DNS primarily uses UDP port 53 for most query/response operations. However, TCP port 53 is also used, particularly for larger responses (such as DNS zone transfers or DNSSEC).

A.✔UDP – Used for standard DNS queries due to lower overhead.

B.✔TCP port 53 – Used when UDP is insufficient, especially for zone transfers (AXFR/IXFR).

Extract from MTCNA Course Material – DNS and Networking Services:

“DNS typically uses UDP/53, but falls back to TCP/53 for larger queries or zone transfers.”

Extract from MikroTik Wiki – DNS Settings:

“DNS uses UDP for general queries. TCP is used when UDP cannot accommodate the size of the response.”

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.”

Only tunnel types built on PPP support authentication with username and password:

A.✔PPPoE – Built on PPP, uses CHAP, PAP authentication.

B.✔OpenVPN – Supports user/password login for client authentication.

C.✘IPIP – A stateless Layer 3 tunnel; no authentication support.

D.✔PPTP/L2TP – Both are PPP-based and support username/password authentication.

E.✘EoIP – MikroTik proprietary Layer 2 tunnel; no username/password authentication.

Extract from MTCNA Course Material – Tunnel Types:

“PPPoE, PPTP, and L2TP are PPP-based and support user/password authentication. IPIP and EoIP do not.”

Extract from René Meneses Study Guide – Tunnel Protocols:

“Authentication (PAP/CHAP) is part of PPP. Use PPPoE, PPTP, L2TP, or OpenVPN for user logins.”

Extract from MikroTik Wiki – Tunnel Protocols Overview:

“Only PPP-based tunnels support authentication via username/password.”
