NEW QUESTION # 118
Refer to the exhibit. An engineer is designing the network for a multihomed customer running in AS 111 does not have any other ASs connected to it.
Which technology is more comprehensive to use in the design to make sure that the AS is not being used as a transit AS?
- A. Configure the AS-set attribute to allow only routes from AS 111 to be propagated to the neighbor ASs.
- B. include an AS path access list to send routes to the neighboring ASs that only have AS 111 in the AS path field.
- C. Include a prefix list to only receive routes from neighboring ASs.
- D. Use the local preference attribute to configure your AS as a "non-transit'' AS.
Answer: B
Explanation:
Using an AS path access list helps ensure that only routes originating from the customer AS (AS
111) are advertised to another ASs. By filtering routes with an empty AS path field, AS 111 can prevent being used as a transit AS by disallowing routes coming from another ASs. This is a more comprehensive approach compared to other methods in the options provided.

Which design consideration is valid when you contrast FabricPath and TRILL?
- A. FabricPath permits active-active mode, but TRILL supports only active-standby mode
- B. FabricPath permits ECMP, but TRILL does not
- C. FabricPath uses IS-IS, but TRILL uses VXLAN
- D. FabricPath permits active-active FHRP and TRILL supports anycast gateway
Answer: D
Explanation:
Both FabricPath and TRILL are Layer 2 multipath technologies designed to eliminate spanning tree and allow for efficient forwarding across Layer 2 fabrics using routing techniques:
* B (FabricPath permits active-active FHRP and TRILL supports anycast gateway):FabricPath (Cisco proprietary) integrates with vPC+ to allow active-active First Hop Redundancy Protocol (FHRP) operation at the access layer. This enables multiple default gateways to operate simultaneously, improving resiliency and utilization.TRILL (IEEE standard) uses anycast gateway functionality natively, where multiple switches share the same IP and MAC address for default gateway, allowing hosts to forward to any available gateway, providing active-active behavior at Layer 3.
Other options explained:
* A: Incorrect - both FabricPath and TRILL are based on IS-IS for control plane operations; VXLAN is not part of TRILL.
* C: Incorrect - both FabricPath and TRILL support ECMP (Equal Cost Multi-Path) to utilize multiple paths efficiently.
* D: Incorrect - both technologies allow active-active forwarding at Layer 2.
This comparison highlights CCDE v3.1 design expertise in data center fabric architectures and control plane technologies.
NEW QUESTION # 131
Company XYZ is designing their network using the three-layer hierarchical model. At which layer must the QoS design classify or mark the traffic?
- A. Access
- B. Collapsed core
- C. Distribution
- D. Core
Answer: A
Explanation:
* A (Access):QoS classification and marking should occur as close to the traffic source as possible-at the access layer-so that policies can be consistently applied throughout the network.
Other options explained:
* B/D: QoS policies at these layers rely on markings applied earlier.
* C: Collapsed core is simply core and distribution merged, but marking should still happen at access.
NEW QUESTION # 132
A customer is migrating from a traditional Layer 2 data center to a VXLAN spine-leaf SDN architecture.
Applications cannot be readdressed, and migration must occur incrementally. How should the legacy and new networks be connected?
- A. via a Layer 2 trunk and Layer 3 routed links to border leaf switches
- B. via Layer 3 links to border leaf switches
- C. via a Layer 2 trunk and Layer 3 routed links to spine switches
- D. via a Layer 2 trunk to border leaf switches
Answer: D
Explanation:
#Explanation:
* D: A Layer 2 trunk to the border leaf allows seamless VLAN extension between the legacy Layer 2 domain and the VXLAN-based fabric. This supports application migration without readdressing.
Border leaf switches are used to bridge the traditional and VXLAN segments while maintaining MAC learning and VLAN consistency.
Incorrect Options:
* A & B: Layer 3 links alone would require readdressing or routing, violating the constraint.
* C: Spine switches typically do not handle VLAN bridging or policy enforcement directly.
NEW QUESTION # 133
Which two protocols are used by SDN controllers to communicate with switches and routers? (Choose two.)
- A. NetFlow

- E. NetFlash
Answer: B,D
Explanation:
* B (OpenFlow):OpenFlow is a widely used SDN southbound protocol that enables controllers to directly manage forwarding tables of switches.
* D (Open vSwitch Database - OVSDB):OVSDB is used by SDN controllers (especially in virtualized environments) to manage configuration state and flow entries on Open vSwitch instances.
Other options explained:
* A/C: Non-existent protocols.
* E: NetFlow is a traffic monitoring protocol, not a control interface for SDN controllers.

- A. unneeded tunneling
- B. serialization delay
- C. bandwidth utilization
- D. fate sharing
Answer: D
Explanation:
In virtualized environments, multiple virtual links share the same physical link. If that physical link fails, all virtual links mapped to it fail as well. This drawback is known as fate sharing.
NEW QUESTION # 137
Company XYZ allows employees to use any open desk and plug their laptops in. They want authentication using domain credentials and future capability for segmentation within the same subnet. Which protocol can be recommended?
- A. TACACS+
- B. RADIUS
- C. LDAP
- D. EAP
Answer: D
Explanation:
* B (EAP - Extensible Authentication Protocol):EAP is commonly used for 802.1X port-based authentication, allowing identity-based control for users on the network. This enables policy enforcement, identity-based segmentation (micro/macro segmentation), and leverages existing domain credentials via backend integration.
Other options explained:
* A: LDAP is backend directory, not an authentication protocol for access ports.
* C: TACACS+ is used primarily for administrative access.
* D: RADIUS transports the EAP exchange but is not the authentication protocol itself.
NEW QUESTION # 138
