NEW QUESTION # 31
In Campus EVPN-VXLAN deployments, multipath is used to: (Select two)
- A. Enhance load balancing across multiple paths
- B. Provide a single path for data flow
- C. Simplify network management
- D. Increase network redundancy and bandwidth
Answer: A,D
NEW QUESTION # 32
You have two sites connected to an EVPN network. Each site is using the172.16.1.0/24network for its own respective site.
How does EVPN prevent overlap in this scenario?
- A. It uses a Layer 2 gateway.
- B. It uses an Ethernet segment identifier (ESI).
- C. It elects a designated forwarder.
- D. It uses a route distinguisher.
Answer: D
Explanation:
EVPN, when used with VXLAN, leveragesBGP MPLS/VXLAN control plane mechanisms. To prevent overlapping IP prefixes between different tenants or sites, EVPN uses aRoute Distinguisher (RD).
"In EVPN-VXLAN, the route distinguisher (RD) makes routes unique when overlapping IP prefixes or MAC addresses are advertised between multiple tenants or sites." Option A(designated forwarder) applies to multi-homing in EVPN, not prefix uniqueness.
Option B(Layer 2 gateway) does not prevent IP overlap; it bridges VLANs.
Option D(ESI) is used for identifying multi-homed Ethernet segments, not to differentiate overlapping subnets.
Option C(Route Distinguisher) is correct, as it uniquely identifies routes even if the IP addresses are the same across sites.

NEW QUESTION # 34
Click the Exhibit button.
What does the exhibit show as part of the switching upgrade process?
- A. The switch model is a EX2300-C-12T.
- B. Multiple switches will be upgraded.
- C. The previous software version was 18.3R1.8.
- D. The switch will reboot after the upgrade.
Answer: D
Explanation:
According to the Juniper Mist dashboard's firmware management interface shown in the exhibit, several key details of the switch upgrade process are visible. The "Upgrade switch firmware" dialog box is a standard component of Juniper Mist Wired Assurance used to manage Junos OS updates across the fabric.
The correct statement is that the switch will reboot after the upgrade. This is explicitly confirmed by the checkbox labeled "Reboot switch after image copy," which is currently selected in the exhibit. In Juniper's cloud-managed workflow, once the new software image is successfully transferred from the Mist cloud to the switch's local storage, the system requires a reboot to initialize the new Junos OS kernel and complete the installation process5. While some platforms support non-disruptive upgrades, the standard procedure for EX- series switches in a standalone or Virtual Chassis configuration typically involves a scheduled reboot to ensure the new version is correctly applied.
The other options are incorrect based on the visual evidence provided in the exhibit.
* Option A: The exhibit clearly identifies the "Switch Model" as an EX2300-C-12P (the 'P' designating PoE support), not an EX2300-C-12T88.
* Option C: The dialog box explicitly states "Total Switches selected to upgrade: 1," confirming this is a single-device operation rather than a bulk upgrade.
* Option D: The "Upgrade to Version" field is set to 19.3R1.8, which indicates the target version, not the previous version10101010.
By providing these granular controls, Juniper Mist allows administrators to maintain strict version compliance across the site while choosing whether to immediately reboot or stage the image for a later maintenance window.
NEW QUESTION # 35

Answer: A,D
NEW QUESTION # 36
You must ensure that routes within a multitenant domain remain unique when advertised in a service provider network. Which EVPN functionality will accomplish this task?
- A. VRF export policy
- B. route distinguisher
- C. Ethernet segment identifier (ESI)
- D. route targets
Answer: B
Explanation:
According to Juniper documentation, a route distinguisher (RD) is a critical address qualifier used to ensure that network layer reachability information (NLRI) remains unique within a Multiprotocol BGP (MP-BGP) control plane, especially in multitenant environments. In a service provider network, different tenants may use identical, overlapping private IP address spaces (such as 192.168.1.0/24). If these routes were advertised without a qualifier, BGP-which typically only considers the IP prefix-would treat them as the same route and potentially overwrite one with the other based on standard BGP best-path selection.
The route distinguisher solves this by prepending an 8-byte field to the tenant's IP address, effectively transforming a 32-bit IPv4 prefix into a unique 96-bit VPN-IPv4 address. This 8-byte value is typically configured in formats such as as-number:number or ip-address:number. Because the resulting VPN-IPv4 prefix is unique to that specific routing instance, the service provider's BGP infrastructure can carry and distinguish between overlapping routes from multiple customers simultaneously.
It is important to differentiate the RD from a route target (RT). While the RD's sole purpose is to provide uniqueness so that routes are not discarded or overwritten, the route target is an extended community attribute used to control the import and export of these routes into the correct virtual routing and forwarding (VRF) tables on remote PE routers. In Juniper's Junos OS, each routing instance of type vrf or evpn must have a unique RD associated with it; failing to configure a unique RD or attempting to use the same RD across different instances will result in a configuration commit failure. This fundamental separation of "making routes unique" (RD) and "directing routes to the right place" (RT) allows for the scalable, isolated multitenancy required in modern EVPN-VXLAN campus and data center fabrics.
NEW QUESTION # 37
You have deployed your switches and need to provide aunique hostnameon each switch.
Which Mist dashboard option allows you to accomplish this task?
- A. Individual switch configuration
- B. Site switch configuration
- C. Device profiles
- D. Organization switch template
Answer: A
Explanation:
In Juniper Mist Cloud, there are multiple configuration scopes:
Organization-level templatesapply globally.
Site-level configurationapplies across all devices in a site.
Individual switch configurationis used to define unique, device-specific attributes such ashostname, management IP, or local overrides.
"Templates and site-level configuration ensure consistency across devices, whileindividual switch configuration is used to assign unique values such as hostnames." Option A:Incorrect - org templates define common config, not hostnames.
Option B:Incorrect - site configs are shared across all switches in the site.
Option D:Incorrect - device profiles apply settings like port policies or authentication, not hostnames.
Option C:Correct -individual switch configurationis the correct place to assign hostnames uniquely per device.

