What is the typical first step in troubleshooting a website returning a 404 error?
Check that the URL is correct and the resource exists.
Restart the web server service.
Flush the DNS cache on the server.
Modify the server's firewall rules.
A 404 error indicates that the resource cannot be found. The first step is to verify the URL and resource path. Restarting services or changing firewall rules is unnecessary before confirming the correct address.
Which DNS record type maps a domain name to an IPv4 address?
A record
CNAME record
MX record
TXT record
An A record maps a hostname directly to its IPv4 address. CNAME creates an alias, MX directs mail, and TXT stores text information.
Which hosting plan is most suitable for a small personal blog with low traffic?
Shared hosting
VPS hosting
Dedicated server
Cloud hosting
Shared hosting is cost-effective and sufficient for low-traffic personal blogs. VPS or dedicated servers provide more resources than needed, and cloud hosting can be more complex to manage.
What basic network utility can you use to check if a server is reachable?
Ping
Traceroute
Nslookup
Netstat
Ping sends ICMP echo requests to test reachability of a host. Traceroute maps the path, nslookup queries DNS, and netstat displays network connections.
Which practice helps secure a hosting environment by encrypting data in transit?
Use SSL/TLS certificates
Implement a web application firewall
Regularly update server software
Enforce strong passwords
SSL/TLS certificates encrypt data between client and server, protecting information in transit. Firewalls, updates, and strong passwords improve security but do not encrypt traffic.
On an Apache web server, which log file typically contains error messages related to failed requests?
error.log
access.log
apache2.conf
.htaccess
Apache writes failed request details and server errors to error.log. The access.log records all requests, while apache2.conf is a configuration file and .htaccess is a directory override file.
Which change to the DNS TTL value will allow DNS record changes to propagate more quickly?
Decrease the TTL value
Increase the TTL value
Set TTL to the maximum allowed
Remove the TTL setting
Lowering the TTL causes caches to expire faster, so updates propagate more quickly. A higher TTL delays refresh, and removing TTL is not a valid configuration.
Which hosting feature automatically adjusts resources to handle sudden traffic spikes?
Auto-scaling
Load balancing
Vertical scaling
DNS failover
Auto-scaling dynamically adds or removes resources based on demand. Load balancing distributes traffic, vertical scaling requires manual resizing, and DNS failover switches IPs on failure.
Which uptime monitoring method uses scripted checks from various geographic locations?
Synthetic monitoring
Real user monitoring
Local ping checks
Server status polling
Synthetic monitoring runs pre-defined transactions from multiple locations to simulate user behavior. Real user monitoring collects data from actual users, and local checks only test from one point.
What is the primary benefit of using a content delivery network (CDN) in web hosting?
Reduced latency by caching content close to users
Increased total storage capacity
Simplified DNS management
Lowered server CPU usage
A CDN caches static assets on edge servers near users to reduce latency. It does not inherently increase storage for the origin server, simplify DNS, or directly lower CPU usage.
In DNS, what does a CNAME record do?
Creates an alias from one domain name to another
Maps a domain to an IPv4 address
Specifies which mail server handles email
Stores arbitrary text data
A CNAME record creates an alias from one hostname to another canonical name. A records map to IPs, MX to mail servers, and TXT for text entries.
Which HTTP status code in the server access log indicates a successful request?
200
404
301
500
A 200 status code means the request succeeded. 404 indicates not found, 301 is a redirect, and 500 is an internal server error.
For PCI-compliant hosting, which security measure is mandatory?
Firewall configuration restricting unauthorized access
Use of plain FTP for file transfers
Storing cardholder data without encryption
Disabling SSL/TLS on the server
PCI standards require properly configured firewalls to limit access. Plain FTP, unencrypted storage, and disabling SSL violate PCI security rules.
When evaluating a VPS hosting plan, which metric indicates guaranteed CPU time?
CPU shares
RAM allocation
Disk IOPS
Network bandwidth
CPU shares define how much processor time the VPS is guaranteed under load. RAM, disk IOPS, and bandwidth measure other resources.
Which security practice directly helps prevent SQL injection attacks?
Sanitizing and validating user inputs
Enabling HTTP compression
Regularly backing up the database
Using a CDN for static content
Sanitizing and validating inputs removes malicious SQL code before it reaches the database. Compression, backups, and CDNs do not address query security.
An Nginx server log shows frequent 504 Gateway Timeout errors. What is the most likely cause?
The upstream application server is not responding in time
DNS TTL is set too high
SSL certificate mismatch
Server CPU usage is at 100% consistently
A 504 Gateway Timeout means the proxy (Nginx) did not receive a timely response from the upstream server. TTL, certificate issues, and CPU load can cause other errors but not a direct gateway timeout.
A company needs DNS to serve different IP addresses based on the user's geographic location. Which technology should be used?
Geo-DNS
Round-robin DNS
Anycast DNS
MX records
Geo-DNS directs queries to different IPs depending on geographic origin. Round-robin distributes evenly, anycast uses the same IP globally, and MX handles email routing.
During load testing, response times spike when concurrent users exceed 1000. Which deployment strategy minimizes downtime while adding capacity?
Blue-green deployment with horizontal scaling
Vertical scaling of the current server live
Lower the DNS TTL and wait
Increase SSH timeout settings
Blue-green deployment adds new instances in parallel then switches traffic, enabling horizontal scaling without downtime. Vertical scaling typically requires a reboot, and DNS or SSH settings do not address capacity.
A web server includes the HSTS header in its responses. What is the main purpose of HSTS?
Enforce use of HTTPS for subsequent requests
Prevent cross-site scripting attacks
Enable header compression
Control DNS failover timing
HSTS (HTTP Strict Transport Security) tells browsers to only use HTTPS for the domain. It does not handle XSS, compression, or DNS behaviors.
In a high-availability web architecture, which strategy provides automatic failover between primary and secondary servers?
DNS failover with health checks
Manual DNS record update
Daily database backups
Local browser caching
DNS failover services monitor health and switch traffic automatically to a secondary server on failure. Manual updates, backups, and caching do not provide instant failover.
