In which VPN type are the Virtual Tunnel interfaces (VTI) used?
D
Explanation:
Virtual Tunnel Interfaces (VTI) are used in route-based VPNs. In this type of VPN, the tunnel is treated
like a regular interface on the router. This allows for the configuration of routing protocols and the
application of routing decisions to the traffic flowing through the VPN tunnel. VTIs simplify the
management of routing and make it more flexible in VPN scenarios.
In an NSX environment, an administrator is observing low throughput and congestion between the
Tier-0 Gateway and the upstream physical routers.
Which two actions could address low throughput and congestion? (Choose two.)
A, C
Explanation:
Configure ECMP on the Tier-0 gateway: ECMP (Equal-Cost Multi-Path) allows multiple paths for traffic
between the Tier-0 Gateway and the upstream physical routers, effectively distributing the traffic
load and improving throughput. By enabling ECMP, you can reduce congestion and increase
bandwidth utilization, thus addressing performance issues.
Deploy Large size Edge node/s: Deploying larger Edge nodes can provide more resources (CPU,
memory, and network interfaces) to handle higher throughput and reduce congestion. This is
especially important if the existing Edge node is overwhelmed by the amount of traffic.
A company security policy requires all users to log into applications using a centralized
authentication system.
Which two authentication, authorization, and accounting (AAA) systems are available when
integrating NSX with VMware Identity Manager? (Choose two.)
A, D
Explanation:
RSA SecureID: RSA SecureID is a commonly used two-factor authentication (2FA) system that can
integrate with VMware Identity Manager for enhanced security during authentication, making it a
suitable AAA system for user authentication.
LDAP and OpenLDAP based on Active Directory (AD): VMware Identity Manager can integrate with
LDAP and OpenLDAP directories, including Active Directory (AD), for centralized user authentication.
This allows users to authenticate against an organization's directory service.
An NSX administrator would like to export syslog events that capture messages related to NSX host
preparation events.
Which message ID (msgid) should be used in the syslog export configuration command as a filter?
A
Explanation:
In NSX, the FABRIC message ID is used to capture and export syslog events related to host
preparation and other fabric-related activities. These events are important for tracking and
troubleshooting the setup and configuration of NSX components across the fabric, including host
preparation events.
An NSX administrator wants to create a Tier-0 Gateway to support equal cost multi-path (ECMP)
routing.
Which failover detection protocol must be used to meet this requirement?
D
Explanation:
To support Equal-Cost Multi-Path (ECMP) routing in an NSX environment, Bidirectional Forwarding
Detection (BFD) must be used for failover detection. BFD is a rapid failure detection protocol that
works with ECMP to provide fast failure detection between routers. It helps in detecting link failures
more quickly than traditional protocols, ensuring that traffic is routed through available paths as
quickly as possible.
An administrator has connected two virtual machines on the same overlay segment. Ping between
both virtual machines is successful.
What type of network boundary does this represent?
B
Explanation:
When two virtual machines are connected on the same overlay segment, they are part of the same
Layer 2 broadcast domain. In this case, the communication between the two VMs is happening
within the same broadcast domain, which means that broadcast traffic can be sent to all devices on
the segment. Since the ping is successful, the two VMs can communicate directly over Layer 2
without needing routing.
What are two supported host switch modes? (Choose two.)
C, D
Explanation:
Standard Datapath: This is the traditional mode used by the NSX host switch. It is typically used in
environments where performance requirements are standard and no special acceleration techniques
are needed.
Enhanced Datapath: This mode is designed to improve performance and provide better scalability,
especially for environments with higher traffic loads or more demanding applications. It can provide
better performance in certain scenarios by improving packet processing efficiency.
Which is an advantage of an L2 VPN in an NSX 4.x environment?
B
Explanation:
An L2 VPN (Layer 2 VPN) in an NSX 4.x environment allows you to extend a Layer 2 network across
different sites or data centers. This enables the connected environments to share the same broadcast
domain, meaning that broadcast traffic can be transmitted between sites as if they were on the same
local network. This is particularly useful for scenarios where you need to maintain Layer 2
connectivity across geographically dispersed locations.
Which two steps must an NSX administrator take to integrate VMware Identity Manager in NSX to
support role-based access control? (Choose two.)
B, C
Explanation:
Adding NSX Manager as a Service Provider (SP) in VMware Identity Manager is necessary to enable
SAML-based single sign-on (SSO), which allows VMware Identity Manager to manage and
authenticate users accessing NSX.
Entering the Identity Provider (IdP) metadata URL in NSX Manager is required to establish a
connection between NSX and VMware Identity Manager, enabling NSX to use VMware Identity
Manager as the IdP for authentication.
Which of the two following characteristics about NAT64 are true? (Choose two.)
C, E
Explanation:
NAT64 is supported on both Tier-0 and Tier-1 gateways, allowing for IPv6-to-IPv4 address translation
at different gateway levels within NSX.
NAT64 requires the Tier-1 gateway to be configured in active-standby mode, as this configuration
ensures stateful translation and consistency for IPv6-to-IPv4 traffic handling.
