Question 21
Which action is taken by switch port enabled for PoE power classification override?
A. If a monitored port exceeds the maximum administrative value for power, the port is shutdown and err-disabled.
B. When a powered device begins drawing power from a PoE switch port, a syslog message is generated.
C. As power usage on a PoE switch port is checked, data flow to the connected device is temporarily paused.
D. If a switch determines that a device is using less than the minimum configured power, it assumes the device has failed and disconnects it.
Question 22
What occurs to frames during the process of frame flooding?
A. Frames are sent to all ports, including those that are assigned to other VLANs.
B. Frames are sent to every port on the switch that has a matching entry in MAC address table.
C. Frames are sent to every port on the switch in the same VLAN except from the originating port.
D. Frames are sent to every port on the switch in the same VLAN.
Question 23
Which function does the range of private IPv4 addresses perform?
A. allows multiple companies to each use the same addresses without conflicts
B. provides a direct connection for hosts from outside of the enterprise network
C. ensures that NAT is not required to reach the Internet with private range addressing
D. enables secure communications to the Internet for all external hosts
Question 24
Which action must be taken to assign a global unicast IPv6 address on an interface that is derived from the MAC address of that interface?
A. explicitly assign a link-local address
B. disable the EUI-64 bit process
C. enable SLAAC on an interface
D. configure a stateful DHCPv6 server on the network
Question 25
Several new coverage cells are required to improve the Wi-Fi network of an organization. Which two standard designs are recommended? (Choose two.)
A. 5GHz provides increased network capacity with up to 23 nonoverlapping channels.
B. 5GHz channel selection requires an autonomous access point.
C. Cells that overlap one another are configured to use nonoverlapping channels.
D. Adjacent cells with overlapping channels use a repeater access point.
E. For maximum throughput, the WLC is configured to dynamically set adjacent access points to the channel.
Question 26
How do TCP and UDP differ in the way they provide reliability for delivery of packets?
A. TCP does not guarantee delivery or error checking to ensure that there is no corruption of data, UDP provides message acknowledgement and retransmits data if lost.
B. TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking.
C. TCP is a connectionless protocol that does not provide reliable delivery of data; UDP is a connection-oriented protocol that uses sequencing to provide reliable delivery.
D. TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake.
Question 27
What are two differences between optical-fiber cabling and copper cabling? (Choose two.)
A. A BNC connector is used for fiber connections
B. The glass core component is encased in a cladding
C. The data can pass through the cladding
D. Light is transmitted through the core of the fiber
E. Fiber connects to physical interfaces using RJ-45 connections
Question 28
How does CAPWAP communicate between an access point in local mode and a WLC?
A. The access point must not be connected to the wired network, as it would create a loop
B. The access point must be connected to the same switch as the WLC
C. The access point must directly connect to the WLC using a copper cable
D. The access point has the ability to link to any switch in the network, assuming connectivity to the WLC
Question 29
Which IPv6 address block forwards packets to a multicast address rather than a unicast address?
A. 2000::/3
B. FC00::/7
C. FE80::/10
D. FF00::/12
Question 30
What is the difference regarding reliability and communication type between TCP and UDP?
A. TCP is reliable and is a connectionless protocol; UDP is not reliable and is a connection-oriented protocol.
B. TCP is not reliable and is a connectionless protocol; UDP is reliable and is a connection-oriented protocol.
C. TCP is not reliable and is a connection-oriented protocol; UDP is reliable and is a connectionless protocol.
D. TCP is reliable and is a connection-oriented protocol; UDP is not reliable and is a connectionless protocol.
