NEW QUESTION # 96

Refer to the exhibit. An engineer must design a solution that allows a user to choose which private Cisco Catalyst SD-WAN network they want to connect to AWS. The solution must automatically identify the AWS VPC and other cloud services based on the user credentials. What must be used?

• A. Segment routing
• B. AWS Direct Connect
• C. Transit VPC for AWS
• D. IPsec VPN

Answer: C

Explanation:
In Cisco Catalyst SD-WAN cloud integration, when the requirement is:
* Automatically discovering AWSVPCs
* Automatically identifying AWSservices
* Allowing the user to choose whichprivate SD-WAN networkconnects to the cloud
* UsingAWS credentials(Access Key / Secret Key) for automatic provisioning
...the Cisco-supported mechanism is theCisco SD-WAN Transit VPC solution.
Why Transit VPC is the correct answer:
* It is specifically designed to integrateCisco SD-WANwith AWS environments.
* Uses AWS APIs and user credentials to automatically discover:
* VPC IDs
* Subnets
* Regions
* Routing tables
* Automatically deploys and configures CSR1000v or Catalyst 8000V routers into the VPC.
* Provides a centralized "hub" in AWS to interconnect multiple SD-WAN sites.
* Enables the user to choose which SD-WAN segments connect to which VPCs.
This matches the requirement ofautomatic cloud resource identification based on user credentials.
Why the other options are incorrect
A). AWS Direct Connect
* This is a physical/private Layer 2 cloud connection.
* It doesnotauto-discover VPCs or integrate through credentials.
* It does not provide automated SD-WAN service provisioning.
C). IPsec VPN
* Works for connectivity but ismanual, not automated.
* Does not identify AWS cloud resources via credentials.
D). Segment routing
* A transport technology used inside SP networks, irrelevant to AWS API-based VPC discovery.
Thus, onlyTransit VPCprovides automatic AWS cloud discovery and integration with SD-WAN.

NEW QUESTION # 97

Refer to the exhibit. An engineer must configure dual-homing with single active redundancy in a BGP EVPN VXLAN fabric. Which command must be run on the leaf router to complete the EVPN Ethernet segment configuration?

• A. vlan configuration 101
• B. redundancy single-active
• C. replication-type static
• D. default-gateway advertise

Answer: B

Explanation:
In a BGP EVPN VXLAN multi-homing design, Ethernet Segment Identifiers (ESIs) are used to represent a set of links from one or more leaf switches to the same downstream device (such as a CE, firewall, or aggregation switch). By default, when multiple leafs share the same ESI, the EVPN design supportsall-active redundancy, where all participating leafs can forward traffic for that Ethernet segment simultaneously.
However, some use cases-like connecting to devices that do not support multipath forwarding or for strict active/standby redundancy-requiresingle-activemulti-homing. In single-active mode, only one leaf in the Ethernet segment forwards traffic at any time; the other leaf(s) act as standby and only take over if the active node fails. This behavior is explicitly controlled in the EVPN Ethernet-segment configuration.
On Cisco platforms for EVPN VXLAN fabrics, this is configured under thel2vpn evpn ethernet-segment stanza using the command:
l2vpn evpn ethernet-segment 1
identifier type 0 01.01.01.10.10.10.10.10.10.10
redundancy single-active
* identifier type 0 ... defines the ESI for the multi-homed connection.
* redundancy single-active specifies that only one leaf in that ESI is allowed to be active at a time, thus enablingdual-homing with single-active redundancy.
The other options do not relate to Ethernet-segment redundancy mode:
* B. default-gateway advertiseis used in EVPN anycast gateway configurations to advertise the default gateway MAC/IP, not for ESI redundancy.
* C. replication-type staticis associated with multicast or ingress replication behavior for VXLAN VTEPs, not Ethernet-segment redundancy.
* D. vlan configuration 101is a VLAN configuration context command and has no effect on EVPN ESI redundancy.

NEW QUESTION # 98
An engineer must enable the highest level of logging when troubleshooting Cisco NFVIS. Which command must be run?

• A. system set-log logtype configuration level error
• B. system set-log logtype operational level debug
• C. system set-log logtype configuration level warning
• D. system set-log logtype configuration level critical

Answer: B

Explanation:
Comprehensive and Detailed Explanation
Cisco NFVIS logging levels (from lowest to highest):
* critical
* error
* warning
* info
* debug#highest verbosity
To capture maximum diagnostic detail, engineers must enabledebuglogging on theoperational log type, which records system activity and runtime behavior.
Thus the correct command is:
system set-log logtype operational level debug
This provides the deepest troubleshooting visibility.

