350-601 Practice Test 13 — 15 Questions

Question 1

A UCS administrator needs to replace a failed blade server in a chassis with a new blade. The new blade must automatically receive the same configuration as the failed one. Which feature enables this?

Accepted Answer

Stateless computing using service profiles. Stateless computing via service profiles allows a new blade to be assigned the same profile, automatically applying the configuration.

Answer

Chassis management controller failover

Answer

Automatic firmware synchronization

Answer

UCS Manager auto-discovery

Question 2

An engineer is configuring a UCS service profile for a blade server that will boot from local disk. However, the engineer wants to ensure that if the local disk fails, the server will attempt to boot from the SAN. Which boot policy setting should be used?

Accepted Answer

Set local disk as primary and SAN as secondary. UCS boot policies allow setting the boot order. To attempt local disk first and then SAN if local fails, the policy should have local disk as the primary and SAN as the secondary boot device.

Answer

Set the boot order to SAN first, then local disk

Answer

Configure local disk as the only boot device

Answer

Use PXE boot as the primary

Question 3

A data center architect is designing a spine-leaf network with 40 leaf switches and 4 spine switches. Each leaf has 48 x 25G server-facing ports and 8 x 100G uplinks to the spines. What is the oversubscription ratio from server to spine?

Accepted Answer

1.5:1. The oversubscription ratio is calculated by comparing the total server-facing bandwidth to the total uplink bandwidth. Each leaf switch has 48 x 25G server ports = 1200 Gbps of server-facing capacity, and 8 x 100G uplinks = 800 Gbps of spine-facing capacity. The ratio is 1200:800, which simplifies to 1.5:1, meaning the server-facing side has 1.5 times the bandwidth of the uplinks.

Answer

2:1

Answer

3:1

Answer

4:1

Question 4

A UCS C-series rack server is being integrated into UCS Manager using direct connect mode. Which statement about management connectivity is true?

Accepted Answer

The server is managed by UCS Manager through a dedicated management uplink. In direct connect mode, the C-series server is managed through UCS Manager via a dedicated management connection.

Answer

The server's management traffic passes through the Fabric Interconnects

Answer

The server must be configured with IMC Supervisor

Answer

The server must use CIMC for management and cannot be managed by UCS Manager

Question 5

A data center administrator is configuring a Cisco UCS C-series rack server in standalone mode using CIMC. Which interface must be used to mount an ISO image for OS installation over the network?

Accepted Answer

CIMC web interface (KVM or Virtual Media). CIMC provides virtual media capabilities, allowing remote mounting of ISO images via KVM or virtual media session.

Answer

Cisco IMC Supervisor

Answer

UCS Manager GUI

Answer

UCS Central

Question 6

An engineer is configuring a UCS service profile for a blade server that will use FCoE to connect to a Fibre Channel SAN. What must be configured in the service profile to support FCoE traffic?

Accepted Answer

Configure the vNIC with FCoE personality and specify the FCoE VLAN. To carry FCoE traffic, the vNIC must be configured to use the FCoE VLAN and have the FCoE personality enabled. This allows the adapter to parse FCoE frames.

Answer

Assign a WWPN to the vNIC

Answer

Enable the FCoE flag on the vHBA

Answer

Set the vNIC to use the native VLAN for FCoE

Question 7

An administrator needs to replace a faulty blade server in a UCS chassis. The blade is associated with a service profile that has a persistent WWPN pool. What is the correct procedure to maintain stateless computing?

Accepted Answer

Remove the faulty blade, insert the new blade, and auto-associate the service profile. UCS stateless computing allows a blade replacement without reconfiguration by simply disassociating the service profile from the faulty blade, removing the blade, inserting the new blade, and re-associating the same service profile. The WWPNs from the pool are retained.

Answer

Replace the blade and delete the old service profile to create a new one

Answer

Replace the blade and update the WWPN pool to match the new hardware

Answer

Replace the blade and manually reconfigure the service profile with new WWPNs

Question 8

An organization has deployed a 4-node HyperFlex cluster with all-flash storage and replication factor 3 (RF3). One node fails. How many nodes are required to remain operational for the cluster to continue serving data without interruption?

