Sample Questions
5 sample questions with answers and explanations. The full bank has 700 questions, enough for 7 full-length practice exams.
Preview — answers shown1. Contoso's network team is troubleshooting a connectivity issue where two VLANs on separate switches cannot communicate despite being configured with the same VLAN ID. Traffic between the switches uses an 802.1Q trunk link. Upon investigation, the team discovers that the native VLAN is set to VLAN 1 on one switch and VLAN 99 on the other. What is the MOST likely consequence of this misconfiguration? (Select one!)
ABoth switches will disable the trunk port to prevent security violations
BNative VLAN mismatch causes untagged frames to be delivered to the wrong VLAN, potentially enabling VLAN hopping attacks
CAll trunk traffic will be encrypted, preventing frame delivery
DThe trunk link will automatically negotiate to the higher VLAN number
Explanation
A native VLAN mismatch on an 802.1Q trunk link causes untagged frames sent by one switch on its native VLAN to be received and placed into a different VLAN on the other switch. This means frames sent untagged on VLAN 1 from one switch will be interpreted as VLAN 99 traffic on the other switch, and vice versa. This misconfiguration can cause broadcast storms, connectivity failures, and VLAN hopping attacks where an attacker crafts double-tagged frames to reach VLANs they should not access. Trunk links do not encrypt traffic; 802.1Q trunking adds VLAN tags to frames but provides no encryption. Trunk links do not automatically negotiate native VLAN numbers; this must be manually configured to match on both sides. Switches do not automatically disable trunk ports due to native VLAN mismatches, though some may generate log warnings.
2. A cloud administrator at Contoso discovers that a Terraform plan shows unexpected changes to resources even though no one has modified the Terraform configuration files. The administrator suspects manual changes were made through the cloud provider's web console. What does this situation indicate, and what is the appropriate first action? (Select one!)
AThe Terraform state file is corrupted; restore it from the last backup
BA Terraform module dependency has changed; run terraform init to refresh modules
CThe Terraform provider plugin is outdated; upgrade to the latest version
DConfiguration drift has occurred; review the plan output to identify manually changed resources
Explanation
When terraform plan shows changes despite no modifications to configuration files, this indicates configuration drift — resources were changed outside of Terraform, typically through the cloud console or CLI. The appropriate first action is to review the plan output to identify which resources were manually modified and decide whether to import the changes into the state or revert them. State file corruption would produce errors rather than a clean plan with unexpected changes. An outdated provider plugin would cause syntax or API errors, not phantom resource changes. Module dependency changes would require explicit version updates in configuration files.
3. Contoso Corporation needs to configure network security for their cloud VPC. The security team requires stateless packet filtering at the subnet level that can explicitly deny traffic from known malicious IP ranges, while also maintaining stateful instance-level protection. Which combination of controls should the cloud engineer implement? (Select two!)
Multiple correct answersANetwork Access Control Lists for subnet-level stateless filtering with explicit deny rules
BSecurity groups for instance-level stateful protection with allow-only rules
CA web application firewall for subnet-level packet filtering
DHost-based firewalls installed on each operating system within the instances
ERoute table modifications to block traffic from specific IP ranges
Explanation
Network Access Control Lists (NACLs) provide stateless packet filtering at the subnet level and support both allow and deny rules, enabling explicit blocking of known malicious IP ranges. Because NACLs are stateless, return traffic must be explicitly allowed including ephemeral ports (1024-65535). Security groups operate at the instance level with stateful inspection, meaning return traffic is automatically allowed when an outbound connection is initiated. Security groups only support allow rules with an implicit deny for everything not explicitly allowed. Together, NACLs and security groups provide defense in depth with complementary capabilities. A web application firewall operates at Layer 7 for HTTP/HTTPS traffic, not at the packet-filtering level for all protocols. Host-based firewalls add operational overhead and are not cloud-native VPC controls. Route table modifications control traffic routing paths, not packet-level allow/deny decisions based on source IP.
4. Tailspin Toys is running a SaaS application and has agreed to an SLA guaranteeing 99.99% monthly uptime. The engineering team has set an internal SLO of 99.995% to maintain a safety margin. The monitoring system reports that the current measured uptime is 99.97%. Which statement accurately describes the situation? (Select one!)
AThe SLI of 99.97% violates both the SLO and the SLA, triggering contractual penalties
BThe SLA, SLO, and SLI are all being met because 99.97% exceeds the two-nines threshold
CThe SLO and SLA are identical concepts, so only the SLI measurement matters
DThe SLI of 99.97% is below the SLO of 99.995% but still meets the SLA of 99.99%
Explanation
The SLI (Service Level Indicator) is the actual measurement of 99.97% uptime. The SLO (Service Level Objective) is the internal target of 99.995%. The SLA (Service Level Agreement) is the external contract guaranteeing 99.99%. Since 99.97% is below both the SLO of 99.995% and the SLA of 99.99%, both targets are violated. The SLA violation means contractual penalties may be triggered. SLAs and SLOs are distinct concepts: an SLA is an external contract with financial penalties between provider and customer, while an SLO is an internal engineering target that is typically set higher than the SLA to provide a safety margin. The error budget has been fully consumed in this scenario.
5. A cloud administrator at Northwind Traders is configuring TLS for their customer-facing web application. The security team has mandated the use of the most current TLS version to maximize security. The administrator needs to understand the key improvements over the previous version. Which statements accurately describe advantages of TLS 1.3 over TLS 1.2? (Select two!)
Multiple correct answersATLS 1.3 supports approximately 37 cipher suites compared to only 5 in TLS 1.2, providing greater flexibility
BTLS 1.3 reduces the handshake to 1-RTT with optional 0-RTT session resumption, improving connection speed
CTLS 1.3 makes forward secrecy optional, allowing administrators to choose based on performance needs
DTLS 1.3 removes support for RSA key exchange, eliminating a known vulnerability vector
ETLS 1.3 requires only AEAD cipher suites, supporting 5 approved cipher suites and removing all legacy algorithms
Explanation
TLS 1.3 reduces the connection handshake from 2 round trips (2-RTT) in TLS 1.2 to just 1 round trip (1-RTT), with an optional 0-RTT session resumption for returning clients, significantly improving connection establishment speed. TLS 1.3 also dramatically simplifies the cipher suite landscape by supporting only 5 AEAD (Authenticated Encryption with Associated Data) cipher suites, removing all legacy and vulnerable algorithms that were present in TLS 1.2's approximately 37 cipher suites. The statement about 37 cipher suites in TLS 1.3 reverses the actual numbers since TLS 1.2 has approximately 37 while TLS 1.3 has only 5. Forward secrecy is mandatory in TLS 1.3, not optional, which is a security improvement over TLS 1.2 where it was optional. While TLS 1.3 does remove RSA key exchange, this is accurate but was not one of the two best answers because the cipher suite reduction and handshake improvement are the most impactful and widely tested improvements.
