An organization creates an AP architecture that only has self-contained APs without any WLCs. Which architecture type are they using?

  • Autonomous

  • Cloud-based

  • Split-MAC

  • Embedded

  • Mobility Express

Correct answer: Autonomous AP

An autonomous AP architecture uses self-contained access points (APs). The APs handle all of their own functionality without relying on a wireless LAN controller (WLC).

A cloud-based AP architecture uses lightweight APs that are managed from the cloud. A Split-MAC architecture uses lightweight APs with WLCs. An embedded deployment places WLCs with switches. A Mobility-Express deployment has WLCs collocated with APs in branch locations.

An administrator runs the "show ip route" command and sees a line with "O 172.16.4.0 [110/2] via 10.10.10.5, 00:00:15, FastEthernet0/0" in the output. In this output, what is the value for the metric?

  • 2

  • 110

  • O

  • 172.16.4.0

  • 00:00:15

Correct answer: 2

The metric is the second value in brackets. The metric represents the optimum path between multiple paths on the same protocol.

The administrative distance is 110. The routing code is O for OSPF. The prefix is 172.16.4.0. The timer is 00:00:15.

185.

Which three of the following IP addresses are within a private range? (Choose three.)

  • 10.0.1.3

  • 172.30.13.23

  • 192.168.150.1

  • 172.192.1.2

  • 192.16.0.1

There are three private IP address spaces, one in each class of network: Class A, B, and C. The Class A private range is from 10.0.0.0 to 10.255.255.255. The Class B private range is from 172.16.0.0 to 172.31.255.255. The Class C private range is from 192.168.0.0 to 192.168.255.255.

186.

Which two statements are true about administrative distance in routing? (Choose two.)

  • The route with the lowest administrative distance has priority.

  • Static routes have a lower administrative distance than dynamic routes.

  • The route with the highest administrative distance has priority.

  • Dynamic routes have a lower administrative distance than static routes.

The administrative distance is used to determine which route to use between different protocols. The lower the administrative distance, the more priority the route has. Static routes have lower administrative distances than dynamic routes by default.

187.

An administrator needs to set up a new dynamic interface from a WLC's web interface. Which menu tab should they go to in order to add this?

  • Controller

  • Security

  • WLAN

  • Monitor

Correct answer: Controller

The Controller tab can be used to create new interfaces. Enter the name and VLAN number for the interface, then add the IP address, subnet mask, and gateway address.

In the Security tab, an administrator can configure settings that include authentication, certificates, and policies.

The WLAN tab can be used to create new WLANs.

The Monitor tab can let you see the performance of APs.

188.

Which two syslog keywords are considered severe events? (Choose two.)

  • Emergency

  • Alert

  • Critical

  • Error

Syslog has eight severity levels. Levels 0 and 1 are Emergency and Alert, respectively, and are considered severe.

Critical and Error levels are considered impactful.

189.

Which administrative distance represents the best route to a subnet (not an interface)?

  • 1

  • 0

  • 20

  • 100

Correct answer: 1

A lower administrative distance represents the best route. Static routes are the best possible routes to a subnet and have an AD of 1. 

ADs of 0 indicate that a device is directly connected to a router.

190.

Which two terms describe a switch interface that is only assigned to one VLAN? (Choose two.)

  • Access port

  • Static access interface

  • Trunk port

  • Dynamic desirable port

An access port is a port on a switch used to connect to end devices like workstations and servers. Another name for an access port is static access interface. A trunk port creates a link between switches, and a dynamic desirable port is a trunking mode that automatically chooses whether to start trunking.

191.

Which three of the following are PHBs related to QoS? (Choose three.)

  • Classification

  • Marking

  • Shaping

  • Relaying

  • Exclusion

There are several types of Quality of Service (QoS) Per-Hop Behaviors (PHBs) that a router can perform when a packet arrives. These include classification, marking, queuing, congestion, policing, and shaping.

Relaying is related to DHCP. Exclusion is related to configuring DHCP server IP addresses.

192.

Which command would be used to create an OSPF network type connection over an Ethernet WAN?

  • ip ospf network point-to-point

  • ip ospf network broadcast

  • ip ospf priority 2

  • ip ospf hello-interval 30

Correct answer: ip ospf network point-to-point

An Ethernet WAN is a point-to-point network type, so the interface should be configured with the "ip ospf network point-to-point" command. This is more efficient than using a broadcast type connection when there are only two connected devices.

