Question No. 1
1V0-21.20 Exam Question
An administrator would like to create a fault-tolerant ring between three switches within a Layer 2 network. Which of the following Ethernet features should the administrator employ?
A Spanning Tree Protocol
B Open Shortest Path First
C Port mirroring
D An interior gateway protocol
Correct Answer: A. Spanning Tree Protocol
Explanation: Spanning tree protocol(STP) is a layer 2 network protocol used to prevent looping within a Network topology. STP was created to avoid the problems that arise from computers exchanging data on a local area network that contains redundant paths.
It's also very flexible
Question No. 2
1V0-21.20 Exam Question
A company cell phone was stolen from a technician's vehicle. The cell phone has a passcode, but it contains sensitive information about clients and vendors. Which of the following should also be enabled?
A Factory reset
B Autolock
C Encryption
D Two-factor authentication
Correct Answer: D. Two-factor authentication
Explanation: I believe the answer would be D. I don't think factory reset is in reference to Remote Wipe which would be the obvious answer. However with 2FA, brute forcing into the phone would be impossible. Making access to the data impossible depending on what aspects the 2FA uses. It could also be encryption but in my mind if someone can brute force the password the encryption is useless as all of the data will be available in Plaintext form. Correct me if I'm wrong please, this is just my methodology.
