matches the group membership criteria32
NEW QUESTION # 47
What are three NSX Manager rotes? (Choose three.)
- A. policy
- B. cloud
- C. manager
- D. master
- E. zookeepet
- F. controller
Answer: A,C,F
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.

NEW QUESTION # 50
Which two statements are true about IDS Signatures? (Choose two.)
- A. IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
- B. Users can upload their own IDS signature definitions.
- C. An IDS signature contains a set of instructions that determine which traffic is analyzed.
- D. An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
- E. An IDS signature contains data used to identify known exploits and vulnerabilities.
Answer: C,E
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.
NEW QUESTION # 51
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. It supports a 4-byte autonomous system number.
- C. BGP is enabled by default.
- D. EIGRP Is disabled by default.
- E. The network is divided into areas that are logical groups.
Answer: A,B,D
Explanation:
Explanation
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

When deploying an NSX Edge Transport Node, what two valid IP address assignment options should be specified for the TEP IP addresses? (Choose two.)
- A. Use RADIUS
- B. Use an IP Pool
- C. Use a DHCP Server
- D. Use a Static IP List
- E. Use BootP
Answer: B,D
Explanation:
Explanation
When deploying an NSX Edge Transport Node, two valid IP address assignment options that should be specified for the TEP IP addresses are Use an IP Pool and Use a Static IP List. These options allow the user to assign TEP IP addresses from a predefined range of IP addresses or a manually entered list of IP addresses, respectively345. The other options are incorrect because they are not supported methods for assigning TEP IP addresses. There is no option to use a DHCP server, RADIUS, or BootP for TEP IP address assignment in NSX-T345.

Which two CLI commands could be used to see if vmnic link status is down? (Choose two.)
- A. esxcfg-nics -1
- B. esxcli network nic list
- C. esxcli network vswitch dvs vmware list
- D. esxcfg-vmsvc/get.networks
- E. esxcfg-vmknic -1
Answer: A,B
Explanation:
The esxcli network nic list command lists all of the network interfaces on the ESXi host. The output of this command includes the link status of each interface.
The esxcfg-nics -1 command lists all of the network interfaces on the ESXi host in a single line.
The output of this command also includes the link status of each interface.
To see if the vmnic link status is down using the esxcli network nic list command, you can look at the Link column. If the Link status is Down, then the vmnic link is down.
To see if the vmnic link status is down using the esxcfg-nics -1 command, you can look at the Link Status column. If the Link Status is Down, then the vmnic link is down.
