Linux Foundation Cilium Certified AssociateCCA Sample Questions (Q27-Q32):

NEW QUESTION # 27
What is the correct statement about the masquerading feature?

A. The iptables-based masquerading is the most efficient Implementation.
B. The eBPF-based masquerading is supported on all kernel versions.
C. It is comparable to Destination Network Address Translation (DNAT).
D. It replaces the source IP of traffic leaving the cluster to the node's IP address.

Answer: D

Explanation:
Technical explanation
Masquerading performs source network address translation for qualifying traffic that leaves the cluster.
Because pod addresses are often private and not routable by the external network, Cilium replaces the pod's source address with an address belonging to the egress node. Return traffic can then reach that node, which reverses the translation and delivers the response to the originating pod. B correctly summarizes this behavior.
Masquerading is a form of SNAT, not DNAT. DNAT modifies the destination address, commonly to direct incoming traffic toward another endpoint, so C is incorrect.
Cilium documents its eBPF-based masquerading implementation as the more efficient implementation. The iptables version is the legacy alternative, making A false. Conversely, eBPF masquerading depends on appropriate kernel eBPF capabilities and Cilium's BPF NodePort functionality. It cannot be assumed to work on every kernel version, so D is false. The legacy iptables implementation is the mode documented as broadly working across kernel versions.
Cilium can exclude natively routable CIDRs from masquerading, and administrators may configure separate IPv4 and IPv6 masquerading behavior.

NEW QUESTION # 28
What is true about Layer 7 protocol visibility in Cilium?

A. It can be enabled by deploying a standard Kubernetes network policy.
B. DNS visibility in available in the ingress direction only.
C. It results in traffic being proxied through an Envoy instance.
D. It supports any Layer 7 protocols, including SSH, Telnet and FTP.

Answer: C

Explanation:
Technical explanation
Layer 7 protocol visibility redirects traffic matching the relevant L7 rules to Cilium's node-local proxy, which is Envoy. Envoy parses supported application protocols and supplies the resulting request or response metadata to Cilium's observability pipeline. Therefore, C correctly identifies the architectural consequence of enabling this visibility.
The feature requires L7 proxy support and an appropriate CiliumNetworkPolicy containing Layer 7 rules. A standard Kubernetes NetworkPolicy is limited to Layer 3 and Layer 4 concepts and cannot express Cilium's HTTP, DNS, or generic application-protocol rules, so B is incorrect.
A is also incorrect. DNS policy and visibility are commonly applied to pod egress queries, and Cilium's model is not restricted to ingress-only DNS visibility. D overstates protocol coverage. Cilium supports defined L7 parsers and policy types-most prominently HTTP, DNS, Kafka, and supported generic Envoy- based protocols-but it does not promise arbitrary visibility for every application protocol. SSH, Telnet, and FTP cannot simply be assumed to receive native semantic parsing.
An operational caveat is that L7 visibility rules also affect policy enforcement: they are not merely passive packet logging instructions.

NEW QUESTION # 29
What is a correct statement related to BIG TCP, an eBPF-based feature in Cilium?

A. While BIG TCP increases the transactions count, it causes higher latency between pods.
B. BIG TCP addresses the limitation in the size of the packets, caused by the 16-bit length field in the IP header.
C. BIG TCP requires updating the Maximum Transmission Unit (MTU) across the network.
D. BIG TCP is incompatible with features like GRO (Generic Receive Offload) and TSO (Transmit Segmentation Offload).

Answer: B

Explanation:
Technical explanation
BIG TCP permits the Linux networking stack to process packets larger than the traditional approximately 64- KiB limit represented by the IP length field while the packets remain inside the host. IPv6 BIG TCP uses a temporary Hop-by-Hop header carrying the larger internal length, while IPv4 BIG TCP sets tot_len to zero and uses the socket buffer length internally. Before transmission, packets are segmented into sizes suitable for the physical network. C therefore identifies the problem BIG TCP addresses.
Option A is false because Cilium's documentation explicitly states that BIG TCP does not require network- interface MTU changes. The larger objects exist inside the software networking stack and are segmented before appearing on the wire.
Option B reverses the intended performance effect. Larger internal GSO and GRO packets reduce repeated stack traversal, lowering CPU utilization and generally improving throughput and latency. Option D is also false: Generic Segmentation Offload and Generic Receive Offload are fundamental to BIG TCP's operation.
Cilium increases their maximum sizes when BIG TCP is enabled. The source mentions TSO, but the documented mechanism is principally described through GSO and GRO.

NEW QUESTION # 30
What does this Egress Gateway policy achieve?

Cilium Egress Gateway policy exhibit

A. It would cause all traffic originating from pods with the org: empire and class: nediabot labels in the default namespace and destined to 192.168.19.0/24 to be routed through the gateway node with the node.kubernetes.io/name: egress-node label, which will then DN AT said traffic with the 10.168.60.100 egress IP
B. It would cause all traffic sent to pods with the org: empire and class: mediabot labels In the default namespace and destined to 192.168.19.9/24 to be routed through the gateway node with the node.
kubemetes.io/name: egress-node label, which will then DNAT said traffic with the 19.168.69.199 egress IP
C. It would cause all traffic sent to pods with the org: empire and class: mediabot labels in the default namespace and destined to 192.168.10.0/24 to be routed through the gateway node with the node.
kubernetes.io/name: egress-node label, which will then SNAT said traffic with the 10.168.60.180 egress IP
D. It would cause all traffic originating from pods with the org: empire and class: mediabot labels in the default namespace and destined to 192.168.19.0/24 to be routed through the gateway node with the node.kubemetes.io/name: egress-node label, which will then SNAT said traffic with the 10.168.60.100 egress IP

Answer: D

Explanation:
Cilium's official documentation confirms that a CiliumEgressGatewayPolicy selects traffic originating from matching pods , routes traffic destined for the configured destinationCIDRs through the selected egress gateway node, and SNATs that traffic using the configured egressIP.

NEW QUESTION # 31
Among the definitions provided for the entities host, remote-node, cluster, and all, which description is accurate in the context of Cilium network policy?

A. The cluster entity represents the kube-apiserver in a Kubernetes cluster. This entity represents both deployments of the kube-apiserver: within the cluster and outside of the cluster
B. The all entity corresponds to all endpoints outside of the cluster. Allowing to all Is identical to allowing to CIDR 0.0.0.0/0.
C. The remote-node entity represents endpoints not managed by Cilium. Unmanaged endpoints are considered part of the cluster and are included in the cluster entity.
D. The host entity Includes the local host. This also includes all containers running in host networking mode on the local host.

Answer: D

Explanation:
Technical explanation
The host entity represents the local node on which the selected Cilium endpoint resides. It also includes processes and containers using the local host network namespace. Therefore, A reproduces the official entity definition accurately.
The remote-node entity does not represent arbitrary unmanaged endpoints. It represents hosts other than the local node across the local cluster and connected clusters, including host-networked containers on those nodes. Unmanaged endpoints instead have the reserved unmanaged identity.
Option C gives the definition of the separate kube-apiserver entity, not cluster . The cluster entity is the logical collection of endpoints and reserved identities inside the local cluster, including Cilium-managed endpoints, unmanaged local endpoints, hosts, remote nodes, health, ingress, initialization, and kube-apiserver identities. Current documentation separately provides a cluster-mesh entity for endpoints in connected clusters.
Option D confuses all with world . world represents endpoints outside the cluster. all covers all identities and is not simply equivalent to the IPv4 CIDR 0.0.0.0/0 , particularly in identity-aware, node, and IPv6 contexts.
