Free Nokia 4A0-D03 Exam Dumps Questions & Answers

A host is connected to multiple PEs through multi-homing.
Which of the following is NOT a function of the EVPN route-type 4 route?

• A.  Identifies the type of algorithm to be used in the election process.
• B.  Allows the other PEs to discover which PEs are connected to the same Ethernet segment.
• C.  Identifies the redundancy mode of the Ethernet segment.
• D.  Triggers the election of a designated forwarder.

e-BGP is used as the routing protocol in the data center underlay.
When configuring the EVPN MP-BGP route reflector sessions, which of the following statements is FALSE?

• A.  The leaf's underlay autonomous system number is used for the route reflector EVPN peering sessions.
• B.  If redundant route reflectors are deployed, the client leaf routers will receive duplicated updates.
• C.  A second route reflector can be deployed for redundancy purposes.
• D.  The cluster-id that uniquely identifies the route reflector is only configured on the route reflector itself.

Consider the exhibit.

All connected leaf routers have the same Ethernet segment configuration. The IP-VRF is configured properly and is operational.
Which of the following statements is FALSE?

• A.  This Ethernet segment is configured for Layer 3 multi-homing.
• B.  The EVI for the IP-VRF using this segment is 1000.
• C.  A LAG must be configured on the connected leaf routers and the host.
• D.  The redundancy mode for this Ethernet segment is all-active.

Which of the following statements about PE-CE routing is FALSE?

• A.  eBGP is preferred which means that the PE and CE are required to be in different autonomous systems.
• B.  There are two methods to implement routing between the PE and CE, static and dynamic.
• C.  The CE advertises BGP EVPN route type 5 updates to the PE and the PE forwards to other PEs.
• D.  BGP is the preferred option for PE-CE routing as it scales better than static routing.

Leaf routers are configured to support Layer 2 multi-homing all-active mode.
Which of the following statements is FALSE?

• A.  If using LACP, the system-id-mac must uniquely identify each leaf router connected to the host.
• B.  If VLAN tagging is to be used, then it must be enabled on the LAG interface.
• C.  The LAG interface must then be associated with the Ethernet segment.
• D.  A LAG must be configured on the participating leaf routers.
