An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A. providing Layer 2 connectivity between a central site and approximately 100 remote sites. Customer A wants to use the VPLS network to carry its internal multicast video feeds which are sourced at the central site and consist of 20 groups at Mbps each. Which service provider recommendation offers the most scalability?

• A.EoMPLS-based VPLS can carry multicast traffic in a scalable manner
• B.Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites
• C.Use a mesh of GRE tunnels to carry the streams between sites
• D.Enable snooping mechanisms on the provider PE routers.

Company XYZ uses an office model where the employees can use any open desk and plug their laptops in. They want to authenticate the end users using their domain username and password before allowing them access to the network. The design must also accommodate the ability of controlling traffic within the same group or subnet if a macro (or micro) segmentation-based model is adopted in the future. Which protocol can be recommended for this design to authenticate end users?

• A.LDAP
• B.EAP
• C.TACACS+
• D.RADIUS

Which design benefit of bridge assurance is true?

• A.It supposes a spanning-tee topology change upon connecting and disconnecting a station on a port
• B.It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.
• C.It prevents switch loops caused by unidirectional point-to-point link condition on Rapid PVST + and MST
• D.It prevents switched traffic from traversing suboptimal paths on the network.
