Topology Background:
A network security engineer configures an IKEv2 site-to-site IPsec tunnel between two Cisco Catalyst 8300 edge routers. When testing the connection, the IKEv2 Phase 1 negotiation fails during the initial exchange. The engineer notices that Router-A defines encryption algorithm aes-gcm-256 inside crypto ikev2 proposal PROP-A, but does not configure an integrity algorithm. Router-B rejects the proposal. Why did Router-B accept proposals utilizing aes-cbc-256 with sha256 but reject aes-gcm-256?
- A. AES-GCM is only supported over unencrypted GRE tunnels.
- B. AES-GCM is an Authenticated Encryption with Associated Data (AEAD) cipher that provides built-in integrity; if an explicit integrity algorithm is configured alongside an AEAD cipher, or if the peer demands a separate integrity hash, negotiation fails.
- C. Cisco IOS-XE requires 3DES fallback whenever IKEv2 is enabled.
- D. IKEv2 proposals cannot support AES key lengths greater than 128 bits.
Correct Answer: B
Detailed Technical Explanation:
- Under IKEv2 (RFC 7296), AEAD ciphers (such as AES-GCM and AES-CCM) combine data confidentiality and message integrity authentication into a single cryptographic operation.
- When configuring an IKEv2 proposal using an AEAD cipher like
aes-gcm-256, the integrity algorithm is integrated natively. Configuring a separate integrity hash (such assha256orsha512) is invalid or incompatible with non-AEAD proposals. - Both peers must agree on either an AEAD cipher (with no external integrity setting) or a non-AEAD cipher (e.g.,
aes-cbc-256) paired with an explicit integrity hash (e.g.,sha256). - Distractor analysis: Option A is false; AES-GCM is standard for IPsec ESP and IKEv2. Option C is false; 3DES is deprecated. Option D is false; 256-bit keys are fully supported.
Topology Background:
An enterprise operates a DMVPN network connecting 100 branch spokes through a central Hub router. The network architect upgrades the deployment from Phase 2 to Phase 3 to enhance routing scalability and allow dynamic spoke-to-spoke direct tunnels. Which two configuration statements are mandatory on the Hub and Spoke tunnel interfaces, respectively, to enable DMVPN Phase 3?
- A. Hub:
ip nhrp shortcut| Spoke:ip nhrp redirect - B. Hub:
ip nhrp redirect| Spoke:ip nhrp shortcut - C. Hub:
ip nhrp map multicast dynamic| Spoke:tunnel mode gre multipoint - D. Hub:
ip nhrp interest| Spoke:ip nhrp holdtime 3600
Correct Answer: B
Detailed Technical Explanation:
- In DMVPN Phase 3:
- The Hub must be configured with
ip nhrp redirect. When transit data between two spokes passes through the Hub on the mGRE interface, the Hub recognizes that both spokes reside in the same NHRP network and transmits an NHRP Redirect packet to the source spoke. - The Spoke must be configured with
ip nhrp shortcut. Upon receiving the redirect, the ingress spoke initiates an NHRP resolution request directly to the target spoke's public NBMA IP, installs an NHRP-generated routing shortcut (with anHflag in the routing table) into CEF, and forwards packets directly over a newly negotiated dynamic spoke-to-spoke IPsec tunnel.
- The Hub must be configured with
- Distractor analysis: Option A reverses the hub and spoke roles. Option C configures basic multicast mapping, which is required in all phases but does not enable Phase 3 shortcuts. Option D does not configure shortcut routing.
Topology Background:
A security engineer designs a hub-and-spoke VPN utilizing Cisco FlexVPN. The Hub router terminates connections from hundreds of dynamic IP branch routers. The design mandates that per-spoke QoS queuing, distinct VRF assignments, and dynamic BGP routing must be applied to each spoke tunnel dynamically as it connects. Which FlexVPN construct on the Hub provides dynamically instantiated virtual interfaces for each incoming spoke session?
