Question15: Examine the network topology.

Company XYZ has two connections to a service provider (ISP1). Here is the configuration of Router1:

Here is the configuration of Router2:

Based on configuration of Router1 and Router2, which BGP metric is being manipulated?

Question16: Examine the AOS-CS switch output:

Based on this output, what is correct?

Question17: How should a network administrator add NAE scripts and implement NAE agents that will run on an AOS-CX switch?

Question18: Examine the output from an AOS-CX switch implementing a dynamic segmentation solution involving downloadable user roles:
Switch# show port-access role clearpass
Role information:
Name : icxarubadur_employee-3044-2
Type : clearpass
Status: failed, parsing_failed
Reauthentication Period :
Authentication Mode :
Session Timeout :
The downloadable user roles are not being downloaded to the AOS-CX switch. Based on the above output, what is the problem?

Question19: An administrator wants to leverage always-on PoE on AOS-CX switches. Which statement is correct regarding this feature?

Question20: A company requires access by all users, guests, and employees to be authenticated. Employees will be authenticated using 802.1X, whereas guests will be authenticated using captive portal. Which type of authentication must be configured on an AOS-CX switch ports where both guests and employees connect?

Question21: What would prevent two OSPF routers from forming an adjacency? (Select two.)

Question22: What is a concept associated with PIM sparse mode (SM)?

Question23: An administrator is implementing a multicast solution in a multi-VLAN network. Which statement is true about the configuration of the switches in the network?

Question24: What are best practices when implementing VSX on AOS-CX switches? (Choose two.)

Question25: Which statement is correct regarding ACLs and TCAM usage?

Question26: A company has a third-party AAA server solution. The campus access layer was just upgraded to AOS-CX switches that perform access control with MAC-Auth and 802.1X. The company has an Aruba Mobility Controller (MC) solution for wireless, and they want to leverage the firewall policies on the controllers for the wired traffic.
What is correct about how the company should implement a security solution where the wired traffic is processed by the MCs?D18912E1457D5D1DDCBD40AB3BF70D5D

Question27: Examine the partial output of the BGP routing table of an AOS-CX switch:

The switch is learning about four possible path to reach the 1.0.0.0/8 network. Based on this output, which next-hop route will the AOS-CX select to be placed in the IP routing table?

Question28: An administrator is managing a VSX pair of AOS-CX switches An administrator configures the following on the primary AOS-CX switch:

Question29: An administrator has configured the following on an AOS-CX switch:

What is the correct ACL rule configuration that would allow traffic from anywhere to reach the web ports on the two specified servers?

Question30: Which AOS-CX switches support weighted fair queuing (WFQ)?

Question31: What must a network administrator implement in order to run an NAE script on an AOS-CX switch?

Question32: An administrator implements interim accounting for guest users so that ClearPass can track the amount of bandwidth that guests upload and download. Guests that abuse bandwidth consumption should be disconnected from the network. The administrator configures the following on the AOS-CX access switches:

After performing this configuration, the administrator notices that guest users that have exceeded the guest bandwidth limit are not being disconnected. Upon further investigation, Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
What is causing this issue?

Question33: Examine the attached exhibit.

The network administrators is trying to add a remote location as area 3 to the network shown in the diagram.
Based on current connection restrictions, the administrator cannot connect area 3 directly to area 0. The network is using AOS-CX switches.
Which feature should the administrator implement to provide connectivity to the remote location?

Question34: An administrator is managing a network comprised of AOS-CX switches deployed at the aggregation layer. The switches are paired in a VSX stack and run the OSPF routing protocol.
