Q: 1
Which OMP route is selected for equal OMP route preference values on WAN Edge routers?
Options
10 comments in the community discussion
1
Makes sense that it's A.
1
I don’t think it’s D. A is right here because when OMP route preferences are the same, Cisco SD-WAN WAN Edge routers use the TLOC preference as the next tie-breaker and pick the one with the higher TLOC value. The lower TLOC might look logical but that’s not how OMP works according to official docs. Makes sense?
Q: 2
Which pathway under Monitor > Network > Select Device is used to verify service insertion configuration?
Options
15 comments in the community discussion
A official Cisco guides and network lab screenshots back this up. Check Monitor section in practice questions to confirm.
C is wrong, A makes sense here. Real Time in Monitor > Network > Select Device shows the current service insertion config, not just logs or events. Verifying live status means you want what's running now, not history. Pretty sure that's Cisco's intent but open to being corrected if someone sees different docs.
Q: 3
Which SD-WAN component is configured to enforce a policy to redirect branch-to-branch traffic toward a network service such as a firewall or IPS?
Options
15 comments in the community discussion
3
Option C
2
Option C Saw similar logic in other SD-WAN practice sets, this matches the policy enforcement role. Clear question!
Q: 4
What is an attribute of TLOC’?
Options
12 comments in the community discussion
2
C or D? Saw a similar question on a practice exam, and "tag" showed up as the key TLOC attribute. Leaning C.
1
C/tag here. The TLOC tuple is color, encap, and tag, not service. Pretty sure this lines up with what I've read in Cisco materials but open to other thoughts if you have lab output showing otherwise.
Q: 5
Where on vManage does an engineer find the details of control node failure?
Options
13 comments in the community discussion
3
Option A is right, you'd check Alarms on vManage for control node failures since that's where system alerts for issues like this are flagged. Events shows more general logs, but Alarms are specific to troubles needing immediate attention. Pretty sure about this, but open if someone disagrees.
1
I always go to Events for stuff like this. B
Q: 6
Which command verifies a policy that has been pushed to the vEdge router?
Options
16 comments in the community discussion
2
What if the question meant verifying on vSmart instead of vEdge? Would D make more sense in that scenario?
2
Makes sense to pick B here if they're asking about policies the vEdge received from vSmart. I think that's what they mean by "pushed" policy, but open to a different read if I'm missing something.
Q: 7
Which two hardware platforms support Cisco IOS XE SD-WAN images'' (Choose two)
Options
8 comments in the community discussion
I think it's A and E. ASR1000 and ISR4000 are the main platforms running IOS XE SD-WAN images. Not totally sure if Cisco's changed naming with ISR9300 (B), but don't think it's officially supported yet. Jump in if anyone saw otherwise.
C/D? If vEdge-1000 is in the mix, it supports SD-WAN but not IOS XE images. ASR9000 (D) is IOS XR only, so really just A and E fit for IOS XE SD-WAN unless Cisco changed something super recently.
Q: 8
Which command displays BFD session summary information per TLOC on vEdge routers?
Options
18 comments in the community discussion
6
Option D had something like this in a mock test before.
1
Probably D for this. The command specifically calls out per TLOC summaries which is what the question asks for.
Q: 9
Refer to the exhibit. CISCO 300-415 question An engineer is troubleshooting a control connection Issue. What does "connect" mean in this how control connections output?
Options
13 comments in the community discussion
4
Makes sense to pick C here. In SD-WAN control connections, "connect" shows the device is still trying to establish the session, not that it's actually up yet. Pretty sure that's what they're looking for, but open to other ideas!
1
C tbh. "Connect" here means the device is still trying to form the control connection, not fully up yet. Full connection would be D but that's only with "connected" or "up" statuses. Anyone disagree?
Q: 10
What are the two protocols redistributed into OMP? (Choose two.)
Options
15 comments in the community discussion
1
Option A and E. OSPF and EIGRP are redistributed into OMP with IOS XE SD-WAN, not RIP (B). Saw similar confusion before, but B is a trap as that's only for vEdge platforms. Pretty sure about this, but open if anyone has solid docs showing otherwise.
1
B and E
Q: 11
Which logs verify when a device was upgraded?
Options
2 comments in the community discussion
1
Seen similar practice questions, usually audit logs are the way to check upgrades. A
Q: 12
DRAG DROP Drag and drop the steps from the left Into the order on the right to delete a software image for a WAN Edge router starting with Maintenance > Software Upgrade > Device list on vManage. CISCO 300-415 question
Your Answer
3 comments in the community discussion
1
Deactivation is the key here. Not B, D. I've seen similar questions and deleting before deactivating is a common trap.
1
Its D, just remember you can't remove the image unless it's deactivated on the device. Seen this tripping people up in practice labs.
Q: 13
How is an event monitored and reported for an individual device in the overlay network at site ID:S4300T6E43F36?
Options
3 comments in the community discussion
1
A imo, but does the question want all event types or just critical alarms? That could flip it to C. Official guide probably clarifies this process for vManage notifications.
Q: 14
When software is upgraded on a vManage NMS, which two image-adding options store images in a local vManage software repository? (Choose two.)
Options
2 comments in the community discussion
Maybe A and B, since SNMP and SMTP can both transfer files if configured that way.
Q: 15
Which Cisco SD-WAN WAN Edge platform supports LTE and Wi-Fi?
Options
3 comments in the community discussion
D ISR 1101 supports built-in LTE and Wi-Fi if you add the right modules. The others don’t support both by default. Pretty sure about this based on model specs, unless Cisco changed something recently.
Q: 16
An engineer is troubleshooting a vEdge router and identifies a “DCONFAIL – DTLS connection failure” message. What is the problem?
Options
2 comments in the community discussion
BNice straightforward question, reminds me of similar ones in exam reports.
Q: 17
What happens if the intelligent proxy is unreachable in the Cisco SD-WAN network?
Options
2 comments in the community discussion
1
A, Clear and straightforward, similar question popped up in practice sets.
Q: 18
Which configuration changes the packet loss priority from low to highly? A) CISCO 300-415 question B) CISCO 300-415 question C) CISCO 300-415 question D) CISCO 300-415 question

Option B matches what I've seen in practice labs. Super clear screenshot choices too.
Q: 19
An engineer must configure the SD-WAN Edge router to identify DSCP 26 traffic coming from the router's local site and then change the DSCP value to DSCP 18 before sending it over to the SD-WAN fabric. What are the two ways to create the required configuration? (Choose two). CISCO 300-415 question CISCO 300-415 question
Options

2
A and B, both methods work to match and mark DSCP as required. Super clear question!
1
A and B. C is tempting but doesn't actually rewrite the DSCP, just matches. Seen this setup in labs and practice, pretty sure A/B is what Cisco wants here.
Q: 20
Which two actions are necessary to set the Controller Certificate Authorization mode to indicate a root certificate? (Choose two)
Options
2 comments in the community discussion
1
Nice, this is clear. For setting a root cert in SD-WAN, you need to upload the SSL cert to vManage and pick a private CA rather than public. So, C and D.
