If a network architect is planning a secure device management policy, why would administrators need to generate SSH keys on network infrastructure devices?
To authenticate managers with a more secure method than passwords
To encrypt management traffic and also authenticate managers with asymmetric
To authenticate managers and assign them privileges according to their identity
To encrypt management traffic related to the CLI
A network architect is planning an update of the server access layer in a data center. Currently, the access layer switches have 10G links to distribution layer switches. In the new solution, HP 5930 Switches act as top of rack (ToR) switches with 40G links to core switches.
Which factor must the network architect consider when designing solution?
Whether the data center cabling provides enough fiber strands to the racks to support the 40G links
Whether the new switches 40G transceivers are on the chassis front or back, the transceivers must be on the same side as servers air outtakes
Whether the servers connecting to the new switches use Ethernet Virtual Bridging (EVB)/Virtual Ethernet Port Aggregate (VEPA), which is not compatible with 40G
Whether the servers connecting to the new switches have NICs that support Converged Enhanced Ethernet (CEE)
A network architect has collected data on link utilization. When analyzing link utilization, what is the general guideline?
You upgrade a link that is often used at more than 50 percent utilization
You upgrade a link when it reaches 100 percent utilization
You upgrade a link if it sometimes peaks at more than 50 percent utilization
You upgrade a link when it reaches 25 to 30 percent utilization
Explanation: upgrading links when they reach 50 percent average utilization
What correctly describes one trend that is changing how network architects must design the data center network infrastructure?
Applications are drawing on more and more locally stored data, which causes customers to favor blade servers and blade enclosures
Applications are considering on single, highly available mainframes, driving the need for 10G connections to the server edge
Applications are increasingly virtualized, which requires architects to implement routing at the access layer to segment each rack into its own VLAN
Applications are scaling out across multiple servers, increasing communications between servers distributed across the data center
A network architect is planning an intelligent Resilient Framework (IRF) group. What should the network architect implement to protect against a split IRF group?
Distributed Trunking (DT)
Virtual Router Redundancy Protocol (VRRP)
Multi-Active Detections (MAD)
Rapid Ring Protection Protocol (RRPP)
What is the preferred time for completing racking and labeling of equipment for a new implementation?
After the scheduled outage has begun and initial tests have indicated success
Before the scheduled outage
At any time between the beginning of the scheduled outage and the point of no return
At the beginning of the scheduled outage
A customer has Voice IP (VoIP) phones that support Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED). The phase need to receive their VLAN ID using this protocol. The network architect is proposing HP 5500-48G-PoE+EI switches. Each user computer connects to the phone, which then connects to the Ethernet jack. LLDP is enabled on the switch. Each Edge port is trunk port that permits VLAN 10 (the user VLAN) and VLAN 20 (the voice VLAN).
Which other setting recommended on the edge port?
The voice VLAN is enabled
The PVID is set to VLAN 20
LLDP Cisco Discovery Protocol (CDP) compliance enabled
The LLDP voice VLAN ID is set to 20
A customer wants a simple solution for deploying virtual services at a branch. Which devices support modules running a VMware ESXi hypervisor?
HP 2920 Switch Series
HP MSR30 Router Series
HP 5400 zl Switch Series
HP 7500 Switch Series
HP VSR1000 Virtual Services Routers
Answer: BC Question: 132 Refer to the exhibit.
The exhibit shows a proposed design for a data center network infrastructure. The exhibit shows two racks for simplicity. The data center will actually include more racks.
The customer has these key requirements:
The customer can scale any application and easily install new hardware that supports that application The network supports vMotion for live migration of virtual machine (VMs)
How should the network architect change the proposed design to meet the customer requirements?
Replace the rack servers with blade enclosures
Add more links between the servers and the access layer
Remove routing from the access layer and extend VLANs to multiple racks
Add a distribution layer between the access layer and the core
Answer: D Question: 133 Refer to the exhibit.
The exhibit shows the topology for an enterprise LAN with an on-site data center. The intelligent Resilient
Framework (IRF) group of HP 5500 Series switches supports a group of computers that require very high availability to the data center. Therefore, the customer has requested a backup gigabit fiber link implement Open Shortest Path First (OSPF) in a single area.
Which tasks should the network architect complete to ensure that the HP 5500 IRF group selects the correct path to the data center during normal operation?
Change the reference bandwidth on the VLAN 100 interfaces to 20000
Set the cost on the VLAN 100 interfaces to 2 Set the cost for the VLAN 101 interfaces to 80
Change the reference bandwidth on the VLAN 101 interfaces to 1000
Change the VLAN 101 interfaces as silent interfaces
Change the reference bandwidth to 80000 on all routing devices
