What is the first phase in the standard IT incident response lifecycle?
Recovery
Eradication
Lessons Learned
Identification
Identification is the initial phase where incidents are detected and reported. It sets the foundation for all subsequent response actions.
What command is used on Windows to display the current IP configuration?
ipconfig
nslookup
tracert
ping
The ipconfig command shows network adapter settings including IP addresses on Windows systems. Other commands perform different network diagnostics.
Which password management practice enhances security by requiring a mix of letters, numbers, and symbols?
Set long expiration to 90 days
Enforce password complexity
Use common dictionary words
Share accounts among multiple users
Enforcing password complexity ensures that passwords include varied character types, making them harder to crack. Other options either weaken security or have no impact on complexity.
The principle of least privilege dictates that users should be granted what level of access?
No access unless requested each time
Full administrative access
Read-only access to all systems
Only necessary access to perform their role
Least privilege means users get only the permissions required for their tasks, reducing security risks. Excessive rights increase the potential impact of errors or attacks.
What is the primary purpose of a change management process in IT operations?
To automatically deploy all changes
To formally approve and document system modifications
To bypass testing for faster updates
To allow users to make changes directly
Change management ensures that all changes are reviewed, approved, and documented to minimize risks. It does not remove testing or oversight steps.
Which phase of incident response focuses on removing malware and vulnerabilities from affected systems?
Recovery
Identification
Containment
Eradication
Eradication involves removing malicious code and closing vulnerabilities. Containment isolates the threat, while recovery restores normal operations.
When troubleshooting a network connection issue, what is the first step you should take?
Reset all network devices
Update firmware on the switch
Immediately replace the network card
Verify physical cable connections and link lights
Checking cables and link indicators is the most basic step to rule out hardware connectivity problems. Other actions are secondary once basic checks pass.
Which Linux tool provides a list of active network connections and listening ports?
ping
traceroute
netstat
ssh
Netstat displays active connections and ports. Ping tests reachability, traceroute maps paths, and ssh provides remote access.
In CPU scheduling, which algorithm is best known for allocating equal time slices to each process?
Priority Scheduling
Shortest Job Next
First-Come, First-Served
Round Robin
Round Robin assigns fixed time slices in rotation, promoting fairness. Other algorithms prioritize differently and do not enforce equal slices.
Which backup type copies only the data that has changed since the last full backup?
Mirror backup
Incremental backup
Full backup
Differential backup
Incremental backups capture changes since the last full backup, minimizing storage. Differential backups capture changes since the last full every time.
What is a bastion host in network security?
A cloud storage endpoint
A hardened server exposed to potential attacks for external services
A backup server for internal databases
A mobile device used for penetration testing
A bastion host is deliberately exposed and fortified to handle external traffic securely. It is not a mobile testing device or backup endpoint.
Which tool would you use to capture and analyze network packets on a server?
curl
tcpdump
top
netcat
Tcpdump captures and analyzes packets on the network interface. Netcat streams data, top monitors processes, and curl fetches web resources.
In virtualization, what does "CPU overcommitment" refer to?
Reserving CPU cores exclusively for critical tasks
Allocating dedicated CPUs only when idle
Allocating more virtual CPUs to VMs than physical cores available
Limiting CPU usage per VM
CPU overcommitment means virtual CPUs assigned exceed physical cores, relying on scheduling. The other options describe resource allocation but not overcommitment.
What document is typically submitted to propose a new IT system change?
Service Level Agreement
Incident Report
Request for Change (RFC)
Configuration Item Record
An RFC formally proposes changes for review and approval. SLAs, incident reports, and CI records serve distinct operational roles.
Which security measure helps prevent brute-force login attacks?
Allow unlimited login retries
Disable logging of failed attempts
Use single-factor authentication only
Account lockout policy after failed attempts
Lockout policies stop repeated login attempts after failures, deterring brute-force. Unlimited retries or disabled logging weaken security.
After isolating a compromised server during a ransomware incident, what is the next recommended step?
Delete infected files
Immediately restore from backup
Collect and preserve forensic evidence
Notify end-users to continue work
Preserving evidence enables analysis of the attack vector and supports legal or compliance requirements. Restoration and cleanup come after evidence collection.
To reduce the disk I/O priority of a backup process on Linux, which command should a system administrator use?
ionice
nice
cpulimit
renice
Ionice adjusts I/O scheduling priority, allowing lower-priority I/O processes to yield to more critical operations. Nice and renice affect CPU priorities only.
In configuration management, which principle ensures that applying the same configuration multiple times does not alter the system further after the first application?
Version control
Modularity
Scalability
Idempotency
Idempotency guarantees that repeated configuration runs yield the same state without unintended changes. Other principles support structure but do not address repeatability.
Which cloud resource management strategy automatically adjusts the number of running instances based on current load?
Auto-scaling
Vertical scaling
Manual provisioning
Snapshots
Auto-scaling automatically adds or removes instances according to load metrics. Vertical scaling changes resource size of existing instances, not count.
In a formal change management workflow, which component specifies how to revert changes if they fail?
Impact assessment
Rollback plan
Risk analysis
Implementation schedule
A rollback plan outlines steps to restore the previous state if a change fails. Impact assessments and schedules describe risks and timing, not reversal procedures.
