NEW QUESTION # 25
Exhibit.
Referring to the exhibit, which statement is correct?
- A. The remote VTEP is not responding.
- B. The MAC address is known but not reachable by the remote VTEP
- C. VNI 100 is not configured on the remote VTEP.
- D. The MAC address is unknown and not in the forwarding table of the remote VTEP.
Answer: D
Explanation:
* Analyzing the Exhibit Output:
* The command ping overlay tunnel-type vxlan is used to test the VXLAN tunnel between two VTEPs (VXLAN Tunnel Endpoints). The output shows a warning about missing hash parameters, but more importantly, it displays the result: End-System Not Present.
* Understanding the Response:
* The message End-System Not Present indicates that the remote VTEP (192.168.2.20) did not find the MAC address 00:00:5E:00:53:CC in its forwarding table. This typically means that the MAC address is unknown to the remote VTEP, and as a result, it could not forward the packet to the intended destination.
Conclusion:
* Option B:Correct-The MAC address is unknown and is not in the forwarding table of the remote VTEP, which is why the system reports that the "End-System" is not present.
NEW QUESTION # 26

What are two ways in which an EVPN-signaled VXLAN is different from a multicast-signaled VXLAN? (Choose two.)
- A. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP.
- B. An EVPN-signaled VXLAN features slower and more complete convergence.
- C. An EVPN-signaled VXLAN is less resource intensive.
- D. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using IS-IS.
Answer: A,C
Explanation:
An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP
EVPN uses BGP control plane to advertise MAC-to-VTEP mappings and perform VTEP autodiscovery, removing the need for multicast in the underlay.
An EVPN-signaled VXLAN is less resource intensive
Unlike multicast VXLAN, EVPN doesn't rely on flooding unknown traffic via multicast groups in the underlay, reducing bandwidth and CPU usage.
NEW QUESTION # 31
Given the configuration shown in the exhibit, why has the next hop remained the same for the EVPN routes advertised to the peer 203.0.113.2?
- A. The vpn-apply-export parameter must be applied to this peer.
- B. EVPN routes cannot have the next hop changed.
- C. The vrf-export parameter must be applied.
- D. The export policy is incorrectly configured.
Answer: A
Explanation:
The vpn-apply-export parameter must be applied to this peer: In the given configuration, the policy statement CHANGE_NHis defined to change the next-hop IP for routes. However, the vpn- apply-exportparameter is missing, which is necessary for applying export policies to routes associated with a particular VPN. Without this parameter, the export policy does not apply to the EVPN routes, and thus the next-hop remains unchanged.

- D. Devices in irb.400 (vlan 400) are not able to communicate directly with devices in routing instance Customer A.
Answer: C,D
Explanation:
* Understanding the Configuration:
* The exhibit shows configurations for two VRFs (Customer_A and Customer_B) with specific VLANs and VNIs assigned. Each VRF has interfaces (IRBs) associated with particular VLANs.
* Communication Between VLANs and Routing Instances:
* Option B:VLAN 400 (irb.400) is part of Customer_B, and there is no direct connection or routing between Customer_A and Customer_B in the configuration provided. Therefore, devices in irb.400 cannot communicate directly with devices in the Customer_A routing instance.
* Option D:Since irb.400 (VLAN 400) and irb.800 (VLAN 800) are part of the same routing instance (Customer_B), they can communicate over the fabric using VXLAN encapsulation.
Conclusion:
* Option B:Correct-There is no direct communication between devices in irb.400 (Customer_B) and routing instance Customer_A.
* Option D:Correct-Devices in VLAN 400 and VLAN 800 can communicate within the Customer_B routing instance over the fabric.

Option D: Since irb.400 (VLAN 400) and irb.800 (VLAN 800) are part of the same routing instance (Customer_B), they can communicate over the fabric using VXLAN encapsulation.
NEW QUESTION # 34
You are asked to identify microburst traffic occurring in the network leading lo packet drops in your data center switches Which two tools would be used in this scenario? (Choose two.)
- A. Traceoptions
- B. syslog
- C. port buffer monitoring
- D. port mirroring
Answer: C,D
Explanation:
* Identifying Microburst Traffic:
* Microbursts are short spikes in network traffic that can overwhelm buffers and cause packet drops. Detecting and analyzing microbursts is crucial for understanding where packet loss might be occurring in a data center network.
* Port Buffer Monitoring:
* Port Buffer Monitoring:This tool specifically tracks the usage of switch buffers, helping to identify when microbursts are causing buffers to overflow, leading to packet drops.
