問題 #42

答案：

解題說明：

問題 #43
Match the network technology to the customer requirement.

答案：

解題說明：

* Establish redundant links between the aggregation and core layers:When using Layer 3 routing between network layers (like Aggregation and Core),ECMP (Equal Cost Multi-Path)allows the routing protocol (e.g., OSPF, BGP) to utilize multiple links simultaneously if they have the same routing cost. This provides both redundancy (if one link fails, traffic uses the others) and load sharing across the links.
References:AOS-CX IP Routing Guide (OSPF, BGP, ECMP). Relates to "Routing" (16%), "Network Resiliency and virtualization" (8%).
Extend layer 2 across multiple sites:VXLAN (Virtual Extensible LAN)is the overlay technology specifically designed for this purpose. It encapsulates Layer 2 Ethernet frames within UDP packets, allowing them to be tunneled across an underlying Layer 3 network infrastructure, effectively stretching Layer 2 domains (VLANs) between physically separate locations.
References:AOS-CX VXLAN Guide.Relates to "Switching" (19%), "Connectivity" (9%).
Identify individual layer 2 segments in an overlay:Inside the VXLAN header, theVNI (VXLAN Network Identifier)serves as the segment identifier. Each unique Layer 2 segment (like a specific VLAN being extended) is mapped to a unique 24-bit VNI, allowing the overlay network to differentiate between traffic belonging to different L2 domains, even when tunneled between the same VTEPs (VXLAN Tunnel Endpoints).
References:AOS-CX VXLAN Guide, RFC 7348 (VXLAN).Relates to "Switching" (19%), "Connectivity" (9%).
Minimize configuration steps to establish tunnels between sites:While VXLAN provides the data plane encapsulation,EVPN (Ethernet VPN)acts as the modern control plane for VXLAN overlays. Using MP-BGP extensions, EVPN dynamically discovers VTEPs and advertises MAC address and IP reachability information. This significantly reduces configuration complexity compared to older static VXLAN or flood- and-learn methods, as VTEP peer relationships and endpoint learning are automated by the control plane, thus minimizing manual steps to establish connectivity.
References:AOS-CX EVPN Guide.Relates to "Routing" (16%), "Switching" (19%), "Connectivity" (9%).

問題 #44
Refer to the exhibit and cede sample.

What is the effect when you add thestatement "neighbor 10.2.0.3 send-community both" to the ipv4 address family? (Select two.)

A. The feature will be enabled without consequence to the R1established session with R2.
B. It causes R1to negotiate for the ability to import and export all type-1 and lype-2 communities with R2.
C. Itcauses R1to allow the exchange ofcommunities with NLRI records in both inbound and outbound direction
D. It will cause existing BGP peering between R1and R2 to flap.
E. It causes R1 to negotiate the ability to send and receive standard and extended communities with R2.

答案：D,E

解題說明：
The question asks for the effects of adding the command neighbor 10.2.0.3 send-community both to the BGP configuration under the IPv4 address family context for neighbor R2 (10.2.0.3) on router R1.
* send-community both:This command instructs R1 to send both standard (RFC 1997) and extended (RFC 4360) BGP community attributes to neighbor R2. By default, communities are not sent.
* BGP Capability Negotiation:Adding or changing features like community advertisement modifies the BGP capabilities exchanged between neighbors during session establishment. Any change to these capabilities requires the BGP session to be reset (flap) so that the peers can renegotiate using the new capabilities.
* Analysis of Options (Select Two):
* A: Correct (partially). It enables R1 tosendstandard and extended communities. The ability to receivedepends on the peer and local config. The capability isnegotiatedupon session reset.
* B: Incorrect. Changing capabilities requires the session to flap; it's not without consequence.
* C: Incorrect. It primarily enablesoutboundsending from R1. Inbound acceptance is implicit if the neighbor is activated.
* D: Correct. Modifying BGP neighbor capabilities, such as enabling send-community, necessitates a BGP session reset (flap) for the change to take effect.
* E: Incorrect terminology ("import/export", "type-1/type-2 communities").
* Conclusion:The command enables R1 to send communities (A describes the purpose/capability), and adding this command to an existing session will cause the session to flap for renegotiation (D describes the immediate consequence).
References:RFC 1997, RFC 4360, AOS-CX BGP Configuration Guide (communities, neighbor configuration). This relates to the "Routing" (16%) objective.

