PPPoE (Point-to-Point Protocol over Ethernet) uses a discovery stage before establishing the actual PPP session. The correct sequence is:

Initialization → Client sends a PADI (PPPoE Active Discovery Initiation)

Offer → Server responds with PADO (PPPoE Active Discovery Offer)

Request → Client sends PADR (PPPoE Active Discovery Request)

Session Confirmation → Server sends PADS (PPPoE Active Discovery Session-confirmation)

A.✘Wrong sequence

B.✔Correct – Matches the technical flow: PADI → PADO → PADR → PADS

C.✘Incorrect order

D.✘Incorrect order

Extract from MTCNA Course Material – PPPoE Process:

“The PPPoE discovery stage includes PADI, PADO, PADR, and PADS messages. This translates to Initialization, Offer, Request, Session confirmation.”

Extract from MikroTik Wiki – PPPoE Protocol:

“The discovery stage is used to establish a PPPoE session and includes four steps: PADI, PADO, PADR, and PADS.”

The local PPP database in MikroTik allows control over authentication and access for PPP-based services such as PPTP, L2TP, PPPoE, and SSTP. Several configuration options can be specified per user or profile.

A.✔Correct – You can use the "only-one" setting in PPP profiles to allow/deny multiple logins for the same user.

B.✔Correct – Under the "service" parameter in /ppp secret, you can restrict allowed protocols (e.g., enable PPPoE, PPTP, and disable L2TP).

C.✘Incorrect – Data transfer limits (Rx/Tx) are not enforced directly in PPP profiles or secrets. This is usually handled via queues or hotspot limitations.

D.✔Correct – By setting the "service" to only "pppoe", all other PPP types will be denied.

E.✘Incorrect – Access to services like telnet is managed via firewall rules or user groups, not in PPP profiles.

Extract from Official MTCNA Course Material – PPP Profiles:

“PPP Profiles control session parameters. You can limit simultaneous logins, restrict service types (e.g., PPPoE), and set IP pools.”

Extract from René Meneses MTCNA Study Guide – PPP Configuration:

“Use the ‘only-one’ flag to control concurrent logins. The ‘service’ field allows or restricts protocol types per user.”

Extract from Terry Combs MTCNA Notes – PPP Features:

“To allow a user access only via PPPoE or PPTP, adjust the service types in /ppp secret.”

MikroTik RouterOS supports running multiple dynamic routing protocols simultaneously, including RIP, OSPF, and BGP. They are independent processes and can be configured in parallel. This is commonly used in complex network environments or during routing migrations.

A.✔FALSE – You can run OSPF and RIP at the same time.

B.✘TRUE – Incorrect; both protocols are fully supported to coexist.

Extract from MTCNA Course Material – Dynamic Routing:

“RouterOS supports multiple dynamic routing protocols, including simultaneous use of RIP and OSPF.”

Extract from René Meneses Study Guide – Routing Protocols:

“You can configure both RIP and OSPF to run at the same time on a single router.”

Extract from MikroTik Wiki – Routing Overview:

“RouterOS allows multiple routing protocols to operate concurrently.”