NEW QUESTION # 39
You are planning to deploy a fabric in your large campus with 10,000+ users. You will have both Layer 2 and Layer 3 devices that connect to your access switches. In this scenario, which campus architecture should you use?
- A. core-distribution with edge-routed bridging (ERB)
- B. core-distribution with centrally-routed bridging (CRB)
- C. IP Clos
- D. EVPN multihoming
Answer: C
Explanation:
According to Juniper's Validated Designs (JVD) for campus fabrics, the Campus Fabric IP Clos (often referred to as a 5-stage Clos) is the architecture specifically engineered for high-scale environments supporting 10,000+ users. This design is characterized by extending the EVPN control plane and VXLAN data plane all the way to the access layer. By terminating VXLAN tunnels at the access switch-functioning as a Virtual Tunnel Endpoint (VTEP)-the network can seamlessly support both Layer 2 and Layer 3 devices directly at the edge of the fabric.
The primary driver for choosing IP Clos in large-scale deployments is its superior scalability. In this model, the core switches are shielded from the massive table sizes required to learn thousands of individual endpoint MAC and IP addresses. Instead, core devices only need to maintain reachability to the loopback addresses of the access layer switches. This reduction in the "flood and learn" pressure on the core is critical as the number of endpoints grows, ensuring that the core can scale far into the future with predictable growth.
Additionally, the IP Clos architecture provides the most flexible environment for microsegmentation using Group-Based Policies (GBP) and macrosegmentation using Virtual Routing and Forwarding (VRF) instances. Since routing occurs at the access device, "east-west" traffic between local endpoints remains efficient and does not need to traverse the distribution or core tiers. While EVPN Multihoming and Core- Distribution (CRB/ERB) models are effective for smaller sites or brownfield environments where access switches are legacy Layer 2-only devices, only the IP Clos architecture provides the end-to-end VXLAN capability required for high-density, future-proof campus fabrics.
NEW QUESTION # 40
You must move from acampus fabric core-distribution centrally-routed bridging (CRB)network to anedge- routed bridging (ERB)network.
In this scenario, where does thegateway for the networkmove?
- A. from core to distribution
- B. from distribution to core
- C. from distribution to access
- D. from access to distribution
Answer: C
Explanation:
In Juniper Mist campus fabric architectures, thelocation of the Layer 3 gateway (IRB interface) differentiatescentrally-routed bridging (CRB)fromedge-routed bridging (ERB):
InCRB, thegateway resides at the core layer- routing occurs centrally, and access/distribution layers perform Layer 2 bridging.
InERB, thegateway moves to the edge (distribution layer), enabling routing to occur closer to endpoints, improving performance and scalability.
"In a centrally-routed bridging (CRB) topology, Layer 3 gateways reside at the core. When transitioning to an edge-routed bridging (ERB) design, the Layer 3 gateways are moved to the distribution layer, closer to the access switches and clients." Therefore, when moving from acore-distribution CRBto anERBmodel, thegateway moves from the distribution to the access layerin campus terms (edge = access).
Option A:Incorrect - ERB gateways are not at the distribution layer only.
Option B:Incorrect - opposite direction.
Option C:Correct- the gateway movesfrom distribution to access (edge).
Option D:Incorrect - this describes CRB, not ERB.
