D. Cloud resources can scale up as needed
Rapid elasticity is a cloud computing characteristic that allows the scaling up and down of cloud-based
applications on an as-needed basis.
Which of the following best describes elasticity in cloud computing?
A. A cloud-based application framework is used to build more complex apps
B. The cloud operates in an internal virtualized data center
C. All cloud storage is managed from a central pool
D. Cloud resources can scale up as needed
B. TXT
The TXT, or text record, can be used in a DNS server to specify the SPF information. The SPF record
documents the list of email servers authorized to send emails for the domain.

Which of the following would be MOST commonly associated with the management interface on a
switch?
A. ST
B. 802.11

D. The DNS servers are faulty
The DNS (Domain Name System) servers are responsible for converting a fully-qualified domain name
(www.google.com) to an IP address. If the DNS servers are not working, then an IP address for a
device cannot be resolved and the communications process can't continue.
A user has reported they can't browse to Google's search page at https://www.google.com. The
workstation IP address is 192.168.1.5, the subnet mask is 255.255.255.0, the default gateway is
192.168.1.1, and the domain name servers are 10.2.2.1 and 10.2.2.2. A technician can successfully ping
the local IP address, the default gateway, and Google's DNS server at 8.8.8.8. Which of the following is
the most likely cause of this issue?
A. The Ethernet adapter's duplex setting is incorrect
, B. The default gateway is faulty
C. The Internet connection is down
D. The DNS servers are faulty
E. The client's default gateway configuration is incorrect
B. Optical drum is not clean
The cleaning process of a laser printer removes any non-used toner from the optical drum after one
cycle of the printing process. If the cleaning process isn't working properly, extra toner will remain on
the drum and can be transferred to the next section of the page output as dots or specs on the page.
A user in the facilities department is having an issue printing their blueprints to a network laser printer.
When they pick up their output, the page contains specks and small dots randomly printed on the page
with the final output. Which of these is the MOST likely cause of this issue?
A. Network is faulty
B. Optical drum is not clean
C. The fuser is not operating
D. Printer is low on toner
A. Enable data caps
Most smartphones include the ability to set limits on how much data is transferred over certain
network types. For example, iOS can be configured to allow or disallow downloads over a cellular
network and can limit the size of downloads if a cellular network is enabled.
A user would like to ensure all apps on their smartphone use 802.11 networking instead of the cellular
network. Which of the following would provide this functionality?
A. Enable data caps
B. Use biometric authentication
C. Synchronize to iCloud
D. VPN client
B. Direct burial
A direct burial cable is designed to be installed in the ground, so it includes waterproof gel to protect
the copper cables. The cables also include a ground wire to support an electrical ground.
A network administrator is installing an Ethernet cable containing gel and a ground wire. Which of the
following would MOST likely describe this cable?
A. Plenum
B. Direct burial
C. Optical
D. Ethernet patch
B. A link-local address would be assigned
If a device is configured to obtain an IP address from a DHCP (Dynamic Host Configuration Protocol)
server and the DHCP server is not available, an APIPA (Automatic Private IP Addressing) address, or
link-local address, would be assigned.
A Windows computer is configured to obtain an IP address automatically. Which of the following would
occur if the automatic assignment process was not working?
