You have configured a static route to be used for management traffic. You want to ensure that this route is not propagated to other routers. In this scenario, which parameter would you add to this route configuration?
Answer : C
In Junos, static routes are eligible to be exported into dynamic routing protocols if you configure an export policy that matches them. For management-only routes, especially default routes or specific management subnets used for out-of-band access, you often want to ensure they never leak into the production routing domain. The no-readvertise parameter is designed for this purpose. When you mark a static route as no-readvertise, Junos flags it so other routing protocols do not export or readvertise it, even if an export policy would otherwise match it. This helps keep the management plane isolated from the data plane and prevents accidental propagation of management reachability into the fabric underlay or overlay.
The reject and discard options control how packets are handled if they match the route, not whether the route is eligible to be exported. Preference 255 changes the route's selection priority relative to other routes, but it does not prevent export. Therefore, no-readvertise is the correct configuration knob when the explicit goal is to prevent propagation of a management static route to other routers.
Referring to the exhibit, what is the cause of the problem?
Answer : C
The BGP session in the exhibit shows the state as Connect, which indicates that the TCP session between the BGP peers has not been fully established.
Step-by-Step Breakdown:
BGP State 'Connect':
The Connect state is the second stage in the BGP finite state machine (FSM). At this stage, BGP is trying to establish a TCP session with the peer, but the session has not yet been successfully established.
A successful TCP three-way handshake (SYN, SYN-ACK, ACK) is required before BGP can progress to the OpenSent state, where the peers exchange BGP Open messages.
Possible Causes:
A firewall blocking TCP port 179.
Incorrect IP addresses or network connectivity issues between the BGP peers.
Juniper Reference:
BGP Troubleshooting: In Junos, if a BGP session is stuck in the Connect state, the issue is likely due to a failure in establishing the underlying TCP connection.
Which statement about the qualified next-hop feature is correct when configuring a static route?
Answer : A
Qualified next hop is the Junos mechanism that lets you configure more than one next hop for the same static route and control which one is preferred. This is most commonly used to build primary and backup forwarding behavior with deterministic selection. You configure a primary next hop and then add one or more qualified next hops with a different preference value. The route installs the best, lowest preference next hop as active, while keeping the alternate next hop available as standby. If the primary next hop becomes unusable, Junos can switch to the qualified next hop so traffic continues to flow.
This approach is widely used in data center edge and services routing, for example toward management networks, service appliances, or external gateways where you want a static default or summary route with predictable failover. It is not the same as resolving a non-directly-connected next hop. That scenario is handled by recursive resolution behavior, not by qualification. Qualified next hop also does not depend on any specific routing protocol, and it is not limited to link-state environments.
Finally, qualified next hop does not rely on sending pings to test reachability. Health tracking can be achieved through other mechanisms such as interface state, next hop resolution changes, or integration with failure detection features, but the qualified next hop feature itself is about preference-ranked redundancy for static routes.
What are two advantages of spine and leaf architectures compared to legacy architectures within a data center? Choose two.
Answer : B, C
Spine and leaf architectures improve data center scalability by using a consistent, modular building block. When you need more server ports, you add leaf switches. When you need more fabric capacity, you add spine switches. This horizontal growth model avoids the limitations of traditional three-tier designs that often require larger aggregation devices or complex expansion. Because each leaf connects to every spine, the fabric naturally provides many parallel paths and can use equal-cost multipath forwarding across all uplinks. These properties deliver better scaling characteristics in both bandwidth and port count, which is why option B is correct.
Option C is also correct because spine and leaf fabrics provide low and predictable hop counts. Traffic between endpoints on different leaves typically crosses the fabric with a consistent number of hops, usually one spine hop in a two-tier fabric. This predictability reduces latency variance and improves application performance, especially for east-west traffic patterns common to distributed systems, storage, and microservices. Predictable paths also simplify troubleshooting and capacity planning.
Container and hypervisor management is primarily an orchestration and operations topic rather than a direct network architecture advantage. Finally, making all broadcast domains reachable is not an inherent benefit; modern data centers usually limit Layer 2 flooding domains and prefer routed underlays with overlays for segmentation, rather than expanding broadcast reachability everywhere.
Which BGP attribute is used to prevent routing loops in a network?
Answer : D
BGP prevents inter-domain routing loops primarily through the AS_PATH attribute. Each time a route advertisement crosses an autonomous system boundary, the advertising router prepends its own AS number to the AS_PATH before sending the route onward. When a router receives a BGP update, it can inspect the AS_PATH and reject routes that already contain its own AS number. This simple rule blocks the route from circulating back into the same AS, which is the fundamental loop prevention behavior in BGP.
In data center IP fabrics that use EBGP for the underlay, AS_PATH still plays an important role even though private AS numbers are used. The fabric can be designed so that leaf and spine devices are in distinct private ASs or use structured AS assignment, and AS_PATH tracking ensures clean propagation and helps operators understand where a route has traveled. It also supports policy decisions, such as preferring shorter paths or applying policy based on specific AS sequences.
The other attributes serve different purposes. MED influences inbound path selection into an AS, LOCAL_PREF is used within an AS to influence outbound selection, and NEXT_HOP indicates the forwarding next hop and is validated for reachability. None of those attributes provide the explicit ''contains my AS'' loop detection that AS_PATH does.
