The network architect is designing an Open Shortest Path First (OSPF) solution and plans to run OSPF on each of the VLAN in switches.

 

Based on the practices, which interface or interfaces should the network architect plan the features on?

Correct Answer:

QUESTION 52

A customer requires high availability, so the network architect is planning two area border (ABRs) for each non-backbone area in the Open Shortest Path First (OSPF) solution. What ensures a loop-free routing environment that meets the customer needs?

 

A.

All ABRs have at least one interface in area 0, and that interface has an IP address that is outside of the range of any summaries for area 0

B.

Each ABR in an area advertises the same summary routes for the area, and each ABR has a null route that matches those summaries

C.

Only one ABR advertise a summary route for each area. For areas with multiple ABRs, each area can include two summaries ranges, and each ABR is configured with one of those ranges

D.

All ABRs in an area apply consistent path costs for their summary routes

 

Correct Answer: A

 

 

QUESTION 53

Which exhibit shows the better Open Shortest Path First (OSPF) area scheme and for which reason?

 

clip_image008

 

A.

Exhibit 1 because it allows the application of access control lists (ACLs) between users and the data center

B.

Exhibit 1 because the campus and data are separate areas

C.

Exhibit 2 because every area has similar numbers of routers

D.

Exhibit 1 because every area has fewer than 50 routers

E.

Exhibit 2 because every area has fewer than 35 routers

 

Correct Answer: B

QUESTION 54

A customer is deploying a mobility solution. The IT staff is not experienced in troubleshooting issues with interference and radio frequency (RF) design, and the customer is worried that the wireless connections will not be stable or will not perform well. Which feature of HP unified Wired-WLAN solutions addresses this customer concern?

 

A.

Hot access controller (AC) backup

B.

Wi-Fi Clear Connect integrated intrusion prevention system (IPS)

C.

Remote-AP capabilities for branch offices

D.

Wi-Fi Clear Connect radio resource management (RRM)

 

Correct Answer: D

QUESTION 55

Refer to the exhibit. A network architect is designing the logical topology for a campus LAN networking solution. The customer requires support for 2400 edge ports, which is provided
by 10 intelligent Resilient Framework (IRF) groups at the access layer. This customer does not have a wireless network nor anticipants adding one in the next two years. However, the customer does want to authenticate users with 802.1X and use the network RADIUS server to divide users from different groups into different VLANs. The customer has three user groups, each of which includes between 600 and 900 users. Additionally, the customer understands that the RADIUS server will require several policies but wants to keep these policies as simple and easy to maintain as possible. How can the network architect ensure that the solution meets the customer needs and also follows best practice?

A.

Assign a /23 subnet to each VLAN so that the VLAN can accommodate the required number of users, even if users connect multiple devices

B.

Plan a different VLAN ID and subnet address for each user group on each access layer IRF group. Either core or access layer routing will work for this solution

C.

Use access layer routing. Assign a different subnet to VLAN2 on one access layer IRF group then the VLAN2 on the another access layer group

D.

Plan a solution for designing dissolvable agents to the endpoints so that they can complete 802.1X authentication seamlessly

Correct Answer: B

 

 

QUESTION 56

An implementation plan should include an agreed-on time for the final rollback decision. What should this decision be scheduled?

 

A.

After the cutover to the new solution and the first set of validation tests and just before the user acceptance tests (UATs)

B.

after the first steps of the rollback plan have been implemented, about ten minutes before the end of the maintenance window

C.

just before the point of no return, which is calculated by subtracting the rollback time from the end of the maintenance window

D.

ten minutes before the end of the maintenance window or one hour into the implementation, whichever occur first

 

Correct Answer: C

 

 

QUESTION 57

HOTSPOT

HP data center access layer can use top of rack (ToR) switches or End of Row (EoR)/ Middle of Row (MoR) switches. Select the design with advantage.

QUESTION 58

A network architect has planned several validation tests and user acceptance tests (UATs) for a new HP solution. In order to ensure meaningful results, what is one step that the network should complete before implementing the new solution?

 

A.

Talk with key authentication to determine valid maintenance windows for the UATs

B.

Plan how long it will take to rollback the new solution of the tests
indicate poor results

C.

Schedule a point of no return, after which results will not be accepted

D.

Run the same tests on the existing network solution

 

Correct Answer: D

 

 

QUESTION 59

A network architect is working with a customer to implement a new network design. The network architect has learned that the company has a legacy application hosted on a number of legacy servers. The legacy application must remain intact and after the new network implementation. As the company plans to continue using it indefinitely. With which stakeholder should the network architect discuss the technical detail of the legacy system and any challenges or specifics about maintaining interoperability?

 

A.

Chief Executive officer (CEO)

B.

Network Architect or Planning Engineer

C.

Chief Information Officer (CIO) or Voice President (VP)/ Director of IT

D.

Chief Financial Officer (CFO) or Voice President (VP)/ Director of Finance

 

Correct Answer: B
