- A. ISR4000 series
- B. ISR9300 series
- C. vEdge-1000 series
- D. ASR9000 series
- E. ASR1000 series
Correct Answer:
AE
Explanation:
The AI agrees with the suggested answer.
The correct answers are A (ISR4000 series) and E (ASR1000 series).
Reasoning:
ISR 4000 series and ASR1000 series routers are well-documented to support Cisco IOS XE SD-WAN images.

Question 3
What is a default protocol for control plane connection?
- A. HTTPS
- B. TLS
- C. IPsec
- D. DTLS
Correct Answer:
D
Explanation:
The AI agrees with the suggested answer of D (DTLS).
DTLS is the default protocol for control plane connections because it provides privacy on control plane tunnels, and it runs over UDP. OMP (Overlay Management Protocol) typically operates within DTLS tunnels.
Other options are incorrect because:
- HTTPS: While HTTPS provides secure communication, it is primarily used for web traffic (over TCP) and not typically the default for control plane connections in networking scenarios like SD-WAN.
- TLS: TLS, like HTTPS, is generally used over TCP and less common as the default for control plane connections that often benefit from UDP's lower overhead.
- IPsec: IPsec is a suite of protocols for secure IP communications, offering strong security, but it's more complex to set up than DTLS and isn't typically the default for control plane connections in some architectures.

Question 4
DRAG DROP -
Drag and drop the devices from the left onto the correct functions on the right.
Select and Place:
Correct Answer:
See interactive view.
Explanation:
The AI agrees with the suggested answer.
The suggested answer correctly maps network devices to their corresponding functions. Here's a breakdown of the reasoning:
- **Firewall:** Its primary function is to **Control traffic based on security policy**. Firewalls examine network traffic against a set of rules and either allow or deny the traffic based on those rules.
- **IPS (Intrusion Prevention System):** The main purpose of an IPS is to **Detect and prevent malicious traffic**. IPS devices actively analyze network traffic for malicious activity and take automated actions to block or mitigate attacks.
- **Load Balancer:** A load balancer's function is to **Distribute traffic across multiple servers**. It ensures that no single server is overwhelmed by requests, improving application availability and responsiveness.
- **Web Server:** Web servers are designed to **Host and serve web pages**. They respond to requests from web browsers by delivering HTML, CSS, JavaScript, and other web resources.
The other options are incorrect because they misattribute the core functions of these devices. For instance, a firewall is not designed to distribute traffic or host web pages, and a web server does not primarily focus on detecting malicious traffic. Each device has a specialized role in the network.
This mapping aligns with fundamental networking principles and device functionalities.

Question 5
Which component of the Cisco SD-WAN control plane architecture should be located in a public Internet address space and facilitates NAT-traversal?
- A. WAN Edge
- B. vSmart
- C. vBond
- D. vManage
Correct Answer:
C
Explanation:
The suggested answer of C (vBond) is correct.
Reasoning:
The vBond orchestrator is the only SD-WAN component that requires a public IP address. This is because vBond is responsible for the initial authentication and orchestration of vEdge devices. vEdges use the vBond to discover the vSmart controllers and vManage servers in the SD-WAN overlay network. To facilitate this, vBond must be reachable from the public internet to allow new vEdges, especially those behind NAT, to join the SD-WAN fabric. It handles NAT traversal to ensure all components can communicate regardless of their location.
Why other options are incorrect:
- A. WAN Edge: While WAN Edge routers participate in data forwarding and application awareness, they don't inherently require a public IP or facilitate initial NAT traversal in the control plane.
- B. vSmart: vSmart controllers are the brains of the SD-WAN network, making routing decisions based on policies. They do not need to be in the public internet space.
- D. vManage: vManage is the network management system and orchestrator that provides a single pane of glass for configuring, monitoring, and troubleshooting the SD-WAN. It does not require a public IP address for its core functionality.