- A. Static Virtual Tunnel Interface (SVTI)
- B. Dynamic Virtual Tunnel Interface (DVTI) derived from a
virtual-templateinterface - C. Point-to-Point GRE Tunnel
- D. Crypto Map with dynamic ACLs
Correct Answer: B
Detailed Technical Explanation:
- FlexVPN replaces legacy Phase 1/Phase 2 crypto maps and DMVPN complexity with IKEv2-based point-to-point and multipoint tunnel interfaces.
- On the FlexVPN Hub, incoming dynamic connections are terminated using a
virtual-templateinterface. - When a remote spoke authenticates via IKEv2, the Hub automatically clones a dedicated Dynamic Virtual Tunnel Interface (DVTI) (e.g.,
Virtual-Access1) from the virtual-template. This dedicated virtual-access interface inherits the spoke's authorization attributes (such as RADIUS-pushed QoS policies, ACLs, and VRF forwarding), enabling individual per-spoke queuing and dynamic routing. - Distractor analysis: Option A (SVTI) is static and requires manual configuration for each remote site. Option C is a legacy static GRE tunnel. Option D uses deprecated crypto maps that lack native multicast and dynamic routing support.
Topology Background:
A multinational financial institution runs an internal, private MPLS Layer 3 VPN provided by a trusted carrier. Security regulations mandate end-to-end payload encryption across the WAN. However, the enterprise cannot use traditional point-to-point IPsec overlays because the carrier's quality of service (QoS) and MPLS core label-switching rely on inspecting the enterprise's original Layer 3 IP headers. Which VPN technology satisfies this requirement?
- A. Dynamic Multipoint VPN (DMVPN Phase 3)
- B. Group Encrypted Transport VPN (GETVPN) utilizing Group Domain of Interpretation (GDOI)
- C. SSL Remote Access VPN
- D. WireGuard over GRE
Correct Answer: B
Detailed Technical Explanation:
- GETVPN (Group Encrypted Transport VPN) is a tunnel-less, any-to-any IPsec technology designed for private WANs (like enterprise MPLS L3VPN or private Metro Ethernet):
- Header Preservation: GETVPN encrypts the IP payload using standard ESP, but preserves the original enterprise source and destination IP addresses in the outer IP header. This allows carrier MPLS routers to maintain QoS markings and native routing without tunneling overhead.
- GDOI Protocol: Group Members (GMs) register with a centralized Key Server (KS) via the GDOI (Group Domain of Interpretation) protocol (RFC 6407). The Key Server pushes a shared Security Association (Traffic Encryption Key - TEK, and Key Encryption Key - KEK) to all group members, enabling seamless full-mesh communication without peer-to-peer point-to-point IPsec tunnel negotiation.
- Distractor analysis: Options A, C, and D encapsulate packets with new outer tunnel headers, hiding original IP headers and increasing MTU overhead.
Topology Background:
Remote employees using Cisco Secure Client (AnyConnect) report that VoIP softphone audio is choppy and exhibits severe packet latency spikes over the VPN during periods of public internet congestion. The network administrator inspects the ASA/FTD headend and notices that AnyConnect is connected using standard TLS. How does enabling Datagram Transport Layer Security (DTLS) resolve this real-time multimedia performance issue?
- A. DTLS forces all voice traffic over unencrypted UDP port 53.
- B. DTLS uses UDP as its transport protocol instead of TCP, eliminating TCP retransmission overhead and TCP meltdown effects for latency-sensitive real-time audio/video packets.
- C. DTLS automatically compresses audio files by 80%.
- D. DTLS converts all incoming audio streams into SIP signaling messages.
Correct Answer: B
Detailed Technical Explanation:
- Standard SSL VPN uses TCP (port 443) as the transport layer. When real-time UDP audio (like RTP) is encapsulated inside a TCP tunnel traversing an unreliable internet link, dropped packets trigger TCP retransmissions and exponential backoff (TCP meltdown), causing severe audio stutter and delay.