* Port Mirroring:
* Port Mirroring:This tool allows you to monitor real-time traffic on a specific port by copying the traffic to another port where it can be analyzed, often with a packet analyzer. While port mirroring doesn't directly detect microbursts, it helps capture traffic patterns that can indicate microbursts.
Conclusion:
* Option C:Correct-Port buffer monitoring directly identifies buffer overflows caused by microbursts.
* Option A:Correct-Port mirroring allows for the detailed capture and analysis of traffic patterns, which can reveal microburst behavior.
Options B(Traceoptions) andD(Syslog) are less effective in identifying microburst traffic. Traceoptions focus on control plane traffic debugging, and Syslog is more about logging system events than detecting high- frequency traffic spikes.

NEW QUESTION # 36
You are asked to automatically provision new Juniper Networks devices in your network with minimal manual intervention Before you begin, which two statements are correct? (Choose two.)
- A. You must have an NTP server to perform time synchronization.
- B. You must have a DHCP server that provides the location of the software image and configuration files.
- C. You must have a file server that stores software image and configuration files.
- D. You must have a system log (syslog) server to manage system log messages and alerts.
Answer: B,C
Explanation:
You must have a DHCP server that provides the location of the software image and configuration files: This is necessary because DHCP is typically used in automated provisioning processes to provide the device with its IP address, gateway, and important information like the location of the configuration and software image files. These files are crucial for the device to properly boot and configure itself.
You must have a file server that stores software image and configuration files: A file server (usually TFTP or HTTP server) is required to store the necessary software image and configuration files for the Juniper device. These files are fetched during the provisioning process to set up the device.
NEW QUESTION # 37
You are preparing an sFlow monitoring system configuration. In this scenario, what Information will be included in the datagram sent to the sFlow collector? (Choose two.)
- A. the CRC from the sampled packet
- B. the source and destination VLAN for sampled packets
- C. the sending device's serial number
- D. the interlace through which the packets entered the agent
Answer: B,D
Explanation:
sFlow is a packet sampling technology used to monitor traffic in a network. It sends sampled packet data and interface counters to an sFlow collector, which analyzes the traffic patterns.
Option A: The datagram sent to the sFlow collector includes information about the interface through which the packets entered the agent (the switch or router). This is crucial for understanding where in the network the traffic was captured.
Option D: sFlow datagrams also include the source and destination VLAN for the sampled packets. This allows for detailed analysis of the traffic flow within different VLANs.

* Key Requirements for ZTP:
* A. DHCP Server:A DHCP server is crucial for ZTP as it provides the necessary information to new devices, such as the IP address, the location of the software image, and configuration files.
* D. File Server:The file server is where the software image and configuration files are stored. The device downloads these files during the provisioning process.
* Incorrect Options:
* B. Syslog Server:While a syslog server is important for logging and monitoring, it is not a requirement for the initial provisioning process.
* C. NTP Server:An NTP server is used for time synchronization, which is essential for accurate logging and operation but not specifically required for ZTP.
Data Center References:
* ZTP simplifies the deployment process by automating the initial configuration steps, relying heavily on DHCP for communication and a file server for delivering the necessary configuration and software.
NEW QUESTION # 39
Exhibit.
Referring to the exhibit, the spinel device has an underlay BGP group that is configured to peer with its neighbors' directly connected interfaces. Which two statements are true in this scenario? (Choose two.)
- A. Load balancing for the underlay is not configured correctly.
- B. The multihop statement is required to establish the underlay BGP sessions.
- C. The multihop statement is not required to establish the underlay BGP sessions.
- D. Load balancing for the underlay is configured correctly.
Answer: C,D
Explanation:
* Understanding BGP Configuration in the Exhibit:
* The exhibit shows a BGP configuration on spine1 with a group named underlay, configured to peer with directly connected interfaces of other devices in the network.
* Multipath multiple-as:This statement allows the router to install multiple paths in the routing table for routes learned from different ASes, facilitating load balancing.
* Key Statements:
* A. The multihop statement is not required to establish the underlay BGP sessions:In this case, the BGP peers are directly connected (as indicated by their neighbor IP addresses), so the multihop statement is unnecessary. Multihop is typically used when BGP peers are not directly connected and packets need to traverse multiple hops.
* D. Load balancing for the underlay is configured correctly:The multipath { multiple-as; } statement in the configuration enables load balancing across multiple paths from different autonomous systems, which is appropriate for underlay networks in data center fabrics.
* Incorrect Statements:
* C. The multihop statement is required to establish the underlay BGP sessions:This is incorrect because the peers are directly connected, making the multihop statement unnecessary.
* B. Load balancing for the underlay is not configured correctly:This is incorrect because the configuration includes the necessary multipath settings for load balancing.
