HP HP Certifications HPE6-A73 Questions & Answers

• Question 1:

  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?

  A. IGMP snooping must be enabled on all interfaces on a switch to intelligently forward traffic

  B. IGMP requires join and leave messages to graft and prune multicast streams between switches

  C. IGMP must be enabled on all routed interfaces where multicast traffic will traverse

  D. IGMP must be enabled on all interfaces where multicast sources and receivers are connected

  Correct Answer: C

• Question 2:

  An administrator will be implementing tunneling between AOS-CX switches and Aruba gateways. Which list of protocols must minimally be allowed by an intermediate firewall between two sets of devices?

  A. IP protocol 50 and UDP 8209

  B. UDP 4500 and IP protocol 47

  C. UDP 8211 and IP protocol 47

  D. UDP 4500 and UDP 8209

  Correct Answer: C

  Explanation: ACSP Study Guide Page 788 - Allow the following protocols/ports

  -PAPI: UDP 8211

  -GRE: Protocoll 47

• Question 3:

  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?

  A. Both 802.1X and captive portal

  B. 802.1X only

  C. Both 802.1X and MAC-Auth

  D. 802.1X, captive portal, and MAC-Auth

  Correct Answer: C

  Explanation: Employees use 802.1x

  The Aruba guest solution uses MAC-auth.

  The Portal is not configured on the switch port.

• Question 4:

  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?

  A. 192.168.1.5

  B. 192.168.2.5

  C. 192.168.3.5

  D. 192 1684 5

  Correct Answer: C

• Question 5:

  An administrator has an AOS-CX switch configured with:

  router ospf 1

  area 0

  area 1 stub no-summary

  It is the only ABR for area 1. The switch has the appropriate adjacencies to routing switches in areas 0 and 1.

  The current routes in each area are:

  Area 0: 5 routes (LSA Type 1 and 2)

  Area 1: 10 routes (LSA Type 1 and 2)

  External routes: 2 (LSA Type 5)

  Based on the above configuration, how many OSPF routes will routing switches see in Area 1?

  A. 15

  B. 6

  C. 11

  D. 12

  Correct Answer: C

• Question 6:

  An administrator has an aggregation layer of 8325CX switches configured as a VSX pair.

  The administrator is concerned that when OSPF network changes occur, the aggregation switches will respond to the changes slowly, and this will affect network connectivity, especially VoIP calls, in the connected access layer switches.

  What should the administrator do on the aggregation layer switches to alleviate this issue?D18912E1457D5D1DDCBD40AB3BF70D5D

  A. Implement route aggregation

  B. Implement bidirectional forwarding detection (BFD)

  C. Reduce the hello and dead interval timers

  D. Implement graceful restart

  Correct Answer: A

  Explanation: "BFD tests the connectivity between two IP addresses in a BFD session. BFD reports when connectivity is lost. The router (or routing switch) can then use that information to take the appropriate actions, depending on the functions to which you have tied BFD"

• Question 7:

  Examine the following AOS-CX configuration:

  

  Based on this configuration, which statement is correct regarding IoT traffic?

  A. If 10.100.1.2 is not reachable, the IoT traffic will be automatically dropped by the switch

  B. If a specific route is not available in the routing table, the traffic will be routed to 10.100.1.2

  C. The next hop of 10.100.1.2 can be one or more hops away from the AOS-CX switch

  D. All routes are ignored in the routing table for IoT traffic, which is routed to 10.100.1.2

  Correct Answer: B

• Question 8:

  An administrator is concerned about the security of the control plane connection between an AOS-CX switch and an Aruba Mobility Controller (MC) when implementing user-based tunneling. How should the administrator protect this traffic?

  A. IPSec with a digital certificate

  B. GRE with a pre-shared key

  C. PAPI with an MD5 pre-shared key

  D. IPSec with a pre-shared key

  Correct Answer: C

• Question 9:

  An administrator in a company of 349 users has a pair of AOS-CX switches with connections to external networks. Both switches are configured for OSPF. The administrator wants to import external routes on both switches, but assigns different seed metrics to the routes, as well as imports them as external type-1 routes.

  What is the best way for the administrator to accomplish this?

  A. Create a route map with the correct route type and metrics

  B. Define the route type and metrics in the OSPF process

  C. Create a classifier policy with the correct route type and metrics

  D. Define a class and policy map with the correct route type and metrics

  Correct Answer: A

• Question 10:

  Which AOS-CX feature is used to prevent head-on-line (HOL) blocking?

  A. VSF

  B. WFQ

  C. VOQ

  D. VSX

  Correct Answer: C
