Referring to the exhibit, not all routes are being exchanged by EBGP peers.
In this scenario, which BGP parameter would solve this problem?
In EBGP (External Border Gateway Protocol) scenarios where routes are not being exchanged properly, the 'as-override' feature is relevant. This is often used in MPLS VPN environments where the same AS number might be used on both ends of the BGP session. The 'as-override' parameter allows the replacement of the originating AS number with the provider's AS number, thus resolving issues related to AS path filters that might prevent route exchange. Therefore, 'as-override' would solve the problem of routes not being exchanged by the EBGP peers in the given scenario.
You need to add perimeter security to the network shown in the exhibit. All traffic must be inspected for attacks. The edge routers are using all available ports.
Your solution must maintain both port and device resiliency.
In this scenario, which design would satisfy these requirements?
In this scenario, an inline SRX Series chassis cluster is the appropriate design choice. This configuration ensures both port and device resiliency. Placing SRX Series devices inline guarantees all traffic must pass through them for inspection, addressing the requirement for attack inspection. The chassis cluster configuration enhances device resiliency by providing redundancy and failover capabilities, ensuring network stability even if one device fails. Since the edge routers are using all available ports, an inline deployment is necessary to maintain functionality and security without requiring additional ports. Therefore, an inline SRX Series chassis cluster is the optimal solution for meeting the given requirements.
You are designing a network for a small data center.
In this scenario, which underlay protocol allows for the simplest implementation?
For a small data center, the simplest underlay protocol to implement is OSPF. OSPF is an Interior Gateway Protocol (IGP) that is straightforward to set up and manage, making it suitable for smaller networks. It does not require complex configurations like Autonomous System numbers, which are necessary for Border Gateway Protocols such as EBGP and IBGP. Therefore, OSPF offers a simpler and more efficient solution for smaller scale environments.
You are configuring VXLAN, and you must ensure that all switches for the multicast groups advertise their existence and learn about other VTEPs.
In this scenario, which protocol will accomplish this task?
Protocol Independent Multicast (PIM) is used to ensure that all switches for the multicast groups can advertise their existence and learn about other VTEPs in a VXLAN environment. PIM is designed to efficiently route multicast packets, making it the right protocol for managing multicast traffic in VXLAN.
Which statement is true about a Data Center Interconnect over an IP network?
Layer 2 data must be encapsulated when traversing an IP network because the IP network operates at Layer 3, which does not natively support Layer 2 frames. Encapsulation methods like VXLAN, GRE, or MPLS allow these Layer 2 frames to be transmitted over a Layer 3 IP network. This encapsulation is necessary to maintain the integrity and delivery of Layer 2 data between data centers.
