Questions 2

Referring to the exhibit, ServerA sends a single IP packet destined to 10.0.0.127.

Which two statements correctly describe the behavior of the resulting outbound VXLAN packets that contain the original packet destined to 10.0.0.127? (Choose two.)

Questions 2

Options:

Router E will replicate and send a copy of the received VXLAN packet to router D.

Router C will send a VXLAN packet destined only to router D and router E.

Router D will not replicate and send a copy of the received VXLAN packet to router E.

Router C will send a single VXLAN packet to one remote VTEP.

Questions 3

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.)

Options:

Configure the multipath option at the [edit protocols bgp group 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 routing-options] hierarchy.

Answer:

C, D

Explanation:

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:

shell

Copy code

set routing-options forwarding-table export load-balance-per-packet

Policy Definition Example:

shell

Copy code

set 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 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:

shell

Copy code

set routing-instances routing-options multipath

These 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.

Questions 4

Referring to the exhibit, how will router E quickly learn that the remote MAC addresses are no longer reachable through the router attached to the failed link?

Questions 4

Options:

Router E receives Type 2 withdrawal messages from router D.

Router E receives Type 1 withdrawal messages from router D.

Router E receives Type 1 withdrawal messages from router

Router E receives Type 2 withdrawal messages from router C.
