Online Access Free 4A0-115 Practice Test

Based upon the exhibit, which of the following statements is FALSE?

• A.A BGP export policy is required on PE3 and PE4 to ensure that IMET routes originated with VXLAN encapsulation are not advertised to the peer across the core network.
• B.On PE3 and PE4, VPLS 10 must be configured with two different route-distinguisher values: one for VXLAN and another for MPLS.
• C.VPLS 10 must be configured with two BGP instances on PE3 and PE4.
• D.On PE3 and PE4, VPLS 10 must be configured with two different route-target values: one for VXLAN and another for MPLS.

Examine the exhibit.

Which of the following configuration is NOT required to enable Layer-2 communication between CEI and CE2?

• A.Configure an MP-BGP session that allows the exchange of IPv4 labeled routes between PE3 and PE4.
• B.Configure a service distribution point (SDP) on PE3 to reach PE4, and another SDP on PE4 to reach PE3.
• C.Configure a local attachment circuit (AC) and a remote AC for VPWS 4 on all PE routers.
• D.Configure an MP-BGP session that allows the exchange of EVPN routes between PEI and PE3.

In the exhibit,

VPLS 20 is associated with a single-active Ethernet segment on routers PEI and PE3. Which of the following statementsis FALSE?

• A.PEI advertises an A-D per EVI route which includes a P flag set to I to indicate that PEI is the DF for EVI 20.
• B.When PEI learns MAC-01, it advertises a MAC/IP route which indicates that MAC-OI is associated with ESI I.
• C.PE3 advertises an A-D per ES route which indicates that ESI I is operating in a single-active redundancy mode.
• D.PEI advertises an A-D per ES route which indicates that ESI 1 is operating in a single-active redundancy mode.

Which of the following best describes the operation of a non-designated forwarder (non-DF) in a single-active Ethernet segment?

• A.Blocks Tx unicast, blocks Rx unicast, blocks Tx BUM, blocks Rx BUM
• B.Blocks Tx unicast, allows Rx unicast, blocks Tx BUM, allows Rx BUM
• C.Allows Tx unicast, blocks Rx unicast, allows Tx BUM, blocks Rx BUM
• D.Allows Tx unicast, allows Rx unicast, blocks Tx BUM, allows Rx BUM

Which of the following statements about PE-to-PE MAC address advertisement is FALSE?

• A.The service distinguisher (label or VNI) is advertised with the MAC/IP EVPN update.
• B.Route targets are used to uniquely identify routes between EVIS in the case of MAC address overlaps.
• C.A PE advertises locally-learned MAC addresses to remote PES using EVPN type-2 routes.
• D.A PE uses a single MP-BGP session with a remote peer to exchange the routes for all EVIs.
