It is disabled by default on all interfaces connected to trunks.

It increases security on the management VLAN.

It increases the potential for MAC address flooding.

It is enabled by default on all VLANs and interfaces.

10 / 20

A wireless access point is needed and must meet these requirements:

"zero-touch" deployed and managed by a WLC
process only real-time MAC functionality
used in a split-MAC architecture

Which access point type must be used?

lightweight

mesh

autonomous

cloud-based

AAA Override and the IP address of the server

12 / 20

Why implement VRRP?

to hand over to end users the autodiscovery of virtual gateways

to leverage a weighting scheme to provide uninterrupted service

to provide end users with a virtual gateway in a multivendor network

to detect link failures without the overhead of Bidirectional Forwarding Detection

15 / 20

What must be considered before deploying virtual machines?

resource limitations, such as the number of CPU cores and the amount of memory

whether to leverage VSM to map multiple virtual processors to two or more virtual machines

support for physical peripherals, such as monitors, keyboards, and mice

location of the virtual machines within the data center environment

16 / 20

What are two features of the DHCP relay agent? (Choose two.)

allows only MAC-to-IP reservations to determine the local subnet of a client

minimizes the necessary number of DHCP servers

assigns DNS locally and then forwards request to DHCP server

permits one IP helper command under an individual Layer 3 interface

is configured under the Layer 3 interface of a router on the client subnet

17 / 20

Which two northbound APIs are found in a software-defined network? (Choose two.)

OpenFlow

SOAP

NETCONF

REST

OpFlex

18 / 20

Which two principles must be considered when using per-hop behavior in QoS? (Choose two.)

Policing is not supported on subinterfaces

Shaping and rate limiting have the same effect.

Shaping levels out traffic bursts by delaying excess traffic.

Policing is performed in the inbound and outbound directions.

Shaping drops excessive traffic without adding traffic delay.

19 / 20

What is the purpose of an ESSID?

It allows multiple access points to provide a common network for client connections.

It provides greater security than a standard SSID.

It supports fast roaming features such as 802. 11r, 802.11k, and 802.11v.

It serves as the wireless MAC address of the access point.

20 / 20

802. 1X authentication

EAPOL-key frame

four-way handshake