- DTLS (Datagram Transport Layer Security): Provides TLS-equivalent encryption over UDP (typically UDP port 443).
- When DTLS is enabled, AnyConnect uses DTLS/UDP for all data payload forwarding. Dropped audio packets are simply discarded rather than retransmitted, preserving real-time voice and video quality while using TLS/TCP strictly as a control and fallback channel.
- Distractor analysis: Option A is insecure. Option C fabricates compression percentages. Option D misidentifies transport protocols as application converters.
Topology Background:
An enterprise configures AnyConnect on a Cisco ASA. Security compliance requires that all corporate intranet traffic (10.0.0.0/8 and 172.16.0.0/12) must be routed through the encrypted VPN tunnel, while general public internet browsing (e.g., YouTube, Wikipedia) must route directly out the user's local home broadband gateway to conserve corporate internet bandwidth. How should the administrator configure split tunneling in the ASA Group Policy?
- A. Set
split-tunnel-policy tunnelall - B. Set
split-tunnel-policy tunnelspecified(Split Tunnel Include) and attach a standard access-list matching10.0.0.0/8and172.16.0.0/12 - C. Set
split-tunnel-policy excludespecifiedand match all private addresses - D. Disable NAT on the corporate ASA edge firewall
Correct Answer: B
Detailed Technical Explanation:
- In Cisco ASA Group Policies:
split-tunnel-policy tunnelspecified(Split Tunnel Include): Instructs the AnyConnect client to push only the IP networks specified in the referenced access-list into the encrypted VPN adapter's routing table.- Packets destined for
10.0.0.0/8and172.16.0.0/12traverse the secure tunnel, while all unlisted destinations (the global internet) continue routing out the client's local physical network adapter.
- Distractor analysis: Option A forces all traffic through the corporate headend, saturating WAN bandwidth. Option C routes all traffic through the tunnel except the listed subnets. Option D breaks internet connectivity.
Topology Background:
An organization deploys Cisco AnyConnect on an ASA 5525-X and wants to integrate with Microsoft Entra ID (Azure AD) to enforce corporate Multi-Factor Authentication (MFA) and Conditional Access policies. What authentication protocol and trust exchange must be established between the Cisco ASA and the cloud Identity Provider (IdP)?
- A. RADIUS with PAP authentication
- B. SAML 2.0 (Security Assertion Markup Language) utilizing cryptographic Metadata XML exchanges and IdP signing certificates
- C. Kerberos Ticket Granting Server over UDP port 88
- D. LDAP plain-text binding over TCP port 389
Correct Answer: B
Detailed Technical Explanation:
- SAML 2.0: The industry-standard federation protocol for web-based and client-based Single Sign-On (SSO) and Multi-Factor Authentication:
- The Cisco ASA acts as the Service Provider (SP).
- Microsoft Entra ID acts as the Identity Provider (IdP).
- The trust relationship is configured by exchanging SAML Metadata XML files containing entity IDs, Assertion Consumer Service (ACS) URLs, and cryptographic X.509 signing certificates.
- When the user connects via AnyConnect, the client displays the embedded IdP login portal, where the user completes password and MFA challenges, and the IdP returns a signed SAML assertion verifying identity.
- Distractor analysis: Option A (RADIUS) cannot handle modern browser-based MFA redirects. Option C requires direct local Kerberos domain connectivity. Option D transmits plaintext credentials without MFA.
Topology Background:
An enterprise terminates high-throughput IPsec tunnels across a QoS-enabled carrier network. During peak usage, network monitoring reports high volumes of discarded packets with the error: %CRYPTO-4-PKT_REPLAY_ERR: decrypt: packet failed anti-replay check. Network analysis confirms packets are not malicious, but voice and data packets are arriving out of sequence due to upstream QoS priority queuing. How can the engineer tune the IPsec anti-replay mechanism to prevent legitimate out-of-order packets from being discarded?
- A. Disable IPsec encryption completely.
