Exam Question
1. Which of the following issue would not happen if ECS server is under attack
by hackers?
A. sensitive data leakB. service running on that server is not availableC. physical server damageD. compromise the reputation of service provider on that server
Physical server damage is an issue that is less likely to occur if an ECS server is under attack by hackers. Typically, attacks on ECS servers aim to gain unauthorized access to sensitive data, disrupt services running on the server, and compromise the reputation of the service provider. Physical server damage is a less common outcome of such attacks.
2. In a regular server maintenance operation, the purpose of installing a
patch on the operating system is?
A. to improve server resource usageB. to improve system usabilityC. to enhance system functionalityD. to avoid existing system vulnerabilities being used by some hackers
The purpose of installing a patch on the operating system during a regular server maintenance operation is to avoid existing system vulnerabilities being used by some hackers. Patches are software updates that are designed to fix security vulnerabilities and other bugs in the operating system. Installing patches helps to ensure that the server remains secure and protected against potential security threats. While patches may also improve resource usage, usability, and functionality, their primary purpose in a maintenance operation is to improve security.
3. Which of the following statements are NOT true about 'Server Guard'
remote logon detection functionality?
A. It needs to setup common logon location in 'Server Guard' configurationB. It can detect the attacking tool used by attackerC. It can detect the remote logon used source IP addressD. It can send warning message to 'Server Guard' user
4. If your company's official website is tampered, the consequence of such
attack could NOT be:
A. Website is used for some illegal attemptsB. Public image or reputation of your company is damagedC. Business is impactedD. Physical server is damaged
The consequence of a tampered company website could not be D. Physical server is damaged. However, A, B, and C are all possible consequences of a website being tampered with. If the website is used for illegal purposes, it could damage the company's reputation and lead to a loss of business. Similarly, if the website is defaced or otherwise altered in a negative way, it could damage the company's public image and lead to a loss of trust from customers. Additionally, if the tampering results in the website being unavailable or functioning improperly, it could impact the company's ability to conduct business online and result in financial losses.
5. Which of the following shell command can be used to check disk usage in a
Linux OS ECS
A. df -hB. echo $(path)C. free -mD. ps-e-o
6.Which of the following benefit cannot be provided by 'Server Guard"?
A. lower the risk of sensitive data leakB. improve the usage of system resourceC. lower the cost of security protectionD. get instant alerts after attacks are detected
7. If your company has a lot of employees who would try to simultaneously
access ECS server protected by 'Server Guard' using your company's intranet,
the 'Sever Guard' may mistakenly identify those access requests as attacks.
Which of the following methods is the best way to solve this problem?
A. set a highly complexed administrator passwordB. change the rule of security group to unblock all company internal ipsC. add those IPs which need to access ECS server into 'Server Guard' logon white listD. ask employees to access that ECS server not very frequently
The best way to solve the problem of 'Server Guard' mistakenly identifying access requests from company employees as attacks is to use option C. Adding the IPs of the employees who need to access the ECS server into the 'Server Guard' logon white list will allow their access requests to bypass the security measures and be granted access to the server.
8. When 'Server Guard' detects remote logon behavior, what information will
be shown on 'Server Guard' console?
A. Illegal Logon!B. Migrated Already!C. Logon Successfully!D. Remote Logon Detected!
9. Which of the following statements is the possible reason that might lead
to system vulnerabilities?
A. software logic flaw or mistakes made during software development cycleB. hardware devices are not up to dateC. system administrator didn't follow the operation manual exactlyD. The proprietary software that is safer than open source one should be installed
The possible reason that might lead to system vulnerabilities is option A, software logic flaw or mistakes made during software development cycle. Software vulnerabilities can occur due to errors or flaws in the software design or code, which can be exploited by attackers to gain unauthorized access or cause damage to the system. Hardware devices that are not up to date (option B) can also pose security risks, but this is not a common reason for system vulnerabilities. Option C, system administrators not following the operation manual exactly, can potentially lead to security issues, but it is not a major reason for system vulnerabilities. Option D, the proprietary software being safer than open source software, is not necessarily true as both types of software can have vulnerabilities and security risks, and the security of the software depends on various factors such as how it is developed, configured, and used.
10. Which command in Redhat Linux shell can be used to check if some
specific string is included in a bunch of text files?
