Question 1Choose one

Case Study: A rapidly growing e-commerce company, 'GlobalCart', is expanding its network. They currently operate a single Autonomous System (AS 65001) with 20 routers in a full iBGP mesh. The network engineering team is struggling to manage the configuration complexity and the high number of TCP sessions. The company plans to add 30 more routers within the next year. All routers are in a single administrative domain and require full visibility of all external routes. The lead architect wants a solution that simplifies configuration, reduces the number of iBGP peerings, and avoids partitioning the AS into sub-ASes. Which BGP scaling solution should the architect implement to meet these requirements? graph TD subgraph AS65001 [Current Full Mesh (AS 65001)] R1 --- R2 R1 --- R3 R1 --- R4 R2 --- R3 R2 --- R4 R3 --- R4 R1 --- R20(...) R2 --- R20(...) R3 --- R20(...) R4 --- R20(...) end subgraph Future [Future Growth] R21(...) R50(...) end AS65001 --> Future

Question 2Choose 2

Click the Exhibit button.You are troubleshooting a BGP connection.Referring to the exhibit, which two statements are correct? (Choose two.)

Question 3Choose 2

Click the Exhibit button.Referring to the exhibit, anycast RP is implemented to ensure multicast service availability. The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information.In this scenario, what are two methods to receive the active source information on R2? (Choose two.)

Question 4Choose one

You must ensure that only corporate devices, identified by MAC addresses, are allowed to connect and authenticate. Authentication must be handled by a centralized server to increase scalability.Which authentication method would satisfy this requirement?