Data Center References:
* BGP configurations in EVPN-VXLAN underlay networks are crucial for ensuring redundancy, load balancing, and efficient route propagation across the data center fabric.
NEW QUESTION # 40
Why is a designated forwarder required in a multihomed CE-to-PE VXLAN environment using EVPN signalling?
- A. The designated forwarder is required to prevent a traffic storm from being received on multihomed hosts.
- B. The designated forwarder is required to prevent duplicate packets from being received on multihomed hosts.
- C. The designated forwarder is required to prevent flooding of MAC addresses to multihomed hosts.
- D. The designated forwarder is required to prevent packets from looping between the PEs.
Answer: B
Explanation:
The designated forwarder is required to prevent duplicate packets from being received on multihomed hosts: In a multihomed CE-to-PE VXLAN environment using EVPN signaling, a host may be connected to more than one PE. Without a designated forwarder, both PEs could forward the same broadcast, multicast, or unicast traffic to the multihomed host, leading to duplicate packets. The designated forwarder ensures that only one PE forwards traffic to the host, preventing this issue.
NEW QUESTION # 41
Which two statements are true about a pure IP fabric? (Choose two.)
- A. Devices in an IP fabric function as Layer 3 routers.
- B. An IP fabric supports Layer 2 VLANs.
- C. An IP fabric does not support Layer 2 protocols.
- D. Devices in an IP fabric must be connected to a fabric controller.
Answer: A,C
Explanation:
An IP fabric does not support Layer 2 protocols: A pure IP fabric is designed to work primarily at Layer 3 and does not require Layer 2 protocols like spanning tree or VLANs for operation. It focuses on IP-based routing and forwarding, and Layer 2 protocols are not typically used within the fabric itself.
Devices in an IP fabric function as Layer 3 routers: In a pure IP fabric, devices (typically leaf and spine switches) operate primarily as Layer 3 routers. They are responsible for routing IP traffic across the fabric, with VXLAN or other tunneling technologies used for overlay and encapsulation.
NEW QUESTION # 42
Exhibit.
Both DC and DC2 ate using EVPN-VXLAN technology deployed using an ERB architecture. A server on the Red VLAN must communicate with a server on the Green VLAN. The Blue VLAN in DC and DC2 needs to be the same VLAN.
Which statement is correct in this scenario?
- A. A lean super spine device must be added to DC and DC2; all VLANs must be stretched to the lean super spine device and the lean super spine devices must stitch all the VLANs together.
- B. An interconnect is required between the four SRX Series devices; the Blue VLAN must be stretched and a transit VNI must be added for the Red and Green VLANs.
- C. The eight spine devices must be configured as border spine devices; a full mush interconnect must exist between all eight spine devices and the Blue VLAN must be stitched together
- D. An interconnect is required between four leaf devices in the services blocks; the Red VLAN and the Green VLAN must be stitched and the Blue VLAN must be stretched.
Answer: B
Explanation:
* ERB Architecture in EVPN-VXLAN:
* ERB (Edge Routed Bridging) architecture is commonly used in data center networks where routing decisions are made at the network edge (leaf or border devices), while bridging (Layer 2 forwarding) is extended across the fabric. This architecture allows for efficient L3 routing while still enabling L2 services like VLANs to span across multiple locations.
* VLAN and VNI Configuration:
* The scenario specifies that a server on the Red VLAN needs to communicate with a server on the Green VLAN. Since these VLANs are in different data centers (DC and DC2), and given the use of EVPN-VXLAN, the communication between these VLANs will require atransit VNI(Virtual Network Identifier). This transit VNI will allow traffic to traverse the VXLAN tunnel across the DCI (Data Center Interconnect).
* Interconnect between SRX Series Devices:
* The exhibit shows SRX Series Chassis Clusters used as service devices (likely for firewalling or other security services). These devices need to be interconnected between the two data centers to ensure that VLANs can communicate effectively. The Blue VLAN needs to be stretched between DC and DC2 to maintain the same Layer 2 domain across both data centers.
Conclusion:
* Option B:Correct-Interconnecting the SRX Series devices will ensure the necessary service chaining, while stretching the Blue VLAN and adding a transit VNI for the Red and Green VLANs will enable the required communication across the data centers.
NEW QUESTION # 43
Which two statements are true about EVPN routes for Data Center Interconnect? (Choose two.)
- A. Type 5 EVPN routes do not require a VXLAN tunnel to the protocol next hop.
- B. Type 2 EVPN routes do not require a VXLAN tunnel to the protocol next hop.
- C. Type 5 EVPN routes require a VXLAN tunnel to the protocol next hop.
- D. Type 2 EVPN routes require a VXLAN tunnel to the protocol next hop.