NEW QUESTION # 99
Logging with syslog supports network assurance by:

• A. Enabling detailed event logging and analysis
• B. Facilitating real-time performance adjustments
• C. Enhancing physical network speeds
• D. Reducing the need for automatic fault management

Answer: A

NEW QUESTION # 100
An engineer must design a solution to provide safe channels between peer-to-peer devices, ensure that unauthorized users cannot break into the network, and ensure that listening devices on the Internet cannot intercept communication transmitted over the network. What must be used?

• A. Segment routing
• B. AWS Direct Connect
• C. Transit VPC for AWS
• D. IPsec VPN

Answer: D

Explanation:
Comprehensive and Detailed Explanation (Cisco SP Cloud Knowledge)
The requirement describes:
* Secure communication between sites or devices
* Protection from eavesdropping over the Internet
* Cryptographic tunnels
* End-to-end authentication and encryption
This exactly matches the purpose of anIPsec VPN, which provides:
* Encrypted secure tunnels
* Authentication and integrity protection
* Confidentiality even across untrusted networks such as the Internet
Other options do not provide encrypted peer-to-peer channels:
* AWS Direct Connect# private link to AWS, not peer-to-peer encryption
* Segment Routing# traffic engineering, not security
* Transit VPC# routing architecture, not encryption
Thus the correct answer isIPsec VPN.

NEW QUESTION # 101
Which of the following protocols is NOT directly related to implementing ECMP?

• A. SMTP
• B. OSPF
• C. IS-IS
• D. BGP

Answer: A

NEW QUESTION # 102


Refer to the exhibit. An engineer is troubleshooting an issue where Cisco switch Switch_A fails to establish OTV connectivity to Cisco switch Switch_C. What is the cause of the issue?

• A. The broadcast group must be 232.1.1.0.
• B. The join interface must be e1/1.
• C. The control group must be 232.1.1.0.
• D. The join interface must be g1/0.

Answer: D

Explanation:
In Cisco Overlay Transport Virtualization (OTV), thejoin interfaceis the Layer 3 interface that connects the edge device to thetransport network(the routed core / WAN) where multicast groups (control, data, broadcast) are reachable.
From the topology:
* Interfaceg1/0on Switch_A is connected to the routed 20.20.20.0/30 link toward Switch_C (the transport
/ WAN).
* Interfaceg1/1is a trunk toward Switch_B and carries extended VLANs (101, 111), so it belongs to the internal site-facing side, not the transport.
In the show otv output, the join interface is incorrectly configured asg1/1 (20.20.20.2), which is an internal trunk and not the correct routed interface to the OTV transport network. Because the join interface does not face the multicast-enabled transport, OTV cannot establish adjacency and the VPN state remains DOWN.
Correct configuration should use:
otv join-interface GigabitEthernet1/0
Options A and C about group addresses are not the issue; addresses shown (224.x for control/broadcast and
232.x for data group range) are valid multicast ranges. Option D (e1/1) is also an internal access/trunk interface and not the WAN transport interface.

NEW QUESTION # 103
A large company's legacy network is set up with equipment from multiple vendors. The company engaged a network architect to optimize the network for virtualization. The architect must ensure robust and efficient operation, considering the company's immediate needs but also anticipating future network complexities and scalability requirements. The chosen strategy must be capable of integrating seamlessly with existing systems, while providing a pathway for innovation and growth. The solution must facilitate end-to-end service automation throughout the entire lifecycle, and the implementation must ensure the validation, execution, and abstraction of network configurations and services. Which action must be taken to meet the requirements?

• A. Implement a flexible service-modeling approach that leverages automation for ongoing management and refinement as demands on the network evolve.
• B. Implement a service life-cycle approach with simplified monitoring that plans for post-deployment adjustments to be incorporated into the automation CI/CD pipeline.
• C. Implement a configuration-management approach that allows for configuring each network device individually to optimize its performance.
• D. Implement a service-modeling approach with a static YANG one-size-fits-all model that includes the unique requirements of each different network element.

Answer: A

Explanation:
Cisco NSO-based orchestration principles in a multi-vendor environment require:
Service modeling using flexible, reusable YANG models
Abstraction of vendor-specific device differences
Transaction-safe configuration validation and execution
End-to-end automation across lifecycle stages (Day-0, Day-1, Day-N)
Scalability and adaptability for evolving requirements
Option C aligns perfectly with NSO service-modeling approaches:
Service models must be flexible, not rigid, enabling changes as technologies and needs evolve.
The architecture must support continuous refinement, enabling multi-vendor abstraction and lifecycle automation.
This ensures the network evolves seamlessly while remaining stable and automated.
Why the Other Options Are Incorrect
A - Simplified monitoring and post-deployment adjustments do not meet the core need for full lifecycle service modeling and abstraction.
B - Configuring devices individually contradicts the entire purpose of orchestration and abstraction.
D - A static YANG model cannot accommodate multi-vendor environments or future scalability.
Thus, only Option C matches full NSO-capable service modeling requirements.
