Question No : 1

Refer to the exhibits.
Exhibit 1



Exhibit 2



Exhibit 1 shows the topology for the network. The network administrator sees the log entries shown in Exhibit 2.
Which type of failure is indicated?

• A.A link between Switch-1 and Switch-2 went down. BFD detected the lost connectivity and behaved as expected.
• B.Graceful restart helper was not enabled on Switch-2, so BFD was unable to operate correctly, and the session was taken down.
• C.A hardware issue caused a unidirectional link; BFD detected the issue at Layer 2 and prevented a broadcast storm.
• D.BFD was set up incorrectly on Switch-2, so it caused Switch-2 to lose adjacency with Switch-1 rather than repair the session.

An AOS-Switch enforces 802.1X. It receives an Access-Accept with this HPE VSA from its Radius server:
Attribute Name and ID = HPE-User-Role (25) Value = contractor
The switch then rejects the client.
What is one requirement for the switch to accept the message and authorize the client?

• A.The initial user role must be set to the factory default permit any role.
• B.User role authorization must be enabled globally on the switch.
• C.An aaa authentication local user group must have the contractor name.
• D.The RADIUS server settings must permit dynamic authorization.

Switch-1 and Switch-2 connect on interface A23. The switches experience a connectivity issue. The network administrator sees that both switches show this interface as up. The administrator sees the output shown in the exhibit on Switch-1.
What is a typical issue that could cause this output?

• A.asymmetric routing introduced by a routing protocol
• B.an issue with VLAN mismatch
• C.mismatched subnet mask on the VLAN for the link
• D.a jumbo frame mismatch

The exhibit shows configurations for interface 5 and VLAN 20. Note that DHCP snooping and ARP protection are also enabled.
A network administrator finds that interface 5 on an AOS-Switch is disabled. The administrator re-enables the interface, but it shuts down again.
What should the administrator investigate?

• A.a device that sends too much unicast traffic
• B.rogue DHCP server
• C.a loop on the interface
• D.a device that sends unauthorized ARP messages

What is one difference between BPDU protection and root guard?

• A.BPDU protection works with RPVST+, RSTP, and MST
• B.Root guard works with RSTP or MSTP, but not RPVST+.
• C.BPDU protection blocks a port if it receives any BPDU, but root guard blocks a port only if the BPDU indicates a better root path.
• D.BPDU protection is typically implemented on edge ports, but root guard is typically implemented on uplinks with the root port role.
• E.BPDU protection drops BPDUs received on a port, but does not block the port. Root guard blocks the port if it receives a BPD

The implementation plan for AOS-Switches calls for them to implement port-based tunneled node. The Aruba Mobility Controllers that will support the AOS-Switches run software 8.1. The controllers will also support APs, are managed by Mobility Master, and use clustering.
Which issue with this plan needs to be addressed?

• A.The controllers cannot support tunneled node with AOS-Switches when they are managed by the Mobility Master.
• B.The switches cannot connect to controllers that also support APs.
• C.The controllers must have their software updated before they can support the switches.
• D.The switches must use role-based tunneled node to work with clustering controllers.

• B.It drops all DHCP traffic and logs a security event.
• C.It accepts both client and server packets as long as they match the DHCP binding table.
• D.It accepts client packets, but drops packets from a DHCP server.

A network administrator needs to create a backplane stack with four AOS-Switches. The administrator wants to choose which switch becomes the commander.
Which procedure meets those needs?

• A.Boot all of the switches at the same time and then connect the backplane stacking links. Then, access the desired commander, and make sure it has member ID 1.
• B.Configure backplane switches settings on each switch while disconnected. Make sure the desired commander has priority value 1. Then, connect the switches.
• C.Boot up the desired commander first and make sure stacking is enabled on it. Then, connect the stacking links and boot the other switches.
• D.Configure backplane switching settings on each switch while disconnected. Make sure the desired commander has member ID 1. Then, connect the switches.

Switch-1 and Switch-2 are configured to provide VRRP in VLAN 2. The default gateway for VLAN 2 is set to the VRRP virtual IP. Client-1 in VLAN 2 cannot ping its default gateway.
Based on the exhibits, what can administrators determine?

• A.The VRRP preempt delay time has not yet expired, and administrators should try to ping the gateway again in several minutes.
• B.Switch-1 and Switch-2 have the same virtual router I
• C.The conflict interferes with connectivity.
• D.Preempt mode is enabled on both Switch-1 and Switch-2, so the Master role continues to alternate between them, and the pings go astray.
• E.This is the expected behavior, and Switch-1 should still be able to route traffic for Client-1.
