Network Associate Skills
1. Cisco IOS
Cisco IOS (and IOS XE) drives most Cisco routers and many switches, powering routing, switching, and a stack of network services. It’s the daily interface for configuration, management, and troubleshooting across a huge install base.
Why It's Important
It’s the operating ground you’ll stand on in many enterprise networks. Mastery here unlocks fast configuration, clean change control, and calm troubleshooting when links flap or routing gets messy.
How to Improve Cisco IOS Skills
Command fluency: Drill show, debug, and configure commands until they’re instinct. Know where to look first.
Hands-on labs: Build topologies in Packet Tracer, CML, or EVE-NG and break them on purpose. Then fix them.
Modern features: Learn IOS XE specifics, model-driven telemetry, NETCONF/RESTCONF, EEM, and smart licensing basics.
Troubleshooting patterns: Develop a playbook for interface, Layer 2, and routing issues. Inputs, hypotheses, quick tests, rollback.
Cert tracks: Use CCNA/CCNP blueprints as a capability map and self-assessment loop.

2. Juniper Junos
Junos OS powers Juniper routers, switches, and security platforms with a consistent CLI, a clean config hierarchy, and strong automation hooks. It’s terse, predictable, and built for scale.
Why It's Important
Plenty of carriers and enterprises run Juniper at the core or edge. Knowing Junos means cross-vendor agility, better job coverage, and less fear when facing a mixed environment.
How to Improve Juniper Junos Skills
Hierarchy mindset: Get comfortable with set/edit/delete, candidate vs active config, and commit confirmed.
Practice labs: Use vSRX/vMX or vendor labs to build BGP, OSPF, and firewall policies. Change. Revert. Repeat.
Commit checks: Embrace commit check, commit synchronize, and rollback points. Save yourself from late-night outages.
Automation: Explore Junos automation with event policies, Python/Ansible, and NETCONF.
Certification path: Track JNCIA-Junos, then JNCIS/JNCIP aligned to your track (routing, switching, security).

3. BGP
BGP (Border Gateway Protocol) moves routes between autonomous systems and across large networks. It sets the paths the internet actually walks on.
Why It's Important
It’s the backbone routing protocol. Master it, and you can shape traffic flow, defend your prefixes, and keep upstreams honest.
How to Improve BGP Skills
Policy discipline: Filter on ingress and egress. IRR-based prefix lists, max-prefix limits, reject bogons, no default acceptance by accident.
Attributes that matter: Local-pref beats AS_PATH; MED, communities, and AS path prepending steer traffic when used intentionally.
Aggregation: Summarize where possible to shrink tables and steady convergence. Don’t punch holes unless you must.
Stability and speed: Use BFD for faster failure detection, tune keepalive/hold timers prudently, and avoid aggressive route damping unless you know the blast radius.
Security: Enable RPKI origin validation and drop invalids. Add TTL security (GTSM). Authenticate sessions (TCP-AO or MD5). BGPsec exists but remains limited in deployment—prioritize what’s widely supported.
Monitoring: Track session state, flaps, path changes, and prefix counts. Baseline now, catch drift later.

4. OSPF
OSPF is a link-state IGP that keeps a live map of your domains and computes shortest paths. It’s tidy when designed right and unforgiving when it’s not.
Why It's Important
It scales well inside an autonomous system, converges fast, and gives you sharp tools for summarization and area separation.
How to Improve OSPF Skills
Area design: Keep a lean backbone (Area 0). Use stub/NSSA where sensible. Summarize at ABRs. Avoid needless area count.
Interface hygiene: Consistent network types, matching MTU, and clean DR/BDR expectations on multiaccess segments.
Timers and pacing: Tune hello/dead timers with caution. Use SPF throttling and LSA pacing to calm churn.
Security: Use cryptographic authentication (MD5 or stronger where supported). Limit neighbors at L2. Consider BFD for quicker failure notice.
Keep it simple: Prune unused networks, retire stale configs, and document area boundaries and summaries.

5. MPLS
MPLS forwards packets using labels, not long lookups, and underpins VPNs, TE, and dependable core networks.
Why It's Important
It’s the engine for scalable transport, deterministic paths, and clean separation of customer or departmental traffic.
How to Improve MPLS Skills
IGP first: Solid OSPF or IS-IS design and fast convergence come before labels. Garbage in, garbage around.
Traffic Engineering: Use RSVP-TE or move toward Segment Routing (SR-MPLS) for simpler path control and easier scaling.
Resiliency: Fast reroute (LFA/TI-LFA) to slash failover time. Test blackhole scenarios before they find you.
QoS mapping: Map DSCP to EXP consistently. Reserve bandwidth where it matters. Don’t starve the control plane.
L3VPN hygiene: Sensible RDs, precise route-targets, and tidy import/export policies. Document tenants clearly.
Observe and plan: Monitor label distribution, PE/CE health, and path utilization. Capacity plan early, not in crisis.

6. VLANs
VLANs carve one physical network into many logical ones. Less noise, better control, cleaner segmentation.
Why It's Important
They confine broadcast domains, sharpen security boundaries, and give you a handle on traffic flows without extra cabling.
How to Improve VLANs Skills
Design with intent: Map VLANs to functions or trust zones, not whim. Keep IDs and names consistent everywhere.
Edge security: 802.1X, MAB as fallback, DHCP snooping, dynamic ARP inspection, IP source guard, storm control.
Trunks done right: Prune unused VLANs, tag the native VLAN or avoid it, and keep VLAN 1 out of harm’s way.
STP protections: BPDU Guard, Root Guard, and loop guard where appropriate. Elect roots on purpose.
Inter-VLAN routing: Prefer SVIs on Layer 3 switches over router-on-a-stick for throughput and simplicity.
Visibility: Use SPAN/RSPAN for troubleshooting. Baseline utilization and broadcasts. Document trunking and access ports.

