With the configuration oftwo CX 8325 switches in the VSX cluster, how would you prepare a link- aggregation for a 7000 gateway for a zero-touch provision to support protocol-based port redundancy?

The goal is to configure a Link Aggregation Group (LAG) on a VSX cluster (pair of CX 8325 switches) that connects to an Aruba 7000 series gateway undergoing Zero Touch Provisioning (ZTP). The LAG needs to support “protocol-based port redundancy” (LACP) and allow connectivity during ZTP.
* VSX Requirement:Since the LAG connects to two separate physical switches operating as a VSX pair, the LAG must be configured as a Multi-Chassis LAG (MC-LAG) on the switches. This allows the gateway to form a single LAG across both upstream devices. The command multi-chassis under the interface lag <id> context enables this.
* Protocol Redundancy Requirement:”Protocol-based port redundancy” indicates that Link Aggregation Control Protocol (LACP) should be used to dynamically negotiate and manage the LAG bundle between the switches and the gateway. The command lacp mode active enables LACP in active negotiation mode.
* ZTP Requirement:During ZTP, the gateway might not have its full configuration, including LACP settings, enabled immediately. To ensure the gateway can establish basic IP connectivity for ZTP (e.g., reach Activate/Central via DHCP/DNS), the switch ports should allow traffic even if LACP negotiation hasn’t completed. The lacp fallback feature enables this, allowing individual LAG member ports to become active if LACP PDUs are not received from the peer.
* Analyzing the Options:
* A)Configures lacp mode active and lacp fallback butlacksthe multi-chassis command required for VSX.
* B)Correctly configures the LAG as multi-chassis, enables lacp mode active, and enables lacp fallback. This meets all requirements.
* C)Configures multi-chassis but uses potentially older or less standard syntax lacp enable and lacp fail-over instead of lacp mode active and lacp fallback.
* D)Lacks the multi-chassis command and uses potentially older/less standard syntax.
* Conclusion:Option B provides the complete and correct configuration using standard AOS-CX syntax to create an MC-LAG on the VSX pair with LACP enabled for redundancy and LACP fallback enabled to support gateway connectivity during ZTP.

質問 32
You want to use OSPF to advertise a only .16 summary route for the SVlsbelow to a neighbor In the same area (area 0).
Which configuration will achieve this?

The goal is to configure OSPF on a router so that it advertisesonlya 10.1.0.0/16 summary route for the specific SVIs (VLAN 11, 12, 13, assumed to be within the 10.1.x.x range) to its OSPF neighborswithin the same area (Area 0).
* OSPF Intra-Area Behavior:A fundamental principle of OSPF (link-state protocols) is that all routers within the same area must have an identical Link State Database (LSDB) for that area. This means all routers learn about all the specific networks (Type-1 Router LSAs, Type-2 Network LSAs) within their area. OSPFv2 doesnotsupport summarizing routes in a way that hides specific network LSAs from other routerswithin the same area. Summarization occurs only at area boundaries (by ABRs using Type-
3 Summary LSAs via the area range command) or for external routes redistributed into OSPF (by ASBRs using Type-5 External LSAs via the summary-address command).
* Analysis of Options:
* A) area 0 range 10.1.0.0/16:This command is used on an Area Border Router (ABR) to summarize routes originatingfromArea 0 when advertising theminto another area(e.g., the backbone). It does not affect LSA floodingwithinArea 0. It also includes redistribute connected, which is unrelated here.
* B) summary-address 10.1.0.0/16:This command is used on an Autonomous System Boundary Router (ASBR) to summarizeexternalroutes being redistributed into OSPF. It is not used for summarizing internal OSPF routes like SVIs defined within an OSPF area.
* C) & D) summary-address 10.1.0.0/16:Same issue as B; incorrect command for summarizing internal OSPF routes.
* E) area 0 range 10.1.0.0/16:Similar to A, this uses the area range command. It correctly shows the SVIs configured for OSPF Area 0 first. However, like A, this command performs inter-area summarization on an ABR and does not suppress the specific LSAswithinArea 0.
* Conclusion:The question asks for something that OSPFv2 cannot do: advertiseonlya summary route within the same area while suppressing specifics. Therefore, none of the configurations will achieve the exactstated outcome. However, if the question is flawed and intends to ask which configuration uses the correct command structure for summarizinginternalOSPF routes (even if only effective between areas), then the area range command is the relevant one. Both A and E use this command. Option E is slightly better structured as it shows the interfaces being added to OSPF Area 0 first. Assuming this is the intended direction despite the impossibility of the specific request, E is the most plausible choice among the given options.

