Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q52-Q57):

NEW QUESTION # 52
Exhibit.

Referring to the exhibit, which statement Is true?

A. A CRB architecture is being used.
B. An OTT architecture is being used.
C. An ERB architecture is being used.
D. A PBB-EVPN architecture is being used.

Answer: C

Explanation:
* Understanding Network Architectures:
* ERB (Edge Routed Bridging) architecture involves routing at the network's edge (leaf nodes), while traffic between leaf nodes is switched. This is commonly used in VXLAN-EVPN setups.
* Analysis of the Exhibit:
* The exhibit shows configurations related to routing instances, VXLAN, and VLANs, with VNIs being used for each VLAN. This setup is characteristic of an ERB architecture where each leaf device handles Layer 3 routing for its connected devices.
Conclusion:
* Option B:Correct-The configuration shown corresponds to an ERB architecture where routing occurs at the network's edge (leaf devices).

NEW QUESTION # 53
Exhibit.

The exhibit shows the truncated output of the show evpn database command.
Given this output, which two statements are correct about the host with MAC address 40:00:dc:01:00:04?
(Choose two.)

A. The host is located on VN110002.
B. The host is assigned IP address 10.4.4.5.
C. The host is originating from an ESI LAG.
D. The host is originating from irb.300.

Answer: B,C

Explanation:
* Understanding the Output:
* The show evpn database command output shows the MAC address, VLAN, active source, timestamp, and IP address associated with various hosts in the EVPN instance.
* Analysis of the MAC Address:
* Option A:The MAC address 40:00:dc:01:00:04 is associated with the IP address 10.4.4.5, as indicated by the output in the IP address column. This confirms that this host has been assigned the IP 10.4.4.5.
* Option D:The active source for the MAC address 40:00:dc:01:00:04 is listed as 00:02:00:00:00:
04:00:04:00:00:04:00:04, which indicates that the host is connected via an ESI (Ethernet Segment Identifier) LAG (Link Aggregation Group). This setup is typicallyused in multi-homing scenarios to provide redundancy and load balancing across multiple physical links.
Conclusion:
* Option A:Correct-The host with MAC 40:00:dc:01:00:04 is assigned IP 10.4.4.5.
* Option D:Correct-The host is originating from an ESI LAG, as indicated by the active source value.

NEW QUESTION # 54
Exhibit.

Referring to the exhibit, why is the active source field blank for the entry that uses the 00:0c:29:e8:b7:39 MAC address?

A. The host for this entry is locally connected to leaf1.
B. This entry is associated with a multicast EVPN route.
C. The ARP lookup for this host has failed.
D. The EVPN route for this host does not have a valid next hop.

Answer: D

Explanation:
In this scenario, the active source field is blank for the MAC address 00:0c:29:e8:b7:39, indicating an issue with how this MAC entry is being processed within the EVPN/VXLAN environment.
Step-by-Step Analysis:
* Understanding the MAC Entry:
* The active source field should normally indicate the source of the route advertisement for a specific MAC address within the EVPN. If it is blank, it suggests that there is a problem with how this entry is being learned or propagated.
* Possible Issues:
* Option A:If the EVPN route for this MAC address does not have a valid next hop, the entry might exist in the MAC table, but it will not have a valid path for forwarding, leading to a blank active source.
* Option B:If the ARP lookup had failed, the entry might not even appear in the MAC table.
However, the entry does exist, suggesting that ARP is not the primary issue here.
* Option C:If the host were locally connected, the active source should reflect a local interface, but the field is blank, ruling out local connection as the cause.
* Option D:Multicast EVPN routes typically do not appear in this manner in the MAC table, and this would not cause the active source to be blank.
Conclusion:The most logical explanation is that the EVPN route for this host exists but does not have a valid next hop, leading to the absence of an active source. This is consistent with how EVPN routing tables work in a VXLAN environment, where the lack of a valid next hop would prevent proper route advertisement and forwarding for the specific MAC address.

NEW QUESTION # 55
Exhibit.

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 export policy is incorrectly configured.
B. EVPN routes cannot have the next hop changed.
C. The vrf-export parameter must be applied.
D. The vpn-apply-export parameter must be applied to this peer.

Answer: D

Explanation:
* Understanding the Configuration:
* The configuration shown in the exhibit involves an EVPN (Ethernet VPN) setup using BGP as the routing protocol. The export policy named CHANGE_NH is applied to the BGP group evpn- peer, which includes a rule to change the next hop for routes that match the policy.
* Issue with Next Hop Not Changing:
* The policy CHANGE_NH is correctly configured to change the next hop to 203.0.113.10 for the matching routes. However, the next hop remains unchanged when advertising EVPN routes to the peer 203.0.113.2.
* Reason for the Issue:
* In Junos OS, when exporting routes for VPNs (including EVPN), the next-hop change defined in a policy will not take effect unless the vpn-apply-export parameter is used inthe BGP configuration. This parameter ensures that the export policy is applied specifically to VPN routes.
* The vpn-apply-export parameter must be included to apply the next-hop change to EVPN routes.
* Correct Answer Explanation:
* D. The vpn-apply-export parameter must be applied to this peer:This is the correct solution because the next hop in EVPN routes won't be altered without this parameter in the BGP configuration. It instructs the BGP process to apply the export policy to the EVPN routes.
Data Center References:
* This behavior is standard in EVPN deployments with Juniper Networks devices, where the export policies applied to VPN routes require explicit invocation using vpn-apply-export to take effect.

NEW QUESTION # 56
A local VTEP has two ECMP paths to a remote VTEP
Which two statements are correctwhen load balancing is enabled in this scenario? (Choose two.)

A. The inner packet fields are used in the hash for load balancing.
B. The source port in the UDP header is used to load balance VXLAN traffic.
C. The inner packet fields are not used in the hash for load balancing.
D. The destination port in the UDP header is used to load balance VXLAN traffic.

Answer: A,B

Explanation:
* Load Balancing in VXLAN:
* VXLAN uses UDP encapsulation to transport Layer 2 frames over an IP network. For load balancing across Equal-Cost Multi-Path (ECMP) links, various fields in the packet can be used to ensure even distribution of traffic.
* Key Load Balancing Fields:
* C. The source port in the UDP header is used to load balance VXLAN traffic:This is correct.
The source UDP port in the VXLAN packet is typically calculated based on a hash of the inner packet's fields. This makes the source port vary between packets, enabling effective load balancing across multiple paths.
* D. The inner packet fields are used in the hash for load balancing:This is also correct. Fields such as the source and destination IP addresses, source and destination MACaddresses, and possibly even higher-layer protocol information from the inner packet can be used to generate the hash that determines the ECMP path.
* Incorrect Statements:
* A. The inner packet fields are not used in the hash for load balancing:This is incorrect as the inner packet fields are indeed critical for generating the hash used in load balancing.
* B. The destination port in the UDP header is used to load balance VXLAN traffic:This is incorrect because the destination UDP port in VXLAN packets is typically fixed (e.g., port 4789 for VXLAN), and therefore cannot be used for effective load balancing.
Data Center References:
* Effective load balancing in VXLAN is crucial for ensuring high throughput and avoiding congestion on specific links. By using a combination of the source UDP port and inner packet fields, the network can distribute traffic evenly across available paths.
