Question 7
What is the main advantage of using an Overlay Network in a data center?
Correct Answer: C
Question 8
Which statement is correct about IBGP?
Correct Answer: B
InIBGP (Internal Border Gateway Protocol), all routers within the same AS (Autonomous System) must have a logical full-mesh topology. This means that every IBGP router must be able to communicate with every other IBGP router directly or indirectly to ensure proper route propagation. Step-by-Step Breakdown: * Logical Full Mesh: * In an IBGP setup, routers do not re-advertise routes learned from one IBGP peer to another IBGP peer. This rule is in place to prevent routing loops within the AS. * To ensure full route propagation, alogical full meshis required, meaning every IBGP router must peer with every other IBGP router in the AS. This can be done either directly or via route reflection or confederation. * Physical Full Mesh Not Required:The physical topology does not need to be a full mesh, but the BGP peering relationships must form a logical full mesh. Techniques like route reflectors or BGP confederations can reduce the need for manual full-mesh peering. Juniper Reference: * IBGP Configuration: IBGP logical full mesh requirements can be simplified usingroute reflectorsto avoid the complexity of manually configuring many IBGP peers.
Question 9
What is the primary purpose of MAC address filtering on a switch?
Correct Answer: D
Question 10
A generated route is configured under which hierarchy?
Correct Answer: C
Agenerated routein Junos OS is configured under the[edit routing-options]hierarchy. Step-by-Step Breakdown: * Generated Routes:A generated route is created based on the presence of more specific routes in the routing table. It acts as a summary route and is generated when any of its contributing routes are active. This is commonly used to create aggregate routes in OSPF, BGP, or other protocols. * Configuration Hierarchy:The configuration for generated routes is placed under[edit routing-options] , where other static and routing policies are also defined. * Command Example: set routing-options generate route 10.10.0.0/16 Juniper Reference: * Routing Options: Juniper routers use the routing-options hierarchy to configure generated routes and other static routing behaviors.