You are troubleshooting a network issue on a VSX cluster. The network was functioning properly yesterday but today the network operations center is receiving alerts. On one of the two VSX members, a ‘show interface brief’ indicated that all VSX LAGs are “down by feature”.
What could be the cause of this condition?

LAGs were disabled because a split-brain condition was detected.

Both VSX members are configurated as Primary.

VSX has detected a firmware version mismatch.

VSX-sync is not enabled on the cluster.

質問 35
Refer to the four numborod slops in the exhibit.

Which action is the fourthstep in applying a role-to-role ACL on thetraffic from mobile device M1 to roleH2?

Switch A1 determines the destination role based on destination MAC or destination IP and enforces role-to-role ACLs.

Gateway 1 forwards thetraffic over the sialic VXLAN tunnel to the edge switch; this packet carries the Group Policy ID corresponding to the role ofM1.

The AP forwards the packet from M1 to gateway 1.

The edge switch acts as the intermediate node and transfers the Group Policy ID over static VXLAN to dynamic VXLAN tunnel and forwards the packet to switch Al.

The question asks for the fourth step in applying a role-to-role ACL on traffic from a mobile device (M1) to a role (H2) in a network using Dynamic Segmentation with VXLAN. This follows question 17, which identified the first step as the AP forwarding the packet to the gateway.
* Analysis of Options:
* Option A:Correct. The fourth step involves the destination switch (Switch A1) determining the destination role (H2) based on the destination MAC or IP address and applying the role-to-role ACL to permit or deny the traffic.
* Option B:Describes an earlier step (likely second or third) where the gateway forwards traffic over a VXLAN tunnel.
* Option C:Describes the first step, as identified in question 17.
* Option D:Describes an intermediate step (likely third) where the edge switch transfers the Group Policy ID over VXLAN.
* Why Option A is Correct:In HPE Aruba Networking’s Dynamic Segmentation architecture, the traffic flow for role-based ACLs in a VXLAN environment follows these steps:
* The AP forwards the packet from M1 to the gateway (question 17).
* The gateway assigns the source role (M1’s role) and forwards the packet over a VXLAN tunnel with the Group Policy ID.
* The edge switch transfers the Group Policy ID to the destination switch (A1) via VXLAN.
* Switch A1 determines the destination role (H2) based on the destination MAC or IP address and enforces the role-to-role ACL, as defined in the Group-Based Policy (GBP).
The fourth step is critical for policy enforcement, ensuring that traffic complies with the security policies defined between the source and destination roles, providing secure network segmentation.
* Relevance to Certification Objectives:
* Security (10%):Designing and troubleshooting role-based security policies in customer networks.
* Switching (19%):Implementing Layer 2/3 interconnection technologies like VXLAN for policy enforcement.
* WLAN (9%):Troubleshooting wireless traffic flows in Dynamic Segmentation.

質問 45
A customer hassot a requirement for VLAN 151 to be an isolated VLAN. A colleague has copied and pasted a partialconfiguration, but you do not achieve the desired outcome. This is the code that was added:
What should be added to the configuration before this code to achieve the desired result?

The customer requires VLAN 151 to be configured as an isolated Private VLAN. A partial configuration was added, but the desired outcome wasn’t achieved. We need to determine which configuration snippet should be addedbeforethe (unspecified) partial configuration to correctly set up the Private VLAN structure.
* Private VLAN Configuration Fundamentals:
* APrimary VLANmust be defined. This VLAN carries traffic between promiscuous ports and ports in associated secondary VLANs.
* Secondary VLANs(either isolated or community) are associated with the primary VLAN.
* Ports are then mapped to either the primary VLAN (promiscuous ports, typically router/firewall connections) or a secondary VLAN (host ports). Isolated ports within thesameisolated VLAN cannot communicate with each other.
* Analyzing the Options (Assuming VLAN 15 is the intended Primary):
* A)
vlan 15
private-vlan primary
vsx-sync
This correctly defines VLAN 15 as the Primary Private VLAN. The vsx-sync command ensures this configuration is synchronized across a VSX pair (relevant if applicable). This is the necessary prerequisite before defining VLAN 151 as an isolated secondary VLAN and associating it with VLAN 15.
* B)isolated-vlan primary is incorrect syntax. The command is private-vlan primary.
* C)primary-vlan isolated 151 is incorrect syntax for defining either the primary or secondary VLAN type/association within the primary VLAN context.
* D)private-vlan isolated 151 within the vlan 15 context is incorrect syntax. The private-vlan isolated command belongs under the configuration of the secondary VLAN (VLAN 151 in this case).
* Conclusion:Before configuring VLAN 151 as private-vlan isolated and associating it, the primary VLAN must be defined. Option A correctly shows the command (private-vlan primary) under the intended primary VLAN’s configuration (vlan 15) to establish it as the primary VLAN.
