Company XYZ has 30 sites running a legacy private WAN architecture that connects to the Internet via multiple high- speed connections The company is now redesigning their network and must comply with these design requirements :
Use a private WAN strategy that allows the sites to connect to each other directly and caters for future expansion.
Use the Internet as the underlay for the private WAN.
Securely transfer the corporate data over the private WAN.
Which two technologies should be Incorporated into the design of this network? (Choose two.)

1. A. S-VTI
2. B. IPsec
3. C. DMVPN
4. D. GET VPN
5. E. PPTP

Correct Answer: BC

Company XYZ has two routing domains in their network, EIGRP and OSPF. The company wants to provide full reachability between the two domains by implementing redistribution on a router running both protocols. They need to design the redistribution in a way that the OSPF routers will see link costs added to external routes. How must the redistribution strategy be designed for this network?

1. A. Redistribute using metric type 2 into OSPF.
2. B. Redistribute using metric type 1 into OSPF.
3. C. Redistribute using metric type 1 into EIGRP.
4. D. Redistribute using metric type 2 into EIGRP.

Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal the multicast state hop-by-hop, but instead uses a link state protocol to advertise the multicast forwarding state?

1. A. Binary indexed explicit routing
2. B. Binary intermediate enhanced routing
3. C. Bit indexed explicit replication
4. D. Bi-directional implicit replication

Correct Answer: C

1. A. authentication VLAN
2. B. user VLAN
3. C. untrusted VLAN

Correct Answer: D

Which two statements describe the usage of the IS-IS overload bit technique? (Choose two )

1. A. lf overload-bit is set on a Level 2 intermediate system, the other Level 2 intermediate systems in the topology will stop using the overloaded IS to forward Level 2 traffic However, the intermediate system can still forward Level 1 traffic
2. B. It can be set in intermediate systems (IS-IS routers) to prioritize control plane CSNP packets.
3. C. It can be used to automatically synchronize the link-state database between Level 1 intermediate systems
4. D. It can be set in intermediate systems (IS-IS routers) to avoid traffic black holes until routing protocols are fully converged after a reload operation.
5. E. It can be set in intermediate systems (IS-IS routers) to attract transit traffic from other intermediate systems
