Cisco CCNP Data Center 300-610 Questions & Answers

• Question 151:

  Refer to the exhibit.

  

  An engineer is configuring a QoS policy with these requirements

  1.

  Match-all AF11 traffic and set it to a DSCP value of 14.

  2.

  The committed rate must be 10 Mbps with a committed burst rate of 1000 ms

  3.

  Drop any AF11 traffic that violates these settings.

  4.

  Any traffic other than af11 must have a DSCP value of 0

  The given class-map configuration already exists.

  Which solution must the engineer use to meet the requirements?

  A. policy-map type qos policy_af11 class class-other match dscp 0

  B. policy-map type qos policy_af11 class class-af11 match other set dscp 0

  C. policy-map type qos policy_af11 class class-default set dscp 0

  D. policy-map type qos policy_af11 class class_af11 set dscp 0

  Correct Answer: C

• Question 152:

  An engineer must design a multitenant solution using Cisco 7709 switches. The solution must support separate routing instances, separate spanning tree domains, and separate firewalls for each tenant. Which solution meets these requirements?

  A. CFS

  B. VDC

  C. vPC

  D. VRF

  Correct Answer: B

• Question 153:

  Refer to the exhibit.

  

  Server 1 fails to connect to the storage array over the Storage Area Network (SAN) of the Cisco MDS 9000 Series Switch. The requirements are to redesign the storage network and keep these considerations in mind:

  1.

  The traffic from each of the server must be redundant and isolated.

  2.

  The design must tolerate hardware and software failures and upgrades of SAN fabric devices. Which action must be taken to meet these requirements?

  A. Enable NPV and F-Port-channel on ports that face Server 1 on the Fibre Channel switch to create redundant paths.

  B. Create a SAN port channel that faces the storage device to sustain a link failure.

  C. Add an additional supervisor to the Fibre Channel switch to support nondisruptive upgrades.

  D. Place an additional Fibre Channel switch to create two physically independent storage fabrics.

  Correct Answer: A

• Question 154:

  Which two methods mitigate congestion in a SAN network? (Choose two.)

  A. Configure ER_RDY to allow splitting of each ISL between switches into separate virtual links.

  B. Use the port-monitor command to detect slow drain devices.

  C. Configure the port channel to enable individual buffer-to-buffer credits.

  D. Configure the port monitor to allow categorization of a specific device as slow.

  E. Configure the flow control for the FC to use R_RDY.

  Correct Answer: AD

  -

  Extended Receiver Ready—This feature allows each ISL between supporting switches to be split into four separate virtual links, with each virtual link assigned its own buffer-to-buffer credits. Virtual link 0 used to carry control traffic, virtual link 1 is used to carry high-priority traffic, virtual link 2 is used to carry slow devices, and virtual link 3 is used to carry normal traffic.

  -

  Congestion Isolation—This feature allows devices to be categorized as slow by either configuration command or by port monitor.

  -

  Port monitor portguard action for Congestion Isolation—Port monitor has a new portguard option to allow the categorization of a device as slow so that it can have all traffic flowing to the device routed to the slow virtual link. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/sw/8_x/config/interfaces/cisco_mds9000_interfaces_config_guide_8x/congestion_avoidance_isolation.html

• Question 155:

  A Cisco engineer is configuring MPLS VPN BGP at a customer site that is connected to the provider site by more than one path MPLS VPN BGP Local Convergence link protection is enabled. After the engineer installs the main forwarding path and the redundant backup path within the BGP, they assign a unique route distinguisher to each VRF table on all PE devices that serve as a backup to the link.

  What is a prerequisite for this local convergence to work?

  A. Interautonomous system option A (back-to-back VRF) is active.

  B. BGP must support lossless switchover between operational paths

  C. IP/GRE is enabled.

  D. The system is performing a PE-CE link protection on both ends

  Correct Answer: D

• Question 156:

  A customer requires a tool to manage Cisco network hardware. The solution must use secure communication using a secure network protocol, support the use of declarative language to manage the state of resources, and periodically pull changes to the controlled nodes.

  Which tool meets these requirements?

  A. Ansible

  B. SaltStack

  C. Puppet

  D. Nomir

  Correct Answer: C

• Question 157:

  An engineer must design a DNS service available to multiple network zones as a shared service. The network zones are deployed as VRFs within the data center network and no firewall is available for communication between VRFs. Which protocol is needed to implement the shared services?

  A. BGP

  B. OSPF

  C. ISIS

  D. VXLAN

  Correct Answer: D

• Question 158:

  An engineer must connect an existing Cisco Fabric Interconnect to an IP-based storage array. The connection be a channel made directly between the fabric interconnect expansion module and the storage array. The engineer must also consider that the environment is running FCoE for storage and uses QoS to prioritize traffic. Which port type should be used to meet these requirements?

  A. Network

  B. Uplink

  C. Appliance

  D. server

  Correct Answer: B

• Question 159:

  An engineer is configuring a Cisco UCS Service Profile template for an environment that will host Windows servers Some of the servers require access to a Fibre Channel storage network The design requires the server HBA to send the maximum number of commands to a Fibre Channel disk using a single transmission

  Which action must be taken to meet these requirements?

  A. Set LUN Queue Depth to 240

  B. Decrease Link Down Timeout to 20.000

  C. Disable 10 Timeout Retry

  D. Increase Max Data Field Size to 2096

  Correct Answer: A
