123. Which three statements accurately describe duplex and speed settings on Cisco 2960 switches? (Choose three.)

An autonegotiation failure can result in connectivity issues.

When the speed is set to 1000 Mb/s, the switch ports will operate in full-duplex mode.

The duplex and speed settings of each switch port can be manually configured.

By default, the speed is set to 100 Mb/s and the duplex mode is set to autonegotiation.

By default, the autonegotiation feature is disabled.

124. Refer to the exhibit. A network administrator configures R1 for inter-VLAN routing between VLAN 10 and VLAN 20. However, the devices in VLAN 10 and VLAN 20 cannot communicate. Based on the configuration in the exhibit, what is a possible cause for the problem?

B. The encapsulation is misconfigured on a subinterface.

A. The port Gi0/0 should be configured as trunk port.

C. A no shutdown command should be added in each subinterface configuration.

D. The command interface gigabitEthernet 0/0.1 is wrong.

125. A network administrator uses the spanning-tree portfast bpduguard default global configuration command to enable BPDU guard on a switch. However, BPDU guard is not activated on all access ports. What is the cause of the issue?

PortFast is not configured on all access ports.

BPDU guard needs to be activated in the interface configuration command mode.

Access ports configured with root guard cannot be configured with BPDU guard.

Access ports belong to different VLANs.

128. A WLAN engineer deploys a WLC and five wireless APs using the CAPWAP protocol with the DTLS feature to secure the control plane of the network devices. While testing the wireless network, the WLAN engineer notices that data traffic is being exchanged between the WLC and the APs in plain-text and is not being encrypted. What is the most likely reason for this?

Although DTLS is enabled by default to secure the CAPWAP control channel, it is disabled by default for the data channel.

DTLS only provides data security through authentication and does not provide encryption for data moving between a wireless LAN controller (WLC) and an access point (AP).

DTLS is a protocol that only provides security between the access point (AP) and the wireless client.

Data encryption requires a DTLS license to be installed on each access point (AP) prior to being enabled on the wireless LAN controller (WLC).

129. A new switch is to be added to an existing network in a remote office. The network administrator does not want the technicians in the remote office to be able to add new VLANs to the switch, but the switch should receive VLAN updates from the VTP domain. Which two steps must be performed to configure VTP on the new switch to meet these conditions? (Choose two.)

Configure the new switch as a VTP client.

Configure the existing VTP domain name on the new switch.

Configure an IP address on the new switch.

Configure all ports of both switches to access mode.

130. Refer to the exhibit. Consider that the main power has just been restored. PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request?

It checks the source L2 address in the Ethernet header against the sender L2 address in the ARP body.

It displays the IP-to-MAC address associations for switch interfaces.

It enables portfast on a specific switch interface.

159. What are two characteristics of Cisco Express Forwarding (CEF)? (Choose two.)

This is the fastest forwarding mechanism on Cisco routers and multilayer switches.

Packets are forwarded based on information in the FIB and an adjacency table.

When a packet arrives on a router interface, it is forwarded to the control plane where the CPU matches the destination address with a matching routing table entry.

With this switching method, flow information for a packet is stored in the fast-switching cache to forward future packets to the same destination without CPU intervention.

When a packet arrives on a router interface, it is forwarded to the control plane where the CPU searches for a match in the fast-switching cache.

162. What is an advantage of PVST+?

PVST+ optimizes performance on the network through load sharing.

The switch updates the refresh timer for the entry.

The switch forwards the frame out of the specified port.

The switch replaces the old entry and uses the more current port.

The switch adds a MAC address table entry for the destination MAC address and the egress port.

166. A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?

Segment the LAN into smaller LANs and route between them.

Add more switches so that fewer devices are on a particular switch.

Replace the switches with switches that have more ports per switch. This will allow more devices on a particular switch.

Replace at least half of the switches with hubs to reduce the size of the broadcast domain.

167. What defines a host route on a Cisco router?

An IPv4 static host route configuration uses a destination IP address of a specific device and a /32 subnet mask.

The link-local address is added automatically to the routing table as an IPv6 host route.

A host route is designated with a C in the routing table.

A static IPv6 host route must include the interface type and the interface number of the next hop router.
