An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework must be close to the receivers within each AS. For high availability, if the sources in one AS are no longer available, the receivers of that AS must be able to receive the VoD content from the sources in another AS. Which feature must the design include?
A. SSM
B. anycast RP
C. bidirectional PIM
D. MSDP
A company's security policy requires that all connections between sites be encrypted in a manner that does not require maintenance of permanent tunnels. The sites are connected through a private MPLS-based service that uses a dynamically changing key and spoke-to-spoke communication. Which type of transport encryption must be used in this environment?
A. GETVPN
B. DMVPN
C. GRE VPN
D. standard IPsec VPN
An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a 100Mbps CIR. The ISP aggressively drops all traffic received over the CIR, which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution should the engineer choose?
A. policing
B. queuing
C. traffic shaping
D. policer with markdown
Which method does Cisco SD-WAN use to avoid fragmentation issues?
A. PMTUD is used.
B. Access circuits are configured with 1600 byte MTU settings.
C. Jumbo frames are enabled.
D. Traffic is marked with the DF bit set.
A global organization with several branches hired a network architect to design an overlay VPN solution. The branches communicate with each other frequently. The customer expects to add more branches in the future. To meet the customer's security requirements, the architect plans to provide traffic protection using dynamic IPsec tunnels. Which solution should the architect choose?
A. DMVPN
B. EasyVPN
C. L2TP
D. GETVPN
In the SD-WAN underlay network, which WAN Edge VPN ID is defined as the transport VPN and is used to carry control traffic?
A. VPN 0
B. VPN 512
C. VPN 128
D. VPN 256
An ISP provides Layer 3 VPN service over MPLS to a customer with four branches and multiple CE routers at each branch. To exchange the routes that are learned from the CE routers, which BGP address family should the ISP activate among the PE routers?
A. address-family multicast
B. L2VPN EVPN
C. VPNv4 unicast
D. IPv4 unicast
Which two functions does the control plane node provide in a Cisco SD-Access architecture? (Choose two.)
A. LISP proxy ETR
B. host tracking database
C. policy mapping
D. map server
E. endpoint registration
Which feature is used to optimize WAN bandwidth of IGMP network traffic among WAN Edge routers in the same VPN?
A. IGMPv2
B. multicast RP
C. multicast-replicator
D. multicast service routes
Which consideration must be made when designing a Cisco SD-Access fabric underlay?
A. Subnets must be reduced to decrease latency.
B. Up to six control planes are supported.
C. The default MTU should be increased.
D. A unified policy must be used.
