HP HP Certifications HPE6-A73 Questions & Answers

• Question 81:

  A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server. The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.

  What is correct regarding the ERSPAN session that needs to be established on an AOS- CX switch? (Choose two.)

  A. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected

  B. On the source AOS-CX switch, the destination specified is the administrator's desktop

  C. The encapsulation protocol used is GRE

  D. The encapsulation protocol used is VXLAN

  E. The encapsulation protocol is UDP

  Correct Answer: AC

  Explanation: In AOS CX the remote mirroring is done using a tunnel interface, so the Mirror source and destination must be configured on each Switch. On the source Switch, the source interface (from where the traffic is mirrored) and destination interface (the tunnel interface to where the traffic is sent to). In the destination Switch, the source interface (which would be the tunnel interface (receiving the traffic from the source switch tunnel)) and the destination would be the client where Wireshark enabled client is connected.

• Question 82:

  An administrator wants to implement a virtual switching technology that implements a single control-plane solution. Which S-CX switches would meet these criteria?

  A. All AOS-CX switching platforms

  B. AOS-CX 6300 and 6400 switches

  C. AOS-CX 6300, 6400, and 83xx switches

  D. AOS-CX 6300 switches

  Correct Answer: C

• Question 83:

  An administrator of a company has concerns about upgrading the access layer switches.

  The users rely heavily on wireless and VoIP telephony. Which is the best recommendation to ensure a short downtime for the users during upgrading the access layer switches?

  A. Install the in-service software upgrade (ISSU) feature with clustering enabled

  B. Install AOS-CX 6300 or 6400 switches with always-on POE

  C. Implement VSF on the AOS-CX access switches

  D. Implement VSX on the AOS-CX access switches

  Correct Answer: B

  Explanation: The key is to reduce the impact. VSF or not will have same impact when the switch reboots. But if the switch support always on poe then at least the POE clients will be ready before the switch finish booting up. If you dont have always on POE, then the poe clients will reboot AFTER the switch boots up.

• Question 84:

  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. The administrator is concerned about how long it takes for OSPF to converge when one of the VSX switches has to reboot.

  What should the administrator to do speed up the OSPF convergence of the switch that is rebooting?

  A. Change the VSXISL link from an OSPF broadcast link point-to-point.

  B. Implement graceful restart on the VSX switches and their neighboring OSPF switches.

  C. Decrease the VSX initial synchronization timer on the two VSX switches.

  D. Define non-backbone areas on the VSX switches as totally stubby areas.

  Correct Answer: B

• Question 85:

  What is correct regarding policy-based routing?

  A. Policies can only be applied to routed interfaces.

  B. Policies can be applied inbound and outbound.

  C. Monitoring of policy interfaces occurs every 60 seconds.

  D. Policy actions include routing permitting or dropping traffic.

  Correct Answer: A

• Question 86:

  A switch will apply a device profile to a port based on which pieces of information? (Select two.)

  A. IP header

  B. MAC address

  C. LLDP

  D. User role

  E. 802.1Q

  Correct Answer: AB

• Question 87:

  A company is implementing AOS-CX switches at the access layer. The company wants to implement access control for employees and guests.

  Which security features will require a ClearPass server to be installed and used by the company?

  A. Downloadable user roles

  B. Dynamic segmentation

  C. User-based tunneling (UBT)

  D. Change of authorization (CoA)

  Correct Answer: A

• Question 88:

  Examine the AOS-CS switch output:

  

  Based on this output, what is correct?

  A. 802.1X authentication was successful, but MAC authentication is yet to start

  B. 802.1X authentication occurred and downloadable user roles are deployed

  C. A local user role was deployed using a ClearPass solution

  D. Only 802.1X authentication is configured on the port

  Correct Answer: B

• Question 89:

  An administrator is managing a pair of core AOS-CX switches configured for VSX. Connected to this core are pairs of aggregation layer AOS-CX switches configured for VSX. OSPF is running between the aggregation and core layers. To speed up OSPF convergence, the administrator has configured BFD between the core and aggregation switches.

  What is a best practice the administrator should implement to reduce CPU processing on the switches if a BFD neighbor fails?

  A. Disable ICMP redirects

  B. Implement graceful restart

  C. Increase the BFD echo timers

  D. Increase the VSX keepalive timer

  Correct Answer: A

• Question 90:

  A network administrator is tasked to set up BGP in the company's network. The administrator is defining an eBGP peering between an AOS-CX switch and a directly- connected service provider. The administrator has configured the following on the AOS-CX switch:

  

  However, when using the "show bgp all summary" command, the state does not display "Established" for the eBGP peer. What must the administrator configure to fix this issue?

  A. router bgp 64500 neighbor 192.168.1.1 ebgp-multihop

  B. router bgp 64500 enable

  C. router bgp 64500 address-family ipv4 unicast neighbor 192.168.1.1 activate

  D. router bgp 64500 neighbor 192.168.1.1 update-source loopback0

  Correct Answer: C
