1. Question 91 · 504 in bank

   Which storage protocol reduces file locks by using leasing?

   • ASMB
   • BNFS 3
   • CNFS 4
   • DCIFS

   Show answer

   Answer: C

   Explanation

   With the NFS version 4 protocol, the support for file locking is part of the NFS protocol. The file locking support is structured so that an RPC callback mechanism is not required. This is a departure from the previous versions of the NFS file locking protocol, Network Lock Manager (NLM). The state associated with file locks is maintained at the server under a lease-based model. https://www.ibm.com/docs/en/zos/2.3.0?topic=control-locking-in-nfs-version-4

3. Question 93 · 504 in bank

   

   Refer to the exhibit. An engineer must distribute all the host ports to use all eight configured FEX uplinks. The solution must minimize disruption if an uplink fails. Which action accomplishes this objective?

   • ASet the pinning max-links value to 8
   • BConfigure the eight uplinks in a port channel
   • CChange the supported FEX type
   • DStatically assign each host interface to a fabric uplink

   Show answer

   Answer: B

   Explanation

   A fabric interface that fails in the port channel does not trigger a change to the host interfaces. Traffic is automatically redistributed across the remaining links in the port channel fabric interface. If all links in the fabric port channel go down, all host interfaces on the FEX are set to the down state.

5. Question 95 · 504 in bank

   A network engineer needs to upgrade the EPLDs of the fabric modules for a Cisco MDS director-class switch. In which order are components reloaded during the process?

   • Aone fabric module at the time
   • Ball fabric modules followed by the entire switching platform
   • Call fabric modules in parallel
   • Done module and one supervisor at the time

   Show answer

   Answer: A

   Explanation

   https://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/sw/6_2/release/notes/epld/epld_rn.html#pgfId-138014 On the Cisco MDS 9513 director switch, there is no command to directly update the fabric module EPLD. The fabric module EPLD is updated as part of the corresponding supervisor module EPLD update, that is, fabric module 1 is updated as part of the slot 7 supervisor module update, and fabric module 2 is updated as part of the slot 8 supervisor module update. For information about how to update Cisco MDS 9513 supervisor modules, see “Installing Supervisor Module EPLDs” section.

   What is a characteristic of EPLD updates on Cisco MDS 9000 Series Switches?

   • AEPLD bundles are released separately from a Cisco MDS NX-OS release
   • BEPLD packages update hardware functionality on a device
   • CEPLD updates are nondisruptive to traffic flow
   • DEPLD updates are installed only via the Cisco DCNM GUI

7. Question 97 · 504 in bank

   The EPLD update of the supervisor module has been scheduled for several Cisco MDS 9000 Series Switches. What will be the impact of the update?

   • AAll traffic is stopped for the duration of the EPLD update and the switch is rebooted after the upgrade is completed.
   • BThe redundant supervisor takes over while the EPLD update is in progress and the switch is rebooted after the upgrade is completed.
   • CAll control plane traffic is stopped for the duration of the EPLD update and the switch remains operational for the duration of the upgrade.
   • DThe redundant supervisor takes over while the EPLD update is in progress and there is no service disruption.

   Show answer

   Answer: A

   Explanation

   An EPLD update of the supervisor module of Fabric Switches (Cisco MDS 9100, Cisco MDS 9200, and Cisco MDS 9300 Series switches) is disruptive since there is no redundant supervisor to take over while the update is in progress. All traffic through the system is stopped while updating and the switch is power cycled after the upgrade has completed. The update may take up to 30 minutes to complete.

9. Question 99 · 504 in bank

   A company is running a pair of Cisco Nexus 7706 Series Switches as part of a data center segment. All network engineers have restricted read-write access to the core switches. A network engineer must add a new FCoE VLAN to allow traffic from servers toward FCoE storage. Which set of actions must be taken to meet these requirements?

   • A1. Assign the network-admin role to a user. 2. Commit the role to the switch to the active user database.
   • B1. Modify a network-operator role and add the required privileges. 2. Assign a VDC-operator role to a user.
   • C1. Create a user-defined role and add the required privileges. 2. Assign a role to a user.
   • D1. Add the required privilege to the VDC-admin role. 2. Commit the changes to the active user database.

   Show answer

   Answer: C

   Explanation

   I´d go for C. Too. User roles contain rules that define the operations allowed for the user who is assigned the role. Each user role can contain multiple rules and each user can have multiple roles. For example, if role1 allows access only to configuration operations, and role2 allows access only to debug operations, then users who belong to both role1 and role2 can access configuration and debug operations. You can also limit access to specific VLANs, virtual routing and forwarding instances (VRFs), and interfaces. The Cisco NX-OS software provides four default user roles: •network-admin—Complete read-and-write access to the entire NX-OS device (only available in the default VDC) •network-operator—Complete read access to the entire NX-OS device (only available in the default VDC) •vdc-admin—Read-and-write access limited to a VDC •vdc-operator—Read access limited to a VDC Note You cannot change the default user roles. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_1/nx-os/security/configuration/guide/sec_nx-os-cfg/sec_rbac.html#wp1431408