問題 #45
The customer is experiencing periodic uplink congestion between campus-1's AGG-1 and core. This has boon negativelyaffecting voice communications.The VOIP phones edge mark their packets with DSCP EF. The uplink from AGG-1 to core is LAG1.
The customer has already configured the following class and policy on AGG-1:

Based on this policy, which scrip), when deployed on AGG-1. will improve the reliable forwarding of voice trafficbetween AGG-1 and its uplink to the core?

答案：D

解題說明：
The problem describes uplink congestion affecting VoIP traffic (marked with DSCP EF, value 46) on AGG-
1's LAG1 uplink. The existing configuration classifies this traffic into voip_class and applies voip_policy inbound, setting local-priority 6. To improve reliable forwarding during congestion, VoIP traffic needs strict priority queuing on the egress interface (LAG1).
* Analysis of Options:
* Option A applies a QoS schedule profile globally but doesn't modify the policy's local-priority or apply the schedule profile specifically to the congested LAG.
* Option B modifies voip_policy to set local-priority 7 (mapping DSCP 46 traffic to queue 7) and applies the 8qDwrStrict schedule profile to the egress interface lag 1. In the 8qDwrStrict profile, queue 7 is configured for strict priority, ensuring voice traffic gets precedence over lower-priority traffic during congestion. This aligns with best practices for QoS for VoIP.
* Option C also sets local-priority 7 and applies the schedule profile to lag 1, but the profile itself configures queue 7 with DWRR (Deficit Weighted Round Robin) instead of strict priority, which is less suitable for delay-sensitive voice traffic.
* Option D applies a schedule profile globally and uses DWRR for queue 7.
* Conclusion:Option B is the correct solution because it maps the DSCP EF traffic to the highest local priority (7) and applies a QoS schedule profile to the specific congested uplink (lag 1) that treats queue
7 with strict priority. This ensures voice traffic is prioritized reliably.
References:AOS-CX QoS Guide (specifically sections on Classification, Queuing, Scheduling Profiles, Strict Priority vs. DWRR, applying policies to interfaces/LAGs), DSCP to Queue mapping concepts. This relates to the "Performance Optimization" (6%) and "Connectivity" (9%) objectives.

問題 #46
Which minimal configurations must becompleted for MSTP to work correctly? (Select two.)

A. creating MSTP instances
B. MSTPregion
C. bridge priority number
D. MSTP enabled interfaces
E. revision number

答案：B,E

解題說明：
The question asks for the minimal configurations required for Multiple Spanning Tree Protocol (MSTP) to work correctly on AOS-CX switches.
* Analysis of Options:
* Option A:Correct. The MSTP region name must be configured to define the MSTP region and ensure switches belong to the same region.
* Option B:Incorrect. Bridge priority is optional and defaults to 32768; it's not mandatory for MSTP functionality.
* Option C:Correct. The MSTP revision number is required to ensure consistency across switches in the same region.
* Option D:Incorrect. Enabling MSTP on interfaces is automatic for VLAN-enabled ports; explicit configuration is not mandatory.
* Option E:Incorrect. Creating MSTP instances is optional and only needed for specific VLAN-to- instance mappings.
* Why A and C are Correct:MSTP requires a consistent region configuration across all switches to function correctly. The minimal configuration includes:
* MSTP region name:Defines the region (e.g., spanning-tree config-name REGION1) to group switches.
* Revision number:Ensures region consistency (e.g., spanning-tree config-revision 1).
These settings ensure switches form a single MSTP region, allowing VLAN-to-instance mappings (default instance 0 if not specified) and loop prevention. Other settings, like bridge priority or explicit instance creation, are optional and not strictly required for basic MSTP operation.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Designing and troubleshooting MSTP for redundancy and fault tolerance.
* Switching (19%):Implementing Layer 2 technologies like MSTP for loop prevention.
