質問 # 15
Which statement about the impact of a rolling EPLD upgrade on a Cisco MDS 9000 Series Switch is true?
- A. All modules on the switch are disrupted.
- B. An EPLD upgrade is nondisruptive.
- C. Only the modules that are being upgraded are disrupted.
- D. The upgrade can be performed from the standby supervisor module.
正解：C
解説：
The statement that is true about the impact of a rolling EPLD upgrade on a Cisco MDS 9000 Series Switch is that only the modules that are being upgraded are disrupted. A rolling EPLD upgrade is a type of EPLD upgrade that allows the user to upgrade one or more modules in a switch without affecting the rest of the modules. The rolling EPLD upgrade requires a module reload for each module that is being upgraded, which causes a temporary disruption of traffic and services on that module. However, the other modules in the switch continue to operate normally and do not require a reload. The other statements are not true because:
* All modules on the switch are not disrupted. As explained above, only the modules that are being upgraded are disrupted, while the other modules are unaffected by the rolling EPLD upgrade.
* An EPLD upgrade is not nondisruptive. An EPLD upgrade is a process that updates the firmware of the electrical programmable logic devices (EPLDs) that provide hardware functionalities in the switch modules. An EPLD upgrade always involves a module reload, which causes a disruption of traffic and services on that module. However, the disruption can be minimized by using the hitless or non-disruptive EPLD upgrade modes, which preserve the forwarding state and configuration of the module during the reload.
* The upgrade cannot be performed from the standby supervisor module. The EPLD upgrade process requires the supervisor module to be in active mode before it can be upgraded. The standby supervisor module must be switched to active mode manually or automatically before the upgrade can begin.

質問 # 16
What happens to the default host firmware policy after a Cisco UCS Manager upgrade?
- A. It is set to match the host firmware policy.
- B. It is replaced by a new default policy without any firmware entries.
- C. It is updated to contain the firmware entries of all the components.
- D. It is assigned to all the service profiles that include a host firmware policy.
正解：B
解説：
After you upgrade Cisco UCS Manager, a new host firmware policy named "default" is created, and is assigned to all service profiles that did not already include a host firmware policy. The default host firmware policy is blank. It does not contain any firmware entries for any components.
This default policy is also configured for an immediate reboot rather than waiting for user acknowledgment before rebooting the servers.

質問 # 18
Refer to the exhibit. A source is sending a multicast traffic stream to the receiver. How is the multicast traffic expected to flow through the network when it reaches a vPC peer?
- A. * The multicast traffic is not replicated to the ports that joined a multicast group (224.0.0.13) or the peer link.
* The multicast traffic stream flows from Agg-1 to Agg-2 over the M1-to-M2 peer link and forwards the traffic over Layer 4 to Access-2. - B. * The multicast traffic is not replicated to the ports that joined a multicast group (224.0.0.13) or the peer link.
* The multicast traffic stream flows over the vPC link to ensure that orphan ports get the multicast stream in failure scenarios. - C. * The multicast traffic is replicated to the ports that joined a given multicast group and the peer link.
* The multicast traffic stream flows over the peer link to ensure that orphan ports receive the multicast stream in failure scenarios. - D. * The multicast traffic is replicated to the ports that joined a given multicast group and the peer link.
* The multicast traffic stream flows from Agg-1 to Agg-2 over the M1-to-M2 peer link and forwards the traffic over Layer 4 to Access-2.

質問 # 19
What is an advantage of NFSv4 over Fibre Channel protocol?
- A. Congestion management
- B. Lossless throughout
- C. Improved security
- D. Uses IP transport
正解：C
解説：
NFSv4 offers several advantages over Fibre Channel protocol, one of which is improved security. NFSv4 is designed to be more secure than its predecessors, providing strong security features that are not inherent in Fibre Channel. It includes mechanisms for authentication, integrity, and privacy, which are part of its standard protocol suite. NFSv4 also integrates well with security infrastructures like Kerberos, allowing for secure, authenticated access to file systems over a network.

質問 # 26
What is the impact of upgrading the firmware of the Cisco UCS Manager?
- A. Fault suppression is triggered when the upgrade process starts.
- B. The UDP packets destined for the primary fabric interconnect are dropped.
- C. The connected user is logged out and the session is ended.
- D. The connectivity to the fabric interconnects using RDP is unavailable.
正解：A
解説：
When upgrading the Cisco UCS Manager firmware, the system implements fault suppression to prevent unnecessary alarms or faults from being raised during the upgrade process. This ensures a smooth upgrade experience by avoiding false-positive alerts that could otherwise be misinterpreted as real issues.
Fault suppression helps maintain operational stability by temporarily hiding expected warnings related to firmware updates. Once the upgrade is complete, normal fault reporting resumes.
質問 # 27
A Cisco UCS user called "Employee1" accidentally changed the boot policy of the Cisco UCS server at the Cisco UCS Manager root level. This change impacted all service profiles and their storage connectivity was lost. The system administrator wants to prevent this issue from recurring in the future. The new security policy mandates that access must be restricted up to the organization level and prevent other users from modifying root policies. Which action must be taken to meet these requirements?
- A. Assign the user "Employee 1" the network-operator role
- B. Assign users to a specific Cisco UCS locale
- C. Define a custom user role and assign it to users
- D. Modify the privilege level assigned to the user
正解：B
質問 # 28

- A. No startup configuration is available.
- B. The license file is missing on the switch.
- C. Bootflash must contain a special directory named POAP with poap.py file.

質問 # 29
Which two settings must be configured before enabling a Cisco UCS Manager domain for Cisco Intersight connectivity? (Choose two.)
- A. SMTP reply-to-address
- B. SMTP servers
- C. NTP servers
- D. DNS servers
- E. syslog redirection
正解：C、D
解説：
Before enabling a Cisco UCS Manager domain for Cisco Intersight connectivity, you must configure the DNS servers and the NTP servers for the domain. The DNS servers are required to resolve the hostname of the Cisco Intersight service (svc.intersight.com) and the NTP servers are required to synchronize the time between the Cisco UCS Manager and the Cisco Intersight service. These settings ensure that the Cisco UCS Manager can establish a secure and reliable connection with the Cisco Intersight service and register the domain with the Cisco Intersight account.
