Cisco CCIE Data Center Written Set 2

1.

When configuring vPC-HM CDP with multiple links to the same switch, are port-channels required?

Each link between the upstream switch and the VEM is an individual subgroup. Connections that go to the same upstream switch must be configured with the command channel- group mode active. Connections that go to the same upstream switch must be configured with the command channel- group mode passive. With vPC-HM CDP, the user can pin traffic from a specific VM to a specific uplink. Connections that go to the same upstream switch must be configured with the command channel- group mode on.

2.

Consistency checks and compatibility checks are performed before a vPC is created. During a compatibility check, one vPC peer conveys configuration information to the other vPC peer to verify that vPC member ports can actually form a port channel. Which option is considered as a Type-2 misconfiguration?

port MTU mismatch native VLAN mismatch STP interface settings VLAN mismatch

3.

Which PIM mode is supported in Cisco NX-OS?

sparse mode dense mode sparse-dense mode dense-sparse mode

4.

How many ACL capture sessions can be configured on a Cisco Nexus 7000 switch?

ACL capture is not supported on the Cisco Nexus 7000 switch. Only one ACL capture session can be active at any given time in the system across virtual device contexts. Only one ACL capture session can be active in each virtual device context. The number of ACL capture sessions depends on the space that is available within the ACL Ternary Content Addressable Memory. Only one ACL capture session is supported per VLAN.

5.

On a Cisco Nexus 7000 device, on which port type can port security be configured?

Access ports SPAN destination port trunk ports public VLAN-enabled ports

6.

Which statement is true about DHCP snooping on the Cisco Nexus 7000 platform?

DHCP snooping cannot be enabled globally and on a per-VLAN basis. By default, DHCP snooping is disabled globally and on all VLANs. You can enable DHCP snooping on a single VLAN only. For DHCP snooping to function properly, all DHCP servers must be connected to the device through untrusted interfaces.

7.

OTV is a MAC-in-IP method that extends Layer 2 connectivity across a transport network infrastructure. Which three options are high-availability features? (Choose three.)

OTV fast convergence fast failure detection added the track-adjacency-nexthop command to enable overlay route tracking added support for unicast cores using an adjacency server added support for Ipv6 unicast forwarding and multicast flooding across the OTV overlay

8.

What is the default vPC peer-keepalive timeout on the Cisco Nexus 7000 Series switch?

5 seconds 256 milliseconds 500 milliseconds 1 second

9.

Which of the following is a feature of Fabric Extender?

The Fabric Extender provides two user queues for its QoS support, one for all no-drop classes and one for all drop classes. The class-all-flood and class-ip-multicast class maps are used on the Fabric Extender. The Fabric Extender inherits the CoS configured on the upstream switch. For a Cisco Nexus 2248PQ 10GE Fabric Extender, all fabric interfaces can be bundled into a single fabric port channel.

10.

Basic zoning changes are accomplished through the use of four SW_ILS frames. Which option identifies these frames in the correct order?

RCA, UFC, SFC, ACA ACA, RCA, SFC, UFC SFC, UFC, ACA, RCA ACA, SFC, UFC, RCA UFC, SFC, RCA, ACA
