106 Final Practice

A network administrator is configuring an ACL with the command access-list 10 permit 172.16.32.0 0.0.15.255. Which IPv4 address matches the ACE?

172.16.45.2

To enable RIP routing for a specific subnet, the configuration command network 192.168.5.64 was entered by the network administrator. What address, if any, appears in the running configuration file to identify this network?

192.168.5.0

Refer to the exhibit. A small business uses VLANs 8, 20, 25, and 30 on two switches that have a trunk link between them. What native VLAN should be used on the trunk if Cisco best practices are being implemented?

5

Which problem is evident if the show ip interface command shows that the interface is down and the line protocol is down?

A cable has not been attached to the port.

Which three statements accurately describe VLAN types? (Choose three).

A management VLAN is any VLAN that is configured to access management features of the switch. After the initial boot of an unconfigured switch, all ports are members of the default VLAN. An 802.1Q trunk port, with a native VLAN assigned, supports both tagged and untagged traffic.

A network administrator is implementing DHCPv6 for the company. The administrator configures a router to send RA messages with M flag as 1 by using the interface command ipv6 nd managed-config-flag. What effect will this configuration have on the operation of the clients?

Clients must use all configuration information that is provided by a DHCPv6 server.

After sticky learning of MAC addresses is enabled, what action is needed to prevent dynamically learned MAC addresses from being lost in the event that an associated interface goes down?

Copy the running configuration to the startup configuration.

This network has two connections to the ISP, one via router C and one via router B. The serial link between router A and router C supports EIGRP and is the primary link to the Internet. If the primary link fails, the administrator needs a floating static route that avoids recursive route lookups and any potential next-hop issues caused by the multiaccess nature of the Ethernet segment with router B. What should the administrator configure?

Create a fully specified static route pointing to Fa0/0 with an AD of 95.

Which three software packages are available for Cisco IOS Release 15.0?

DATA Security Unified Communications

Which DHCP IPv4 message contains the following information? Destination address: 255.255.255.255 Client IPv4 address: 0.0.0.0 Default gateway address: 0.0.0.0 Subnet mask: 0.0.0.0

DHCPDISCOVER

What is a disadvantage when both sides of a communication use PAT?

End-to-end IPv4 traceability is lost.

Which statement correctly describes how a LAN switch forwards frames that it receives?

Frame forwarding decisions are based on MAC address and port mappings in the CAM table.

A technician is configuring a switch to allow access both to IP phones and to PCs on interface Fa0/12. The technician enters the interface command mls qos trust cos. What is the reason for including that command?

It is used to set the trusted state of an interface to allow classification of traffic for QoS based on the CoS value of the IP phone.

A client is using SLAAC to obtain an IPv6 address for its interface. After an address has been generated and applied to the interface, what must the client do before it can begin to use this IPv6 address?

It must send an ICMPv6 Neighbor Solicitation message to ensure that the address is not already in use on the network.

What two license conditions would be expected on a new Cisco router once the license has been activated? (Choose two.)

License State: Active, In Use License Type: Permanent

Which series of commands will cause access list 15 to restrict Telnet access on a router?

R1(config)# line vty 0 4 R1(config​-line)# access-class 15 in

The buffers for packet processing and the running configuration file are temporarily stored in which type of router memory?

RAM

A network administrator configures a router with the command sequence: R1(config)# boot system tftp://c1900-universalk9-mz.SPA.152-4.M3.bin R1(config)# boot system rom What is the effect of the command sequence?

The router will load IOS from the TFTP server. If the image fails to load, it will load the IOS image from ROM.

Which requirement should be checked before a network administrator performs an IOS image upgrade on a router?

There is sufficient space in flash memory.

A network administrator has entered the following command: ip route 192.168.10.64 255.255.255.192 serial0/0/1 When the network administrator enters the command show ip route, the route is not in the routing table. What should the administrator do next?

Verify that the serial 0/0/1 interface is active and available.

Which type of traffic requires a separate VLAN, strict QoS requirements, and a one-way overall delay of less than 150 ms across the network?

VoIP

What is the name of the layer in the Cisco borderless switched network design that would have more switches deployed than other layers in the network design of a large organization?

access

Which command is issued in the VTY line configuration mode to apply a standard ACL that will control Telnet access to a router?

access-class 11 in

A network engineer is configuring PAT on a router and has issued the command: ip nat source list 1 interface serial 0/1/0 overload Which additional command is required to specify addresses from the 192.168.128.0/18 network as the inside local addresses?

access-list 1 permit 192.168.128.0 0.0.63.255

Which destination do Cisco routers and switches use by default when sending syslog messages for all severity levels?

console

Which type of static route typically uses the distance parameter in the ip route global configuration command?

floating static route

What is a function of the distribution layer?

interconnection of large-scale networks in wiring closets

#show ip route 172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks. Which type of route is this?

A lab in a network management software company is configuring a testing environment to verify the performance of new software with different network connectivity speeds, including FastEthernet, GigabitEthernet, and 10 GigabitEthernet, and with copper and fiber optic connections. Which type of switch should the software company purchase to perform the tests?

Which network design principle focuses on the capability of on-demand seamless network expansion in a switched network?

modularity

A network technician is configuring port security on switches. The interfaces on the switches are configured in such a way that when a violation occurs, packets with unknown source addresses are dropped and no notification is sent. Which violation mode is configured on the interfaces?
