• Question 111:

  Refer to the exhibit.

  

  A customer runs an Online Transaction Processing (OLTP) application on Server1. The application generates a small number of transactions and requires low storage latency. Server2 is a backup server that performs backups twice a day During the backup window, the OLTP application experiences high-latency spikes that affect the application performance The customer must meet these requirements

  1.

  aintain consistent low I/O latency for the OLTP server.

  2.

  uarantee I/O throughput for the OLTP server during backup time

  Correct Answer: D

• Question 112:

  An engineer Installs a B-Series server in a Cisco UCS chassis that contains a pair of UCS-IOM-2208XP I/O modules. The full bandwidth of the I/O module must be utilized. Which two elements should be used in this environment? (Choose two.)

  A. eight twinax cables from each I/O module to each fabric interconnect

  B. four twinax cables from each I/O module to each fabric Interconnect

  C. Cisco UCS VIC 1225

  D. Cisco UCS M81KR

  E. Cisco UCS VIC 1280

  Correct Answer: AE

  2208 has 8 uplinks. VIC 1225 only works on C-Series UCS. M81KR has only 2x10G ports. VIC 1280 has 8x10G ports.

• Question 113:

  A customer needs a design for a new data center network that meets these requirements:

  1.

  Logically partition the environment into separate security domains.

  2.

  Cut costs related to purchasing additional equipment.

  3.

  Separate routing processes, TCAM, QoS tables, and data planes.

  Which technology must be used?

  A. VLAN

  B. vPC

  C. VDC

  D. VRF

  Correct Answer: C

  for item 3 "Separate routing processes, TCAM, QoS tables, and data planes."

• Question 114:

  A storage engineer requires a solution that achieves multiple paths between a server and storage array. The design must support complete traffic isolation and support a 50% growth in the next year.

  Which FCoE solution meets these requirements?

  A. single switch with multiple links

  B. at least two VSANs across the fabric

  C. at least two FC zone sets with multiple zones

  D. single VSAN across the fabric

  Correct Answer: B

• Question 115:

  An engineer enables the HSRP feature on a Cisco Nexus 7000 Series Switch. It must be ensured that the switch manages packets that are sent to the local vPC MAC address, remote vPC MAC address, and HSRP virtual MAC address.

  Which command accomplishes this goal?

  A. peer-switch

  B. peer-gateway

  C. map-server

  D. hsrp preempt

  Correct Answer: D

  vPC Peer Gateway and HSRP

  Some third-party devices can ignore the HSRP virtual MAC address and instead use the source MAC address of an HSRP router. in a vPC environment, the packets using this source MAC address may be sent across the vPC peer link,

  causing a potential dropped packet. Configure the vPC peer gateway to enable the HSRP routers to directly handle packets sent to the local vPC peer MAC address and the remote vPC peer MAC address, as well as the HSRP virtual MAC

  address. See the Cisco Nexus 7000 Series NX-OS Layer 2 Switching Configuration Guide, Release 5.x, for more information on the vPC peer gateway.

• Question 116:

  The user traffic destined to all web servers located in the data center must pass first through a set of firewalls for deep packet inspection. A network architect must design the Cisco Intelligent Traffic Director (ITD) deployment that meets these requirements:

  1.

  The firewalls are connected to a set of two Cisco Nexus switches to provide stateful handling of traffic.

  2.

  The ITD service is provided for inside and outside segments of the firewall. Which ITD deployment mode must be implemented to meet these requirements?

  A. server load-balancing deployment mode

  B. server vPC deployment mode

  C. one-arm deployment mode

  D. sandwich deployment mode

  Correct Answer: C

• Question 117:

  A company runs mission-critical infrastructure in a single data center. Due to business growth It plans to open more data center in the coming years. A network engineer is asked to recommend a network technology for data center interconnection that allows scalability and seamless VM mobility while providing maximum security and fault isolation between data center. Which technology must be used to meet these requirements?

  A. Cloudsec

  B. UDLD

  C. Trustsec

  D. OTV

  Correct Answer: D

• Question 118:

  A database administrator experiences delay when performing storage replication between primary and secondary data centers. The data centers are located 20 kilometers apart and are connected using a 500 Mbps link. The deployment was implemented using an FCIP tunnel and a pair of Cisco MDS 9250 Series Switches. The network engineer decided to enable QoS to prioritize replication traffic.

  Which QoS model must be used to resolve the performance issues?

  A. Resource Reservation Protocol

  B. weighted round robin

  C. differentiated services

  D. strict priority queuing

  Correct Answer: D

• Question 119:

  An engineer is implementing a Cisco UCS environment. The system must aggregate all vNICs into a single policy and consistently enforce node disassociation across the cluster. Which two UCS policies meet these requirements? (Choose two.)

  A. scrub policy

  B. vNIC policy

  C. boot policy

  D. firmware policy

  E. LAN connectivity policy

  Correct Answer: BE

• Question 120:

  The management of the Cisco Nexus switches is provided over an isolated put-of-band network. The VDC feature is configured on the Cisco Nexus core switches. How is out-of-band management access provided for each VDC?

  A. All the VDC have the same out-of-band IP address.

  B. Each VDC has a dedicated out-of-band Ethernet management port.

  C. Each VDC has a unique out-of-band IP address from the same IP subnet.

  D. Each VDC has a unique out-of-band IP address from different IP subnets among VDCs.

  Correct Answer: C

  Virtual Device Contexts (VDC) allow you to carve out multiple virtual switches from a single physical Nexus switch

  Each VDC is logically isolated from every other VDC on a switch. Therefore just like with physical switches, in order to trunk or route traffic between them, physical interfaces and cabling is required to connect two or more VDCs together

  before this can happen.

  A useful VDC feature is that the mgmt0 interface on the Supervisor can be assigned a different IP address by each VDC.

  VDC management can be done via virtualizing the management port so that, each VDC will get logical instance of management port and where we have to provide the separate IP address to each Virtual management Port present in VDC

  from the same subnet
