NO.85 Your enterprise network uses routing instances to support multitenancy. Your Junos devices use BGP to peer to multiple BGP devices. You must ensure that load balancing is achieved within the routing instance.Which two statements would accomplish this task? (Choose two.)  Configure the multipath option at the [edit protocols bgp group <group-name> neighbor] hierarchy.  Configure the multipath option at the [edit protocols bgp group] hierarchy.  Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding-table] hierarchy.  Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy. * Multitenancy with Routing Instances:* In a multitenant network, different tenants are isolated using routing instances.* Each routing instance can have its own routing table and policies.* BGP and Load Balancing:* BGP (Border Gateway Protocol) is often used for interconnecting different autonomous systems or for internal routing.* Load balancing in BGP can be achieved using the multipath feature, which allows the installation of multiple paths to the same destination in the routing table.* Additionally, configuring per-packet load balancing ensures that traffic is distributed across multiple paths more granularly.* Configuring Multipath in BGP:* Hierarchy Considerations: The multipath option must be configured at appropriate hierarchies to ensure it applies to the correct scope (either globally or within a specific routing instance).Detailed Configuration:Statement C: Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding-table] hierarchy.* Correct: Configuring a load-balance per-packet policy ensures that packets are distributed evenly across multiple paths. This is crucial for achieving effective load balancing.Configuration Example:shellCopy codeset routing-options forwarding-table export load-balance-per-packetPolicy Definition Example:shellCopy codeset policy-options policy-statement load-balance-per-packet term 1 then load-balance per-packet Statement D: Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy.* Correct: Configuring multipath within a routing instance ensures that the load balancing feature is applied specifically to that instance, which is crucial in a multitenant environment.Configuration Example:shellCopy codeset routing-instances <instance-name> routing-options multipathReferences:* Useful Juniper Commands* Juniper Routing Instances and Multipath ConfigurationThese configurations ensure that load balancing is achieved within each routing instance, leveraging both per-packet load balancing and the multipath feature in Junos OS for BGP. By configuring at the forwarding-table and routing-instance levels, you ensure the load balancing behavior is correctly applied to achieve the desired network performance and redundancy.NO.86 You have a workstation and an IP phone that connect to the same physical port on your Juniper switch. Which statement is true?  You must configure two logical interfaces on the switch port.  The workstation and the phone both must send tagged traffic to the switch.  The switch port must be configured as a trunk port.  The access port can be configured to accept tagged and untagged traffic.

Level 1/2 routers automatically inject a default route to the nearest Level 1 router. It’s the other way aroundNO.90 You are asked to merge a RIP network with your OSPF network. As a first step, you establish connectivity between the RIP network and the OSPF network. The RIP network connects to an NSSA area. Which two statements are true in this scenario? (Choose two.)  To share RIP routes with the OSPF network, an export policy will be required on the ABR.  To share RIP routes with the OSPF network, an export policy will be required on the ASBR.  By default, external OSPF routes have a higher route preference than RIP routes.  Be default, RIP routes have a higher route preference than external OSPF routes. Route Preference ValuesOSPF Internal = 10RIP = 100OSPF External = 150NO.91 You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.In this scenario, which area is needed to accomplish this task?  totally non-to-stubby area  totally stubby area  stub area  non-to-stubby area A totally stubby area (TSA) is a stub area in which summary link-state advertisement (type 3 LSAs) are not sent. A default summary LSA, with a prefix of 0.0. 0.0/0 is originated into the stub area by an ABR, so that devices in the area can forward all traffic for which a specific route is not known, via ABR.NO.92 You are asked to configure 802.1X on your access ports to allow only a single device to authenticate.In this scenario, which configuration would you use?  multiple supplicant mode  MAC authentication mode  single-secure supplicant mode  single supplicant mode Single supplicant mode authenticates only the first end device that connects to an authenticator port. All other end devices connecting to the authenticator port after the first has connected successfully, whether they are802.1X-enabled or not, are permitted access to the port without further authentication. If the first authenticated end device logs out, all other end devices are locked out until an end device authenticates. Single-secure supplicant mode authenticates only one end device to connect to an authenticator port. No other end device can connect to the authenticator port until the first logs outNO.93 You are running OSPF as your IGP. The interfaces connecting two routers are in the ExStart state. You notice that something is incorrect with the configuration. Referring to the exhibit, which statement is correct?  The subnet mask is incorrect.  The MTU setting are incorrect.  The interface type is incorrect.  The IP addresses are incorrect.
