B. VRF-Lite
C. QinQ
D. 802.3ad

When adding an IPSec headend termination device to your network design, which two performance indicators
are the most accurate to determine device scalability? (Choose two.)
A. CPU capabilities
B. bandwidth capabilities
C. packets per second capabilities
D. maximum tunnel termination capabilities

When creating a network design, which one of these options provides for basic Layer 2 client isolation to
prevent broadcast traffic exposure?
A. SVI

Which two aspects are considered when designing a dual hub, dual DMVPN cloud topology? (Choose two.)
A. recommended for high availability
54

B. requires all sites to have dual Internet connections
C. spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly
D. hub sites must connect to both DMVPN clouds

addressed in the design? (Choose two.)
A. network convergence
B. network accessibility
C. fault isolation
D. application scalability
E. user experience

You are planning the design of an encrypted WAN. IP packets will be transferred over encrypted GRE tunnels
between routers B and C. The packet size is limited to a maximum of 1500 bytes inside the WAN between
routers B and C. If endpoint 1 tries to send 1500-byte IP packets to endpoint 2, in what three ways will the
network design handle the fragmentation in three different possible network configurations? (Choose three.)
A. When router B fragments packets after the encryption, router C must reassemble these fragmented
packets.
B. When router B fragments packets before the encryption, router C must reassemble these fragmented
packets.
C. When router B fragments packets after the encryption, the endpoint 2 must reassemble these fragmented
packets.
D. When router B fragments packets before the encryption, endpoint 2 must reassemble these fragmented
packets.
E. When router A fragments packets, router C must reassemble these fragmented packets.
F. When router A fragments packets, endpoint 2 must reassemble these fragmented packets.

A many-to-many enterprise messaging application is using multicast as a transport mechanism. As partof the
network design for this application, which multicast address should be used, according to best practices
outlined in RFC 2365?
A. 224.0.0.60
B. 232.192.0.60
C. 239.128.0.60
D. 239.193.0.60

Which design concern should be accounted for in all Layer 3 virtualization technologies?
A. Layer 3 redundancy
B. packet sizing
C. application usage
D. Layer 3 stability

A company plans to establish a new network using Cisco Catalyst switches for its multicast applications. What
is the disadvantage when two multicast applications are using the multicast IP addresses 234.17.4.5 and
234.145.4.5 inside the same network?
A. Multicast packets from both applications are flooded to all Layer 2 ports in a segment where a multicast
receiver is located.
B. Multicast packets from both applications are flooded to ports where one multicast receiver from one
application is located.
C. Only one multicast stream is received at the port where the receivers from both applications are located.
D. Both multicast senders will always receive the multicast packets from the other multicast application.
E. The routers doing PIM-SM cannot distinguish between the two multicast applications.
