Which of the following types of USB connections can support data rates of up to 480 Mbps?
USB 2.0
USB 1.1
supports 12 Mbps
USB 3.0 and 3.1
define 5 Gbps (SuperSpeed) and 10 Gbps (SuperSpeed+) rates and can deliver up to 4.5 W
of power.
Which cellular technology is comprised of HSPA+ and EV-DO to provide higher data speeds
than previous cellular data protocols?
3G
3G cellular technology
is made up of two different technologies: HSPA+ and EV-DO. HSPA+ (Evolved High-Speed Packet
Access) is a 3G standard used for GSM cellular networks and can support up to a theoretical
download speed of 168 Mbps and a theoretical upload speed of 34 Mbps. In the real world,
, though, HSPA+ normally reaches speeds around 20 Mbps. EV-DO (Evolution-Data Optimized)
is a 3G standard used for CDMA cellular networks and can support up to 3.1 Mbps downloads.
4G cellular technology
is made up of LTE and LTA-A. Long Term Evolution (LTE) is a packet data communications
specification providing an upgrade path for both GSM and CDMA2000 cellular networks. LTE
has a theoretical speed of 150 Mbps and a real-world speed of around 20 Mbps. LTE Advanced
(LTE-A) has a theoretical speed of 300 Mbps and a real-world speed of around 40 Mbps.
5G cellular technology
is made up of three different types: low-band, mid-band, and high-band mmWave technology.
Low-band 5G reaches an average speed of 55 Mbps with a theoretical speed of 150 Mbps. Mid-
band 5G reaches an average speed of 150 Mbps with a theoretical speed of 1.5 Gbps. High-
band 5G reaches an average speed of 3 Gbps with a theoretical speed of up to 70 Gbps.
Which of the following is a security concern with using a cloud service provider and
could result in a data breach caused by data remnants?
Rapid elasticity
Rapid elasticity
can be a security threat to your organization's data due to data remanences. Data remanence
is the residual representation of digital data that remains even after attempts have been made
to remove or erase it. So, when a cloud resource is deprovisioned and returned to the cloud
service provider, it can be issued to another organization for use. If the data was not properly
erased from the underlying storage, it could be exposed to the other organization. For this
reason, all cloud-based storage drives should be encrypted by default to prevent data
remanence from being read by others.
In IPv6, ::1
is the loopback address
-In IPv4, the loopback address is 127.0.0.1.
