質問 # 56
Ever since a recent firewall change at your WAN/lnternet edge, the 8GP state in your VSX pair has not returned to Established. What should you check to restore BGP functionality at the site?

A. Restart the routing service so thatBGP auto-discovers its neighbors.
B. Confirm that BGP Peer AS has not changed.
C. Confirm that appropriate TCP ports are still allowed.
D. Restart NAT service for the BGP interface.

正解：C

解説：
The BGP state on a VSX pair is stuck (not 'Established') after a recent firewall change at the WAN/Internet edge, where the BGP peering likely occurs.
* BGP and Firewalls:BGP establishes sessions usingTCP port 179. Firewalls located between BGP peers must explicitly permit TCP port 179 traffic bidirectionally for the peering to establish and maintain. Firewall changes are a frequent cause of broken BGP sessions.
* Troubleshooting Steps After Firewall Change:The most logical first step is to verify that the firewall change did not inadvertently block TCP port 179 between the configured BGP neighbor IP addresses.
* Analysis of Options:
* A: Restarting routing service is disruptive and not the first step.
* B: Confirming that appropriate TCP ports (specifically 179) are still allowed through the firewall directly addresses the most probable cause related to the firewall change event.
* C: Restarting NAT service is likely irrelevant unless NAT is incorrectly configured for BGP peers.
* D: Confirming the peer AS is a basic configuration check but less likely related to thefirewall changeevent than port blocking.
* Conclusion:Given the problem occurred immediately following a firewall change, verifying that the firewall still permits TCP port 179 between the BGP peers is the most direct and likely troubleshooting step.

質問 # 57
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. Itcauses R1to allow the exchange ofcommunities with NLRI records in both inbound and outbound direction
B. It causes R1to negotiate for the ability to import and export all type-1 and lype-2 communities with R2.
C. It causes R1 to negotiate the ability to send and receive standard and extended communities with R2.
D. It will cause existing BGP peering between R1and R2 to flap.
E. The feature will be enabled without consequence to the R1established session with R2.

正解：C、D

解説：
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).

質問 # 58
A customer is trialing the below colorless port configuration on a single switch and has noticed that users roaming to access points connected to the test switch are unable to receive an IP address on the corporate Wi- R network, which is operating in bridged mode All other SSIDs are working as expected and the AP is Online in HPE Aruba Networking Central.
The security team reports that there have been no failed authentications m HPE Aruba Networking ClearPass Access Tracker and that the last entry for the wiredport is returning the KADIUS Aruba-User-Hold attribute
'Access_Point.
Which configuration change is required to resolve the issue?

A. port access role Access_point auth-mode device-mode
B. interface 1/1/1-1/1/48
aaa authentication port-access client-limited 0
C. interface 1/1/1/1-1/48
port-access onboarding-method concurrent enable
D. port-access client-move enable

正解：B

解説：
The issue involves users roaming to APs connected to a test switch failing to receive an IP address on the corporate Wi-Fi network (bridged mode), with ClearPass reporting a RADIUS Aruba-User-Role attribute of Access_Point. The goal is to identify the configuration change needed to resolve this issue.
* Analysis of Options:
* Option A (port-access client-move enable):Enables client movement between ports but does not address the AP authentication issue.
* Option B (aaa authentication port-access client-limit 0):Correct. Setting the client limit to 0 on the switch ports (1/1/1-1/1/48) disables MAC authentication for APs, allowing them to be treated as trusted devices and preventing the application of an incorrect role.
* Option C (port-access onboarding-method concurrent enable):Enables concurrent onboarding but is unrelated to the AP role issue.
* Option D (port-access role Access_point auth-mode device-mode):Configures a device mode role but does not resolve the IP assignment issue caused by incorrect authentication.
* Why Option B is Correct:The issue arises because the switch is applying 802.1X or MAC authentication to the AP ports, resulting in ClearPass assigning the Access_Point role, which restricts client connectivity. By setting aaa authentication port-access client-limit 0 on the AP-connected ports (1
/1/1-1/1/48), the switch disables port-access authentication for these ports, treating the APs as trusted devices. This allows clients to authenticate properly via the AP and receive IP addresses in bridged mode, resolving the issue.
* Relevance to Certification Objectives:
* WLAN (9%):Involves troubleshooting wireless functions and Layer 2 issues related to AP connectivity.
* Authentication/Authorization (9%):Includes troubleshooting ClearPass integration and 802.1X configurations.
* Security (10%):Covers troubleshooting wired 802.1X implementations.

