CCIEPrep: CCIE Study Toolkit
iOS Universel / Education
Prepare for the most prestigious networking credential in IT with CCIEPrep— a complete, expert-level study companion built for every current CCIE track.
ALL 5 CCIE TRACKS IN ONE APP
CCIEPrep is the study companion and working toolkit for CCIE candidates and the practicing network engineers who already work with these technologies every day.
This is not a timed exam simulator. It's the kit you'll keep open during study sessions, change windows, and 2 AM bridge calls.
▸ Sample Questions
128 study questions across all five CCIE tracks — Enterprise Infrastructure, Security, Data Center, Service Provider, and Collaboration. Browse by track, difficulty, or topic. Tap any answer and the explanation appears immediately. No timer, no score percentage, no pass/fail verdict — just focused study material.
▸ Six Live Network Calculators
Real interactive tools you'll use during a change window:
IPv4 Subnet — network, broadcast, host range, mask, wildcard, class, private-space flag
VLSM Splitter — type host counts, get an aligned packing of child blocks
Supernet / CIDR Aggregator — collapse a list of prefixes into one covering supernet
IPv6 Helper — expand, compress, classify scope, derive EUI-64 from a MAC
MTU / MSS — choose a tunnel overhead profile (GRE, IPsec, DMVPN, VXLAN, PPPoE, MPLS), get the right MSS clamp
Wildcard / Mask — three-way converter between prefix length, dotted mask, and ACL wildcard
Every result has a Copy button. Drop the number straight into the CLI.
▸ Configuration Recipes
A curated library of copy-paste configuration snippets organized by category: OSPF area baselines, iBGP route reflectors, EIGRP named-mode, prefix-list filtering, MSTP regions, LACP port-channels, port-security, IKEv2 site-to-site VPN, LLQ + CBWFQ QoS, NAT PAT, NTP with authentication, DHCP, WPA3 wireless, FlexConnect, NETCONF/YANG enable, Python Netmiko, Ansible playbooks.
▸ Troubleshooting Playbooks
Interactive step-by-step decision trees for the situations that actually happen on production networks: OSPF neighbors stuck in EXSTART, BGP sessions that won't establish, STP convergence storms, IPsec tunnels up with no traffic, Wi-Fi association failures, and the perennial "the app is slow — is it the network?" investigation. Each step suggests a command you can run; tap your observation to advance.
▸ Daily Concept Cards
One thoughtful, deeply technical networking concept per day, plus a full searchable archive. Why STP TCNs flush MAC tables. Why bit 7 of the EUI-64 gets flipped. PHP vs explicit-null in MPLS. Airtime fairness in Wi-Fi. Star the ones worth coming back to.
▸ Engineer's Journal
A private, on-device change log. Tag entries (Change, Incident, Learning, Note), search the history, and build a personal record of what you did and what you learned. Persisted locally — no cloud, no account, no sync.
Built for the work
Universal iPhone + iPad with full portrait and landscape support
Warm copper-on-slate dark interface — easy on the eyes during long sessions
Every result is copyable
All data stored locally on this device
No ads, no tracking, no in-app purchases, no account required
CCIEPrep is a study aid and reference toolkit. The sample questions help you check understanding; the calculators, recipes, playbooks, and journal are the same kit you'll keep using on the job after you pass.
