  1. 350-601 Implementing and Operating Cisco Data Center Core Technologies (DCCOR) VOL3 QUESTION NO: 1 Which multicasting method uses to advertise group memberships through a routing domain by constructing multicast distribution trees? A.Multicast Listener Discovery B.Protocol Independent Multicast C.Source-Specific Multicast D.Any-Source Multicast Answer: D Explanation: PIM is used between multicast-capable routers and advertises group membership across a routing domain by constructing multicast distribution trees. PIM builds shared distribution trees on which packets from multiple sources are forwarded and source distribution trees on which packets from a single source are forwarded. QUESTION NO: 2 Which Layer 2/Layer 3 protocols increase their hello timers to maintain adjacency during the In- Service Software Upgrade (ISSU) process? (Choose two). A.Enhanced Interior Gateway Routing Protocol (EIGRP) B.Border Gateway Protocol (BGP) C.Intermediate System-to-Intermediate System (IS-IS) D.Unidirectional Link Detection (ULD) E.Bidirectional Forwarding Detection (BFD) Answer: D, E Explanation: When you perform an ISSU process, some Layer 2 and 3 protocols will extend their values to accommodate the upgrade. For example, Unidirectional Link Detection (UDLD) and Bidirectional Forwarding Detection (BFD) will increase their hello timers to maintain adjacency during the ISSU process. QUESTION NO: 3 In which of the following scenarios ‘Turn on Locator LED’ action is unavailable during the renumbering of the Cisco UCS Chassis using Cisco UCS Manager? © Copyright Prep Solutions Limited, All rights reserved

  2. A.When the LED on the chassis starts flashing B.When the Locator LED is turned on already C.When the Locator LED has turned, Amber D.When the Locator LED stops flashing Answer: B Reference: https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-manager/GUI- User-Guides/Infrastructure-Mgmt/3- 2/b_UCSM_GUI_Infrastructure_Management_Guide_3_2/b_UCSM_GUI_Infrastructure_Manag ement_Guide_3_2_chapter_0100.html#task_7CE3D4DF1CEF42A2A7BE144FEDF8DAB5 QUESTION NO: 4 Which configuration files can be imported during the backup operation procedure in Cisco UCS Manager? (Choose two). A.Full-state backup file B.System backup file C.System configuration D.Logical configuration E.FSM configuration Answer: C, D Explanation Enable the Import Operation You cannot import a full-state backup file. You can import any of the following configuration files: •All Configuration •System Configuration •Logical Configuration QUESTION NO: 5 What best practices to consider when managing images to upgrade endpoints in a Cisco UCS domain? (Choose two). A.Images are kept in /bootflash partition in the Fabric Interconnect B.If the /bootflash partition exceeds 70% and 90% capacity, faults are raised C.If the /bootflash partition exceeds 97% capacity, faults are raised D.Image packages do not have versions E.Image packages have bifurcated versions © Copyright Prep Solutions Limited, All rights reserved

  3. F.Cisco publishes image packages only Answer: B, D Explanation The upgrade order for the endpoints in a Cisco UCS domain depends on the upgrade path. Cisco maintains a set of best practices for managing firmware images and updates. Here are some best practices to consider when you manage images: •Before you perform firmware updates, use the UCS Manager image management •interfaces to download relevant images to the fabric interconnect. •The Cisco UCS Manager maintains an inventory of available firmware images. •Images are stored in the /bootflash partition in the fabric interconnect. •The /bootflash partition is dedicated solely to firmware images managed by the UCS •Manager. •Each fabric interconnect ships preloaded with one firmware package. •Faults are raised when the /bootflash partition exceeds 70 percent and 90 percent •capacity. •Each image represents an individual firmware package specific to one hardware •component—for example, I/O module image, BMC image, and UCS Manager image. •Multiple images are bundled together to form an image package. •An image package is meant only for ease of distribution and download. •Unlike an individual image, image packages do not have versions. •Cisco publishes both individual images and image packages. QUESTION NO: 6 In which circumstances Cisco NX-OS exports a flow as part of a NetFlow export UDP datagram? A.When you force a flow to export B.When the flow is exported without timeout value C.When the flow is exported as per the flow timeout value that defaults to 20 seconds D.When a flow is created by Netflow export Answer: A Explanation: Cisco NX-OS exports a flow as part of a NetFlow export UDP datagram under the following Circumstances: •Flows are exported periodically per the flow timeout value, which defaults to •ten seconds if not configured. •You have forced the flow to export. © Copyright Prep Solutions Limited, All rights reserved

