Answer:
A. PRL
Explanation:
Mobile phone technologies like CDMA , GSM etc, are used by cell/ mobile phone to transmit and receive signals. With the limitation of fluctuation, a mobile phone was made to adapt to this problems, thereby combining this broadbands like CDMA, GSM,4G LTE etc gave rise to PRL (Preferred roaming list) database to hold information needed to establish connection to the correct cell tower for these broadbands.
Answer:
The certification developed by the SANS is GIAC certification .In this there are 3 certification GSEC,GISF and GCED .The description of these certification is given below .
Explanation:
The GIAC certification course is providing the knowledge of the security like cryptography ,networkig knowledge etc .
GSEC:The GSEC Certification is the certification of the security.It simply means this certification certified about the security risk in the computer system .
GISF: This certification gives the knowledge of the networking as well as the security in the computer system also it gives the knowledge of the cryptography.
GCED :This certification is also providing the knowledge of security as well as networking.
Difference between GIAC and InfoSec certifications is given below
- The SANS certification is giving the knowledge about the security risk as well as cryptography by the professional where as the InfoSec certifications providing the knowledge of the hacking by the professional .
- The SANS is including the certification of GIAC certification where as the InfoSec certifications is including the CISSP and SSCP certification .
What was the options they gave you?
Answer: EMI(Electromagnetic interference)
RFI(Radio frequency interference)
Explanation: Electromagnetic interference is the emission of the electromagnetic signal that can disturb the working of the other device.It invokes the disturbance that can create error, under-performance mechanism,distortion etc in the equipment.
Radio-frequency interference(RFI) is the radio-frequency signal that interferes the other device by creating noise and distortion. This leads to breaking of the operation and data error.
Other options are incorrect because cross talk is referred as undesired communication between signal ,attenuation is the degradation in the amplitude of any signal and extended length of cabling is increasing the length of the cable.Thus the correct answer is RFI and EMI.
