질문 # 19
Your OSPF network consists of a mix of 1GbE and 10GbE interfaces. By default, all interfaces have the same cost in your OSPF network. You are asked to ensure that the 10GbE interfaces are more preferred when available In this scenario, which two statements would accomplish this behavior? (Choose two.)
정답：A,C
설명：
OSPF determines the best path to a destination by calculating themetric (cost)of each link. By default, Junos OS uses areference bandwidthof100 Mbpsto calculate this cost using the formula:
When the reference bandwidth is left at the default 100 Mbps, any interface with a speed of 100 Mbps or higher (including 1 GbE and 10 GbE) is assigned a cost of1because the minimum OSPF cost is 1. This results in equal-cost paths, preventing the router from preferring the faster 10 GbE link.
To ensure 10 GbE interfaces are preferred, you must create a cost differential:
* Option A (Reference Bandwidth):By increasing the reference bandwidth to10G(or higher), the calculation changes. For a 10 GbE link, the cost becomes $10,000 / 10,000 = 1$. For a 1 GbE link, the cost becomes $10,000 / 1,000 = 10$. Since OSPF prefers the path with thelowest cumulative cost, the
10 GbE link is now preferred.
* Option D (Manual Metric):You can manually override the automatic cost calculation by assigning a higher metric specifically to the 1 GbE interfaces. If a 1 GbE interface is manually set to a cost of 50 and the 10 GbE interface remains at 1 (or is set to a lower value), the router will prioritize the 10 GbE path.
Option Bis incorrect because a higher metric makes a pathlesspreferred.Option Cis incorrect because a 1G reference bandwidth would still result in both 1 GbE and 10 GbE interfaces having a cost of 1.
질문 # 20
Exhibit.
You have determined that traffic in your network is being routed through your route reflector instead of using the optimal path. Referring to the exhibit, what are two configuration changes on the route reflector that would solve the problem? (Choose two.)
정답：A,B
설명：
The exhibit shows a BGP Route Reflector (RR) configuration where an export policy named NHS (Next-Hop Self) is applied to the internal BGP group int-group. The policy NHS sets the next-hop self attribute for BGP routes.
* The Problem (Traffic Tromboning):In a standard BGP Route Reflector design, the RR should reflect routes without modifying the BGP next-hop attribute. By applying a next-hop self policy on the export to clients, the RR tells all its clients thatitis the exit point for those routes. Consequently, all data plane traffic is sent to the RR first before being forwarded to the actual destination, rather than following the optimal direct path between clients. This is known as "traffic tromboning" or suboptimal routing.
* The Solution (Option C):The most direct way to fix this is todelete the export policythat is forcing the next-hop to be the RR. By deleting protocols bgp group int-group export NHS, the RR will resume standard behavior and reflect the original next-hop received from the route source, allowing clients to route traffic directly to the correct destination.
* The Refined Solution (Option D):If you must keep the NHS policy (perhaps for routes learned from external peers), you should ensure it only applies to those specific routes. By adding from route-type internal to the policy term and then potentially changing the logic (or simply narrowing the scope), you can prevent the RR from incorrectly applying next-hop self to internal routes that it is merely reflecting.
In the context of this specific problem,Option Dcombined with a change in the policy's action or scope helps ensure reflected internal routes maintain their original, optimal next-hops.
* Option Ais incorrect because setting next-hop self for external routes is common practice, but it doesn't solve the problem of internal reflected routes being diverted to the RR.
* Option Bis incorrect because applying this as an import policy would change how the RR itself sees the routes, but it wouldn't fix the attributes being sent out to the clients in the reflection process.
질문 # 21
What is the primary function of MSDP within a multicast network?
정답：A
질문 # 22
Referring to the exhibit, which statement is correct when a failure exists on the link between host2 and switch5 on this EVPN-VXLAN fabric?
정답：A
설명：
Type 1 routes are used for per-ES auto-discovery (A-D) to advertise EVPN multi-homing mode.
Remote ToR leaf devices in the EVPN network use the EVPN Type 1 route type functionality to learn the EVPN Type 2 MAC routes from other leaf devices. In this route type ESI and the Ethernet Tag ID are considered to be part of the prefix in the NLRI. Upon a link failure between ToR leaf and end server VTEP withdraws Ethernet Auto-Discovery routes (Type 1) per ES. The Juniper EVPN multi-homing Ethernet Tag value is set to the VLAN ID for ES auto-discovery/ES route types.
Mass Withdrawal - Used for fast convergence during link failure scenarios between leaf devices to the end server using Type 1 EAD/ES routes.
