If a network architect is planning a secure device management policy, why would administrators need to generate SSH keys on network infrastructure devices?

A. To authenticate managers with a more secure method than passwords

B. To encrypt management traffic and also authenticate managers with asymmetric

C. To authenticate managers and assign them privileges according to their identity

D. To encrypt management traffic related to the CLI

A network architect has created a quality of service (QoS) for an HP 5900 Series switch that uses four traffic classes. Class of Service (CoS) 5 for voice traffic. CoS 4 for Video traffic. And CoS 0 for everything else. The switch ports implement strict priority (SP) queuing.

What would be an advantage of enabling weighted fair queuing (WFQ) instead of SP?

A. When congestion occurs, the port will randomly drop traffic in the CoS 3 and CoS 0 queues, preventing TCP synchronization that increase congestion

B. The architect can ensure that voice traffic is always forwarded before bandwidth intensive video traffic

C. The architect can guarantee specific bandwidth to each class but prevent video an SAP applications from starving out other applications entirely

D. When congestion occurs, the port will buffer traffic in lower priority queues rather than drop it immediately as it does with SP queuing

Customer has a virtualized data center Microsoft Hyper-V Windows Server 2012. The customer has provided this information about the Ms:

Each host has a network (Hyper-V virtual switch) that supports VM productions traffic and owns two server 10G NICs.

Each host has a network (Hyper-V virtual switch) that supports management traffic to the parent partition and owns two server Gigabit NICs. Each rack, the network architect plans to deploy two HP 5920 Series switches, acting as an

Intelligent Resilient Framework (IRF) switch.

Which additional information does the architect need in order to plan the connections to each host?

A. Whether the virtual switches use sFlow or Net Stream to load balance traffic over the NICs

B. Whether the virtual switches use Virtual Ethernet Port Aggregator (VEPA) VLAN tagging

C. Whether the virtual switches use generic or dynamic NIC teaming (Link Aggregation Control [(LACP)] and their hashing method

D. Whether the virtual switches support standard Spanning Tree Protocol (STP) or Cisco Per-VLAN Spanning Tree Protocol Plus (PVST+)

Data center includes services within the same VLAN and subnet that communicate with each other multicast application. Variable Internet Group Management Protocol (IGMP) on this VLAN on data center switches?

A. To enforce security boundaries between servers assigned to different multicast groups

B. To eliminate multicast traffic on server ports that have not requested the multicasts

C. To ensure that different applications do not use overlapping multicasts addresses

D. To enable the servers to hear each other's multicast transmission

Refer to the exhibit.

A network architect is proposing an HP 6600 series router at the core of this enterprise customer network. The router runs Border Gateway Protocol (BGP) and announces the customer networks to the internet service provider (ISP). The router also runs Open Shortest Path First (OSPF) to communicate with the rest of the customer network.

What is an appropriate method for the HP 6604 router to advertise routes to the internet to the other routing switches?

A. The route should redistribute BGP routes OSPF. Areas 1 and 2 should be configured as stub areas to filter out the external routes

B. The router should advertise BGP routes into OSPF but filter out all routes except the private network that belongs to the customer

C. The router should redistribute BGP routes into OSPF. The Area Border Routes (ABRs) should summarize those routes for advertisement in areas 1 and 2

D. The router should advertise a default route as an Autonomous System Router (ASBR) summary to the other routing devices in area 0

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?

A. Whether the data center cabling provides enough fiber strands to the racks to support the 40G links

B. 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

C. Whether the servers connecting to the new switches use Ethernet Virtual Bridging (EVB)/Virtual Ethernet Port Aggregate (VEPA), which is not compatible with 40G

D. Whether the servers connecting to the new switches have NICs that support Converged Enhanced Ethernet (CEE)

Refer to the exhibit.

The customer requirements include resilience for branch communications. If anyone link fails, a branch can still reach the main office servers. In addition either one of the 5920 switches at the core of the WAN should be able to fail with branches still maintaining their connections.

What should the network architect include in the design to meet this requirement?

A. A connection directly to an ISP to each branch router, which also requires the OSPF area to become a not so stubby area (NSSA)

B. Virtual Router Redundancy Protocol (VRRP) enabled and configured in the switches in the 5920 IRF group

C. Graceful restart on the 5920 IRF group in standard IETF mode

D. A floating static route on the branch switches to the 5920 IRF group in case the OSPF solution fails

A company recently experienced a data breach when an unauthorized user accessed the network. Which questions should the network architect ask to identify an affective access solution to prevent unauthorized access in the future? (Select two)

A. Do users have legacy device that do not support 802.1X?

B. Does the company have the resources required to train users on remediation services?

C. Does the company's firewall support access control lists (ACL)?

D. Does the company have an existing RADIUS server?

E. Do users devices support Secure Shell (SSH)?
