2V0-41.23 VMware NSX 4.x Professional q75

QUESTION 1

Which three of the following describe the Border Gateway Routing Protocol (BGP) configuration on

a Tier-0 Gateway? (Choose three.)

Answer: ACE

Explanation:

It supports a 4-byte autonomous system number. – BGP supports both 2-byte and 4-byte

autonomous system numbers, but 4-byte autonomous system numbers are more common.

Can be used as an Exterior Gateway Protocol. – BGP is an Exterior Gateway Protocol (EGP),

which means that it can be used to exchange routing information between different autonomous

systems.

EIGRP is disabled by default. – EIGRP (Enhanced Interior Gateway Routing Protocol) is an

Interior Gateway Protocol (IGP), which means that it is used to exchange routing information within

an autonomous system. EIGRP is disabled by default on Tier-0 Gateways in NSX.

QUESTION 2

Which is an advantages of a L2 VPN in an NSX 4.x environment?

Answer: D

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.

QUESTION 3

Which NSX feature can be leveraged to achieve consistent policy configuration and simplicity

across sites?

Answer: D

Explanation:

NSX Federation: This feature allows you to create and manage a global network infrastructure that

spans across multiple sites using a single pane of glass. You can use this feature to synchronize

policies, segments, gateways, firewalls, VPNs, load balancers, and other network services across

sites.
