A network technician has used the access-llst 1 permit 172.16.0.0 0.0.0.255 command to configure NAT on an edge router to translate only four networks, 172.16.0.0 /24, 172.16.1.0 /24, 172.16.2.0 /24, and 172.16.3.0 /24.

What defines a two-tier spine-leaf topology?
The Cisco APICs and all other devices in the network physically attach to leaf switches.
A user reports that the workstation cannot connect to a networked printer in the office in order to print a report created with word processing software. Which troubleshooting action by the helpdesk technician would follow the divide-and-conquer approach?
Ask the user to issue the ipconfig command.
Which two statements describe remote access VPNs? (Choose two.)
Client software is usually required to be able to access the network. Remote access VPNs support the needs of telecommuters and mobile users.
What is a difference between the functions of Cloud computing and virtualization?
Cloud computing separates the application from the hardware whereas virtualization separates the OS from the underlying hardware.
Which three statements are generally considered to be best practices in the placement of ACLs? (Choose three.)
Filter unwanted traffic before it travels onto a low-bandwidth link. Place extended ACLs close to the source IP address of the traffic. Place standard ACLs close to the destination IP address of the traffic.
What is correct in relation to NAT for IPv6?
It is a temporary mechanism to assist in the migration from IPv4 to IPv6.
Which QoS mechanism allows delay-sensitive data, such as voice, to be sent first before packets in other queues are sent?