Accepted Answer

3. For RF3, data is replicated three times. With 4 nodes, if one fails, three remain, which still have all data copies. The cluster remains operational.

Question 9

An organization wants to integrate their UCS C-series rack servers into an existing UCS Manager domain. Which mode should be used to achieve centralized management of the C-series servers through UCS Manager?

Accepted Answer

UCS Managed mode. C-series servers can be managed by UCS Manager when they are in UCS Managed mode, which requires the server to be connected via a Fabric Interconnect and have the appropriate license.

Answer

Direct Connect mode

Answer

Standalone mode

Answer

Cisco IMC Supervisor mode

Question 10

Which component in a UCS domain is responsible for aggregating and forwarding all management traffic between the chassis and the fabric interconnects?

Accepted Answer

System controller (CMC). The system controller (also known as the chassis management controller) in the UCS chassis handles management traffic for the blades, including communication with UCS Manager via the FIs.

Answer

CIMC

Answer

Blade BMC

Answer

IOM (FEX)

Question 11

A data center architect is designing access control for a Cisco ACI fabric. The requirement is to allow HTTP traffic from the web tier (EPG web) to the app tier (EPG app), but deny SSH from the management EPG to the web EPG. Which construct should be used?

Accepted Answer

Create a contract between EPGs with appropriate filters.. In Cisco ACI, contracts are the primary mechanism for enforcing policy-based communication between EPGs. By creating a contract between the web and app EPGs with a filter that permits HTTP (TCP/80), and another contract between management and web EPGs with a filter that denies SSH (TCP/22), the architect can precisely meet both requirements. Contracts allow granular control over which protocols and ports are allowed or denied, making them the correct construct for this access control scenario.

Answer

Use a tenant to separate the EPGs logically.

Answer

Configure a VRF to isolate traffic between EPGs.

Answer

Define a bridge domain with L2 policies.

Question 12

A UCS C-series rack server is to be integrated into UCS Manager. The server will be managed by CIMC and must participate in compute pools. Which operating mode should be configured on the C-series server to allow UCS Manager to discover and manage it?

Accepted Answer

UCS-managed mode. C-series servers can operate in standalone mode (IMC only) or UCS-managed mode. To be managed by UCS Manager, the server must be in UCS-managed mode, which requires enabling UCSM (Cisco UCS Manager) mode in CIMC.

Answer

Cisco IMC Supervisor mode

Answer

Direct connect mode

Answer

Standalone mode

Question 13

What is the purpose of a cluster witness VM in a HyperFlex cluster?

Accepted Answer

To act as a tie-breaker for quorum in cluster splits. The witness VM is used to achieve quorum in a two-node cluster (or to maintain quorum in case of network partitions). It is a lightweight VM that participates in cluster decision-making.

Answer

To host the HyperFlex management interface

Answer

To provide additional storage capacity

Answer

To provide compute resources for the cluster

Question 14

In a UCS B-Series environment, where are vNICs and vHBAs defined to provide network and storage connectivity to a blade server?

Accepted Answer

In the service profile associated with the blade. vNICs and vHBAs are defined in a service profile, which is then applied to a blade server to abstract the hardware identity.

Answer

In the server BIOS settings

Answer

In the I/O Module (IOM) configuration

Answer

In the Fabric Interconnect CLI

Question 15

A network engineer is configuring a UCS service profile for a B-series blade server that will boot from SAN. Which WWPN assignment method should be used to ensure the boot LUN remains accessible if the blade is replaced with another blade of the same type?

Accepted Answer

Assign a dynamic WWPN from a WWPN pool. Stateless computing in UCS relies on persistent WWPNs assigned from a WWPN pool, so when a blade is replaced, the new blade inherits the same WWPNs and can access the same storage LUNs without reconfiguration.

Answer

Set WWPN to the blade's serial number

Answer

Use the WWPN of the Fabric Interconnect port

Answer

Use the built-in WWPN of the mezzanine card
