CCNA 1. Network Fundamentals

Which IPV6 address block sends packets to a group address rather than a single address?. 2000::/3. FC00::/7. FE80::/10. FF00::/8.

What is a benefit of using Cisco Wireless LAN Controller?. Central AP management requires more complex configurations. Unique SSIDs cannot use the same authentication method. It supports autonomous and lightweight APs. It eliminates the need to configure each access point individually.

Which network allows devices to communicate without the need to access the Internet?. 172.9.0.0/16. 172.28.0.0/16. 192.0.0.0/8. 209.165.201.0/24.

Refer to the exhibit. Which type of route does R1 use to reach host 10.10.13.10/32?. floating static route. host route. default route. network route.

Refer to the exhibit. Which statement explains the configuration error message that is received?. It is a broadcast IP address. The router does not support/28 mask. It belongs to a private IP address range. It is a network IP address.

Refer to the exhibit. Which prefix does Router 1 use for traffic to Host A?. 10.10.10.0/28. 10.10.13.0/25. 10.10.10.144/28. 10.10.13.208/29.

What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?. The Layer 2 switch drops the received frame. The Layer 2 switch floods packets to all ports excepet the receiving port in the given VLAN. The Layer 2 switch sends a copy of a packet to CPU for destination MAC address learning. The Layer 2 switch forwards the packet and adds the destination MAC address to its MAC address table.

An enginner must configure a /30 subnet between two router. Which usable IP address and subnet mask combination meets this criteria?. interface e0/0 description to HQ-A370:98868 ip address 10.2.1.3 255.255.255.252. interface e0/0 description to HQ-A370:98868 ip address 192.68.1.1 255.255.255.248. interface e0/0 description to HQ-A370:98868 ip address 172.16.1.4 255.255.255.248. interface e0/0 description to HQ-A370:98868 ip address 109.165.201.2 255.255.255.252.

Which IPV6 address type provides communication between subnets and cannot route on the internet?. global unicast. unique local. link-local. multicast.

How do TCP and UDP differ in the way that the establish a connection between two endpoints?. TCP uses synchronization packets, and UDP uses acknowledgment packets. UDP uses SYN, SYNC ACK and FIN bits in the frame header while TCP uses SYN, SYN ACK and ACK bits. UDP provides reliable message transfer and TCP is a connectionless protocol. TCP uses the three-way handshake and UDP dos not guarantee message delivery.

Which statement indentifies the functionality of virtual machines?. Virtualized servers run most efficienly when they are phusically connected to a switch that is separate from the hypervisor. The hypervisor can virtualize physical components including CPU, memory, and storage. Each hypervisor can support a single virtual machine and a single software switch. The hypervisor communicates on Layer 3 without the need for additonal resources.

When configuring IPV6 on an interfacem which two IPV6 multicast groups are joined? (Choose two). 2000::/3. 2002::5. FC00::/7. FF02::1. FF02::2.

A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two). runts. giants. frame. CRC. input errors.

Refer to the exhibit. default gateway. hot IP address. NIC MAC address. NIC vendor OUI. subnet mask.

Which 802.11 frame type is association response?. management. protected frame. control. action.

What are two reansons that cause late collisions to increment on an Ethernet interface? (Choose two). when the sending device waits 15 seconds before sending the frame again. when te cable length limits are exceede. when one side of the connection is configured for half-duplex. when Carner Sense Multiple Access/Collision Detection is used. when a collision occurs after the 32nd byte of a frame has been transmitted.

Which action is taken by a switch port enabled for PoE power classification override?. When a powered device begins drawing power from a PoE switch port a syslog message is generated. As power usage on a PoE switch port is checed data flow to the connected device is temporarily paused. If a switch determines that a device is using less than the minimum configured power it assumes the device has failed and disconnects. If a monitored port exceeds the maximum administrative value for power, the port is a shutdown and err-disabled.

Which command automatically generates an IPV6 address from a specified IPV6 prefix and MAC address of an instance?. ipv6 address dhcp. ipv6 address 2001:DB8:5:112::/64 eui-64. ipv6 address autoconfig. ipv6 address 2001:DB8:5:112::2/64 link-local.

Dran an drop the descriptions of file-transfer protocols from the left on to the correct protocols on the riht. provides reliability when loading and IOS image upon boot up. does not require user authentication. uses port 69. uses ports 20 and 21. uses TCP. uses UDP.

In which way does a spine-and-leaf architecture allow for scalability in a network when additional access ports are required?. A spine switch and a leaf switch can be added with redundant connections between them. A spine switch can be added with at least 40 GB uplinks. A leaf switch can be added with a single connection to a core spine switch. A leaf switch can be added with connections to every spine switch.
