Cisco 300-440 (ENCC) Sample Questions:

01. You are handed two tunnels to triage. Tunnel A: the peer never responds, no security association of any kind exists, and negotiation attempts time out. Tunnel B: an IKE SA is established and holds steady, but no data flows and no IPsec SA appears. Both peers are reachable by ping.
Which pairing correctly isolates the fault domain for each tunnel?
a) Tunnel A is a Phase 1 failure; Tunnel B is a Phase 2 failure.
b) Both tunnels are Phase 1 failures and the difference between them is only cosmetic reporting.
c) Both tunnels are Phase 2 failures caused by traffic-selector mismatches on the child SA.
d) Tunnel A is a Phase 2 failure while Tunnel B is a Phase 1 failure, the reverse of the actual signatures.
 
02. An engineer is triaging an SD-WAN branch and wants to determine whether a reachability problem is a control-plane issue or a data-plane issue before looking at policy. A branch reports it cannot pass traffic to any other site at all.
Which single check most directly distinguishes a control-plane problem from a data-plane problem?
a) Whether the device certificate on the WAN Edge has expired or been revoked.
b) Whether the branch device happens to be positioned behind a NAT device on its transport.
c) Whether the branch's centralized control policy has an accept action configured for the specific destination prefix in question.
d) Whether the control connections to the controllers are up versus whether the data-plane tunnels and BFD are up.
 
03. A branch must send its business-critical application over a transport path that meets a loss/latency/jitter service-level agreement, falling back to a secondary path only when the primary violates the SLA.
Which policy achieves this application-aware routing behavior?
a) A centralized control policy that filters which routes and TLOCs vSmart advertises to each site
b) A centralized data policy implementing app-aware routing to an SLA class
c) A localized QoS policy on the WAN Edge egress interface
d) A localized ACL applied inbound on the service-side interface
 
04. Two branch WAN Edge routers have healthy control connections to all controllers and their OMP peering is up. However, no data traffic passes between them, and the tunnel between their public-internet TLOCs is not usable. Both branches sit behind internet firewalls. The control connections use the orchestrator on a permitted port, but the site-to-site tunnel between the two TLOCs never becomes usable.
Which cause best explains why the tunnel between the TLOCs is down while control connections remain healthy?
a) The branch firewalls permit the controller traffic but block the UDP ports the data-plane tunnel and its BFD session use.
b) The organization name is mismatched between the two branch devices, which is blocking their tunnel from forming.
c) An application-aware routing policy is holding the branch-to-branch traffic in a backup SLA class and away from the tunnel.
d) A centralized control policy is filtering the branches' TLOC routes so that neither device ever learns the other's TLOC endpoint address.
 
05. After a security policy is deployed to a branch, users can no longer reach an internal application server across the fabric, though they could before the change. Control connections, OMP routes, and all BFD sessions remain healthy, and the route to the application server is present in the branch routing table. Traffic to other destinations is unaffected.
Which cause and direction best explain the failure?
a) A centralized control policy is withdrawing the server's OMP route from the branch's routing table.
b) A Cloud OnRamp path failed to form for the application to reach its optimized cloud destination.
c) A security data policy on traffic egressing the branch toward the application is matching and dropping those flows.
d) The branch WAN Edge lost its organization-name trust with the controllers and dropped all of its control connections.
 
06. You are diagnosing two independent SD-WAN symptoms at the same branch. Symptom A: a cloud prefix is completely absent from the branch routing table even though all tunnels are healthy. Symptom B: an application reaches its destination but rides a transport that violates its intended SLA even though the correct tunnel is up.
Which pairing of symptom to the responsible policy type and direction is correct?
(Choose two.)
a) Symptom B is an application-aware routing policy whose SLA/preferred-path steers the app onto the wrong transport.
b) Symptom A is a centralized control policy filtering the prefix out of the OMP updates sent toward the branch.
c) Symptom A is caused by a security data policy dropping the prefix's traffic in the outbound direction as it leaves the branch.
d) Symptom B is caused by a control policy withdrawing the application's TLOC so no usable tunnel remains.
 
07. A WAN Edge behind a NAT device forms control connections successfully, but its data-plane tunnels to remote TLOCs will not establish and their BFD sessions never come up. The remote sites are reachable over the underlay. The engineer suspects the NAT device is mishandling the tunnel traffic.
Which explanation most directly accounts for control connections succeeding while the data-plane tunnels fail?
a) The NAT device handles the controller session but blocks the UDP flows the tunnels and BFD use, so the tunnel cannot cross it.
b) A centralized control policy blocked the TLOC advertisements, so peers have no tunnel endpoint to target.
c) The device certificate is only valid for control-plane use and is therefore unable to authenticate the data-plane tunnels built to the remote TLOCs.
d) The organization name changed after the tunnels were built, invalidating the branch's trust with the controllers.
 
08. A requirement states: north/south traffic from every branch to internet-based SaaS must first pass through a centralized cloud security stack, and this must be programmed once and applied consistently across all sites. A junior engineer proposes configuring an outbound ACL redirect on each branch WAN Edge instead.
Why is a centralized data policy the better choice than the proposed localized approach?
a) A localized ACL cannot match on destination addresses, so it can never identify SaaS traffic
b) Localized QoS is the correct tool because it can redirect flows to a security stack
c) A centralized data policy programs the service-insertion redirect once on vSmart and applies it consistently to matching north/south flows
d) A centralized control policy would first be required to build the SaaS routes into the fabric, which makes the additional data policy completely redundant
 
09. On a cloud VPN gateway the IPsec SA is up. Counters show the encapsulation (outbound protected) count steadily increasing, while the decapsulation (inbound protected) count stays at zero. The crypto policy matches on both peers and the IKE SA is stable.
What does this pattern most strongly indicate?
a) The pre-shared key is mismatched between the peers, so inbound packets cannot be decrypted and are silently dropped.
b) The remote side never routes the return traffic into its tunnel — a routing or selector problem, not a crypto failure.
c) Phase 1 has failed and the IKE SA must be fully renegotiated before any protected traffic can flow in either direction.
d) A crypto proposal mismatch is present and is silently discarding every inbound protected packet before it can be counted.
 
10. An engineer is planning where each type of Cisco SD-WAN policy is applied within the overlay fabric.
On which device are centralized policies (both control and data) configured and enforced?
a) The vSmart controllers, which apply centralized policy to the fabric
b) The vManage NMS, which enforces the policy in the data plane
c) Each individual WAN Edge router, configured directly through its local CLI
d) The vBond orchestrator, during device authentication and onboarding