The "ip ospf network broadcast" command sets the network type to broadcast. The "ip ospf priority 2" command sets the interfaces priority for DR/BDR elections. The "ip ospf hello-interval 30" command sets the interval for OSPF Hello messages.

193.

Which three columns will appear when running the command "show mac address-table dynamic?" (Choose three.)

  • Mac Address

  • Type

  • Ports

  • Aging Time

The output from running "show mac address-table dynamic" will include the columns: VLAN, Mac Address, Type, and Ports. To see the aging time, run the command "show mac address-table aging-time."

194.

Which three of the following are considered functions of a standard network management platform? (Choose three.)

  • Network topology mapping

  • Data collection and performance graphing

  • Event handling

  • Connecting multiple remote users to VPNs

  • Distributing connections across servers by using an algorithm

Network management platforms receive and analyze network events from across an enterprise network. The functions a standard network management platform performs include network topology mapping, data collection and graphing, event handling, data browsing, and network discovery.

A VPN concentrator connects multiple remote users to VPNs. A load balancer distributes connections across servers by using an algorithm.

195.

Which feature of Cisco DNA Center lets an administrator see past client performance to compare it to current use?

  • Network time travel

  • Path trace

  • EasyQoS

  • Encrypted traffic analysis

Correct answer: Network time travel

Network time travel is a feature of Cisco DNA Center that lets an administrator see past client performance to compare it to current usage. 

Path trace discovers the path that packets take to their destination based on routing tables. EasyQoS makes quality of service simpler to deploy. Encrypted traffic analysis lets administrators detect threats in encrypted traffic.

196.

Which two of the following are considered Layer 2 security features of Cisco switches? (Choose two.)

  • Port security

  • Dynamic ARP inspection

  • Site-to-site VPN

  • IPv4 ACLs

Port security, dynamic ARP inspection, and DHCP snooping are Layer 2 security features. Port security makes sure that only authorized devices can connect. Dynamic ARP inspection checks if incoming ARP messages are part of an attack.

VPNs operate higher than Layer 2. IPv4 access control lists (ACLs) can filter traffic using IP addresses at Layer 3.

197.

A fashion retail company subscribes to a cloud service to handle their CRM. What type of public cloud model are they using? 

  • SaaS

  • PaaS

  • IaaS

  • FaaS

Correct answer: SaaS

Software as a Service (SaaS) provides a pre-made application hosted on the cloud for customers to utilize. The customer does not need to worry about any of the cloud infrastructure in this model, they just receive the functionality of the cloud software.

Platform as a Service (PaaS) allows a customer to develop their own software in the cloud. Infrastructure as a Service (IaaS) allows customers to lease all the cloud infrastructure they need to accomplish their goals, such as CPU, memory, and storage. Function as a Service (FaaS) allows a customer to host a single function for doing one specific purpose in the cloud.

198.

Which command creates a new VLAN with an ID of 2?

  • vlan 2

  • name 2

  • switchport access vlan 2 

  • show vlan id 2 

Correct answer: vlan 2

The "vlan" command is used to create a new VLAN with the given ID number. This should be done in configuration mode.

The command "name 2" gives a name of 2 to the VLAN. The command "switchport access vlan 2" assigns an interface to VLAN 2. The common "show vlan id 2" displays details about the vlan. 

199.

Which of the following Power over Ethernet standards has 4 wired pairs?

  • UPoE

  • Cisco Inline Power

  • PoE

  • PoE+

Correct answer: UPoE

Power over Ethernet (PoE) has a negotiation process for providing power to devices so that they do not get too much current, which could harm the device. The UPoE standard uses 60 watts and 4 wired pairs. 

Cisco Inline Power uses 7 watts over 2 wire pairs. PoE uses 15 watts over 2 wire pairs. PoE+ uses 30 watts over 2 wire pairs.

200.

What are three methods that routers can use to add routes? (Choose three.)

  • Connected routes

  • Static routes

  • Routing protocols

  • CAM tables

A router has three methods to add IPv4 routes. Connected routes are routes for subnets that are attached to a router interface.  Static routes are added through a configuration command. Routing protocols are used to share route information between routers. A CAM table is used by a switch to send frames to the right interface.
