HP HP Certifications HPE6-A73 Questions & Answers

• Question 101:

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

  A. Different priorities

  B. Different area types

  C. Different MTU sizes

  D. Different IP addresses

  E. Different router IDs

  Correct Answer: BC

• Question 102:

  Examine the commands entered on an AOS-CX switch:

  What is true regarding this configuration for traffic received on interface 100?

  A. The default next-hop address supersedes the two preceding next-hop addresses

  B. The traffic is always dropped is the next-hop addresses are unreachable

  C. The traffic will be routed with the IP routing table entries if the next-hop addresses are unreachable

  D. The next-hop address of 1.1.1.1 is overwritten by the next-hop address of 2.2.2.2

  Correct Answer: C

  Explanation: "interface null: equivalent to the policy drop policing action. Any packets matching the class criteria for that policy entry will be dropped and not routed any further." https://www.arubanetworks.com/techdocs/AOS-CX/10.05/ HTML/5200- 7300/index.html#GUID-DC7E5E47-8F31-4DE4-B257-1A68665B2AF4.html More than one next hop can be assigned with an ACL and they work by priority (based on the sequence number: lower sequence number -> higher priority). So next-hop 2.2.2.2 will be used if 1.1.1.1 is not reachable. If both are unreachable, then the packet will be routed looking at the default routing table, if no specific entry will be found, then the pacjet will be routed to the default next hop defined in the ACL.

• Question 103:

  Examine the network exhibit.

  

  A network administrator is implementing OSPF on a VSX pair of aggregation switches:

  Agg1 and Agg2. VLANs 10 and 20 are connected to layer-2 access switches. Agg-1 and Agg-2 are configured as the default gateway for VLANs 10 and 20, with active gateway enabled.

  What is the best practice for configuring OSPF on the aggregation switches and their connection to the Core switch?

  A. Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active gateway for the Layer-3 VLAN.

  B. Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active forwarding for the Layer-3 VLAN.

  C. Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active gateway for the Layer-3 VLAN.

  D. Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active forwarding for the Layer-3 VLAN.

  Correct Answer: A

• Question 104:

  When implementing deficit weighted round robin queuing, what importance does the weight value have?

  A. Prioritizing latency-sensitive traffic

  B. Queue priority in processing traffic

  C. Strict priority queue

  D. Percentage of interface bandwidth

  Correct Answer: B

• Question 105:

  A network administrator is implementing a configuration plan in NetEdit. The administrator used NetEdit to push the configuration plan to the switch. Which option in the NetEdit planning section should the administrator select to save the configuration running on the switch to the startup-config?

  A. EDIT

  B. VALIDATE

  C. COMMIT

  D. DEPLOY

  Correct Answer: C

• Question 106:

  A network engineer is setting up BGP on AOS-CX switches. The engineer is establishing two different eBGP peering's to two different service providers. The engineer has dozens of contiguous C-class public networks that need to be advertised to the two service providers. The engineer manually defines the networks to be advertised individually with the "network" command.

  How can an administrator advertise only a summarized route to the two service providers?

  A. Create a summarized static route and redistribute this into OSPR

  B. Summarize the networks with the "aggregate-address" BGP command

  C. Enable auto-summarization in the IPv4 address family of the BGP configuration

  D. Create a summarized route in OSPF

  Correct Answer: B

• Question 107:

  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?

  A. Not-so-stubby areas

  B. Bidirectional forward detection (BFD)

  C. OSPFv3

  D. Virtual links

  Correct Answer: D

• Question 108:

  A network administrator needs to replace an antiquated access layer solution with a modular solution involving AOS-CX switches. The administrator wants to leverage virtual switching technologies. The solution needs to support high-availability with dual-control planes.

  Which solution should the administrator implement?

  A. AOS-CX 8325

  B. AOS-CX 6300

  C. AOS-CX 6400

  D. AOS-CX 8400

  Correct Answer: C

• Question 109:

  What is correct regarding the tunneling of user traffic between AOS-CX switches and Aruba Mobility Controllers (MCs)?

  A. Uses IPSec to protect the management and data traffic

  B. Uses IPSec to protect the management traffic

  C. Supports only port-based tunneling

  D. Uses the same management protocol as Aruba APs

  Correct Answer: D

  Explanation: because both AP and Switch use PAPI . Moreover in AOS-CX switch currently not support port based tunnel. AOS-CX switch only support User Based Tunnel (UBT)

• Question 110:

  What is a best practice concerning voice traffic and dynamic segmentation on AOS-CX switches?

  A. Controller authentication and user-based tunneling of the voice traffic

  B. Switch authentication and user-based tunneling of the voice traffic

  C. Controller authentication and port-based tunneling of the voice traffic

  D. Switch authentication and local forwarding of the voice traffic

  Correct Answer: D