7. QoS
QoS shapes, marks, and schedules traffic so time-sensitive flows don’t drown when congestion hits.
Why It's Important
Critical apps get priority. Voice stays crisp, video stays smooth, and batch jobs wait their turn.
How to Improve QoS Skills
Classify at the edge: Establish trust boundaries. Mark DSCP correctly as close to the source as possible.
Smart queuing: Use LLQ for real-time traffic, CBWFQ for everything else. Set strict but fair bandwidth guarantees.
Manage congestion: Apply WRED/ECN where it fits. Shape on egress, police sparingly on ingress.
End-to-end consistency: Keep QoS mappings aligned across WAN, campus, and data center. Audit regularly.
Measure and tune: Track latency, jitter, and loss. Adjust policies based on real data, not guesswork.

8. IPv6
IPv6 brings a gigantic address space, modern neighbor discovery, and a fresh chance to fix legacy design mistakes.
Why It's Important
Exhausted IPv4, expanding device counts, and new services make IPv6 not optional anymore. Deploy it intentionally.
How to Improve IPv6 Skills
Address planning: Allocate at least a /64 per subnet. Build a hierarchical plan using your ISP-assigned /48 or /56. Document it well.
Onboarding: Use SLAAC, DHCPv6, or both. Tune Router Advertisements. Plan DNS (AAAA), PTR, and search domains.
Security: Enforce IPv6 ACLs, RA Guard, DHCPv6 guard, and ND inspection where the platform supports it. Don’t forget logging.
Dual-stack strategy: Start dual-stack, validate parity, then consider IPv6-preferred or IPv6-only segments with NAT64/DNS64 where appropriate.
QoS and monitoring: Ensure tooling fully supports IPv6 flows, NetFlow/IPFIX export, and performance baselines.

9. Wireshark
Wireshark captures and dissects packets. With it, mysteries turn into timestamps, flags, and fields you can reason about.
Why It's Important
When logs lie or stay silent, packets tell the truth. It’s the ultimate magnifying glass for network behavior.
How to Improve Wireshark Skills
Filters and focus: Master capture and display filters. Get exactly what you need and ditch the noise.
Protocol fluency: Read TCP handshakes, TLS negotiation, DNS behavior, and oddities in ICMP like a story.
Visual tools: Use coloring rules, I/O graphs, flow graphs, and TCP stream analysis. Patterns jump out.
Expert Info: Let the expert system guide you toward malformed packets, retransmissions, and latency clues.
Automation: TShark and Lua scripts can batch analyses, extract KPIs, and speed root cause hunts.
Ethics and safety: Capture on SPAN/taps where permitted. Mind PII and credentials. Redact before sharing.

10. SNMP
SNMP monitors and manages network gear from a central point. Old but still everywhere.
Why It's Important
It feeds your NMS with health, counters, and traps, helping you spot trouble before tickets pile up.
How to Improve SNMP Skills
Go SNMPv3: Use authPriv where possible. Retire v1/v2c, or isolate and rate-limit them if you can’t yet.
Scope access: Restrict managers by source IP, SNMP views, and ACLs. Unique creds per device or group.
Harden and prune: Change defaults, rotate secrets, and disable SNMP on devices that don’t need it.
Traps vs polling: Balance informs/traps for events with sane polling intervals. Avoid query storms.
Look ahead: Evaluate model-driven telemetry (gNMI), NETCONF/RESTCONF for richer, more efficient data.

11. Firewall Management
Firewall management means shaping traffic with intent, policing edges, and keeping policies tight as networks evolve.
Why It's Important
It stands between your assets and a hostile internet. Do it well and incidents stay contained. Do it poorly and alerts scream.
How to Improve Firewall Management Skills
Policy hygiene: Recertify rules regularly. Remove or time-limit temporary access. Prefer application and user identity where supported.
Segmentation: Clear zones, least privilege between them, and explicit inter-zone policies. Block by default.
Change safety: Stage, validate, and schedule changes. Use dry runs and packet-tracer tools before committing.
Threat controls: Enable IPS, DNS/URL filtering, and threat intel feeds if available. Tune, don’t set-and-forget.
Decrypt with care: TLS inspection where policy allows, with privacy-sensitive exceptions. Watch certificate pinning.
Operations: Centralize logging, alert on anomalies, and test HA failover paths. Back up configs automatically.

12. VPN Configuration
VPNs create encrypted tunnels for remote access and site-to-site links, keeping data sealed as it crosses untrusted networks.
Why It's Important
Remote work, branch connectivity, third-party access—VPNs make them possible without leaking secrets.
How to Improve VPN Configuration Skills
Protocols and ciphers: Prefer IPsec with IKEv2 (AES-GCM, PFS) or WireGuard for simplicity and performance where supported.
Strong identity: Use certificate-based auth, short-lived credentials, and MFA via SAML/OIDC. Bind keys to devices when possible.
Routing approach: Route-based VPNs simplify scale. Control prefixes tightly. Consider full-tunnel for security or split-tunnel for performance, justified by risk.
Stability: Tune DPD/keepalives, set reasonable rekey timers, and enable tunnel monitoring and automatic failover.
Client posture: Always-on VPN where needed, device compliance checks, and per-app VPN on mobile.
Leak prevention: Enforce DNS over the tunnel, block traffic on disconnect (kill switch), and clamp MSS to fit path MTU.