  4. QUESTION NO: 7 Using OSPFv3, what happens if the receiving MTU is higher than the IP MTU configured on the incoming interface? A.OSPF fails to establish adjacencies B.OSPF establish adjacencies C.OSPF drops the packet as ‘defragment disabled’. D.The dead interval will be set to 100 seconds Answer: A Explanation Use the IP OSPF MTU-ignore command for OSPFv2 or ipv6 OSPF MTU-ignore command for OSPFv3 to disable MTU mismatch detection on an interface. By default, OSPF checks whether neighbors use the same MTU on a common interface. If the receiving MTU is higher than the IP MTU configured on the incoming interface, OSPF does not establish adjacencies. QUESTION NO: 8 Which of the following is a configuration limitation of BFD features? A.NX-OS supports BFD version 2 only B.HSRP for IPv6 is supported with BFD C.BFD supports multi-hop iBGP only D.NX-OS supports IPv4 only Answer: D Reference: https://images10.newegg.com/UploadFilesForNewegg/itemintelligence/Cisco/multicast_cli140 2017439965.pdf QUESTION NO: 9 You are a network administrator at a local data center. You are configuring vPC system priority on LACP to ensure that vPC peer devices are the primary ones on LACP. Which command is used to configure vPC priorities on LACP? A.Role priority priority B.System-priority priority C.Peer-gateway priority D.System-numbers Priority © Copyright Prep Solutions Limited, All rights reserved

  5. Answer: B Reference You should manually configure the vPC system priority when running LACP to ensure that the vPC peer devices are the primary devices on LACP. When you manually configure the system priority, ensure that you configure the same priority value on both vPC peer devices. If these values do not match, vPC will not come up. QUESTION NO: 10 As a network administrator, you are configuring ACI fabric load balancing. You want to use a load balancing option for a network where each flow is assigned to an uplink based on a hash of 5- tuple. The option must provide flow distribution across available links that are roughly even. Which load balancing option should be used? A.Dynamic load balancing B.Dynamic hash load balancing C.Static hash load balancing D.Static redistribution load balancing Answer: C Explanation The ACI fabric provides several load-balancing options for balancing the traffic among the available uplink. Static hash load balancing is the traditional load-balancing mechanism used in networks where each flow is allocated to an uplink based on a hash of its 5-tuple. This load balancing gives a roughly even distribution of flows across the available links. Usually, with a large number of flows, the even distribution of flows results in an even bandwidth distribution. However, if a few flows are much larger than the rest, static load balancing might give suboptimal results.

A.BGP routing protocol B.Virtual router redundancy protocol C.Gateway load balancing protocol D.Hot Standby router protocol © Copyright Prep Solutions Limited, All rights reserved

  6. Answer: D Explanation: Hot Standby Router Protocol (HSRP) is a First Hop Redundancy Protocol (FHRP) that allows a transparent failover of the first hop gateway router. HSRP provides first-hop routing redundancy for IP hosts on Ethernet networks configured with a gateway or default route. You can use HSRP in a group of routers for selecting an active router and a standby router. QUESTION NO: 12 In OSPFv3, Which LSA feature can control and reduce high CPU and buffer usage and allows OSPF to pack multiple LSAs into an OSPF update message? A.Network Summary LSA B.Router LSA C.LSA group pacing D.LSA MaxAge pacing Answer: C Explanation: You can use the LSA group pacing feature to control the flooding rate of LSA updates in your network. LSA group pacing can reduce high CPU or buffer usage. This feature groups LSAs with similar link-state refresh times to allow OSPF to pack multiple LSAs into an OSPF update message. QUESTION NO: 13 On a Cisco Nexus switch, the TACACS+ feature is disabled is disabled by default. Which of the following commands must be used to enable this feature? A.Switch# feature aaa B.Switch# feature tacacs+ C.Switch(config)# feature aaa D.Switch(config)# feature tacacs+ E.Switch(config-aaa)# feature aaa F.Switch(config-aaa)# feature tacacs+ Answer: D QUESTION NO: 14 © Copyright Prep Solutions Limited, All rights reserved
