VMware 2V0-41.23 - VMware NSX 4.x Professional

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.

According to the VMware NSX Documentation, Switch Visualization is a feature in the NSX UI that shows the mapping between the virtual NIC and the host’s physical adapter for virtual machines running on an ESXi transport node. You can use Switch Visualization to view details such as port ID, MAC address, VLAN ID, IP address, MTU, port state, port speed, port type, and port group for each virtual NIC and physical adapter.

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. References: Gateway Firewall

According to the VMware NSX 4.x Professional documents and tutorials, a RouterLink port is a logical port that connects a Tier-1 gateway to a Tier-0 gateway. This port is automatically created when a Tier-1 gateway is associated with a Tier-0 gateway from the NSX UI or API. The RouterLink port enables routing between the two gateways and carries all the routing protocols and traffic. There is no need to manually create a logical switch or segment for this purpose1.

The correct answer is to enable the option All LB VIP Routes on the Tier-1 gateway route advertisement settings. This option allows the Tier-1 gateway to advertise the NSX Advanced Load Balancer LB VIP routes to the Tier-0 gateway and other peer routers, so that the end users can reach the production website by using the VIP address1. The other options are not relevant for this scenario.

To mark the correct answer by clicking on the image, you can click on the toggle switch next to All LB VIP Routes to turn it on. The switch should change from gray to blue, indicating that the option is enabled. See the image below for reference:

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.

An NSX administrator can use TCP, UDP, or TLS protocols to transfer log messages to a remote log server. These protocols are supported by NSX Manager, NSX Edge, and hypervisors for remote logging. A Log Insight log server supports all these protocols, as well as LI and LI-TLS, which are specific to Log Insight and optimize network usage. HTTPS, SSH, and SSL are not valid protocols for remote logging in NSX-T Data Center. References: : VMware NSX-T Data Center Administration Guide, page 102. : VMware Docs: Configure Remote Logging

Two tools that are used for centralized logging in VMware NSX are Syslog Server and VMware Aria Operations for Logs. Syslog Server is a standard protocol for sending log messages from various network devices to a centralized server1. VMware NSX supports syslog for long term retention of logs and all NSX components can send syslog messages to a configured syslog server2. VMware Aria Operations for Logs is a VMware product that provides intelligent log analytics for NSX3. It provides monitoring and troubleshooting capabilities and customizable dashboards for network virtualization, flow analysis, and alerts3. The other options are incorrect because they are not tools for centralized logging in VMware NSX. VMware Aria Operations is a VMware product that provides operations management and automation for NSX4, but it is not the same as VMware Aria Operations for Logs. VMware Aria Automation is a VMware product that provides automation and orchestration for NSX5, but it is not related to logging. VMware Aria Operations for Networks is not a valid product name. References: Syslog, NSX Logging and System Events, VMware vRealize Log Insight for NSX, VMware vRealize Operations Management Pack for NSX, VMware vRealize Automation

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. References: 2: Understanding ECMP Routing - VMware Docs(https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-443B6B0D-F179-429E-83F3-E136038332E0.html)  1: NSX Edge VM System Requirements - VMware Docs(https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/installation/GUID-22F87CA8-01A9-4F2E-B7DB-9350CA60EA4E.html)

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. References: 1: NSX Federation - VMware Docs(https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-D5B6DC79-6733-44A7-8072-50221CF2122A.html)