Question 6
Which Cisco SD-WAN WAN Edge platform supports LTE and Wi-Fi?
- A. ISR 1101
- B. ASR 1001
- C. CSR 1000v
- D. vEdge 2000
Correct Answer:
A
Explanation:
Based on the provided information and the discussion summary, the AI agrees with the suggested answer of A (ISR 1101).
Reasoning: The Cisco ISR 1101 platform supports both LTE and Wi-Fi connectivity. The specific model C1101-4PLTEPWX, as mentioned in the discussion, supports LTE and Wi-Fi.
Reasons for not choosing other options:
- ASR 1001: While ASR 1000 series routers are capable platforms, they are not specifically known for native LTE and Wi-Fi support, especially not as a default feature. Additional modules might be needed, but the question implies built-in support.
- CSR 1000v: CSR 1000v is a virtual router and therefore does not have physical interfaces for LTE or Wi-Fi.
- vEdge 2000: vEdge routers are typically deployed in data centers or large branch offices and are not commonly associated with integrated LTE and Wi-Fi capabilities.
The Cisco ISR 1100 series is designed for smaller branch deployments where integrated LTE and Wi-Fi are valuable features for connectivity and redundancy.
Suggest Answer: A
-

- A. dead timer of BFD session
- B. poll-interval of BFD session
- C. hello timer of BFD session
- D. number of BFD sessions
Correct Answer:
D
Explanation:
The AI recommends answer D. number of BFD sessions.
Reasoning:
Based on the discussion, there is a strong consensus that the correct answer is D, which represents the number of BFD sessions. The exhibit is not provided, the best approach is to align with the consensus.
Why other options are incorrect:
Without the exhibit, it's impossible to definitively rule out A, B, and C. However, based on the consensus, these options are less likely to be correct.
-
Question 8
A network administrator is bringing up one WAN Edge router for branch connectivity. Which types of tunnels form when the WAN edge router connects to the
Cisco SD-WAN fabric?
- A. DTLS or TLS tunnel with vSmart controller and IPsec tunnel with vBond controller
- B. DTLS or TLS tunnel with vBond controller and IPsec tunnel with vManage controller
- C. DTLS or TLS tunnel with vBond controller and IPsec tunnel with other WAN Edge routers
- D. DTLS or TLS tunnel with vSmart controller and IPsec tunnel with other WAN Edge routers
Correct Answer:
D
Explanation:
Based on expert knowledge and the discussion provided, the AI recommends answer D.
Reasoning: When a WAN Edge router connects to the Cisco SD-WAN fabric, it establishes DTLS or TLS tunnels with the vSmart controllers for control plane communication and IPsec tunnels with other WAN Edge routers for data plane communication. The vBond orchestrator is primarily involved in the initial device onboarding and authentication process, and it utilizes DTLS for secure communication.
Why not A: This option incorrectly states that the WAN Edge router forms an IPsec tunnel with the vBond controller.
Why not B: This option incorrectly states that the WAN Edge router forms an IPsec tunnel with the vManage controller. The vManage controller is primarily used for management and monitoring purposes.
Why not C: While WAN Edge routers do form IPsec tunnels with each other, this option incorrectly identifies the tunnel to vBond as TLS, when it should be DTLS. Also, vBond does not form a persistent tunnel; it's primarily for initial orchestration.

Question 9
If Smart Account Sync is not used, which Cisco SD-WAN component is used to upload an authorized serial number file?
- A. WAN Edge
- B. vSmart
- C. vBond
- D. vManage
Correct Answer:
D
Explanation:
The AI agrees with the suggested answer.
The correct answer is D. vManage.
Reasoning: When Smart Account Sync is not used, the authorized serial number file is uploaded to vManage. vManage then distributes this information to the other SD-WAN components.
Citations can be found in the list below.
- A. WAN Edge: WAN Edge devices do not handle the upload of authorized serial number files.
- B. vSmart: vSmart controllers manage routing policies but are not directly involved in uploading serial number files.
- C. vBond: vBond orchestrators handle initial device onboarding but do not manage serial number file uploads.
-
Question 10
Which port is used for vBond under controller certificates if no alternate port is configured?
- A. 12344
- B. 12345
- C. 12347
- D. 12346
Correct Answer:
D
Explanation:
The AI suggests that the correct answer is D, which corresponds to port 12346.
The reason for this recommendation is that the default port used by vBond for controller certificates, when no alternate port is configured, is indeed 12346. This is confirmed by Cisco documentation and community discussions.
The provided reference link, while not directly stating the port number, guides through the controller setup, and other Cisco documentation explicitly mentions the default port.
The other options (12344, 12345, and 12347) are incorrect because they are not the default port used by vBond for controller certificate orchestration.