- B. Expand the IPsec Anti-Replay window size using
crypto ipsec security-association replay window-sizeor disable anti-replay on the crypto map. - C. Force all packets to be fragmented into 64-byte cells.
- D. Change the IKEv2 dead peer detection timer to 1 second.
Correct Answer: B
Detailed Technical Explanation:
- IPsec ESP includes a 32-bit or 64-bit sequence number in every packet header to protect against replay attacks (where an adversary captures and retransmits valid packets).
- The receiving router maintains a sliding Anti-Replay Window (default is typically 64 or 128 packets). If an out-of-order packet arrives with a sequence number older than the window boundary, it is dropped as a suspected replay.
- In QoS networks where priority packets jump ahead of bulk packets, legitimate packets can arrive out of sequence beyond the default window. Increasing the window size (e.g., to 512 or 1024 packets via
crypto ipsec security-association replay window-size 1024) accommodates out-of-order arrival without discarding valid traffic. - Distractor analysis: Option A destroys security. Option C worsens fragmentation. Option D causes tunnel teardowns.
Topology Background:
A network administrator configures an AnyConnect XML Client Profile (AnyConnect-Profile.xml) to enforce auto-reconnect, configure backup headend server lists, and lock down user preferences. How does the Cisco ASA headend deploy this XML profile to connecting remote clients?
- A. The administrator must physically copy the XML file onto every remote laptop via a USB flash drive.
- B. The profile is uploaded to the ASA flash file system, linked to the AnyConnect Group Policy, and automatically downloaded by the AnyConnect client during initial SSL/TLS session establishment.
- C. The XML profile is pushed via Active Directory Group Policy Objects (GPO) only.
- D. The client fetches the profile using TFTP from the root internet servers.
Correct Answer: B
Detailed Technical Explanation:
- Cisco ASA and FTD provide centralized client profile provisioning:
- The administrator creates the AnyConnect profile XML file using the AnyConnect Profile Editor in ASDM or FMC.
- The XML file is uploaded to the headend and linked to a specific Group Policy (
webvpn > anyconnect profiles value <profile_name>). - When an AnyConnect client authenticates, the headend compares the client's local profile checksum with the headend version. If newer, the client downloads and activates the updated XML profile automatically before establishing the data tunnel.
- Distractor analysis: Option A is inefficient and unmanageable. Option C is an optional external method, not the native Cisco mechanism. Option D is fictional.
Topology Background:
A site-to-site VPN tunnel between an ASA and an IOS-XE router fails to pass traffic. A security engineer issues the following command on the IOS-XE router:
Router# show crypto ipsec sa peer 198.51.100.1
The output shows:
-
#pkts encaps: 1540, #pkts encrypt: 1540, #pkts digest: 1540 -
#pkts decaps: 0, #pkts decrypt: 0, #pkts verify: 0What do these packet counter statistics indicate? -
A. The tunnel is operating normally in full duplex mode.
-
B. Router is successfully encrypting and transmitting outbound traffic, but receiving zero inbound IPsec packets from the peer (likely due to an upstream ISP blocking ESP/UDP 500/4500 or peer routing failure).
-
C. The IKEv2 pre-shared key was entered incorrectly on both sides.
-
D. The physical link is down.
Correct Answer: B
Detailed Technical Explanation:
- In
show crypto ipsec sa:#pkts encrypt: Counts packets matching the local crypto access-list that were encapsulated and transmitted outbound.#pkts decrypt: Counts incoming ESP packets that were received, verified, and decrypted.
- A high encrypt count paired with
#pkts decaps: 0indicates a classic one-way communication failure:- The local router is actively transmitting encrypted packets.
- The remote peer is either not sending return packets, its return routing is broken, or an intermediate firewall/ISP is dropping ESP (IP protocol 50) or UDP 4500 return traffic before it reaches the local router.
- Distractor analysis: Option A is false because full duplex requires both transmit and receive. Option C is false; if keys were mismatched, IKE SAs would not form and IPsec SAs would not exist. Option D is false because the router is actively transmitting packets.
