Which statement is true about implementing QoS in a network?

Voice traffic automatically receives the highest priority.

QoS guarantees enough bandwidth to every application.

QoS increases actual bandwidth on a link to ensure voice quality.

Voice traffic requires priority over other data traffic because it is sensitive to delays.



2
What are two suggested best practices to implement when securing network devices? (Choose two.)

Configure VLAN 1 as the native VLAN.

Disable unused ports on switches.

Enable SSH and disable Telnet.

Consolidate guest traffic and internal employee traffic.

Ensure that logs are stored locally on routers.



3
A new WIC is installed in an available router slot. At what point during the router startup process does the router test the card for hardware problems?

after the configuration from NVRAM is loaded into RAM

when the bootstrap program is loaded into RAM

after the configuration from NVRAM is loaded into ROM

during the power-on self-test (POST)

Refer to the exhibit. What does the JAX router do with traffic that is destined for a web server with an IP address of 128.107.10.24?

The traffic is sent out Serial 0/0/0.

The router sends the traffic out all interfaces other than the one it came in on.

A request is sent to neighboring routers for paths to the 128.107.0.0 network.

The packets are placed into a queue until a better route is discovered via RIP.



5
After an administrator installs a WIC into a two-slot router and issues the show version command, the newly installed interfaces in the WIC cannot be seen in the router output. What is a possible reason why the newly installed interfaces are not displayed in the router output?

The interface is not configured properly.

The WIC was put into slot 0 instead of slot 1.

The WIC was not physically installed in the slot properly.

The show version command cannot be used to validate the presence of installed interfaces.



6


Refer to the exhibit. A network associate is configuring a new router to provide routing between VLANs. The associate removes the router from the box and connects the Fa0/0 interface to a trunking port on the switch. After the configuration is applied to the router, the traffic between VLANs still fails. What is causing this to occur?

The NWRnStick router needs a routing protocol configured.

The NWRnStick router needs additional Fast Ethernet interfaces installed.

The subinterfaces of the NWRnStick router should have IP addresses applied.

All the subinterfaces of the NWRnStick router should be configured in the same VLAN.



7


Refer to the exhibit. What can be concluded from the output that is shown?

MDF_2811 has a MAC address of 2294:300F:0000.

A Cisco 3750 switch is connected to the FastEthernet1/0/1 port on MDF_2811.

MDF_2811 is installed in the main distribution facility on floor 28 of building 11.

Device 3750-24_IDF2 is running Cisco IOS Software Release 12.2(25)SEE2.



8
A network administrator is troubleshooting connectivity problems on a small IPv6 network that consists of two network segments that are connected by a single router. The administrator can ping the IP addresses of local hosts on each segment from the router. Hosts on one network segment cannot successfully ping the IP addresses of hosts on the other network segment. What is the most likely cause of the connectivity problem between the segments?

incorrect VLAN assignments on each segment

broadcast storm that is caused by a malfunctioning NIC on a host

incorrect DNS mappings of host names to IPv6 addresses

IPv6 traffic forwarding not configured on the router



9
A customer has asked a network engineer to prototype the new IP addressing and summarization strategy for a large, multisite network implementation. Which tool is appropriate for testing the complete addressing scheme?

Cisco SDM

network simulation tool

actual network equipment in a lab

current network of the customer



10


Refer to the exhibit. The network administrator is configuring the port security feature on switch SWC. The administrator issued the command show port-security interface fa 0/2 to verify the configuration. What can be concluded from the output that is shown? (Choose three.)

This port is currently up.

The port is configured as a trunk link.

There is no device currently connected to this port.

Three security violations have been detected on this interface.

Switchport mode for this interface is access-mode.

Security violations will cause this port to shut down immediately.



11
During prototype testing, the network designer performs a test to determine the ability of the network to recover from a link or device failure. Which design goal is validated if the test is a success?

scalability

manageability

availability

security



12
A configuration file needs to be loaded into the RAM of a router from a TFTP server. What should an administrator know before accomplishing this task?

the router IP address and the operating system that is used by the TFTP server

the TFTP server IP address and the name of the configuration file on the server

the router IP address and the name of the router configuration file in NVRAM

the TFTP server IP address and the router interface through which the file will be loaded



13
A small bookstore would like to offer wireless connectivity for customers with laptops. Which wireless components or devices will provide connectivity to the customers with the least possible cost to the bookstore?

standalone access points

wireless LAN controllers

standalone lightweight access points

lightweight access point and wireless LAN controller



14
A router has been removed from the network for maintenance. A new Cisco IOS software image has been successfully downloaded to a server and copied into the flash of the router. What should be done before placing the router back into service?

Back up the new image.

Copy the running configuration to NVRAM.

Delete the previous version of the Cisco IOS software from flash.

Restart the router and verify that the new image starts successfully.



15


Refer to the exhibit. What happens if the network administrator issues the commands shown when an ACL called Managers already exists on the router?

The commands overwrite the Managers ACL that is already on the router.

The commands are added at the end of the Managers ACL that is already on the router.

The commands are added at the beginning of the Managers ACL that is already on the router.

The network administrator receives an error stating that the ACL already exists.
