350-701 Quick Quiz — 10 Questions

Question 1

A network engineer is troubleshooting an IPsec VPN tunnel that fails to establish. The configuration includes a crypto map with a matching access list. Which command should be used to verify the security associations and error counters for the IPsec phase?

Accepted Answer

show crypto ipsec sa. The 'show crypto ipsec sa' command displays the IPsec security associations (SAs) and their associated packet/byte counters, including error counters such as 'pkts encaps failed' and 'pkts decap failed'. This directly verifies the IPsec Phase 2 SAs and identifies failures in encryption/decryption or integrity checks, which is essential for troubleshooting a tunnel that fails to establish.

Answer

show crypto engine statistics

Answer

debug crypto isakmp

Answer

show crypto isakmp sa

Question 2

An engineer is configuring Cisco ISE for guest access. The requirement is that guests must accept an acceptable use policy (AUP) before being granted network access. Which portal type should be used?

Accepted Answer

Self-registration guest portal. The self-registration guest portal is the correct choice because it allows guests to create their own credentials and, crucially, includes a configurable step where the user must accept an Acceptable Use Policy (AUP) before being granted network access. This portal type is specifically designed for scenarios where guests self-onboard and must acknowledge a policy, which is a core requirement for compliance in many guest access deployments.

Answer

Sponsored guest portal

Answer

Hotspot guest portal

Answer

BYOD portal

Question 3

A financial company has a data center with Cisco FTD firewalls in a high-availability pair. They use Cisco ISE for network access control and Cisco Stealthwatch for network visibility. Recently, they deployed a new web application that is accessed by both internal employees and external customers. The application uses HTTPS on port 443. After deployment, the security team notices that the FTD is dropping some HTTPS sessions that appear legitimate. The drops are inconsistent and seem to occur only during peak hours. The FTD logs show the drop reason as 'TCP state violation'. The team has verified that the web server and clients are configured correctly. The Stealthwatch reports show no anomalies. What is the most likely cause and solution?

Accepted Answer

Configure TCP state bypass on the FTD for the web server traffic. The 'TCP state violation' drops during peak hours indicate that the FTD's stateful inspection engine is seeing TCP segments that do not match the expected state machine, likely due to asymmetric routing or session timeouts under load. Configuring TCP state bypass for the web server traffic disables stateful inspection for those flows, allowing the firewall to forward packets based on ACLs alone without tracking TCP states, which resolves the issue without compromising security for legitimate traffic.

Answer

Enable SSL decryption to inspect the encrypted traffic

Answer

Increase the TCP timeout values on the FTD to accommodate longer sessions

Answer

Block all traffic to the web server except from trusted IPs

Question 4

A company is implementing Cisco Umbrella to provide DNS-layer security. They want to block access to known malicious domains while allowing all other traffic. Which policy configuration should be used?

Accepted Answer

Create a block list with known malicious domains. Cisco Umbrella's DNS-layer security operates by intercepting DNS queries and comparing them against policy-defined lists. A block list containing known malicious domains is the correct approach because Umbrella will block DNS resolution for those domains while allowing all other traffic to pass through normally. This aligns with the requirement to block only malicious destinations without affecting access to legitimate sites.

Answer

Enable selective proxy for all traffic

Answer

Create an allow list with only safe domains

Answer

Use a custom policy with both allow and block lists

Question 5

Which THREE are characteristics of Cisco Stealthwatch?

Accepted Answer

Can integrate with Cisco ISE for automated threat response. Option A is correct because Cisco Stealthwatch can integrate with Cisco ISE (Identity Services Engine) via pxGrid or REST API to enable automated threat response. When Stealthwatch detects anomalous behavior, it can trigger ISE to enforce policy changes such as quarantining an endpoint or dynamically applying a security group access control list (SGACL), closing the loop between detection and remediation.

Answer

Acts as a next-generation firewall

Answer

Functions as an intrusion prevention system (IPS)

Question 6

Which TWO are valid methods for implementing Network Admission Control (NAC) in a Cisco environment?

