Free 300-440: Designing and Implementing Cloud Connectivity (ENCC) Exam Questions and Answers
Designing and Implementing Cloud Connectivity (ENCC) is exam 300-440, part of Cisco certifications. In Cisco's current scheme the first digit gives the level: 100 is entry, 200 associate, 300 the CCNP concentration exams, 350 the CCNP core exams that also qualify you for CCIE, 500 specialist and 700 the unproctored sales exams. Older codes such as 400-, 640- and 642- predate the February 2020 restructure, when every CCNA track was collapsed into one exam and CCNP moved to a core-plus-concentration model.

Question #1
An engineer must ensure that voice traffic from Cisco SD-WAN branch sites to workloads in an AWS VPC uses only transport paths with loss of 1% or less, latency of 150 ms or less, and jitter of 30 ms or less. If no path meets these values, traffic must use any available path. Which policy configuration meets these requirements?
Correct answer: B
Explanation
Application-aware routing policy uses BFD-measured loss, latency, and jitter against an SLA class and picks a compliant path, falling back when none qualifies. TLOC preference and next-hop actions do not evaluate path quality. QoS marking affects queuing, not path selection.

Question #2
Drag and drop the connectivity models from the left onto the requirements on the right. Each model is used once. Models: - Native IPsec VPN over the internet - Private connection through a colocation provider - Private connection through an MPLS provider Requirements: Requirement 1: A healthcare company must keep regulated patient data off the public internet and needs a dedicated 10 Gbps path to its Azure environment from a colocation facility where it already has equipment. Requirement 2: A retailer must have encrypted connectivity to its AWS VPC within days to bring a payment workload into an audit scope, and it accepts internet transport. Requirement 3: A company with all branches on an existing MPLS VPN must reach Google Cloud privately and has no presence in any colocation facility.
Drag or tap each item onto its target, then reveal.
- Requirement 1Drop here
- Requirement 2Drop here
- Requirement 3Drop here
Correct answer: Requirement 1 = Private connection through a colocation provider; Requirement 2 = Native IPsec VPN over the internet; Requirement 3 = Private connection through an MPLS provider
Explanation
A dedicated path from an existing colocation presence fits the private, high-bandwidth requirement. Native IPsec is the fastest to deploy and provides encryption over the internet. An MPLS provider can extend the existing VPN to the cloud without a colocation footprint.

Question #3
Which metrics does Cloud OnRamp for SaaS use to calculate the quality score that determines the best path to a SaaS application?
Correct answer: C
Explanation
Cloud OnRamp for SaaS probes each candidate path and derives a quality of experience score from loss and latency. Jitter, BFD timers, and routing attributes are not part of that score.

Question #4
An engineer must verify whether the zone-based firewall is dropping packets on a Cisco IOS XE SD-WAN router. Which command displays the dropped-packet counters?
Correct answer: C
Explanation
show sdwan zbfw drop-statistics lists packets dropped by the zone-based firewall along with the drop reasons. show sdwan security-info displays IPsec and key information, and the other commands show the received policy and path measurements.

Question #5
An engineer must prevent the Cisco SD-WAN sites in site list BRANCH-EU from learning the OMP route for the cloud VPC prefix 10.50.0.0/16. All other routes must remain reachable. Which two configuration steps meet these requirements? (Choose two.)
Select 2 answers.
Correct answer: A, D
Explanation
A centralized control policy filters OMP routes, and its default action must be accept or every other route is rejected. The out direction filters routes the controller advertises to the listed sites, while in filters routes received from them. A localized ACL filters data packets, not route advertisements.

Question #6
A defense contractor must host a workload that processes controlled unclassified information (CUI) in AWS GovCloud (US). The contractor's NIST SP 800-171 controls require that data in transit between the on-premises data center and the VPC is encrypted with FIPS-validated cryptographic modules and does not traverse the public internet. The data center is in a colocation facility that has an AWS Direct Connect location. Which connectivity model meets these requirements?
Correct answer: D
Explanation
The requirements have two parts: a private path and encryption with FIPS-validated modules. Direct Connect supplies the private path, and IPsec between FIPS-validated IOS XE routers supplies the encryption. Direct Connect alone is private but not encrypted by default, and any internet-based option fails the no-public-internet requirement even when strong ciphers are used.

Question #7
Which Cisco SD-WAN policy type modifies the OMP route and TLOC information that the SD-WAN Controller distributes to WAN Edge routers?
Correct answer: A
Explanation
A centralized control policy is enforced on the SD-WAN Controller and filters or changes the OMP routes, TLOCs, and service information it advertises. Data policies and application-aware routing policies act on data traffic at the WAN Edge, and localized control policies apply to routing protocols such as BGP or OSPF on a single device.

Question #8
Refer to the exhibit. An engineer configures an IKEv2 tunnel from an on-premises Cisco IOS XE router to an Azure VPN gateway. The Azure connection uses a custom IPsec/IKE policy with IKE encryption AES256, IKE integrity SHA384, and DH group ECP384. The tunnel does not come up. What is the cause? Exhibit: crypto ikev2 proposal AZ-PROP encryption aes-cbc-256 integrity sha256 group 14 ! Router# debug crypto ikev2 IKEv2:(SESSION ID = 3,SA ID = 1):Sending Packet [To 20.50.10.4:500/From 203.0.113.10:500/VRF i0:f0] IKEv2:(SESSION ID = 3,SA ID = 1):Received Packet [From 20.50.10.4:500/To 203.0.113.10:500/VRF i0:f0] Payload contents: NOTIFY(NO_PROPOSAL_CHOSEN)
Correct answer: D
Explanation
NO_PROPOSAL_CHOSEN is returned during IKE_SA_INIT when none of the proposed algorithms match the peer policy. The router offers SHA-256 and group 14, while Azure requires SHA-384 and ECP384 (group 20). A pre-shared key mismatch would appear later as an authentication failure, and the IPsec transform set is not negotiated until after IKE succeeds.

Question #9
Refer to the exhibit. An engineer configures a centralized application-aware routing policy for Microsoft 365 traffic. The requirement is that this traffic is sent only over tunnels that meet the SLA class, and is dropped when no tunnel meets it. Currently, when both transports exceed the loss threshold, Microsoft 365 traffic still flows over an available tunnel. Which change meets the requirement? Exhibit: policy sla-class O365-SLA loss 2 latency 150 ! app-route-policy BRANCH-APP vpn-list CORP-VPN sequence 10 match app-list O365 ! action sla-class O365-SLA preferred-color biz-internet
Correct answer: B
Explanation
By default, if no tunnel meets the SLA class, traffic is forwarded over any available tunnel. The strict keyword on the sla-class action drops matching traffic when no tunnel meets the SLA. Fallback-best-tunnel does the opposite, selecting the best available tunnel, and removing preferred-color only changes path preference.

Question #10
An engineer must configure the first tunnel interface on an on-premises Cisco IOS XE router for an AWS site-to-site VPN. The AWS configuration file provides these values: • Customer inside tunnel address: 169.254.10.2/30 • AWS inside tunnel address: 169.254.10.1/30 • AWS outside tunnel endpoint: 198.51.100.20 • IPsec profile: AWS-PROFILE The router uses GigabitEthernet1 as its internet-facing interface. Which configuration meets these requirements?
Correct answer: B
Explanation
AWS VPN uses a virtual tunnel interface in IPsec mode, with the customer inside address on the tunnel and the public AWS endpoint as the tunnel destination. GRE mode is not used by AWS-managed VPN. Using the AWS inside address on the tunnel, or using it as the destination, would break addressing or the underlay path.
