A technician recently upgraded several pieces of firmware on a server. Ever since the technician rebooted the server, it no longer communicates with the network. Which of the following should the technician do FIRST to return the server to service as soon as possible?
- A. Reseat the NIC
- B. Downgrade the NIC firmware
- C. Replace the NIC
- D. Make sure the NIC is on the HCL
Answer: B
Explanation:
The first thing that the technician should do to return the server to service as soon as possible is downgrade the NIC firmware. Firmware is a type of software that controls the basic functions of hardware devices, such as network interface cards (NICs). Firmware updates can provide bug fixes, performance improvements, or new features for hardware devices. However, firmware updates can also cause compatibility issues, configuration errors, or functionality failures if they are not installed properly or if they are not compatible with the device model or driver version. Downgrading the firmware means reverting to an older version of firmware that was previously working fine on the device. Downgrading the firmware can help resolve any problems caused by a faulty firmware update and restore normal operation of the device.

NEW QUESTION # 70
A company stores extremely sensitive data on an alt-gapped system. Which of the following can Be Implemented to increase security against a potential insider threat?
- A. Two-person Integrity
- B. SIEM
- C. SSO
- D. MFA
- E. Faraday cage
Answer: A
Explanation:
Two-person integrity is a security measure that can be implemented to increase security against a potential insider threat on an air-gapped system. An air-gapped system is a system that is isolated from any network connection and can only be accessed physically. An insider threat is a malicious actor who has authorized access to an organization's system or data and uses it for unauthorized or harmful purposes. Two-person integrity is a system of storage and handling that requires the presence of at least two authorized persons, each capable of detecting incorrect or unauthorized security procedures, for accessing certain sensitive data or material. This way, no single person can compromise the security or integrity of the data or material without being noticed by another person. SSO (Single Sign-On) is a feature that allows users to access multiple applications or systems with one set of credentials, but it does not prevent insider threats. SIEM (Security Information and Event Management) is a tool that collects and analyzes log data from various sources to detect and respond to security incidents, but it does not work on air-gapped systems. A Faraday cage is a structure that blocks electromagnetic signals from entering or leaving, but it does not prevent physical access or insider threats. MFA (Multi-Factor Authentication) is a method that requires users to provide two or more pieces of evidence to verify their identity, such as something they know, something they have, or something they are, but it does not prevent insider threats.

NEW QUESTION # 71
Which of the following ensures a secondary network path is available if the primary connection fails?
- A. Most recently used
- B. Heartbeat
- C. Fault tolerance
- D. Link aggregation
Answer: C
Explanation:
Fault tolerance is the ability of a system to continue functioning in the event of a failure of one or more of its components. Fault tolerance can ensure a secondary network path is available if the primary connection fails. Fault tolerance can be achieved by using redundant components, such as network cards, cables, switches, routers, etc., that can take over the function of the failed component without interrupting the service.

NEW QUESTION # 72
A company uses a hot-site, disaster-recovery model. Which of the following types of data replication is required?
- A. Constant
- B. Incremental
- C. Application consistent
- D. Asynchronous
Answer: A
Explanation:
The type of data replication that is required for a hot-site disaster recovery model is constant. A hot site is a type of disaster recovery site that has fully operational IT infrastructure and equipment that can take over the primary site's functions immediately in case of a disaster or disruption. A hot site requires constant data replication between the primary site and the hot site to ensure that the data is up-to-date and consistent. Constant data replication means that any changes made to the data at the primary site are immediately copied to the hot site without any delay or lag.
NEW QUESTION # 73
A company's IDS has identified outbound traffic from one of the web servers coming over port 389 to an outside address. This server only hosts websites. The company's SOC administrator has asked a technician to harden this server. Which of the following would be the BEST way to complete this request?
- A. Move traffic from port 389 to port 443
- B. Disable port 389 on the server
- C. Enable port 389 for web traffic
- D. Move traffic from port 389 to port 637
Answer: B
Explanation:
The best way to complete the request to harden the server is to disable port 389 on the server. Port 389 is the default port used by LDAP (Lightweight Directory Access Protocol), which is a protocol that allows access and modification of directory services over a network. LDAP can be used for authentication, authorization, or information retrieval purposes. However, LDAP does not encrypt its data by default, which can expose sensitive information or credentials to attackers who can intercept or modify the network traffic. Therefore, port 389 should be disabled on a web server that only hosts websites and does not need LDAP functionality. Alternatively, port 636 can be used instead of port 389 to enable LDAPS (LDAP over SSL/TLS), which encrypts the data using SSL/TLS certificates.
NEW QUESTION # 74
Which of the following BEST describes a warm site?
- A. The site has all infrastructure and live data.
- B. The site has partial infrastructure and some data.
- C. The site has partially redundant infrastructure and no network connectivity
- D. The site has all infrastructure and some data
Answer: B
Explanation:
A warm site is a type of disaster recovery site that has some pre-installed hardware, software, and network connections, but not as much as a hot site. A warm site also has some backup data, but not as current as a hot site. A warm site requires some time and effort to become fully operational in the event of a disaster. A hot site is a disaster recovery site that has all infrastructure and live data, and can take over the primary site's operations immediately. A cold site is a disaster recovery site that has no infrastructure or data, and requires significant time and resources to set up. Reference:

Which of the following is the MOST appropriate scripting language to use for a logon script for a Linux box?
- A. Batch
- B. VBS
- C. Java
- D. PowerShell
- E. Shell
Answer: E
Explanation:
Shell is the most appropriate scripting language to use for a logon script for a Linux box. Shell is a generic term for a command-line interpreter that allows users to interact with the operating system by typing commands and executing scripts. Shell scripts are files that contain a series of commands and instructions that can be executed by a shell. Shell scripts are commonly used for automating tasks, such as logon scripts that run when a user logs on to a system. There are different types of shells available for Linux systems, such as Bash, Ksh, Zsh, etc., but they all share a similar syntax and functionality.
NEW QUESTION # 77
A backup application is copying only changed files each line it runs. During a restore, however, only a single file is used. Which of the following backup methods does this describe?
- A. Open file
- B. Synthetic full
- C. Full Incremental
- D. Full differential
Answer: B
Explanation:
A synthetic full backup is a backup method that describes copying only changed files each time it runs and using only a single file during a restore. A synthetic full backup is a backup approach that involves creating a new full backup by using the previous full backup and related incremental backups. This means that a backup solution does not have to transfer the full amount of data from the source machine and can synthetize the latest incremental backups with the last full backup to create a new full backup. This reduces the backup window and network bandwidth consumption. During a restore, only the latest synthetic full backup file is needed to recover the data. Open file backup is a backup method that allows backing up files that are in use or locked by applications. Full incremental backup is a backup method that involves performing a full backup first and then backing up only the changed files since the last backup. Full differential backup is a backup method that involves performing a full backup first and then backing up only the changed files since the last full backup.
