Question 3

Which statement best describes MAC authentication?

The MAC address is used in place of the username in the EAP certificate exchange.

If WEP is used as a key cipher, the MAC address may be used in the key hash.

The MAC address can be spoofed, so it is insecure.

Users will not be able to connect unless some form of encryption is also use

Question 5

Which two statements about the various types or DevOps tools are true? (Choose two)

Puppet requires the installation of a master (server) and agents (clients) architecture for configuring systems.

Salt cannot communicate with clients through general SSH, it use minions client agents only.

Puppet and Chef are written in Python, Python skills are a must to operate these two.

Ansible does not require agent node installation and uses SSH for performing all tasks.

Chef and Puppet are much more attuned to the needs of system administrator

Question 6

You have Cisco Prime Infrastructure deployed on your network in high availability mode. Which statement is true?

The Health Monitor process only runs on the primary server Oracle Recovery Manager runs on both servers and synchronizes the databases when the primary unit fails.

High availability deployments consist of two Cisco Prime Infrastructure servers, a primary and a secondary Each of these servers has an active database and a standby backup copy of the active database Under normal circumstances, both servers are active via a common virtual IP address.

If you choose to deploy the primary and secondary servers on the same IP subnet, you can configure your devices to send notifications to Cisco Prime Infrastructure at a single virtual IP address.

You can trigger a failover manually or have it triggered automatically However, for maximum uptime and no data loss, it is recommended to configure the high availability pair for automatic failover.

Question 7

Which two statements regarding the Service Discovery Gateway feature are true? (Choose two.)

All network segments must be connected directly to the Service Discovery Gateway.

The Service Discovery Gateway can learn services from a single connected segment to build its cache and respond to requests acting as a proxy.

The Service Discovery Gateway feature enables multicast domain name system to operate across Layer 3 boundaries.

Service Discovery Gateway is not aimed at enhancing bring your own device.

The Service Discovery Gateway supports topologies with multiple hops.

5760 WLC Initial Configuration
This section outlines the steps to succesfully configure the 5760 WLC in order to host wireless services.
Configure Setup Script
--- System Configuration Dialog --- Enable secret warning
----------------------------------
In order to access the device manager, an enable secret is required
If you enter the initial configuration dialog, you will be prompted for the enable secret
If you choose not to enter the intial configuration dialog, or if you exit setup without setting the enable secret,
please set an enable secret using the following CLI in configuration mode- enable secret 0 <cleartext password>
----------------------------------
Would you like to enter the initial configuration dialog? [yes/no]: yes
At any point you may enter a question mark \'?\' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets \'[]\'.
Basic management setup configures only enough connectivity for management of the system, extended setup will ask you to configure each interface on the system
Would you like to enter basic management setup? [yes/no]: yes Configuring global parameters:
Enter host name [Controller]: w-5760-1
The enable secret is a password used to protect access to privileged EXEC and configuration modes.
This password, after entered, becomes encrypted in the configuration. Enter enable secret: cisco
The enable password is used when you do not specify an enable secret password, with some older software versions, and some boot images. Enter enable password: cisco

Question 24

Which two statements about the client ARP caching feature, on a Cisco Autonomous AP deployment are true? (Choose two.)

When ARP caching is enabled, the access point forwards all ARP requests through the radio port to associated clients, and the client to which the ARP request is directed responds.

When ARP caching is disabled, the access point responds to ARP requests for associated clients and does not forward requests to clients.

ARP caching on the access point reduces the traffic on your wireless LAN to stopping ARP requests for client devices at the access point.

When ARP caching is enabled, when the access point receives an ARP request for an IP address not in the cache, the access point drops the request and does not forward it.

For client ARP caching, even when the access point has learned the IP addresses for all associated clients, it continues to accept ARP requests.

Question 25

Which statement about configuring the date and time on a wireless LAN controller is true?

When configuring wIPS on the wireless LAN controller you should not use the Universal Time Zone All logs and reports must be time-stamped with the localized time to assist with troubleshooting

You can configure an authentication channel between the controller and the NTP server

To set the wireless LAN controller date and time, only NTP should be used Manually configuring data and time is not supported

As part of their built-in resilience mechanism, Cisco Aironet lightweight access points always connect to the wireless LAN controller independently if the date and time has been set or not

Question 26