Answer: A,B
Explanation:
* Type 2 EVPN Routes:
* Type 2 routesadvertise MAC addresses within an EVPN instance and are used primarily for Layer 2 bridging. These routes do not require a VXLAN tunnel to the protocol next hop because they operate within the same Layer 2 domain.
* Type 5 EVPN Routes:
* Type 5 routesare used to advertise IP prefixes (Layer 3 routes) within EVPN. Similar to Type 2 routes, they do not require a VXLAN tunnel to the protocol next hop because they represent L3 routes, which are managed at the routing layer without the need for VXLAN encapsulation.
Conclusion:
* Option B:Correct-Type 2 routes do not need a VXLAN tunnel to the next hop, as they are used for Layer 2.
* Option D:Correct-Type 5 routes also do not need a VXLAN tunnel because they operate at Layer 3, handling IP prefixes.

Juniper Networks' best practices recommend enabling ETS on interfaces connecting to GPU servers to ensure proper bandwidth allocation and prevent congestion.
NEW QUESTION # 46
Exhibit.
Host A is connected to vlan 100 on lead. Host B is connected to vlan 200 on leaf1. Host A and Host B ate unable to communicate. You have reviewed the touting and your hosts have the correct default route (.1) Referring to the exhibit, which two commands will solve the problem? (Choose two.)
- A. delete vlans vn200 13-interface irb.200
- B. set vlans vn10013-interface irb.100
- C. set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10
- D. set interfaces irb unit 100 family inet address 192-168.100.1
Answer: B,C
Explanation:
In the provided network configuration, Host A is in VLAN 100 and Host B is in VLAN 200. The issue arises because these two hosts are unable to communicate, which indicates that either the interfaces are not properly linked to their respective VLANs, or there is a missing static route required for inter-VLAN routing.
Step-by-Step Analysis:
* VLAN Assignment:
* The exhibit shows that irb.200 is correctly associated with VLAN 200 in the configuration.
However, there is no corresponding irb.100 for VLAN 100. Without irb.100, the network lacks the logical interface to handle routing for VLAN 100. Thus, adding irb.100 to VLAN 100 is necessary.
Command to solve this:
set vlans vn100 13-interface irb.100
* Static Route Configuration:
* For inter-VLAN routing to occur, a static route needs to be configured that allows traffic to pass between different subnets (in this case, between VLAN 100 and VLAN 200). The command set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10 would add a static route that directs all traffic from VLAN 100 to the correct gateway (192.168.200.10), which is necessary to route traffic between the two VLANs.
Command to solve this:
set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10
Explanation of Incorrect Options:
* Option A (delete vlans vn200 13-interface irb.200): This would remove the logical interface associated with VLAN 200, which is not desired because we need VLAN 200 to remain active and properly routed.
* Option B (set interfaces irb unit 100 family inet address 192-168.100.1): This command would incorrectly assign an IP address that does not correspond with the subnet of VLAN 100 (192.168.200.1
/24). This could create a misconfiguration, leading to routing issues.
Data Center References:
For a Data Center, proper VLAN management and static routing are crucial for ensuring that different network segments can communicate effectively, especially when dealing with separated subnets or zones like in different VLANs. This aligns with best practices in DCIM (Data Center InfrastructureManagement) which stress the importance of proper network configuration to avoid downtime and ensure seamless communication between all critical IT infrastructure components.
Ensuring that the correct interfaces are associated with the correct VLANs and having the proper static routes in place are both essential steps in maintaining a robust and reliable data center network.
This detailed analysis reflects best practices as noted in standard data center design and network configuration guides.
NEW QUESTION # 47
You are deploying an IP fabric using EBGP and notice that your leaf devices are advertising and receiving all the routes. However, the routes are not installed in the routing table and are marked as hidden.
Which two statements describe how to solve the issue? (Choose two.)
- A. You need to configure multipath multiple-as.
- B. You need to configure as-override.
- C. You need to configure loops 2.
- D. You need to configure a next-hop self policy.
Answer: C,D
Explanation:
You need to configure a next-hop self policy: When using EBGP, the next-hop IP address in the routing advertisements might not be reachable from the receiving device, causing the routes to be marked as hidden. By configuring the next-hop-selfpolicy, the leaf devices will change the next-hop IP to their own IP address for the routes they advertise, making them reachable within the fabric and allowing the routes to be installed in the routing table.
You need to configure loops 2: When all leaves share the same AS (common-AS design), BGP loop prevention drops routes learned from the same AS. Configuring loops 2 allows the leaf to accept routes with its own AS in the path twice, which is needed in an eBGP IP fabric with repeated AS numbers.
