A company is designing a small office network. They need a topology that provides redundancy so that if one cable fails, the network remains operational. Which topology best meets this requirement?

Star topology, where all devices connect to a central switch.

Ring topology, where each device connects to two neighbors.

Mesh topology, where each device has multiple connections to other devices.

Bus topology, where all devices share a single backbone cable.

A network administrator is capturing packets on a server and sees a frame with an Ethernet header, an IP header, and a TCP header. The payload contains an HTTP request. Which statement correctly describes the encapsulation process that produced this frame?

The IP packet was encapsulated in a TCP segment, then an Ethernet frame, then HTTP data

The HTTP data was encapsulated in a TCP segment, then an IP packet, then an Ethernet frame

The Ethernet frame was encapsulated in an IP packet, then a TCP segment, then HTTP data

The TCP segment was encapsulated in an Ethernet frame, then an IP packet, then HTTP data

A network technician is troubleshooting a problem where a user can ping a server by IP address but cannot connect to a database application running on the same server. Which OSI layer is most likely the source of the problem?

Data Link layer, because the MAC address is incorrect.

Transport layer, because the database application uses a specific port that may be blocked.

Network layer, because IP addressing is incorrect.

Physical layer, because the cable is faulty.

A user reports that typing 'intranet.corp.example' in a browser fails, but typing the IP address 10.10.10.5 works. Other users can reach the site by name. The DNS server is authoritative for corp.example. Which step should the administrator take first?

Flush the DNS cache on the DNS server

Verify the user's DNS resolver settings and run nslookup for the hostname

Check the DNS server's zone transfer settings

Part of the Network and Systems Security domain, which makes up ~28% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 120-minute exam (~50–80 total, ~14–22 in this domain), expect 5–7 from this objective — we provide 53 practice questions to prepare you well beyond it.