Accepted Answer

802.1X authentication. 802.1X authentication is a valid NAC method because it enforces port-based access control by requiring end devices to authenticate via EAP (Extensible Authentication Protocol) before gaining network access. It integrates with a RADIUS server (e.g., Cisco ISE) to validate credentials and dynamically assign VLANs or ACLs based on policy, making it a core NAC technology.

Answer

Dynamic ARP Inspection (DAI)

Answer

IP source guard

Answer

DHCP snooping

Question 7

A network administrator is configuring Cisco ASA with FirePOWER services. The administrator wants to inspect SSL traffic but is concerned about certificate pinning in modern applications. Which action should the administrator take to ensure that SSL inspection does not break applications that use certificate pinning?

Accepted Answer

Create an SSL decryption rule to exclude traffic from applications known to use certificate pinning. Option C is correct because certificate pinning hardcodes the expected certificate or public key within an application. If the ASA decrypts and re-encrypts the traffic using a different certificate (even one signed by a trusted CA), the pinned certificate will not match, causing the application to reject the connection. By creating an SSL decryption rule that excludes traffic from applications known to use certificate pinning, the administrator avoids breaking those applications while still inspecting other SSL traffic.

Answer

Configure SSL inspection to bypass all traffic to avoid any issues

Answer

Install a custom root CA on all clients and configure the ASA to use that CA

Answer

Use a decryption policy that decrypts the traffic but does not re-encrypt

Question 8

A network engineer is troubleshooting an issue where users on VLAN 10 cannot access the internet, but they can reach internal resources. The firewall is configured with a default route pointing to the ISP router. The engineer notices that NAT is configured but traffic is not being translated. Which configuration is most likely missing?

Accepted Answer

An ACL to match the traffic to be translated. For NAT to translate traffic, the firewall must know which traffic to translate. An ACL is used to match the source IP addresses (or networks) that should be translated. Without an ACL applied to the NAT rule, the firewall has no criteria to identify traffic from VLAN 10 for translation, so packets are forwarded without NAT, causing internet access to fail while internal routing works.

Answer

A NAT pool with available public IP addresses

Answer

Port Address Translation (PAT) configuration

Answer

A route map to apply NAT based on destination

Question 9

A network administrator is configuring IKEv2 on a Cisco router and wants to ensure that the router does not initiate connections but only responds to incoming IKEv2 requests. Which configuration command should be applied?

Accepted Answer

crypto ikev2 passive. The 'crypto ikev2 passive' command configures the router to only respond to incoming IKEv2 requests and never initiate its own IKEv2 connections. This is essential for scenarios where the router must act as a responder only, such as in hub-and-spoke VPN topologies where the hub should not initiate tunnels.

Answer

crypto ikev2 no initiate

Answer

crypto ikev2 limit max-incoming-sa 10

Answer

crypto ikev2 limit max-negotiations 10

Question 10

A multinational corporation is migrating its on-premises data center to a public cloud provider. The security policy requires that all traffic between cloud VPCs and the on-premises network must be inspected by a next-generation firewall (NGFW) deployed in the cloud. The on-premises network uses BGP for dynamic routing. Which design meets the requirement while minimizing latency and administrative overhead?

Accepted Answer

Deploy a transit VPC with an NGFW instance and configure BGP dynamic routing between the transit VPC, other VPCs, and the on-premises network.. Option A is correct because a transit VPC with an NGFW instance allows centralized traffic inspection while using BGP dynamic routing to exchange routes between the transit VPC, other VPCs, and the on-premises network. This design minimizes administrative overhead by avoiding static route management and reduces latency by keeping inspection within the cloud, rather than hair-pinning traffic on-premises. BGP enables automatic failover and route propagation, meeting the dynamic routing requirement.

Answer

Use AWS Transit Gateway with static routes pointing to the NGFW instance for inspection.

Answer

Create a site-to-site VPN between each VPC and the on-premises network, and configure the NGFW on-premises.

Answer

Use AWS Direct Connect to connect all VPCs to the on-premises network and place the NGFW on-premises.