質問 # 59
A pair of CX 8325 series switches a configured in a VSX cluster. Which function is executed on both VSX members during normal operation?

A. replies to ARP requests with thecluster vMAC
B. routes PIM and PIM-DR
C. relays DHCP requests or serves DHCP offer
D. periodically sends gratuitous ARP and broadcast hello packets

正解：A

解説：
The question asks which function is executed on both VSX members (CX 8325 switches) during normal operation in a VSX cluster.
* Analysis of Options:
* Option A:Correct. Both VSX switches reply to ARP requests with the cluster's virtual MAC (vMAC) for SVIs configured with active-gateway, ensuring consistent Layer 3 forwarding.
* Option B:Incorrect. PIM (Protocol Independent Multicast) and PIM-DR roles are typically handled by one switch, not both, in a VSX cluster.
* Option C:Incorrect. DHCP relay or server functions are not necessarily performed by both switches simultaneously.
* Option D:Incorrect. Gratuitous ARP and broadcast hello packets are typically sent by the primary switch or specific protocols, not both VSX members for all cases.
* Why Option A is Correct:In a VSX cluster, the active-gateway feature allows both switches to respond to ARP requests for Switched Virtual Interfaces (SVIs) using a shared virtual MAC address (vMAC). This ensures seamless Layer 3 forwarding and high availability, as clients receive consistent ARP replies regardless of which VSX switch processes the request. The vsx-sync feature ensures the vMAC is synchronized, enabling both switches to perform this function during normal operation, as per HPE Aruba Networking's VSX architecture.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Designing and troubleshooting VSX for redundancy and active-active forwarding.
* Switching (19%):Implementing Layer 2/3 technologies, including ARP handling in VSX.
* Routing (16%):Ensuring consistent Layer 3 operations in VSX environments.

質問 # 60
Match the BGP connection slates to the conditions thatcould have caused that state.

正解：

解説：

Explanation:
The router is able to process update messages. -->established
The router is waiting for the neighbor's open message. -->open sent
Routers have agreed on matching feature sets. -->open confirm
The session establishment has timed out. -->idle
This question requires matching BGP connection states from the BGP Finite State Machine (FSM) to descriptions of conditions that occur within or lead to those states.
* Idle:This is the initial state where BGP awaits a start event or retries after a failure. It's also the state entered upon error detection or session closure, including timeouts during connection attempts.
* Matches:"The session establishment has timed out." - A timeout during the connection process forces the BGP process back to the Idle state to potentially retry later.
* OpenSent:After a TCP connection is established, the local router sends a BGP OPEN message with its parameters (AS number, capabilities, etc.) and transitions to the OpenSent state while waiting to receive an OPEN message from its BGP neighbor.
* Matches:"The router is waiting for the neighbor's open message."
* OpenConfirm:Once the router receives an OPEN message from its neighbor and validates the parameters (e.g., matching AS, compatible capabilities), it sends a KEEPALIVE message and moves to the OpenConfirm state. It waits for a KEEPALIVE from the neighbor to confirm the session. Basic parameter checks and capability negotiations are successfully completed in this phase.
* Matches:"Routers have agreed on matching feature sets." - This agreement happens upon successful validation of the OPEN messages exchanged.
* Established:This is the final, stable state where BGP peering is successful. Both routers have accepted each other's parameters via the OPEN messages and confirmed the session with KEEPALIVEs. In this state, the routers can exchange UPDATE messages containing routing information.
* Matches:"The router is able to process update messages."
References:RFC 4271 (BGP4 specification - Section 8, Finite State Machine), BGP configuration and troubleshooting guides for AOS-CX. This relates to the "Routing" (16%) and "Troubleshooting" (10%) objectives.
