NEW QUESTION # 160
Which interface does Cisco Catalyst SD-WAN Cloud OnRamp for IaaS use to set up the customer gateway and map the host VPC to a transit VPC in an AWS environment?
- A. GigabitEthernet4
- B. GigabitEthernet3
- C. GigabitEthernet1
- D. GigabitEthernet2
Answer: D
Explanation:
In Cisco Catalyst SD-WAN Cloud OnRamp for IaaS (specifically in AWS), the GigabitEthernet2 interface is used to:

NEW QUESTION # 161
An application team is getting ready to deploy a new business-critical application to the network. To protect the traffic, the network team must add another queue to the QoS map and then deploy the map to fabric Which configuration slop must be completed prior to adding the queue to the QoS map and applying If
- A. The relationship between the new QoS class and the hardware queue must be configured from the "lisla" page of the Centralized Policy section of vManage. The QoS map is then applied to the WAN interface.
- B. The relationship between die new QoS class and the hardware queue must be configured from the 'lists' page of the Local Policy section of vManage. The QoS map is then applied to the WAN interface
- C. The relationship between the new QoS class and the hardware queue must be configured from the "lists" page of the Centralized Policy section of vManage. The QoS map is then applied to the service-side interface.
- D. The relationship between The new QoS class and the hardware queue must be configured from the 'lists' page of the Local Policy section of vManage. The QoS map is then applied to the service-side interface.
Answer: B
Explanation:
Adding a new QoS queue to handle business-critical application traffic involves several specific steps in Cisco SD-WAN's vManage:
Configure QoS Class and Hardware Queue Relationship:
Navigate to the 'lists' page within the Local Policy section of vManage.
Define the relationship between the new QoS class and the appropriate hardware queue. This step is crucial as it ensures that the new traffic class is mapped correctly to the underlying hardware resources, which are responsible for enforcing the QoS policies.
Applying the QoS Map:
Once the new QoS class and hardware queue relationship is configured, the updated QoS map must be applied to the relevant interfaces.
Specifically, the QoS map should be applied to the WAN interface. This ensures that the new QoS policies are enforced on the traffic as it traverses the WAN, which is typically where QoS management is most critical due to bandwidth constraints and variable network conditions.

NEW QUESTION # 163
Which protocol is configured on tunnels by default to detect loss, latency, jitter, and path failures in Cisco SD-WAN?
- A. BFD
- B. OMP
- C. BGP
- D. TLS
Answer: A
Explanation:
An Application-Aware Routing (App-route) policy allows the SD-WAN fabric to monitor the quality of network paths in real-time and do SLA-driven routing across the best available transports. App- route policies rely on BFD to detect performance issues such as packet loss, latency, and jitter on the overlay tunnels
NEW QUESTION # 164
What does forward error correction addresses in Cisco SO-WAN?
- A. applications with occasional invalid data input and poor performance
- B. reduced application performance degradation rotated to service degradation
- C. inefficient traffic forwarding caused oy inbound shapers
- D. traffic flows with increased delay over a particular transport
Answer: B
Explanation:
Forward Error Correction (FEC) is a technique used in networking to enhance data reliability and performance, particularly over unreliable or lossy networks.
* Forward Error Correction (FEC): In Cisco SD-WAN, FEC helps in mitigating the effects of packet loss and service degradation by encoding redundant data, which can be used to reconstruct lost packets.
This ensures that even if some packets are lost during transmission, the data can still be accurately reconstructed at the destination.
* Addressing Performance Degradation: FEC specifically addresses reduced application performance degradation caused by packet loss and network impairments. By providing this error correction capability, FEC helps maintain the performance and reliability of critical applications over potentially unstable network paths.

- A. HTTP loss and latency metrics to the SaaS application
- B. HTTP loss and latency metrics to the gateway site
- C. BFD loss and latency metrics to the SaaS application
- D. BFD loss and latency metrics to the gateway site
- E. ICMP loss and latency metrics to the SaaS application
Answer: A,D
Explanation:
-The gateway vEdge uses HTTP to obtain SaaS application performance information - The client vEdge will use BFD over the IPSec tunnel to the gateway site to obtain client>gateway path performance information

NEW QUESTION # 171
After receiving an alert regarding a rogue AP, a network engineer logs into Cisco Prime and looks at the floor map where the AP that detected the rogue is located. The map is synchronized with a mobility services engine that determines the rogue device is actually inside the campus. The engineer determines the rogue to be a security threat and decides to stop it from broadcasting inside the enterprise wireless network. What is the fastest way to disable the rogue?
- A. Classify the rogue as malicious in Cisco Prime.
- B. Create an SSID on the WLAN controller resembling the SSID of the rogue to spoof it and disable clients from connecting to it.
- C. Update the status of the rogue in Cisco Prime to contained.

NEW QUESTION # 172
Refer to the exhibit. A WAN Edge device cannot connect to SD-WAN Validator; however, can ping it. Which action resolves the issue?
- A. Switch the peer protocol from DTLS to TLS.
- B. Verify that the SD-WAN Validator IP address is correct.
- C. Install the correct root certificate on WAN Edge.
- D. Modify the system IP on WAN Edge.
Answer: C
Explanation:
The vEdge device shows STATE: connect but LOCAL ERROR: DCONFAIL, which means DTLS connection was attempted but control connection failed - typically due to certificate/authentication issues. Since it can ping the vBond, IP reachability is fine. The most likely cause is a missing or incorrect root certificate, preventing proper TLS handshake and control channel establishment.
