HP HP Certifications HPE6-A73 Questions & Answers

• Question 21:

  What is required when implementing captive portal an AOS-CX switches?

  A. Certificate installed on the switch

  B. Web server running on the switch

  C. Device fingerprinting

  D. AAA server

  Correct Answer: D

• Question 22:

  What is correct regarding multicasting and AOS-CX switches?

  A. IGMP snooping is disabled, by default, on Layer-2 VLAN interfaces

  B. IGMP query functions are enabled, by default, on Layer-2 VLAN interfaces

  C. IGMP snooping is enabled, by default, on Layer-3 VLAN interfaces

  D. IGMP-enabled AOS-CX switches flood unknown multicast destinations

  Correct Answer: A

• Question 23:

  An administrator creates an ACL rule with both the "count" and "log" option enabled. What is correct about the action taken by an AOS-CX switch when there is a match on this rule?

  A. By default, a summarized log is created every minute with a count of the number of matches

  B. Logging will not include certificate and TLS events, but counting will

  C. The "count" and "log" options are processed by the AOS-CX switch's hardware ASIC

  D. The total in the "log" record and the count could contain different rule matching statistics

  Correct Answer: D

  Explanation: From the "AOS-CX 10.08 ACLs and Classifier Policies Guide" : "You may see a minor discrepancy between the ACL logging statistics and the hit counts statistics due to the time required to record the log message."

• Question 24:

  Examine the following AOS-CX switch configuration:

  

  Which access control entries would allow web traffic to the web servers 10.1.0.100 and 10.1.1.100?

  A. permit tcp servers eq 80

  B. permit tcp any 10.1.0.100 0.0.1.0 eq 80

  C. permit tcp any 10.1.0.100/10.1.1.100 eq 80

  D. permit tcp any 10.1.0.100/255.255.254.255 eq 80

  Correct Answer: B

• Question 25:

  How does PIM build the IP multicast routing table to route traffic between a multicast source and one or more receivers?

  A. It uses the unicast routing table and reverse path forwarding (RPF)

  B. It uses IGMP and calculates a shortest path tree (SPT)

  C. It uses the shortest path first (SPF) algorithm derived from link state protocols

  D. It uses the Bellman-Ford algorithm derived from distance vector protocols

  Correct Answer: A

  Explanation: "PIM also relies on the unicast routing tables to identify the path back to a multicast source. This routing method is known as reverse path forwarding (RPF). The unicast routing protocols create the unicast routing tables. With this information, PIM sets up the distribution tree for the multicast traffic.

• Question 26:

  When implementing user-based tunneling on an AOS-CX switch, which component defines the primary and backup Aruba gateways?

  A. Transit VLAN

  B. Gateway role

  C. Server group

  D. Zone

  Correct Answer: D

• Question 27:

  How does an administrator install a script and create an agent and actions for the Network Analysis Engine running on AOS-CX switches?

  A. Access the switches' command-line interface.

  B. Access the switches' web user interface

  C. Use Aruba Central's web user interface

  D. Use the NetEdit web user interface

  Correct Answer: B

• Question 28:

  What is correct regarding the operation of VSX and multicasting with PIM-SM routing configured?

  A. Each VSX peers runs PIM and builds its own group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN

  B. Each VSX peers runs PIM and creates a shared group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing

  C. Each VSX peers runs PIM and builds its own group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing

  D. Each VSX peers runs PIM and creates a shared group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN

  Correct Answer: A

  Explanation: "both VSX switches as a PIM Designate Router (DR). One node is the actual DR, the other node is the proxy DR." "Only the actual DR performs multicast routing and forward traffic destined to groups to its downstream VLANs in the data-path." https://www.arubanetworks.com/techdocs/AOS-CX/10.07/HTML/5200- 7888/Content/Chp_Pre_tra_loss/ip-mul-rou-10.htm

• Question 29:

  An administrator is supporting a network with the access layer consisting of AOS-CX 6300 and 6400 switches. The administrator needs to quickly deploy Aruba IAPs and security cameras in the network, ensuring that the correct QoS and VLAN settings are dynamically applied to the switch ports. Currently, switches are not configured to do device authentication, and no authentication server exists in the network.

  Which AOS-CX feature should the administrator use to dynamically assign the policy settings to the correct switch ports?

  A. Device profiles

  B. Change of authorization

  C. Dynamic segmentation

  D. Voice VLANs

  Correct Answer: A

• Question 30:

  What is correct regarding the configuration of ACLs on AOS-CX switches?

  A. Statements with the log keyword are always processed by the switch CPU.

  B. Standard ACLs are used to match on routes when performing route distribution.

  C. Wildcard masks are used to match on a range of IP addresses.

  D. Numbers 100 through 199 and 2000 through 2999 are used when creating extended ACLs.

  Correct Answer: C
