What are two descriptions of three-tier network topologies? (Choose two.)

A. The distribution layer runs Layer 2 and Layer 3 technologies
B. The network core is designed to maintain continuous connectivity when devices fail
C. The access layer manages routing between devices in different domains
D. The core layer maintains wired connections for each host
E. The core and distribution layers perform the same functions

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.

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

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

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

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.

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.

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

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

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.
