1.

Which FCoE component is responsible for the encapsulation and de-encapsulation of Fibre Channel frames in Ethernet?

distributed FCF FCoE node FCoE logical endpoint Fibre Channel forwarder FCoE forwarder

2.

Which item represents the process that allows FCoE multihop using T11 standard FC-BB-5?

distributed FCF FIP proxy N Port proxy FIP snooping

3.

How does an FCoE end node acquire its FCoE MAC address?

server-provided MAC address Fibre Channel name server fabric-provided MAC address FIP proxy

4.

Which statement about implementation of Cisco TrustSec on Cisco Nexus 5546 or 5548 switches are true?

Cisco TrustSec support varies depending on Cisco Nexus 5500 Series Switch model. The hardware is not able to support MACsec switch-port-level encryption based on IEEE 802.1AE. The maximum number of RBACL TCAM user configurable entries is 128k. The SGT Exchange Protocol must use the management (mgmt 0) interface.

5.

After enabling strong, reversible 128-bit Advanced Encryption Standard password type-6 encryption on a Cisco Nexus 7000, which command would convert existing plain or weakly encrypted passwords to type-6 encrypted passwords?

switch# key config-key ascii

switch(config)# feature password encryption aes

switch# encryption re-encrypt obfuscated

switch# encryption decrypt type6

6.

What is the Overlay Transport Virtualization site VLAN used for?

to allow the join interfaces at different sites to communicate to detect devices at the site that are not capable of OTV to allow multiple site AEDs to communicate with each other to detect other OTV edge devices in the site

7.

By default it will take 10 seconds for authentication to fail due to an unresponsive RADIUS server before a Cisco Nexus series switch reverts to another RADIUS server or local authentication. What is one efficient way to improve the reaction time to a RADIUS server failure?

Decrease the global RADIUS retransmission count to 1. Decrease the global RADIUS timeout interval to 5 seconds. Configure the RADIUS retransmission count and timeout interval per server, versus globally. Configure per server a test idle timer, along with a username and password.

8.

When a local RBAC user account has the same name as a remote user account on an AAA server, what happens when a user with that name logs into a Cisco Nexus switch?

The user roles from the remote AAA user account are applied, not the configured local user roles. All the roles are merged (logical OR). The user roles from the local user account are applied, not the remote AAA user roles. Only the roles that are defined on both accounts are merged (logical AND).

9.

Which statement is true if password-strength checking is enabled?

Short, easy-to-decipher passwords will be rejected. The strength of existing passwords will be checked.

Special characters, such as the dollar sign ($) or the percent sign (%), will not be allowed.

Passwords become case-sensitive.

10.

Which statement about RBAC user roles on a Cisco Nexus switch is true?

If you belong to multiple roles, you can execute only the commands that are permitted by both roles (logical AND). Access to a command takes priority over being denied access to a command. The predefined roles can only be changed by the network administrator (superuser). The default SAN administrator role restricts configuration to Fibre Channel interfaces. On a Cisco Nexus 7000 Series Switch, roles are shared between VDCs.
